An image acquisition unit () acquires an analysis image. The analysis image is an image in which a plurality of cell nuclei in a lesion of a target person are captured. A feature-value calculation unit () calculates the feature-value relating to the cell nuclei from the analysis image. An evaluation function acquisition unit () acquires an evaluation function from an evaluation function storage unit (). The evaluation function is a function with which prediction information is calculated based on the feature-value. The prediction information generation unit () generates prediction information relating to a target person based on a feature-value, which has been calculated from an analysis image, and an evaluation function which has been acquired by the evaluation function acquisition unit (). The prediction information is information indicating a prediction of a prognosis of a disease of the target person or a prediction of malignancy of a disease of the target person.

Disease analysis apparatus, control method, and program
