特開２００３−１０４１３２号公報JP 2003-104132 A

特許文献１に示されるモニタカメラは、助手席、後部座席の確認用や、防犯用において車室内を広角に確認するため、所定の位置（例えば、車両の天井の前後方向の中間）に固定されている。しかし、ユーザが車室内のカメラを用いて確認したい範囲は、車室全体のみならず、例えば、車室の前方を視認する場合は防犯上広域に撮影し、車室の後部を視認する場合には子供が着座している座席のみを撮影したい場合が存在する。車室全体を広角のカメラで撮影した場合には、映像に歪みが発生してユーザにとって違和感のある映像となりやすく、注視したい箇所とそうでない箇所との区別も付け難くなる。   The monitor camera disclosed in Patent Document 1 is fixed at a predetermined position (for example, in the middle in the front-rear direction of the ceiling of the vehicle) in order to confirm the passenger compartment and the rear seat and to check the vehicle interior at a wide angle for crime prevention. ing. However, the range that the user wants to check using the camera in the vehicle interior is not limited to the entire vehicle interior.For example, when viewing the front of the vehicle interior, shooting in a wide area for crime prevention and viewing the rear of the vehicle interior There is a case where the child wants to photograph only the seat where the child is seated. When the entire passenger compartment is photographed with a wide-angle camera, the image is distorted and the user tends to have an uncomfortable feeling, and it is difficult to distinguish between a portion to be watched and a portion that is not.

そこで、本発明では、カメラの撮像部の向きに応じて最適な態様の画像を表示部に表示する車室内カメラ装置を提供する。   Therefore, the present invention provides a vehicle interior camera device that displays an image in an optimum mode on the display unit in accordance with the orientation of the imaging unit of the camera.

本発明に係る車室内カメラ装置の第１特徴構成は、車両の室内に配置され、撮像部が内蔵されて当該撮像部の向きを変更可能に構成されたカメラと、前記撮像部の向きを判定する方向判定部と、前記撮像部の向きに応じて撮影画像の表示態様を切換えて表示部に表示させる制御部と、を備えた点にある。   A first feature configuration of a vehicle interior camera device according to the present invention is a camera that is arranged in a vehicle interior and includes an imaging unit and is configured to change the orientation of the imaging unit, and the orientation of the imaging unit is determined. And a control unit that switches the display mode of the captured image according to the orientation of the imaging unit and displays the captured image on the display unit.

この構成によると、車室内に配置されたカメラの撮像部の向きを変更することで、表示部によって表示される車室内の様子を容易に確認することができる。また、撮像部の向きを判定する方向判定部と、撮像部の向きに応じて撮影画像の表示態様を切換えて表示部に表示させる制御部とを備えるので、例えば、撮像部の向きが車両の前方のときは撮影画像を広角画像にし、撮像部の向きが車両の後方のときは撮影画像を狭い範囲の画像に切換えることができるなど、カメラの向きによって確認したい情報を確実に表示するカメラ装置を得ることができる。   According to this configuration, by changing the orientation of the imaging unit of the camera disposed in the vehicle interior, it is possible to easily confirm the state of the vehicle interior displayed by the display unit. In addition, since it includes a direction determination unit that determines the orientation of the imaging unit, and a control unit that switches the display mode of the captured image according to the orientation of the imaging unit and displays it on the display unit, for example, the orientation of the imaging unit is the vehicle A camera device that reliably displays information to be confirmed depending on the orientation of the camera, such as when the front is a wide-angle image, and when the imaging unit is behind the vehicle, the captured image can be switched to a narrow range of images. Can be obtained.

本発明に係る車室内カメラ装置の第２特徴構成は、前記制御部が、前記撮像部の向きが車両の前方の場合に前記撮影画像を正像に切換え、前記撮像部の向きが車両の後方の場合に前記撮影画像を鏡像に切換可能に構成してある点にある。   According to a second characteristic configuration of the vehicle interior camera device according to the present invention, the control unit switches the captured image to a normal image when the orientation of the imaging unit is the front of the vehicle, and the orientation of the imaging unit is the rear of the vehicle. In this case, the captured image can be switched to a mirror image.

