This invention solves the problem of displaying two images simultaneously in the same screen space, with rapid alteration of the transparency of the foreground image with respect to the background image, without using multiple image planes. This invention creates a single, 8 bit-per-pixel composite image from the foreground and background images. A color look-up table is also created. The color look-up table is a stored data array which indicates the value of each color which can be simultaneously displayed on the screen. By manipulating the color look-up table, the foreground image can be faded in and out rapidly.
