Abstract: Provided are a cell life-and-death determination method, a cell life-and-death determination device, and a cell life-and-death determination system. The cell life-and-death determination method includes: acquiring images of a cell captured in a plurality of focal planes including an in-focus plane of the cell in a direction opposite to a side on which the cell is irradiated with light; acquiring an image piece including a central portion and an outer peripheral portion of the cell from each of the images; connecting the image pieces in an order of an imaging direction of the focal plane to create a connected image for analysis; extracting a feature amount from the connected image for analysis; and determining whether the cell is alive or dead on the basis of the feature amount of the connected image for analysis and a predetermined range of the feature amount.
