An objective of the present invention is to reduce, beyond a circumstance wherein this configuration is not present, the possibility of erroneous detection when searching for target cells by image processing from a captured image wherein target cells having nuclei are image captured. A captured image acquisition unit (22) acquires a captured image wherein a specimen including target cells having nuclei are image captured. A pixel extraction unit (24) extracts from pixels which are included in the captured image a pixel which is a nucleus candidate. A connected pixel group extraction unit (26) extracts a connected pixel group which is configured from pixels of a predetermined number of pixels or greater wherein mutually adjacent pixels are connected. On the basis of an image feature value which is identified on the basis of a brightness distribution for each of a plurality of mutually different color components within a region which encompasses at least a portion of the connected pixel group, and a condition of an image feature value which is mechanically learned on the basis of a brightness distribution for each of a plurality of mutually different color components within a sample image of the target cells, a possibility identification unit (40) identifies a value which denotes a possibility that the target cells are included in the regions. |
