Abstract
Image display apparatus comprises, a monitor (6); a monitor control system (4,5) connected to the monitor (6); and a color modifying circuit (2) for receiving from a store (1) first signals representing the color content of pixels of an image and for generating monitor control signals for each pixel which are fed to the monitor control system. The color modifying circuit (2) generates for any first signals representing a color which falls outside the gamut of colors normally displayable by the monitor (6), monitor control signals representing a respective equivalent color which falls within the monitor gamut, by applying a predetermined algorithm to the first signals which desaturates all the image colors while leaving hue and intensity unaffected.
