Abstract
In a projection apparatus, the synchronization signal generation unit is configured to output synchronization signals for controlling timing of switching a color of light output from the light source unit, the synchronization signals including a synchronization signal used for turning off one of the first and second light-emitting elements in synchronization with the detection signal, and a synchronization signal used for turning on the other light-emitting element at a next period. The control unit is configured to set an interval during which power supplied to the first and second light-emitting elements of the light source unit is stopped at all periods, based on the synchronization signals.
