Abstract

PROBLEM TO BE SOLVED: To permit natural stereoscopic vision by preventing a visual field fight. SOLUTION: The light emitted from a spot light source 20 for the right eyes is modulated by a transparent type liquid crystal panel 22, by which a parallax image 50 corresponding to the right eye is formed. The parallax image 50 corresponding to the right eye is made incident on the crystalline lens 10a through an ocular lens 24 from an observation hole of a diameter D3 smaller than the diameter D1 of the pupil 14 of the right eye 10 and an image 60 is formed on the retina 10c. The parallax image 52 corresponding to the left eye is similarly made incident on the crystalline lens 12a from the observation hole of a diameter D4 smaller than the diameter D2 of the pupil 16a of the left eye 12 and an image 62 is formed on the retina 12c. Virtual images 70 and 72 are observed as the parallax images by an observer and the stereoscopic images having a thickness are observed before and behind these parallax images. At this time, the incident aperture diameter of the images on the pupils of both eyes are converged at all times regardless of the sizes of the pupils and, therefore, the depths of focus of the crystalline lenses of both eyes are increased and even if the crystalline lenses are focused at the stereoscopic images parting from a parallax image display surface, the parallax images remain focused and, therefore, the observation of the natural stereoscopic images having the lessened visual field fight is made possible.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereoscopic image display apparatus for displaying a stereoscopic image based on a parallax image corresponding to the right eye and a parallax image corresponding to the left eye, and more particularly to a stereoscopic image accompanying focus adjustment of a crystalline lens, that is, natural vision. Related to the display of a stereoscopic image close to.

[0002]

2. Description of the Related Art When an observer views a stereoscopic image in the natural world, both eyes capture a parallax image from different directions toward a point of interest of the stereoscopic object to be observed. In conjunction with this, the lens of the eye is also automatically adjusted to the position of the point of interest.

On the other hand, most of the stereoscopic image display devices known to date display parallax images corresponding to the left and right eyes on a display plane at a fixed position, and have a thickness before and after the display position. It produces images with a three-dimensional effect (three-dimensional images). In this case, the parallax image on the display plane is blurred when the lens of the observer's eye is adjusted to focus on a point of interest away from the display plane. Therefore, in the crystalline lens of the observer's eye, visual field conflict occurs in which the focus is adjusted not on the point of interest but on the display plane, and only a stereoscopic image having a psychological load different from natural stereoscopic vision is obtained.

On the other hand, the following is known as a stereoscopic image display device capable of adjusting a crystalline lens of an observer's eye in accordance with a displayed three-dimensional object.

(1) Depth sampling method Examples of this type of display include a graphic device for producing a three-dimensional image, Nikkei Electronics, 198
There is a varifocal mirror method as described in “1.12.7”. This means that the reflecting mirror is vibrated by an electric signal, and tomographic images at different positions synchronized with the CRT are displayed on the CRT.
It is to be displayed on the screen. According to this method, a plurality of tomographic images reflected by the mirror can be observed as a three-dimensional image by utilizing the afterimage phenomenon of the eye.

[0006] However, this method can be applied only to special uses since the entire image can be seen through.

(2) Electronic holography As this type of display, “SABenton, et, al .:
Electronic displaysystem for computational hologra
phy, Proc. SPIE, 1212, Practical Holography IV, pp. 1212-
1220 (1990). In this technique, image information when an object is moved is calculated using a high-speed supercomputer, and this is used as a video signal to drive an ultrasonic light modulator (AOM). This AOM
Is a one-dimensional light wavefront modulation device that irradiates a laser beam and diffracts the light to create a horizontal image signal, and in the vertical direction, scans while driving a galvanometer mirror to synthesize and display the image . At this time, the polygon mirror is reversely rotated at a constant speed in order to prevent the light wavefront from moving in the lateral direction when the ultrasonic wave travels in the AOM. Thereafter, the viewing area of the image is enlarged through a reduction lens. With this method, a full-color moving image can be displayed at present.

[0008] However, this method requires too much information and requires an expensive large-scale computer.
Moreover, there is a problem that it can be applied only to the display of a CG object.

