Abstract

A visual display system for use in conjunction with a display device includes one or more illumination sources for illuminating a region surround the image display region; and a control unit configured to control the illumination sources to vary the illumination in an inactive state of the display device. The control unit is further configured to synchronize the varying illumination with a color scheme.

Claims

1. A visual display system for use in conjunction with a display device including an image display region, the display device having an active state and an inactive state, the system comprising:

one or more illumination sources disposed in a configuration so that illumination radiated therefrom illuminates an illumination region visually appearing to the viewer to at least partly peripherally surround the image display region; and

a control unit configured to control the one or more illumination sources to vary the illumination of the illumination region in an inactive state of the display device when image data is not presented on the display region, the control unit further being configured to synchronize the varying illumination of the illumination region with a color scheme.

2. The visual display system according to claim 1, wherein the color scheme prescribes a finite duration of the varying illumination of the illumination region, and wherein the control unit is further configured to repeat the varying illumination by repeating the color scheme in a loop.

3. The visual display system according to claim 1, wherein one or more color schemes are pre-installed in a memory of the visual display system.

4. The visual display system according to claim 1, wherein the color scheme is generated based on the image data presented on the display region in an active state of the display device, the color scheme being generated by extracting colors and/or intensities from the image data.

5. The visual display system according to claim 1, wherein the color scheme is generated based on audio data accompanying image data presented on the display region in an active state of the display device, the color scheme being generated by extracting audio parameters from the audio data.

6. The visual display system according to claim 1, wherein the color scheme is generated based on audio data recorded from surroundings of the visual display system captured by a microphone of the visual display system, the color scheme being generated by extracting audio parameters from the audio data.

8. The visual display system according to claim 1, further including a data input port for inputting a color scheme into the system.

7. A visual display system for use in conjunction with a display device including an image display region, the display device having an active state and an inactive state, the system comprising:

one or more illumination sources disposed in a configuration so that illumination radiated therefrom illuminates an illumination region visually appearing to the viewer to at least partly peripherally surround the image display region;

a control unit configured to control the one or more illumination sources to vary the illumination of the illumination region in an inactive state of the display device, the control unit further being configured to synchronize the varying illumination of the illumination region with a color scheme; and

a light-sensitive sensor for detecting a signal indicative of light of surroundings of the visual display system,

wherein intensity of the radiated illumination is modulated by an intensity of the signal detected by the light-sensitive sensor.

9. A method of operating a visual display system, the method comprising the acts of:

providing one or more illumination sources disposed in a configuration so that illumination radiated therefrom illuminates an illumination region visually appearing to a viewer to at least partly peripherally surround an image display region of a display device having an active state and an inactive state; and

controlling the one or more illumination sources to generate a varying illumination of the illumination region in the inactive state of the display device when image data is not presented on the display region, wherein the varying illumination of the illumination region is synchronized with a color scheme.

10. The method of claim 9, wherein intensity of the radiated illumination is modulated by an intensity of a signal detected by a light-sensitive sensor.

11. The method of claim 9, wherein the color scheme is generated based on audio data from surroundings of the visual display system captured by a microphone of the visual display system, the color scheme being generated by extracting audio parameters from the audio data.
