ABSTRACT:
An image crop circuit performs a crop process for an input video image under the control of a CPU. An image shape changing circuit performs an image shape changing process such a mosaic process for a video signal that is cropped corresponding to a control signal. The image shape changing circuit supplies the video image to a graphic inserter circuit. A GDC that is a graphic dedicated CPU draws a positive region of a contour line of the crop region as a solid line and a negative region as a dotted line. The graphic inserter circuit superimposes the contour line with the video signal that is cropped and outputs the resultant signal to both a CRT monitor and an output terminal.
