Abstract
Official abstract text for this publication.
An image pickup apparatus performs image shake correction by driving a correction member which is movable for image shake correction. An image sensing device receives light focused by an imaging optical system and then photoelectrically converts the optical image into an image signal so as to output the image signal. An attitude sensor unit detects the attitude of the image pickup apparatus, and a drive control unit performs drive control of the correction member and position detection. A geometric deformation amount calculating unit decomposes distortion of an image into a first distortion component which varies due to the driving of the correction member and a second distortion component which does not vary due to the driving of the correction member so as to calculate correction values for the first and second distortion components. An image processing unit corrects the first and second distortion components by image processing based on the calculated correction values.
First claim
Opening claim text (preview).
What is claimed is: 1. An image pickup apparatus that corrects image shake by the driving of a correction member constituting an imaging optical system, the image pickup apparatus comprising: an image sensing device configured to receive an optical image focused by the imaging optical system so as to photoelectrically convert the optical image into an image signal; an attitude detecting unit configured to detect the attitude of the imaging optical system so as to output detectio…
