Abstract
In an image sensing apparatus having a solid-state image sensor provided with an antiblooming gate and an electronic flash device, a clock signal generating circuit is arranged to apply to the gate a clock signal at a given frequency during the flashing period of the flash device and at a lower frequency than the given frequency during a period immediately before the flashing period and a period after completion of flashing by the flash device. The device includes a rotary encloder with light transmitting, blocking and semi-transmitting sections. The position of the encoder is used in an exposure means for controlling an exposure condition of a photoconverting member.
