1. An information processing device, comprising circuitry configured to:
generate difference information related to a difference between a first image and a second image, the difference information having a plurality of areas;
obtain, in a sequential order with respect to the plurality of areas of the difference information, a total value of differences in each of the plurality of areas as one of a plurality of total area difference amounts;
determine whether the first image is the same as the second image, as perceptible by a human eye, based on each of the plurality of total area difference amounts;
divide the plurality of total difference amounts by a threshold value to obtain a difference value for a corresponding one of the plurality of areas;
set, based on the difference value, an intensity of color of the corresponding one of the plurality of areas; and
generate a difference image based on each of the plurality of total area difference amounts in response to determining that the first image is not the same as the second image.
