1. An electronic device comprising:
a power converter;
a camera module comprising a camera;
at least one processor; and
memory storing instructions that, when executed by the at least one processor individually or collectively, cause the electronic device to:
identify a first illuminance value of a surrounding of the electronic device in a state in which a switching frequency of the power converter transferring power to the camera module is a first frequency;
determine that the first illuminance value meets a first reference based on a state in which the first illuminance value is a first reference value or less being maintained for a first time; and
set the switching frequency of the power converter to a second frequency different from the first frequency based on the first illuminance value meeting the first reference.
