Disclosed is an automatic exposure control apparatus so adapted that a photographic subject such as a human being can be photographed appropriately even if the subject is backlighted or excessively front-lighted. The control apparatus divides a frame into a plurality of areas and detects the backlighted state or excessively front-lighted state based upon the luminance of each of these areas. In case of backlighting or excessive front-lighting, an exposure correction of the entire frame is performed in conformity with the luminance of an area in which a flesh color is present in the vicinity of the center of the frame.
