Claim Text:
1. A pairing method which pairs a first electronic device with a second electronic device, each electronic device including a communication unit to communicate data and a light receiving unit to detect a received light amount of light received thereby, the method comprising: judging whether or not the received light amount detected by the light receiving unit of each of the first electronic device and the second electronic device satisfies a predetermined light receiving environment condition; setting the first electronic device and the second electronic device to a pairing standby state when it is judged that the received light amount detected by the light receiving unit of each of the first electronic device and the second electronic device satisfies the predetermined light receiving environment condition; detecting a changing of a light intensity on the light receiving unit of the first electronic device and on the light receiving unit of the second electronic device under a same light receiving environment; transmitting, from the second electronic device to the first electronic device, time series data of the received light amount detected by the light receiving unit of the second electronic device in the detected changing of the light intensity; and pairing the first electronic device with the second electronic device based on time series data of the received light amount detected by the light receiving unit of the first electronic device in the detected changing of the light intensity and the time series data of the received light amount transmitted from the second electronic device.
