IMAGE PROJECTION APPARATUS
First Claim
1. An image projection apparatus comprising:
- a light modulation element; and
a pixel shift unit configured to shift an optical path of light from a pixel in the light modulation element and to shift a position on a projection surface of a projection pixel formed on the projection surface by a projection optical system with the light,wherein the pixel shift unit includes;
an optical element configured to shift the optical path in one direction among directions orthogonal to an optical axis from the light modulation element to the projection optical system; and
a rotating unit configured to change the one direction by rotating the optical element around the optical axis.
