Description

  The present invention relates to stereoscopic image observation glasses for observing an image displayed by a stereoscopic image display device as a stereoscopic image.

  In recent years, broadcasting of 3D (stereoscopic) video has been put into practical use with the progress of broadcasting technology. The 3D video can make the viewer perceive a solid by displaying different images with parallax between the left and right eyes of the viewer.

  As a method for observing a 3D image, for example, there is a method in which a left-eye image and a right-eye image having different polarization directions are projected in an overlapping manner, and this image is observed using a stereoscopic image observation lens including a polarization filter. There is also a method of alternately reproducing images taken from different left and right angles and observing with stereoscopic image observation glasses having a stereoscopic image observation lens composed of a liquid crystal shutter in which the left and right visual fields are alternately shielded (for example, Patent Document 1).

Japanese Patent Laid-Open No. 9-5904

  However, conventional stereoscopic image observation glasses having a polarizing filter and stereoscopic image observation glasses having a liquid crystal shutter have no refraction correction effect for adjusting the user's visual acuity. Therefore, a person who needs glasses for refraction correction for adjusting the visual acuity has to wear glasses for observing a stereoscopic image from above the glasses for refraction correction while wearing the glasses for refraction correction. As a result, since the two spectacles are worn, there is a problem that the spectacles are heavy and easily misaligned with each other. Furthermore, there has been a problem that the lenses for stereoscopic image observation of the glasses for stereoscopic image observation and the lenses of the glasses for refractive correction are in contact with each other, so that both lenses may be damaged.

  SUMMARY OF THE INVENTION An object of the present invention is to provide 3D image observation glasses that can not only observe a 3D image but also have a refractive correction function in consideration of the above problems.

  The refraction correcting lens is provided on the one surface side of the stereoscopic image observation lens, and the surface opposite to the facing surface is formed in a concave shape. As a result, a negative prescription power can be given to the refractive correction lens.

  Further, the refraction correcting lens is provided on the other surface side of the stereoscopic image observation lens, and the surface opposite to the facing surface is formed in a convex shape. The refraction correcting lens having a convex surface is a progressive refraction lens or a multifocal lens. Thereby, it can use as spectacles for both perspectives.

  The refraction correcting lens is provided with an engaging portion, and the frame main body is provided with an engaging claw that engages with the engaging portion. Therefore, the refractive correction lens can be easily fixed to the frame body.

  Further, a filler for closely attaching the refraction correction lens and the stereoscopic image observation lens is provided between the refraction correction lens and the stereoscopic image observation lens. Therefore, the gap between the refraction correction lens and the stereoscopic image observation lens can be filled.

  In addition, it is preferable that the position of the refractive correction lens is adjusted so that the optical center thereof matches the position of the eyes of the user.

The description will be given in the following order.

<1. First Embodiment>
1-1. Configuration Example of Stereoscopic Image Observation Glasses First, stereoscopic image observation glasses according to a first embodiment of the present invention (hereinafter referred to as “present example”) will be described with reference to FIGS.
FIG. 1 is a cross-sectional view showing the stereoscopic image observation glasses of this example, and FIG. 2 is an explanatory view showing a method of fixing the refractive correction lens according to the stereoscopic image observation glasses of this example.

  The stereoscopic image observation glasses 1 of this example are glasses that allow the user to experience a stereoscopic image by observing the stereoscopic image displayed on the display unit using the binocular parallax of the human left eye and right eye. The stereoscopic image observation glasses 1 of this example are liquid crystal shutter type glasses in which the left and right fields of view are alternately shielded.

  As shown in FIG. 1, the stereoscopic image observation glasses 1 of this example include a frame body 2, a pair of stereoscopic image observation lenses 3L and 3R attached to the frame body 2, and a pair of refraction correction lenses 4L, 4R and the control unit 11 that controls the stereoscopic image observation lenses 3L and 3R.

  The frame main body 2 has a rim 6 to which a lens is attached and an ear hooking portion 7 to be hung on the user's ear. Two openings 8L and 8R are provided on both sides of the rim 6 in the longitudinal direction, and a nose-hanging portion 6a that is applied to the user's nose is provided at the center thereof. Ear hooks 7 are attached to both ends of the rim 6 in the longitudinal direction.

