Abstract

Image display apparatus comprises a display monitor; an image frame buffer for storing data defining the color content of pixels of an image; and a control system for selecting from the frame buffer for each pixel displayed on the monitor the appropriate pixel data from the frame buffer. The relationship between the monitor pixels and the frame buffer pixels is defined by a preselected composite linear function, wherein the control system determines the frame buffer pixels corresponding to the monitor pixels by applying the preselected composite linear function in a stepwise manner.
