PURPOSE:To enable high illumination performance with a simple operation by controlling a dimming control system used in one or a plurality of dimming units while separating same from the operation of dimming control system in remaining dimming units. CONSTITUTION:When cross fade is carried out, a desired scene is designated at a control unit 4 irrespective of a scene for performing cross fade. A channel not 0 in its dimming level in this scene is separated from ordinary cross fade according to a channel converting unit 8. A control unit 5 controls operation of the channel converting unit 8 as well as a scene storing unit 6. A fade operating unit 3 controls an illumination load 10 through a dimming unit 9 by operating dimming levels output from the scene storing unit 6 and an output storing unit 7 according to signals from a fader control unit 2. It is thus possible to realize high illumination performance separating only partial illumination from cross fade of the whole illumination with a simple operation. |
