Abstract
A removal region detection means detects a rectangular non-update region from a circumscribed rectangle of all update blocks. An update region dividing means divides the circumscribed rectangle of all update blocks into two or more rectangular update regions not including the detected non-update region. If the number of update regions after the division does not exceeds a threshold, a division processing control means recursively applies the processing by the removal region detection means on the update regions after the division, and recursively applies the processing by the update region dividing means based on the detected non-update region. The division processing control means terminates repetition of the division processing of the update region on a condition that a new non-update region is not detected any more by the removal region detection means, or that the number of update regions exceeds the threshold, whichever is satisfied earlier.
