Claim 11:
12. The image processing device according to claim 7, wherein
the operation of extracting the colony region is an operation in which a colony mask is generated based on the extracted colony region and a normal region mask is generated based on a normal region obtained by excluding an abnormal region from the colony region,
the operation of extracting the focused region is an operation in which (i) a focused region with pixels with relatively high luminance in the image is extracted, (ii) a focused region mask that includes a high density region and a striated region in regions surrounding nuclei of the pluripotent stem cells is generated based on an image of the focused region, and (iii) a dense/striated mask is generated based on the normal region mask and the focused region mask, and
the operation of extracting the extraction target region is an operation in which the striated region is extracted based on the image and the dense/striated mask acquired.
