Abstract:
1. An image sensing apparatus including an image sensor driven by a rolling shutter method, comprising: a detection unit configured to detect a shake of the image sensing apparatus in an exposure period of the image sensor when sensing an image using the image sensor; an obtaining unit configured to obtain a temporal characteristic of the shake detected by said detection unit; an analysis unit configured to analyze, for the temporal characteristic of the shake, a frequency distribution of a distortion amount of an object image that is generated in the image owing to the shake; a determination unit configured to determine, as a center frequency of the distortion amount from the frequency distribution of the distortion amount, a frequency at which the distortion amount becomes relatively maximum; a compensation unit configured to compensate for the temporal characteristic of the shake to reduce a phase shift generated by said obtaining unit for at least the center frequency; and a correction unit configured to correct an object image distortion arising from the shake for each line of the image sensor by using a correction amount calculated from the shake compensated for by said compensation unit.