運転席のユーザにとって、車両前方の撮影画像は実画像である正像表示で特に問題はないが、車両後方の撮影画像については正像で表示されるよりも鏡像で表示される方が画像の違和感が少ない。
そこで、本構成の如く、制御部が、撮像部の向きが車両の前方の場合に撮影画像を正像に切換え、撮像部の向きが車両の後方の場合に撮影画像を鏡像に切換可能に構成すると、運転席のユーザにおいて車両の後方の画像把握が容易となる。 For the driver's seat user, the captured image in front of the vehicle has no problem with the normal image display that is a real image, but the captured image of the rear of the vehicle is displayed as a mirror image rather than displayed as a normal image. There is little discomfort.
Therefore, as in this configuration, the control unit can switch the captured image to a normal image when the orientation of the imaging unit is in front of the vehicle, and can switch the captured image to a mirror image when the orientation of the imaging unit is behind the vehicle. Then, it becomes easy for the user at the driver's seat to grasp the image behind the vehicle.

本発明に係る車室内カメラ装置の第３特徴構成は、前記方向判定部が前記カメラに配置してある点にある。   A third characteristic configuration of the in-vehicle camera device according to the present invention is that the direction determination unit is arranged in the camera.

この構成のように、撮像部の向きを判定する方向判定部がカメラに配置してあると、撮像部の向きの変更がカメラで直ぐに検知することができる。また、カメラのみで撮像部の向きが判定されるので、方向判定部の構成を簡素化することができる。   If the direction determination unit that determines the orientation of the imaging unit is arranged in the camera as in this configuration, a change in the orientation of the imaging unit can be detected immediately by the camera. In addition, since the orientation of the imaging unit is determined only by the camera, the configuration of the direction determination unit can be simplified.

本発明に係る車室内カメラ装置の第４特徴構成は、前記方向判定部を加速度センサで構成した点にある。   A fourth characteristic configuration of the vehicle interior camera device according to the present invention is that the direction determination unit is configured by an acceleration sensor.

この構成のように、方向判定部が加速度センサで構成してあると、カメラに加えられた加速度に基づいてカメラの移動量や傾き等を演算することができる。よって、撮像部の向きを容易に判定することができる。   As in this configuration, when the direction determination unit is configured by an acceleration sensor, it is possible to calculate the amount of movement, inclination, and the like of the camera based on the acceleration applied to the camera. Therefore, it is possible to easily determine the orientation of the imaging unit.

本発明に係る車室内カメラ装置の第５特徴構成は、前記方向判定部が地磁気センサを備えた点にある。   A fifth characteristic configuration of the vehicle interior camera device according to the present invention is that the direction determination unit includes a geomagnetic sensor.

この構成のように、方向判定部が地磁気センサを備えていると、地磁気センサによってカメラの撮像部の方位を検知することができる。これにより、カメラを撮像部が傾きのない状態で使用する場合には、地磁気センサによってカメラの撮像部の方向を判定することができる。また、加速度センサと地磁気センサとを共に使用すると、加速度センサによってカメラに加えられた加速度に基づくカメラの移動量や傾き等が演算でき、地磁気センサによって水平角度についての絶対的な姿勢を知ることができるので、撮像部の方向判定の精度が向上する。   When the direction determination unit includes a geomagnetic sensor as in this configuration, the orientation of the imaging unit of the camera can be detected by the geomagnetic sensor. Accordingly, when the camera is used in a state where the imaging unit is not tilted, the direction of the imaging unit of the camera can be determined by the geomagnetic sensor. If both the acceleration sensor and the geomagnetic sensor are used, the amount of movement and tilt of the camera can be calculated based on the acceleration applied to the camera by the acceleration sensor, and the absolute attitude with respect to the horizontal angle can be known by the geomagnetic sensor. Therefore, the accuracy of the direction determination of the imaging unit is improved.

本発明に係る車室内カメラ装置の第６特徴構成は、前記方向判定部が前記車両の固定部に対して前記カメラを回動自在に支持する可動支持部で構成してある点にある。   A sixth characteristic configuration of the in-vehicle camera device according to the present invention is that the direction determination unit includes a movable support unit that rotatably supports the camera with respect to a fixed unit of the vehicle.

