Abstract:
A projector including a first light source, a second light source that emits light having a color different from the first light source, a light modulator that modulates the light emitted from each of the first and the second light sources, and a controller that controls a first operation state in which the first and the second light sources are driven based on time division driving to perform image display and a second operation state in which the first and the second light sources are driven based on time division driving to perform illumination, wherein in the second operation state, a switching frequency at which the first and the second light sources are switched from one to the other is higher than a switching frequency at which the first and the second light sources are switched from one to the other in the first operation state.
