Abstract

A projector includes a plurality of light sources, a light modulator that modulates light fluxes emitted from the plurality of light sources based on input information, a projection system that projects modulated light fluxes from the light modulator, a light guiding system that has different areas on which the plurality of light fluxes emitted from the plurality of light sources are incident and guides the plurality of incident light fluxes to the light modulator, a lighting state detector that detects lighting states of the plurality of light sources, and a controller that corrects the input information with correction information based on a viewing angle characteristic of the light modulator in accordance with the lighting states of the plurality of light sources detected by the lighting state detector.
