Abstract: A method of generating motion vectors for image data includes identifying boundaries of at least one object in original frames of image data, performing object motion analysis based upon the boundaries, performing pixel-level motion layer generation, using the object motion analysis and the pixel-level motion layers to generate motion for blocks in the image data, and producing block level motion information and layer information for the original frames of image data.

Abstract: A method of determining an output frame rate includes receiving an input sequence of frames of image data at an input frame rate, performing motion vector calculations on the frames of image data to produce motion vectors and motion statistics, determining a motion level in the frames using the motion statistics, and interpolating frames of image data at the output frame rate, wherein the output frame rate is based upon the motion level.

Abstract: An on-screen display (OSD) processing system can include video data fetch modules to receive video data from a video source, edge detection modules to detect an edge of a region within a scene represented by the video data, edge processing modules to process results from the edge detection modules, and an OSD confidence level adjustment module to adjust an OSD confidence level corresponding to the region within the scene.

Abstract: To denoise video data, a temporal IIR filter is applied to video data. The temporally filtered frame is used as a guide to spatially filter the video data without introducing temporal artifacts. The spatially filtered frame can then be temporally filtered again using a temporal IIR filter. The results of the second temporal filtering can then be used as a guide to eliminate noise that the spatial filter did not eliminate.

Abstract: A method to produce a frame of video data includes receiving original frame true motion information, original frame object boundary information, and original frame layer information for at least two original frames of video data, and generating interpolation phase block-level motion and interpolation phase pixel-level layer information from the original frame block-level true motion information, original frame pixel-level object boundary information, and original frame pixel-level layer information for the original frame.

Abstract: A method of performing motion compensation includes identifying a set of candidate motion vectors for a block in an intermediate frame from a set of motion vectors from a previous and current frames, performing block-level analysis for each candidate motion vector, selecting an interpolation motion vector, and using the interpolation motion vector to interpolate the intermediate frame between the previous and current frames, wherein the number of intermediate frames depends upon a conversion to a faster frame rate. A method of determining background and foreground motion vectors for a block in an interpolated frame includes comparing a first motion vector that points to a previous frame to a second motion vector that points to a next frame to produce a difference, and designating one of the first and second motion vectors as a background motion vector and the other as a foreground motion vector depending upon the difference.

Abstract: A method of reducing artifacts in video image data includes determining pixels in a block of image data that are mosquito pixels, estimating a level of mosquito noise in the block, and filtering out the mosquito noise to produce noise-filtered data.

Abstract: An apparatus has a motion vector estimation module to perform motion vector estimation on a current frame and on a previous frame of image data to produce a current phase and a previous phase, a motion vector generation module to generate motion vector fields for the current and previous phases, and a motion vector interpolation module to find interpolated motion vectors for an interpolated phase that have minimal differences between motion vectors in the current and previous motion vector fields and to product interpolated motion vectors.

Abstract: A method of performing motion compensation includes dividing a current frame of video data into blocks, and clustering the blocks based on motion vectors.

Abstract: We describe a device and an associated method that includes an EHT signal processing module to generate a compensated gain signal responsive to a first EHT signal. A field fly-back processing module generates a first correcting signal responsive to a first VFB signal. A horizontal scanning correction module generates a predistortion signal responsive to the compensated gain signal. A first digital to analog conversion module converts the predistortion signal into a corresponding analog predistortion signal. A field scanning correction module generates a correcting wave responsive to the compensated gain signal and the first correcting signal. A pulse width modulated module generates a modulated correcting wave by pulse width modulating the correcting wave. A power amplification module generates an amplified modulated correcting wave by amplifying the modulated correcting wave. And a cathode ray tube displays an image responsive to the analog predistortion signal and the amplified modulated correcting wave.
