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