LIGHTING SYSTEM
First Claim
1. A lighting system comprising a plurality of controllers each configured to control one or more lighting apparatuses,whereineach of the lighting apparatuses has an address specific thereto,each of the lighting apparatuses includes:
- a first communication unit configured to communicate with the controller selecting the corresponding lighting fixture as a control object;
a light source; and
a first control unit configured to light the light source, each of the controllers includes;
an image sensor configured to take an image of a lighting area of the lighting apparatus selected as the control object of the corresponding controller;
an image processing unit configured to detect presence of a person in the image taken by the image sensor, and the image processing unit being configured to, upon detecting a person, determine a set of coordinates of a position of the detected person;
a second control unit configured to operate the lighting apparatus selected as the control object of the corresponding controller according to a detection result from the image processing unit; and
a second communication unit configured to communicate with the lighting apparatus selected as the control object of the corresponding controller,each of the controllers is configured toassociate the set of coordinates of a position in the image taken by the image sensor of the controller with the address of the lighting apparatus selected as the control object of a particular controller out of the other controllers, andeach of the controllers is configured towhen a person is detected by the image processing unit of the controller, determine the set of coordinates of a position of the detected person, andwhen the lighting apparatus associated with the determined set of coordinates is the control object of the particular controller, send a control signal to the particular controller, andthe particular controller is configured to, upon receiving the control signal, light the lighting apparatus associated with the determined set of coordinates.

Abstract
The lighting system includes a plurality of controllers each configured to control one or more lighting apparatuses. Each controller is configured to associate a set of coordinates of a position in an image taken by an image sensor thereof with an address of the lighting apparatus selected as a control object of a particular controller out of the other controllers. Each controller is configured to, when a person is detected by the image processing unit thereof, determine the set of coordinates of a position of the detected person; and, when the lighting apparatus associated with the determined set of coordinates is the control object of the particular controller, send a control signal to the particular controller. The particular controller is configured to, upon receiving the control signal, light the lighting apparatus corresponding to the determined set of coordinates.
