Abstract
In an automatic exposure control device of digital information type for a single lens reflex camera, a sampling circuit for dividing pulses generated from an oscillator and a shutter release signal generating circuit are connected with a gate means having a function of an AND circuit. The gate means connected with a leading shutter blind control device and a normally turned OFF gate interposed between the oscillator and a clock pulse counter. When the gate means is turned ON by the simultaneous output of the sampling circuit and the shutter release signal generating circuit, the normally turned OFF gate is turned ON to initiate the counting of the clock pulses and the leading shutter blind is started to initiate exposure.
