Abstract
A projector includes a light source; a spatial light modulation device which modulates light from the light source according to an image that is written; a light diffusion device which adjusts a degree of diffusion of the light incident on the spatial light modulation device or the light emitted from the spatial light modulation device; and a light diffusion controller which controls the light diffusion device so that the light diffusion device diffuses the light when the light source starts to light up.
