摘　　要：针对Android移动终端和低照度图像的特点,提出了一种改进的直方图均衡化的图像增强算法.首先将采集到的RGB图像转换到HSV彩色空间,对V通道的像素进行区分,对需要处理的像素进行直方图均衡化,之后重新转回RGB空间,对整幅图像进行Gamma校正.最后在Android平台上进行试验.结果表明,该方法能够增强低照度图像,也能够满足实时性要求.In view of the features of Android mobile devices and low - light images, an improved histogram equalization image enhancement algorithms was presented. Firstly, the images were converted in RGB color space that had been collected to HSV color space, and the pixel of V channel were distinguished and the needed pixel in histogram equalization was processed. Secondly, the images were backed to RGB space again and were processed in Gamma correction for the whole image. Finally, it was tested on the Android platform. The results showed that this method can enhance low - light images as well as meet real - time requirements.