この構成のように、方向判定部が前記車両の固定部に対してカメラを回動自在に支持する可動支持部で構成してあると、車両の固定部に対する可動支持部の回転角度の変化の検知が可能となる。したがって、この可動支持部に例えば、回転角度検出機構を設けることで、カメラの撮像部の向きを正確に知ることができる。回転角度検出機構は、例えば回転接点スイッチや、ロータリーエンコーダ等によって構成される。   As in this configuration, if the direction determination unit is configured by a movable support unit that rotatably supports the camera with respect to the fixed part of the vehicle, the rotation angle of the movable support part with respect to the fixed part of the vehicle is changed. Detection is possible. Therefore, by providing, for example, a rotation angle detection mechanism in the movable support portion, the orientation of the image pickup portion of the camera can be accurately known. The rotation angle detection mechanism is configured by a rotary contact switch, a rotary encoder, or the like, for example.

本発明に係る車室内カメラ装置の第７特徴構成は、前記方向判定部が、前記カメラの向きを検出するよう前記カメラに配置されたカメラ方向検出部と、前記車両の向きを検出するよう前記車両に配置された車両方向検出部とで構成してある点にある。   According to a seventh characteristic configuration of the vehicle interior camera device according to the present invention, the direction determination unit includes a camera direction detection unit disposed in the camera so as to detect the direction of the camera, and the direction determination unit detects the direction of the vehicle. It is in the point comprised with the vehicle direction detection part arrange | positioned at the vehicle.

カメラのみに方向判定部が配置されており、車両が走行中の場合には、方向判定部の検出データがカメラの動作によるものか、車両の走行動作によるものかが区別ができない場合がある。本構成の如く、カメラの向きを検出するようカメラに配置されたカメラ方向検出部と、車両の向きを検出するよう車両に配置された車両方向検出部とで構成してあると、カメラ方向検出部の検出データの変位と車両方向検出部の検出データとの相対的変位を比較することで、車両に対するカメラのみの動作を判別することができる。また、カメラ方向検出部の検出データを車両方向検出部の検出データによって補正することができるので、撮像部の向きの判定精度が向上する。   When the direction determination unit is disposed only in the camera and the vehicle is traveling, it may not be possible to distinguish whether the detection data of the direction determination unit is from the operation of the camera or from the traveling operation of the vehicle. As shown in this configuration, when the camera direction detection unit arranged in the camera to detect the camera direction and the vehicle direction detection unit arranged in the vehicle to detect the vehicle direction are detected, the camera direction detection By comparing the relative displacement of the detection data of the part and the detection data of the vehicle direction detection part, it is possible to determine the operation of only the camera with respect to the vehicle. Moreover, since the detection data of the camera direction detection unit can be corrected by the detection data of the vehicle direction detection unit, the determination accuracy of the orientation of the imaging unit is improved.

本発明に係る車室内カメラ装置の第８特徴構成は、前記カメラ方向検出部及び前記車両方向検出部を地磁気センサで構成した点にある。   An eighth characteristic configuration of the vehicle interior camera device according to the present invention is that the camera direction detection unit and the vehicle direction detection unit are configured by a geomagnetic sensor.

この構成のように、カメラ方向検出部及び車両方向検出部が地磁気センサで構成してあると、カメラ及び車両に配置された地磁気センサによって撮像部の方位と車両の方位がそれぞれ検知でき、両方位の比較によって車両に対する撮像部の向きを確実に判定することができる。   When the camera direction detection unit and the vehicle direction detection unit are configured by a geomagnetic sensor as in this configuration, the orientation of the imaging unit and the vehicle direction can be detected by the geomagnetic sensor disposed in the camera and the vehicle, respectively. Thus, the orientation of the image pickup unit with respect to the vehicle can be reliably determined.

本発明に係る車室内カメラ装置の第９特徴構成は、前記カメラ方向検出部及び前記車両方向検出部がさらに加速度センサを備えた点にある。   A ninth characteristic configuration of the vehicle interior camera device according to the present invention is that the camera direction detection unit and the vehicle direction detection unit further include an acceleration sensor.

