To increase calculation accuracy of probability that an image in a display subject region in a captured image obtained by image-capturing a sample piece including a target cell having a nucleus is an image of the target cell. A nucleus-candidate-region extracting unit (10) extracts, from a captured image obtained by image-capturing a sample piece including a target cell having a nucleus, a nucleus candidate region corresponding to the nucleus. A reliability calculating unit (16) acquires, for each of a plurality of determination subject regions determined on the basis of the nucleus candidate region, reliability indicating probability that an image in the determination subject region is an image of the target cell, on the basis of a feature amount of the image of the determination subject region. A display-subject-region setting unit (20) calculates integrated reliability indicating probability that an image in a display subject region corresponding to the nucleus candidate region is the image of the target cell on the basis of the reliability acquired for each determination subject region determined on the basis of the nucleus candidate region. |
