Abstract
An imaging apparatus with an image sensor and a correction optical system movable in a direction perpendicular to an optical axis includes a vibration detection unit configured to detect a vibration applied to the imaging apparatus, a vibration correction unit configured to drive the correction optical system to correct an image vibration according to an output from the vibration detection unit, a motion vector detection unit configured to detect a motion vector based on an image signal output from the image sensor, an amplifier unit configured to amplify the output from the vibration detection unit, a gain setting unit configured to set a gain of the amplifier unit based on the motion vector; and a gain control unit configured to allow or inhibit the setting of the gain of the amplifier unit set based on the motion vector, according to a change of an imaging condition of the imaging apparatus, wherein the vibration correction unit performs a vibration correction based on the output from the vibration detection unit and the gain of the amplifier unit when the setting of the gain of the amplifier unit is allowed by the gain control unit.
