Subsequently, a configuration example of the control unit 20 will be described. The control unit 20 includes a shooting data acquisition unit 21, an event detection unit 22, a recording control unit 23, a buffer memory 24, a reproduction control unit 25, and a detection unit 26. Each component constituting the control unit 20 such as the shooting data acquisition unit 21, the event detection unit 22, the recording control unit 23, the reproduction control unit 25, and the detection unit 26 executes a program stored in the memory by the processor. It may be software or a module that executes processing according to the above. Or each component which comprises the control part 20 may be hardware, such as a circuit or a chip | tip.
撮影データ取得部21は、カメラ31において生成された映像データ及びマイクロフォン32において生成された音声データを取得する。映像データ及び音声データを含むデータは、撮影データと称されてもよい。つまり、撮影データ取得部21は、カメラ31及びマイクロフォン32から撮影データを取得すると言い換えられてもよい。また、撮影データは、少なくとも映像データを含むデータであってもよい。つまり、撮影データには、映像データのみが含まれてもよい。映像データは、例えば、H.264もしくはH.265等の方式を用いて生成されてもよい。また、音声データは、PCM(Pulse Code Modulation)方式等を用いて生成されてもよく、映像データ及び音声データを含んだ動画像データである撮影データは、MPEG(Moving Picture Experts Group)2-TS(Transport Stream)またはAVI(Audio Video Interleave)等を用いて生成されてもよい。
The imaging data acquisition unit 21 acquires video data generated by the camera 31 and audio data generated by the microphone 32. Data including video data and audio data may be referred to as shooting data. In other words, the shooting data acquisition unit 21 may be paraphrased as acquiring shooting data from the camera 31 and the microphone 32. Further, the shooting data may be data including at least video data. In other words, only the video data may be included in the shooting data. The video data is, for example, H.264. H.264 or H.264 It may be generated using a method such as H.265. The audio data may be generated using a PCM (Pulse Code Modulation) method or the like, and shooting data that is moving image data including video data and audio data is MPEG (Moving Picture Experts Group) 2-TS. (Transport Stream) or AVI (Audio (Video Interleave) may be used.
撮影データ取得部21は、映像データを含む撮影データをバッファメモリ24へ出力する。バッファメモリ24は、出力された撮影データを一時的に記憶する。バッファメモリ24は、制御部20内に内蔵される内蔵メモリと称されてもよい。一時的に記憶するとは、例えば、バッファメモリ24が、所定期間経過した撮影データを消去することであってもよい。もしくは、一時的に記憶するとは、撮影データ取得部21から出力されるデータを、バッファメモリ24内のデータに上書きして記憶することであってもよい。もしくは、一時的に記憶するとは、バッファメモリ24が、撮影データ取得部21から出力された撮影データを記録制御部23もしくは検出部26へ出力した場合に、出力した撮影データを消去することであってもよい。
The shooting data acquisition unit 21 outputs shooting data including video data to the buffer memory 24. The buffer memory 24 temporarily stores the output shooting data. The buffer memory 24 may be referred to as a built-in memory built in the control unit 20. Temporarily storing may mean, for example, that the buffer memory 24 erases shooting data after a predetermined period. Alternatively, temporarily storing may mean storing the data output from the captured data acquisition unit 21 by overwriting the data in the buffer memory 24. Alternatively, temporarily storing means that when the buffer memory 24 outputs the shooting data output from the shooting data acquisition unit 21 to the recording control unit 23 or the detection unit 26, the output shooting data is deleted. May be.
イベント検出部22は、センサ34から出力された情報を用いてイベント発生を検出する。例えば、加速度センサとして動作するセンサ34において検出した衝撃レベルが所定値を超えている場合に、イベント検出部22は、交通事故というイベントが発生したことを検出する。衝撃レベルが所定値を超えるとは、加速度が所定値を超えると言い換えられてもよい。イベント検出部22は、イベントの発生を検出した場合、イベントが発生したことを示す情報を記録制御部23へ出力する。イベントが発生したことを示す情報には、イベントが発生した時刻が含まれる。さらに、イベントが発生したことを示す情報には、発生したイベントの内容が含まれてもよい。
The event detection unit 22 detects the occurrence of an event using information output from the sensor 34. For example, when the impact level detected by the sensor 34 operating as an acceleration sensor exceeds a predetermined value, the event detection unit 22 detects that an event of a traffic accident has occurred. The impact level exceeding a predetermined value may be rephrased as the acceleration exceeding the predetermined value. When the event detection unit 22 detects the occurrence of an event, the event detection unit 22 outputs information indicating that the event has occurred to the recording control unit 23. The information indicating that an event has occurred includes the time at which the event occurred. Furthermore, the information indicating that an event has occurred may include the content of the event that has occurred.
検出部26は、バッファメモリ24に記憶されている撮影データの中からプライバシーに関わる映像を検出する。例えば、プライバシーに関わる映像は、人の顔もしくは車両のナンバープレート等が表示された映像であってもよい。検出部26は、人の顔を検出する顔検出部及び車両のナンバープレートを検出するナンバープレート検出部の少なくとも一方を含む。
The detecting unit 26 detects a video related to privacy from the shooting data stored in the buffer memory 24. For example, the video related to privacy may be a video on which a human face or a vehicle license plate is displayed. The detection unit 26 includes at least one of a face detection unit that detects a human face and a license plate detection unit that detects a license plate of a vehicle.
記録制御部23は、バッファメモリ24に記憶された撮影データをファイル形式として記録部33に記録する。記録制御部23は、イベント検出部22が検出したイベントに起因してバッファメモリ24に記憶された撮影データを記録部33へ記録する時は、プライバシー対策を行うことなくバッファメモリ24から取得した撮影データを記録部33へ記録する。言い換えると、記録制御部23は、バッファメモリ24から記録部33へ撮影データを移行する。記録制御部23は、イベント検出部22が検出したイベントに起因してバッファメモリ24に記憶された撮影データを記録部33へ記録する時は、バッファメモリ24から取得した撮影データをそのまま記録部33へ記録する。具体的には、記録制御部23は、バッファメモリ24に記憶された撮影データから映像データおよび音声データを含む動画像ファイルを生成して、記録部33に記録する。バッファメモリ24に記憶された撮影データに音声データが含まれない場合、記録制御部23は、映像データのみを含む動画像ファイルを生成して、記録部33に記録する。
The recording control unit 23 records the shooting data stored in the buffer memory 24 in the recording unit 33 as a file format. When recording the shooting data stored in the buffer memory 24 due to the event detected by the event detection unit 22 in the recording unit 33, the recording control unit 23 acquires the shooting acquired from the buffer memory 24 without taking privacy measures. Data is recorded in the recording unit 33. In other words, the recording control unit 23 transfers the shooting data from the buffer memory 24 to the recording unit 33. When recording the shooting data stored in the buffer memory 24 due to the event detected by the event detection unit 22 in the recording unit 33, the recording control unit 23 records the shooting data acquired from the buffer memory 24 as it is. To record. Specifically, the recording control unit 23 generates a moving image file including video data and audio data from the shooting data stored in the buffer memory 24 and records the moving image file in the recording unit 33. When the shooting data stored in the buffer memory 24 does not include audio data, the recording control unit 23 generates a moving image file including only video data and records the moving image file in the recording unit 33.
記録制御部23は、イベント検出部22が検出したイベントに起因せずにバッファメモリ24に記憶された撮影データを記録部33へ記録する時は、バッファメモリ24から取得した撮影データに対してプライバシー対策を行い、プライバシー対策を行った撮影データを記録部33へ記録する。具体的には、検出部26は、プライバシーに関わる映像の検出結果に関する情報を記録制御部23へ出力する。記録制御部23は、バッファメモリ24に記憶された撮影データにおける、検出部26において検出されたプライバシーに関わる映像データに対してプライバシー対策を行う。プライバシー対策は、例えば、検出部26において人の顔が検出された場合、検出された顔が不明瞭となるように映像データを加工することであってもよい。映像データを加工するとは、映像データを修正すると言い換えられてもよい。もしくは、プライバシー対策は、検出部26においてナンバープレートが検出された場合、検出されたナンバープレートが不明瞭となるように映像データを加工することであってもよい。
When recording the shooting data stored in the buffer memory 24 without being attributed to the event detected by the event detection unit 22 to the recording unit 33, the recording control unit 23 is privacy with respect to the shooting data acquired from the buffer memory 24. Measured data is recorded in the recording unit 33 for privacy measures. Specifically, the detection unit 26 outputs information related to the detection result of the video related to privacy to the recording control unit 23. The recording control unit 23 performs privacy countermeasures on the video data related to privacy detected by the detection unit 26 in the shooting data stored in the buffer memory 24. For example, when the detection unit 26 detects a human face, the privacy measure may be to process the video data so that the detected face becomes unclear. Processing video data may be paraphrased as correcting video data. Alternatively, the privacy measure may be to process the video data so that the detected license plate is unclear when the detection unit 26 detects the license plate.
カメラ31が、車両外のみを撮影するカメラである場合、記録制御部23において行われるプライバシー対策は、主にナンバープレートが不明瞭となるように映像データを加工することであってもよい。この場合、検出部26は、人の顔を検出せずに、車両のナンバープレートのみを検出する。もしくは、カメラ31が、車両外のみを撮影するカメラである場合、記録制御部23において行われるプライバシー対策は、人の顔及びナンバープレートが不明瞭となるように映像データを加工することであってもよい。
When the camera 31 is a camera that captures only the outside of the vehicle, the privacy measure performed in the recording control unit 23 may be mainly processing the video data so that the license plate is unclear. In this case, the detection unit 26 detects only the license plate of the vehicle without detecting a human face. Alternatively, when the camera 31 is a camera that captures only the outside of the vehicle, the privacy measure performed in the recording control unit 23 is to process the video data so that the human face and the license plate are unclear. Also good.
