Classification: CPC H  G | IPC G  H

Claim 0:
1. An apparatus comprising:
an image sensor that captures a subject through an optical system, wherein the image sensor can set an exposure time or gain for each of pixel groups individually;
at least one processor; and
a memory coupled to the at least one processor, the memory storing instructions that, when executed by the at least one processor, cause the at least one processor to:
acquire information about a specific image region in an image captured by the image sensor;
determine a specific pixel region corresponding to the specific image region, based on the information about the specific image region;
change at least one of a number, a size, and a shape of pixel groups in the determined specific pixel region so that the number of pixel groups becomes smaller than a predetermined value; and
control the exposure time or gain for each of the changed pixel groups individually.
