Description

上記目的を達成するために、本発明の撮像装置は、発光手段と、画像データから被写体の顔領域を検出する検出手段と、前記発光手段を発光させていない画像データから被写体の顔領域が検出されない場合、前記発光手段を発光させた画像データから被写体の顔領域が検出される第１領域を推定する推定手段と、推定された前記第１領域に複数の枠を設定する設定手段と、前記発光手段を発光させていない画像データに対して設定された前記複数の枠の信号値に基づいて調光を行う調光手段と、を備えることを特徴とする。 In order to achieve the above object, the image pickup apparatus of the present invention detects the face area of the subject from the light emitting means, the detecting means for detecting the face area of the subject from the image data, and the image data in which the light emitting means is not emitted. If not, the estimation means the face area of the subject from the image data obtained by emitting the light emitting means to estimate a first region that will be detected, and setting means for setting a plurality of frames of the estimated first regions, wherein It is characterized by comprising a dimming means for performing dimming based on the signal values of the plurality of frames set for the image data in which the light emitting means is not emitting light.
