ABSTRACT:
An exposure control device for a still video camera having an imaging device provided with shutter function, a flash device for emitting light, and a light metering device for obtaining brightness information of an object for exposure control or a distance metering device for obtaining information of an object distance, is adapted for actuating the flash to emit during the accumulation time of signal charges in the imaging device, sweeping unnecessary charges out from a transfer section of the imaging device when the flash emitting is completed, and transferring the accumulated signal charges to the transfer section, whereby smear factor of the image signal can be eliminated. The flash is emitted when the accumulation of signal charges starts and the flash stops emitting when the proper exposure is attained. The emitting time is determined by the object distance, thereby the flash emission contributes to a proper exposure.
