Abstract: High Dynamic Range (HDR) images are very important method and have been widely used in many areas such as remote sensing,virtual reality,medical images,and cross-media publishing.But the restriction of treatment capability of display and output make it necessary to compress original HDR image before which are outputted in the conventional display and output device.So how to ensure that the best performance of HDR image reproduction is one of the key technologies of HDR image displays.This paper analyzes the mechanism of six high dynamic range image tone compression algorithms which are representative at present.The effect of the HDR image compression algorithms are analyzed and implemented.Then the 6 HDR image compression algorithms are compared by compression test through the subjective and objective evaluation methods.Research results show: compared to other algorithms,image color appearance model based on iCA M06 compression algorithm in HDR image tone compression and reproduce has obvious advantages.

Key words: high dynamic range image, tone compression, iCA M06