この構成のように、カメラ方向検出部及び車両方向検出部が地磁気センサに加えて、さらに加速度センサを備えていると、撮像部の方向検出と車両の方向検出の精度が加速度センサよって向上するので、結果的に車両に対する撮像部の向きの判定精度が向上する。   If the camera direction detection unit and the vehicle direction detection unit have an acceleration sensor in addition to the geomagnetic sensor as in this configuration, the accuracy of the direction detection of the imaging unit and the vehicle direction detection is improved by the acceleration sensor. As a result, the accuracy of determining the orientation of the imaging unit with respect to the vehicle is improved.

The camera 10 is covered with an elastic resin material or the like to absorb an impact when it interferes with another object, and has a rounded shape as a whole. When the user manually operates the camera 10 or the flexible arm 12, the position of the camera 10 can be changed. The flexible arm 12 is configured to hold the camera 10 at the position when the user's operating force stops working.

このような車室内カメラ装置であれば、ユーザが運転席２５から自らの手でカメラ１０またはフレキシブルアーム１２を操作することで、カメラ１０の向きを自由に変更することが可能となる。その結果、例えば、ユーザが運転中に、後部座席２６に着座させた子供の様子を確認したい場合には、カメラ１０の撮像部１１を後部座席２６の方向にするだけで、表示部４によって後部座席２６の子供の様子を容易に確認することができる。   With such a vehicle interior camera device, the user can freely change the orientation of the camera 10 by operating the camera 10 or the flexible arm 12 with his / her hand from the driver's seat 25. As a result, for example, when the user wants to check the state of the child seated on the rear seat 26 while driving, the display unit 4 simply moves the imaging unit 11 of the camera 10 in the direction of the rear seat 26. The state of the child in the seat 26 can be easily confirmed.

カメラ１０の撮像部１１を後部座席２６に向けて、表示部４に表示される後部座席２６の乗員の様子を視認することで、後部座席２６の乗員とのコミュニケーション手段として利用することもできる。カメラ１０の撮像部１１を車両２の進行方向に対して斜め前方に向けた場合には、運転中の車外の景色を表示部４で楽しむことや、その景色を表示部４に記録することも可能となる。   The imaging unit 11 of the camera 10 is pointed toward the rear seat 26 and the state of the occupant of the rear seat 26 displayed on the display unit 4 is visually recognized, so that it can be used as a means for communicating with the occupant of the rear seat 26. When the imaging unit 11 of the camera 10 is directed obliquely forward with respect to the traveling direction of the vehicle 2, it is possible to enjoy the scenery outside the vehicle while driving or to record the scenery on the display unit 4. It becomes possible.

また、カメラ１０の撮像部１１をユーザ自身に向けた場合には、例えば自身の後姿の確認や、後ろ髪のセット直し等にも使用することが可能である。防犯対策として、車室内全体の撮影や、車室の前方のみを撮影することも可能となる。   Further, when the image pickup unit 11 of the camera 10 is directed toward the user himself / herself, it can be used for, for example, confirming the rear view of the user 10 or setting the back hair. As a security measure, it is possible to shoot the entire vehicle interior or only the front of the vehicle interior.

ユーザがカメラ１０の位置や向きを自由に変更可能であるので、撮像部１１の角度／方向がその都度ユーザによるカメラ１０の操作によって任意に決定されることとなる。そこで、図５に示すように、カメラ１０にカメラ１０の向きを検出するカメラ方向検出部１４を配置する。本実施形態では、このカメラ方向検出部１４が撮像部１１の向きを判定する方向判定部である。カメラ方向検出部１４には、例えば３軸の加速度センサを用いる。コントローラ３には、撮像部１１の向きを加速度センサの検出データを基づいて判定して映像切換処理が可能な処理演算部Ａを設ける。   Since the user can freely change the position and orientation of the camera 10, the angle / direction of the imaging unit 11 is arbitrarily determined by the operation of the camera 10 by the user each time. Therefore, as shown in FIG. 5, a camera direction detection unit 14 that detects the orientation of the camera 10 is arranged in the camera 10. In the present embodiment, the camera direction detection unit 14 is a direction determination unit that determines the orientation of the imaging unit 11. For the camera direction detection unit 14, for example, a triaxial acceleration sensor is used. The controller 3 is provided with a processing calculation unit A that can determine the direction of the imaging unit 11 based on the detection data of the acceleration sensor and can perform video switching processing.

