PROBLEM TO BE SOLVED: To provide an image deformation device that can accurately deal with complicated deformation while reducing a capacity of a memory memorizing a position correction amount for each pixel that a correction part refers to.SOLUTION: An image deformation device comprises: a primary memory 11 which memorizes one page or a plurality pages of position correction amount data for every pixel position, which is used for correction of pixel positions; a reference memory 15 whose memory region is smaller than the memory region of the primary memory 11; a transfer control part 13 that separately transfers, multiple times, the position correction data from the primary memory 11 to the reference memory 15; and a position correcting part 16 that executes a position correcting process for sequentially correcting, based on the position correction data in the reference memory 15, a pixel position of each pixel of an input image in predetermined order. The transfer control part 13 sequentially transfers the position correction data from the primary memory 11 to the reference memory 15 in accordance with the order of processes and progress in the position correction part 16.SELECTED DRAWING: Figure 1 |