(3) Movement of display surface An example of this display is disclosed in JP-A-8-22360.
There is one disclosed in Japanese Patent Application Laid-Open Publication No. 9-No. In this method, an image is displayed while detecting a viewpoint of an observer and mechanically moving a display surface to a position matching the viewpoint position by a driving unit (motor).

This method has been developed as a head mounted display (HMD), but has a problem that the overhead mounting portion is large and heavy because a mechanical moving mechanism is required.

Therefore, an object of the present invention is to solve the conventional problems described above and to provide a simple structure.
An object of the present invention is to provide a stereoscopic image display device that enables natural stereoscopic viewing.

[0012]

According to one aspect of the present invention, a corresponding parallax image is caused to enter the right and left eyes of an observer,
In a stereoscopic display device that displays a stereoscopic image, a light source for the right eye and a light source for the left eye having at least one small light emitting unit, and each of the light sources for the right eye and the light source for the left eye from at least one small light emitting unit. At least one light-collecting optical means for causing light to be incident on an observation hole smaller than a pupil of the right eye and the left eye of the observer; the light source for the right eye, the light source for the left eye, and the at least one light-collecting optical means Placed between
At least one optical modulating unit that modulates light from at least one small light emitting unit of the light source for the right eye and the light source for the left eye, respectively, to form a parallax image for the right eye and a parallax image for the left eye, It is characterized by having.

According to the present invention, when observing a stereoscopic image based on a binocular parallax image formed by at least one optical modulating means, by using at least one condensing optical means, the pupil of both eyes can be observed. Is always narrowed regardless of the size of the pupil. In this way, the depth of focus of the lens of both eyes will be deep, and even if the lens is focused on a stereoscopic image that is away from the parallax image display surface, the parallax image will not be blurred, so it is possible to observe natural stereoscopic images with little visual field conflict Become.

Here, the at least one optical modulating means includes a right-eye spatial light modulating means for modulating light from the right-eye light source, and a left-eye spatial light modulating means for modulating light from the left-eye light source. Light modulating means, which can be a two-dimensional image display device such as a liquid crystal panel. Further, the at least one light-collecting optical unit is a right-eye light-collecting optical unit that collects light from a small light emitting unit of the right-eye light source into an observation hole smaller than a pupil at the right-eye observation position, A light condensing optical unit for the left eye that condenses light from the small light emitting unit of the light source for the left eye into an observation hole smaller than the pupil at the left eye observation position can be provided. These are lenses, concave mirrors or HOEs
It can be. The light source for the right eye and the left eye is preferably a small light emitting unit such as a point light source, for example, and one or a plurality of pixels of the two-dimensional display image device can be made to emit one small light emitting unit.

Here, the light source for the right eye and the light source for the left eye may each have a plurality of small light emitting units which emit light in a time-division manner. At this time, the light-collecting optical unit emits light from the small light-emitting units of each of the right-eye light sources that emit light in a time-sharing manner, and light from each of the small light-emitting units of the left-eye light source. Light is focused on each of the observation holes at the observation positions of the right eye and the left eye of the observer. In addition, the optical modulation unit, according to the time-division light emission of the small light emitting unit of each of the light source for the right eye and the light source for the left eye, to the observation hole of each of the right eye and the left eye of the observer The corresponding parallax image for the right eye and the parallax image for the left eye are formed.

In this case, the optical modulating means converts a plurality of types of right-eye and left-eye parallax images into a conventional one-frame time (for example, 1/100) based on image information observed from a plurality of different angles.
Within 30 seconds), the display is performed one by one at high speed, and the small light emitting portions are sequentially lit one by one, so that different parallaxes are obtained in each small area (observation hole) of the binocular pupil of the observer who observes through the observation hole. The image is incident. In this case, in each region, the depth of focus of the crystalline lens of both eyes is increased, and the parallax image is not blurred even when the stereoscopic image separated from the parallax image display surface is focused. Therefore, in the observation from the plurality of small regions, only the portion where the lens is out of focus is blurred, so that a more natural three-dimensional image with less field conflict can be observed.

In the present invention, there is provided sensing means for sensing pupil position information of each of the right eye and the left eye of the observer, and the right eye light source and the left eye The light emitting position of each of the small light emitting units of the ophthalmic light source can be changed.

