Abstract

Official abstract text for this publication.

An optical communication method is an optical communication method for performing optical communication with a light-emitting device serving as a communication target. The optical communication method includes: a first step of reading information relating to a distance to the light-emitting device and information relating to a size of a light-emitting region included in the light-emitting device, the information relating to the distance and the information relating to the size being stored in advance; a second step of controlling an imaging range of a camera based on the information relating to the distance and the information relating to the size, the camera capturing an image of light from the light-emitting device; and a third step of extracting a signal from light emitted from the light-emitting device based on image data that the camera has captured in the imaging range.

First claim

Opening claim text (preview).

What is claimed is: 1. An optical communication method for performing optical communication with a light-emitting device serving as a communication target, the optical communication method comprising: a first step of reading information relating to a distance to the light-emitting device and information relating to a size of a light-emitting region included in the light-emitting device, the information relating to the distance and the information relating to the size being stored in advance; a second step of controlling an imaging range of a camera based on the information relating to the distance and the information relating to the size, the camera capturing an image of light from the light-emitting device; and a third step of extracting a signal from light emitted from the light-emitting device based on image data that the camera has captured in the imaging range. 2. The optical communication method according to claim 1 , wherein in the second step, a cut-out range that will be cut out from the imaging range is determined based on the information relating to the distance and the information relating to the size, and processing for cutting out image data that corresponds to the cut-out range is performed on the image data captured by the camera, and in the third step, the signal is extracted from the light emitted from the light-emitting device based on the image data that has been cut out.
