Abstract

An imaging platform minimizes image distortion when there is relative motion of the imaging platform with respect to the scene being imaged where the imaging platform may be particularly susceptible to distortion when it is configured with a wide field of view or high angular rate of movement, or when performing long-stares at a given scene (e.g., for nighttime and low-light imaging.) Distortion correction may be performed by predicting distortion due to the relative motion of the imaging platform, determining optical transformations to prevent the distortion, dynamically adjusting the optics of the imaging platform during exposure, and performing digital image correction.

First claim

What is claimed is:

1. A system configured to capture images, comprising:
an imaging platform configured to capture an image of a scene during an exposure period, the image being represented as a plurality of sub-frames;
a distortion prediction processor configured to determine transformations to prevent image distortion caused by a relative motion between the scene and the imaging platform, and to determine residual transformations to correct residual image distortion;
a cont…
