Image deformation device

An image deformation device for deforming an input image by correcting a position of each pixel in the input image, comprising:

• a primary memory in which a positional correction amount data for each pixel, which is used for correcting the position of each pixel, is stored;
• a secondary memory having a small storing area than the primary memory;
• a reference memory having a small storing area than the secondary memory;
• a first transfer unit configured to carry out a first transfer in which the positional correction amount data stored in the primary memory is transferred to the secondary memory separately in multiple times;
• a second transfer unit configured to carry out a second transfer in which the positional correction amount data stored in the secondary memory is transferred to the reference memory separately in multiple times;
• and
• a positional correction unit configured to carry out a positional correction process in which the position of each pixel in the input image is sequentially corrected in a predetermined order in accordance with the positional correction amount data stored in the reference memory,
• wherein the second transfer unit carries out the second transfer according to the predetermined order and a progress of the positional correction process in the positional correction unit so that the positional correction amount data for one pixel has been already stored in the reference memory when the positional correction unit corrects the position of the one pixel, and
• the first transfer unit carries out the first transfer according to the predetermined order and the progress of the positional correction process in the positional correction unit so that the positional correction amount data for the one pixel has been already stored in the secondary memory when the second transfer unit transfers the positional correction amount data for the one pixel to the reference memory.