In this way, the stereoscopic view with little visual field conflict is possible in the same manner as the above-mentioned operation, and the light source is moved so that the position of the observation hole moves following the position of the pupil of the observer even if the position of the pupil of the observer moves. Since the light emitting position of the small light emitting unit is changed, the parallax image can always be made to enter the observation hole smaller than the pupil, and the viewing angle is enlarged.

Here, the pupil position information sensing means comprises:
It can have an infrared light source, an infrared filter, and a camera. In this case, irradiate the observer's eyes with an infrared light source,
The corneal reflection image may be sensed by a camera or a PSD and displayed on a two-dimensional image display device serving as a light source.
Alternatively, the sensed information may be processed by a computer or the like, and the result may be displayed on a two-dimensional image display device using the light source. Further, it is preferable that the relative positions of the pupil and the incident area (observation hole) of the parallax images on the pupil before and after tracking are substantially the same.

According to another aspect of the present invention, there is provided a stereoscopic display apparatus for displaying a stereoscopic image by causing a corresponding parallax image to enter the right eye and the left eye of an observer. Parallax image display means for displaying a parallax image on the display surface, imaging optical means for forming the right-eye corresponding parallax image and the left-eye corresponding parallax image, respectively, and the formed right-eye corresponding parallax image and An eyepiece optical unit that allows the observer to observe the parallax image corresponding to the left eye as a virtual image, and an entrance limiter for the right eye and the left eye that is disposed between the eyepiece optical unit and the parallax image display unit, and has an opening, respectively. And the light emitted from the opening of each of the right-eye and left-eye incidence limiting means is directed to the right of the observer by at least one of the eyepiece optical means and the imaging optical means. Observations smaller than the pupil of each eye and left eye Characterized in that it is focused on.

According to the present invention, when observing a stereoscopic image based on the binocular parallax image displayed by the parallax image display means, the light emitted from each opening of the right-eye and left-eye incidence limiting means. In, the entrance aperture of the image to the pupils of both eyes is always narrowed regardless of the size of the pupils. In this way, the depth of focus of the lens of both eyes will be deep, and even if the lens is focused on a stereoscopic image that is away from the parallax image display surface, the parallax image will not be blurred, so it is possible to observe natural stereoscopic images with little visual field conflict Become.

Here, the parallax image display means can include means for displaying a parallax image corresponding to the right eye, and means for displaying a parallax image corresponding to the left eye.
It can be a two-dimensional display device such as T.

Here, each of the right-eye and left-eye incidence limiting means can be an optical shutter array having a plurality of optical shutters that are opened and driven in a time-division manner.

[0024] At this time, the parallax image display means, based on image information respectively photographed from a plurality of different angles,
A plurality of types of the right-eye corresponding parallax image and the left-eye corresponding parallax image are displayed within one frame time (for example, 1/30 second) of the related art, and a plurality of optical shutters of the right-eye and left-eye optical shutter arrays are provided. By sequentially opening one by one, a plurality of observation holes can be formed in the pupil of the observer, and different parallax images can be respectively incident. By doing so, the viewing angle is enlarged.

Also in this case, there is provided sensing means for sensing pupil position information of each of the right eye and the left eye,
The open positions of the right-eye and left-eye optical shutter arrays can be changed based on the sensed pupil position.

Thus, even if the position of the pupil moves, a stereoscopic view following the position of the pupil can be obtained. Similarly, the viewing angle is expanded.

In the present invention, the observation hole has a diameter of 0.5 mm.
It is preferable that the shape be a circle having a size of up to 1.5 mm or an area corresponding to the circle.

The smaller the entrance aperture of the parallax image is, the smaller the blur of the stereoscopic image is. However, if the entrance aperture is too narrow, the image becomes dark. Therefore, it is more preferable to set the entrance aperture in the above range.

According to still another aspect of the present invention, in a stereoscopic display apparatus for displaying a stereoscopic image by causing a corresponding parallax image to enter the right and left eyes of an observer, the parallax image corresponding to the right eye and the left eye Parallax image display means for displaying the parallax images on the display surface with different polarizations, right-eye and left-eye observation means attached to the eyeball in contact with the cornea of the right and left eyes of the observer, And each of the right-eye and left-eye observation means,
It has a polarized light passing part smaller than each pupil of the right eye or the left eye of the observer, and a light shielding part larger than the pupil around the polarized light passing part.

