CLAIMS:

1. A system (1,21,40) for dynamically controlling settings of a plurality of lighting devices (15-17,45-47) in a spatial area in which a video call takes place, said system (1,21,40) comprising:

at least one input interface (3,23,53);

at least one control interface (4,24,54); and

at least one processor (5,25,55) configured to:

- detect that a mobile device (1, 11) is being used for video calling,

- use said at least one input interface (3,23,53) to determine at least one parameter for each of said plurality of lighting devices (15-17,45-47) from at least one input signal, said at least one parameter depending on a spatial location of said lighting device (15-17,45-47) relative to a spatial location of said mobile device (1,11),

- determine settings, to enhance the quality of the video captured by the mobile device, for said plurality of lighting devices (15-17,45-47) based on said determined parameters,

- use said at least one control interface (4,24,54) to control said plurality of lighting devices (15-17,45-47) according to said determined settings upon detecting that said mobile device (1, 11) is being used for video calling,

- detect that said mobile device (1,11) is no longer being used for video calling, and

- use said at least one control interface (4,24,54) to control said plurality of lighting devices (15-17,45-47) according to different settings upon detecting that said mobile device (1,11) is no longer being used for video calling, wherein said different settings are settings used by said plurality of lighting devices (15-17,45-47) before said plurality of lighting devices (15-17,45-47) were controlled according to said determined settings.

2. A system (1,21,40) as claimed in claim 1, wherein said at least one parameter comprises a distance parameter which represents a distance between said lighting device (15-17,45-47) and said mobile device (1,11).

3. A system (1,21,40) as claimed in claim 2, wherein said at least one processor

(5,25,55) is configured to determine a set of said plurality of lighting devices (15-17,45-47) with a distance smaller than a threshold based on said determined distance parameters and determine a dimmed light setting for said set of lighting devices.

4. A system (1,21,40) as claimed in claim 2, wherein said at least one processor

(5,25,55) is configured to determine a first set of said plurality of lighting devices (15-17,45-47) with a distance smaller than a threshold and a second set of said plurality of lighting devices (15-17,45-47) with a distance larger than said threshold based on said determined distance parameters and determine a first set of light output levels for said first set and a second set of light output levels for said second set, each of said light output levels in said first set being higher than each of said light output levels in said second set.

5. A system (1,21,40) as claimed in claim 1 or 2, wherein said at least one parameter comprises a direction parameter which indicates whether said lighting device (15-17,45-47) is located in front of a person holding said mobile device (1,11) or behind a person holding said mobile device (1,11).

6. A system (1,21,40) as claimed in claim 5, wherein said at least one processor

(5,25,55) is configured to determine said direction parameter based on an orientation of said mobile device (1,11).

7. A system (1,21,40) as claimed in claim 5, wherein said at least one processor

(5,25,55) is configured to determine a first set of said plurality of lighting devices (15-17,45-47) in front of said person and a second set of said plurality of lighting devices (15-17,45-47) behind said person based on said determined direction parameters and determine a first set of light output levels for said first set and a second set of light output levels for said second set, each of said light output levels in said first set being higher than each of said light output levels in said second set.

8. A system (1) as claimed in claim 1 or 2, wherein said system (1) comprises said mobile device (1) and said at least one processor (5) is configured to receive said at least one input signal from each of said plurality of lighting devices (15-17).

9. A system (40) as claimed in claim 1 or 2, wherein said system (40) comprises said plurality of lighting devices (45-47) and said at least one processor (55) is configured to receive said at least one input signal from said mobile device (11).

10. A system (21) as claimed in claim 1 or 2, wherein said at least one processor (25) is configured to receive a first input signal of said at least one input signal from said mobile device (11) and further input signals of said at least one input signal from said plurality of lighting devices (15-17).

11. A system (1,21,40) as claimed in claim 1 or 2, wherein said at least one processor (5,25,55) is configured to determine a spatial location of said lighting device (15-17,45-47) relative to a spatial location of said mobile device (1,11) based on radio frequency transmissions by multiple devices.

12. A method of dynamically controlling settings of a plurality of lighting devices in a spatial area in which a video call takes place, said method comprising:

- detecting (101) that a mobile device is being used for video calling;

- determining (103) at least one parameter for each of said plurality of lighting devices from at least one input signal, said at least one parameter depending on a spatial location of said lighting device relative to a spatial location of said mobile device;

- determining (105) settings, to enhance the quality of the video captured by the mobile device, for said plurality of lighting devices based on said determined parameters;

- controlling (107) said plurality of lighting devices according to said determined settings upon detecting that said mobile device is being used for video calling,

- detecting that said mobile device (1,11) is no longer being used for video calling, and

- using said at least one control interface (4,24,54) to control said plurality of lighting devices (15-17,45-47) according to different settings upon detecting that said mobile device (1,11) is no longer being used for video calling, wherein said different settings are settings used by said plurality of lighting devices (15-17,45-47) before said plurality of lighting devices (15-17,45-47) were controlled according to said determined settings.

13. A computer program or suite of computer programs comprising at least one software code portion or a computer program product storing at least one software code

portion, the software code portion, when run on a computer system, being configured for enabling the method of claim 12 to be performed.
