An iterative algorithm for image rendering on High Dynamic Range displays
Recent advancements in display technologies created possibility for production of High Dynamic Range (HDR) displays. These HDR displays are capable of generating high luminance values up to 4000-6000 nits where conventional Low Dynamic Range (LDR) displays can generate luminance values between 100-500 nits. This increase in luminance values have different implications on human visual perception and the quality of the observed material. This study presents an iterative algorithm for image rendering on dual modulation HDR displays in order to both create and estimate accurate luminance values. In order to understand how it works, the characteristics properties of the SIM2 HDR47 display has been analyzed in detail. The details of the developed iterative algorithm have been explained, and results have been presented. Several measurements have been made to validate the proposed rendering algorithm. The results show that the proposed algorithm estimates the emitted luminance accurately and gives more accurate results when compared to built-in rendering algorithm of SIM2 HDR47 display.
