The image orders coordinate the position and size of a source rectangle area and the postion of a destination rectangle area in an image storage memory. The image data of the souce rectangle area is rotated by a rotation angle of 90 degrees, 180 degrees or 270 degrees and is stored in the image storage memory. The image storage memory operates as a storage buffer of a display unit, which displays the image data of the destination rectangle area. The image storage memory is partitioned into areas of K bits. Image data is rotated in blocks of K.times.K bits.
