Abstract
A threshold determination method includes a region specification step of specifying cell regions corresponding to individual cells in an image obtained by imaging the biological specimen, a determination step of setting temporarily a threshold for staining density quantitatively indicating the degree of staining of the cell region, comparing the staining density and the threshold for each of the cell regions and determining whether a stained state is positive or negative for staining, a receiving step of displaying a determination result of the stained state of each of the cell regions and receiving an operation input of a user to change the determination result for each cell region, and a resetting step of resetting the threshold in accordance with the determination result after change. It is possible to optimize effectively a threshold used in determining a stained state from an image of an immunohistostained specimen while human judgment is made.
