    摘要： An imaging signal obtained from CCD is supplied to the pre-processing circuit to form the pre-processing signal consisting of a luminance signal and a color signal and the pre-processing signal is supplied in turn to the post-processing circuit to form the post-processing signal to be outputted to the external circuit or to be recorded. The circuits from CCD to pre-processing circuit are driven by the first clock CKH or the second clock which is slower than the first clock, while the post-processing circuit is driven by the first clock. A clock exchange circuit is provided between the pre-processing circuit and the post-processing circuit, and when the circuits up to the pre-processing circuit are driven by the second clock, the clock exchange circuit is operated to supply the pre-processing signal exchanged to the first clock from the second clock is supplied to the post-processing circuit. Thereby, the post-processing circuit can used in common.

    摘要： A video signal follow-up processing system for adaptively tracking to the moving of a subject. A detection feature pattern is formed through acquisition of brightness and hue frequency characteristic data based on pixel information in a detection measurement frame, a similarity calculation method, which can distinguish a reference measurement frame from other areas, is selected on the screen, and the position of a detection measurement frame with a feature pattern having the highest similarity with the standard feature pattern obtained from the reference measurement frame is determined, in order to change and control an image to be projected on the display screen based on the positional information of the detection measurement frame, so that the video signal follow-up processing system can adaptively track to the moving of the subject.
