High resolution image storage whereby image is divided and stored as plural groups of horizontally and vertically interleavable data

摘要

The system comprises a memory formed of several disk stores for storing data representing at least one image and a working framestore for temporarily storing one or two frames of image data. Data in the framestore is modified by a processor under operator control. Data is stored in the disk stores by switching selected pixels from each line and selected lines from the or each frame, by way of switches and buffers, to respective disk stores such that the image data is divided into groups which each define a lower resolution version of the whole image frame.
