Abstract: A cell evaluation method includes acquiring a first evaluation index and a first index calculated using the first evaluation index with respect to comparative target cells in a culture process including a cell differentiation-inducing process in which cell differentiation is induced, calculating a second index on the basis of the first evaluation index with respect to evaluation target cells different from the comparative target cells, and evaluating differentiation of the evaluation target cells by comparing the first index with the second index.

Abstract: An information processing device includes: an acquirer that acquires observation results obtained from a time-lapse image of a target object; and a controller that indicates, in a display image, analysis results visually representing the observation results and an increase/decrease time indicating an amount of time required to increase or decrease a predetermined value related to the target object. When a setting for a section in the analysis results has been received, the controller indicates, in the display image, the increase/decrease time corresponding to the section that has been set.
