Embodiment Construction

[0014] figure 1 It is a schematic diagram of the use of the color noise suppression system 500 of the present invention. exist figure 1 Among them, a YCbCr input device 100 receives a YCbCr input signal, wherein the Y, Cb and Cr signals range from 0 to 255. A deinterlacing device 200 converts an interlaced signal format into a progressive format. A scaling control device 300 enlarges or reduces the progressive scan frame output by the deinterlacing device 200 . A YCbCr to YUV conversion device 400 converts the image signal from the YCbCr format to the YUV format, wherein the Y signal ranges from 0 to 255, the U signal ranges from -128 to 127, and the V signal ranges from -128 to 127. The color noise suppression system 500 performs a chrominance suppression operation on the YUV image signal. A saturation and brightness adjustment device 600 performs saturation and brightness adjustment calculations on the YUV video signal with suppressed saturation. A YUV-to-RGB conversion...

Abstract

A suppressing system of color noise consists of converting unit for converting a YUV image signal to be a RGB image signal, saturation calculating unit for calculating saturation of RGB image signal and for converting saturation to be the first gain, maximum value calculation unit for calculating out maximum value of RGB image signal and for converting RGB maximum value to be the second gain, colourity suppressing unit for carrying out colourity suppression calculating on YUV image signal according to the first gain and the second gain.

Description

technical field [0001] The invention relates to a color processing system, in particular to a color noise suppression system. Background technique [0002] Due to the rapid development of multimedia technology, various multimedia devices (such as DVD players, digital cameras, and digital video cameras) have penetrated into every family. The main performance of these multimedia devices depends on the image quality. However, when framing natural scenes, due to the limitations of the instrument itself, some color noise will be generated in the image. For example, general CCD image sensing devices are prone to generate noise in the case of low light source or slow shutter speed. . In addition, in the process of image production or processing (such as MPEG compression), noises such as color spots (color blocks) will also be generated due to the loss or change of part of the image data. [0003] In order to solve the above-mentioned color noise phenomenon, two color noise elimi...
