Title:
LIGHT-EMITTING DEVICE, PHOTORECEIVER, INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2018121169
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable an optical communication suitable for transmission of information with high confidentiality.SOLUTION: A light-emitting device 100 emits light with a hue value changed from a reference value in regard to a hue value of light of each of Red(R), Green(G) and Blue(B) when emitting light according to a light emission pattern corresponding to a light signal packet format. The photoreceiver 200 performs a process to restore hue values of Red(R), Green(G) and Blue(B) in a color change region back to reference values as to a plurality of frames of a period corresponding to the light signal packet format, decodes a bit data array corresponding to hue values, and acquires information of a communication target for each of the colors of Red(R), Green(G) and Blue(B) of which the hue values are restored to reference values.SELECTED DRAWING: Figure 1
