摘　　要：目的研究高动态影像(HDR)在低动态范围显示设备上的高保真显示问题。方法论文采用图像色貌模型(iCAM)设计了高动态影像的再现技术框架,并使用C++语言搭建了软件实现系统,通过计算机测试平台对输入图片进行了实证,算法重点是处理影像的明视度。结果结果表明,显示图像的动态范围拓展10%以上,色差小于1.6ΔE*ab,图像细节得到加强,基本达到高动态影像高保真显示的要求。结论因此,可利用iCAM框架来实现高动态影像在常规显示设备上高保真显示的问题,具有重要的理论意义与技术价值。It researched the high-fidelity display problem of high dynamic images(HDR)in the low dynamic range display equipment.It used the image color appearance model(iCAM)to design the reproduction technical framework of high dynamic images and used the C++language to build a software reality system.An empirical input image was actually tested by the computer platform and the image processing algorithm focused on photopic degree.The results showed the dynamic range expansion of display image was more than 10%,the color aberra-tion was less than 1.6 AE*ab,the image details were to be strengthened,basically met the high-fidelity display requirement of high dynamic image.Thus,it can use iCAM framework to achieve the high-fidelity display of high dynamic images in common display devices and had an important theoretical and technical value.
