Abstract
A video signal, which is obtained from a solid-state electronic image sensing device, is used to obtain a photometric value corresponding to the environment in which a subject is present. Photometric areas that differ for every field in one frame are set within a photographic area of a CCD. A luminance-signal component extracted from the video signal by a Y.sub.L synthesizing circuit is integrated by an integrating circuit, under the control of a CPU, with respect to a horizontal scanning interval and vertical scanning interval corresponding to the photometric area. Obtained integrated values are added field by field and a photometric value is calculated field by field from the value resulting from adding the integrated values.
