一种高帧频CMOS图像的非均匀性校正系统

针对高帧频CMOS相机图像的不均匀性，分析了产生图像不均匀性的原因，在此基础上设计了一种对图像的非均匀性校正系统。该系统采用了两点加一点的图像非均匀性校正改进算法，运用该算法对图像的非均匀性进行了处理；描述了该校正系统的实现模块包括软件模块与硬件模块。实验结果表明：该系统对处理图像的非均匀性有很好的效果，处理后的图像显得比较平滑，清晰度得到了很大的提高。

Non-uniformity correction system for high speed CMOS image

The reasons of the non-uniformity for the high speed CMOS camera image are discussed and described in this paper and thus a new non-uniformity correction approach for high speed CMOS image is also presented. This approach uses two points and one point of the image with improved non-uniformity correction algorithm, and is applied to process the image non-uniformity. In order to demonstrate the effectiveness of this non-uniformity correction approach, a serial of simulation experiments are also done. The experimental result indicates that the system has good effect on dealing with non-uniformity of the images. The image appears relatively smooth after processing and the definition has been greatly improved.
