ABSTRACT:
An image output system and method which outputs high-resolution, high-quality images, while using a limited amount of frame memory. A CPU 1 reads and executes a program stored in a ROM 2, and writes image data, read from the ROM 2 or obtained by calculating data contained in the ROM 2, into a frame memory 6. The image data stored in the frame memory consists of length values and color data for the pixels to be displayed on an output screen. By storing image data according to length values and color data, the amount of data to be stored in the frame memory is reduced. The image data stored in the frame memory 6 is converted to the image display signal for each pixel, based upon length values and color data. The image display signal is then sent to the image display system 14 via the video signal generation means 13. An image that is displayed on an image output system can be changed by merely changing a length value in the image data read from the frame memory, without having to change the contents of image data stored in the frame memory, which reduces the amount of required hardware.
