Claim Text:
1. An image processing apparatus comprising: a photographed data input unit configured to acquire a plurality of images photographed from at least two different viewing positions; an input unit configured to input a refocus parameter representing a distance from a camera to a virtual focal plane; a distance estimation unit configured to generate a depth map for the acquired images indicating distances between photographed objects corresponding to pixels and a camera; a focus map generation unit configured to generate a focus map indicating an in-focus area to be sharply focused and an out-of-focus area to be blurred, by calculating areas including the in-focus area and the out-of-focus area from the depth map according to the refocus parameters; an in-focus area image processing unit configured to generate a synthesized image by performing a resolution enhancement process on the in-focus area and synthesizing a group of images including at least the photographed images; an out-of-focus area image processing unit configured to generate a synthesized image by performing an operation, different from the resolution enhancement process performed by the in-focus area image processing unit, on the out-of-focus area and synthesizing a group of images including at least the photographed images, wherein the out-of-focus area image processing unit further comprises: an image blending unit configured to generate a refocused image by blending the synthesized image of the in-focus area and the synthesized image of the out-of-focus area according to the focus map.
