IMAGE SIGNAL PROCESSING DEVICE AND METHOD, AND IMAGE SIGNAL PROCESSING SYSTEM

摘要

In an image signal processing device (1), a camera operation estimating part (3) detects the motion vectors of input images and estimates, from the motion vectors, for example horizontal and vertical pan operations, tilt operations or zoom operations such as zoom-in and zoom-out. An image output part (5) reads and outputs, from image signals stored in an image storage memory (4), critical image signals produced before and after a camera operation, and causes display means to display those critical image signals. If there exist a plurality of display means, they may be used to separately display the images produced before and after a camera operation and the images currently being broadcast.
