System and Method for Constructing a Motion-Compensated Composite Image
First Claim
1. A method for constructing a motion-compensated composite image of a scene, the method comprising:
- (i) acquiring a plurality of images of a scene over time, the plurality of images including an earlier image of the scene and a later image of the scene;
(ii) estimating relative motion between the earlier and later images;
(iii) computing an exposure parameter value based upon the relative motion estimated between the earlier and later images;
(iv) acquiring, using the computed exposure parameter value, a new image of the scene; and
(v) compositing the earlier, later and new images of the scene to produce a motion-compensated composite image of the scene.

Abstract
A method for constructing a motion-compensated composite image of a scene includes acquiring a plurality of images of a scene over time, the plurality of images including an earlier-acquired image of the scene and a later-acquired image scene. The relative motion between the earlier and later acquired images are estimated, and an exposure parameter is computed based upon the estimated relative motion occurring between the earlier and later acquired images. A new image of the scene is acquired using the computed exposure parameter, and the earlier, later, and newly acquired images are combined to produce a motion-compensated composite image of the scene.
