  • Patent number: 10062183
    Abstract: For adjusting color values in image data for an emissive display, a method receives a frame of image data and adjusts a color value of a first color component by predetermined amount and identifies a white point from the adjusted color value of the first color component for each pixel in the frame of image data. The method remaps, for each pixel in the frame of image data, color values for a second color component and for a third color component based on the white point and controls the emissive display to present the frame of image data using the adjusted color value and the remapped color values. Each pixel of the emissive display includes a first subpixel that emits the first color component, a second subpixel that emits the second color component, and a third subpixel that emits the third color component.

    Abstract: Displaying wide-gamut images as intended on color-managed wide-gamut display systems while rendering a visually consistent image when rendered on targeted narrow-gamut display systems (regardless of whether the narrow-gamut displays are color-managed). Images represented in accordance with this disclosure are referred to as a dual-target images (DTI): one target being the image's original wide-gamut color space, the other target being a specified narrow-gamut color space. The novel representational scheme retains narrow-gamut rendering for those colors in a wide-gamut image that are within the targeted narrow-gamut color space, transitioning to wide-gamut rendering for those colors in the wide-gamut image that are outside the targeted narrow-gamut color space. This approach minimizes pixel clipping when rendering a wide-gamut image for a narrow-gamut display, while allowing the original wide-gamut pixel values to be recovered when rendering for a wide-gamut display.

  • Patent number: 10003485
    Abstract: A system for synchronizing lighting effect patterns of interactive lighting effect devices at a remote location with respect to those at local location is disclosed herein. Synchronized lighting effects produced at the remote location while watching a lighting effect show using other interactive lighting effect devices illuminated according to a script at event venue, can be achieved. Such synchronized lighting effects obtained at remote location generate a corresponding virtual simulated perception of attending same concert venue live when watching a live streaming video thereof. Low latency between lighting effect changes are produced at remote location with respect to those observed in concert venue live streaming video due to method of color control signal generation along with usage of color control pattern blending module that creates a blended video frame comprising of a color control pattern, which allows for efficient lighting effect pattern generation at remote location.