カメラ方向検出部１４として用いられる加速度センサは、カメラ１０に加速度運動が加えられた時の移動加速度とその移動量、及び、その傾きを検知する。加速度センサに加えて、カメラ方向検出部１４として、地磁気センサを用いることもできる。地磁気センサは、カメラ１０の撮像部１１の方位を検知する。したがって、カメラ方向検出部１４として加速度センサと地磁気センサとを共に使用すると、加速度センサによってカメラ１０の移動量や傾き等が演算でき、地磁気センサによって水平角度についての絶対的な姿勢を知ることができるので、撮像部１１の方向判定の精度が向上する。なお、カメラ１０を撮像部１１の傾きがない状態で使用する場合には、カメラ方向検出部１４として加速度センサに代えて地磁気センサを用いることができ、地磁気センサによって撮像部１１の方向判定が可能となる。   The acceleration sensor used as the camera direction detection unit 14 detects the movement acceleration when the acceleration motion is applied to the camera 10, its movement amount, and its inclination. In addition to the acceleration sensor, a geomagnetic sensor may be used as the camera direction detection unit 14. The geomagnetic sensor detects the orientation of the imaging unit 11 of the camera 10. Therefore, when both the acceleration sensor and the geomagnetic sensor are used as the camera direction detection unit 14, the movement amount, the inclination, and the like of the camera 10 can be calculated by the acceleration sensor, and the absolute attitude with respect to the horizontal angle can be known by the geomagnetic sensor. Therefore, the accuracy of the direction determination of the imaging unit 11 is improved. When the camera 10 is used in a state where the imaging unit 11 is not tilted, a geomagnetic sensor can be used as the camera direction detection unit 14 instead of the acceleration sensor, and the direction of the imaging unit 11 can be determined by the geomagnetic sensor. It becomes.

処理演算部Ａでは、まず、カメラ方向検出部１４により検出された検出データに基づいて撮像部１１の向きがカメラ方向演算部３１で演算され、カメラ方向演算部３１の演算結果を受けて方向判定演算部３０において撮像部１１の方向が判定される。次に、映像取得部３３に入力された撮影画像と方向判定演算部３０の演算結果とを受けて、方向判定演算部３０において撮像部１１の向きが車両２の後方と判定された場合は、映像切換処理部３４で撮影画像を正像から鏡像に切換えられる。その後、撮影画像または映像切換処理後の画像が送信部３９から表示部４に送信される。   In the processing calculation unit A, first, the orientation of the imaging unit 11 is calculated by the camera direction calculation unit 31 based on the detection data detected by the camera direction detection unit 14, and the direction determination is performed based on the calculation result of the camera direction calculation unit 31. The direction of the imaging unit 11 is determined in the calculation unit 30. Next, when the captured image input to the video acquisition unit 33 and the calculation result of the direction determination calculation unit 30 are received and the direction determination calculation unit 30 determines that the direction of the imaging unit 11 is the rear of the vehicle 2, The video switching processor 34 switches the captured image from a normal image to a mirror image. Thereafter, the captured image or the image after the video switching process is transmitted from the transmission unit 39 to the display unit 4.

[第３実施形態]
フレキシブルアーム１２によってカメラ１０は車両２の前後左右方向に加えて、上下方向にも移動できる。このため、カメラ１０側（移動側）と車両２側（固定側）の相対位置の関係から撮像部１１の向きを判定すると方向判定の精度が向上する。
そこで、図６に示すように、第２実施形態においてカメラ１０側に配置されたカメラ方向検出部１４に加えて、車両２側にも車両２の向き検出する車両方向検出部２０を設ける。本実施形態では、カメラ方向検出部１４及び車両方向検出部２０が撮像部１１の向きを判定する方向判定部である。 [Third embodiment]
The flexible arm 12 allows the camera 10 to move in the vertical direction in addition to the front-rear and left-right directions of the vehicle 2. For this reason, if the direction of the imaging part 11 is determined from the relationship between the relative positions of the camera 10 (moving side) and the vehicle 2 (fixed side), the accuracy of the direction determination is improved.
Therefore, as shown in FIG. 6, in addition to the camera direction detection unit 14 arranged on the camera 10 side in the second embodiment, a vehicle direction detection unit 20 for detecting the direction of the vehicle 2 is also provided on the vehicle 2 side. In the present embodiment, the camera direction detection unit 14 and the vehicle direction detection unit 20 are direction determination units that determine the orientation of the imaging unit 11.

