    摘要： A video processing system may be operable to utilize multi-band sharpening to process luma signals for image signals. The luma signal may be decomposed into a plurality of frequency band components, wherein each component may be processed separately using different sharpening gains and/or offsets. The multi-band processed components may be combined to generate sharpened output luma signals. The multi-band sharpening may be performed utilizing peaking processing, and the input luma signal and/or LTI sharpened luma signals may be combined with the multi-band peaking sharpened signals to generate the sharpened output luma signals. Corresponding chroma signals may also be adjusted to generate sharpened output chroma signals. Luma and/or chroma sharpening operations may be further adjusted based on coring, clipping avoidance, luma statistics, color region detections, and/or curve control parameters. Sharpened output image signals may be generated based on the sharpened output luma signals and the sharpened output chroma signals.

    摘要： A video processing system may be operable to utilize one-dimensional (1-D) piecewise linear (PWL) functions to adjust chroma and/or luma parameters corresponding to pixels that are determined to fall within one or more N-dimensional color adjustment regions in spatial representation of pixels' chroma and luma information. The chroma and/or luma parameters comprise Y, Cb, Cr, saturation and/or hue parameters in systems using Y′CbCr color coding. The 1-D PWL functions are operable to generate adjustment data corresponding to one of chroma and/or luma parameters, wherein the adjustment data comprise offset or gain data. The 1-D PWL functions are reprogrammable. The 1-D PWL functions may enable smooth transitions in boundary areas of at least some of the N-dimensional color adjustment regions. Determination of whether pixels fall within the color adjustment regions is based on a plurality of boundary points and/or criteria. Adjustment data corresponding to overlapped regions are aggregated.

    摘要： The methods provided use external fields such as light and electricity as a means of directing the crystallization of concentrated colloidal systems. Not only can nucleation be directed, crystal melting can be carefully controlled and light-induced crystal diffraction used as a means of directing light propagation. A number of factors play a significant role on the crystallization rate and location, including the intensity of the light field, the magnitude of the electric field, the colloid concentration, the colloid size, and the colloid composition. In varying these parameters, kinetics in these processes are extremely fast when compared to traditional colloidal crystallization approaches.

    摘要： A device has a processor for processing a vertex processing stage, a sub-screen dividing stage and a pixel rendering stage of a three-dimensional (3D) graphics pipeline. The processor includes processing threads which balance the work load of the 3D graphics pipeline by prioritizing processing for the pixel rendering stage over other stages. Each processing thread, operating in parallel and independently, checks a level of tasks in a Task list of sub-screen tasks. If the level is below a threshold value, empty or the sub-screen tasks are all locked, the processing thread loops to the vertex processing stage. Otherwise, the processing thread processes a sub-screen task during the pixel rendering stage.
