Abstract
Official abstract text for this publication.
An image display apparatus includes: a light source that outputs light; a light modulation device that has plural pixels arranged in a matrix and modulates the light from the light source; a projection system that projects the light modulated by the light modulation device onto a projection surface; a pixel image shift unit that can shift positions of images of the pixels of the light modulation device projected on the projection surface; and a control unit that controls the light modulation device and the pixel image shift unit, wherein the control unit can switch whether the pixel image shift unit temporally shifts the positions of the images of the pixels or not.