本実施形態では、カメラ１０側（移動側）と車両２側（固定側）の相対位置の関係から撮像部の１１の向きを判定するので、カメラ１０側のカメラ方向検出部１４、車両方向検出部２０に、各々の方位が正確な検出できる地磁気センサを用いる。カメラ方向検出部１４、車両方向検出部２０として、地磁気センサに加えて、加速度センサを用いることもできる。例えば、カメラ１０側に携帯端末やＡＶ機器といった磁力を発生させる機器が近づいたときに地磁気センサの検出データに誤差が発生するおそれがある。このような場合に、加速度センサにより地磁気センサの検出データを補正することで撮像部の１１の向きをより確実に判定できる。   In this embodiment, since the orientation of the imaging unit 11 is determined from the relationship between the relative positions of the camera 10 side (moving side) and the vehicle 2 side (fixed side), the camera direction detection unit 14 on the camera 10 side, vehicle direction detection As the unit 20, a geomagnetic sensor capable of accurately detecting each direction is used. As the camera direction detection unit 14 and the vehicle direction detection unit 20, an acceleration sensor can be used in addition to the geomagnetic sensor. For example, an error may occur in the detection data of the geomagnetic sensor when a device that generates magnetic force such as a mobile terminal or AV device approaches the camera 10 side. In such a case, the orientation of the imaging unit 11 can be more reliably determined by correcting the detection data of the geomagnetic sensor by the acceleration sensor.

コントローラ３の処理演算部Ａでは、まず、カメラ方向検出部１４の検出データに基づいてカメラ方向演算部３０でカメラ１０の方向が演算され、車両方向検出部２０の検出データに基づいて車両方向演算部３２で車両２の方向が演算される。次に、カメラ方向演算部３０及び車両方向演算部３２の演算結果を受けて方向判定演算部３１で撮像部１１の車両２に対する向きが判定される。次に、映像取得部３３に入力された撮影画像と方向判定演算部３１の演算結果とを受けて、方向判定演算部３１において撮像部１１の向きが車両２の後方と判定されると、映像切換処理部３４で撮影画像を正像から鏡像に切換える。その後、撮影画像または映像切換処理後の画像が送信部３９から表示部４に送信される。   In the processing calculation unit A of the controller 3, first, the camera direction calculation unit 30 calculates the direction of the camera 10 based on the detection data of the camera direction detection unit 14, and the vehicle direction calculation based on the detection data of the vehicle direction detection unit 20. The direction of the vehicle 2 is calculated by the unit 32. Next, in response to the calculation results of the camera direction calculation unit 30 and the vehicle direction calculation unit 32, the direction determination calculation unit 31 determines the orientation of the imaging unit 11 with respect to the vehicle 2. Next, in response to the captured image input to the video acquisition unit 33 and the calculation result of the direction determination calculation unit 31, the direction determination calculation unit 31 determines that the direction of the imaging unit 11 is the rear of the vehicle 2. The switching processing unit 34 switches the captured image from a normal image to a mirror image. Thereafter, the captured image or the image after the video switching process is transmitted from the transmission unit 39 to the display unit 4.

[第４実施形態]
上記の第２及び第３実施形態では、ユーザがカメラ１０の位置や向きをフレキシブルアーム１２によって自由に変更可能であるので、撮像部１１の角度／方向がその都度ユーザによるカメラ１０の操作によって任意に決定されることとなる。携帯端末のように、表示部とカメラが一体となったものでは、傾いたカメラ映像をそのまま表示部に表示させても、カメラ自体も傾けることができるためユーザにとって違和感のない映像を表示することができる。しかし、車両に搭載されるカメラのように、移動自在とはいえ、一旦方向を変化させた後にカメラから手を離す構成のものでは、カメラが傾いて設定されると表示部にもやはり傾いた画像が表示されることとなり、非常に見づらい映像となる。 [Fourth embodiment]
In the second and third embodiments described above, since the user can freely change the position and orientation of the camera 10 by the flexible arm 12, the angle / direction of the imaging unit 11 can be arbitrarily set by the user operating the camera 10 each time. Will be determined. When the display unit and camera are integrated like a portable terminal, even if the tilted camera image is displayed on the display unit as it is, the camera itself can be tilted, so that the user can display an image that does not feel strange. Can do. However, although it is movable like a camera mounted on a vehicle, if it is configured to release the hand from the camera after changing the direction once, it will also tilt to the display when the camera is tilted. An image will be displayed, and the video will be very difficult to see.

