Abstract

The present invention reduces the difference between methods for capturing images to be used for machine-learning.　The information processing device generates a histogram that indicates the number of pixels for each brightness value of a first image of a first subject captured in a first image-capturing condition. In addition, the information processing device generates a histogram that indicates the number of pixels for each brightness value of a second image of a second subject of the same type as the first subject captured in a second image-capturing condition. Then, the information processing device generates a conversion rule, by which the similarity of the histogram of the first image and the histogram of the second image is improved, for the pixel brightness values of the second image. Then, the information processing device converts, according to the conversion rule, the brightness value of each pixel of a third image of a third subject of the same type as the first subject captured in the second image-capturing condition. In addition, the information processing device executes machine-learning using the third image of which the brightness values are converted.
