摘要:
A solid-state imaging device for imaging an object moving at a high speed using a solid-state image sensor having an electronic shutter function. A modulated horizontal synchronizing signal, modulated so as to have a frequency higher than the frequency of the normal horizontal synchronizing signal depending on the designated shutter speed, is supplied from a modulated synchronizing signal generator to a timing generator. The timing generator counts a predetermined number of the modulated horizontal synchronizing signal pulses since the timing of a vertical synchronizing signal to output a readout pulse at a more prompt timing than when the normal horizontal synchronizing signal pulses are counted. The readout pulse controls the function of the electronic shutter of the solid-state imaging device. This enables the CCD image sensor to perform imaging by a high-speed shutter operation.
