  • Patent number: 9916658
    Abstract: An image acquisition unit (2020) 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 (2040) calculates the feature-value relating to the cell nuclei from the analysis image. An evaluation function acquisition unit (2060) acquires an evaluation function from an evaluation function storage unit (10). The evaluation function is a function with which prediction information is calculated based on the feature-value. The prediction information generation unit (2080) 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 (2060). 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.

  • Patent number: 8068133
    Abstract: An image processing apparatus includes a first spectrum estimating unit for reading the image information from a storage unit and estimating a spectrum of an object based on the read image information; a dye amount estimating unit for estimating dye amounts included in the object using the estimated spectrum; a second spectrum estimating unit for synthesizing a first spectrum using the estimated dye amounts; a spectrum subtractor for calculating a difference spectrum by subtracting the first spectrum from the spectrum; a dye amount correcting unit for correcting at least a part of the estimated dye amounts; a third spectrum estimating unit for synthesizing a second spectrum using the corrected dye amount; a spectrum adder for synthesizing a third spectrum by adding the second spectrum and the difference spectrum; and an image synthesizer for synthesizing a display image from the third spectrum.
