    • 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.
    • 照明控制系统包括:具有各自地址的照明装置,并且响应于从外部输入的调光信号进行调光控制;以及照明控制终端,其具有成像装置,其拍摄范围被设定为包括照明范围 照明装置。 照明控制终端将由成像装置拍摄的图像分割成多个区域,使得这些区域对应于照明范围,基于拍摄图像检测人物,如果该人具有,则确定该人在其中存在的分割区域 并对对应于所确定的分段区域的照明装置执行调光控制。

    • 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.
    • 照明装置包括光源; 传感器,其具有图像传感器,并且在设置与由所述光源照射的范围重叠的范围作为视野的同时基于拍摄图像来检测照度和人的存在; 照度确定单元,用于根据照度和人的存在来改变从光源输出的光; 和调光控制单元。 照度判定部基于拍摄图像获得包含在视野中的照度维持区域的照度,当传感器不检测到人时,照度决定单元将照度保持区域的照度保持为 等于或大于预先设置为下限照度的阈值,这使得图像传感器捕获图像变得可行。
