Abstract
Reading horizontal and vertical scanning circuits and a resetting vertical scanning circuit are connected to an image sensor including a plurality of photodiodes arranged in a matrix form. The resetting vertical scanning circuit generates vertical scanning pulses prior to the scanning of the reading vertical scanning circuit by a shutter time T.sub.S. Where the reading vertical scanning circuit performs a two-line-at-a-time reading, the resetting vertical scanning circuit also performs the two-line-at-a-time reading. The reading vertical scanning circuit reads the signal of the lines reset by the resetting scanning circuit and outputs it as a video signal.
