1. An information processing apparatus comprising:
at least one processor, a memory coupled to the at least one processor, the memory storing instructions that, when executed by the processor, cause the processor to function as:
an acquisition unit configured to acquire a captured image;
a first detection unit configured to detect a subject from the image acquired by the acquisition unit;
a second detection unit configured to detect a part of the subject from an image acquired by the acquisition unit; and
a determination unit configured to determine exposure based on a luminance of the subject detected by the first detection unit to decrease a difference between the luminance of the subject and a first luminance which is a target luminance of the subject, and subsequently determine exposure based on a luminance of the part of the subject detected by the second detection unit under the exposure determined based on the luminance of the subject detected by the first detection unit to decrease a difference between the luminance of the part of the subject and a second luminance which is a target luminance of the part of the subject, the second luminance being different from the first luminance, wherein the determination unit increases a difference between the first luminance and the second luminance, in a case where the part of the subject is not detected by the second detection unit from an image captured based on the exposure determined for the subject.
