Description
背面検知部316は、赤外LEDと検知センサがモジュール化された構成となっており、物体等が近接した場合に赤外光が物体に反射され、検知センサでの受光量によって物体を検知できるようになっている。なお、所定の検知範囲内の物体を検知することができる構成であれば、赤外LEDと受光部以外の公知の構成、例えば、照度センサや静電センサ等を用いた構成を背面検知部としてよい。また、物体までの距離を測定するセンサも、測定した距離から物体が所定の検知範囲内にあるか否かがわかるので、所定の検知範囲内にある物体を検知するためのセンサに含まれる。物体までの距離を測定するセンサを用いる場合、センサの測定結果(センサの出力)に基づいて、所定の検知範囲内に物体を検知しているか否かを判定すればよい。背面検知部316の配置については図3を用いて後述する。 The back surface detection unit 316 has a configuration in which an infrared LED and a detection sensor are modularized. When an object or the like approaches, the infrared light is reflected by the object, and the object can be detected by the amount of light received by the detection sensor. It is like that. In addition, if it is the structure which can detect the object in a predetermined detection range, well-known structures other than infrared LED and a light-receiving part, for example, the structure using an illuminance sensor, an electrostatic sensor, etc. as a back surface detection part. Good. A sensor for measuring the distance to the object is also included in the sensor for detecting an object within the predetermined detection range because it can be determined from the measured distance whether the object is within the predetermined detection range. When a sensor that measures the distance to an object is used, it may be determined based on the sensor measurement result (sensor output) whether or not the object is detected within a predetermined detection range . The arrangement of the rear sensing unit 316 will be described later with reference to FIG.
次に、オートバウンス発光撮影に係るストロボ装置300の発光に伴う処理を図4〜図8を用いて説明する。なお、図4〜図8では、バウンス発光撮影時の反射面として天井を用いる場合について説明する。 Next, processing in response to light emission of the flash device 300 according to the auto bounce flash photography will be described with reference to FIGS. 4-8. 4 to 8, the case where a ceiling is used as a reflection surface at the time of bounce flash photography will be described.
ステップS410にてストロボマイコン310は、天井距離に関する情報を取得するために放電管305を発光させるときの可動部300bの回動角度を決定するため、姿勢検出回路360の検出結果に基づいて本体部300aの姿勢を判別する。姿勢検出回路360の検出結果をストロボマイコン310の内蔵メモリに格納し、横位置状態か縦位置状態かを判別する。横位置状態であればステップS411へ移行し、縦位置状態であればステップS412へ移行する。なお、カメラ本体100にストロボ装置300を装着している状態では、カメラ本体100の姿勢と本体部300aの姿勢は対応関係にあるので、姿勢検出回路360の検出結果ではなく姿勢検出回路140の検出結果を用いてもよい。また、カメラ本体100にストロボ装置300を装着している状態では、カメラ本体100の姿勢が検出できれば本体部300aの姿勢を判別できるため、ストロボ装置300に姿勢検出回路を設けていなくてもよい。 In step S410, the stroboscopic microcomputer 310 determines the rotation angle of the movable part 300b when the discharge tube 305 is caused to emit light in order to acquire information relating to the ceiling distance, and thus the main body part based on the detection result of the attitude detection circuit 360. The posture of 300a is determined. The detection result of the posture detection circuit 360 is stored in the built-in memory of the flash microcomputer 310, and it is determined whether it is in the horizontal position state or the vertical position state. If the lateral position state proceeds to step S411, if the vertical position state proceeds to step S412. Note that when the strobe device 300 is attached to the camera main body 100, the posture of the camera main body 100 and the posture of the main body portion 300a are in a corresponding relationship, and therefore the detection of the posture detection circuit 140, not the detection result of the posture detection circuit 360. Results may be used. Further, when the strobe device 300 is mounted on the camera body 100, the posture of the main body 300a can be determined if the posture of the camera body 100 can be detected. Therefore, the strobe device 300 may not be provided with the posture detection circuit.
ステップS411にてストロボマイコン310は、天井距離に関する情報を取得するために放電管305を発光させるときの可動部300bの回動角度を決定する制御として横位置角度制御を適用する。横位置角度制御が適用されると、横位置角度制御が適用されたことを示す情報をストロボマイコン310の内蔵メモリに格納し、天井距離に関する情報を取得するためにバウンス駆動回路340dを用いて可動部300bを上方向に回動させる。なお、バウンス駆動回路340dを用いて可動部300bを上方向に回動させる処理など横位置角度制御が適用される処理は、後述するステップS419以降に行われる。横位置角度制御適用後、ステップS413へ移行する。 In step S411, the stroboscopic microcomputer 310 applies lateral position angle control as control for determining the rotation angle of the movable part 300b when the discharge tube 305 is caused to emit light in order to acquire information related to the ceiling distance. When the lateral position angle control is applied, information indicating that the lateral position angle control is applied is stored in the built-in memory of the stroboscopic microcomputer 310, and is movable using the bounce drive circuit 340d to obtain information on the ceiling distance. the part 300 b is rotated upward. The processing lateral position angle control processing such pivoting the movable portion 300 b in the upper direction using the bounce driving circuit 340d is applied, is performed after step S419 to be described later. After the lateral position angle control is applied, the process proceeds to step S413.
ステップS412にてストロボマイコン310は、天井距離に関する情報を取得するために放電管305を発光させるときの可動部300bの回動角度を決定する制御として縦位置角度制御を適用する。縦位置角度制御が適用されると、縦位置角度制御が適用されたことを示す情報をストロボマイコン310の内蔵メモリに格納し、天井距離に関する情報を取得するためにバウンス駆動回路340bを用いて可動部300bを左方向または右方向に回動させる。なお、バウンス駆動回路340bを用いて可動部300bを左方向と右方向のどちらに回動させるかは、左縦位置状態か右縦位置状態に応じて決定される。 In step S412, the stroboscopic microcomputer 310 applies vertical position angle control as control for determining the rotation angle of the movable portion 300b when the discharge tube 305 is caused to emit light in order to acquire information related to the ceiling distance. When the vertical position angle control is applied, information indicating that the vertical position angle control is applied is stored in the built-in memory of the flash microcomputer 310, and is movable using the bounce drive circuit 340b to obtain information on the ceiling distance. rotating the part 300 b in the left or right. Incidentally, by using the bounce driving circuit 340b may either rotate in either the movable portion 300 b of the left and right directions are determined in accordance with the left vertical position state or the right vertical position state.
また、バウンス駆動回路340dを用いて可動部300bを左方向または右方向に回動させる処理など縦位置角度制御が適用される処理は、後述するステップS419以降に行われる。縦位置角度制御適用後、ステップS413へ移行する。 The processing of the vertical position angle control processing such pivoting the movable portion 300 b in the left or right using the bounce driving circuit 340d is applied, is performed after step S419 to be described later. After applying the vertical position angle control, the process proceeds to step S413.
ステップS419にてストロボマイコン310は、バウンス回路340を用いて発光部の照射方向が天井方向となるように可動部300bを回動させる。その後、ステップS420へ移行する。 In step S419, the stroboscopic microcomputer 310 uses the bounce circuit 340 to rotate the movable unit 300b so that the irradiation direction of the light emitting unit is the ceiling direction. Thereafter, the process proceeds to step S420.
