1. An information processing device, comprising:
a central processing unit (CPU) configured to:
estimate, based on a first image and a second image, a deterioration of the first image due to a substance generated during a surgery, wherein
the first image is an image regarding the surgery, and
the second image is an image prior to the first image;
generate a converted image in which a pixel value of the first image is converted so that a histogram of the first image matches a histogram of the second image;
calculate a correction amount map based on the converted image and the first image; and
generate an output image based on the correction amount map and a correction of the first image, wherein
the correction of the first image is based on the deterioration of the first image.
