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.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"4","bibliographic_titles":[{"bibliographic_title":"研究報告オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2015-07-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2015-AVM-89"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":144124,"links":{}}
