<p><P>PROBLEM TO BE SOLVED: To reduce processing time by reducing both memories of an input/output images, for solving the problem wherein setting a minimum necessary line range of an output image becomes difficult, because prior art distortion correction processing requires a large capacity of memory, since processing is performed after all input images have been read, and pixels of the input images have been moved after distortion correction, and its moving amount is not fixed and differs from pixel to pixel. <P>SOLUTION: An image distortion correction processing method has a correction processing means for performing correction processing per pixel of an output image 106, by using data of a pixel of an input image 101, and acquires only the number of lines of input images required for obtaining one line of an output image, by reading the pixels of the input image so that data of pixels subjected to correction processing are outputted by line, in the order of scanning of the output image. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
