Abstract
An image processing system is arranged to convert data representing a picture element with an original color defined in terms of original brightness and hue values into data representing the picture element with a new color, different than the original color. In the system a new hue value is calculated from the original hue value by way of a transforming circuit . The original and new hue values are both processed in look up tables to determine respective inherent brightness values associated therewith. The original brightness value is processed with the inherent brightness values by way of a subtracter and an adder to produce a new brightness value that together with the new hue value defines the new color of the pixel.
