PROBLEM TO BE SOLVED: To apply replacement processing of an image drawing instruction to realize high- speed image processing to a wider range. SOLUTION: The image processing unit is provided with an image drawing instruction conversion section 1 that receives an image drawing instruction to convert it into image drawing information, a logic arithmetic instruction discrimination section 2 that discriminates whether a logic arithmetic instruction of the converted image drawing information is in matching with a process possible instruction pattern without logic arithmetic processing, an image drawing information storage section 3 that sequentially stores the image drawing information discriminated to be in matching with the process possible instruction pattern without the logic arithmetic processing, an interruption image drawing information processing section 4 that compares the image drawing area information of the stored image drawing information with the image drawing area information of the converted image drawing information afterward and individually processes the converted image drawing information afterward when both the image drawing areas are not overlapped, and an image drawing instruction replacement section 5 that replaces the image drawing information of a specified number with the image drawing instruction not needing the logical arithmetic operation when the image drawing information storage section 3 stores a specified number of the image drawing information items in matching with the process possible instruction pattern without the logic arithmetic processing. |