カメラ31が、車両外及び車両内を撮影するカメラである場合、記録制御部23において行われるプライバシー対策は、人の顔及びナンバープレートが不明瞭となるように映像データを加工することであってもよい。具体的には、記録制御部23は、車両外を撮影した撮影データに対しては、ナンバープレートが不明瞭となるように映像データを加工し、車両内を撮影した撮影データに対しては、人の顔が不明瞭となるように映像データを加工してもよい。もしくは、カメラ31が、車両外及び車両内を撮影するカメラである場合、記録制御部23は、車両外を撮影した撮影データに対して、人の顔及びナンバープレートが不明瞭となるように映像データを加工してもよい。
When the camera 31 is a camera that captures the outside and inside of the vehicle, the privacy measure performed in the recording control unit 23 is to process the video data so that the human face and the license plate are unclear. Also good. Specifically, the recording control unit 23 processes the video data so that the license plate is unclear for the shooting data shot outside the vehicle, and for the shooting data shot inside the vehicle, The video data may be processed so that the human face is unclear. Alternatively, when the camera 31 is a camera that captures the outside of the vehicle and the inside of the vehicle, the recording control unit 23 displays an image so that the human face and the license plate are unclear with respect to the shooting data that is captured outside the vehicle. Data may be processed.
記録制御部23は、映像データにおいて認識される人の顔の大きさが所定値以上である場合に、プライバシー対策として、人の顔が不明瞭となるように映像データを加工してもよい。人の顔の大きさに応じてプライバシー対策の対象を決定することによって、例えば、車両から所定の距離以上離れた人の顔に関しては、プライバシー対策の対象外とすることができる。映像データにおいては、カメラから離れた位置において撮影された人の顔ほど小さくなる。そのため、人の顔を識別することができないほど小さい顔に関しては、プライバシー対策の対象外としても問題無い。また、車両内を撮影した撮影データに関しても、所定値を下回る顔の大きさの人は、車両内の同乗者ではなく、車両の窓から見える車両外の通行者である可能性もある。つまり、車両内を撮影した撮影データに関して、人の顔の大きさに応じて、プライバシー対策を行うか否かを決定することによって、車両内の同乗者のみをプライバシー対策の対象と決定することもできる。人の顔の大きさの所定値は、プライバシー対策を実施する範囲に応じて決定される。プライバシー対策を実施する範囲は、例えば、車両から数メートル以内の範囲等と決定されてもよい。
The recording control unit 23 may process the video data so that the human face is unclear as a privacy measure when the size of the human face recognized in the video data is greater than or equal to a predetermined value. By determining the privacy countermeasure target according to the size of the person's face, for example, the face of a person away from the vehicle by a predetermined distance or more can be excluded from the privacy countermeasure target. In the video data, the face of a person photographed at a position away from the camera becomes smaller. Therefore, a face that is so small that a human face cannot be identified can be excluded from the privacy measures. In addition, regarding image data obtained by photographing the inside of a vehicle, a person whose face size is smaller than a predetermined value may not be a passenger inside the vehicle but a passer-by outside the vehicle that can be seen from the window of the vehicle. In other words, by determining whether or not to take privacy measures according to the size of a person's face with respect to shooting data taken inside the vehicle, only passengers in the vehicle can be determined as privacy measures. it can. The predetermined value of the size of the person's face is determined according to the range where privacy measures are implemented. The range in which the privacy measure is implemented may be determined as a range within a few meters from the vehicle, for example.
また、記録制御部23は、映像データにおいて認識されるナンバープレートのナンバーの数に応じて、プライバシー対策を行うか否かを判定してもよい。例えば、ナンバープレートのナンバーが4桁である場合に、映像データにおいて認識されるナンバーが、3桁以上である場合、ナンバープレートが不明瞭となるように映像データを加工してもよい。記録制御部23は、ナンバープレートの数に応じて、プライバシー対策を行うか否かを判定する以外にも、ナンバープレートにおいて示される他の情報を用いて、プライバシー対策を行うか否かを判定してもよい。
Further, the recording control unit 23 may determine whether or not to take privacy measures according to the number of license plate numbers recognized in the video data. For example, when the number of the license plate is 4 digits and the number recognized in the video data is 3 digits or more, the video data may be processed so that the license plate is unclear. The recording control unit 23 determines whether or not to take privacy countermeasures by using other information shown in the license plate in addition to determining whether or not to take privacy countermeasures according to the number of license plates. May be.
映像データにおいて認識される人の顔の大きさもしくはナンバープレートのナンバーの数等に応じて、プライバシー対策の対象を限定することによって、イベントが発生していない期間における記録制御部23の処理負担を軽減させることができる。
The processing load of the recording control unit 23 during a period in which no event occurs is limited by limiting the privacy countermeasure target according to the size of the face of the person recognized in the video data or the number of license plate numbers. It can be reduced.
記録制御部23は、撮影データを記録部33へ記録する場合、イベントに起因した撮影データ、つまりプライバシー対策が行われていない撮影データを含む撮影データを上書き禁止のデータとして記録部33へ記録してもよい。例えば、記録制御部23は、データの上書きを禁止する記録部33内のメモリ領域のアドレスを指定して、撮影データを記録部33へ記録してもよい。もしくは、記録制御部23は、撮影データのヘッダもしくはペイロードに上書き禁止を示すフラグ情報等を設定してもよい。
When recording the shooting data in the recording unit 33, the recording control unit 23 records the shooting data resulting from the event, that is, shooting data including shooting data for which privacy measures are not taken, in the recording unit 33 as overwriting-prohibited data. May be. For example, the recording control unit 23 may specify the address of the memory area in the recording unit 33 that prohibits overwriting of data, and record the photographing data in the recording unit 33. Alternatively, the recording control unit 23 may set flag information indicating prohibition of overwriting in the header or payload of the photographic data.
また、記録制御部23は、イベントに起因しない撮影データ、つまりプライバシー対策が行われた撮影データを含む撮影データを記録部33へ記録する場合、撮影データを上書き可能のデータとして記録部33へ記録してもよい。例えば、記録制御部23は、記録部33のデータの上書きを可能とするメモリ領域のアドレスを指定して、撮影データを記録部33へ記録してもよい。もしくは、記録制御部23は、撮影データのヘッダもしくはペイロードに上書き可能を示すフラグ情報を設定してもよい。
In addition, when the recording control unit 23 records shooting data that does not result from an event, that is, shooting data including shooting data for which privacy measures have been taken, to the recording unit 33, the shooting data is recorded in the recording unit 33 as data that can be overwritten. May be. For example, the recording control unit 23 may record the shooting data in the recording unit 33 by designating an address of a memory area in which data in the recording unit 33 can be overwritten. Alternatively, the recording control unit 23 may set flag information indicating that overwriting is possible in the header or payload of the imaging data.
記録部33は、記録制御部23から出力されたデータ、言い換えると記録制御部23を介してバッファメモリ24から移行されたデータを記録する。
The recording unit 33 records the data output from the recording control unit 23, in other words, the data transferred from the buffer memory 24 via the recording control unit 23.
再生制御部25は、記録部33に記録されている撮影データを取得し、取得した撮影データに基づく映像データを表示部35へ出力し、取得した撮影データに基づく音声データをスピーカ36等へ出力する。
The playback control unit 25 acquires the shooting data recorded in the recording unit 33, outputs video data based on the acquired shooting data to the display unit 35, and outputs audio data based on the acquired shooting data to the speaker 36 and the like. To do.
図1においては、記録装置10が、再生制御部25、表示部35、及びスピーカ36を含む構成を示しているが、記録装置10とは異なる再生装置等が、再生制御部25、表示部35、及びスピーカ36を含んでもよい。言い換えると、記録装置10は、再生制御部25、表示部35、及びスピーカ36を含まなくてもよい。つまり、再生制御部25、表示部35、及びスピーカ36を含む再生装置等が、記録装置10の記録部33に記録されたデータを再生してもよい。例えば、再生装置等は、光ディスクもしくはカード型記録媒体等の持ち運び可能な記録媒体に記録されたデータを再生する装置であってもよい。記録部33に記録されたデータは、持ち運び可能な記録媒体に移行されてもよい。
1 shows a configuration in which the recording device 10 includes a reproduction control unit 25, a display unit 35, and a speaker 36. However, a reproduction device or the like different from the recording device 10 includes a reproduction control unit 25 and a display unit 35. And a speaker 36 may be included. In other words, the recording apparatus 10 may not include the reproduction control unit 25, the display unit 35, and the speaker 36. That is, a playback device including the playback control unit 25, the display unit 35, and the speaker 36 may play back the data recorded in the recording unit 33 of the recording device 10. For example, the playback device or the like may be a device that plays back data recorded on a portable recording medium such as an optical disk or a card-type recording medium. Data recorded in the recording unit 33 may be transferred to a portable recording medium.
ここで、図2を用いて、記録部33に記録されるデータと、バッファメモリ24に記録されるデータとの関係について説明する。図2に示される横軸は、時間の経過を示している。D-4~D+2のそれぞれは、所定期間の間に撮影された撮影データを示している。図2においては、D-4が、最も古く撮影された撮影データであり、D+2が最も新しく撮影された撮影データである。所定期間とは、例えば、数秒、数十秒、数分等であってもよい。
Here, the relationship between the data recorded in the recording unit 33 and the data recorded in the buffer memory 24 will be described with reference to FIG. The horizontal axis shown in FIG. 2 indicates the passage of time. Each of D-4 to D + 2 represents shooting data shot during a predetermined period. In FIG. 2, D-4 is the oldest photographed data, and D + 2 is the latest photographed data. For example, the predetermined period may be several seconds, several tens of seconds, several minutes, or the like.
