Abstract:
A projector includes a light source unit having a first light source emitting first wavelength range light and a luminescent wheel having a first wavelength range light transmission area and a luminescent material area receiving the first wavelength range light and reflecting second different wavelength range light provided circumferentially end to end, a light source control unit controlling the light source unit, a display device receiving light from the light source unit to form image light, a pixel shifting unit shifting a display position of the image light for each of a plurality of sub-frame periods forming one image frame period, and a control unit controlling the light source control unit and the pixel shifting unit, the control unit synchronizing a timing the pixel shifting unit shifts the display position for each sub-frame period with a timing the emitted light from the light source unit is switched over.
