記載の電子スチルカメラ。[Claims for Utility Model Registration] (1) An electronic still camera equipped with an electronic shutter function that controls the actual light reception time of the sensor of a fixed image sensor by controlling the opening/closing timing of the overflow drain or readout gate of the solid-state image sensor. An electronic still camera characterized in that the actual start and end of light reception is performed in synchronization with a pulse that is a countdown of a primary oscillation clock pulse generated from a primary oscillator inside the electronic still camera. (2) The electronic still camera according to claim 1 of the utility model registration, characterized in that a horizontal synchronization signal is a pulse obtained by counting down the original oscillation clock pulse in which the start and end of light reception are performed synchronously. .
