We developed an image-handling system for super-high-resolution images of 3840 x 2070 pixels. In this system, each image is divided into four images using a selection circuit that subsamples in the horizontal and vertical directions. The circuit is placed between the CPU data bus and the frame memory, and the images are distributed to four HDTV frame memories. This allows the CPU to handle one continuous image space, and also permits the use of HDTV techniques and equipment in system construction. We also developed a motion-picture production system using this system, and evaluated the overall spatial frequency characteristics of a 35mm motion picture. Resolution of more than 1600 TV-lines was obtained from an 8-perforation per frame negative film.
