PPROBLEM TO BE SOLVED: To attain a data communication faster than conventional visible light communication. PSOLUTION: A light emission control CPU 14 references a light emission pattern table stored in a light emission control information storage section 12 and sets a combination of light emission levels of R, G, B corresponding to a divided bit string (light emission pattern) to an LED driver 19 (S2). An LED driver 19 emits light at a light emission level set by an LED group 17 in the timing in response to the light emission level settings of the R, G, B (S3). When receiving the visible light of the R, G, B emitted at each light emission level, a main CPU 20 of a receiver camera 300 sores each of received luminous quantities Ir, Ig, Ib of the R, G, B to a buffer memory 135. The main CPU 20 particularizes the divided bit string according to the received luminous quantities Ir, Ig, Ib. PCOPYRIGHT: (C)2007,JPO&INPIT
