Projector device and projection method thereof

Abstract

A projector device includes: a light modulating element which modulates light from a light source section according to an image signal; a projecting section which projects a modulation light modulated by a displayable region in a surface of an effective region of the light modulating element onto a projection surface; a trapezoidal distortion correcting section which corrects trapezoidal distortion of a projection image projected onto the projection surface by projecting a light modulation image by means of the displayable region by an after-correction image region which is a part of the effective region of the light modulating element; and a position adjusting section which adjusts the position of the projection image projected onto the projection surface by moving the after-correction image region in the surface of the effective region while maintaining the size and shape of the after-correction image region.
