Abstract  Abstract

PROBLEM TO BE SOLVED: To generate a high dynamic range image from a low dynamic range image or a low dynamic range image from a high dynamic range image.

SOLUTION: 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 to a suitable display. The dynamic range transform may further be performed in response to a display dynamic range indication received from a display.
