1. A system for electronically capturing an image, comprising:
- a lens system for producing a distorted image;
an array of detectors for capturing the distorted image produced by the lens system;
a transmitter for transmitting said distorted image; and
a ground station for receiving the distorted image transmitted by said transmitter, said ground station capable of at least partially correcting said distorted image using image processing techniques.

Abstract
A lightweight camera is provided that includes a lightweight lens system that has a reduced number of lenses. Reducing the number of lenses produces a lighter camera, but produces a distorted local image. The distorted local image is captured by the lightweight camera, and is preferably transmitted to a remote station. The remote station then performs image processing on the distorted image to remove at least some of the distortion in the image. Preferably, a Massively Parallel Richardson-Lucy (MPRL) algorithm is used to identify and remove distortion from the image.
