1. A device, comprising: an input interface configured to access a high dynamic range (HDR) image; a processor configured to execute instructions to: generate a luminance ratio image based on luminance pixel values of the HDR image and a tone-mapped (TM) image, the TM image generated based on the HDR image; generate a re-mapped HDR image based on the luminance ratio image and the HDR image; generate residual values in color channels of a color space based on the re-mapped image and the TM image; and an output interface configured to output the TM image with HDR reconstruction data, the HDR reconstruction data being derived from the luminance ratio image and the residual values.
