Claim 9:
10. A cell state evaluation device comprising:
a processor;
a memory encoded with instructions executed by the processor, the instructions causing the processor to perform operations comprising:
calculating color information of a least one or a combination of hue, saturation, or lightness in the color space of an image of one captured cell or a plurality of captured cells in a captured image;
determining the cultured state of the cell or cells on the basis of the color information and color reference information;
storing a reference value for determining positive type, which is set on the basis of the color information of the image of one sample cell or a plurality of sample cells in the color space as the color reference information which is the determination standard;
obtaining a center of gravity of the color information or a statistic of the color information on the bases of the color information of the plurality of cells; and
calculating a distance between the center of gravity or the statistic of the color information and the reference value,
wherein the determining includes determining the culture state of the one or a plurality of captured cells on the basis of the increase or decrease in the distance.
