PROBLEM TO BE SOLVED: To plot a picture in the middle of deforming in real time by setting the pixel value of the pixel coordinates of an original picture o the pixel coordinates of a deformed picture corresponding to the pixel coordinates of a specified original picture and the interpolated pixel coordinates of the specified deformed picture so as to improve the efficiency of processing in the case of executing nonsimilar deformation. SOLUTION: This picture deforming device 10 is provided with a means for specifying the picture coordinates of a deformed picture corresponding to the pixel coordinates of an original picture, a means for specifying the interpolated pixel coordinates of the deformed picture based on deforming information showing the deforming method of the original picture, and a means for setting the pixel value of the pixel coordinates of the original picture to the specified pixel coordinates and the interpolated pixel coordinates. In this device 10, a pixel value setting part 17 sets a pixel value to the pixel coordinates generated by a deformed picture coordinate generating part 15 and the interpolated pixel coordinates generated by an interpolated coordinate generating part 16 to generate a deformed picture 4. A deformed picture output part 18 fetches this picture 4, and converts it into a prescribed format to output it to a display part 19, which displays the outputted picture 4 on its screen. |
