Abstract: Disclosed are an imaging device and a display device which both have a simple structure without any need of an image conversion. The imaging device includes a lens component group including multiple lens component systems, each of which focuses incident light from the object, thereby creating a non-inverted image of the object, the lens component systems being arranged in an array form and on the same level, and an image capturing mechanism for picking up the created image. In addition, each of the lens component systems includes an afocal optical system and an image-forming system. The afocal optical system includes at least one optical element for inverting an externally incident light ray relative to its optical axis and outputting the light ray. The optical element has uniform refractive index. The image-forming system includes at least one optical element having uniform refractive index throughout its interior.

Abstract: To provide an optical assembly capable of enhancing black level display while preventing deterioration of a WV film, and a projector assembled therewith, optical compensation elements are disposed before and after liquid crystal light valves, so that an unintended phase difference generated on the incident and emission sides of the liquid crystal light valves for individual colors is eliminated by adjusting the rotational positions of the optical compensation elements, thus enabling an enhancement in the contrast of a color image displayed on a transmission screen member.

Abstract: In order to provide a rear projector capable of facilitating position adjustment of an image displayed on a screen and optimizing dispersion of the aspect ratio of the projected image caused by tolerance of components by adjusting the position of the image, a support member (200) is provided with a lateral position adjuster (202) as a planar position adjusting mechanism attached on a support plate of an interior unit in an opposing manner, an inclination adjuster (203) as an inclination position adjusting mechanism vertically provided on the lateral position adjuster (202), and a rotary position adjuster (204) as a rotary position adjusting mechanism attached to the inclination adjuster (203) slanted downward toward rear side.

Abstract: A three-dimensional image optical system including at least an elementary image optical subsystem constructed with plural afocal optical elements which include the first and the second optical components, wherein the plural afocal optical elements are aligned in a planar arrangement. The variety of the focal length to satisfy the afocal property is realized with the combination of the first optical components and the second optical components, that results in to provide the flexibility of the depth magnification, by which a remote observation is possible.

Abstract: A rear projector has a lower cabinet disposing an image generator and an upper cabinet for a screen body to be mounted, two woofer boxes being mounted on the front side of the lower cabinet and high-pitched sound speaker boxes being respectively mounted on the right and left lateral sides of the upper cabinet, so that, since the woofer box is disposed in the lower cabinet, vibration is not easily transferred to a screen body on the upper cabinet and a reflection mirror inside the upper cabinet, thus avoiding flicker of the image on the screen body even when great volume of sound is outputted by the woofer box.
