Abstract
An image processing apparatus comprises a receiver () for receiving an image signal comprising an encoded image. Another receiver () receives a data signal from a display () where the data signal comprises a data field that comprises a display dynamic range indication of the display (). The display dynamic range indication comprises at least one luminance specification for the display. A dynamic range processor () is arranged to generate an output image by applying a dynamic range transform to the encoded image in response to the display dynamic range indication. An output () outputs an output image signal comprising the output image to the display. The transform may furthermore be performed in response to a target display reference indicative of a dynamic range of display for which the encoded image is encoded. 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.
