PROBLEM TO BE SOLVED: To search for a target cell by image processing from an image obtained by imaging the target cell having a nucleus, while reducing false detection as compared with other configurations.SOLUTION: A captured image acquisition part 22 acquires an image obtained by imaging a sample including a target cell having a nucleus. A pixel extraction section 24 extracts a pixel as a nucleus candidate from among pixels included in the captured image. A connected pixel group extraction section 26 extracts a connected pixel group formed by connecting adjacent pixels and including a predetermined number of pixels or more. A possibility specification section 40 specifies a value indicating possibility that the target cell is included in an area surrounding at least a part of the connected pixel group, on the basis of image feature quantity specified based on luminance distributions for different color components in the area and a condition of the image feature quantity machine-learned based on the luminance distributions for different color components in positive- and negative-example sample images of the target cell. |
