Abstract:
PCT No. PCT/US81/00469 Sec. 371 Date Oct. 7, 1981 Sec. 102(e) Date Oct. 7, 1981 PCT Filed Apr. 10, 1981 PCT Pub. No. WO82/03741 PCT Pub. Date Oct. 28, 1982.A system for spatially transforming images by separate transformation of each dimension of the image is exemplified by a raster scan television system which includes for each color component a transposing memory providing a change of scan direction from horizontal to vertical, a vertical transformation system transforming in the vertical direction the vertically scanned video information, a second transposing memory coupled to receive vertically transformed video information and provide a change of scan direction from vertical back to horizontal, and a horizontal transformation system coupled to horizontally transform the horizontally scanned video signal to produce a color component output signal. The transformation system is controlled by a transform composer factorizor which receive input commands designating X and Y pretranslations, X and Y size control, Z axis rotation angles, and X and Y post translations to produce a commanded composite transformation which is then factored into horizontal and vertical components.
