一种基于自适应对比度调整的电视画质增强技术

A Video Quality Enhancement Method Based on Adaptive Contrast Adjustment

提出一种新的自适应对比度增强方法,该方法基于分析输入图像的信息,调整特定需要区域的亮度值,以达到改善电视图像对比度效果。在对比度改善和保持图像色饱和度方面效果明显,而且计算量小,处理速度快,完全适用于计算资源有限、实时性要求较高的电视播放系统。

This paper proposes a new method of improving the television＇s contrastive effect which adaptively adjusts the brightness on the basis of analyzing the information of input images. This method can enhance the contrast and improve the maintenance of the image＇s color saturation, and also it needs few calculated amount and provide high-speed processing. This method is applicable to the TV system with limited compute resource and real time operation.
