  • Publication number: 20220398710
    Abstract: Methods and systems for generating an image quality metric are described. A reference and a test image are first converted to the ITP color space. After calculating difference images ?I, ?T, and ?P, using the color channels of the two images, the difference images are convolved with low pass filters, one for the I channel and one for the chroma channels (I or P). The image quality metric is computed as a function of the sum of squares of filtered ?I, ?T, and ?P values. The chroma low-pass filter is designed to maximize matching the image quality metric with subjective results.

  • Patent number: 11277543
    Abstract: In a method for dithering image data, a processor receives an input image in a first color space and a first bit depth larger than 8 bits. The processor converts the input image into a first image in a perceptually uniform color space, such as the BT. 2100 ICtCp color space, with pixel values scaled to be within a target bit depth, it quantizes the first image to generate a quantized image, it generates an error image between the first image and the quantized image, and using a random threshold, it generates a dithered image based on the random threshold, the error image, and the quantized image, allowing to reduce the bit-depth representation for visually consistent reproduction by two bits.

  • Patent number: 11158032
    Abstract: Input scene images are captured from an original scene. The input scene images may be represented in an input color space. The input scene images are converted into color-space-converted scene images in one of an LMS color space, an ICtCp color space, etc. Scene light levels represented in the color-space-converted scene images are mapped, based at least in part on an optical transfer function, to mapped light levels. A tone mapping is applied to the mapped light levels to generate corresponding display light levels to be represented in display images. The display images may be rendered on a target display.

  • Publication number: 20210073954
    Abstract: The following provides a system and method to display images on a display screen (e.g. via a display panel or by projection) and the processing of image data therefor. In one aspect, the system implements a luminance retargeting method for altering the perceived contrast and/or colours of an image to match their appearance under different luminance levels. In another aspect, the system may provide a method for transforming an image locally within a sub-area of an image to adjust image contrast for display by a display device. In yet another aspect, the system may provide a method for transforming an image of a first luminance to adjust a perceived colour hue thereof for display by a display device according to a second luminance. In yet another aspect, the system may provide a method for transforming an image having a first luminance to adjust a colour saturation thereof for display by a display device having a second luminance.

  • Patent number: 10640672
    Abstract: The invention relates to an acrylic layer (in the form of a coating, film or sheet) useful as part of a photovoltaic module backsheet. The acrylic layer contains at least 40 percent of one or more acrylic polymers, including an acrylic polymer matrix and optionally acrylic impact modifiers. The acrylic polymer is preferably a polymer, copolymer, or terpolymer containing at least 50 weight percent of methylmethacrylate monomer units. The acrylic layer is flexible and optionally contains high levels of white pigment. It may also contain fluoropolymers such as polyvinylidene fluoride to improve weathering, processibility and film formation. The acrylic layer adheres to a polymer support layer such as polyethylene terephthalate (PET). A preferred substrate is PET that is pre-treated to improve adhesion, but unprimed PET can also be used. The backsheet provides excellent weatherability, environmental stability and reflectivity as part of a photovoltaic module.

  • Patent number: 10539290
    Abstract: The invention relates to optical light diffusers for use with point light sources, such as LED lighting. The optical diffusers achieve an optimum balance of light transmission and hiding power. The optical light diffuser is a transparent plastic matrix, such as Plexiglas® resin from Arkema Inc., having organic particles dispersed within the matrix. The particles are crosslinked beads having specific particle sizes and loading. Different beads can be combined to provide added properties such as a textured surface, and to optimize hiding power and light transmission. The invention also relates to a luminous device containing at least one light-emitting diode and a cover made of the optical light diffuser. The invention further relates to a method for assessing hiding power.

  • Patent number: 10140953
    Abstract: Methods are disclosed for adaptive display management using one or more viewing environment parameters. Given the one or more viewing environment parameters, an effective luminance range for a target display, and an input image, a tone-mapped image is generated based on a tone-mapping curve, an original PQ luminance mapping function, and the effective luminance range of the display. A corrected PQ (PQ?) luminance mapping function is generated according to the viewing environment parameters. A PQ-to-PQ? mapping is generated, wherein codewords in the original PQ luminance mapping function are mapped to codewords in the corrected (PQ?) luminance mapping function, and an adjusted tone-mapped image is generated based on the PQ-to-PQ? mapping.

  • Patent number: 9988527
    Abstract: The invention relates to impact-modified, thermoplastic compositions, where the measured refractive index difference between the impact modifier particles and the matrix composition is greater than 0.008 units, yet a blend of the impact modifier particles in the matrix produces a transparent composition. The impact modifier particles are preferably impact modifier composite particles, being intimately blended with one or more polymeric process aids or dispersing aids. The polymeric process aids are physically or chemically attached to the impact modifier particles, forming composite particles that allow for facile powder isolation. The impact modifier composite particles provide improved physical, chemical, and/or rheological properties to the thermoplastic composition. Preferably the impact modifier particles of the invention are core-shell impact modifiers.

  • Publication number: 20120024353
    Abstract: The invention relates to high Tg monolithic and multi-layer thermoformable film or sheet useful as a backsheet on a photovoltaic module (PV). A methacrylic-based material is preferred. The film or sheet is formed of a composition having a Tg greater than 110┬░ C. The methacrylic composition may be a blend of a polymethyl methacrylate polymer and a miscible or semi-miscible high Tg polymer, or may be a copolymer containing primarily methyl methacrylate monomer units. The backsheet is optionally covered with a fluoropolymer or acrylic/fiuoropolymer covering on the outside (side facing the environment). The back-sheet can be clear, white, and/or pigmented. The film or sheet is especially useful in concentrating photovoltaic modules (CPV), and is also useful in thin film photovoltaic modules.
