Abstract
An electronic photographic camera includes an imaging optical system operable to be focused to an object to be photographed, a solid state imaging sensing device including a plurality of light-receiving elements disposed in the imaging plane of the imaging optical system and capable of producing a charge corresponding to the quantity of incident light and accumulating the charge therein, first transfer means having a first output terminal and adapted to transfer the charge accumulated in each of the elements separately to the first output terminal, and second transfer means having a second output terminal and adapted to transfer the charges produced in some or all of the elements collectively to the second output terminal, and metering means for measuring the brightness of the object from the charge transferred by the second transfer means.
