VISIBLE LIGHT COMMUNICATION DEVICE AND METHOD

PROBLEM TO BE SOLVED: To provide a visible light communication device capable of quickly acquiring only a communication signal desired by a recipient even when a plurality of light sources for communication are included in an imaging range. SOLUTION: A light source for communication detecting part 14 for detecting a light source for communication analyzes an imaged image obtained by an imaging part 12 and outputs the position and area information of a light source for communication. A variation calculating part 15 detects a correspondence relation between frames of a detected light source for communication and calculates the variation of the position and area of the light source for communication of the light source for communication. A priority determining part 16 sets a processing priority of the light source for communication in accordance with the variation of the position and the area. A communication signal detecting part 19 detects an optical communication signal from the light source for communication, and outputs communication information. A display control part 20 synthesizes only communication information corresponding to the light source for communication having a high processing priority with the imaged image and outputs and displays the communication information.
