PROBLEM TO BE SOLVED: To provide a memory control unit capable of properly executing overtaking control even when performing data division processing. SOLUTION: Storing image data of a write area 301 in a DRAM 106, a memory control circuit 105 divides and reads the image data in a read area 302 from the DRAM 106. At this time, read processing is controlled not to take place earlier than write processing. To ensure a distance (spacing) between write processing and read processing to be the nearest, the number of addresses corresponding to the length W_Hsize of image data for one line is set in a register 207.
