A lighting device comprises an array of controllable light emitting pixels, each pixel having an adjustable light output colour. A controller is configured to receive a limited set of light output colours and to locally process these light output colours to form a colour gradient pattern to be displayed across pixels of the array.

Lighting device and control method

A lighting system () for controlling an LED array () is disclosed. The lighting system () comprises the LED array () comprising a plurality of individually addressable light sources L-Leach having an individual address, a processor () configured to divide the plurality of individually addressable light sources L-Linto a plurality of segments () of light sources by assigning segment addresses to the segments () of light sources, wherein each segment comprises a unique set of one or more light sources, wherein the LED array () further comprises a receiver () configured to receive a plurality of lighting control signals via a network (), wherein each lighting control signal is addressed to one of the segment addresses, and wherein the LED array () further comprises a controller () configured to control at least one of the individually addressable light sources of each segment according to the lighting control signal addressed to the respective segment.

Lighting system for controlling an LED array

A device and method process graphics to be overlayed over video for three-dimensional display. The video includes a series of video frames updated at a video rate, including main video frames and additional video frames. A first buffer buffers a first part of the overlay information to be overlayed over the main video frames. A second buffer buffers a second part of the overlay information to be overlayed over the additional video frames. For each video frame, the first part of the overlay information or the second part of the overlay information is copied to a frame-accurate area copier. The first part of the overlay information or the second part of the overlay information is output according to whether a current video frame is a main video frame or an additional video frame. The first part of the overlay information and the second part of the overlay information are updated at an overlay rate. The overlay rate is different than the video rate.

Method and device for overlaying 3D graphics over 3D video

A method of decoding and outputting video information suitable for three-dimensional [3D] display, the video information comprising encoded main video information suitable for displaying on a 2D display and encoded additional video information for enabling three-dimensional [3D] display, the method comprising: receiving or generating three-dimensional [3D] overlay information to be overlayed over the video information; buffering a first part of the overlay information to be overlayed over the main video information in a first buffer; buffering a second part of overlay information to be overlayed over the additional video information in a second buffer; decoding the main video information and the additional video information and generating as a series of time interleaved video frames, each outputted video frame being either main video frame or additional video frame; determining a type of an video frame to be outputted being either a main video frame or an additional video frame; overlaying either first or second part of the overlay information on an video frame to be outputted in agreement with the determined type of frame outputting the video frames and the overlayed information.
