Zusammenfassung:This document describes methods and devices for encoding and decoding images and videos, including encoding high dynamic range images, both static images and video frames. In aspects, a high dynamic range image is acquired, a dynamic range value of the high dynamic range image and an image average luminance value of the high dynamic range image is calculated, the high dynamic range image is converted to a low dynamic range, and the low dynamic range is compressed. In aspects, a low dynamic range image is decoded back into a high dynamic range image.
