Abstract
A transmitting method includes: receiving a dimming ratio which is specified for a light source as a specified dimming ratio (S); transmitting a signal encoded in a first mode by changing luminance while causing the light source to emit light at the specified dimming ratio when the specified dimming ratio is less than or equal to a first value; and transmitting the signal encoded in a second mode by changing the luminance while causing the light source to emit light at the specified dimming ratio when the specified dimming ratio is greater than the first value (S). Here, a peak current value of the light source when the specified dimming ratio is greater than the first value and less than or equal to a second value is less than the peak current value of the light source when the specified dimming ratio is the first value.
