Abstract
An apparatus includes a detection unit configured to detect a flicker frequency of a subject light source by sampling an output signal of a sensor in first sampling processing, a determination unit configured to determine whether the detected flicker frequency falls within a detection target range, by sampling an output signal of the sensor in second sampling processing, and a control unit configured to perform control to notify a user in response to determination by the determination unit that the detected flicker frequency falls out of a detection target range in the first sampling processing.
