    摘要: A visual display apparatus, for example, a head-mounted display apparatus, which enables an image to be observed at a wide field angle and high resolution. The apparatus includes a pair of two-dimensional display devices (4 and 5) disposed with their display surfaces facing each other, and two half-mirrors (6 and 7) which are paired with the display devices (4 and 5) and combined to each other in the shape of a V. The apparatus further includes a concave mirror (8) having a center axis coincident with the center axis of the half-mirrors (6 and 7) combined in a V shape. The two-dimensional display devices (4 and 5) are adapted to display images (11 and 10) each including an overlap region (9) and having an area wider than one half of the image for observation. The images (11 and 10) are combined together into one continuous image by the two half-mirrors (6 and 7) combined in a V shape.

    摘要: A head-mounted image display apparatus having an exit pupil that is enlarged without causing an increase in the size of a relay optical system or a reduction in the size of a projected image. The head-mounted image display apparatus has an image display device (1) having a display surface for displaying an image, a relay optical system (2) for transmitting the image displayed on the display surface of the image display device (1) to form an image of the display surface, and an ocular optical system (4) for projecting the image transmitted by the relay optical system inside an observer's eyeball as an enlarged image. A numerical aperture (NA) enlarging element is disposed at a position conjugated with the display surface with respect to the relay optical system (2). Thus, pupil alignment is facilitated without causing an increase in the size of the relay optical system (2) or a reduction in the size of the projected image. Also, provided as a technique whereby field curvature of the ocular optical system is corrected to provide a flat image for observation.

    摘要: A display apparatus of the type that is fitted to the user's head or face, and having a higher resolution in a first region of the display than that of the remaining area of the display, without increasing the size of the display. As an example, an image of the characters "ABC", for example, are generated or received. However, it might be desired that the center character "B", for example, be displayed at a higher resolution than that of the characters "A C". To accomplish this, the original image "ABC" is divided into an image of "A C" and an image of "B". Then, the image of "B" is electrically distorted and formed on a screen such that the image of "B" is larger in size than the image of "A C". An ocular optical system including an optical element effects a second distortion of the image to correct the electrically created distortion. This ocular optical system enlarges the image such that the image of "A C", which has been displayed relatively small, is enlarged, and projects the image of "B", which has been displayed relatively large, through a lens having a correspondingly lower magnification. Then, the image of "B" is superimposed on the image of "A C" so that the image of "A C" and "B" are displayed at the same size, but with "B" being represented by more pixels or pixels which are finer than those representing "A C".

A refracting optical element (4) is disposed at the pupil plane (E) or image plane (I) side of the partial optical system (10) with an air spacing provided therebetween. Alternatively, the refracting optical element (4) may be cemented to the partial optical system (10).

    摘要: A small-sized, lightweight and inexpensive visual display apparatus which enables observation of a full-color image at a wide field angle, which is clear and flat as far as the edges thereof, without using a costly element such as a polarizing element. The visual display apparatus has an image display device (4), and an ocular optical system for projecting an image formed by the image display device (4) and for leading the projected image to an observer's eyeball. The image display device (4) has a louver (10) for limiting the viewing angle. The ocular optical system has two semitransparent surfaces (2 and 3). The second semitransparent surface (3) is a curved surface which is concave toward the observer's eyeball side, so that light rays emanating from the image display device (4) first pass through the second semitransparent curved surface (3), and are reflected by the first semitransparent surface (2). The reflected light rays are further reflected by the second semitransparent curved surface (3), and then pass through the first semitransparent surface (2) to enter the observer's eyeball. Further, the two semitransparent surfaces (2 and 3) are disposed such that at least the first semitransparent surface (2) is decentered with respect to the observer's visual axis directed to see the center of the projected image.

    摘要: An optical element is made of a transparent medium that is rotationally symmetric relative to the central axis with a refractive index greater than 1. The transparent medium has a first transmissive surface at the outermost periphery relative to the central axis, a first reflective surface at the side of the central axis relative to the first transmissive surface, a second reflective surface at the side opposite to the image plane relative to the first reflective surface and a second transmissive surface at the side of the image plane relative to the second reflective surface. The flux of light enters and proceeds through the transparent medium via the first transmissive surface, the first reflective surface, the second reflective surface and the second transmissive surface to form an optical path. The optical path is formed only at a side relative to the central axis.
