Description

本発明は、撮影装置に関するものである。 The present invention relates to a photographing device.

従来、照明を用いて撮影を行う際に、本撮影の前に行われた予備発光（プリ発光、モニタ発光）の結果を用いて本発光量を算出する撮影装置がある。さらに、１回目の予備発光結果の受光量が所定値以下の場合、１回目よりも発光強度を大きくした２回目の予備発光を指示する撮影装置がある（特許文献１参照）。 Conventionally, when shooting with lighting, there is a shooting device that calculates the main light emission amount using the result of preliminary light emission (pre-light emission, monitor light emission) performed before the main shooting. Further, when the light receiving amount of the first preliminary light emission result is equal to or less than a predetermined value, there is a photographing device instructing the second preliminary light emission having a higher light emission intensity than the first time (see Patent Document 1).

図１に示すカメラ１は、カメラ本体１０と、カメラ本体１０に着脱されるレンズ鏡筒２２とを備える一眼レフデジタルスチルカメラ１である。 FIG. 1 is a diagram showing an embodiment of the camera 1 according to the present invention. Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The camera 1 shown in FIG. 1 is a single-lens reflex digital still camera 1 including a camera body 10 and a lens barrel 22 attached to and detached from the camera body 10.

本実施形態のカメラ１は、カメラ本体１０にレンズ鏡筒２２が交換可能に装着される。
カメラ本体１０は被写体像を撮像して画像を記録するための撮影用撮像素子２１を備える。この撮影用撮像素子２１はＣＣＤやＣＭＯＳなどにより構成することができる。

カメラ本体１０の底部には、レンズ鏡筒２２の焦点調節状態を検出するための焦点検出光学系２４と測距素子２５が設けられている。
焦点検出光学系２４は、レンズ鏡筒２２を通過した対の焦点検出用光束を測距素子２５の受光面へ導き、対の光像を結像させる。
測距素子２５は例えば対のＣＣＤラインセンサーを備え、対の光像に応じた焦点検出信号を出力する。 At the bottom of the camera body 10, a focus detection optical system 24 and a distance measuring element 25 for detecting the focus adjustment state of the lens barrel 22 are provided.
The focal detection optical system 24 guides the pair of focal detection light fluxes that have passed through the lens barrel 22 to the light receiving surface of the ranging element 25, and forms a pair of optical images.
The distance measuring element 25 includes, for example, a pair of CCD line sensors, and outputs a focus detection signal corresponding to the pair of optical images.

撮影前にはクイックリターンミラー１１およびサブミラー２３が破線で示すような撮影光路内の位置に設定されており、レンズ鏡筒２２からの対の焦点検出用光束はクイックリターンミラー１１のハーフミラー部を透過し、サブミラー２３により反射されて焦点検出光学系２４および測距素子２５へ導かれる。 Before shooting, the quick return mirror 11 and the sub mirror 23 are set at positions in the shooting optical path as shown by the broken line, and the pair of focal detection light beams from the lens barrel 22 is the half mirror portion of the quick return mirror 11. It is transmitted, reflected by the submirror 23, and guided to the focus detection optical system 24 and the ranging element 25.

カメラ本体１０の上部にはファインダー光学系が設けられている。撮影前にはクイックリターンミラー１１およびサブミラー２３が破線で示す位置にあり、レンズ鏡筒２２からの被写体光はクイックリターンミラー１１に反射されて焦点板１２へ導かれ、焦点板１２上に被写体像が結像する。 A finder optical system is provided on the upper part of the camera body 10.

液晶表示素子１３は、焦点板１２上に結像された被写体像に焦点検出エリアマークなどの情報を重畳表示するとともに、被写体像外の位置に露出値などの種々の撮影情報を表示する。焦点板１２上の被写体像はペンタダハプリズム１４および接眼レンズ１５を介して接眼窓１６へ導かれ、撮影者が被写体像を視認することができる。 The liquid crystal display element 13 superimposes and displays information such as a focus detection area mark on the subject image formed on the focal plate 12, and also displays various shooting information such as an exposure value at a position outside the subject image. The subject image on the focal plate 12 is guided to the eyepiece window 16 via the pentadha prism 14 and the eyepiece lens 15, and the photographer can visually recognize the subject image.

