Filter for enhancing vision and/or protecting the eyes and method of making a filter

The selective filtering of light by polarization interference may be used to enhance vision and / or protect eyes from harmful light rays. For example, such filtering may be used in sunglasses, color corrective eyewear or protective eyewear. The selective filtering of incident light may provide any desired spectral transmission (including visible light and light not visible to the eye) and is performed by a pair of polarizing elements that sandwich a retarder stack. The filtering structure may be formed by multi-layer polarizing structures and may be formed by fabricating sheet laminates that are die cut to form inexpensive laminates. The laminates may be flat or curved in one (e.g., wrap-around) or more dimensions.

Polarized contrast enhancing sunglass lens

InactiveUS7597441B1Promotes accurate color perceptionHigh light transmittanceSpectales/gogglesOptical partsUv spectrumUltraviolet
The invention is a polarized sunglass lens that utilizes a multiband contrast enhancer comprised of three rare-earth oxides to provide relatively high peak transmittance in portions of the red and green spectrum, relatively lower transmittance for the blue spectrum, and very low transmittance for the UV spectrum. The lens provides enhanced perception of colors, heightened contrast, and improved visual acuity. The inclusion of vanadium pentoxide in the lens provides attenuation of the UV spectrum, thus protecting the user's eyes and the internal layers and colorants from UV-induced damage. The front lens element can be either the multiband contrast enhancer or a photochromic lens element.

Legibility Enhancement for a Logo, Text or other Region of Interest in Video

A video processing system enhances quality of an overlay image, such as a logo, text, game scores, or other areas forming a region of interest (ROI) in a video stream. The system separately enhances the video quality of the ROI, particularly when screen size is reduced. The data enhancement can be accomplished at decoding with metadata provided with the video data for decoding so that the ROI that can be separately enhanced from the video. In improve legibility, the ROI enhancer can increase contrast, brightness, hue, saturation, and bit density of the ROI. The ROI enhancer can operate down to a pixel-by-pixel level. The ROI enhancer may use stored reference picture templates to enhance a current ROI based on a comparison. When the ROI includes text, a minimum reduction size for the ROI relative to the remaining video can be identified so that the ROI is not reduced below human perceptibility.
