PROBLEM TO BE SOLVED: To put a RAM for overdrive processing and a RAM for double-speed driving processing together into one RAM. SOLUTION: Input data is written as current frame data to a RAM 203, the input data written to the RAM 203 is read out as previous frame data, and the current frame data and previous frame data are added together by a correcting circuit 304 to be subjected to overdrive processing. Correction data 318 having been subjected to the overdriving processing is written as current frame correction data to the RAM 203, and the correction data written to the RAM 203 is read out as previous frame correction data to be subjected to double-speed driving processing.
