Claim One:
1. An image processing apparatus comprising: a line-candidate identifying unit that identifies a plurality of candidates of lines that constitute a contour of a subject region, on the basis of a captured image including an image of a subject captured with an imaging apparatus, the subject region corresponding to the image of the subject; a line-probability calculating unit that calculates, for each of the plurality of candidates identified by the line-candidate identifying unit, line probability information representing a probability that the candidate is a line that constitutes the contour of the subject region, on the basis of feature values that are determined on the basis of the captured image and that are of positions located at or within a reference distance from the candidate; a region-probability calculating unit that calculates region probability information representing a probability that a target region surrounded by a predetermined number of candidates chosen from the plurality of candidates identified by the line-candidate identifying unit is the subject region, on the basis of the pieces of line probability information of the predetermined number of candidates; and a subject-region detecting unit that detects the subject region on the basis of the region probability information calculated by the region-probability calculating unit.
