PURPOSE:To attain an affine transformation without limiting to the size of a picture to be able to execute the affine transformation and at a high speed by dividing the affine transformation of an original picture with respective processors and preparing the converted picture. CONSTITUTION:Plural processors 1 to execute the affine transformation are provided, and respective processors 1 executes the affine transformation concerning respective blocks divided into the block of the figure specified based on the size of an original picture 2 or a converted picture 3 and the size of an input buffer 5 and an output buffer 6 of processors 1. When the converted picture obtained by plural processors 1 is synthesized, the complete converted picture 3 of the original picture 2 is obtained. Thus, when the original picture is affine-converted, by dividing into a suitable size and executing the affine transformation in parallel with plural processors, the high speed processing can be performed and there is no limit to the size of the picture to be able to execute the affine transformation. |