撮影データ取得部21が取得した撮影データは、すぐにバッファメモリ24へ出力される。そのため、図2においては、撮影データ取得部21において取得した撮影データが、そのままバッファメモリ24に記憶されていることが示されている。言い換えると、図2においては、撮影データ取得部21が撮影データを取得したタイミングと、バッファメモリ24に撮影データが記憶されるタイミングとが実質的に一致していることが示されている。実質的に一致しているとは、撮影データ取得部21が撮影データを取得したタイミングと、バッファメモリ24に撮影データが記憶されるタイミングとが完全に一致しない場合も含まれる。例えば、実質的に一致しているとは、バッファメモリ24に撮影データが記憶されるタイミングが、撮影データ取得部21が撮影データを取得したタイミングよりも後にずれることも含まれる。一方、記録部33に記録される撮影データは、一時的にバッファメモリ24に記憶された後に、記録制御部23によって記録部33に記録される。そのため、撮影データ取得部21が取得した撮影データが、バッファメモリ24に記憶されるタイミングと、記録部33に記録されるタイミングとは異なる。具体的には、撮影データが記録部33に記録されるタイミングは、撮影データがバッファメモリ24に記憶されるタイミングよりも遅い。
The shooting data acquired by the shooting data acquisition unit 21 is immediately output to the buffer memory 24. For this reason, FIG. 2 shows that the shooting data acquired by the shooting data acquisition unit 21 is stored in the buffer memory 24 as it is. In other words, FIG. 2 shows that the timing at which the imaging data acquisition unit 21 acquires the imaging data and the timing at which the imaging data is stored in the buffer memory 24 substantially match. The term “substantially match” includes the case where the timing at which the shooting data acquisition unit 21 acquires the shooting data does not completely match the timing at which the shooting data is stored in the buffer memory 24. For example, the term “substantially match” includes that the timing at which shooting data is stored in the buffer memory 24 is shifted later than the timing at which the shooting data acquisition unit 21 acquires shooting data. On the other hand, the photographing data recorded in the recording unit 33 is temporarily stored in the buffer memory 24 and then recorded in the recording unit 33 by the recording control unit 23. Therefore, the timing at which the shooting data acquired by the shooting data acquisition unit 21 is stored in the buffer memory 24 is different from the timing at which it is recorded in the recording unit 33. Specifically, the timing at which shooting data is recorded in the recording unit 33 is later than the timing at which shooting data is stored in the buffer memory 24.
t1~t6は、時刻を示す。記録制御部23は、時刻t1~t6に過去の所定期間にイベントが発生したか否かを判定する。例えば、記録制御部23は、時刻t2において、時刻t1から時刻t2までの間に、イベントが発生したか否かを判定する。記録制御部23は、他の時刻においても同様にイベントが発生したか否かを判定する。図2においては、記録制御部23は、時刻t1~t3及び時刻t5においては、イベントが発生していないと判定する。また、記録制御部23は、時刻t4においては、時刻t3と時刻t4との間である時刻t6にイベントが発生したと判定する。
T1 to t6 indicate time. The recording control unit 23 determines whether an event has occurred in the past predetermined period from time t1 to t6. For example, the recording control unit 23 determines whether an event has occurred between time t1 and time t2 at time t2. The recording control unit 23 determines whether or not an event has occurred at other times as well. In FIG. 2, the recording control unit 23 determines that no event has occurred at times t1 to t3 and time t5. In addition, at time t4, the recording control unit 23 determines that an event has occurred at time t6, which is between time t3 and time t4.
記録制御部23は、例えば、時刻t2において、時刻t1から時刻t2までの間に、イベントが発生していないと判定した場合、バッファメモリ24に記憶されている撮影データD-2に含まれる映像データに対してプライバシー対策を行う。記録制御部23は、人の顔及び車両のナンバープレートの少なくとも一方が不明瞭となった映像データを含む撮影データをファイル化して記録部33へ記録する。一方、記録制御部23は、時刻t4において、時刻t3から時刻t4までの間の時刻t6にイベントが発生したと判定する。この場合、記録制御部23は、時刻t6において撮影データ取得部21において取得されたデータDに対してプライバシー対策を行うことなく、バッファメモリ24に記憶されているデータDをそのままファイル化して記録部33へ記録する。
For example, when the recording control unit 23 determines at time t2 that no event has occurred between time t1 and time t2, the video included in the shooting data D-2 stored in the buffer memory 24 Take privacy measures on data. The recording control unit 23 records shooting data including video data including video data in which at least one of a human face and a license plate of a vehicle is obscured into a recording unit 33. On the other hand, the recording control unit 23 determines that an event has occurred at time t6 between time t3 and time t4 at time t4. In this case, the recording control unit 23 converts the data D stored in the buffer memory 24 into a file as it is without taking a privacy measure for the data D acquired by the photographic data acquisition unit 21 at time t6. Record to 33.
図2においては、バッファメモリ24への記憶が完了された撮影データが、即座に記録部33へ記録されることを示しているが、バッファメモリ24へ記憶されている撮影データを記録部33へ記録するタイミングは、図2に制限されない。例えば、記録制御部23は、バッファメモリ24へ記憶している最中の撮影データを取得し、取得した撮影データを記録部33へ記録してもよい。もしくは、記録制御部23は、バッファメモリ24への撮影データの記憶が完了した場合、撮影データの記憶が完了した時点から所定期間経過後に、その撮影データを記録部33へ記録してもよい。ここで、撮影データとは、図2に示すD-4~D+2のいずれかを意図している。
Although FIG. 2 shows that shooting data that has been stored in the buffer memory 24 is immediately recorded in the recording unit 33, the shooting data stored in the buffer memory 24 is stored in the recording unit 33. The recording timing is not limited to FIG. For example, the recording control unit 23 may acquire the shooting data being stored in the buffer memory 24 and record the acquired shooting data in the recording unit 33. Alternatively, the recording control unit 23 may record the shooting data in the recording unit 33 after a predetermined period has elapsed from the time when the storage of the shooting data is completed when the shooting data is stored in the buffer memory 24. Here, the photographing data is intended to be any one of D-4 to D + 2 shown in FIG.
また、図2においては、記録制御部23は、イベントが発生した時刻を含む期間に撮影データ取得部21において取得された撮影データのみに対してプライバシー対策を行わずに記録部33へ記録することを示している。記録制御部23は、これに制限されず、例えば、イベントが発生した時刻を含む期間に撮影データ取得部21において取得された撮影データに加えて、イベントが発生した時刻を含む期間の前の期間に撮影データ取得部21において取得された撮影データに対してもプライバシー対策を行わずに記録部33へ記録してもよい。例えば、記録制御部23は、時刻t6において、撮影データ取得部21に取得されたデータDに加えて、データD-1に対してもプライバシー対策を行わずに記録部33へ記録してもよい。
In FIG. 2, the recording control unit 23 records, in the recording unit 33, only the shooting data acquired by the shooting data acquisition unit 21 during the period including the time when the event occurs without performing privacy measures. Is shown. The recording control unit 23 is not limited to this. For example, in addition to the shooting data acquired by the shooting data acquisition unit 21 during the period including the time when the event occurred, the period before the period including the time when the event occurred In addition, the shooting data acquired by the shooting data acquisition unit 21 may be recorded in the recording unit 33 without taking privacy measures. For example, the recording control unit 23 may record the data D-1 in the recording unit 33 without taking privacy measures in addition to the data D acquired by the imaging data acquisition unit 21 at time t6. .
また、記録制御部23は、イベントが発生していないと判定した場合においても、バッファメモリ24に記憶されている最新の期間に取得された撮影データに加えて、最新の期間よりも前の期間に取得された撮影データに対してもプライバシー対策を行い記録部33へ記録してもよい。
Even when the recording control unit 23 determines that an event has not occurred, in addition to the shooting data acquired in the latest period stored in the buffer memory 24, the period before the latest period Also, the captured data acquired in the above may be recorded in the recording unit 33 by taking a privacy measure.
図2においては、記録部33にデータD-4~D-1を記録する期間、及び、データD+1を記録する期間を、プライバシー対策実施期間とし、記録部33にデータDを記録する期間をプライバシー対策不実施期間としている。
In FIG. 2, the period for recording data D-4 to D-1 and the period for recording data D + 1 in the recording unit 33 are the privacy measure implementation period, and the period for recording the data D in the recording unit 33 is privacy. The measure is not implemented.
続いて、図3を用いて実施の形態1にかかる撮影データの記録処理の流れについて説明する。はじめに、撮影データ取得部21は、少なくとも映像データを含む撮影データをバッファメモリ24へ出力し、バッファメモリ24は、撮影データの記憶を開始する(S11)。次に、記録制御部23は、バッファメモリ24に記憶されている撮影データの記録部33への記録を開始するにあたり、イベントが発生したか否かを判定する(S12)。具体的には、記録制御部23は、移行する撮影データの撮影期間にイベントが発生したか否かを判定する。例えば、記録制御部23は、イベント検出部22において、移行する撮影データの撮影期間にイベントの発生が検出されたか否かを判定する。
Subsequently, a flow of recording processing of shooting data according to the first embodiment will be described with reference to FIG. First, the shooting data acquisition unit 21 outputs shooting data including at least video data to the buffer memory 24, and the buffer memory 24 starts storing shooting data (S11). Next, the recording control unit 23 determines whether or not an event has occurred when starting to record the shooting data stored in the buffer memory 24 in the recording unit 33 (S12). Specifically, the recording control unit 23 determines whether an event has occurred during the shooting period of the shooting data to be transferred. For example, the recording control unit 23 determines whether the event detection unit 22 detects the occurrence of an event during the shooting period of the shooting data to be transferred.
記録制御部23は、イベントが発生したと判定した場合、プライバシー対策を行うことなく、撮影期間にイベントが発生したタイミングを含む撮影データを記録部33へ記録する(S13)。記録制御部23は、プライバシー対策を行うことなくバッファメモリ24に記憶されている撮影データをファイル化して、撮影データを記録部33へ記録する。
When it is determined that the event has occurred, the recording control unit 23 records the shooting data including the timing at which the event has occurred during the shooting period in the recording unit 33 without taking privacy measures (S13). The recording control unit 23 converts the shooting data stored in the buffer memory 24 into a file without taking a privacy measure, and records the shooting data in the recording unit 33.