According to the present invention, when observing a stereoscopic image based on a binocular parallax image, the pupils of both eyes are observed by the right-eye and left-eye observing means directly attached to both eyes such as contact lenses. Aperture is always narrowed regardless of the size of the pupil. In this way, the depth of focus of the lens of both eyes will be deep, and even if the lens is focused on a stereoscopic image that is away from the parallax image display surface, the parallax image will not be blurred, so it is possible to observe natural stereoscopic images with little visual field conflict Become.

For the same reason as described above, the polarized light passing portion is preferably a circle having a diameter of 0.5 mm to 1.5 mm or a shape having an area corresponding to the circle.

The polarized light passing section may have a lens function.
With the addition of the lens function, even a person with poor visual acuity can make a stereoscopic view using the above device.

In each of the above-mentioned inventions, it is preferable that the parallax image corresponding to the right eye and the parallax image corresponding to the left eye are captured by a camera having a pinhole lens.

Each parallax image photographed by using a camera with a pinhole lens becomes an image having a large depth of focus. When observing a stereoscopic image by the stereoscopic image display of the present invention, the lens is transformed into a stereoscopic image separated from the parallax image display surface. Since the parallax image is not blurred even if the focus is adjusted, natural stereoscopic view with little visual field conflict is possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) FIG. 1 is a schematic explanatory view showing a first embodiment of the present invention. FIG.
1 illustrates a stereoscopic image display device for displaying a right-eye corresponding parallax image and a left-eye corresponding parallax image to the observer's right eye 10 and left eye 12, respectively.

The stereoscopic image display device shown in FIG.
It is configured as an MD (HEAD MOUNT DISPLAY) and is attached to the observer's head.

In FIG. 1, in order to display a parallax image corresponding to the right eye to the right eye 10, a point light source 20 for the right eye, an optical modulation means for the right eye, for example, a transmission type liquid crystal panel 22, and a condensing optical system for the right eye. For example, an eyepiece 24 is provided. Similarly, left eye 1
2, a left-eye point light source 3
0, optical modulation means for the left eye, for example, transmissive liquid crystal panel 32
And a condensing optical unit for the left eye, for example, an eyepiece 34.

The point light sources 20 and 30 for the right and left eyes can be composed of a light bulb 40, a light shielding plate 44 having a pinhole 42, and a reflecting mirror 46, respectively, as shown in FIG. Alternatively, as shown in FIG. 3, a two-dimensional image display device 110 in which some pixels are illuminated may be used.

The transmissive liquid crystal panels 22 and 32 use point light sources 20 and 30 for the right and left eyes as backlights, respectively.
It is used as a light valve for forming the right-eye corresponding parallax image 50 and the left-eye corresponding parallax image 52. Instead of the transmissive liquid crystal panels 22 and 32, other optical modulation means such as a reflective liquid crystal panel can be used.

Here, as shown in FIG.
The distance from (30) to the eyepiece 24 (34) is fa
s, the distance between the eyepiece 24 (34) and the crystalline lens 10a (12a) of the observer's eye at the observation position is fbs, and the unique focal length Fs of the eyepiece 24 (34) is 1 / Fs. It is preferable that = 1 / fas + 1 / fbs.

The light from the point light source 20 (30) is
a (12a), the lens 11a
This is because the depth of focus can be increased by reducing the aperture of the image incident on (12a).

The parallax image 50 for the right eye and the parallax image 52 for the left eye are incident on the right eye 10 and the left eye 12 via the eyepieces 24 and 34. At this time, in the first embodiment, since the light source 20 for the right eye and the eyepiece 24 are used, the parallax image 50 corresponding to the right eye is the lens 10a of the right eye 10.
Are incident from an area (observation hole) D3 smaller than the diameter D1 of the area (pupil 14) where the aperture opens. Similarly, the parallax image 52 corresponding to the left eye is incident from an area (observation hole) D4 smaller than the diameter D2 of the area (pupil 16) of the left eye 12 where the crystalline lens 12a is open, and the retinas of the right eye 10 and the left eye 12 are formed. 10c, 12c
The images are formed as images 60 and 62 thereon.

