Abstract:
In a transmitting method that enables communication between various devices including devices other than lightings, a luminance change pattern is determined by modulating a visible light signal, a common switch for turning ON, in common, a plurality of light sources which are included in a light source group of a display and are each used for representing a pixel in an image is switched according to the luminance change pattern, and a first pixel switch for turning ON a first light source among the plurality of light sources included in the light source group is turned ON, to cause the first light source to be ON only for a period in which the common switch is ON and the first pixel switch is ON, to transmit the visible light signal.