記録制御部23は、イベントが発生していないと判定した場合、イベントが発生していない期間に撮影された撮影データに対してプライバシー対策を行う。記録制御部23は、人の顔及び車両のナンバープレートの少なくとも一方が不明瞭となった映像データを含む撮影データを記録部33へ記録する(S14)。記録制御部23は、バッファメモリ24に記憶されている撮影データに対してプライバシー対策を行い、プライバシー対策を行った撮影データをファイル化し、撮影データを記録部33へ記録する。
When the recording control unit 23 determines that an event has not occurred, the recording control unit 23 performs privacy countermeasures on the captured data captured during a period in which no event has occurred. The recording control unit 23 records photographing data including video data in which at least one of the human face and the vehicle license plate is unclear in the recording unit 33 (S14). The recording control unit 23 performs privacy countermeasures on the shooting data stored in the buffer memory 24, creates a file of the shooting data on which privacy measures have been taken, and records the shooting data in the recording unit 33.
記録制御部23は、ステップS13もしくはS14においてバッファメモリ24内に記憶されている撮影データを記録部33へ記録した後に、バッファメモリ24内に記録部33へ記録していない撮影データが存在するか否かを判定する(S15)。
The recording control unit 23 records the shooting data stored in the buffer memory 24 in step S13 or S14 in the recording unit 33, and then there is shooting data not recorded in the recording unit 33 in the buffer memory 24. It is determined whether or not (S15).
記録制御部23は、バッファメモリ24内に記録部33へ記録していない撮影データが存在しないと判定した場合、処理を終了する。バッファメモリ24内に記録部33へ記録していない撮影データが存在しない場合とは、例えば、運転者が撮影を停止する操作を実施した場合、もしくは、エンジンが停止し撮影が停止された場合等がある。
When the recording control unit 23 determines that there is no shooting data not recorded in the recording unit 33 in the buffer memory 24, the recording control unit 23 ends the processing. The case where there is no shooting data that is not recorded in the recording unit 33 in the buffer memory 24 is, for example, when the driver performs an operation to stop shooting, or when the shooting is stopped because the engine is stopped. There is.
記録制御部23は、バッファメモリ24内に記録部33へ記録していない撮影データが存在すると判定した場合、ステップS12以降の処理を繰り返し実行する。
When the recording control unit 23 determines that there is shooting data that is not recorded in the recording unit 33 in the buffer memory 24, the recording control unit 23 repeatedly executes the processing from step S12.
以上説明したように、実施の形態1にかかる記録装置10は、イベントが発生したタイミングを撮影期間に含む撮影データに関しては、プライバシー対策が行われていない映像データを記録部33へ記録することができる。また、記録装置10は、イベントが発生していない期間に撮影された撮影データに関しては、プライバシー対策が行われ、人の顔及び車両のナンバープレートの少なくとも一方が不明瞭となった映像データを記録部33へ記録することができる。これにより、記録装置10は、交通事故等のイベントが発生した際の撮影データに関しては、人の顔や車両のナンバープレートが映っている場合であってもそれらが判別可能な未加工の撮影データが記録されているため事故原因の究明等に役立てることができる。一方、記録装置10は、イベントが発生していない期間の撮影データに関しては、人の顔及び車両のナンバープレートの少なくとも一方を不明瞭とすることによって、車両内外の撮影対象のプライバシーを保護することができる。
As described above, the recording apparatus 10 according to the first embodiment can record video data for which privacy measures are not taken in the recording unit 33 with respect to shooting data including the timing at which an event occurs in the shooting period. it can. Further, the recording device 10 records video data in which at least one of the human face and the vehicle license plate is obscured with respect to the captured data captured during a period in which no event occurs. It can be recorded in the section 33. As a result, the recording device 10 is able to determine the shooting data when an event such as a traffic accident occurs, even if the human face or the license plate of the vehicle is reflected, and the raw shooting data that can be identified. Can be used to investigate the cause of the accident. On the other hand, the recording device 10 protects the privacy of the subject to be photographed inside and outside the vehicle by making at least one of the human face and the license plate of the vehicle unclear about the shooting data during a period in which no event occurs. Can do.
(実施の形態2)
続いて、図4を用いて実施の形態2にかかる記録装置40の構成例について説明する。記録装置40は、図1の記録装置10における制御部20の代わりに制御部41を有する。また、制御部41は、図1の制御部20に音量レベル取得部42が追加された構成である。記録装置40について、記録装置10と同じ構成については同じ符号を付しており、詳細な説明を省略する。以下に、記録装置40について、記録装置10と異なる構成に関して主に説明する。記録装置40も記録装置10と同様に、制御部41によって実現される構成要素を備える構成としてもよい。具体的には、記録装置40は、撮影データ取得部21、イベント検出部22、記録制御部23、検出部26および音量レベル取得部42を備える。 (Embodiment 2)
Next, a configuration example of therecording apparatus 40 according to the second embodiment will be described with reference to FIG. The recording device 40 includes a control unit 41 instead of the control unit 20 in the recording device 10 of FIG. The control unit 41 has a configuration in which a volume level acquisition unit 42 is added to the control unit 20 of FIG. About the recording device 40, the same code | symbol is attached | subjected about the same structure as the recording device 10, and detailed description is abbreviate | omitted. In the following, the recording device 40 will be mainly described with respect to a configuration different from that of the recording device 10. Similarly to the recording apparatus 10, the recording apparatus 40 may include a component realized by the control unit 41. Specifically, the recording device 40 includes an imaging data acquisition unit 21, an event detection unit 22, a recording control unit 23, a detection unit 26, and a volume level acquisition unit 42.
続いて、図4を用いて実施の形態2にかかる記録装置40の構成例について説明する。記録装置40は、図1の記録装置10における制御部20の代わりに制御部41を有する。また、制御部41は、図1の制御部20に音量レベル取得部42が追加された構成である。記録装置40について、記録装置10と同じ構成については同じ符号を付しており、詳細な説明を省略する。以下に、記録装置40について、記録装置10と異なる構成に関して主に説明する。記録装置40も記録装置10と同様に、制御部41によって実現される構成要素を備える構成としてもよい。具体的には、記録装置40は、撮影データ取得部21、イベント検出部22、記録制御部23、検出部26および音量レベル取得部42を備える。 (Embodiment 2)
Next, a configuration example of the
音量レベル取得部42は、マイクロフォン32が生成した音声データから音量レベルに関する情報を取得する。音量レベル取得部42は、撮影データ取得部21が取得した音声データから音量レベルに関する情報を取得してもよい。音量レベルは、例えば、音声のボリュームを示す情報であってもよい。音量レベル取得部42は、音量レベルに関する情報を記録制御部23へ出力する。具体的には、音量レベルに関する情報には、音声データの識別情報が含まれてもよい。
The volume level acquisition unit 42 acquires information about the volume level from the audio data generated by the microphone 32. The volume level acquisition unit 42 may acquire information related to the volume level from the audio data acquired by the imaging data acquisition unit 21. The volume level may be information indicating the volume of audio, for example. The volume level acquisition unit 42 outputs information related to the volume level to the recording control unit 23. Specifically, the information regarding the sound volume level may include identification information of the audio data.
図4においては、音量レベル取得部42が、マイクロフォン32と記録制御部23との間に配置されることを示しているが、音量レベル取得部42は、撮影データ取得部21と記録制御部23との間に配置されてもよい。
4 shows that the volume level acquisition unit 42 is disposed between the microphone 32 and the recording control unit 23. However, the volume level acquisition unit 42 includes the shooting data acquisition unit 21 and the recording control unit 23. Between the two.
記録制御部23は、イベント検出部22が検出したイベントに起因せずにバッファメモリ24に記憶された撮影データを記録部33へ記録する時は、音声データに関する音量レベルに応じて、プライバシー対策を行うか否かを決定する。例えば、通常会話レベルの音量と、通常会話レベルを超えた大声との間に音量レベルの閾値1を設ける。つまり、閾値1は、通常会話レベルとそれ以上の音量レベルとを識別するために用いられる。通常会話レベルを超えた大声とは、例えば人間の叫び声もしくは怒鳴り声等であってもよい。
When recording the shooting data stored in the buffer memory 24 without being caused by the event detected by the event detection unit 22 in the recording unit 33, the recording control unit 23 takes privacy measures according to the volume level related to the audio data. Decide whether to do it. For example, a threshold value 1 of the sound volume level is provided between the sound volume of the normal conversation level and the loud voice exceeding the normal conversation level. That is, the threshold value 1 is used to distinguish between a normal conversation level and a volume level higher than that. The loud voice exceeding the normal conversation level may be, for example, a human screaming or yelling voice.
記録制御部23は、音量レベルが閾値1未満の場合、プライバシー対策を行った映像データを記録部33へ記録する。また、記録制御部23は、音声レベルが閾値1を超えている場合、イベント検出部22においてイベントの発生が検出されていない場合であっても、プライバシー対策を行うことなく、撮影データを記録部33へ記録する。
When the volume level is less than the threshold value 1, the recording control unit 23 records video data on which privacy measures have been taken in the recording unit 33. Further, the recording control unit 23 records the captured data without taking privacy measures even when the sound level exceeds the threshold 1 and the event detection unit 22 does not detect the occurrence of an event. Record to 33.
記録制御部23が閾値1を用いてプライバシー対策を行うか否かを判定することによって、撮影対象のプライバシーを保護することができる。さらに、センサ34においてイベントは検出されないが、通常会話レベルを超えた大声が検出されたことによって、車内において何らかの異常が発生していると想定される場合等に、プライバシー対策が行われていない撮影データを記録部33に記録することができる。
When the recording control unit 23 determines whether or not to take a privacy measure using the threshold value 1, the privacy of the shooting target can be protected. Furthermore, no event is detected by the sensor 34, but no privacy measures are taken when it is assumed that some abnormality has occurred in the vehicle due to the detection of a loud voice exceeding the normal conversation level. Data can be recorded in the recording unit 33.
