摘要： A transmitting method includes: receiving a dimming ratio which is specified for a light source as a specified dimming ratio (S551); 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 (S552). 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.

摘要： A computer-implemented method is provided, in which a plurality of luminance change frequencies of a light emitter is determined by coding one of a plurality of transmission information sources. The light emitter transmits a transmission information source by a change in luminance according to each of the plurality of luminance change frequencies. A signal, which controls the change in luminance of the light emitter according to each of the plurality of luminance change frequencies, is output to the light emitter. The plurality of luminance change frequencies include a first frequency and a second frequency. A signal of the first frequency and a signal of the second frequency respectively cause the light emitter to change in luminance according to the first frequency during a first time period and to change in luminance according to the second frequency during a second time period after the first time period has elapsed.
