Abstract: An optical communication device is provided. The optical communication device includes at least one light source and a controller configured to continuously control, by a light source control signal, each of the at least one light source to operate in at least two modes. The at least two modes include a first mode and a second mode. The first mode is used to transfer a first information, and the second mode is used to transfer a second information different from the first information. For any one of the at least one light source, in the first mode, the light source control signal has a first frequency so that a stripe presents in a first image of the light source obtained when the light source is photographed by a CMOS image sensor, and in the second mode, a second image of the light source obtained when the light source is photographed by the CMOS image sensor is substantially free from any stripe.