そこで、このような不具合を解消するために、本実施形態では、図７に示すように、カメラ１０に撮像部１１の姿勢を検出する撮像姿勢検出部１５と、車両２に車両２の姿勢を検出する車両姿勢検出部２１とをそれぞれ配置し、コントローラ３には、撮像部１１による撮影画像を回転補正が可能な処理演算部Ａを設ける。撮像姿勢検出部１５及び車両姿勢検出部２１として、加速度センサを用いる。   Therefore, in order to eliminate such problems, in this embodiment, as shown in FIG. 7, the camera 10 detects the posture of the imaging unit 11 and the vehicle 2 has the posture of the vehicle 2 as shown in FIG. A vehicle attitude detection unit 21 to be detected is disposed, and the controller 3 is provided with a processing calculation unit A capable of rotationally correcting the image captured by the imaging unit 11. An acceleration sensor is used as the imaging posture detection unit 15 and the vehicle posture detection unit 21.

コントローラ３の処理演算部Ａにおける撮像部１１の方向判定演算は、上述の第４実施形態と同様に、カメラ方向演算部３０、車両方向演算部３２、方向判定演算部３１、映像切換処理部３４によって行う。一方、撮像部１１の回転判定演算は、撮像姿勢検出部１５の検出データに基づいてカメラ姿勢演算部３５で撮像部１１の姿勢が演算され、車両姿勢検出部２１の検出データに基づいて車両姿勢演算部３７で車両２の姿勢が演算される。   The direction determination calculation of the imaging unit 11 in the processing calculation unit A of the controller 3 is similar to the fourth embodiment described above, the camera direction calculation unit 30, the vehicle direction calculation unit 32, the direction determination calculation unit 31, and the video switching processing unit 34. Do by. On the other hand, in the rotation determination calculation of the image pickup unit 11, the posture of the image pickup unit 11 is calculated by the camera posture calculation unit 35 based on the detection data of the image pickup posture detection unit 15, and the vehicle posture based on the detection data of the vehicle posture detection unit 21. The calculation unit 37 calculates the attitude of the vehicle 2.

次に、カメラ姿勢演算部３５及び車両姿勢演算部３７の演算結果を受け、回転判定演算部３６で撮像部１１の回転が判定される。次に、映像取得部３３に入力された撮影画像と回転判定演算部３６の演算結果とを受けて、回転判定演算部３６において撮像部１１が回転状態と判定されると、映像回転処理部３８において撮影画像の回転補正である映像回転処理がカメラ姿勢演算部３５の演算結果に基づいて行われる。その後、撮影画像または映像回転処理後の画像が送信部３９から表示部４に送信される。   Next, the rotation determination calculation unit 36 determines the rotation of the imaging unit 11 based on the calculation results of the camera posture calculation unit 35 and the vehicle posture calculation unit 37. Next, in response to the captured image input to the video acquisition unit 33 and the calculation result of the rotation determination calculation unit 36, when the rotation determination calculation unit 36 determines that the imaging unit 11 is in the rotation state, the video rotation processing unit 38. The image rotation process, which is the rotation correction of the captured image, is performed based on the calculation result of the camera posture calculation unit 35. Thereafter, the captured image or the image after the video rotation process is transmitted from the transmission unit 39 to the display unit 4.

こうして、撮像部１１の回転が判定された際には、処理演算部Ａによって撮影画像が回転補正され、表示部４に表示される画像は例えば、常に傾きのない水平な画像となる。その結果、表示部４の画像を視認するユーザの違和感も少なくなる。   Thus, when the rotation of the imaging unit 11 is determined, the captured image is rotationally corrected by the processing calculation unit A, and the image displayed on the display unit 4 is always a horizontal image without inclination, for example. As a result, the uncomfortable feeling of the user who visually recognizes the image on the display unit 4 is reduced.
