1. An information processing apparatus, comprising: an acquisition section configured to acquire information of a lightness distribution of a first image captured by an image sensor, wherein the first image is obtained by a microscopy device, wherein the first image is an image of no sample, and wherein the lightness distribution results from an optical system of the microscopy device; and a correction section configured to correct, based on the information of lightness distribution acquired by the acquisition section, a lightness unevenness of a second image captured by the image sensor, wherein the second image is an image of the sample.