続いて、図5を用いて実施の形態2にかかる撮影データの記録処理の流れについて説明する。ステップS21~S25は、図3のステップS11~S15と同様であるため詳細な説明を省略する。
Subsequently, a flow of recording processing of shooting data according to the second embodiment will be described with reference to FIG. Steps S21 to S25 are the same as steps S11 to S15 in FIG.
記録制御部23は、ステップS22においてイベントが発生していないと判定した場合、さらに、撮影データに含まれる音声データの音量レベルが所定値、例えば閾値1未満であるか否かを判定する(S26)。記録制御部23は、音量レベルが閾値1を超えていると判定した場合、バッファメモリ24に記憶されている撮影データに対してプライバシー対策を行うことなく、撮影データを記録部33へ記録する(S23)。記録制御部23は、音量レベルが閾値1未満であると判定した場合、バッファメモリ24に記憶されている撮影データに対してプライバシー対策を行い、プライバシー対策が行われた撮影データを記録部33へ記録する(S24)。
If the recording control unit 23 determines in step S22 that no event has occurred, the recording control unit 23 further determines whether or not the volume level of the audio data included in the captured data is less than a predetermined value, for example, a threshold value 1 (S26). ). When the recording control unit 23 determines that the volume level exceeds the threshold value 1, the recording control unit 23 records the shooting data in the recording unit 33 without taking a privacy measure for the shooting data stored in the buffer memory 24 ( S23). When the recording control unit 23 determines that the volume level is less than the threshold value 1, the recording control unit 23 performs privacy measures on the shooting data stored in the buffer memory 24, and the shooting data on which privacy measures have been taken is sent to the recording unit 33. Record (S24).
以上説明したように、実施の形態2にかかる記録装置40を用いることによって、音量レベルに応じて撮影データに対してプライバシー対策を行うか否かを判定することができる。これにより、記録装置40は、イベント検出部22においてはイベントを検出することができない場合であっても、車内で異常が発生したと推定してプライバシー対策が行われていない撮影データを記録部33へ記録することができる。
As described above, by using the recording device 40 according to the second embodiment, it is possible to determine whether or not to take a privacy measure for the photographic data according to the volume level. As a result, even if the event detection unit 22 cannot detect the event, the recording device 40 presumes that an abnormality has occurred in the vehicle and does not take privacy measures. Can be recorded.

The communication unit 37 transmits or receives data to / from the external recording device 5. Specifically, the transmission unit 38 transmits data to the external recording device 5, and the reception unit 39 receives data transmitted from the external recording device 5. The communication unit 37 may be connected to a network by using, for example, a wireless LAN (Local Area Network) communication method. Alternatively, the communication unit 37 may be connected to a network using a wireless communication standard such as LTE (Long Term Evolution). For example, the transmission unit 38 performs modulation processing or the like on the photographing data output from the control unit 51, and transmits the wireless data generated as a result to the external recording device 5. In addition, for example, the reception unit 39 demodulates the wireless data transmitted from the external recording device 5 and outputs the shooting data generated as a result to the control unit 51. Alternatively, the modulation process for the photographing data and the demodulation process for the radio data may be performed in the transmission control unit 28 and the reception control unit 29 in the control unit 51.
記録制御部23は、バッファメモリ24に記憶された撮影データをファイル形式として送信制御部28へ出力する。送信制御部28は、撮影データを、送信部38を介して外部記録装置5へ送信する。記録制御部23は、イベント検出部22が検出したイベントに起因してバッファメモリ24に記憶された撮影データを送信制御部28へ出力する時は、プライバシー対策を行うことなくバッファメモリ24から取得した撮影データを送信制御部28へ出力する。言い換えると、記録制御部23は、バッファメモリ24から取得した撮影データを、送信制御部28及び送信部38を介して外部記録装置5へ移行する。さらに言い換えると、記録制御部23は、バッファメモリ24から取得した撮影データを、外部記録装置5へ記録する。記録制御部23は、イベント検出部22が検出したイベントに起因してバッファメモリ24に記憶された撮影データを送信制御部28へ出力する時は、バッファメモリ24から取得した撮影データをそのまま送信制御部28へ出力する。具体的には、記録制御部23は、バッファメモリ24に記憶された撮影データから映像データおよび音声データを含む動画像ファイルを生成して、送信制御部28へ出力する。バッファメモリ24に記憶された撮影データに音声データが含まれない場合、記録制御部23は、映像データのみを含む動画像ファイルを生成して、送信制御部28へ出力する。
The recording control unit 23 outputs the shooting data stored in the buffer memory 24 to the transmission control unit 28 as a file format. The transmission control unit 28 transmits the photographing data to the external recording device 5 via the transmission unit 38. The recording control unit 23 acquires the captured data stored in the buffer memory 24 due to the event detected by the event detection unit 22 to the transmission control unit 28 from the buffer memory 24 without taking privacy measures.

In other words, the recording control unit 23 records the shooting data acquired from the buffer memory 24 in the external recording device 5. When the recording control unit 23 outputs the shooting data stored in the buffer memory 24 due to the event detected by the event detection unit 22 to the transmission control unit 28, the recording control unit 23 performs transmission control on the shooting data acquired from the buffer memory 24 as it is.

記録制御部23は、イベント検出部22が検出したイベントに起因せずにバッファメモリ24に記憶された撮影データを送信制御部28へ出力する時は、バッファメモリ24から取得した撮影データに対してプライバシー対策を行い、プライバシー対策を行った撮影データを送信制御部28へ出力する。具体的には、検出部26は、プライバシーに関わる映像の検出結果に関する情報を記録制御部23へ出力する。記録制御部23は、バッファメモリ24に記憶された撮影データにおける、検出部26において検出されたプライバシーに関わる映像データに対してプライバシー対策を行う。プライバシー対策は、例えば、検出部26において人の顔が検出された場合、検出された顔が不明瞭となるように映像データを加工することであってもよい。映像データを加工するとは、映像データを修正すると言い換えられてもよい。もしくは、プライバシー対策は、検出部26においてナンバープレートが検出された場合、検出されたナンバープレートが不明瞭となるように映像データを加工することであってもよい。
When the recording control unit 23 outputs the shooting data stored in the buffer memory 24 without being attributed to the event detected by the event detection unit 22 to the transmission control unit 28, the recording control unit 23 performs processing on the shooting data acquired from the buffer memory 24. The privacy measures are taken, and the photographing data for which the privacy measures are taken is output to the transmission control unit. Specifically, the detection unit 26 outputs information related to the detection result of the video related to privacy to the recording control unit 23. The recording control unit 23 performs privacy countermeasures on the video data related to privacy detected by the detection unit 26 in the shooting data stored in the buffer memory 24. For example, when the detection unit 26 detects a human face, the privacy measure may be to process the video data so that the detected face becomes unclear. Processing video data may be paraphrased as correcting video data. Alternatively, the privacy measure may be to process the video data so that the detected license plate is unclear when the detection unit 26 detects the license plate.
記録制御部23は、撮影データを送信制御部28へ出力する場合、イベントに起因した撮影データ、つまりプライバシー対策が行われていない撮影データを含む撮影データを上書き禁止のデータとして送信制御部28へ出力してもよい。例えば、記録制御部23は、データの上書きを禁止する外部記録装置5内のメモリ領域のアドレスを指定して、撮影データを送信制御部28へ出力してもよい。もしくは、記録制御部23は、撮影データのヘッダもしくはペイロードに上書き禁止を示すフラグ情報等を設定してもよい。
When outputting the shooting data to the transmission control unit 28, the recording control unit 23 sets the shooting data caused by the event, that is, shooting data including shooting data for which privacy measures are not taken, to the transmission control unit 28 as overwriting prohibition data. It may be output. For example, the recording control unit 23 may specify the address of the memory area in the external recording device 5 that prohibits overwriting of data, and output the photographing data to the transmission control unit 28. Alternatively, the recording control unit 23 may set flag information indicating prohibition of overwriting in the header or payload of the photographic data.
また、記録制御部23は、イベントに起因しない撮影データ、つまりプライバシー対策が行われた撮影データを含む撮影データを送信制御部28へ出力する場合、撮影データを上書き可能のデータとして送信制御部28へ出力してもよい。例えば、記録制御部23は、外部記録装置5のデータの上書きを可能とするメモリ領域のアドレスを指定して、撮影データを送信制御部28へ出力してもよい。もしくは、記録制御部23は、撮影データのヘッダもしくはペイロードに上書き可能を示すフラグ情報を設定してもよい。
When the recording control unit 23 outputs to the transmission control unit 28 shooting data that does not result from an event, that is, shooting data including shooting data for which privacy measures have been taken, the transmission control unit 28 sets the shooting data as data that can be overwritten. May be output. For example, the recording control unit 23 may specify an address of a memory area where data of the external recording device 5 can be overwritten, and output the photographing data to the transmission control unit 28. Alternatively, the recording control unit 23 may set flag information indicating that overwriting is possible in the header or payload of the imaging data.
再生制御部25は、外部記録装置5に記録されている撮影データを取得し、取得した撮影データに基づく映像データを表示部35へ出力し、取得した撮影データに基づく音声データをスピーカ36等へ出力する。受信制御部29は、受信部39から出力された撮影データを再生制御部25へ出力する。つまり、再生制御部25は、受信部39及び受信制御部29を介して外部記録装置5から送信された撮影データを受信する。
The reproduction control unit 25 acquires shooting data recorded in the external recording device 5, outputs video data based on the acquired shooting data to the display unit 35, and outputs audio data based on the acquired shooting data to the speaker 36 and the like. Output. The reception control unit 29 outputs the shooting data output from the reception unit 39 to the reproduction control unit 25. That is, the reproduction control unit 25 receives the shooting data transmitted from the external recording device 5 via the reception unit 39 and the reception control unit 29.
