Patent ID: 8876302

Claim:
A projector comprising: a light modulation unit that modulates illumination light; a projection unit that projects image light modulated by the light modulation unit; and a holder that holds an optical filter and a cover in such a way that the optical filter and the cover can be alternately switched and positioned in an optical path on the light-exiting side of the projection unit, wherein: the cover includes at least a light-transmissive cover glass, and the projector further comprises a display controller that adjusts how the light modulation unit modulates light in accordance with which of the optical filter and the cover glass is positioned in the optical path on the light exiting-side of the projection unit, such that the light modulation unit modulates light according to a first type of color correction when the optical filter is positioned in the optical path and the light modulation unit modulates light according to a second type of color correction when the cover glass is positioned in the optical path.
