摘要： A method for assessing an assessment target according to an embodiment includes: a step of acquiring statistical information based on at least one color feature quantity with respect to each of a plurality of assessment regions in a plate image corresponding to an image of an assessment plate that holds an assessment target in a plurality of wells provided in the plate; and a step of determining a color of the plurality of assessment regions by using the statistical information. The assessment target includes a tester, the plurality of wells include a test substance well holding the assessment target that further includes a test substance, the plate image includes a plurality of well images corresponding to the plurality of wells, and each of the plurality of assessment regions includes at least one well image corresponding to at least one of the wells.

摘要： A method for evaluating a plate including a plurality of wells, the method including: an injection step of injecting an evaluation sample including a cell and a test substance into the plurality of wells, the evaluation sample being adjusted in advance so that a foreign matter is generated as a result of cell death caused by the test substance; a counting step of counting the number of wells having the foreign matter among the plurality of wells at a first counting timing at which a first predetermined time has elapsed since the evaluation sample is injected into the plurality of wells; and a determination step of determining that the plate is appropriate when the number of wells having the foreign matter among the plurality of wells is one or more, and determining that the plate is inappropriate when the number of wells having the foreign matter is zero.
