Imaging apparatus for stabilizing an image

An imaging apparatus including an image sensor and a correction optical member movable in a direction perpendicular to an optical axis, the imaging apparatus comprising:

• a vibration detection unit configured to detect a vibration of the imaging apparatus;
• 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 setting unit configured to set a gain of the amplifier unit based on the motion vector;
• an imaging condition detection unit, which includes a temperature sensor, configured to detect a change of an imaging condition wherein the imaging condition detection unit detects the change of the imaging condition when a temperature measured by the temperature sensor changes between a temperature before use and a temperature during use of the imaging apparatus and when a difference between the temperature before use and the temperature during use is greater than or equal to a predetermined temperature;
• a counter configured to increase a time count;
• a gain control unit configured to stop the setting unit from setting the gain of the amplifier unit when a gain adjustment value coefficient is less than or equal to a predetermined value and when the time count is greater than or equal to a predetermined time after starting the gain control,
• wherein the gain control unit starts the gain control when the imaging condition detection unit detects the change of the imaging condition, and clears the time count when the gain adjustment value coefficient is larger than a predetermined value;
• and
• a vibration correction unit configured to drive the correction optical member to correct an image vibration according to an output from the vibration detection unit,
• 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 gain control unit does not stop setting of the gain of the amplifier.
