1. An image processing apparatus comprising:
one or more processors; and
at least one memory, the at least one memory being coupled to the one or more processors and having stored thereon instructions executable by the one or more processors, wherein the execution of the instructions cause the image processing apparatus to function as:
an acquisition unit configured to acquire a captured image obtained by capturing an object;
a specifying unit configured to specify a region including in at least part of the object in the captured image; and
a generation unit configured to generate a correction image in which brightness of at least part of the specified region in the captured image is changed using pixel values of pixels in the captured image,
wherein the generation unit generates the correction image so that a first region of the specified region in the correction image has stronger shade than a second region of the specified region in the correction image, the first region being different from the second region,
wherein a degree of change of brightness of a first pixel from the captured image to the correction image is different from a degree of change of brightness of a second pixel from the captured image to the correction image,
wherein the first pixel and the second pixel are included in the specified region, and
wherein a distance from an imaging device at the first pixel is equal to a distance from the imaging device at the second pixel, and a normal direction corresponding to the first pixel is different from a normal direction corresponding to the second pixel.
