Techniques and system for active lighting control in video conferencing
First Claim
1. A computer-implemented method, comprising:
- accessing a lighting control system to turn each light in a room on and off individually;
measuring the effect on lighting data in the room when a light is off and when it is on;
storing the measured effect in a lighting profile for the light;
receiving lighting data from a video camera in the room;
comparing the lighting data to a target model comprising a value for at least one parameter;
calculating an adjustment to make to a light in the room when the lighting data is not within a specified range of the target model to approach the target model by;
selecting a light and loading a lighting profile for the selected light;
generating an estimated effect by subtracting the measured effect of the light being on from the lighting data, when the light is on in the room, or adding the measured effect of the light being on to the lighting data, when the light is off in the room;
comparing the estimated effect to the target model; and
selecting the light to adjust when the estimated effect is closer than the lighting data to the target model; and
accessing a lighting control system to adjust the light according to the calculated adjustment.

Abstract
Techniques to provide active lighting control for video teleconferencing systems are described. In an embodiment, a video teleconferencing (TVC) device receives lighting data from cameras in a room where a VTC is taking place. The VTC device may access lighting profiles for the lights in the room from a lighting control system. The VTC device may compare the current lighting conditions to a target model. The VTC device may use the lighting profiles to select lights to turn on or off via the lighting control system to improve the lighting. The VTC device may monitor the lighting conditions during the conference and may re-adjust the lights if a large change occurs. Other embodiments are described and claimed.

8. An article comprising a storage medium containing instructions that when executed cause a system to:
-
access a lighting control system to turn each light in a room on and off individually; measure the effect on lighting data in the room when the light is off and when it is on; store the measured effect in a lighting profile for each light; compare lighting data, received from a video camera in a room, to a target model comprising a value for at least one parameter; calculate an adjustment to make to a light in the room when the lighting data is not within a specified range of the target model to approach the target model by; selecting a light in the room and loading a lighting profile for the selected light; estimating an effect by applying the measured effect of the light from the lighting profile to the lighting data according to whether the selected light is currently on; comparing the estimated effect to the target model; and selecting the light to adjust when the estimated effect is closer than the lighting data to the target model; and access a lighting control system to adjust the light according to the calculated adjustment. - View Dependent Claims (9, 10, 11)

12. An apparatus, comprising:
-
a logic device; a communication interface to communicate with a lighting control system; a lighting optimizing module operating on the logic device to; generate a lighting profile for an individually controllable light source by; measuring the effect on lighting in the room when the individually controllable light source is off and when it is on; and storing the measured effect in a lighting profile for each individually controllable light source; receive lighting data from a video camera in a room, the lighting data comprising at least one parameter; compare the lighting data to an target model comprising a target value for the at least one parameter; calculate an adjustment to make to a light source in the room to approach the target model by; selecting an individually controllable light source and loading a lighting profile for the selected light source; generating an estimated effect by subtracting the measured effect of the light being on from the lighting data when the light is on in the room or adding the measured effect of the light being on to the lighting data when the light is off in the room; comparing the estimated effect to the target model; and selecting the light to adjust when the estimated effect is closer than the lighting data to the target model; and access the lighting control system via the communication interface to adjust the least one light source in the room. - View Dependent Claims (13, 14)
