IMAGE PROCESSING DEVICE, METHOD, AND PROGRAM

WIPO Patent Application WO/2010/131593

A1

Disclosed are an image processing device, method, and program, which enable the area of a subject on an image to be more accurately identified. A subject map generating unit (21) generates a subject map indicating the area-likeness of a subject in each of the areas of an input image from the input image. A gradient map generating unit (22) generates a gradient map indicating the degree of change in the subject-likeness in the subject map. A threshold processing unit (23) and a threshold processing unit (24) binarize the gradient map using a high threshold (THh) and a low threshold (THl) to obtain threshold maps. A composite map generating unit (25) generates a composite map indicating the subject-likeness in each of the areas of the input image on the assumption that an area which includes the areas identified as being the subject-likeness, by means of a threshold map with the high threshold (THh) out of the areas identified as being the subject-likeness by means of a threshold map with the low threshold (THl) is the area of the subject. The present invention is applicable to an image processing device.
