摘要： A super dithering method of color video quantization maintains the perceived video quality on a display with less bit depth of color than the input video. Super dithering relies on both the spatial and temporal properties of human visual system, wherein spatial dithering is applied to account for human eye's low pass spatial property, while temporal dithering is applied to achieve the quantization level of the spatial dithering.

摘要： A method of reducing noise in a sequence of digital video frames is performed by motion estimation between a current noisy frame and a previous noise-reduced frame, to generate motion vectors indicating relative motion between the pixels in the current noisy frame and the corresponding pixels in the previous noise-reduced frame; and removing noise from the current noisy frame by computing the weighted average of pixels in the current noise frame and the corresponding pixels in the previous noise-reduced frame based on the motion vectors, to generate a noise-reduced output frame.

摘要： A display system that displays a mixture of 2D and 3D video content is provided. A switching mechanism in the display system turns the 2D/3D mode of different portions of the screen on and off independently and automatically. Any type (2D, 3D, mixed) of video content can be displayed on any part of the screen simultaneously. The switching between different modes (2D, 3D, mixed) is performed automatically according to input control signals received from an internal device, or determined by a 2D/3D content detector in a computer, set-top-box, and/or cable/satellite tuner/receiver.

摘要： A noise estimation system that estimates noises in a sequence of video frames, uses a an image structure remover and a noise variance calculator. The image structure remover computes the difference over a local window in two consecutive frames. The noise variance calculator estimates the noise variance (standard deviation) from the distribution of the local difference. If there is no motion or small motion between two consecutive frames, the image structure can be removed by calculating the local difference, whereby very robust estimation is obtained.

摘要： The present invention relates to a method for adjusting the saturation levels of the pixels of a time varying image being represented by RGB color sample vectors {right arrow over (C)} in an RGB color system. The method does not require the RGB color sample vectors {right arrow over (C)} to be converted into YUV samples in order to subsequently perform saturation adjustment. The method includes steps of: decomposing an RGB color sample vector {right arrow over (C)} into a white vector {right arrow over (w)} and a color tone vector {right arrow over (C)}T; obtaining a saturation adjusted color tone vector {right arrow over (CTo)} by multiplying the color tone vector {right arrow over (C)}T by a saturation adjustment parameter; obtaining a saturation adjusted RGB color sample vector {right arrow over (C)}o by adding the white vector {right arrow over (w)} and the saturation adjusted color tone vector {right arrow over (CTo)}; and using the saturation adjusted RGB color sample vector {right arrow over (C)}o to represent a color pixel of an output image.

摘要： A system and method that detect the location as well as the luminance transition range of slant image edge in a digital image. The variance value for the pixels inside a window in the image is calculated. Based on the variance value, a current pixel can be classified as being in an edge region or in a non-edge region. If the current pixel is in a non-edge region, no further checking is needed, otherwise binary pattern data is generated from the pixels inside the window. Then it is determined whether the current pixel is a center pixel in a luminance transition range of a slant edge based on the binary pattern data at the current pixel location and its neighboring binary pattern data. It is determined if the current pixel is the center pixel in a luminance transition range of a e.g. ±45° direction edge. If it is, then no further processing is needed at the current pixel location and the luminance transition range is considered as 3 pixels wide. Otherwise, based on the neighboring binary pattern data, another checking process is performed to determine whether the current pixel is a center pixel in a luminance transition range other than a ±45° slant edge. If the current pixel is considered as a center pixel in a luminance transition range other than a ±45° slant edge, then the length of the luminance transition range of the slant edge is determined by checking more binary pattern data inside the window.

摘要： A motion decision value provides a dependable estimate whether motion occurs in a given region of a video image in an interlaced video sequence. The motion detection is particularly applicable in the conversion from interlaced video to progressive video. An input first is fed to an absolute value former which computes a frame difference signal from a difference between the first field and the second field in one frame. A point-wise motion detection in the frame difference signal is then followed by a region-wise motion detection that combines the point-wise motion detection signal with an adjacent point-wise motion detection signal delayed by one field. The motion decision value is then computed from the region-wise motion detection signal and output for further processing in the video signal processing system, such as for choosing whether the spatially interpolated video signal value or the temporally interpolated video signal value should be used for the output.
