Claim 16:
17. The light emission control device according to claim 12, wherein
with the fulfillment of the predetermined condition, the controller light all the light-emitting elements in the light-emitting element array, and
the controller is configured such that,
in the first mode, after the fulfillment of the predetermined condition, in the first driving sequence, the controller sequentially reduces a number of light-emitting elements lit in the light-emitting element array at time intervals synchronous with the clock signal, and,
in the second mode, in the second driving sequence, the controller sequentially reduces the number of light-emitting elements lit in the light-emitting element array at time intervals synchronous with the another clock signal.
