摘要：
A projector includes: a first light modulation device that modulates illumination light; a second light modulation device that further modulates the illumination light modulated by the first light modulation device; a projection unit that projects the modulated illumination light toward a screen; and an optical device moving unit that moves an optical device blocking at least part of the illumination light relatively to a light path of the illumination light to move the device off the light path in response to an external request.
