Image sensing apparatus with camera shake correction function
First Claim
1. An image sensing apparatus which has a camera shake correction function of performing a camera shake correction on a plurality of images sensed by an image sensing unit by extracting a partial image from each of the sensed images on the basis of correlation between the sensed images, comprising:
- a drive unit that exposes the image sensing unit and reads out image signals at predetermined period;
a first control unit that outputs each of the image signals read out at the predetermined period as one image; and
a second control unit that adds image signals sensed during latest n (n is a natural number not less than
2) periods while performing a camera shake correction on the image signals read out at the predetermined period, and outputs the sum image signal as one image at the predetermined period.

Abstract
In an image sensing apparatus which has a camera shake correction function of performing a camera shake correction on a plurality of images sensed by an image sensing unit by extracting a partial image from each of the sensed images on the basis of correlation between the sensed images, the image sensing unit is exposed, and image signals are read out at predetermined periods. The image sensing apparatus selectively outputs either each of the image signal read out at the predetermined period as one image, or each of image signals obtained by adding image signals for latest n (n is a natural number not less than 2) periods while performing a camera shake correction on the image signals read out at the predetermined period, and the sum image signal as one image.
