In an image signal processor ( 1 ), a camera operation estimating part ( 3 ) detects a movement vector of an input image to estimate, for instance, a panning operation in a horizontal direction, a tilting operation in a vertical direction, a zooming operation such as a zooming-in, a zooming-out, or the like from the movement vector. An image output part ( 5 ) reads an important image signal before and after a camera operation from image signals stored in an image storage memory ( 4 ), and outputs and displays the important image signal on a display means. Further, when there is a plurality of display means, an image before and after the camera operation and an image that is currently broadcast are displayed on the separate display means.