At this time, as shown in FIG. 1, for the observer, the right-eye corresponding parallax images 50 and the left-eye corresponding parallax images 52 obtained by the transmissive liquid crystal panels 22 and 32 are enlarged as virtual images 70 and 72. To be observed. And this virtual image 7
When observing 0 and 72, a stereoscopic image is perceived because a phenomenon of binocular parallax occurs.

Here, the sizes (pupil diameters) D1 and D2 of the pupils 14 and 16 are changed by the functions of the irises 10b and 12b of the right eye 10 and the left eye 12, respectively.
Although there are individual differences, the diameter is about 3 mm in bright cases and about 5 mm in dark cases.

In this embodiment, regardless of the pupil diameters D 1 and D 2, the diameter D of the region where the right-eye corresponding parallax image 50 and the left-eye corresponding parallax image 52 enter the pupils 14 and 16.
3, D4 is smaller than 3 mm in diameter when the pupil is bright.
The diameters D3 and D4 at the time of image incidence are preferably as small as possible from the viewpoint of reducing the blur of the stereoscopic image, and are preferably 1.5 mm or less. In addition, the smaller the diameters D3 and D4, the more the amount of light becomes insufficient, resulting in a dark image. Therefore, it is more preferable to set the diameter to a range of 0.5 mm to 1.5 mm. The shape at the time of incidence of the image is not limited to a circle, but may be any shape as long as it is smaller than the pupil diameter.

The reason why a natural stereoscopic view can be obtained by reducing the apertures of the pupils 14 and 16 will be described.

FIG. 30 shows an image formed on the retina when the aperture of the image incident on the pupil is not limited as in the prior art.
FIG. 31 shows an image formed on the retina in the case of the present embodiment.

In the case of FIG. 30, the focus of both eyes is set to the object 90.
When set to 0, the image of the object 902 formed on the retinas 10c and 12c is blurred, whereas in the case of FIG.
Even if the eyes are focused on the object 900, the image of the object 902 formed on the retinas 10c and 12c is hardly blurred.

This corresponds to the objects 900 and 902 shown in FIG.
The spread angles θ1 and θ2 of the objects 900 and 9 shown in FIG.
02 is larger than the divergence angles θ3 and θ4. In other words, when the stereoscopic image with a larger divergence angle is observed, when the back (or front) point is focused on both eyes, the front (or back) point is observed as being blurred. Conversely, when the divergence angle is small as in the present embodiment, when observing a thick stereoscopic image, even if both eyes are focused on the rear (or front) point, the front (or rear) point is It is observed without blurring.

Here, conventionally, the diameter of the pupils 14 and 16 is 5
In the case of mm, when the right-eye corresponding parallax image 50 and the left-eye corresponding parallax image 52 are incident, the focus adjustment participation distance is 2 to 3 m. On the other hand, the parallax image 5 corresponding to the right eye in the range of 1 mm in diameter.
0, when the parallax image 52 corresponding to the left eye is restricted so as to be incident, the focus adjustment participation distance is 0.4 to 0.6 m and the diameter is 5 mm.
Is 1/5 that of the image of FIG. Here, the focus adjustment participation distance is a distance from the eye to the stereoscopic image and a distance at which blur due to focus adjustment is felt, and an image at a distance longer than that is hardly blurred even if the focus is changed. . Therefore, the aperture of the image incident on the pupil is limited to, for example, 1 mm,
And a stereoscopic image farther than the focus adjustment participation distance, for example, 0.6
If the image is displayed at a position of m or more, the blur of the stereoscopic image is reduced.

Therefore, when the observer views the virtual images 70 and 72 with the right eye 10 and the left eye 12, respectively, the lens 10a,
Even if the focal point of 12a is adjusted not to the position of the virtual images 70 and 72 but to the position of the stereoscopic image appearing in the space before or after it, the images 60 and 62 on the retinas 10c and 12c are hardly blurred. Therefore, there is no binocular rivalry, and natural stereoscopic vision becomes possible.

