Abstract
Abstract An image processing apparatus includes a CPU which executes a program read from an external storage unit, and a video processor. In the video processor, color data of moving picture characters and color data of still picture characters are respectively outputted from a moving picture data generating circuit and a still picture data generating circuit. Both the color data are applied to a main/subsidiary data selection circuit which outputs the color data as main image data and subsidiary image data. An arithmetic circuit executes an arithmetic operation to obtain a mean value of both the color data. A video signal producing circuit converts the mean value of the color data from the arithmetic circuit into a video signal which is then applied to a display.
