1. An image analysis device comprising:
a processor;
a memory encoded with instructions executed by the processor, the instructions causing the processor to perform operations comprising:
executing a distribution information acquiring unit to acquire, based on an image in which a plurality of cultivated cells are imaged, distribution information relating to a distribution in a predetermined range of the plurality of cultivated cells, wherein the distribution information relates to i) a number of representative points of other cells present in the predetermined range of which a center is a representative point of a predetermined cell among the plurality of cultivated cells, and ii) a frequency at which cells having the number of representative points are detected; and
executing a determination unit to determine a cultivated state of the plurality of cultivated cells based on a number of the frequency indicated by the distribution information and the number of representative points of the other cells existing in the predetermined range.
