Abstract
A projector that projects an image based on image data, includes alight source, a modulation unit that modulates light which is emitted from the light source, a light attenuation rate setting unit that sets a light attenuation rate based on the image data, and a light adjustment unit that adjusts intensity of incident light of the modulation unit, according to the light attenuation rate which is set by the light attenuation rate setting unit. The light attenuation rate setting unit sets a minimum value of an adjustment range of the light adjustment unit in a case where the image data is stereoscopic image data to a higher value than a minimum value of an adjustment range of the light adjustment unit in a case where the image data is not stereoscopic image data.
