IMAGE GENERATION METHOD AND APPARATUS, PROGRAM THEREFOR, AND STORAGE MEDIUM WHICH STORES THE PROGRAM

An image generation method for generating image information of a color signal Y of an image A by using a color signal X of image A, and color signal X and color signal Y of an image B. The presence or absence of a point in color signal X of image B corresponding to each pixel position of color signal X of image A, and the position of the relevant corresponding point are estimated. To each estimated pixel position in color signal Y of image A, image information of the corresponding position in the second color signal Y of image B is assigned. Color signal Y at a pixel position in image A for which it is estimated that there is no corresponding point is generated by using the image information of color signal Y assigned to pixels having a corresponding point.
