Claim Text:
1. An image processing apparatus for performing image processing for an image captured by an image capturing apparatus including an image capturing unit configured to change, between lines, a timing to receive light of an object image formed by an imaging optical system and accumulate charges, a shake detection unit configured to detect a shake, and an image stabilization unit configured to optically correct an image blur caused by the shake based on an output of said shake detection unit, comprising: a storage unit configured to store the image captured by the image capturing apparatus, information of the shake, and a position of the image stabilization unit when capturing the image; a distortion correction amount calculation unit configured to calculate, based on the information of the shake stored in said storage unit, a distortion correction amount used to correct a rolling shutter distortion caused in the image by the shake during charge accumulation period of said image capturing unit; and a correction unit configured to correct the image stored in said storage unit based on the distortion correction amount, wherein said distortion correction amount calculation unit calculates the distortion correction amount using, as a reference, a position set based on the position of said image stabilization unit stored in said storage unit.
