PURPOSE: To increase the processing speed, to improve the memory efficiency, and to plot a picture of high quality by copying bits on the original picture obtained by inverse affine transformation to all bits of a deformed picture to generate the picture data of the deformed picture. CONSTITUTION: The principal part consists of a central processing unit 1 which controls the operation of the whole of a system, a storage device 2 provided with a ROM where a control program or the like is stored, a buffer for storage of bit information, etc., an input device 3 for input of various input information, and a graphic display device 4 provided with a bit map memory. Inverse affine transformation as inverse transformation to affine transformation is obtained, and all of bits constituting the deformed picture are subjected to inverse affine transformation to obtain the bits on the original picture, and obtained bits on the original picture are copied to all bits of the deformed picture. |
