Abstract
An imaging apparatus includes an imaging unit configured to convert an object image into an image signal, a vibration detection unit configured to detect a vibration and output information about the vibration, a correction unit moving in a plane orthogonal to an optical axis configured to correct the vibration, a target position calculation unit configured to calculate a target position to which the correction unit is moved based on the information about the vibration output from the vibration detection unit, a position detection unit configured to detect a present position of the correction unit, a calculation unit configured to calculate a difference between the present position and the target position, and a determination unit configured to determine whether a force acting on the imaging apparatus is a gravitational force based on the information about the vibration and a cycle of the vibration.