図6においては、記録装置50が、再生制御部25、受信制御部29、表示部35、及びスピーカ36を含む構成を示しているが、記録装置50とは異なる再生装置等が、再生制御部25、受信制御部29、表示部35、及びスピーカ36を含んでもよい。言い換えると、記録装置50は、再生制御部25、受信制御部29、表示部35、及びスピーカ36を含まなくてもよい。つまり、再生制御部25、受信制御部29、表示部35、及びスピーカ36を含む再生装置等が、外部記録装置5に記録されたデータを再生してもよい。例えば、再生装置等は、光ディスクもしくはカード型記録媒体等の持ち運び可能な記録媒体に記録されたデータを再生する装置であってもよい。外部記録装置5に記録されたデータは、持ち運び可能な記録媒体に移行されてもよい。
6 shows a configuration in which the recording device 50 includes a reproduction control unit 25, a reception control unit 29, a display unit 35, and a speaker 36. However, a reproduction device or the like different from the recording device 50 is used as the reproduction control unit. 25, a reception control unit 29, a display unit 35, and a speaker 36 may be included. In other words, the recording device 50 may not include the reproduction control unit 25, the reception control unit 29, the display unit 35, and the speaker 36. That is, the playback device including the playback control unit 25, the reception control unit 29, the display unit 35, and the speaker 36 may play back the data recorded in the external recording device 5. For example, the playback device or the like may be a device that plays back data recorded on a portable recording medium such as an optical disk or a card-type recording medium. Data recorded in the external recording device 5 may be transferred to a portable recording medium.
ここで、図7は、送信制御部28へ出力されるデータと、バッファメモリ24に記録されるデータとの関係を示している。図7は、記録制御部23が撮影データを記録部33へ記録するのではなく、記録制御部23が撮影データを送信制御部28へ出力することを示している。図7は、記録制御部23が撮影データを送信制御部28へ出力すること以外は、図2と同様の内容を示しているため、詳細な説明を省略する。
Here, FIG. 7 shows the relationship between the data output to the transmission control unit 28 and the data recorded in the buffer memory 24. FIG. 7 shows that the recording control unit 23 does not record the shooting data in the recording unit 33, but the recording control unit 23 outputs the shooting data to the transmission control unit 28. Since FIG. 7 shows the same contents as FIG. 2 except that the recording control unit 23 outputs the photographing data to the transmission control unit 28, detailed description thereof is omitted.
続いて、図8を用いて実施の形態1にかかる撮影データの送信処理の流れについて説明する。はじめに、撮影データ取得部21は、少なくとも映像データを含む撮影データをバッファメモリ24へ出力し、バッファメモリ24は、撮影データの記憶を開始する(S31)。次に、記録制御部23は、バッファメモリ24に記憶されている撮影データの送信制御部28への出力を開始するにあたり、イベントが発生したか否かを判定する(S32)。具体的には、記録制御部23は、移行する撮影データの撮影期間にイベントが発生したか否かを判定する。例えば、記録制御部23は、イベント検出部22において、送信制御部28へ出力する撮影データの撮影期間にイベントの発生が検出されたか否かを判定する。
Subsequently, the flow of the photographing data transmission process according to the first embodiment will be described with reference to FIG. First, the shooting data acquisition unit 21 outputs shooting data including at least video data to the buffer memory 24, and the buffer memory 24 starts storing shooting data (S31). Next, the recording control unit 23 determines whether or not an event has occurred when starting to output the photographing data stored in the buffer memory 24 to the transmission control unit 28 (S32). Specifically, the recording control unit 23 determines whether an event has occurred during the shooting period of the shooting data to be transferred. For example, the recording control unit 23 determines whether the event detection unit 22 detects the occurrence of an event during the shooting period of the shooting data output to the transmission control unit 28.
記録制御部23は、イベントが発生したと判定した場合、プライバシー対策を行うことなく、撮影期間にイベントが発生したタイミングを含む撮影データを送信制御部28へ出力する(S33)。記録制御部23は、プライバシー対策を行うことなくバッファメモリ24に記憶されている撮影データをファイル化して、撮影データを送信制御部28へ出力する。送信制御部28は、出力された撮影データを、送信部38を介して外部記録装置5へ送信する。
When it is determined that the event has occurred, the recording control unit 23 outputs the shooting data including the timing at which the event has occurred during the shooting period to the transmission control unit 28 without taking privacy measures (S33). The recording control unit 23 converts the shooting data stored in the buffer memory 24 into a file without taking a privacy measure, and outputs the shooting data to the transmission control unit 28. The transmission control unit 28 transmits the output shooting data to the external recording device 5 via the transmission unit 38.
記録制御部23は、イベントが発生していないと判定した場合、イベントが発生していない期間に撮影された撮影データに対してプライバシー対策を行う。記録制御部23は、人の顔及び車両のナンバープレートの少なくとも一方が不明瞭となった映像データを含む撮影データを送信制御部28へ出力する(S34)。記録制御部23は、バッファメモリ24に記憶されている撮影データに対してプライバシー対策を行い、プライバシー対策を行った撮影データをファイル化し、撮影データを送信制御部28へ出力する。送信制御部28は、出力された撮影データを、送信部38を介して外部記録装置5へ送信する。
When the recording control unit 23 determines that an event has not occurred, the recording control unit 23 performs privacy countermeasures on the captured data captured during a period in which no event has occurred. The recording control unit 23 outputs to the transmission control unit 28 photographing data including video data in which at least one of the human face and the vehicle license plate is unclear (S34). The recording control unit 23 performs privacy countermeasures on the shooting data stored in the buffer memory 24, files the shooting data on which privacy measures have been taken, and outputs the shooting data to the transmission control unit 28. The transmission control unit 28 transmits the output shooting data to the external recording device 5 via the transmission unit 38.
記録制御部23は、ステップS33もしくはS34においてバッファメモリ24内に記憶されている撮影データを送信制御部28へ出力した後に、予め定められた期間における撮影データの出力を終了したか否かを判定する(S35)。予め定められた期間とは、図7において説明したD-4~D+2の各撮影データの撮影期間であってもよい。例えば、記録制御部23は、撮影データD-2を送信制御部28へ出力している際に、バッファメモリ24内に、送信制御部28へ出力していない撮影データD-2が残っているか否かを判定してもよい。記録制御部23は、バッファメモリ24内に送信制御部28へ出力していない撮影データD-2が残っていないと判定した場合、予め定められた期間における撮影データの出力を終了したと判定してもよい。記録制御部23は、バッファメモリ24内に送信制御部28へ出力していない撮影データD-2が残っていると判定した場合、撮影データD-2の出力を継続する。
The recording control unit 23 determines whether or not the output of the photographic data in a predetermined period has ended after outputting the photographic data stored in the buffer memory 24 to the transmission control unit 28 in step S33 or S34. (S35). The predetermined period may be an imaging period of each of the imaging data D−4 to D + 2 described in FIG. For example, when the recording control unit 23 outputs the photographic data D-2 to the transmission control unit 28, whether or not the photographic data D-2 that has not been output to the transmission control unit 28 remains in the buffer memory 24. It may be determined whether or not. If the recording control unit 23 determines that the shooting data D-2 that has not been output to the transmission control unit 28 does not remain in the buffer memory 24, the recording control unit 23 determines that the output of the shooting data in a predetermined period has ended. May be. When the recording control unit 23 determines that the shooting data D-2 that has not been output to the transmission control unit 28 remains in the buffer memory 24, the recording control unit 23 continues to output the shooting data D-2.
次に、記録制御部23は、バッファメモリ24内に記憶されていた全ての撮影データの出力を終了したか否かを判定する(S36)。記録制御部23は、バッファメモリ24内に記憶されていた全ての撮影データの出力を終了したと判定した場合、処理を終了する。バッファメモリ24内に送信制御部28へ出力していない撮影データが存在しない場合とは、例えば、運転者が撮影を停止する操作を実施した場合、もしくは、エンジンが停止し撮影が停止された場合等がある。
Next, the recording control unit 23 determines whether or not the output of all the shooting data stored in the buffer memory 24 is completed (S36). If the recording control unit 23 determines that the output of all the shooting data stored in the buffer memory 24 has ended, the process ends. The case where there is no shooting data that is not output to the transmission control unit 28 in the buffer memory 24 is, for example, when the driver performs an operation to stop shooting, or when the shooting is stopped because the engine is stopped. Etc.
記録制御部23は、バッファメモリ24内に記憶されていた全ての撮影データの出力が終了していないと判定した場合、ステップS31以降の処理を繰り返し実行する。
When the recording control unit 23 determines that the output of all the shooting data stored in the buffer memory 24 has not been completed, the recording control unit 23 repeatedly executes the processes after step S31.
以上説明したように、実施の形態3にかかる記録装置50は、イベントが発生したタイミングを撮影期間に含む撮影データに関しては、プライバシー対策が行われていない映像データを外部記録装置5へ送信することができる。また、記録装置50は、イベントが発生していない期間に撮影された撮影データに関しては、プライバシー対策が行われ、人の顔及び車両のナンバープレートの少なくとも一方が不明瞭となった映像データを外部記録装置5へ送信することができる。外部記録装置5へ送信された映像データは、外部記録装置において記憶される。これにより、記録装置50は、交通事故等のイベントが発生した際の撮影データに関しては、人の顔や車両のナンバープレートが映っている場合であってもそれらが判別可能な未加工の撮影データが記録されているため事故原因の究明等に役立てることができる。一方、記録装置50は、イベントが発生していない期間の撮影データに関しては、人の顔及び車両のナンバープレートの少なくとも一方を不明瞭とすることによって、車両内外の撮影対象のプライバシーを保護することができる。
As described above, the recording apparatus 50 according to the third embodiment transmits video data for which privacy measures are not taken to the external recording apparatus 5 with respect to shooting data that includes the timing at which an event occurs in the shooting period. Can do. In addition, the recording device 50 externally captures video data in which at least one of the human face and the vehicle license plate is obscured with respect to captured data captured during a period in which no event occurs. It can be transmitted to the recording device 5. The video data transmitted to the external recording device 5 is stored in the external recording device. As a result, the recording device 50 is able to determine the shooting data when an event such as a traffic accident occurs, even if a human face or a license plate of a vehicle is reflected, and the raw shooting data that can be identified. Can be used to investigate the cause of the accident. On the other hand, the recording device 50 protects the privacy of the photographing target inside and outside the vehicle by making at least one of the human face and the vehicle license plate unclear regarding the shooting data during a period in which no event occurs. Can do.
