Patent ID: 8594435

Claim:
An image processing device that specifies a region including a specific subject on each input image of a plurality of continuous frames, the image processing device comprising: subject map generation means that, from feature maps corresponding to features of respective pixels of the input image and representing feature amounts in respective regions of the input image, selects one feature amount of any of the feature maps for each pixel so as to thereby generate a subject map representing similarities of the respective regions of the input image to the subject; subject region specification means that, on the basis of the subject map, specifies a subject region, which is a region most similar to the subject, in the subject map so as to thereby specify a region which includes the subject on the input image; and reliability calculation means that calculates reliabilities as indicators indicating that corresponding regions, which correspond to the subject region of a frame previous to a processing target frame, on the feature maps includes the subject, on the basis of degrees of distribution of the feature amounts in near-field regions which include the corresponding regions on the feature maps of the processing target frame, wherein the subject map generation means generates the subject map by selecting one feature amount of any of the feature maps for each pixel on the basis of the reliabilities of the respective feature maps.
