Abstract:
1. A projector comprising: a first image projection section adapted to project a first image based on a first image signal; a second image projection section adapted to project a second image based on a second image signal such that pixels of the second image are shifted from pixels of the first image; a correction section adapted to correct the image signal input to the image projection section using a correction filter adapted to correct a difference in optical transfer function between the plurality of image projection sections; and a sharpening section adapted to execute a sharpening process of sharpening an edge portion of the image to be displayed, on the image signal having been corrected by the correction section and to be input to the plurality of image projection sections, wherein the correction section takes the optical transfer function of either one of the plurality of image projection sections as a reference optical transfer function, and corrects the image signal input to the rest of the plurality of image projection sections using the correction filter adapted to correct a difference in optical transfer function of the rest of the plurality of image projection sections with respect to the reference optical transfer function.
