SHADING CORRECTION METHOD FOR IMAGE CAPTURING APPARATUS, AND IMAGE CAPTURING APPARATUS

摘要

An image shading correction method for an image capturing apparatus, comprising an obtaining step of obtaining a first image signal of an image captured of an area having a uniform luminance distribution using another image capturing apparatus that is different from the image capturing apparatus under a first condition, a second image signal of an image captured of the area having a uniform luminance distribution using the other image capturing apparatus under a second condition, and a third image signal of an image captured of the area having a uniform luminance distribution using the image capturing apparatus under the first condition, and a correction step of performing, based on the first to third image signals, correction processing on an image of an object captured using the image capturing apparatus under the second condition.
