Claim One:
1. An image processing apparatus comprising: a captured image obtaining unit configured to obtain a captured image of a subject on a stage, the captured image being captured by an image capturing device; a distance image obtaining unit configured to obtain a distance image of the subject, the distance image being generated by a distance image generating device; a candidate point detecting unit configured to set a plurality of division lines at predetermined intervals on an area including the subject in the distance image obtained by the distance image obtaining unit, and, on the basis of distance information on the division line, to detect, for each of the division lines, a point at which a change amount of a distance is larger than a threshold on the division line, as a candidate point of a contour of the subject; a line detecting unit configured to detect a line in the captured image on the basis of luminance information of the captured image obtained by the captured image obtaining unit; and a determining unit configured to determine, in the captured image, one line in the plurality of lines as the contour of the subject, on the basis of a positional relation between the plurality of lines detected by the line detecting unit and the plurality of candidate points detected by the candidate point detecting unit.