また、カメラ本体１０上部のファインダー光学系には、（被写体追尾や）測光のために被写体像を撮像する測光センサ１９が設けられる。撮影前に焦点板１２に結像した被写体像は、ペンタダハプリズム１４、プリズム１７および結像レンズ１８を介して測光センサ１９の受光面に再結像される。測光センサ１９は被写体像に応じた画像信号を出力する。 Further, the finder optical system on the upper part of the camera body 10 is provided with a photometric sensor 19 that captures a subject image for (subject tracking and) photometry. The subject image imaged on the focal plate 12 before shooting is reimaged on the light receiving surface of the photometric sensor 19 via the pentadha prism 14, the prism 17, and the imaging lens 18. The photometric sensor 19 outputs an image signal according to the subject image.

測光センサ１９は比較的高解像な撮像素子であり、ＲＧＢの原色フィルターを設けることで、結像画像のＲＧＢの各色情報を得ることが可能となる。 The photometric sensor 19 is an image pickup device having a relatively high resolution, and by providing an RGB primary color filter, it is possible to obtain RGB color information of the imaged image.

カメラ本体１０には、カメラ制御部３０が設けられている。カメラ制御部３０はカメラ１の種々の制御と演算を行う。 The camera body 10 is provided with a camera control unit 30. The camera control unit 30 performs various controls and calculations for the camera 1.

レリーズスイッチ２０の全押しにより撮影が実行される場合にはクイックリターンミラー１１が実線で示す位置に回動し、被写体光はレリーズスイッチ２０を介して撮影用撮像素子２１上に結像する。 When shooting is executed by fully pressing the release switch 20, the quick return mirror 11 rotates to the position indicated by the solid line, and the subject light is imaged on the image pickup device 21 for shooting via the release switch 20.

カメラ本体１０には内蔵または外付けの照明装置２６が備えられている。
照明装置２６は、キセノン管２９、反射板２７、及び発光制御部２８とを備える。発光制御部２８は、カメラ制御部３０からの指示によりキセノン管２９の発光制御を行う。 The camera body 10 is provided with a built-in or external lighting device 26.
The lighting device 26 includes a xenon tube 29, a reflector 27, and a light emission control unit 28. The light emission control unit 28 controls the light emission of the xenon tube 29 according to an instruction from the camera control unit 30.

カメラ制御部３０は、レリーズスイッチ全押しにより撮影が実行される際に、クイックリターンミラー１１が点線位置にある状態にて照明装置２６に予備発光を行わせる。
カメラ制御部３０は、その予備発光時における被写体からの反射光を測光センサ１９によって受光して、その反射光量（予備発光時測光値）に基づいて本発光時の発光量を出する。 The camera control unit 30 causes the lighting device 26 to perform preliminary light emission while the quick return mirror 11 is in the dotted line position when shooting is executed by fully pressing the release switch.
The camera control unit 30 receives the reflected light from the subject at the time of the preliminary light emission by the photometric sensor 19, and outputs the light emission amount at the time of the main light emission based on the reflected light amount (photometric value at the time of the preliminary light emission).

カメラ制御部３０は、算出した本発光量を照明装置２６の発光制御部２８に通知し、クイックリターンミラー１１を実線位置に回動させ、撮影用の露光時のタイミングで、照明装置２６に指示した発光量にて本発光を行わせる。 The camera control unit 30 notifies the light emission control unit 28 of the lighting device 26 of the calculated main light emission amount, rotates the quick return mirror 11 to the solid line position, and instructs the lighting device 26 at the timing of exposure for photography. The main light emission is performed with the amount of light emitted.

次に、図２、３に基づき、本実施形態における制御を示す。
図２は本実施形態における各部の動作タイミングを示した図である。
図３はカメラ制御部３０の動作を示すフローチャートである。 Next, the control in this embodiment is shown based on FIGS. 2 and 3.
FIG. 2 is a diagram showing the operation timing of each part in the present embodiment.
FIG. 3 is a flowchart showing the operation of the camera control unit 30.

まず、カメラ制御部３０は、レリーズスイッチ２０を介して撮影指示が入力されると（図２のｔ１，図３のステップＳ０１，ＹＥＳ）と、所定の発光量の第１予備発光を照明装置２６に指示する。この指示により照明装置２６は第１予備発光を行う（図２のｔ２，図３のステップＳ０２）。 First, when a shooting instruction is input via the release switch 20 (t1 in FIG. 2 and steps S01 and YES in FIG. 3), the camera control unit 30 emits a predetermined amount of first preliminary light emission to the lighting device 26. To instruct. According to this instruction, the lighting device 26 performs the first preliminary light emission (t2 in FIG. 2 and step S02 in FIG. 3).

