摘要： A method (400) and a system (100) for providing video signals to video displays includes the steps of receiving at least one input video signal (150), dithering the non-uniformity color correction (445), applying the non-uniformity color correction to the input video signal to generate a color corrected video signal (450), and increasing a frame rate of the color corrected video signal (120). Gamma correction (125) can be applied to the color correction. Generating a dithered non-uniformity color correction can include selecting from a data storage (115) a plurality of RGB correction matrices (300), measuring at least one brightness level of the input video signal, selecting for the picture level correction a first RGB correction matrix if the brightness is within a first range of values (425), a second RGB correction matrix if the brightness is within a second range of values (435), and interpolating (440) the plurality of RGB correction matrices if the brightness is within a third range of values.
摘要翻译：一种用于向视频显示器提供视频信号的方法（400）和系统（100）包括以下步骤：接收至少一个输入视频信号（150）;抖动不均匀颜色校正（445）;将不均匀颜色校正输入视频信号以生成色彩校正的视频信号（450），并且增加色彩校正的视频信号（120）的帧速率。伽玛校正（125）可以应用于颜色校正。生成抖动的不均匀颜色校正可以包括从数据存储器（115）中选择多个RGB校正矩阵（300），测量输入视频信号的至少一个亮度级，为图像级校正选择第一RGB校正矩阵，如果亮度在第一值范围内（425），则如果亮度在第二值范围内（435）则为第二RGB校正矩阵，并且如果亮度在范围内，则内插（440）多个RGB校正矩阵第三个数值范围。
