TRANSMITTING METHOD, TRANSMITTING APPARATUS, AND PROGRAM
First Claim
1. A transmitting method of transmitting a visible light signal by way of luminance change, the transmitting method comprising:
- determining a luminance change pattern to transmit the visible light signal;
switching a common switch according to the luminance change pattern, the common switch being for turning ON a plurality of light sources in common; and
turning ON a first pixel switch for turning ON a first light source, to cause the first light source to be ON for a period in which the common switch is ON and the first pixel switch is ON, to transmit the visible light signal, the first light source being one of the plurality of light sources,in the turning ON of a first pixel switch, when the image is displayed on the display, the first pixel switch is switched to increase a lighting period that corresponds to the first light source, to compensate a period in which the first light source is OFF for transmission of the visible light signal.

Abstract
A visible light signal transmitting method includes: determining a luminance change pattern to transmit the visible light signal; switching a common switch according to the luminance change pattern, the common switch being for turning ON a plurality of light sources in common; and turning ON a first pixel switch, to cause the first light source to be ON for a period in which the common switch is ON and the first pixel switch is ON, to transmit the visible light signal, the first light source being one of the plurality of light sources. In the turning ON of a first pixel switch, when the image is displayed on the display, the first pixel switch is switched to increase a lighting period that corresponds to the first light source, to compensate a period in which the first light source is OFF for transmission of the visible light signal.
