Abstract
A picture image zoom apparatus is provided which includes an area specifying unit which designates a predetermined area of the displayed picture image for magnification. The specified area is displayed on the display unit (which displays the overall video signal from the camera circuit) in a manner so as to be distinguishable from the other areas of the picture image. The video signal is produced from the camera circuit and written in a picture image memory. As a result, the video signal is sequentially read from the image memory, and the portion of the video signal corresponding to the predetermined area of the image is displayed on the display unit in a magnified form.
