Abstract
An image processing device and method for converting an input image having a first dynamic range into an output image having a second dynamic range higher than the first dynamic range are provided. The image processing device includes a mapping unit for transforming an input luminance value associated with a pixel of the input image into an output luminance value associated with the corresponding pixel in the output image. The mapping unit is configured to apply a continuous and increasing function mapping a first range of values into a second range of values, whereby the highest value in the first range of values is mapped by the continuous and increasing function into a supremum of the second range of values. The mapping unit is configured to adjust the supremum depending on a peak luminance.
