RECEIVER, TRANSMITTER AND COMMUNICATION SYSTEM

According to one embodiment, a receiver includes an image sensor, a synchronization controller, and a data generator. The image sensor detects a visible ray having a lattice-shaped emission pattern. The synchronization controller determines whether it is necessary to generate data based on a first synchronized visible ray located at a first lattice corner of the emission pattern and a second synchronized visible ray located at a second lattice corner. The second lattice corner is an opposite corner to the first lattice corner. The data generator generates the data corresponding to a data visible ray located at a lattice point other than the first lattice corner and the second lattice corner when the synchronization controller determines that it is necessary to generate the data.
