LIGHT EMISSION CONTROL SYSTEM, LIGHT EMISSION SYSTEM, LIGHT EMISSION CONTROL DEVICE, AND LIGHT EMISSION DEVICE

In a first light emission control device, a clock signal is generated, and after a first driving sequence starts to be performed in which the respective states of light-emitting elements in a first light-emitting element array are sequentially switched synchronously with the clock signal, at a particular time point a characteristic of the clock signal is changed from a first characteristic to a second characteristic. After the change, in a second light emission control device, a second driving sequence is performed in which the respective states of light-emitting elements in a second light-emitting element array are sequentially switched synchronously with the clock signal.
