| 摘 要： | 介绍了基于图像处理方法的自适应对比度增强系统的组成、工作原理、硬件电路设计与软件设计.针对监察相机工作环境照度变化范围大的特点,提出一种改进的灰度直方图均衡化方法.应用此方法所研制的系统,能够自适应于多种光照条件下获得的低对比度图像,自动进行对比度调整,改善监察相机输出视频图像的质量.对于清晰图像,经调整后图像质量至少无明显降低.

| Abstract: | The constitution,operating principle,hardware and software of adaptive contrast enhancement system based on image processing method is presented.In view of the feature that reconnaissance camera working in different illumination conditions,modified histogram equalization method is introduced.Developed system by this method,can be adaptive to low-contrast image obtained in multiplicate illumination conditions.It can adjust contrast automatically and ameliorate quality of video image from reconnaissance camera.Quality of adjusted image is not debased obviously at least for clear images. |
