Document Type and Number:
WIPO Patent Application WO/2019/189768
Kind Code:
A1
Abstract:
Provided is a communication method that enables communication between various apparatuses. This communication method includes: determining whether or not a terminal can perform visible light communication (step SG11); when it is determined that the terminal can perform visible light communication (Yes in step GS11), acquiring an image for decoding by imaging a luminance-varying subject using an image sensor, and acquiring first identification information transmitted by the subject from a stripe pattern appearing in the image for decoding (step SG12); and, when it is determined in the determination of visible light communication that the terminal cannot perform visible light communication (No in step SG11), acquiring a captured image by imaging the subject using the image sensor, specifying a prescribed specific region by detecting edges of the captured image, and acquiring second identification information transmitted by the subject from a line pattern in the specific region (step SG13).
