Abstract
An image generation method for generating image information of an image C by using an image A and an image B having a bit depth higher than that of image A. Image C having the same bit depth as image B is generated by increasing the bit depth of image A by means of tone mapping; presence or absence of a point in image B corresponding to each pixel position of image C and the position of the relevant corresponding point are estimated; and to each pixel position in image C for which it is estimated that there is a corresponding point, image information of the corresponding position in image B is assigned. It is possible to generate image information at each pixel position in image C for which it is estimated in the corresponding point estimation that there is no corresponding point, by using the image information assigned according to an estimation result that there is a corresponding point.
