Abstract
Image data having a total number of pixels being H×V is written in SDRAM having an enough number of recording domains capable of storing all the pixel data of the image data and the number of Column addresses set therein at 2(4≦n) in the order of lines after the implementation of a first image rotation processing at a rotation angle of 90°×m (0≦m≦3) to the image data and read from the SDRAM in the order of the lines after the implementation of a second image rotation processing at a rotation angle of 90°×p (0≦p≦3). In doing so, the recording domains of the SDRAM are divided into a plurality of recording blockshaving the number of the Column addresses set therein at 2(2≦q≦(n−2) and capable of storing groups of the pixels for one line in the image data after the implementation of the first image rotation processing. The groups of the pixels for one line in the image data in an image direction after the implementation of the first image rotation processing are written in the recording blocks. The written image data is read from the SDRAM in an image direction after the implementation of the second image rotation processing.
