Estimating the term…
An image processing apparatus comprises a receiver (201) for receiving an image signal which comprises at least an encoded image and a target display reference. The target display reference is indicative of a dynamic range of a target display for which the encoded image is encoded. A dynamic range processor (203) generates an output image by applying a dynamic range transform to the encoded image in response to the target display reference. An output (205) then outputs an output image signal comprising the output image, e.g. to a suitable display. The dynamic range transform may furthermore be performed in response to a display dynamic range indication received from a display. The invention may be used to generate an improved High Dynamic Range (HDR) image from e.g. a Low Dynamic Range (LDR) image, or vice versa.

The image signal encoding apparatus of 20 wherein the generator is further arranged to generate the image signal to comprise a data field including dynamic range transform control data;
An image processing method comprising:
A method of transmitting an image signal, the method comprising:
A storage medium having an image signal comprising at least a first encoded image comprising pixels which should be rendered with a luminance of at least 1000 nits and a first target display reference for the encoded image co-encoded in the image signal, the first target display reference being indicative of a dynamic range of a first target display for which the first encoded image is encoded, and the target display reference comprising a white point luminance of the target display.
