Description

  The present invention relates to a wearable electronic eyeglass device provided with a display device for projecting image light directly onto a retina through a pupil using Maxwell's view.

  Maxwell's vision is the principle of a pinhole camera, which focuses highly directional image light within the pupil of the eye and directly focuses the image light on the retina without using the focus adjustment function of the lens. Because the projection is deep and the depth of focus is deep, the function of the crystalline lens and cornea is reduced, and even for low vision people who are difficult to see even when wearing glasses, the retina is focused and the image is It looks clear without blur. Japanese Patent Application Laid-Open No. 2004-151561 discloses an “image providing apparatus” that can provide a clear image to a patient with an eye disease using such Maxwell vision.

Further, Non-Patent Document 1 discloses a paper reporting the result of measuring the reading ability of a low vision person using a retinal projection type display using laser scanning. In this non-patent document 1, for a mobile, a display is fixed to the head with a headband, and an image is projected onto the retina by matching this with the position of the pupil of the eye.

Embodiments 1 to 7 of the wearable electronic eyeglass device of the present invention will be described below with reference to the drawings.
(Embodiment 1)
In the first embodiment, a case of a wearable electronic eyeglass device having an alignment mechanism that allows easy alignment of a convergence point of an image and a pupil will be described.

  FIG. 1 is a perspective view showing a configuration example of a main part of a wearable electronic eyeglass device according to Embodiment 1 of the present invention.

  In FIG. 1, the wearable electronic eyeglass device 1 of Embodiment 1 includes an optical unit 2 of an electronic eyeglass main body in which image light with high directivity using Maxwell vision is emitted from an image emitting unit 21 (eyepiece lens 21 a). And an alignment mechanism portion 3 that is mounted on and holds the central portion of the electronic eyeglass body that is the optical unit 2 and that allows the optical unit 2 to be set and fixed three-dimensionally. .

  The optical unit 2 is an optical system that constitutes an image emitting unit 21 that emits image light with high directivity using Maxwell's view in a box-shaped enclosure configured in an L shape or an I shape in plan view. (Not shown), a display device (spatial modulation element; not shown) such as a liquid crystal display device having a display screen provided behind the optical system, and an illumination light source for emitting illumination light to the display device A lighting device (not shown) and a power supply unit (battery; not shown) that can supply power to each unit are provided.

  The display device receives a predetermined signal by inputting image data such as a subject image captured by a video camera or the like, recorded on a recording medium such as a DVD, or obtained via a communication line such as the Internet or an intranet. A signal processing unit (not shown) that performs processing (for example, white balance processing and gamma correction processing), and illumination light from the illumination light source based on image data that has undergone predetermined signal processing by the signal processing unit And a display image forming unit (not shown) displayed on the display screen by (backlight).

  As an example, the display image forming unit includes a spectroscopic optical system that splits light from an illumination light source connected to a power source into R (red), G (green), and B (blue) colors, and the spectroscopic optical system. R (red), G (green), and B (blue) in which each color spectrum (parallel rays) is irradiated as a backlight, and a power line and a video signal line are connected to display a liquid crystal for each color. And a combination optical system for synthesizing and emitting image light of each color from the transmission liquid crystal display device of each color as a color display image. Alternatively, as a display image forming unit, a single transmission type liquid crystal display panel irradiated with an illumination light source (for example, a white LED light source) connected to a power line (illumination power source unit), and R (red), G (green), and A transmissive liquid crystal display panel having a single transmissive counter display panel periodically coated with a B (blue) filter is provided, and color display image light is emitted from the transmissive liquid crystal display panel.

  The image emitting unit 21 condenses the image light emitted from the display screen of the display image forming unit on the pinhole of the pinhole plate with a condensing lens, and has high directivity emitted from the pinhole. After the image light is returned to the parallel light beam by the lens, the parallel light beam is narrowed by the eyepiece lens 21a and converged in the user's pupil.

  An eyepiece 22 that protrudes from the periphery of the eyepiece 21 a of the image emitting portion 21 is provided. The eyepiece 22 is made of a resin material such as silicon rubber or a metal material.

  On the other hand, the alignment mechanism part 3 is a frame member 31 that can be fixed to the housing central part 23 with a first fixing tool (screw or the like) in a state where the housing central part 23 of the optical unit 2 having a quadrangular cross section is inserted. The frame member 31 can be attached to the frame member 31 in a predetermined direction (vertical direction in FIG. 1) so that the position thereof can be freely changed (moved), and can be fixed by a second fixing tool (screw or the like) at the set position. And a belt-like member 32 as a position setting connecting member.

  The frame member 31 is made of a metal such as stainless steel, aluminum or titanium alloy, or an alloy material thereof or a resin material, and is formed into a quadrangular ring shape. The upper surface 31a has screw holes at least at two locations, and the side surface 31b has Also, at least two screw holes are provided. In order to fix the frame member 31 to the central part 23 of the optical unit 2 in the screw hole of the upper surface 31a, a screw 31c having a large outer diameter of the screw head is screwed and attached.

  Here, the cross-sectional shape of the housing central portion 23 of the optical unit 2 is a rectangular shape having a long side and a short side, and the housing central portion 23 is also inserted into the opening shape inside the frame member 31 in accordance with this rectangular shape. A rectangular shape that is slightly larger than the outer shape of the housing central portion 23 is formed as much as possible. In particular, the short side of the rectangular central portion 23 of the cross section has a small gap that can be inserted into the rectangular opening with respect to the frame member 31, and the long side of FIG. In the direction, a gap is provided with respect to the frame member 31 so that the optical unit 2 can be slightly adjusted. Thereby, the optical unit 2 can be moved and adjusted with respect to the frame member 31 in the front-rear direction so that the Maxwell-view exit light convergence point is located in the pupil.

