ABSTRACT:
An electronic still camera an image-forming optical system for forming an image of an object, image pick-up for converting the image into an electrical signal, a first electric motor, a second electric motor, blocking device for allowing and blocking the light forming the image from reaching the image pick-up, the blocking device being driven by the second motor and a rotary member rotated at a uniform speed by the first motor, the rotary member having plural areas in each of which areas one frame amount of the electrical signal corresponding to a still image of the formed image is to be recorded. The camera further comprises recording device for recording the one frame amount of electrical signal in one of the plural areas of the rotary member during rotation, the recording device being moved by the second motor in such manner as to enable the recording device to shift from one to another of the plural areas for recording.
