Abstract

An exposure control device for an electronic photographing apparatus comprises a gate circuit, which can transfer a transfer gate driving signal to a transfer gate in synchronism to the horizontal vertical synchronization control of said solid state image sensor, and a shutter driving circuit, which can operate a shutter in synchronism with a transfer gate driving signal first generated after the appearance of a shutter release signal. While the shutter is open, the gate circuit inhibits the transfer gate driving signal.
