no. 1 approach

[0035] figure 1 is a partial configuration diagram schematically illustrating main components of the glasses-type image display device according to the first embodiment of the present invention. In this figure, the eyeball 2 of the right eye of a viewer when he / she wears the glasses-type image display device 1 is also shown. The glasses-type image display device 1 has a configuration in which an image output unit 5 and a plane mirror 6 constituting a reflection unit are added to glasses mainly composed of a spectacle lens 3 and a spectacle frame 4 .

[0036] The spectacle frame 4 includes endpieces 7 fixed to the spectacle lenses 3 or the frame of the spectacle lenses 3 and positioned at both ends on the front surface of the spectacle, the spectacle legs 9 passing through the hinges, and the hinges 8. 8 is foldably connected with Zhuangtou 7. The position of the glasses-type image display device 1 can be fixed relative to the eyeballs 2 of the observer by hanging the temples...

no. 2 approach

[0050] Figure 7 is a diagram illustrating the configuration and usage state of the glasses-type image display device according to the second embodiment of the present invention. In addition to the schematic configuration of the glasses-type image display device 1, Figure 7 The optical path of the image light output from the image output unit 5 and reaching the pupil 11 of the eyeball 2 is also shown.

[0051] Such as Figure 7 shown, except figure 1 In addition to the configuration of the glasses-type image display device 1 , the glasses-type image display device according to the present embodiment further includes a deflection prism 21 connected to the temple 9 and a projection lens 22 connected to an output surface of the deflection prism 21 . The deflecting prism 21 and the projection lens 22 may be integrally molded. In addition, the device is configured so that the image light output from the image output unit 5 along the temple 9 is incident on the incident surface...

no. 3 approach

[0056] Figure 9 is a diagram illustrating the configuration and usage state of the glasses-type image display device according to the third embodiment of the present invention. In this embodiment, image output units 5l and 5r, deflecting prisms 21l and 21r, projection lenses 22l and 22r, and plane mirrors 6l and 6r are provided for the left eyeball 2l and the right eyeball 2r, respectively. In addition to the plane mirrors 6l and 6r that are respectively arranged in front of each eyeball, a mirror is also provided for the left eye. figure 1 Various configurations of the glasses-type image display device for the right eye.

[0057] In this case, in the state where the viewer faces the front, the electronic image output from the image output unit 5l on the left and the electronic image output from the image output unit 5r on the right are superimposed, and in the field of view and in the The front of the viewer is displayed, therefore, in addition to the effect of the second ...

Abstract

A spectacles-type image display device comprises an image output unit for outputting image light of images to be displayed and a reflection unit disposed in a field of view of at least one eyeball of a viewer. The reflection unit is adapted to reflect the image light output from the image output unit toward the eyeball of the viewer so that the viewer can see virtual images of the images. The minimum value of a width of a projection cross-section of the reflection unit in an output direction of the image light to the eyeball is smaller than a dark-adapted pupil diameter of human and is larger than a light-adapted pupil diameter of human. A plane mirror 6 is in the shape of vertically-long rectangular, and the horizontal width of the projection cross-section in the output direction of the image light to the eyeball is from 1 mm as the light-adapted pupil diameter to 7 mm as dark-adapted pupil diameter.

Description

technical field [0001] The present invention relates to a glasses-type image display device. Background technique [0002] Generally, a device including, for example, an image output unit held on a temple side of glasses and an eyepiece optical unit held adjacent to a lens of the glasses is proposed as a glasses-type image display device. Such a glasses-type image display device is configured such that image light of an electronic image to be displayed output from an image output unit is incident on a viewer's eyeball through an eyepiece optical unit, whereby the viewer can see the image. In such a glasses-type image display device, an electronic image and a background image through the glasses lens are usually superimposed and displayed on the eyeball, so the viewer can see the electronic image as a translucent image in his / her field of view (ie, "see-through image"). [0003] As a method for realizing a see-through image, known is a device using a half mirror and a lens ...
