摘要： A process for reducing noise and temporal artifacts (e.g. walking LEDs) on a dual modulation display system by applying temporal filtering to rear modulation signals of a sequence of video frames. Flare and dimming rates are calculated for a current frame in the video. If a flare rate threshold is exceeded, an intensity of the backlight is limited to a predetermined flare rate. If a dimming rate threshold is exceeded, the backlight intensity is limited to a predetermined dimming rate. The limitations are applied, for example, on an element-by-element basis. In the event of a scene change, the limitations do not need to be applied. A forward modulation signal is calculated by taking into account any applied backlight limitations.
摘要翻译：一种通过对视频帧序列的后调制信号应用时间滤波来减少双调制显示系统上的噪声和时间假象（例如步行LED）的过程。为视频中的当前帧计算耀斑和调光率。如果超过光斑速率阈值，则将背光的强度限制在预定的扩张率。如果超过了调光率阈值，则将背光强度限制在预定的调光速率。这些限制例如在逐个元素的基础上被应用。在场景变化的情况下，不需要应用限制。通过考虑任何应用的背光限制来计算正向调制信号。

摘要： Source image content is adapted to a target display. Target image content associated with the target display is provided. A histogram is computed for the target image content. A prominent feature present in the target histogram is determined. A histogram is computed for the source image content. The source content histogram is manipulated to reflect the determined target histogram prominent feature(s). Adapted source image content is generated based on the manipulated source histograms(s). Another prominent feature present in the target histogram is determined. The source histogram is further manipulated to reflect the other prominent determined target histogram features. Further adapted source image content is generated based on the further manipulated source histogram if the adapted source image content has insufficient image quality and perceptual color characteristics.

摘要： Embodiments relate generally to computer-based image processing, and more particularly, to systems, computer-readable media, methods, integrated circuits, and apparatuses to facilitate operation of a projection system with relatively high dynamic range output by, among other things, providing subsets of light patterns along an optical path during respective first and second temporal fields associated with respective first and second illuminants. The projection system can synthesize color for projectable images by combining or otherwise using the subsets of light patterns with an array of color elements to produce projectable images with color in at least the visible spectrum.

摘要： Embodiments relate generally to image and display processing, and more particularly, to systems, apparatuses, integrated circuits, computer-readable media, and methods that detect light sources in images to facilitate the prediction of the appearance of color for the images in different viewing environments and/or dynamic range modification based on the light sources (e.g., perceived light sources). In some embodiments, a method includes detecting pixels representing a portion of an image, specifying that a subset of pixels for the image portion is associated with a light source, and determining a parameter for the subset of pixels, the parameter being configured to generate a color in a reproduced image that includes the image portion. In one embodiment, light sources are detected to facilitate converting between high dynamic ranges and low dynamic ranges of luminance values.
