    Abstract: Source content super-sampled to a first resolution in an extended range space is obtained. A representation of a subpixel geometry of a display panel displaying the source content is obtained. The display panel includes, for every pixel, plural subpixel elements for three or more color primaries. A native resolution of the display panel is lower than the first resolution of the source content. An optimization operation is performed based on a set mode of the display panel and the representation of the subpixel geometry to derive a global optimization for determining, for a given pixel value based on the source content, an energy distribution between the plurality of subpixel elements of a corresponding pixel of the display panel. The source content in the extended range space is converted into intermediate content in a display space based on the global optimization. The intermediate content is further optimized based on error minimization.

    Abstract: A method and user interface for direct setting of black and white points. Black point is set using a slider and matching of gray shades. White point setting is performed by having a setting object move within a defined region, such as a square or circle, with the area where the setting object moves being adjusted dynamically based on the location of the setting object with respect to the defined region. When the area is the desired white, the setting is complete. Preferably the defined region has a varying color border to allow a reference for the user in moving the setting object. A more detailed setting of gray levels can be accomplished by providing a gray scale with reference points. Each reference point has an associated white point setting area, so that settings are developed for each reference point. Settings at other locations are determined by interpolation or extrapolation.

    Abstract: A display device is used in conjunction with: (1) optical sensors to collect information about ambient conditions in the environment of a viewer of the display device; and/or (2) privacy element identification and detection mechanisms (PEDMs) to collect information about the presence, orientation, and/or type of privacy elements being used in conjunction with the display device. For one embodiment, a processor in communication with the display device may create a view model based, at least in part, on the predicted effects of the ambient environmental conditions and/or presence of privacy elements being used in conjunction with the display device on the user's viewing experience. The view model may be a function of gamma, black point, white point, privacy element orientation and/or type, backlighting, field of view, number of viewers, color offset, or a combination thereof. The view model is also referred to as an ambient/privacy model.

    Abstract: Several methods, devices and systems for correcting rolling shutter artifacts are described. In one embodiment, an image capturing system includes a rolling shutter image sensor that may cause a rolling shutter artifact (e.g., warping). The system includes a processing system that is configured to perform an automatic rolling shutter correction mechanism that utilizes calibration data based on a relationship between pixel locations in an image plane of the image sensor and their corresponding rays of light in a coordinate space. The rolling shutter mechanism determines pixel velocity components based on the calibration data and estimates for each image an aggregate pixel velocity based on an aggregation of the pixel velocity components.

    Abstract: Methods and apparatus for rendering and displaying high dynamic range (HDR) digital image content. An HDR rendering and display system may support the rendering and display of standard dynamic range (SDR) and HDR content to both HDR-enabled and standard displays. The HDR rendering and display system renders digital image content into the HDR space and maps the rendered HDR content into the display space of HDR or standard displays using display processing techniques that may preserve at least some of the HDR content even for standard displays. The HDR rendering and display system may take into account various information including but not limited to display characteristics such as size, control inputs, current image characteristics such as image brightness, and environmental information such as viewer position and ambient lighting levels to dynamically adapt the rendering and display of the digital image content according to ambient viewing conditions at the target display.

    Abstract: Adaptive video processing for a target display panel may be implemented in or by a server/encoding pipeline. The adaptive video processing methods may obtain and take into account video content and display panel-specific information including display characteristics and environmental conditions (e.g., ambient lighting and viewer location) when processing and encoding video content to be streamed to the target display panel in an ambient setting or environment. The server-side adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to generate video content in the color gamut and dynamic range of the target display panel that is adapted to the display panel characteristics and ambient viewing conditions.

    Abstract: An output device is set to a first state in which a value of a first characteristic of the output device is set to a first value. Pixel adjustment values for plural gray levels are set to first pixel adjustment values in response to the output device being set to the first state. The value of the first characteristic is changed from the first value to a second value to set the output device to a second state. The pixel adjustment values for the plural gray levels are updated to second pixel adjustment values in response to the output device being set to the second state. The second pixel adjustment values are derived based on the second value of the first characteristic. Pixel values applied to a plurality of pixels of the output device are corrected based on the second pixel adjustment values.
