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

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. Also, motion, temperature and inter-detector difference distortion is detected and corrected.

What is claimed is: 1. A lightweight camera and system comprising: a camera comprising: at least one lens having a nonplanar focal plane; a substantially planar infrared detector array situated proximate to the nonplanar focal plane of said lens; a motion detector for detecting motion of the camera

What is claimed is: 1. A lightweight camera and system comprising: a camera comprising: at least one lens having a nonplanar focal plane; a substantially planar infrared detector array situated proximate to the nonplanar focal plane of said lens; a motion detector for detecting motion of the camera; and a transmitter connected to said detector array and said motion detector; a receiver for receiving wireless signals from said transmitter; and a processor connected to said receiver; wherein: an image detected by said detector has some nonplanar-to-planar focal plane distortion and said detector has some motion relative to a source of the image resulting in some forward translation of camera blur of the image detected by said detector array; said motion detector has an output providing an indication of an amount of forward translation of camera blur; and said processor reduces the distortion. 2. The camera and system of claim 1, wherein said processor reduces forward translation of camera blur of the image detected by said detector array. 3. The camera and system of claims 2, further comprising: a temperature sensor situated on said detector array and connected to said transmitter; and a model having temperature data for the detector array connected to said processor; and wherein a detector array temperature from said transmitter is adjusted according to temperature data of said model. 4. The camera and system of claim 3 wherein: said receiver receives individual detector values; and said processor normalizes the detector values when the individual detectors output different values for the same radiation detected. 5. The camera and system of claim 4, wherein said processor reduces the effects in the image caused by lens defects. 6. The camera and system of claim 5, wherein: said camera has a weight less than 15 grams; and said receiver is situated on the ground.
