DEVICE FOR PICKING UP IMAGE AND FOR PROCESSING DIGITAL SIGNAL

摘要

A solid-state image pickup device (11) is driven by a driving circuit (12), synchronizing with a synchronizing signal generated by a generating circuit (13). The solid-state image pickup device (11) outputs a signal at the time earlier by a period TA than the end time of a horizontal blanking period. This signal is outputted as a video signal after being processed in a signal processing circuit (14). While at this time, the video signal is delayed by the period of (TB-TA) comparing with the synchronizing signal because of the signal processing, the synchronizing signal can be outputted at the same timing as that of the video signal by delaying it with a delay circuit (15) by the period equal to the remainder obtained by substracting the period of TA from the delay time TB of the signal processing circuit (14). Further, the size of the circuit configuration can be reduced by incorporating the delay circuit (15) in the LSI constituting the signal processing circuit (14) and the interference of the synchronizing signal with the video signal can be decreased very much.
