摘要： Image ringing noise is reduced by calculating a line spread function value of each pixel's luminance in an input image, dividing the input image into a plurality of blocks, and calculating an average value and a maximum value of the line spread function values for all pixels in each block. Based on the average value and the maximum value of the line spread function values of each block, whether a block is an interfered flat block or a non-interfered block is determined and the pixels in the interfered flat block are set as noisy pixels. Whether each pixel in the non-interfered block is an edge pixel or a non-edge pixel is determined and the non-edge pixels in the non-interfered block are set as noisy pixels. The noisy pixels thus set are smoothed, and the smoothed pixels are combined with the edge pixels for output as an output image.

摘要： Block noises at block boundaries are removed, but when a contour line in the original image matches a block boundary, the degree of block noise removal is adjusted and image quality is improved. An adaptive filter has a step of calculating the weight of pixels near the block boundary by a high-pass filter, and a step of determining an adjusted value for the pixels near the block boundary based on the weight. The pixel values near the block boundary are adjusted and block noises are removed. A low-pass filter is applied to pixels near the block boundary to determine a filtered value. The adjusted values of the pixels near the block boundary are determined by obtaining a weighted sum of the original pixel value and the filtered value. Because the high-pass filter recognizes the definition of pixels near the block boundary, and the low-pass filter reduces the difference between pixels near the block boundary, the adaptive filter outputs the adjusted value, and this value removes block noise while retaining image definition.

摘要： A method for adjusting the PCI Express lane ordering is disclosed, comprising the following steps. The first packet associated with a first PCI Express lane ordering is sent to the peripheral device. The peripheral device replies the second packet associated with the second PCI Express lane ordering. Whether the PCI Express lane ordering is correct is determined in response to said second packet. The first PCI Express lane ordering is adjusted while the first PCI Express lane ordering does not match the second PCI Express lane ordering. Preferably, the adjusted PCI Express lane order matches the normal order or the reverse order. Then, reset and reinitialize the peripheral device. The resetting step can be accomplished by sending reset packets, or changing the common mode voltage level in order to reset the bridge chipset of the PC.
