PROBLEM TO BE SOLVED: To improve an image display apparatus of the type in which the display is attached to a pair of glasses and used so that it can be attached to a pair of glasses of any structure. SOLUTION: The image display apparatus 3 builds a liquid crystal display and a magnifying lens in itself, and a user sees an image light from the display through the magnifying lens, thereby enabling seeing an image. The image display apparatus 3 is provided with a sucker 160 on its back surface, and can be attached to smooth front surfaces of the lenses of glasses provided on the glasses by the sucker 160.

PROBLEM TO BE SOLVED: To enable a user to easily view an image on a head-mounted type image display apparatus. SOLUTION: The image display apparatus 100 includes a glasses-like main body 10. The main body 10 is mounted on user's head. A display apparatus 20 positioned in front of user's left eye and a shielding plate 30 positioned in front of user's right eye when the main body 10 is mounted on the user's head are arranged in the main body 10. The display apparatus 20 is prepared for forming an image from the built-in liquid crystal display in his/her left eye and letting the user view the image through his/her left eye. The display apparatus 20 and the shielding plate 30 are interchangeable. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide an imaging tool by which the same image pickup as the one by a general purpose video camera and magnification imaging at high magnification like the one by a "video microscope" can be easily properly chosen according to need while making the effective use of easy magnification change by a zoom function. SOLUTION: Structure where the magnification imaging adapter 2 having an auxiliary lens 16 is combined with an imaging tool body 1 incorporating a camera unit having the zoom function is obtained, so that the image pickup by the imaging tool body while the auxiliary lens of the magnification imaging adapter is made to come off from the incident path of image light to the camera unit and the magnification image pickup while the auxiliary lens is positioned in the incident path of the image light to the camera unit are selectively performed, for example, by attaching and detaching the magnification imaging adapter to/from the imaging tool body.

Abstract:
PROBLEM TO BE SOLVED: To provide a novel light transmitting resin material applicable to a lens. SOLUTION: A basic acrylic resin material 10 having a projected part 12 in the middle is pressed in the direction of the height of the projected part by a press member 20 having a plane contact surface 21 to obtain a plate-shaped light transmitting resin material in which the values of resin density are different from each other of the parts. The light transmitting resin material has a density distribution to maximize the part of the center of the projected part 12 to have a refractive index distribution to maximize the part. The light transmitting resin material, in spite of its plate shape, has optical characteristics similar to those of a lens. COPYRIGHT: (C)2003,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a rod lens having ≥30 cm of one pitch which can be particularly suitably used as an image guide for medical use. SOLUTION: The rod lens is manufactured by filling a cylindrical clad made of a transparent resin with a solution containing monomers of the resin constituting the clad and a refractive index controlling substance and polymerizing the monomers while dissolving the resin constituting the clad wall into the monomers and while concentrically and successively moving a gel layer containing the refractive index controlling substance from the wall face of the clad to the center. The rod lens ≥30 cm of one pitch (L 1pitch ) expressed by formula (I). In formula (I), r c represents the radius of the transmission path of light, n 0 represents the refractive index (nD 20 ) at the center of the optical transmission line and Δn is the difference in the refractive index between the center of the optical transmission line and the clad.

PROBLEM TO BE SOLVED: To provide a diagnostic system to enable patient to undergo simple diagnosis or cure at a place other than a hospital anytime without difficulty. SOLUTION: This system comprises a terminal T connected by a network N and a server S. A user takes an image of a prescribed site on a human body by an imaging device C connected to the terminal T and the taken image is sent to the server S via the network. The server S generates diagnostic data from the sent image data based on the image data of the area corresponding to the skin of the user. COPYRIGHT: (C)2003,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a large-sized optical device that can be efficiently driven by a low voltage with a simple structure. SOLUTION: This liquid crystal layer 31 that is stored between a transparent first electrode 21 and a transparent second electrode 22 and orients liquid crystal molecules unidirectionally. A transparent medium 41 is arranged between the liquid crystal layer and at least one electrode of the first electrode 21 and the second electrode 22, the impedance of the transparent medium forms distribution in a surface, and effective refractive index distribution generated by continuous or step-like variation in voltage applied to the liquid crystal layer is used.

PROBLEM TO BE SOLVED: To provide a head-mounted display for endoscopic surgery which is suitable for use in an endoscopic surgery. SOLUTION: The HMD3 includes nose pads 311 which abut on the nasal bridge of a user, a post 312 which extends upward from the nose pads 311 to the front of the forehead of the user and a fixing member 315 which is attached to the top end of the post 312 backward and has a U-shaped or C-shaped cross section. A display 32 for showing images to the user is attached to the front of the top end of the post 312 is suspended before the eyes of the user and can be flipped up. Both the post 312 and the fixing member 315 hardly come in sight of the user even when the display 32 is in a position where the user can see images. When the display 32 is at an upper position, the user can see the external world with a broader range of view. COPYRIGHT: (C)2010,JPO&INPIT
