Abstract
Methods and systems for multi-step display mapping and metadata reconstruction for high dynamic range (HDR) images are described. In an encoder, given an HDR input image with input HDR metadata in a first dynamic range, an intermediate, base layer image in a second dynamic range is constructed based on the input image. In a decoder, using base-layer metadata, the input HDR metadata, and dynamic range characteristics of a target display, a processor generates reconstructed metadata which when used in combination with the base layer image allow a display mapping process to map the base layer image to the target display as if it was mapping directly the HDR image to the target display.
