Abstract:
1. A multi-display device in which a plurality of image display devices are sequentially arranged and which is operable to display a continuous image, the multi-display device comprising: image-display light-emitting means including light-emitting elements that emit light for displaying the image; light emission brightness data determining means for determining, on the basis of image data displayed by the corresponding image display device, light emission brightness data for the image-display light-emitting means; light emission APL value calculating means for calculating, on the basis of the light emission brightness data, a light emission APL value which is an average lighting ratio of the light-emitting elements; light emission APL value adjusting means for adjusting, on the basis of the light emission APL values calculated by the light emission APL value calculating means each included in a corresponding one of the plurality of image display devices, a reference light emission APL value so that a total light emission power value of the image-display light-emitting means does not exceed a predetermined allowable power value and images are displayed on the plurality of image display devices at predetermined brightness; and light emission control means for controlling power to be supplied to the image-display light-emitting means, on the basis of the light emission APL value calculated by the light emission APL value calculating means or the reference light emission APL value adjusted by the light emission APL value adjusting means.
