Abstract:
A method for decoding an image enables to preserve artistic intent at the final rendering stage by adjusting the image to luminance characteristics of the content and of the presentation display that will display the image. Values representative of luminance of both the image and the display device are obtained. Parameters of a display adaptation function are adjusted according to these values and the adjusted display adaptation function is used to decode the image. In at least one embodiment, the adjusted display adaptation function relates to a tone mapping function. Corresponding apparatus implementing the method is also described.
