A method and device for reconstructing image data is provided that is representative of an original image data from a decoded image data and parameters obtained from a bitstream, the parameters having been processed from said original image data. The method provides a desaturating of a luma component, an inverse-mapping of desaturated luma component and a correction of chroma components. These operations are being modulated according to the value of a single modulation factor mod representative of a peak luminance of a presentation display on which the reconstructed image is intended to be displayed, a peak luminance of a particular range image and a peak luminance of the original image data or the mastering display used to grade the original image data.
A method for reconstructing image data (I3) representative of original image data (I1) from decoded image data (I2) and parameters obtained from a bitstream (101), said parameters having been processed from said original image data (I1), wherein the reconstructed image is adapted to a characteristic of a presentation display, the method comprising:
The method of 1 wherein the value of SDR_PL is 100 nits.
A device for reconstructing image data (I3) representative of original image data (I1) from decoded image data (I2) and parameters obtained from a bitstream, said parameters having been processed from said original image data (I1), wherein the reconstructed image is adapted to a characteristic of a presentation display, the device comprising a processor configured to:
