ABSTRACT:
An image processing system and a method for manipulating images in an image processing system where each image in the system is subdivided into a plurality of sub-images which are processed independently of one another. Control of each image and sub-image is maintained by means of a view state word or table so that only those portions of an image which are being actively processed require modification of their view state. The images stored in the system are maintained in a secondary store and only portions of the image are available for manipulation at any one time in a primary store. Manipulation of sub-images is determined by a modified Least Recently Used algorithm which minimizes data swaps between the primary and secondary stores.
