ABSTRACT:
A video projector includes a laser projection unit that has linear-polarization short-wavelength laser light sources and emits laser lights from the laser light sources, a lens system that collects the laser lights from the laser projection unit, a liquid crystal cell that spatially modulates the collected laser lights, a camera shake correcting optical system that is capable of translating vertically and horizontally on a plane that is perpendicular to the optical axis of the laser projection unit, a prism that transmits the laser lights from the liquid crystal cell and branches the light reflected by the screen, and a camera device that can observe or capture the video image that is branched by the prism. The present invention provides a video projector that can prevent the camera shake and can be held in hands.
