| description | To provide an imaging device that improves a detection accuracy of a face area upon multi-flash unit photographing, and can suppress a release time lag, and to provide a light emission control method and program of the imaging device.SOLUTION: A camera 100 is configured to: sequentially perform pre-light emission with respect to a plurality of slave flash units, acquire photographing images during the pre-light emission and acquire a coordinate of a focused rang-finding frame; select at least one of the plurality of slave flash units on the basis of a light measurement result of reflection light from a subject using the photographing image during the pre-light emission, and the acquired coordinate of the focused range-finding frame; perform the pre-light emission by the at least selected one slave flash unit at a time, and acquire photographing images during the additional pre-light emission; and, when a face area of a subject is detected using the photographing image during the additional pre-light emission, calculate an amount of light emission specialized in the detected face area upon main light emission with respect to the plurality of slave flash units.SELECTED DRAWING: Figure 4
【課題】多灯ストロボ撮影時の顔領域の検出精度が向上し、且つレリーズタイムラグを抑えることができる撮像装置及びその発光制御方法並びにプログラムを提供する。【解決手段】カメラ１００は、複数のスレーブストロボに対して順にプリ発光を行い、プリ発光中の撮像画像を取得すると共に合焦した測距枠の座標を取得する。プリ発光中の撮像画像を用いた前記被写体からの反射光の測光結果及び取得した合焦した測距枠の座標に基づき、複数のスレーブストロボのうち少なくとも１つを選定し、選定された少なくとも１つのスレーブストロボにより一斉にプリ発光を行って、追加プリ発光中の撮像画像を取得する。追加プリ発光中の撮像画像を用いて被写体の顔領域が検出された場合、複数のスレーブストロボに対して、検出された顔領域に特化したメイン発光の際の発光量を算出する。【選択図】図４ |