また、撮影データが外部記録装置5に記録されることによって、事故等により車両やドライブレコーダが破損した場合であっても、撮影データの破損消失を防止することができる。
Further, since the shooting data is recorded in the external recording device 5, even if the vehicle or the drive recorder is damaged due to an accident or the like, it is possible to prevent the shooting data from being lost.
(実施の形態4)
続いて、図9を用いて実施の形態2にかかる撮影データの送信処理の流れについて説明する。図9においては、主に、図8と異なる処理について説明する。 (Embodiment 4)
Next, the flow of the photographing data transmission process according to the second embodiment will be described with reference to FIG. In FIG. 9, processing different from that in FIG. 8 will be mainly described.
続いて、図9を用いて実施の形態2にかかる撮影データの送信処理の流れについて説明する。図9においては、主に、図8と異なる処理について説明する。 (Embodiment 4)
Next, the flow of the photographing data transmission process according to the second embodiment will be described with reference to FIG. In FIG. 9, processing different from that in FIG. 8 will be mainly described.
ステップS41は、図8のステップS31と同様であるため詳細な説明を省略する。次に、記録制御部23は、バッファメモリ24に記憶されている撮影データの送信制御部28への出力を開始するにあたり、イベントが発生したか否かを判定する(S42)。
Since step S41 is the same as step S31 in FIG. 8, detailed description thereof is omitted. Next, the recording control unit 23 determines whether or not an event has occurred when starting to output the photographing data stored in the buffer memory 24 to the transmission control unit 28 (S42).
ここで、図10を用いて、イベント検出部22が検出するイベントについて詳細に説明する。図10のセンシングの列には、イベント検出部22が取得する情報もしくはその情報を検知する装置が記載されている。加速度センサは、車両の加速度情報もしくは衝撃情報を検出し、イベント検出部22へ出力する。ユーザ操作とは、ユーザが記録装置50を操作することで、センサ等によらず手動でイベントに起因した記録を開始させるための操作を受け付けることである。速度情報は、例えば、CANを介して取得する車両の速度情報である。音量は、例えば、車両利用者の音声レベルを示す情報である。
Here, the event detected by the event detection unit 22 will be described in detail with reference to FIG. The sensing column in FIG. 10 describes information acquired by the event detection unit 22 or a device that detects the information. The acceleration sensor detects acceleration information or impact information of the vehicle and outputs it to the event detection unit 22. The user operation refers to accepting an operation for manually starting recording due to an event regardless of a sensor or the like when the user operates the recording device 50. The speed information is, for example, vehicle speed information acquired via CAN. The volume is information indicating the sound level of the vehicle user, for example.
イベントの列には、イベント検出部22が取得した情報等に基づいて決定されるイベントの例が記載されている。例えば、イベント検出部22は、加速度センサによって検知された加速度が、閾値1以上であり、さらに衝突を示す閾値2以上である場合、車両が人もしくは物に衝突したと決定する。閾値2は、閾値1よりも大きな値とする。もしくは、イベント検出部22は、加速度の波形形状が衝突を示す波形形状である場合、車両が人もしくは物に衝突したと決定してもよい。また、イベント検出部22は、加速度センサによって検知される加速度が閾値1以上であり閾値2未満である場合、車両が急加速もしくは急減速したと決定する。もしくは、イベント検出部22は、加速度の波形形状が衝突を示す波形形状でない場合、車両が急加速もしくは急減速したと決定してもよい。また、イベント検出部22は、記録装置50の操作部が操作されイベントに起因した記録の開始が指示されたことを検知する。また、イベント検出部22は、ハンドルの回転速度が所定の値を超えているもしくはハンドルの回転量が所定の値を超えている等の場合、運転者が急ハンドルを切ったと決定する。また、イベント検出部22は、車両の速度が所定の値を超えている場合、車両が速度超過状態にあると決定する。また、イベント検出部22は、車両の利用者の音声レベルが所定の値を超えている場合、車両内において人的トラブルが発生したと決定する。
In the event column, an example of an event determined based on information acquired by the event detection unit 22 is described. For example, the event detection unit 22 determines that the vehicle has collided with a person or an object when the acceleration detected by the acceleration sensor is greater than or equal to the threshold value 1 and further greater than or equal to the threshold value 2 indicating a collision. The threshold value 2 is larger than the threshold value 1. Alternatively, the event detection unit 22 may determine that the vehicle has collided with a person or an object when the waveform shape of acceleration is a waveform shape indicating a collision. In addition, when the acceleration detected by the acceleration sensor is greater than or equal to the threshold 1 and less than the threshold 2, the event detection unit 22 determines that the vehicle has accelerated or decelerated suddenly. Alternatively, the event detection unit 22 may determine that the vehicle has suddenly accelerated or decelerated when the waveform shape of acceleration is not a waveform shape indicating a collision. Further, the event detection unit 22 detects that the operation unit of the recording device 50 is operated and an instruction to start recording due to the event is given. Further, the event detection unit 22 determines that the driver has suddenly turned off the steering wheel when the rotational speed of the steering wheel exceeds a predetermined value or the rotational amount of the steering wheel exceeds a predetermined value. In addition, the event detection unit 22 determines that the vehicle is in an overspeed state when the speed of the vehicle exceeds a predetermined value. Moreover, the event detection part 22 determines with the human trouble having generate | occur | produced in the vehicle, when the audio | voice level of the user of a vehicle exceeds the predetermined value.
イベントレベルの列には、それぞれのイベントに関するレベルが記載されている。例えば、衝突及び人的トラブルといったイベントのイベントレベルは、高に設定され、その他のイベントのイベントレベルは、低に設定されている。記録制御部23は、イベントレベルに基づいて、外部記録装置5へ送信する撮影データの種類を決定する。
In the event level column, the level related to each event is described. For example, the event levels of events such as collisions and human troubles are set to high, and the event levels of other events are set to low. The recording control unit 23 determines the type of shooting data to be transmitted to the external recording device 5 based on the event level.
送信データの列には、記録制御部23が送信制御部28及び送信部38を介して外部記録装置5へ送信するデータが記載されている。例えば、記録制御部23は、イベントレベルが高に設定されている場合、映像データ及び音声データを送信する。また、記録制御部23は、イベントレベルが低に設定されている場合、映像データのみを送信する。また、記録制御部23は、イベント検出部22が、加速度センサにおいて検知された情報を用いてイベントを決定した場合、加速度情報も併せて送信してもよい。さらに、記録制御部23は、イベント検出部22が、速度情報を用いてイベントを決定した場合、速度情報も併せて送信してもよい。
In the transmission data column, data that the recording control unit 23 transmits to the external recording device 5 via the transmission control unit 28 and the transmission unit 38 is described. For example, the recording control unit 23 transmits video data and audio data when the event level is set to high. The recording control unit 23 transmits only video data when the event level is set to low. Moreover, the recording control part 23 may also transmit acceleration information together, when the event detection part 22 determines an event using the information detected in the acceleration sensor. Furthermore, when the event detection unit 22 determines an event using the speed information, the recording control unit 23 may also transmit the speed information.
図9に戻り、記録制御部23は、イベント検出部22からイベントの発生が通知された場合、イベントレベルが高であるか否かを判定する(S43)。イベント検出部22は、イベントを検出した場合、図10のイベントの列に記載されているイベントの内容及びイベントレベルを記録制御部23へ通知する。記録制御部23は、イベントレベルが高であると判定した場合、撮影期間にイベントレベルとして高が設定されたイベントが発生したタイミングを含む撮影データを送信制御部28へ出力する(S44)。ステップS44において出力される撮影データは、プライバシー対策が行われていない撮影データである。
Returning to FIG. 9, when the event detection unit 22 is notified of the occurrence of an event, the recording control unit 23 determines whether or not the event level is high (S43). When detecting an event, the event detection unit 22 notifies the recording control unit 23 of the content and event level of the event described in the event column of FIG. If the recording control unit 23 determines that the event level is high, the recording control unit 23 outputs to the transmission control unit 28 shooting data including a timing at which an event having a high event level is set during the shooting period (S44). The shooting data output in step S44 is shooting data for which privacy measures are not taken.
記録制御部23は、ステップS42においてイベント検出部22からイベントの発生が通知されず、イベントが発生していないと判定した場合、及び、ステップS43において、発生したイベントのイベントレベルが高ではないと判定した場合、ステップS45に規定する処理を実行する。ステップS45において、記録制御部23は、イベントが発生していない期間に撮影された撮影データ、もしくは、イベントが発生したタイミングを含む撮影データに対してプライバシー対策を行い、プライバシー対策を行った撮影データを送信制御部28へ出力する。
The recording control unit 23 determines that the event has not been notified from the event detection unit 22 in step S42 and it is determined that no event has occurred. In step S43, the event level of the event that has occurred is not high. When it determines, the process prescribed | regulated to step S45 is performed. In step S <b> 45, the recording control unit 23 performs privacy measures on the shooting data shot during a period in which no event has occurred, or shooting data including the timing at which the event has occurred, and the shooting data for which privacy measures have been taken. Is output to the transmission control unit 28.
ステップS46及びS47は、図8のステップS35及びS36と同様であるため詳細な説明を省略する。
Steps S46 and S47 are the same as steps S35 and S36 in FIG.
