SOLUTION: In a storage unit 4, data is set in order of address so that stored values flicker and change. A read-out unit 3 reads out data of the storage unit in order of address and generates a light adjustment signal in which a signal value flickers and changes with an elapse of time. A light adjustment device 2 is controlled by means of this light adjustment signal, and the light output of a light source 1 is controlled according to the light adjustment signal. As a result, the light output of the light source 1 flickers and changes with an elapse of time.</p> |
