摘要：
An ocular fundus image processing device 1 includes an image input unit 3 configured to acquire a first image generated by irradiating an ocular fundus of a subject with excitation light of a blue wavelength and a second image generated by irradiating the ocular fundus with excitation light of a green wavelength, a model generating unit 7 configured to generate three trained models for predicting a correction factor for calculating a quantity of macular pigment of the subject from input images including the first image and the second image through training using three different initial values, a coefficient predicting unit 9 configured to predict three correction factors by inputting the input images including the first image and the second image to the three trained models, a coefficient deriving unit 11 configured to calculate a statistical value of the three correction factors and to derive the statistical value as the correction factor of the subject, and a pigment quantity calculating unit 13 configured to calculate a quantity of macular pigment of the subject on the basis of the first image and the correction factor of the subject.
