Tone reproduction of High Dynamic Image

Abstract

High Dynamic Range Image (HDRI) is a type of images with wide luminosity levels in real scenes. It is very important to fuse the multiple photographs into a single HDRI. A method that constructs HDRI through recovering response curve of camera imaging system is proposed. The method can make effect of several important parameters to the synthesis results, and get a synthesis result for images missing the information of exposure time. As for the HDRI tone reproduction, an improved algorithm is presented in last part of the paper for processing HDRI and getting good performance
