PURPOSE:To improve the effect of display through graphic image by storing an image signal in a magnetic tape, by playbacking it through a first magnetic tape playback means, by storing a dimming level obtained from every lighting load, in a magnetic tape, and by playbacking it through a second magnetic tape playback means. CONSTITUTION:An image from a first VTR 3 is displayed by a screen 21, while sound output is playbacked by speakers 22a, 22b. A second VTR 7 is controlled by the first VTR 3 through a synchronizer 8. Signals indicating dimming levels for lighting loads 4a-4c, which are synchronized by the synchronizer 8, are playbacked in order by the second VTR 7. Signals indicating dimming levels from the second VTR 7 in order, are lead out for every lighting load 4a-4c by a decoder 9, and the dimming thereof is thus controlled. Each lighting load 4a-4c is arranged at a predetermined position in a display booth 20, and the dimming thereof is controlled in a synchronous mode with an image in the screen 21, and the atmosphere in the display booth 20 is adjusted in a synchronous mode with the image in the screen 21. |
