Abstract:
An image pickup device provided with an automatic exposure function includes an image pickup unit configured to input image data corresponding to a subject, a face detection unit configured to detect a human face from the image data input from the image pickup unit, a photometric unit configured to measure optical intensity, designating the human face detected by the face detection unit as a photometric area, and an exposure control unit configured to calculate the exposure based on the photometric result of the human face by the photometric unit, and to perform exposure control based on the calculated exposure.