Here, the transmissive liquid crystal panels 22 and 32
It is preferable that the display is driven based on image information captured in advance by a camera with a pinhole lens.

FIG. 32 shows the principle of photographing using a camera with a pinhole lens. Objects 900 and 902 are placed on the photosensitive surface 101 via pinhole lenses 1010 and 1020.
2,1022. As described above, an image captured using the camera with a pinhole lens has a large depth of focus, and the objects 900 and 902 are imaged on the photosensitive surfaces 1012 and 1022 without blurring. Therefore, when such images are displayed on the transmissive liquid crystal panels 22 and 32, the objects 900 and 902 shown in FIG. 31 are observed with less blur.

In FIG. 1, one corresponding parallax image is incident on one pupil. Even if a plurality of corresponding parallax images are incident on a plurality of small areas of one pupil, visual field conflict can be prevented. . FIG. 34 shows an example in which two corresponding parallax images (region parallax images) are incident on one pupil. Note that FIG.
, Members having the same functions as those shown in FIG. 1 are denoted by the same reference numerals. In FIG. 34, two point light sources 30A and 30B that emit light in a time-division manner, and a liquid crystal panel 52 that switches and displays a corresponding parallax image at high speed in accordance with the emission of the point light source are time-divided into two regions in one frame. Causes two different corresponding parallax images to enter the pupil. In this case, by narrowing the aperture of each area, only the part of the stereoscopic image that is out of focus is blurred, and natural stereoscopic vision in which visual field conflict is prevented can be realized.

FIG. 5 shows still another modification of the embodiment shown in FIG. The embodiment shown in FIG. 5 is different from the embodiment shown in FIG. 1 in that a condensing lens 26 as condensing optical means is disposed between a point light source 20 for the right eye and a transmissive liquid crystal panel 22. Point light source 30 for left eye and transmissive liquid crystal panel 3
2 is that a condenser lens 36 as a condenser optical means is disposed.

As a result, as shown in FIG.
Lights 0 and 30 are condensed by the condensing lenses 26 and 36, and are converted into parallel lights to be incident on the transmissive liquid crystal panels 22 and 32. Therefore, the right eye 1 via the eyepieces 24 and 34
There is an advantage that the amount of light incident on the zero and the left eye 12 increases, and the image becomes brighter.

In the embodiment shown in FIG. 6, only the configuration for guiding the right-eye corresponding parallax image 50 to the right eye 10 is shown, and the configuration for the left eye is omitted. In this case, the observer's right eye 1
Only the half mirror 80 exists in the field of vision in front of the 0 and the left eye 12, and the observer can observe a stereoscopic image,
It is also possible to look ahead through the half mirror 80.

For this purpose, the point light source 20 for the right eye, the transmissive liquid crystal panel 22 and the eyepiece 24 are arranged above the field of view of the right eye 10. Light from the eyepiece 24 is reflected by the half mirror 80 and guided to the right eye 10. Although not shown, the configuration for guiding the left-eye corresponding parallax image 52 to the left eye 12 is the same.

FIG. 7 shows the eyepiece 24 of FIG.
An example in which it is changed to 0 is shown. According to the configuration of FIG. 7, the parallax image 5 corresponding to the right eye formed by the transmissive liquid crystal panel 22.
0 is once reflected toward the front of the field of view by the half mirror 80, then condensed by the concave mirror 90, passes through the half mirror 80, and enters the right eye 10. Also in this case, the observer can observe a three-dimensional image and can also look ahead through the half mirror 80 and the concave mirror 90.

FIG. 8 shows an example in which the half mirror 80 and the concave mirror 90 shown in FIG. 7 are changed to one lens block 100 made of, for example, plastic.

In the above-described apparatus, the observation hole for the parallax image is located on the pupil, but is fixed in position. Since the position of the pupil changes when viewing an image with a wide field of view, the observation hole moves away from the pupil, and the field of view is limited. The stereoscopic image display device shown in FIG. 9 is obtained by modifying the device of FIG. 1 into a pupil tracking system.

The stereoscopic image display device shown in FIG. 9 is a surface light source 11 in which a plurality of point light sources 110a are two-dimensionally arranged in a horizontal line or a vertical line and a horizontal line.
0, and further, a camera 120 that senses the position information of the pupil 14 of the right eye 10, and a light emission position controller 130 that selects one of the point light sources 110a of the surface light source 110 based on the camera output and controls the light emission. Are provided.

