摘要： An exposure control apparatus for controlling an exposure adjustment mechanism on the basis of a captured image signal includes the following elements. A face detecting unit detects a face of a person appearing in a captured image on the basis of the captured image signal. A histogram data determining unit determines histogram data by setting a face detection region in the captured image according to detection information and detecting at least a brightness value of the face detection region from the captured image signal. A target brightness setting unit sets a target brightness range for desired brightness of the face. An exposure control amount determining unit determines, when a face is detected, an amount of control for the exposure adjustment mechanism by comparing the target brightness range with a brightness value at a peak of the histogram data or a brightness region in the vicinity of the peak.