カメラ制御部３０は、第１予備発光のタイミングで、測光センサ１９にて露光を行い、第１予備発光を行った際の被写体からの反射光量を算出（測光演算）する（ステップＳ０３）。 The camera control unit 30 performs exposure with the photometric sensor 19 at the timing of the first preliminary light emission, and calculates the amount of reflected light from the subject when the first preliminary light emission is performed (photometric calculation) (step S03).

次いで、第１予備発光による反射光量が本発光の発光量を決定するのに十分であったか、即ち第２予備発光が必要かどうかを判定する（ステップＳ０４）。
第２予備発光が不要な場合（ステップＳ０４，ＮＯ）はステップＳ０７へ進み、第２予備発光が必要な場合（ステップＳ０４，ＹＥＳ）はステップＳ０５へ進む。
なお、第２予備発光は、第１予備発光よりも強い発光量で行うものであり、第１予備発光において被写体からの反射光が十分な測光に不十分だった場合に、より強い第２予備発光を行うものである。 Next, it is determined whether the amount of reflected light from the first preliminary emission is sufficient to determine the emission amount of the main emission, that is, whether the second preliminary emission is necessary (step S04).
If the second preliminary light emission is not required (steps S04, NO), the process proceeds to step S07, and if the second preliminary light emission is required (steps S04, YES), the process proceeds to step S05.
The second preliminary emission is performed with a stronger emission amount than the first preliminary emission, and when the reflected light from the subject is insufficient for sufficient photometry in the first preliminary emission, a stronger second preliminary emission is performed. It emits light.

カメラ制御部３０は、第２予備発光が必要であると判断した場合（ステップＳ０４，ＹＥＳ）、照明装置２６に第２発光量を指示し、第２予備発光を行わせる（図２のｔ３，図３のステップＳ０５）。
第２予備発光のタイミングで測光センサ１９にて露光を行い、第２予備発光を行った際の被写体からの反射光量を算出（測光演算）する（ステップＳ０６）。
そして、第２予備発光の反射光量から本発光量を決定し、決定した本発光量を照明装置２６に通知し、撮影タイミングにて本発光を指示（図２のｔ４，図３のステップＳ０７）することで、１枚目の撮影が終了する。 When the camera control unit 30 determines that the second preliminary light emission is necessary (step S04, YES), the camera control unit 30 instructs the lighting device 26 to perform the second preliminary light emission (t3 in FIG. 2). Step S05 in FIG. 3).
Exposure is performed by the photometric sensor 19 at the timing of the second preliminary light emission, and the amount of reflected light from the subject when the second preliminary light emission is performed is calculated (photometric calculation) (step S06).
Then, the main light emission amount is determined from the reflected light amount of the second preliminary light emission, the determined main light emission amount is notified to the lighting device 26, and the main light emission is instructed at the shooting timing (t4 in FIG. 2, step S07 in FIG. 3). By doing so, the first shooting is completed.

一方、ステップＳ０４において第２予備発光は不要と判断した場合は、第１予備発光の反射光量から本発光量を決定し、決定した本発光量を照明装置２６に通知し、撮影タイミングにて本発光を指示（ステップＳ０７）することで、１枚目の撮影が終了する。 On the other hand, when it is determined in step S04 that the second preliminary light emission is unnecessary, the main light emission amount is determined from the reflected light amount of the first preliminary light emission, the determined main light emission amount is notified to the lighting device 26, and the main light emission amount is notified at the shooting timing. By instructing the light emission (step S07), the shooting of the first image is completed.

ステップＳ０７のあと、所定時間内に次の撮影指示がない場合（ステップＳ０８，ＮＯ）、終了する。
ステップＳ０７のあと、所定時間内に次の撮影指示があった場合（ステップＳ０８，ＹＥＳ）、連写中か否かを判定する（ステップＳ０９）。 After step S07, if there is no next shooting instruction within a predetermined time (step S08, NO), the process ends.
When the next shooting instruction is given within a predetermined time after step S07 (step S08, YES), it is determined whether or not continuous shooting is in progress (step S09).

