Abstract
A time-division image projector includes a light source radiating white light, a transmission color wheel, with color filters transmitting light of specific wavelength bands, a reflection element where the normal of the reflecting surface is at an inclination to light irradiated onto transmission color wheel and reflects light of specific wavelengths transmitted by color filters in a different direction, an optical modulation element supplied, in time divisions, with image signals corresponding to light of specific wavelengths reflected by reflection element and modulates, the intensity of light of the specific wavelength bands transmitted by color filters according to image signals, projection lens projecting light emitted from optical modulation element, and a motor linked to an axis of rotation of the transmission color wheel causing the transmission color wheel to rotate in synchronism with the supply of the image signals corresponding to the light of the specific wavelengths.