  As shown in FIG. 2, engagement claws 9 that engage with engagement portions 12 of two refraction correction lenses 4 </ b> L and 4 </ b> R described later are provided on the outer edge portions of the openings 8 </ b> L and 8 </ b> R in the rim 6. ing. Then, two stereoscopic image observation lenses 3L and 3R and two refraction correction lenses 4L and 4R are attached so as to close the two openings 8L and 8R formed in the rim 6.

  The left stereoscopic image observation lens 3L is disposed in the left opening 8L formed on one side of the rim 6, and the right stereoscopic image observation lens 3R is formed on the right opening 8R formed on the other side of the rim 6. Is arranged. The left stereoscopic image observation lens 3L and the right stereoscopic image observation lens 3R are formed in a substantially flat plate shape, and both surfaces thereof are substantially flat. The left stereoscopic image observation lens 3L and the right stereoscopic image observation lens 3R are transmissive liquid crystal shutters.

  The left stereoscopic image observation lens 3L and the right stereoscopic image observation lens 3R are connected to the control unit 11, respectively. The control unit 11 is built in the two ear hooks 7 of the frame body 2. The control unit 11 alternately opens and closes the left stereoscopic image observation lens 3L and the right stereoscopic image observation lens 3R. As a result, the left and right visual fields of the user are alternately shielded by the two stereoscopic image observation lenses 3L and 3R, and light is transmitted only to the user's left eye 100L, or light is transmitted only to the right eye 100R.

  The timing for alternately opening and closing the left stereoscopic image observation lens 3L and the right stereoscopic image observation lens 3R is synchronized with the switching timing of the right eye image and the left eye image displayed on the display unit (not shown). . As a result, the left-eye image is projected only on the left eye 100L of the user, and the right-eye image is projected only on the right eye 100R. Therefore, the user can experience a stereoscopic image.

  Further, a left-side refraction correcting lens 4L is disposed opposite to the user-side surface 3a of the left stereoscopic image observation lens 3L, and the user-side surface 3a of the right-side stereoscopic image observation lens 3R is disposed on the user-side surface 3a. The right refraction correcting lens 4R is disposed to face the right refraction correcting lens 4R.

  The left refraction correcting lens 4L and the right refraction correcting lens 4R are lenses having a power corresponding to the prescription power of the user. Note that the left-side refraction correction lens 4L and the right-side refraction correction lens 4R of this example are refraction correction lenses having a prescription power of minus power and are formed in a concave lens shape.

  The left-side refraction correction lens 4L and the right-side refraction correction lens 4R have the same configuration, and therefore, the left-side refraction correction lens 4L will be described here, and the description of the right-side refraction correction lens 4R will be omitted. To do.

  The facing surface 4a facing the one surface 3a of the left stereoscopic image observation lens 3L in the left refraction correcting lens 4L is formed in a substantially flat shape that is a shape along the one surface 3a of the left stereoscopic image observation lens 3L. . As a result, the left refraction correcting lens 4L can be disposed close to the left stereoscopic image observation lens 3L. As a result, the gap between the left refraction correction lens 4L and the left stereoscopic image observation lens 3L can be reduced, and dust and dust enter between the left refraction correction lens 4L and the left stereoscopic image observation lens 3L. Can be difficult.

  Further, the surface 4b opposite to the facing surface 4a in the left-side refraction correcting lens 4L, that is, the surface 4b facing the user's eye 100L is a concave surface on which a prescription power of minus power is formed. Therefore, it is possible to make it difficult for the user's eyelashes to come into contact with the left side refraction correcting lens 4L. Further, by making the surface 4b facing the user's eyes 100L into a toroidal surface shape, an effect as a refraction correcting lens corresponding to the astigmatism power can be obtained.

  If the concave surface on which the prescription power is formed is formed on the display unit side, not only the gap between the left refraction correcting lens 4L and the left stereoscopic image observation lens 3L is increased, but the image is spread outwardly to the user. Is not preferable because a distorted image is projected.

