IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image processing apparatus configured to easily estimate a camera parameter.SOLUTION: An image processing apparatus configured to estimate a camera parameter of a camera which has captured refocus-able images from the two refocus-able images having an overlapping area and variable focal depth includes: input means which inputs the two refocus-able images, a refocused-image division number which is the number of divisions of an image having a predetermined focal depth, and an internal parameter of the camera; image processing means which detects features points of refocused images and a feature-point corresponding group between the refocused images from the two refocus-able images, and outputs them; and geometric processing means which estimates a camera parameter from the feature-point corresponding group and the positions of the feature points.
