In this article, tone mapping operations and image compression schemes are considered for HDR images, under the assumption that LDR displays with several bit-depths are used. In the proposed framework, a tone mapping operation is applied to a HDR image to generate a LDR image with a specified bit-depth, and the LDR image is then compressed. The decoded LDR image can be mapped to other LDR images with several arbitrary bit-depths appropriate for displays, by using a simple linear tone mapping operation. In the framework, the HDR image is not requested to be stored, and only the LDR image with a specified bit-depth is stored. Experiment results show that the compression of LDR images with higher bit-depth provide better quality images, without increasing any file size, than the use of lower ones. |
