Abstract

A lighting system (100) includes light sources (110) and a user interface (130) configured to display an image of an environment including an object provided with a first illumination. The image may be provided by a camera (140) to a remote display device (260). A processor (120) may be configured to change the first illumination to a second illumination in response to a signal and to select at least one of the light sources to provide the second illumination based on attributes of the second illumination and availability and specifications of the light sources. The signal may be provided by a user viewing the image. Alternatively or in addition, the processor (120) may be further configured to generate the signal by detecting a change of the object using content analysis of the image in comparison with a previous image.

Claims

1. A lighting system comprising:

a plurality of light sources;

a user interface configured to display an image of an environment including an object provided with a first illumination; and

a processor configured to generate a signal by detecting a change in the appearance of the object using content analysis of the image in comparison with a previous image and to change the first illumination to a second illumination in response to the signal and to select at least one of the plurality of light sources to provide the second illumination based at least in part on attributes of the second illumination and availability and specifications of the light sources.

2. The lighting system of claim 1, further comprising a camera configured to monitor the environment and provide the image.

3. A method of controlling a lighting system including light sources comprising:

displaying an image of an environment including an object provided with a first illumination;

changing the first illumination to a second illumination in response to a signal and to select at least one of the light sources to provide the second illumination based on attributes of the second illumination and availability and specifications of the light sources; and

detecting a change of the object using content analysis of the image in comparison with a previous image to generate the signal.

4. The method of claim 3, further comprising:

monitoring the environment; and

providing the image to a display located remotely from the environment.

5. A lighting system comprising:

a light source configured to illuminate an object at a first location in an environment; and

a processor configured to detect a change in the environment including a change of location of the object from the first location to a second location, and to select a further light source for illumination of the object at the second location based on attributes of the illumination and availability and specifications of light sources, wherein the processor is to detect the change based on content analysis of a current image of the environment in comparison with a previous image of the environment.

6. The lighting system of claim 5, further comprising a camera configured to monitor the environment and provide an image of the environment to a display located remotely from the environment.

7. The lighting system of claim 6, further comprising a user interface configured to display the image of the environment.
