Abstract:
1. An image processing method comprising: a first step of obtaining a plurality of input images obtained by shooting a same object; a second step of dividing each of the obtained input images into a plurality of small regions; a third step of generating a base image of each of the divided small regions using the input images; and a fourth step of generating a base image of a small region having been impossible to generate a base image by interpolation processing using a computed value for base image generation in neighbor small regions, the small region and the neighbor small regions being of the divided small regions, wherein a linearized image of the object under given lighting condition is generated using the generated base images; wherein the third step includes the steps of: selecting N base original images from K input images (N is a positive integer smaller than K); determining a linearization coefficient set for each remaining (K−N) input image using the N base original images; and generating N base images by linearizing the N base original images using the determined linearization coefficient set.
