    摘要: An optical transmitter and receiver module which can enhance a coupling comprises a light source emitting the first light, a light-receiving section receiving the second light, a diffraction device changing the direction of travel of at least one of the first light and the second light, a first lens which condenses the first light, outgoing from the light source and entering through the medium of the diffraction device, onto a light input/output face of the optical fiber and condenses the second light outgoing from the optical fiber onto the light-receiving section through the medium of the diffraction device, and a second lens which inhibits a beam of the first light outgoing from the light source from diverging and allows it to enter the first lens through the medium of the diffraction device.

    摘要: In an image display apparatus including a delta-array display device and pixel position transition means for repeatedly shifting the respective pixel positions of the display device to each of positions at four points, the pixel shifted positions at the four points are: a first pixel position serving as standard; a second pixel position shifted with respect to the first, standard pixel position horizontally approximately by ½ of horizontal pixel pitch; a third pixel position shifted horizontally approximately by ¾ or ¼ of horizontal pixel pitch and vertically approximately by ½ of vertical pixel pitch; and a fourth pixel position shifted horizontally approximately by ¼ or ¾ of horizontal pixel pitch and vertically approximately by ½ of vertical pixel pitch. The image display apparatus is thereby provided as having an improved, doubled resolution in both vertical and horizontal directions by applying the 4-point pixel shift system to the delta-array display device.

    摘要: An image display apparatus including a liquid crystal display panel (LCD) constituting an image display plane composed of a plurality of pixels arranged with a pixel pitch, a LCD driver circuit which receives an input image signal S1 and displays an image on a substantially whole image display plane of the LCD as well as a part of the image on a selected region C of the image display plane by selectively shifting image display positions of the image with respect to inherent positions on said image display plane in a given direction by an integer multiple or an inverse of an integer multiple of the pixel pitch of the LCD, and a pixel shift driver circuit which effectively and selectively shifts, in synchronism with the operation of said LCD driver circuit, said image display plane in a direction opposite to said given direction in which said image display position shifting is carried out. Even if the LCD has a larger number of scanning lines or the pixel shift operation is performed by a larger number of times, the resolution can be effectively improved.

    摘要: An image display apparatus for use in head-mounted image display apparatus is disclosed. The apparatus comprises an image display element having a plurality of pixels arrayed in matrix, for displaying images by scanning these pixels with image signals; a pixel shifting means provided so as to divide these image display elements into a plurality of regions in a direction orthogonal to the scanning direction of the image signal, for selectively shifting viewing positions of the displayed images in respective regions; and a control means for controlling shifting operation at the viewing positions of the displayed images in corresponding regions of the pixel shifting means, in synchronism with the scanning of the image display elements.
