Abstract: A color enhancement system may enhance color components in an image. In one embodiment, the color enhancement system suppresses banding by combining an input color value with an enhanced colored value. In another embodiment, local variation in saturation values around a pixel may be used to determine a modification of an input saturation value for color enhancement. As still another embodiment, flickering between frames may be suppressed by combining a histogram that counts the number of times a given pixel value occurs in a particular image with a historical histogram that keeps track of an average of how often given values have occurred in previous frames.

Abstract: In some embodiments, a method includes receiving a plurality of video signal fields, characterizing at least one portion of at least one of the plurality of video signal fields, determining a value for a pixel using inter-field de-interlacing if the characterization satisfies a first criteria, determining a value for a pixel using motion compensated de-interlacing if the characterization satisfies a second criteria, and determining a value for a pixel using intra-field de-interlacing if the characterization satisfies a third criteria. In some embodiments, an apparatus includes a storage medium having stored instructions that when executed by a machine result in the method.

Abstract translation: 在一些实施例中，一种方法包括：接收多个视频信号字段，表征所述多个视频信号字段中的至少一个视频信号字段的至少一部分，如果所述表征满足所述视频信号字段的表征，则使用场间去隔行扫描确定像素的值 第一标准，如果表征满足第二准则，则使用运动补偿去隔行扫描确定像素的值，以及如果表征满足第三准则，则使用场内去隔行扫描确定像素的值。 在一些实施例中，装置包括具有存储的指令的存储介质，当由机器执行时，该指令产生该方法。

Abstract: Techniques related to compositing video content are discussed. Such techniques may include generating transparency data for a surface of first video content and storing it in a stream out buffer, accessing the transparency data via the stream out buffer when there is no change to the surface of the first video content, and compositing the first video content with second video content based on the accessed transparency data.
