  • Electro-optical filter
    Patent number: 7755720
    Abstract: The present invention provides an electro-optical filter for filtering light from an object. The filter is arranged for receiving the light via a first imaging element and comprises a plurality of reflective elements for receiving and reflecting the light. Each reflective element has an optical property that is dependent on an intensity of the light at or near the reflective element. The optical property controls local filtering of the light intensity in a manner such that, above a predetermined intensity threshold, the filter reduces intensity differences of light originating from bright and dark regions of the object.
