Abstract

See full text

A projector includes a first light source group having a plurality of solid-state light sources, a second light source group having a plurality of solid-state light source, and emitting light having a peak wavelength on a longer wavelength side of that of the first light source group, a first regulation section adapted to cool the first light source group, a second regulation section adapted to cool the second light source group, and a control device adapted to control the first regulation section and the second regulation section, and the first regulation section and the second regulation section are controlled so as to approximate the peak wavelengths of the lights emitted respectively from the first light source group and the second light source group to each other when forming a two-dimensional image, or to make the peak wavelengths get further from each other when forming a three-dimensional image.
