ABSTRACT:
An electronic shutter control system provided with an imaging device, a driving circuit to drive and control the imaging device and an exposure control circuit to output a signal to the drive circuit. The shutter opens in synchronization with a signal to read out electric charge in a photoelectric converter section to a vertical transfer section. The vertical transfer section is held in a state enabling readout of the signal after cleaning out an unnecessary electric charge. As a result, an electric charge is read out simultaneously with the close of the shutter. According to an electronic shutter controlling method, fast reverse transfer is stopped at a level of the proper exposure less the predetermined amount and an electric charge signal is read out to the vertical transfer section, waiting for the potential of the vertical transfer section to achieve a state wherein it can receive the electric charge signal.
