Patent ID: 7720293

Claim:
An image processing apparatus comprising: an internal memory, adapted to store a compressed image data of a compressed image therein; a processor, operable to acquire the compressed image data image data corresponding to at least a column of the compressed image from an external memory and to store the compressed image data in the internal memory; and an image processing circuit, having: a generating section, operable to analyze the compressed image data stored in the external memory and generate an analytic table indicative of a storage manner of the compressed image data; a decoding section, operable to read and decode the compressed image data stored in the internal memory by the processor, and rotate and output a decoding image data as a rotated image; and an updater, operable to update the analytic table in accordance with a decoding situation of the decoding section, wherein the processor is operable to store the image data in the internal memory with reference to the analytic table.
