  • Patent number: 11651530
    Abstract: Techniques are described for modification of color contrast ratio based on target contrast that overcome the challenges experienced in conventional systems for color contrast selection. In an implementation, a user leverages a content editing system to select a color set for contrast analysis. Utilizing the selected color set, the content editing system determines whether the color set exhibits a target contrast ratio. Further, the content editing system performs modification of the color set to generate candidate color sets that improve (e.g., increase) a contrast ratio of the original color set. The content editing system, for instance, manipulates color values (e.g., luminance values) of the original color set to increase a contrast ratio of the colors and generate different candidate color sets that are applicable to digital content.

    Abstract: Techniques are disclosed for converting image frames from one color space to another while predicting artistic choices that a director, colorist, or others would make. In one configuration, a color conversion application receives image frames, an indication of color spaces to convert between, and metadata associated with the image frames and/or regions therein. The conversion application determines a global, base color conversion for the image frames using a predefined color space transformation. Then, the conversion application (optionally) extracts image regions depicting objects of interest in the image frames, after which the color conversion application processes each of the extracted image regions and the remaining image frames (after the extracted regions have been removed) using one or more functions determined using machine learning. The processed extracted regions and remainders of the image frames are then combined by the color conversion application for output.

  • Patent number: 10068548
    Abstract: Systems and methods for improving perceived image quality of an electronic display, which includes a co-located sub-pixel that controls luminance of a first color component and an offset sub-pixel that controls luminance of a second color component. A display pipeline communicatively coupled to the electronic display determines image data, which indicates target luminance of the first, the second, and a third color component at an image pixel; determines edge parameters, which indicate whether an edge is expected to be present at the offset sub-pixel, based on a difference metric between a first image pixel block around the offset sub-pixel and a second image pixel block offset from the first image pixel block; and determines offset sub-pixel image data by filtering an image pixel group around the offset sub-pixel based at least in part on the edge parameters, wherein the offset sub-pixel image data indicates target luminance of the offset sub-pixel.

  • Patent number: 9736338
    Abstract: Corrected color components are obtained that correspond to an interpolation between a first and second corrected color component vector, in the first vector the color component are scaled to move a characteristic color component vector towards a target and in the second set the color components are contracted towards a reference determined by part of the color components. A position of the interpolation between the first and second corrected color component vectors is controlled by an interpolation coefficient computed from a ratio of an average value of the at least one of the color component in the input image or one or more reference images with similar content and an average obtained from the other color components of the input image or the or one or more reference images with similar content. The position of the interpolation is moved increasingly toward the second corrected color component vector with decreasing values of said ratio.
