Abstract
An operation for correcting horizontally an array of pixels in two-dimensional image data is performed so that a plurality of divided frames are joined properly in position in the horizontal direction and displayed. The horizontally corrected image data is stored, in the order of write address, on memories for storing image data. The image data stored is read in the same order as the order of write address or in the order different from the order of write address. The image data outputted from the memories for storing image data is vertically corrected so that the divided frames are joined properly in position in the vertical direction and displayed.