連写中であると判定した場合（ステップＳ９，ＹＥＳ）は、前回の撮影時に本発光量を決定するのに使用した予備発光が、第１予備発光か第２予備発光のどちらであったかを判断する（ステップＳ１０） When it is determined that continuous shooting is in progress (steps S9, YES), it is determined whether the preliminary emission used to determine the main emission amount at the time of the previous shooting was the first preliminary emission or the second preliminary emission. (Step S10)

前回、第２予備発光にて本発光量を決定した場合（ステップＳ１０，第２予備発光）、第２予備発光を行うように照明装置２６に指示を送る（図２のｔ５，図３のステップＳ１１）。
そして、第２予備発光の発光タイミングにて測光センサ１９にて露光を行い、第２予備発光を行った際の被写体からの反射光量を算出（測光演算）する（ステップＳ１２）。 When the main emission amount was determined by the second preliminary emission last time (step S10, second preliminary emission), an instruction is sent to the lighting device 26 to perform the second preliminary emission (steps t5 in FIG. 2 and step 3 in FIG. 3). S11).
Then, exposure is performed by the photometric sensor 19 at the emission timing of the second preliminary emission, and the amount of reflected light from the subject when the second preliminary emission is performed is calculated (photometric calculation) (step S12).

次いで、第２予備発光による反射光量が本発光の発光量を決定するのに十分であったか、即ち第１予備発光が必要かどうかを判定する（ステップＳ１３）。
第１予備発光が不要な場合（ステップＳ１３，ＮＯ）はステップＳ１６へ進む。
第１予備発光が必要な場合（ステップＳ１３，ＹＥＳ）はステップＳ１４へ進む。
なお、第１予備発光は、第２予備発光よりも弱い発光量で行うものであり、第２予備発光において被写体からの反射光が明るすぎる場合に、弱い第１予備発光を行うものである。 Next, it is determined whether the amount of reflected light from the second preliminary emission is sufficient to determine the emission amount of the main emission, that is, whether the first preliminary emission is necessary (step S13).
If the first preliminary light emission is unnecessary (steps S13, NO), the process proceeds to step S16.
When the first preliminary light emission is required (step S13, YES), the process proceeds to step S14.
The first preliminary light emission is performed with a light emission amount weaker than that of the second preliminary light emission, and when the reflected light from the subject is too bright in the second preliminary light emission, the weak first preliminary light emission is performed.

カメラ制御部３０は、第１予備発光が不要であると判断した場合（ステップＳ１３，ＮＯ）、第２予備発光の反射光量から本発光量を決定し、決定した本発光量を照明装置２６に通知し、撮影タイミングにて本発光を指示（図２のｔ６，図３のステップＳ１６）することで、２枚目の撮影が終了する。 When the camera control unit 30 determines that the first preliminary light emission is unnecessary (steps S13, NO), the camera control unit 30 determines the main light emission amount from the reflected light amount of the second preliminary light emission, and determines the main light emission amount to the lighting device 26. By notifying and instructing the main light emission at the shooting timing (t6 in FIG. 2, step S16 in FIG. 3), the second shooting is completed.

カメラ制御部３０は、第１予備発光が必要であると判断した場合（ステップＳ１３，ＹＥＳ）、照明装置２６に第１発光量を指示し、第１予備発光を行わせる（ステップＳ１４）。
第１予備発光のタイミングで、測光センサ１９にて露光を行い、第１予備発光を行った際の被写体からの反射光量を算出（測光演算）する（ステップＳ１５）。
そして、第１予備発光の反射光量から本発光量を決定し、決定した本発光量を照明装置２６に通知し、撮影タイミングにて本発光を指示（ステップＳ１６）することで、２枚目の撮影が終了する。 When the camera control unit 30 determines that the first preliminary light emission is necessary (step S13, YES), the camera control unit 30 instructs the lighting device 26 to perform the first preliminary light emission (step S14).
Exposure is performed by the photometric sensor 19 at the timing of the first preliminary light emission, and the amount of reflected light from the subject when the first preliminary light emission is performed is calculated (photometric calculation) (step S15).
Then, the main light emission amount is determined from the reflected light amount of the first preliminary light emission, the determined main light emission amount is notified to the lighting device 26, and the main light emission is instructed at the shooting timing (step S16). Shooting ends.

