摘要:
The method of analyzing a difference of at least two gradings of an image on the basis of: obtaining a first graded picture (LDR) with a first luminance dynamic range; obtaining data encoding a grading of a second graded picture (HDR) with a second luminance dynamic range, different from the first luminance dynamic range; determining a grading difference data structure (DATGRAD) on the basis of at least the data encoding the grading of the second graded picture (HDR), allows more intelligently adaptive encoding of the imaged scenes, and consequently also better use of those pictures, such as higher quality rendering under various rendering scenarios.

摘要:
A display apparatus comprises a display on which first video content of a video signal is presented. In addition, second video content is simultaneously presented e.g. superimposed on the first video content. A presentation processor (209) determines a first characteristic for the presentation of the first video content and a characteristics processor (211) determines a presentation characteristic for the second video content from the first characteristic. A transmitter (213) transmits the presentation characteristic to an external source of the second video content. A single device (401) may generate the video signal comprising both the first and second video content. In this case a characteristic of the overlaying is adjusted in response to the presentation characteristic. The invention may provide an advantageous adaptation of secondary (overlay) information to the current characteristics experienced when presenting primary video content.

The invention relates to a lighting device and a method of manufacturing such a lighting device. The lighting device (1) comprises a first light emitting element (101) being optically coupled to a light guide (110) having an out-coupling surface (111) for illumination via the light guide. Further, the lighting device comprises a second light emitting element (102) dedicated for direct illumination from the lighting device. The invention is advantageous in that the lighting device provides both a decorative look and a functional illumination, and is still energy-efficient since the light emitted from the second light emitting element is directly emitted from the light emitting element without unnecessary energy-loss.

This invention relates to an ambience lighting system for a display device for emitting an ambience light onto a wall behind the display device. Light sources are placed at the rear side of the display device along with a reflector, where the internal arrangement of the light sources and the reflector is such that when the display device is placed in proximity to the wall the light emitted by the at least one light source becomes reflected by the reflector towards the wall such that the reflected light at least partly peripherally surrounds the viewing area of the display device.

A display system providing an enhanced viewing experience is provided. The system enables having backlighting colors fast adapted to the screen content while at the same time also having a relaxed viewing experience because the luminance slowly changes over time. A method and a computer-readable medium are also provided.
摘要:
A method for controlling an ambient lighting element including receiving a content signal, analyzing the content signal to determine a motion vector of an object (120A) depicted in the content signal, presenting the content signal on a display device, and adjusting an ambient lighting effect provided by the ambient lighting element as determined by the motion vector The presented content signal maybe portioned into macro-blocks (110A) and sub-blocks (230). A motion vector of each sub-block (230) may be resolved into components that are parallel and perpendicular to an outside edge of the display device. An average color of each sub-block (230) depicted within a macro-block (110A) in proximity to an outside edge of the display device may be weighted by the motion vector of the corresponding sub-block (230) for determining an average color of the macro-block (110A). The average color of the macro-block (110A) may be used to adjust the ambient lighting element.
摘要:
The invention relates to an ambience lighting system, typically for use in conjunction with a display device. The ambience lighting system may be of the type AmbiLight. The ambience lighting system comprises one or more light sources associated to subregions of the display screen; a content characterizer for determining content characteristics of image data of the sub-regions; and a controller to control the color of the emitted ambience light in accordance with determined content characteristics. The content characterizer is further adapted to determine content characteristics of a global region of the display screen, and the controller is adapted to control the color of the emitted ambience light in accordance with the determined content characteristics of the subregions and of the global region.

The subregions are configured to move from a prior position to a next position and the content characterizer and the controller are adapted for controlling the color of the emitted ambience light in accordance with the determined content characteristics of the image data of subregions of the next position. A dynamic ambience lighting is thereby obtained.
