Illumination control apparatus
First Claim
1. An illumination control apparatus configured to control brightness of a plurality of illumination devices provided in a plurality of sections, respectively, comprising:
- a detection unit configured to detect presence or absence of a person in each of the plurality of sections based on an output of a video camera configured to take images of the plurality of sections; and
a control unit configured to;
turn on an illumination device of a detected section among the plurality of illumination devices, the detected section being a section where a person is detected,turn off an illumination device of a section other than the detected section and an adjacent section among the plurality of illumination devices, the adjacent section being a section adjacent to the detected section, andcontrol brightness of the illumination device of the adjacent section so that illuminance of the detected section becomes predetermined illuminance, whereinin a state where the illumination device of the detected section is on and the illumination device of a section other than the detected section and the adjacent section is off, the control unit controls the brightness of the illumination device of the adjacent section based on information indicating brightness of the illumination device of the adjacent section calculated so that the illuminance of the detected section becomes the predetermined illuminance.
