Abstract
A method comprising: obtaining (140) reconstructed SDR data and metadata representative of a first inverse tone mapping function allowing transforming the reconstructed SDR data into HDR data with a dynamic range having a first peak luminance; deriving (141), using the metadata, a second tone mapping function allowing transforming the SDR data into HDR data with a dynamic range having a second peak luminance lower than the first peak luminance; reconstructing (143) the HDR data using the second tone mapping function, the HDR data being intended to be displayed on a display device; wherein: the second peak luminance is lower than a third peak luminance supported by the display device.

A method comprising:
- obtaining reconstructed SDR data and metadata representative of a first inverse tone mapping function allowing transforming the reconstructed SDR data into HDR data with a dynamic range having a first peak luminance;
- deriving, using the metadata, a second tone mapping function allowing transforming the SDR data into HDR data with a dynamic range having a second peak luminance lower than the first peak luminance, the second peak luminance being derived from an information representative of the second peak luminance, the information representative of the second peak luminance being an energy consumption reduction target or an energy consumption profile selected in a plurality of energy consumption profiles;
- and,
- reconstructing the HDR data using the second tone mapping function, the HDR data being intended to be displayed on a display device;
- wherein:
- the second peak luminance is lower than a third peak luminance, the third peak luminance being the maximum peak luminance supported by the display device.
