Abstract:
1. An imaging apparatus comprising: 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; wherein the determination unit determines that the force acting on the imaging apparatus is the gravitational force when the difference changes, if the information about the vibration is equal to or less than a predetermined value, or even if the information about the vibration is greater than the predetermined value but the cycle of the vibration is equal to or smaller than predetermined time.
