PURPOSE:To provide the image data processor capable of easily performing various image processes as to an image data processor which processes normal input image data and performs image processing for the top-bottom and right- left inversion, enlargement, reduction, etc., of a screen based upon the input image data. CONSTITUTION:An address generation part 16 which determines the write addresses and read addresses of data to a memory part 12 consists of a write address generation part 17, a read address generation part 18, a write/read switching part 19, and an address control part 20; and the write address generation part 17 generates increasing and decreasing addresses by up counters 23 and 25 and down counters 24 and 25 and the address control part 20 selects the increasing or decreasing addresses. Then the write address order of data is controlled to control the write addresses of the data, thereby inverting and rotating the image. |
