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 adaptively creates a dropped frame rate converted frame from a plurality of source frames using at least one alternate support frame in lieu of 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). Accordingly, although a source frame has been dropped or is corrupted, the frame rate converter does not base its output on a repeated frame or a corrupted frame output by a decoder and instead utilizes other non-neighboring source images as though they were neighboring frames, instead of using a repeated frame or corrupted frame.
摘要翻译：响应于损坏的图像识别信息，方法和装置使用至少一个替代支持帧代替相邻源帧从多个源帧自适应地创建丢弃的帧速率转换帧。换句话说，帧速率转换器响应于损坏的图像指示信息，用至少一个替代源帧创建的具有时间上修改的帧替换至少一个损坏的源帧。损坏的图像识别信息指示源帧或其片段包括至少一个损坏或丢弃的源帧（或其片段）。因此，虽然源帧已经被丢弃或被破坏，但是帧速率转换器不将其输出设置在由解码器输出的重复帧或损坏的帧上，而是使用其他非相邻源图像，就像它们是相邻帧一样，而不是使用重复的帧或损坏的帧。

摘要： Circuitry for better integrating multiview-based 3D display technology with the human visual system includes logic that identifies an object of interest from a plurality of objects in a multiview-based 3D scene displayed on one or more displays and provides focus adjustment control data for eyewear to view the 3D scene based on perceived distance data corresponding to the identified at least one object of interest and the identified at least one object of interest. In one example, the circuitry includes logic that determines the perceived distance data corresponding to the at least one object of interest based on inter-object distance data indicating a horizontal offset between the at least one object of interest in a first scene view and the same at least one object of interest in a second scene view and display distance data indicating the distance between one or more display screens and a viewing position. Related methods are also set forth.

摘要： A method for deinterlacing interlaced video using a graphics processor includes receiving at least one instruction for a 2D/3D engine to facilitate creation of an adaptively deinterlaced frame image from at least a first interlaced field. The method also includes performing, by the 2D/3D engine, at least a portion of adaptive deinterlacing based on at least the first interlaced field, in response to the at least one instruction to produce at least a portion of the adaptively deinterlaced frame image. Once the information is deinterlaced, the method includes retrieving, by a graphics processor display engine, the stored adaptively deinterlaced frame image generated by the 2D/3D engine, for display on one or more display devices. The method also includes issuing 2D/3D instructions to the 2D/3D engine to carry out deinterlacing of lines of video data from interlaced fields. This may be done, for example, by another processing device, such as a host CPU, or any other suitable processing device.

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.
