Abstract
An imaging apparatus includes a panning driver and a tilting driver for changing an imaging direction. A PT (pan-tilt) controller performs image blur correction by using at least one of a panning driver and a tilting driver, based on a shake detection signal of the imaging apparatus. The PT controller stores the position information of the current driver in a memory before each driver is driven in an image blur correcting start process. With the stored position as a reference position, image blur correction is performed by using the shake detection signal. After the end of the image blur correction control, the PT controller sets the position stored in the memory to the drive target value and controls the operation of each driver.
Claims15
An imaging apparatus comprising:
- an imaging unit configured to include an imaging optical system and an image sensor;
- a driver configured to hold the imaging unit and change an imaging direction of the imaging unit;
- a memory configured to store position information of the driver;
- and
- a controller configured to perform image blur correction of an image acquired by using the imaging unit by acquiring a detection signal from a detection unit that detects a shake and controlling the driver,
- wherein, when the controller starts the image blur correction, the controller performs the image blur correction by storing a position of the driver in the memory before driving the driver and using the detection signal with the position stored in the memory to serve as a reference position.
A control method executed in an imaging apparatus that enables image blur correction of an image obtained by using an imaging unit including an imaging optical system and an image sensor, the method comprising:
- storing position information of the driver that holds the imaging unit and changes an imaging direction of the imaging unit;
- and
- performing image blur correction of an image obtained by using the imaging unit by acquiring a detection signal from a detection unit that detects shaking and controlling the driver, and
- wherein, when the image blur correction starts, the image blur correction is performed by storing a position of the driver in a memory before the driver is driven, and using the detection signal with the position stored in the memory to serve as a reference position.
