Abstract:
1. A video signal processing apparatus which generates a video signal in a prescribed format by capturing output of a solid-state imaging element that is driven by corresponding to each timing of horizontal scanning and vertical scanning, said processing apparatus comprising: a first signal processing circuit for generating a first video signal by performing first signal processing on an analog video signal that is continuously outputted from said solid-state imaging element by a horizontal-line unit; an A/D converter circuit for generating first video data by converting said first video signal to digital information; a memory circuit which stores said first video data at least by one horizontal-line unit, and reads out said first video data with a delay of a prescribed delay period; and a second signal processing circuit for generating second video data by performing second signal processing on said first video data that is read out from said memory circuit; a first control circuit for changing an operating frequency of said second signal processing circuit; wherein said first control circuit is configured to increase said operating frequency of said second signal processing circuit in a second signal processing period so that said second signal processing is completed within an interval period between processing periods of said analog video signal.
