Abstract

A method of displaying a selected section of an N-dimensional color space uses two memories (14,16). The first memory (14) stores memory addresses of the second (16). The second memory (16) stores data defining color at addresses corresponding to the selected section and background color at all other addresses. The defined colors and background are output to a display (11) so that the background areas blend with the existing background and only the color of the selected section is redrawn not the whole image.
