Image display apparatus

摘要

Image de/coding unit 801 decodes coded image data and stores the image data on a temporary basis. Image address bus 123 and image data bus 124 connect image de/coding unit 801 and image display section 901. Image display section 901 stores image data like moving images in frame memory 914 which is a preexisting circuit, and displays the images that are for specified areas and that are produced in image de/coding unit 801 and previously produced images stored in frame memory 914 in overlap. By this means, it is possible to reduce the traffic on MPU (Micro Processor Unit) busses and to present large-volume image data such as moving images by relatively simple additions of functions.
