基于颜色空间转换的高动态图像双屏显示方法

Dual Screen High Dynamic Range Display Method Based on Color Space Conversion

针对高动态范围图像映射后偏色问题及图像细节显示不足问题,提出了一种基于颜色空间转换与双屏结合的显示方法。首先将高动态图像转换到HSL空间,采用自适应对数算法进行亮度映射及相应的饱和度增强,再次转换到RGB空间并进行LCD-FED双屏分割显示。实验结果表明该方法不仅解决了偏色问题,而且在细节表现能力上也有了很大的提升,其失真度仅为3.7%。

For the problem of color cast in High Dynamic Range （HDR） image tone mapping and insufficient in image detail display, a dual screen high dynamic range display method based on color space conversion is presented. Firstly, high dynamic range image is converted into HSL space, then lightness is processed by adaptive logarithmic mapping algorithm, and saturation is enhanced. After that, processed image is converted into RGB space and displayed through LCD-FED dual screen. The experimental results show that this method not only solves the problem of color cast, but also greatly improves the ability of the detail performance： the distortion ratio （D） is only 3.7%.
