Abstract: A video display apparatus includes a video data generator which generates video data of a plurality of still picture and a moving picture (graphic data) in an overlaid manner on the basis of still picture patterns, still picture character codes, moving picture character codes and etc. programmed in an external storage unit in advance. A microprocessor applies, in accordance with priority data for the still pictures and the moving picture and mode data both programmed in the external storage unit in advance, first priority data to the video data of the still picture characters and second priority data to the video data of the moving picture character, respectively. A priority encoder selects a still picture character or a moving picture character having the highest priority on the basis of the first and second priority data, and applies the number of that character to a decoder. The decoder outputs a gate control signal in accordance with the number.

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.
