20120319596 | ILLUMINATION CONTROL SYSTEM - An illumination control system includes: illumination apparatuses having respective addresses and perform a dimming control in response to a dimming signal inputted from an outside, and an illumination control terminal which has an imaging device, a capturing range of which is set to include illumination ranges of the illumination apparatuses. The illumination control terminal segments an image captured by the imaging device into a plurality of areas so that the areas correspond to the illumination ranges, detects a person based on the captured image, determines a segmented area in which the person is present if the person has been detected and performs dimming control on an illumination apparatus corresponding to the determined segmented area. | 12-20-2012 |
20120326611 | ILLUMINATION APPARATUS - An illumination apparatus includes a light source; a sensor which has an image sensor and detects an illuminance and a presence of a human based on a captured image while setting a range overlapping a range illuminated by the light source as a visual field; an illuminance determining unit for varying a light output from the light source based on the illuminance and the presence of a human; and a dimming control unit. The illuminance determining unit obtains an illuminance of an illuminance maintaining area included in the visual field based on the captured image, and when the sensor detects no human, the illuminance determining unit reduces the light output while maintaining the illuminance of the illuminance maintaining area to be equal to or greater than a threshold that is set in advance as a lower limit illuminance, which makes it feasible for the image sensor to capture an image. | 12-27-2012 |
