IMAGING APPARATUS AND CONTROL METHOD THEREOF

PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of generating an image for which image blurring is corrected by geometrical deformation of a captured image even when the image is distorted by tilting, and a control method thereof.SOLUTION: An enlargement/reduction rate of a reference region and a focal distance of an optical system are calculated in such a manner that a reference region which is an image region required for generating an output image is settled within an image pickup region without changing an angle of view before and after geometrical correction. In the case where the calculated focal distance is less than a shortest focal distance of an optical system, which is corresponding to an estimated amount of camera shake of an image pickup apparatus and with which a tilting component can be corrected by geometrical deformation within such a range that the reference region does not exceed the image pickup region, the geometrical deformation is performed with such a geometrical deformation parameter as to obtain similar effects to the case where the focal distance of the optical system is changed to the calculated focal distance, without changing the focal distance of the optical system.
