ABSTRACT:
A projector includes a lighting device, a first image forming unit including first through third light modulation elements, a second image forming unit including fourth through sixth light modulation elements, a polarization combining optical system, a projection optical system, and an image correction device, wherein the image correction device, based on one of combined transmittance and combined reflectance obtained by combining one of transmittances and reflectances corresponding to gray-scale values of two of the first through sixth light modulation elements for modulating the same colored light beam, outputs the drive value corresponding to the input image data for driving the two light modulation elements corresponding to the predetermined colored light beam.
