IMAGE GENERATION METHOD, DEVICE, ITS PROGRAM AND RECORDING MEDIUM STORED WITH PROGRAM

摘要

An image generation method, which generates image information of an image (C) from an image (A) and an image (B) that is higher in bit depth than the image (A), carries out the tone mapping of the image (A) to generate the image (C) that has the same bit depth as the image (B); estimates each pixel position of the image (C), the existence or absence of its corresponding point in the image (B) and a position of its corresponding point; and sets image information of the corresponding position in the image (B) at the pixel position in the image (C) where the existence of the corresponding point is estimated. Image information at the pixel position in the image (C) where the absence of the corresponding point is estimated by the corresponding point estimation may be made out from such image information that the existence of the corresponding point is estimated and is set.
