Claim 0:
1. An image processing apparatus, comprising:
a receiver, wherein the receiver is configured to receive an image signal, wherein the image signal comprises at least a first encoded image and a first target display reference, wherein the first target display reference is indicative of a dynamic range of a first target display device for which the first encoded image is encoded, wherein the image signal comprises pixel lumas for one or more pixels of the first encoded image, wherein the first target display reference comprises an indication of an Electro Optical Transfer Function for the first target display device, wherein the Electro Optical Transfer Function relates luma codes to luminance values, and wherein a highest luminance value corresponds to a highest luma code, and wherein the highest luminance value is above 2000 nits:
a dynamic range processor, wherein the dynamic range processor is arranged to generate an output image by applying a dynamic range transform function to the pixel lumas of the first encoded image, wherein a shape of the dynamic range transform function is dependent on the indication of the Electro Optical Transfer Function for the first target display device; and
an output, wherein the output is configured to output an output image signal comprising the output image.
