1. An image capturing apparatus, comprising:
an image sensor configured to change an exposure condition for each of a plurality of exposure areas, each of the exposure areas including a single pixel or a plurality of pixels, wherein the exposure condition includes at least one of an exposure time or an analog gain; and
an image processing unit configured to perform digital signal processing on a signal of a captured image, the digital signal processing comprising:
generating a plurality of coupled areas in which the exposure areas are coupled based on a first threshold of the exposure condition,
calculating a parameter for each of the coupled areas, the parameter being used to correct the captured image, and
correcting the captured image, based on the parameter, for each of the exposure areas.
