description A transmitting device includes a lighting device changing a first characteristic and a second characteristic of light to be emitted along time series; and a control device controls, in a period having a first time length, the lighting device to modulate the first characteristic of the light emitted from the lighting device in the time series in accordance with a light emission pattern having a waveform according to information to be transmitted and having the first time length, controls the lighting device to perform pulse modulation with a pulse pattern having a second time length shorter than the first time length for the second characteristic in accordance with the information, and sets peak and bottom values of the second characteristic of each pulse included in a subsection, for an average of the second characteristic to be a value maintaining the waveform of the light emission pattern.
