A light emission control device controls a first switching element of a light source circuit including a first resistor, a light emitting element, and the first switching element coupled in series between a first power supply node and a second power supply node set to a lower potential than the first power supply node. The light emission control device includes a second detection circuit that compares a first potential difference between both ends of the first resistor with a determination value, a light emission control circuit that outputs a first control signal that controls on/off of the first switching element, and a logic determination circuit that determines whether or not the first switching element is short-circuited. The light emission control circuit sets the first control signal to a first drive stoppage state that inactivates the first control signal, and when the second detection circuit has detected that the first potential difference is larger than the determination value, the logic determination circuit outputs an error signal.
