Abstract
When an image is to be rotated, the image is divided into blocks each having a predetermined size, and rotation of the image is realized by rotation of the respective blocks and rotation in units of blocks over the entire image. In this case, lines included in each block are moved to a predetermined region so that the lines are continuous in the order of lines. In the region in which the lines are moved as described above, predetermined digit positions in the respective lines appear at intervals of pixels for one line irrespective of the digit positions. After the respective digits are set to have a predetermined positional relationship between lines, since a logic operation is simultaneously performed for a plurality of lines, a plurality of pixels can be simultaneously moved to have a positional relationship after rotation. Also, a plurality of sets of pixels having the positional relationship after rotation can be similarly, simultaneously moved.
