摘要： An image analyzer including: an area setting unit configured to extract a scratch area that is an area having no cells from a reference image selected from a plurality of images acquired by imaging cells in a time series and set a reference region corresponding to the scratch area in the plurality of images; a calculation unit configured to calculate an area of a cell region within the reference region and/or the ratio of an area of the cell region to the reference region from the plurality of images; and a control unit configured to cause a display device to display a change in a time series of the calculated area of the cell region and/or the ratio of the area of the cell region to the reference region.

摘要： A cell tracking method is a cell tracking method for performing cell tracking on the basis of a plurality of cell images captured in time series, and includes an extraction process of extracting a tracking region corresponding to the cell for each of the plurality of cell images, a position calculation process of calculating a change in a position of the tracking region extracted in the extraction process on the basis of the plurality of cell images and tracking the cell on the basis of the calculated change in the position of the tracking region, a determination process of determining whether or not the cell as a tracking target is in a cell division state on the basis of the cell image, and a stop process of stopping the tracking of the cell when the cell is determined to be in the cell division state in the determination process.
