    摘要: Discloses herein are methods, apparatuses, and systems for preparing and displaying images in frame-sequential stereoscopic 3D. Frame-sequential stereoscopic display includes an alternating sequence of left- and right-perspective images for display. Disclosed methods include identifying pixels that modulate due to the alternating sequence of left- and right-perspective images of the frame-sequential stereoscopic display. The disclosed methods also include processing the pixels to reduce one or more residual images caused by the alternating sequence of left- and right-perspective images of the frame-sequential stereoscopic display. The disclosed methods may be implemented by a processing unit and the processing unit may be included in a system (such as, a computer or video-game console).

    摘要: A de-interlacer includes recursive motion history map generating circuitry operative to determine a motion value associated with one or more pixels in interlaced fields based on pixel intensity information from at least two neighboring same polarity fields. The recursive motion history map generating circuitry generates a motion history map containing recursively generated motion history values for use in de-interlacing interlaced fields wherein the recursively generated motion history values are based, at least in part, on a decay function.

    摘要: A method and apparatus for independent video and graphics scaling in a video graphics system is accomplished by receiving a video data stream, wherein the video data stream includes video data in a first format. A graphics data stream is also received, and the graphics data stream includes graphics data in a second format. The video data of the video data stream is scaled based on a ratio between the first format and a selected video format to produce a scaled video stream. Similarly, the graphics data of the graphics data stream is scaled based on a ratio between the second format and a selected graphics format in order to produce a scaled graphics stream. The scaled video stream and the scaled graphics stream are then merged to produce a video graphics output stream.

    摘要: An improved deinterlacing technique reconstructs regions of an image that change monotonically in the vertical direction (i.e., vertical deinterlacing). The present invention adapts to the image content without using spatio-temporal interpolation techniques. Rather, deinterlacing in accordance with the teachings of the present invention uses, for example, four localized input pixel values to produce an output pixel value that minimizes spatial artifacts (i.e., accurately reconstructs regions that change monotonically in the vertical direction). In another embodiment, an overlay scaler shares overlay scaling circuitry and deinterlacing circuitry to provide a cost effective implementation of a unique deinterlacing circuit. In another embodiment, a plurality of offsets are used in addition to three or more pixels.

    摘要: A method and apparatus adaptively creates a dropped frame rate converted frame from a plurality of source frames using at least one alternate support frame in lieu of a neighboring source frame, in response to corrupted picture identification information. Stated another way, a frame rate converter, in response to corrupted picture indication information, replaces at least one corrupted source frame with a temporally modified frame created from at least one alternate source frame. The corrupted picture identification information indicates that a source frame, or segment thereof, includes at least one corrupted or dropped source frame (or segment thereof).

    摘要: A method and apparatus is disclosed for using multiple scalers to scale video and graphics data. A video data is capable of accessing data formats not accessible by a graphics engine, pipeline, or scaler. The video data can be accessed by the video scaler and subsequently converted to a data format accessible by the graphics engine, pipeline or scaler. The converted video data can be routed to memory. Once stored in memory, the data can be accessed for further processing, such as additional scaling or graphics processing. In addition, the converted video data can be output directly to a processor, such as a graphics processor for additional processing.
