| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | To coding the high dynamic range (HDR) images, the quantization with the conversion based on the tone mapping is usually discussed. This method is suitable to view with normal (low) dynamic range display devices, but not suitable to the high fidelity transmission of HDR images. To realize high versatility and utility coding for the HDR images, we discuss the range coding with plural pixels combination. About the evaluation of coding for the HDR images, new type of SNR to use the independent pixel value for as a signal instead of the peak value is proposed. Tested pseudo 16 bit HDR images are made from 10 bit HDTV standard video with the conversion processing to evaluate many kind of images. As the results of experiments, simple range coding is poor than gamma conversion, however, the proposed coding, especially 4 pixel combine method gives best performance. | |
