An apparatus includes an imaging unit configured to acquire an image, a drive unit configured to drive the imaging unit, a control unit configured to control the drive unit, a detection unit configured to detect a blur of the acquired image, a correction unit configured to correct the detected blur of the image, an acquisition unit configured to acquire a drive velocity at which the drive unit drives the imaging unit, and a setting unit configured to set the detection unit. The setting unit sets the detection unit such that in a case where the drive velocity is in a resonance velocity range in which resonance occurs in the imaging unit, the detection unit detects the blur of the image at a first frequency band corresponding to a blur due to the resonance.
