Abstract:
An image processing method is described. The method includes obtaining low dynamic range expansion exponents E LDR (p), obtaining target expansion exponents E T (p) as a weighted sum of the high dynamic range expansion exponents E HDR (p) and of the low dynamic range expansion exponents E LDR (p), applying obtained target expansion exponent E T (p) to low dynamic range luminance values Y LDR  of a low dynamic range version of the image, resulting in target luminance values Y T , and building a tone-adapted version of said image based on said target luminance values Y T .

Claim (Index 2):
An image processing device for tone adapting an image to a target peak luminance L T  of a target display device from a low dynamic range version of this image adapted to be displayed on a display device having a low peak luminance L LDR , and from high dynamic range expansion exponents E HDR (p) to be apply to low dynamic range luminance values Y LDR  or to low pass filtered luminance values of said low dynamic range version of said image to get expanded luminance values Y HDR  of a high dynamic range version of said image adapted to be displayed on a display device having a high peak luminance L HDR , said device comprising at least one processor configured for:\n obtaining low dynamic range expansion exponents E LDR (p) such that, when applied to low dynamic range luminance values Y LDR  or to low pass filtered luminance values of said low dynamic range version of said image, low dynamic range luminance values Y LDR  are linearly scaled within a high dynamic range [0, L HDR ], obtaining target expansion exponents E T (p) as a weighted sum of the high dynamic range expansion exponents E HDR (p) and of the obtained low dynamic range expansion exponents E LDR (p), with a weight 0\u2264\u03b1 in \u22641 of the high dynamic range expansion exponent E HDR (p) and with a weight of the low dynamic range expansion exponent E LDR (p) equal to (1\u2212\u03b1 in ), wherein the weight \u03b1 in  of the high dynamic range expansion exponent E HDR (p) is proportional to a difference between the target peak luminance L T  of the target display device and the low peak luminance L LDR , this difference being scaled by another difference between the high peak luminance L HDR  and the low peak luminance L LDR , applying obtained target expansion exponent E T (p) to low dynamic range luminance values Y LDR  or to low pass filtered luminance values of said low dynamic range version of said image, resulting in target luminance values Y T , building a tone-adapted version of said image based on said target luminance values Y T .
