Abstract
An object is to provide a terminal device, a communication method, and a communication system which are capable of acquiring accurate optical ID information regardless of the position of the terminal device and the light receiving angle. The terminal device, the communication method, and the communication system according to the present invention each sets a threshold value for the illuminance of a received optical signal by using a moving average method, a weighted moving average method, or an exponential moving average, so that the optical signal can be binarized with a threshold value according to a change in the position of the terminal device, the light receiving angle, or the like. Information from other sensors may be used to set the threshold value.
