Claim Text:
1. A cell analysis method in a cell analysis device that uses a quantitative optical path length image of a cell colony formed of a number of cells to analyze the cell colony, the method comprising: acquiring the quantitative optical path length image of the cell colony by an acquisition unit of the cell analysis device; extracting a circular shape corresponding to a cell nucleus of a cell in the acquired quantitative optical path length image by an extraction unit of the cell analysis device; comparing an inner optical path length in an inner region of the extracted circular shape and an outer optical path length in an outer region of the extracted circular shape by a comparison unit of the cell analysis device; and analyzing the cell colony based on the comparison result by an analysis unit of the cell analysis device to identify a cell with good quality, wherein the outer optical path length of the circular shape is larger than the inner optical path length of the circular shape for the cell with good quality.
