Abstract:
A projector that projects and displays a color image, the projector comprising:an illumination optical system that emits illumination light; a color light separation optical system that divides the illumination light emitted from the illumination optical system into first through third color lights, which respectively have three different color components; first through third electro-optical devices that respectively modulate the first through the third color lights, which are separated by the color light separation optical system, in response to first through third image signals and thereby generate first through third modulated lights; a color light synthesizing optical system that synthesizes the first through the third modulated lights with one another and emits synthesized light; a projection optical system that projects the synthesized light emitted from the color light synthesizing optical system; a relay optical system that is provided in one optical path selected out of three optical paths, which respectively connect the color light separation optical system with the first through the third electro-optical devices, the relay optical system regulating a size of a light bundle of a selected color light; and an adjustment section that adjusts a specific image signal, which is one out of the first through the third image signals and corresponds to the electro-optical device that receives the selected color light passing through the relay optical system, a degree of the adjustment being depend on pixel positions of a color image so that cross sectional luminance distributions of the first through the third modulated lights on a light-exiting side of the color light synthesizing optical system have substantially same gradients at least when the first through the third image signals reproduce a white image.
