PROCESSING HIGH DYNAMIC RANGE IMAGES

摘要

Various implementations address high dynamic range ("HDR") images. In one particular implementation, a low dynamic range ("LDR") image is generated from an HDR image, and information is generated allowing the HDR image to be reconstructed from the LDR image. The LDR image and the information are encoded. In another implementation, a signal or signal structure includes an LDR section including the encoded LDR image, and an information section including the encoded information. In another implementation, the encoded LDR image and the encoded information are both decoded. The HDR image is then reconstructed based on the decoded LDR image and the decoded information.
