Abstract: The invention relates to an Ambient illumination system (100), a display device (200), and a method of generating an illumination variation. The ambient illumination system generates the illumination variation using an ambilight signal (A, (A1,1. . . A4,5), P, (P1,1, . . . P4,5)) derived from a video-image (I1, I2), the ambient illumination system comprises an analyzer for deriving the ambilight signals from the video-image and comprises a controller (10) for driving the light source (L1, L2, . . . L8) using the ambilight signal. The illumination variation is displayed by the controller while not displaying the video-image.

Abstract: The present invention relates to a loudspeaker cover comprising a light guide arranged for receiving light from a light source, wherein the light guide comprises at least one hole to allow sound to be emitted through the cover, and wherein the at least one hole is arranged for dispersing the received light out of the light guide. The holes in the light guide may e.g. be cylindrical, conical, double-conical, or formed as grooves. The invention further relates to a loudspeaker housing comprising such a loudspeaker cover, and an electronic entertainment device comprising such a loudspeaker cover. In a preferred embodiment, the loudspeaker cover is positioned adjacent to a display. In case light is emitted that matches the contents being shown on the periphery of the display, this effect is even further enhanced in that the colors are perceived as leaking out of the display onto the loudspeaker cover. The effect of the dispersed light is a larger virtual display and a more immersive viewing experience.

Abstract: This invention relates to an ambient lighting system for a display device including an image display region. Controllable light sources that are substantial point-like and disposed in an array are provided, each being adapted to emit a light beam of at least one wavelength onto an region visually appearing to the viewer peripherally surrounding the display. An image analyzer determines the color information from video data of the displayed image, the color information being used as a control parameter for controlling the emission color of the emitted light beams. Due to the substantial point-like property of the light sources along with their arrangement within the array the emitted light beams onto the region forms a pixelated image so as to provide at least a partial extension of the image display region.
