Abstract: A method and system for producing a single view video signal based on a multiview video coding (MVC) signal stream. A MVC signal stream representing multiple spatially related views of a scene, including a base view and at least one dependent view, is decoded to provide multiple decoded video signals representing the spatially related views, with respective portions of the MVC signal stream representing one of multiple temporally adjacent video frames, and the MVC signal stream representing multiple sequences of spatially adjacent video frames. The decoded video signals are processed to provide a processed video signal representing one of the spatially related views using image information from more than one of the decoded video signals. As a result, more image data is used during processing, thereby improving the spatial and temporal image quality.

Abstract: A method and system are provided for navigating and selecting objects within a 3D video image by computing a depth coordinate based upon two-dimensional (2D) image information from left and right views of such objects. In accordance with preferred embodiments, commonly available computer navigation devices and input devices can be used to achieve such navigation and object selection.

Abstract: An edge enhancer for enhancing edges within a video image, forms an edge enhancement signal of odd harmonics of a sinusoid representative of the edge content in an incoming signal. The edge enhancement signal may be added to a version of the incoming signal, thereby sharpening the edge in the incoming signal. This allows edges to be enhanced, increasing the image's rise-time without adding overshoot. Sharper edges are thus produced in much the same way as a square wave may be formed of odd harmonics of a sinusoid.

Abstract: A video graphics chip includes a graphics module configured to process incoming video information in accordance with different modes to produce a video output signal and to transmit the video output signal toward a display screen for rendering of video corresponding to the video information, and a display mode module coupled to the graphics module configured to analyze the incoming video information to determine a type of video associated with the incoming video information and to send a video mode indication of a preferred video processing mode for the incoming video information to the graphics module, where the graphics module is configured to process the incoming video information in accordance with a selected mode from the plurality of different modes based on the video mode indication received from the display module.

Abstract: 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.

Abstract: An image analyser analyses regions of an image. An image scaler may then scale the image adaptively, in dependence on the nature of region of the image being scaled. In one embodiment, adjacent pixels are analysed to determine their frequency content. This frequency analysis provides an indication of whether the pixels likely contain hard edges, discontinuities or variations typical of computer generated graphics. As a result of the analysis, the type of scaling suited for scaling the image portion containing the pixels may be assessed. Adjacent pixels having high frequency components may be scaled by a scaling circuit that introduces limited ringing. Adjacent pixels having lower frequency components may be scaled using a higher-order multi-tap scaler. Resulting scaled pixels may be formed as a blended combination of the two different scaling techniques.

Abstract: A wireless drawing command transmitting unit includes a wireless transmitter operative to transmit drawing commands associated with a master image renderer. A wireless drawing command receiving unit includes a wireless receiver operative to receive the transmitted drawing commands and generates an image for a display device using the drawing commands transmitted wirelessly. In addition, the wireless drawing command receiving unit transmits drawing command throttle data back to the wireless drawing command transmitting unit to throttle transmission of drawing commands that are sent by the drawing command transmitting unit. A method for providing wireless display of images is also disclosed.

Abstract: 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.

Abstract: A method and apparatus for enhanced image display that substantially eliminates video image fragments include processing that begins by monitoring color data of an image to be displayed. The processing then continues by determining whether at least a portion of the image includes color data that matches a chroma key color. When at least a portion of the image includes color data that matches the chroma key color, the processing continues by adjusting the color of at least a portion of the image to produce adjusted color data such that the adjusted color data does not match the chroma key color.
