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.

Abstract: In a projector, a controller sets a start timing and an end timing of a color transitional period which includes the color switch timing in a center of the color transitional period, and sets one of the start timing and the end timing to coincide with a light source switch timing at which the color of the light emitted by the light source unit switches. A projection drive unit controls the display drive of the display element based on the start timing and the end timing.
