| Research Abstract |
In this study, the limit of the image reproduction using an LDR device has been solved by developing an effective tone mapping technique from HDR to LDR. At that time, luminance adaptation and chromatic adaptation in human visual system were considered. Then, an appropriate criterion for evaluating reproduced images by considering the relationship between subjective evaluations and colorimetric values. Furthermore, a low quantization problem at low intensity level has been tackled by applying digital half-toning techniques to a display device.
