Abstract
A method, computer-usable medium and a system for varying an incoming light field are disclosed. Embodiments provide mechanisms for performing image processing on an incoming light field using a spatial light modulator which is adjusted based upon characteristics of the incoming light field. The spatial light modulator may be positioned between the viewed scene and the eye, and therefore, may be semi-transparent. The image processing may consist of tone mapping, color enhancement, beautification, edge enhancement, spectral separation of colors, spectral separation of metamers, object emphasis, other image processing, or some combination thereof. Additionally, embodiments compensate for parallax errors by adjusting the spatial light modulator based upon the position of an observer with respect to the spatial light modulator. And further, embodiments may be incorporated into optical devices, wearable optical devices, windows, windshields, and the like, where the semi-transparent spatial light modulator adjusts the image before entering the eye.