ステップＳ０９で連写中でないと判断した場合（ステップＳ９，ＮＯ）、及び前回、第１予備発光にて本発光量を決定した場合（ステップＳ１０，第１予備発光）、１枚目の撮影同様、第１予備発光を照明装置２６に指示する（ステップＳ１７）。 When it is determined in step S09 that continuous shooting is not in progress (step S9, NO), and when the main light emission amount is determined by the first preliminary light emission last time (step S10, first preliminary light emission), the same as the first shooting. , The first preliminary light emission is instructed to the lighting device 26 (step S17).

カメラ制御部３０は、第１予備発光のタイミングで、測光センサ１９にて露光を行い、第１予備発光を行った際の被写体からの反射光量を算出（測光演算）する（ステップＳ１８）。
次いで、第１予備発光による反射光量が本発光の発光量を決定するのに十分であったか、即ち第２予備発光が必要かどうかを判定する（ステップＳ１９）。
第２予備発光が不要な場合（ステップＳ１９，ＮＯ）はステップＳ２２へ進み、第２予備発光が必要な場合（ステップＳ１９，ＹＥＳ）はステップＳ２０へ進む。 The camera control unit 30 performs exposure with the photometric sensor 19 at the timing of the first preliminary light emission, and calculates the amount of reflected light from the subject when the first preliminary light emission is performed (photometric calculation) (step S18).
Next, it is determined whether the amount of reflected light from the first preliminary emission is sufficient to determine the emission amount of the main emission, that is, whether the second preliminary emission is necessary (step S19).
If the second preliminary light emission is not required (steps S19, NO), the process proceeds to step S22, and if the second preliminary light emission is required (steps S19, YES), the process proceeds to step S20.

カメラ制御部３０は、第２予備発光が必要であると判断した場合（ステップＳ２０，ＹＥＳ）、照明装置２６に第２予備発光用を指示し、第２予備発光を行わせる（ステップＳ２０）。
第２予備発光のタイミングで、測光センサ１９にて露光を行い、第２予備発光を行った際の被写体からの反射光量を算出（測光演算）する（ステップＳ２１）。
そして、第２予備発光の反射光量から本発光量を決定し、決定した本発光量を照明装置２６に通知し、撮影タイミングにて本発光を指示（ステップＳ２２）することで、２枚目の撮影が終了する。 When the camera control unit 30 determines that the second preliminary light emission is necessary (step S20, YES), the camera control unit 30 instructs the lighting device 26 to perform the second preliminary light emission (step S20).
Exposure is performed by the photometric sensor 19 at the timing of the second preliminary light emission, and the amount of reflected light from the subject when the second preliminary light emission is performed is calculated (photometric calculation) (step S21).

一方、ステップＳ１９において第２予備発光は不要と判断した場合は、第１予備発光の反射光量から本発光量を決定し、決定した本発光量を照明装置２６に通知し、撮影タイミングにて本発光を指示（ステップＳ２２）することで、２枚目の撮影が終了する。 On the other hand, when it is determined in step S19 that the second preliminary light emission is unnecessary, the main light emission amount is determined from the reflected light amount of the first preliminary light emission, the determined main light emission amount is notified to the lighting device 26, and the main light emission amount is notified at the shooting timing. By instructing the light emission (step S22), the second shooting is completed.

図２のｔ７は３回目の撮影におけるＳ１１，ｔ８はＳ１３，ｔ９はＳ１６の場合に対応している。 After steps S16 and 22, the process returns to step S08, and if there is no next shooting instruction within a predetermined time (steps S08, NO), the process ends.
If the next shooting instruction is given within a predetermined time after step S07 (step S08, YES), the above-mentioned step S09 and subsequent steps are repeated.
In FIG. 2, t7 corresponds to the case of S11 in the third shooting, t8 corresponds to the case of S13, and t9 corresponds to the case of S16.

以上、本実施形態によると、連写撮影時など、前回撮影したときと同じような撮影状況の場合において、前回行った予備発光をまず行い、その結果が良好であれば他の予備発光は行わない。したがって、不要な場合に複数回の予備発光を行うことがなく、レリーズタイムラグの少ない撮影を行うことができる。 As described above, according to the present embodiment, in the case of shooting conditions similar to those of the previous shooting, such as during continuous shooting, the preliminary light emission performed last time is first performed, and if the result is good, other preliminary light emission is performed. not.
