Patent ID: 7256797

Claim:
An image processing device comprising: a first reading device for making a read access to a memory that stores a plurality of compressed image data, each of which is comprised of a plurality of blocks each having a predetermined size in advance, so as to read the compressed image data block-by-block; a decoder for decoding the compressed image data block-by-block so as to produce decompressed image data; a first storage device serving as a first-in-first-out memory, which is given a priority in a write operation for writing the decompressed image data therein rather than a read operation for reading the decompressed image data therefrom, and is incapable of simultaneously performing the write operation and the read operation and has a storage area operable for storing a plurality of decompressed image data decoded by the decoder; a writing device for writing the decompressed image data into the first storage device block-by-block; a second reading device for reading the decompressed image data from the first storage device; a second storage device that is given a priority in a read operation for reading therefrom rather than a write operation for writing therein and is incapable of simultaneously performing the read operation and the write operation; a control device for performing prescribed processing on the image data read from the first storage device and for writing the processed image data into the second storage device; and a display device for reading the processed image data from the second storage device and for displaying an image based on the processed image data.
