IMAGE PROCESSING DEVICE, IMAGE CAPTURE DEVICE, AND IMAGE PROCESSING PROGRAM

摘要

The disclosed image processing device is provided with an acquisition unit for acquiring information of an object image to be an object of processing; a region partitioning unit for partitioning the object image into a plurality of blocks; a setting unit for setting one or more templates on the basis of images of one or more blocks existing on an outer peripheral portion of the object image among the plurality of blocks; a calculation unit for calculating a representative value for each of the plurality of blocks into which the object image has been partitioned; a matching unit for performing matching for each of the plurality of blocks by comparing a representative value of a block to be matched with representative values in the one or more templates; and a creation unit for creating maps indicating distribution of a subject in the object image on the basis of the results of the matching by the matching unit; whereby extraction of a main subject region is performed by a method compatible with the object image without depending on high frequency components or assuming an empirical composition.
