1. An apparatus comprising:
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 function as:
an acquisition unit configured to acquire a first control value related to white balance based on an input image;
a determination unit configured to determine whether a first area including the acquired first control value is changeable;
a control unit configured to change the first area to a second area based on whether the first area including the acquired first control value is changeable; and
a calculation unit configured to calculate a second control value related to the white balance to be applied to the input image in the second area in a case where the first area is changed to the second area,
an estimation unit configured to estimate influence of an infrared light component in the input image,
wherein the determination unit determines whether the first area is changeable based on the estimated influence of an infrared light component, and
wherein the first area is changed to the second area by stages.
