    摘要: A processing chain for a digital image signal applies a dither pattern, having a first spectrum, to the image signal at a point in the processing chain. A further noise pattern is applied to the image signal during the processing chain. The noise pattern has a second spectrum which is configured such that the combination of the first spectrum and second spectrum results in a more continuous spectrum. Another aspect describes a noise pattern which can be used as an offset dither pattern for digital images, especially before colour bit depth reduction. The noise pattern has an array of values which are linearly distributed across a range, with each value in the range occurring an equal number of times.

    摘要: Circuits, systems, and methods for processing outlier pixels include a spatial filter and a temporal filter. The spatial filter is configured to compute a pixel difference for each pixel as a function of a pixel value of the pixel and pixel values of nearby pixels within each frame. The spatial filter is configured to dynamically add the pixel to a candidate list when the pixel difference exceeds a threshold value. The temporal filter dynamically removes a pixel from the candidate list when there is a divergence of a pixel value of the pixel in successive frames. The temporal filter determines a pixel in the candidate list is an outlier pixel when there is no such divergence in the successive frames.

    摘要: An image sharpness device and a method for the same are disclosed. The image sharpness device includes a DC removal unit, at least one filter, at least one noise estimation unit, at least one soft threshold processing unit, and a summing unit. The DC removal unit receives a luminance signal of a field of a frame and removes a DC component of the luminance signal. The filter passes a component of an output of the DC removal unit within a predetermined frequency band. The noise estimation unit estimates a noise value of the field. The soft threshold processing unit forms a sharpness signal according to the noise value. The summing unit sums the luminance signal and the sharpness signal to output a resultant luminance signal. The present invention is capable of avoiding the problem that a noise in the luminance signal is enhanced.

    摘要: An integrated system for adaptive equalization and jitter reduction of a video signal that includes an adaptive equalizer and a jitter cleaner located on one integrated circuit within a single package. An adaptive equalizer applies frequency specific signal modification to the received signal. A bit rate detector determines a bit rate of the video signal or the equalized signal. The jitter cleaner couples to the adaptive equalizer output and processes the equalized signal to reduce jitter in the equalized signal. A multiplexer receives the equalized signal and the jitter cleaner output and, responsive to a control signal, outputs either the equalized signal or the jitter cleaner output signal. A status monitor may optionally be included to compare the detected bit rate to a bit rate threshold, and a responsive to the comparing activate or deactivate the jitter cleaner and output either the equalized signal or jitter cleaner output.
