    摘要: An apparatus generates an image coding signal comprising for each image a first pixelized picture and a second pixelized picture having a luminance component and a chroma component. The apparatus comprises a first picture processor (203, 211) which includes image encoding data for an encoded first image in the first pixelized picture. A second picture processor (205, 207, 209, 211) includes dynamic range extension data in the second pixelized picture. The dynamic range extension data may be dynamic range extension data included in a chroma component of the second pixelized picture for generating an increased dynamic range image on the basis of the encoded first image. The compensation data may e.g. be compensation data for correcting another LDR-to-HDR transform, e.g. a prefixed global gamma transformation. The dynamic range extension data may be included in a luminance component and comprise data representing a dynamic range extension transform for generating an increased dynamic range image from the encoded first image.

    摘要: A display apparatus for presenting an image comprises an image receiver (101) for receiving an image to be displayed. An image analyzer (103) performs a local image profile analysis on at least a first region of the image to determine a pixel value spatial variation characteristic. The image analyzer (103) is coupled to a scaling processor (105) which scales at least a second region of the image in response to the pixel value spatial variation characteristic. The scaling processor (105) is coupled to a presentation controller (107) which presents the scaled image. The scaling may specifically be adjusted dependent on a sharpness or spatial frequency characteristics of the image. The invention may allow an improved adaptation of the presentation of one or more images to the specific characteristics of the image(s).

    摘要: A device and method for rendering content that includes analyzing previous and/or subsequent temporal portions of a content signal to determine elements that are positionally related to elements of a current portion of the content signal. The current portion of the content signal is rendered on a primary rendering device, such as a television, while the elements that are positionally related to elements of a current portion of the content signal are concurrently rendered on a secondary rendering device. In one embodiment, the elements that are rendered on the secondary rendering device may be rendered at a lower resolution and/or lower frame rate than the rendered current portion of the content signal. In one embodiment, at least one of previous and subsequent temporal portions of a content signal may be analyzed at a lower resolution than the content signal.
