An original image is divided into a plurality of image parts in the forms of image signals which are then given to liquid crystal light valves, respectively so that liquid crystal light valves display the plurality of image parts therein. These liquid crystal light valves allow light from light sources to pass through so as to form image light beams which are intensity-modulated in accordance with the divided image parts. A plurality of mirrors reflect the image light beams and introduce them on...

A projecting apparatus having a first projecting system for projecting an object to be projected to form an intermediate image, and a second projecting system for projecting the intermediate image formed by the first projecting system onto a screen. The first projecting system is adapted to distort the image of the object, and the second projecting system is adapted to correct the distorted image to project an enlarged image analogous to the object onto the screen.

A projector has projecting optical systems which include image formers and projecting lenses for projecting the formed images onto a screen. The optical axes of the projecting lenses are intersected with each other on or very near the surface of the screen. The image formers are arranged such that an image surface of each image former is coincident with the screen in accordance with Scheimpflug's rule.

A projector includes: a light source device that emits a laser beam toward a projected surface; a scanning unit that scans the laser beam emitted from the light source device; a light diffusion member that diffuses the laser beam used for scanning by the scanning unit; and a converging unit that converges the laser beam going out from the light diffusion member on the protected surface.

A projector includes a first housing, a second housing, and a sound insulating member. The first housing is provided with first heat-generating elements used for generating an image, first fans producing cooling airflows towards each one of the first heat-generating elements, and vents via which the cooling airflows heated by the first heat-generating elements are discharged. The second housing encloses the first housing, and has second fans discharging the cooling airflows outside the projector...

An embodiment of an apparatus includes a surface and a projector to project light onto the surface. The embodiment further includes a first lens array to receive the light from a first region of the surface and a second lens array to receive the light from a second region of the surface.

A projector with a light source device; an optical modulator for modulating a light beam irradiated by the light source device; a projection optical device for projecting the light beam modulated by the optical modulator in an enlarged manner; and an exterior casing for housing the light source device, the optical modulator, and the projection optical device, includes: an optical diaphragm disposed on an optical path between the light source device and the optical modulator, the optical diaphrag...

A projector includes a laser beam source that outputs a laser beam and modulates the laser beam in a beam form based on an image signal, a scanning unit that scans the laser beam output by the laser beam source at least in one-dimensional direction, a scan driving unit that drive controls the scanning unit by a first force, a retaining unit that stops and retains the scanning unit at a predetermined position by a second force, and a light shielding unit that shields the laser beam from the scann...

The present invention discloses a projector comprising: a lamp module for receiving therein a lamp as a light source; an enclosure fixing said lamp module therein such that an optical axis of said lamp module is kept in a predetermined direction; two positioning pins provided on said lamp module and inserted into positioning holes made in a vertical direction to said enclosure for controlling movement of said lamp module in a horizontal plane; and a first rib provided on said enclosure as extend...

The invention achieves a reduction in size of a projector by shortening a length of an optical path of an illuminating optical system in a projector using an emitting direction control-type optical modulation device as compared to that of a conventional illuminating optical system, and thus, improves the illumination efficiencies of the illuminating optical system. An illuminating optical system includes a light source, a first lens array having a plurality of first small lenses for dividing lig...
