Title: Generating partial TV image of overall picture
IPC: H04N9/12
Filed: 1980-05-12
Abstract: An overall large field of view image is viewed by a smaller field of view TV camera and thereby divided into a plurality of individual images EBI to EBVIII. The individual image signals after being digitized, and possibly via a mass store M.S.P., are stored in respective stores B1 to Bm. B1 to Bm can be strobed in synchronism by a clock generator TG, and information from B1 to Bm is passed through selective delay means VZ1 to VZm, which introduce no delay or a line return time delay, to lines 1 to 4. A set of switches ES1 connect first the delayed output from Bx and then the undelayed output from B(x + 1) to a monitor M1 via a digital-to-analog converter DA1. The scanning of M1 is suitably delayed relative to the strobing of B1 to Bm, to give a partial image, of size equal to the individual images, which can be selected from anywhere inside the overall image. The individual images in B1 to Bm can be processed by a computer to correct for geometric and grey scale distortion in the TV camera, using iterative comparisons with a reference partial image EB REF. <IMAGE>