Then, the position of the pupil 14 of the right eye 10 is constantly monitored by the camera 120 via the half mirror 80. When the position of the pupil 14 changes based on the photographing result of the camera 120, the light is focused by the light emission position control unit 130 from the surface light source 110 to a position smaller than the diameter of the pupil 14 at the position of the pupil 14. One illuminated point light source 110a is selected to emit light. Note that the left eye 1
A similar configuration is adopted for the second. In addition, surface light source 1
10 may be a two-dimensional image display device. in this case,
As shown in FIG. 10, a ring-shaped infrared light source 48 is provided on the optical axis of the camera, and the output of the camera is directly displayed on the two-dimensional image display device 110 as a light source, thereby enabling pupil tracking. That is, the light position control unit 130 is not required. 15 and 18 are modifications of FIG. In the case of FIG.
Since the camera and the infrared light source are separated from each other, the infrared light source does not have to be ring-shaped.

FIG. 20 shows only a right-eye part of a stereoscopic image apparatus capable of tracking a plurality of, for example, two parallax images from two places in a pupil. In FIG. 20, two light sources 110a1 and 110a2 selected from among the surface light sources 110 by the light emission position control unit 130 emit light in a time division manner, and two corresponding parallax images are made to enter from two small areas of one pupil. ing.

Further, as shown in FIG. 21, a large number of small light-emitting portions are two-dimensionally arranged, a large number of observation holes smaller than the pupil are set within the pupil movement range, and a large number of corresponding parallax images are incident in a time-division manner. Then, the field of view can be expanded without using the detection camera 284 and the light emission position control unit 286. Further, as shown in FIG. 22, small light emitting units are arranged one-dimensionally,
Light emission may be performed sequentially.

(Second Embodiment) FIG. 11 is a schematic explanatory view of a stereoscopic image display apparatus according to a second embodiment of the present invention, in which the right eye 10 displays a parallax image corresponding to the right eye. And the configuration corresponding to the left eye 12 is omitted.

The apparatus shown in FIG. 11 is different from the first embodiment described above in that the right eye point light source 20 and the transmissive liquid crystal panel 2
Instead of 2, a direct-view display device such as a CRT 140 is used as the parallax image display means. As this type of direct-view display device, a direct-view liquid crystal display device or the like can be used in addition to the CRT 140.

In order to form the right-eye-corresponding parallax image 150 displayed on the display surface of the CRT 140 on the retina 10c of the right eye 10, a light-shielding mask 142 serving as an incident limiting means having a pinhole 142a, and an imaging optics A means such as an imaging lens 144 and an eyepiece optical means such as an eyepiece 146 are provided.

The imaging lens 144 outputs the parallax image 15 corresponding to the right eye.
0 is formed, and the eyepiece 146 allows the observer to observe the formed right-eye parallax image 150 as a virtual image. The light emitted from the pinhole 142a of the light shielding mask 142 provided between the imaging lens 144 and the eyepiece 146 is transmitted to the pupil of the right eye 10 of the observer by at least one of the imaging lens 144 and the eyepiece 146. It is focused on an observation hole smaller than 14.

According to the second embodiment, the CRT 1
When observing a stereoscopic image based on the parallax image displayed by 40, the light emitted from the pinhole 142 a of the light-shielding mask 142 is always stopped down regardless of the size of the entrance aperture of the image to the pupil 14 regardless of the size of the pupil 14. ing. In this way, the depth of focus of the lens of both eyes will be deep, and even if the lens is focused on a stereoscopic image that is away from the parallax image display surface, the parallax image will not be blurred, so it is possible to observe natural stereoscopic images with little visual field conflict Become. Therefore, also in this case, the same effect as that of the first embodiment can be obtained.

On the basis of the photographing result of the detection camera 170, the shutter opening drive control unit 180 causes
The optical shutter 160a different from the one selected at is selected and opened. As a result, the parallax image 150 corresponding to the right eye can be made to enter the pupil 14 from a region smaller than the diameter of the pupil 14. Also, the shutter array 160
