Abstract:
Techniques are provided to encode and decode image data comprising a tone mapped (TM) image with HDR reconstruction data in the form of luminance ratios and color residual values. In an example embodiment, luminance ratio values and residual values in color channels of a color space are generated on an individual pixel basis based on a high dynamic range (HDR) image and a derivative tone-mapped (TM) image that comprises one or more color alterations that would not be recoverable from the TM image with a luminance ratio image. The TM image with HDR reconstruction data derived from the luminance ratio values and the color-channel residual values may be outputted in an image file to a downstream device, for example, for decoding, rendering, and/or storing. The image file may be decoded to generate a restored HDR image free of the color alterations.

Claim (Index 11):
The system of  claim 8 , wherein given a quantized residual chroma pixel value U, a corresponding intermediate residual chroma pixel value Cb is determined as Cb = U \ue8a0 ( Cb ma \ue89e \ue89e x - Cb m \ue89e \ue89e i \ue89e \ue89e n 255 ) + Cb m \ue89e \ue89e i \ue89e \ue89e n , wherein Cb min  denotes a minimum residual chroma pixel value chroma de-quantization parameter and Cb max  denotes a maximum residual chroma pixel value chroma de-quantization parameter.
