Patent Images
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.

Abstract
An image region dividing section (105) partitions each of input images into a small regions, and a small region synthesized image generation section (106) generates a base image of each small region, which is an image including only diffuse reflection, from each input image. An image interpolation section (107) generates by interpolation a base image of a small region of which base image cannot be generated. A linearized image generation section (103) generates a linearized image, which is an image in an ideal state under given lighting condition, using the base image of each small region.
