Claim 15:
16. The light emission control device according to claim 12, wherein
before the fulfillment of the predetermined condition, all the light-emitting elements in the light-emitting element arrays are in the extinguished state, 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 increases 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 increases the number of light-emitting elements lit in the light-emitting element array at time intervals synchronous with the another clock signal.
