摘要： A passage timing calculation device includes a time change calculating section configured to calculate a time change in an area occupied by an extraction target region that is a region in which a striated pattern appears from a plurality of microscope images of pluripotent stem cells captured at different times, a change point detecting section configured to detect a change point of the time change in an area occupied by the extraction target region, and a passage timing calculating section configured to determine a passage timing of the pluripotent stem cells on the basis of the change point.
