<p><P>PROBLEM TO BE SOLVED: To provide an illumination control device where a control delay between lines is made to hardly outstand even when luminaires in the plurality of lines can not be light-modulated at the same time; and to provide an illumination system. <P>SOLUTION: This illumination control device 1 is provided with: a plurality of lines of light modulation signal output parts 14a-14d for outputting light modulation signals to luminaires 2a-2d capable of being subjected to light modulation control, respectively; and a control part 11 for controlling brightness levels of the light modulation signals outputted from the light modulation signal output parts 14a-14d of the respective lines. When the control part 11 changes the brightness levels of the light modulation signals outputted from the light modulation signal output parts 14a-14d of the respective lines to target values set on a system basis one-by-one, the lower the brightness level of the light modulation signal outputted from any of the light modulation signal output parts 14a-14d becomes, the higher the priority thereof is set; and the brightness levels are sequentially changed from the light modulation signal output part 14a, 14b, 14c or 14d having the highest priority. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
