<P>PROBLEM TO BE SOLVED: To provide an image processor and image processing method for eliminating such inconveniences that pixels are not projected to a converted image with a blank left due to a rounding error when performing conversion into an integer by affine transformation and performing image processing of high quality in a short period of time. <P>SOLUTION: When performing affine transformation of an original image, inverse affine transformation is performed on a pixel in a range where a transformed image is projected and it is projected to the original image; rounding is performed on coordinate value of projected coordinates and converting the value into an integer a value; a pixel value of the original image corresponding to the rounded coordinate value is obtained; and the pixel value is made to be a pixel value for the transformed image. <P>COPYRIGHT: (C)2008,JPO&INPIT |