以上説明したように、実施の形態4にかかる記録装置50は、発生したイベントのイベントレベルに応じて、プライバシー対策を行った撮影データを外部記録装置5へ送信するか、プライバシー対策を行わない撮影データを外部記録装置5へ送信するかを決定することができる。イベントレベルが高および低のいずれも、イベントに起因した撮影データとして上書き禁止を示すフラグ情報が設定されている。また、外部記録装置5において記録されるデータは、イベントに起因しない撮影データはプライバシー対策が行われて上書き可能に記録され、イベントに起因した撮影データは、イベントレベルが高である場合はプライバシー対策が行われずに記録され、イベントレベルが低である場合はプライバシー対策が行われて記録される。これにより、記録装置50から外部記録装置5へ送信され、上書き禁止として記録された撮影データのうち、事故やトラブルの発生を記録した映像データは、事故やトラブルの原因究明のために人物の顔や車両のナンバープレートなどが参照可能なデータとして記録され、車両の運行状況などを記録した映像データは、プライバシー対策が行われて記録されるため、イベントに起因して記録された撮影データにおいても撮影された人物や車両のプライバシーを保護することができる。
As described above, the recording apparatus 50 according to the fourth embodiment transmits the shooting data with the privacy measures taken to the external recording device 5 according to the event level of the event that has occurred, or the shooting without taking the privacy measures. It is possible to determine whether to transmit data to the external recording device 5. For both high and low event levels, flag information indicating overwriting prohibition is set as shooting data resulting from the event. Further, data recorded in the external recording device 5 is recorded so that photographic data not attributed to an event can be overwritten with a privacy measure, and photographic data attributed to an event is a privacy measure when the event level is high. If the event level is low, privacy measures are taken and recorded. As a result, among the photographic data transmitted from the recording device 50 to the external recording device 5 and recorded as overwriting prohibition, the video data recording the occurrence of the accident or trouble is the person's face for investigating the cause of the accident or trouble. Since the video data that records the vehicle operation status etc. is recorded as data that can be referred to, such as vehicle license plates, etc., since privacy measures are taken and recorded, even in the shooting data recorded due to the event The privacy of the photographed person or vehicle can be protected.

Specifically, the recording device 60 includes an imaging data acquisition unit 21, an event detection unit 22, a recording control unit 23, a detection unit 26, a transmission control unit 28, and a volume level acquisition unit 42.
続いて、図11を用いて実施の形態5にかかる記録装置60の構成例について説明する。記録装置60は、図6の記録装置50における制御部51の代わりに制御部61を有する。また、制御部61は、図6の制御部51に音量レベル取得部42が追加された構成である。記録装置60について、記録装置50と同じ構成については同じ符号を付しており、詳細な説明を省略する。以下に、記録装置60について、記録装置50と異なる構成に関して主に説明する。記録装置60も記録装置50と同様に、制御部61によって実現される構成要素を備える構成としてもよい。具体的には、記録装置60は、撮影データ取得部21、イベント検出部22、記録制御部23、検出部26、送信制御部28、および音量レベル取得部42を備える。 (Embodiment 5)
Next, a configuration example of the
音量レベル取得部42は、マイクロフォン32が生成した音声データから音量レベルに関する情報を取得する。音量レベル取得部42は、撮影データ取得部21が取得した音声データから音量レベルに関する情報を取得してもよい。音量レベルは、例えば、音声のボリュームを示す情報であってもよい。音量レベル取得部42は、音量レベルに関する情報をイベント検出部22へ出力する。具体的には、音量レベルに関する情報には、音声データの識別情報が含まれてもよい。
The volume level acquisition unit 42 acquires information about the volume level from the audio data generated by the microphone 32. The volume level acquisition unit 42 may acquire information related to the volume level from the audio data acquired by the imaging data acquisition unit 21. The volume level may be information indicating the volume of audio, for example. The volume level acquisition unit 42 outputs information related to the volume level to the event detection unit 22. Specifically, the information regarding the sound volume level may include identification information of the audio data.
図11においては、音量レベル取得部42が、マイクロフォン32とイベント検出部22との間に配置されることを示しているが、音量レベル取得部42は、撮影データ取得部21とイベント検出部22との間に配置されてもよい。
In FIG. 11, it is shown that the volume level acquisition unit 42 is disposed between the microphone 32 and the event detection unit 22, but the volume level acquisition unit 42 includes the shooting data acquisition unit 21 and the event detection unit 22. Between the two.
記録制御部23は、音声データに関する音量レベルに応じて、プライバシー対策を行うか否かを決定する。例えば、通常会話レベルの音量と、通常会話レベルを超えた大声との間に音量レベルの閾値1を設ける。つまり、閾値1は、通常会話レベルとそれ以上の音量レベルとを識別するために用いられる。通常会話レベルを超えた大声とは、例えば人間の叫び声もしくは怒鳴り声等であってもよい。音量レベルが閾値1を超えることは、図10に示す人的トラブルが発生したことを示している。つまり、音量レベルが閾値1を超えた場合に、イベント検出部22においてイベントとして人的トラブルが発生したことが検出され、イベントレベルは高に設定される。
The recording control unit 23 determines whether or not to take privacy measures according to the volume level related to the audio data. For example, a threshold value 1 of the sound volume level is provided between the sound volume of the normal conversation level and the loud voice exceeding the normal conversation level. That is, the threshold value 1 is used to distinguish between a normal conversation level and a volume level higher than that. The loud voice exceeding the normal conversation level may be, for example, a human screaming or yelling voice. The volume level exceeding the threshold value 1 indicates that the human trouble shown in FIG. 10 has occurred. That is, when the volume level exceeds the threshold value 1, it is detected in the event detection unit 22 that a human trouble has occurred as an event, and the event level is set to high.
記録制御部23は、音量レベルが閾値1未満の場合、プライバシー対策を行った映像データを外部記録装置5へ送信する。つまり、音量レベルが閾値1未満の場合、イベントは検出されない。
When the volume level is less than the threshold value 1, the recording control unit 23 transmits video data on which privacy measures have been taken to the external recording device 5. That is, when the volume level is less than the threshold value 1, no event is detected.
記録制御部23が閾値1に基づいてプライバシー対策を行うか否かを判定することによって、撮影対象のプライバシーを保護することができる。
The privacy of the subject to be photographed can be protected by determining whether or not the recording control unit 23 takes a privacy measure based on the threshold value 1.
続いて、実施の形態5にかかる撮影データの送信処理の流れについて説明する。実施の形態5にかかる撮影データの送信処理は、図9と同様であるため、図9を用いて、実施の形態5にかかる撮影データの送信処理の流れについて説明する。実施の形態5にかかる撮影データの送信処理は、主に音量レベルに応じた処理である。以下に、図9において音量レベルを用いた処理に関連する内容を説明する。
Subsequently, a flow of processing for transmitting shooting data according to the fifth embodiment will be described. Since the shooting data transmission process according to the fifth embodiment is the same as that in FIG. 9, the flow of the shooting data transmission process according to the fifth embodiment will be described with reference to FIG. The photographing data transmission process according to the fifth embodiment is a process mainly according to the volume level. In the following, contents related to the processing using the volume level in FIG. 9 will be described.
ステップS42において、記録制御部23は、イベント検出部22から人的トラブルに関するイベントが通知されたか否かを判定する。具体的には、イベント検出部22は、音量レベル取得部42から、閾値1を超えた音量レベルを取得したか否かを判定する。イベント検出部22は、音量レベル取得部42において取得された音量レベルが、閾値1を超えている場合、人的トラブルに関するイベントが発生したことを記録制御部23へ通知する。イベント検出部22は、音量レベル取得部42において取得された音量レベルが閾値1未満である場合、人的トラブルに関するイベントが発生していないと判定する。
In step S42, the recording control unit 23 determines whether or not an event related to human trouble is notified from the event detection unit 22. Specifically, the event detection unit 22 determines whether or not a volume level exceeding the threshold 1 has been acquired from the volume level acquisition unit 42. When the volume level acquired by the volume level acquisition unit 42 exceeds the threshold value 1, the event detection unit 22 notifies the recording control unit 23 that an event related to human trouble has occurred. When the volume level acquired by the volume level acquisition unit 42 is less than the threshold value 1, the event detection unit 22 determines that an event related to human trouble has not occurred.
さらに、ステップS43において、記録制御部23は、イベント検出部22から通知されたイベントのイベントレベルが高であるか否かを判定する。図10に示すように、人的トラブルに関するイベントのイベントレベルは高に設定されている。そのため、記録制御部23は、ステップS42において、人的トラブルが発生したことを通知された場合、イベントレベルが高であると判定する。また、イベント検出部22は、音量レベルに関する複数の閾値を有する場合、音量レベルに応じて、人的トラブルに関するイベントレベルを高もしくは低と設定してもよい。このような場合、記録制御部23は、ステップS42において、イベントとして人的トラブルが発生したと判定し、ステップS43において、イベントレベルが高ではない、と判定することがある。
Further, in step S43, the recording control unit 23 determines whether or not the event level of the event notified from the event detection unit 22 is high. As shown in FIG. 10, the event level of an event related to human trouble is set high. Therefore, the recording control unit 23 determines that the event level is high when notified in step S42 that a human trouble has occurred. Further, when the event detection unit 22 has a plurality of threshold values related to the volume level, the event level related to the human trouble may be set to be high or low according to the volume level. In such a case, the recording control unit 23 may determine that a human trouble has occurred as an event in step S42, and may determine that the event level is not high in step S43.
ステップS42及びステップS43以外の処理については、既に説明した内容と同様であるため詳細な説明を省略する。
Since the processes other than step S42 and step S43 are the same as those already described, detailed description thereof will be omitted.
以上説明したように、実施の形態5にかかる記録装置60を用いることによって、音量レベルに応じて撮影データに対してプライバシー対策を行うか否かを判定することができる。これにより、記録装置40は、人的トラブルに相当する音量レベルである場合、プライバシー対策が行われていない撮影データを外部記録装置5へ記録することができる。
As described above, by using the recording device 60 according to the fifth embodiment, it is possible to determine whether or not to take a privacy measure for the photographic data according to the volume level. Thereby, the recording device 40 can record the photographic data for which privacy measures are not taken in the external recording device 5 when the volume level corresponds to a human trouble.
