Abstract
The present invention is directed to a system, which uses polarized light difference to improve vision. The system obtains an image at a first polarization direction. The system then obtains an image at a second orthogonal polarization direction. The second orthogonal polarization value is subtracted from the first value. The difference value is then amplified in order to provide an enhanced image.
