Abstract
Abstract @ In an electronic still camera, a solid-state imaging element (34) and a photosensitive film (18) which receive an object image are arranged on the optical path of an optical lens system (2, 16, 24, 25). The object image is simultaneously formed on the solid-state imaging element (34) and the photosensitive film (18) upon depression of a shutter switch (6).
