2. Related Art
There is a need for rotating image data exactly by a given angle when handling image data obtained by digitizing an image.
For example, in the case of rotating image data that has been encoded using a JPEG (joint photographic experts group) scheme, a method of performing rotation after decoding the whole image data is conceivable. For this method, refer to paragraph 0009 of Japanese Patent No. 3661520.
Disadvantageously, this method requires a large capacity buffer to temporarily store the whole image data that has been decoded for rotation processing.