  In addition, since the frame member 31 can be inserted into and removed from the central portion 23 of the optical unit 2, the position of the pupil is also determined in the insertion or extraction direction (left and right direction in FIG. 1; insertion and extraction direction) of the optical unit 2. Movement adjustment can be performed so as to match the exit light convergence point of Maxwell's view. In addition, regarding the vertical movement of the optical unit 2, the upper and lower surfaces of the inner surface of the opening of the frame member 31 are sliding surfaces with respect to the housing central portion 23, and the optical unit 2 includes the frame member 31. However, since the gap is largely movable in the front-rear direction as described above, it can be positioned so as to be rotatable around the vertical axis (rotate in a horizontal plane). That is, the frame member 31 has an optical cross-sectional shape of the quadrangular optical unit 2 inserted into the quadrangular frame, and an insertion / extraction direction in which the optical unit 2 is inserted into / extracted from the frame and a direction perpendicular thereto. Position setting is possible in the rotation direction around two of the three axes in space and the remaining one axis. Thereby, movement adjustment can be performed so that the position of the pupil matches the exit light convergence point in Maxwellian view. In this manner, the optical unit 2 can be moved so that an image can be seen by holding the position of the optical unit 2 by hand within the frame of the frame member 31 that restricts the movement of the optical unit 2 in the vertical direction and the front-back direction. it can.

  When the optical unit 2 is fixed in the frame (inside the opening) of the frame member 31 after the positioning, the two screws 31c having a large outer diameter of the screw head are tightened on the surface of the central part 23 of the housing of the optical unit 2. The optical unit 2 is fixed to the frame member 31 by pushing up the screw tip. In this case, at least the housing central portion 23 of the optical unit 2 needs to be made of a hard material and thick so that the surface can withstand even if it is repeatedly fixed. Good.

  The belt-shaped member 32 is a member that is made of a light metal or a resin material and that holds and fixes the optical unit 2 fixed in the frame of the frame member 31. The strip member 32 and the frame member 31 are coupled by a coupling fixture such as a screw. An elongated hole 32a that is longer than the pitch of the two screw holes provided on the side surface 31b of the frame member 31 by the movement adjustment distance is formed along the longitudinal direction from the end of the belt-shaped member 32. The two screws 32b can be screwed into the two screw holes on the side surface 31b through the holes 32a, respectively, so that they can be connected to each other so as to be movable in the vertical direction (the remaining one axial direction). Accordingly, it is possible to adjust the movement so that the position of the pupil and the exit light convergence point in Maxwell's view are aligned in the vertical direction. After the position adjustment, the belt-like member 32 can be fixed to the frame member 31 by tightening the two screws 32b. The front end side of the belt-like member 32 can be fixed to a hat collar or a spectacle frame which will be described later.

Accordingly, the eye pupil 22 is placed in contact with the eye periphery or eyeglass lens so that the positional relationship between the eyepiece lens 21a and the pupil, that is, the optical unit 2 is held by hand so that the image can be seen. It is possible to position the positional relationship of the image light exit surface of the eyepiece 21a with respect to the vertical direction, the horizontal direction, the front-rear direction, and the rotational direction around the vertical axis (the rotational direction in the horizontal plane). This makes it easy to first find the image emitted from the image light exit surface of the eyepiece 21a from which the image light with high directivity using Maxwell's view is emitted. Thereafter, at least two screws 31c and at least two screws 32b may be tightened to fix a set position where an image can be seen.

  FIG. 6K is a perspective view illustrating a first configuration example of the wearable electronic eyeglass device according to the sixth embodiment of the present invention. Constituent members having the same operational effects as those of the constituent members described above are denoted by the same reference numerals and description thereof is omitted.

  In FIG. 6K, the wearable electronic eyeglass device 1K according to the sixth embodiment is an optical unit 2K of the electronic eyeglass main body in which highly directional image light using Maxwell's view is emitted from an image emitting unit 21 (not shown). And an alignment mechanism portion 3K that is attached to and holds one end portion 23K of the electronic eyeglass main body, which is the optical unit 2K, and that allows the optical unit 2K to be set and fixed three-dimensionally. ing.

  The optical unit 2K has an optical system (not shown) in the same manner as the optical unit 2 described above, in a box-shaped casing configured in a L shape in plan view that is bent from one eye to the side of the face. And a display device (not shown), an illumination device (not shown), and a power supply unit (battery; not shown). In this case, the difference from the first to fifth embodiments is the outer shape of the housing, and the front of the eye that does not see the image through the optical unit 2K is not obstructed by the optical unit 2K. Is to see.

  The alignment mechanism 3K is inserted into (or loosely fitted) by the first fixing tool (such as a screw or a pin member) in the state where the end portion 23K on the image output side of the housing of the optical unit 2K having a quadrangular cross section is inserted. A frame member 31K that can be fixed to the housing end portion 23K, and a frame member 31K that can be attached to the frame member 31K in a predetermined direction (vertical direction in FIG. 6K) so that the position can be freely changed (moved). It has a belt-like member 32K as a position setting connecting member that can be fixed by a fixing tool (screw or pin member).

  The frame member 31K is made of a metal such as stainless steel, aluminum or titanium alloy, or an alloy material thereof (light alloy material) or a resin material, and is formed into a quadrangular ring shape. (Fixing tool) is provided, and at least two screw holes (one of the second fixing tools) are also provided on the side surface 31Kb. In order to fix the frame member 31K to the housing end portion 23K of the optical unit 2K, a screw (not shown) having a large outer shape of the screw head is screwed into the screw hole of the lower surface 31Ka.
