Abstract
A light emitting element driving device includes a receiver that receives a predetermined communication signal transmitted across a communication line, a generator that generates a reference signal based on the start time point of a start bit in the predetermined communication signal, and a determiner that determines, based on the reference signal, the timing of switching a light emitting element from extinction to lighting. The predetermined communication signal is a signal in which the start bit with a first logic level is transmitted at a prescribed period from a transmitter and in which the data bits succeeding each start bit do not have a second logic level a predetermined number of times or more consecutively.
