Abstract

When correcting rotary shake, an area to be referenced when distortion aberration correction is performed is rotated by a detected rotation amount in a direction correcting the rotary shake, such that the reference area fits into the area of an image that has been captured. A rectangular image of the same size as the captured image is obtained by applying distortion aberration correction to an image included in the reference area. If the reference area will not fit into the area of the captured image when rotated by the detected rotation amount, the reference area is rotated by a maximum angle at which the reference area will fit into the area of the captured image, and distortion aberration correction is applied to the image included in the reference area. Information on the captured angle of view can thereby be effectively used when performing distortion aberration correction and rotary shake correction.

First claim

What is claimed is:

1. An imaging apparatus comprising:
an imaging unit configured to output an image captured via an imaging optical system;
a detection unit configured to detect rotary shake of the imaging apparatus, where the rotation axis of the rotary shake is an optical axis of the imaging optical system; and
an image processing unit configured to perform image processing;
wherein the image processing unit comprises:
a rotary correction unit configured to set a refer…
