By analyzing an image of a cell sample, whether a cell shown in the image is cancerous or not, the type of cancer, etc. are objectively and appropriately determined. An image analyzing device () includes: a binarizing section () which carries out a binarizing process a plurality of times with respect to a single captured image so as to generate a plurality of binarized images, the binarizing section carrying out the binarizing process each time the binarizing section varies a binarization reference value; a Betti number calculating section () which calculates a region number, which indicates the number of hole-shaped regions, with respect to each of the plurality of binarized images which have been generated; and a cancer determining section () which determines a type of cancer occurring in a cell included in tissue, on the basis of the binarization reference value which has been applied at a time of generation of one of the plurality of binarized images with respect to which one the region number has a given value.
