Title: IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM
Abstract:
In order to produce a natural image having a three-dimensional effect by correcting a high-intensity region of the image, this image processing device is equipped with: a first acquisition means for acquiring normal-line information corresponding to an image; an estimation means for estimating an actual illumination parameter on the basis of a high-intensity region of a photographic subject included in the image; a first setting means for setting a virtual illumination parameter on the basis of the actual illumination parameter; and a lightening processing means for executing a lightening process with respect to the image on the basis of the normal-line information and the virtual illumination parameter.
