<p><P>PROBLEM TO BE SOLVED: To represent fluctuation close to a natural phenomenon by using a light emitting device having light emitting elements one-dimensionally arranged in a line, and to sufficiently easily generate control data for controlling its luminance. <P>SOLUTION: A control procedure 200 shows a procedure generating the control data for controlling the luminance Z of an LED of each color (red, green, blue) of each emission unit. An argument k of an arrangement in each step corresponds to a serial number k of each light emitting unit one to one, and each process is sequentially carried out within the limit (1≤αk≤60) respectively. By these processes, a chaos arithmetic operation based on logistic mapping of a formula (6) y(k, n+1)=4.0×y(k, n)×ä1.0-y (k, n)} is performed, where the time n corresponds to the loop count. By repeating these processes periodically every 400 milliseconds, the control data expressing fluctuation of young leaves can be generated in real time. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
