ABSTRACT:
A light emission control device has a drive current feeder supplying a drive current to a light-emitting element, a drive current controller controlling the current level of the drive current based on the number of pulses in an enable signal, and a resetter resetting the controlling of the current level of the drive current when the enable signal has remained in a predetermined logic state for a predetermined period. Thus configured, the light emission control device allows its turning-on and -off and drive current level to be controlled with a single-line interface.
