Claim 11:
12. A non-transitory computer-readable medium having stored thereon instructions configured to cause one or more computers to perform steps comprising:
inputting first image data, second image data, non-cancer image data, and third image data, wherein
the first image data represents an image of a pathological section of stained hypermutated cancer,
the second image data represents an image of a pathological section of cancer which is not hypermutated, and is stained same as the pathological section of the first image data,
the non-cancer image data represents an image which is not a pathological section of cancer, and
the third image data represents an image of a pathological section which is newly determined whether cancer or not and whether hypermutated or not, and is stained same as the pathological section of the first image data;

holding the first image data, the second image data, and the non-cancer image data;
performing a Z value conversion process for the first image data, the second image data, the non-cancer image data, and the third image data, converting each RGB color in each pixel into Z value in the CIE color system based on the entire color distribution of the first image data, the second image data, the non-cancer image data, and the third image data;
generating a first determination model determining whether an image represents a pathological section of cancer or not, using the first image data, the second image data, and the non-cancer image data converted by the Z value conversion process and held as training data;
generating a second determination model determining whether a cancer is hypermutated or not, using the first image data and the second image data converted by the Z value conversion process and held as training data;
determining whether the third image data represents an image of cancer or not by inputting the third image data converted by the Z value conversion process into the first determination model; and
determining whether the third image data represents an image of hypermutated cancer or not by inputting the third image data converted by the Z value conversion process into the second determination model.
