Patent ID: 8807756

Claim:
A laser projector, comprising: a laser light source; a two-dimensional light modulator for modulating light from the laser light source; a projection optical system for projecting images on a display plane by expanding the light modulated by the two-dimensional light modulator; a driver which shifts the projection optical system in a direction perpendicular to an optical axis of the light modulated by the two-dimensional light modulator or in a direction of the optical axis; and a controller which controls the two-dimensional light modulator and the driver, wherein the two-dimensional light modulator shifts a display position of an image in the two-dimensional light modulator, a shift of a display position of the two-dimensional light modulator, and a shift of at least a part of the projection optical system are performed in synchronization with each other so that display positions of the images on the display plane are made identical to each other when the display position of the image in the two-dimensional light modulator is shifted, and the controller controls the two-dimensional light modulator to change a pixel region of the two-dimensional light modulator, wherein each pixel of the display plane is displayed using a plurality of pixels spaced apart from each other by a distance corresponding to one pixel or more on the two-dimensional light modulator, and the controller controls the driver to shift the projection optical system in the direction perpendicular to the optical axis or in the direction of the optical axis in synchronism with the change of the pixel region of the two-dimensional light modulator.