  Further, as shown in FIG. 2, the engaging portion 12 is provided on the side surface portion 4c which is the edge surface of the left side refraction correcting lens 4L. Then, the left refraction correcting lens 4L is fixed to the frame main body 2 by engaging the engaging portion 12 of the left refraction correcting lens 4L with the engaging claw 9 of the frame main body 2.

  At this time, the optical center Q of the left refraction correcting lens 4L is set in accordance with the position of the user's eye 100L. In order to align the optical center Q of the left refraction correcting lens 4L with the position of the user's eye 100L, for example, the distance PD between the user's left eye 100L and the right eye 100R is measured.

  Although the example in which the refraction correcting lenses 4L and 4R and the frame main body 2 are fixed by the engagement by the engaging claw 9 and the engaging portion 12 has been described, the refraction correcting lenses 4L and 4R and the frame main body 2 are fixed. The method is not limited to this. For example, the refraction correcting lenses 4L and 4R may be fixed to the frame body 2 by adhesive fixing using an adhesive or other various fixing methods.

  Furthermore, in this example, the example in which the facing surface 4a of the left-side refraction correcting lens 4L is formed in a substantially planar shape has been described, but the present invention is not limited to this. For example, when the one surface 3a of the left stereoscopic image observation lens 3L is formed in a concave shape, the facing surface 4a of the left refraction correction lens 4L has a convex shape along the one surface 3a of the left stereoscopic image observation lens 3L. It is formed. That is, the facing surface 4a of the left refraction correcting lens 4L is appropriately set in a shape along the one surface 3a of the left stereoscopic image observation lens 3L facing the facing surface 4a of the left refraction correcting lens 4L.

  Further, in this example, the example in which the refraction correction lenses 4L and 4R are arranged on the user-side surface 3a of the stereoscopic image observation lenses 3L and 3R has been described. However, the refraction correction lenses 4L and 4R are for stereoscopic image observation. You may arrange | position on the other surface 3b of the display part side of the lenses 3L and 3R.

  However, if the refraction correction lenses 4L and 4R are arranged on the display unit side of the stereoscopic image observation lenses 3L and 3R, the distance between the left and right eyes 100L and 100R of the user and the refraction correction lenses 4L and 4R is increased. When the distance between the left and right eyes 100L and 100R of the user and the refraction correcting lenses 4L and 4R increases, the field of view that can be seen through the refraction correcting lenses 4L and 4R becomes narrower. In addition, since the refraction correcting lenses 4L and 4R are negative power lenses, the stereoscopic image is observed in a further reduced size than when the refraction correcting lenses 4L and 4R are arranged on the user side.

  At this time, if a concave surface having a prescription power is formed on the opposite surface of the refraction correction lenses 4L and 4R facing the stereoscopic image observation lens 3L, the refraction correction lenses 4L and 4R and the stereoscopic image observation lenses 3L and 3R The gap becomes larger and dust and dust are more likely to enter. Further, when a concave surface having a prescription power is formed on the surface on the display unit side of the refraction correcting lenses 4L and 4R, the image is curved and observed as described above.

  Therefore, in order to widen the field of view that can be seen through the refraction correcting lenses 4L and 4R and to allow the user to experience a more natural stereoscopic image, the user's left and right eyes 100L and 100R and the refraction correcting lenses 4L and 4R It is preferable to reduce the distance. Therefore, it is preferable that the refraction correcting lenses 4L and 4R are arranged on the user-side surface 3a rather than the other surface 3b on the display unit side in the stereoscopic image observation lenses 3L and 3R.

  As described above, according to the stereoscopic image observation glasses 1 of this example, the frame main body 2 is integrally provided with the stereoscopic image observation lens and the refraction correction lens. Thereby, the function of refraction correction can be given to the stereoscopic image observation glasses capable of observing the stereoscopic image. As a result, a stereoscopic image can be observed with a single pair of glasses, and the user can observe a beautiful stereoscopic image with a refractive correction lens having a prescription power according to the user.

  Therefore, unlike the conventional stereoscopic observation glasses, it is not necessary to wear two glasses for refraction correction and stereoscopic image observation glasses, and it is light for the user, and there is no possibility that the glasses are not shifted from each other. Furthermore, since the stereoscopic image observation lens and the refraction correction lens are integrally fixed to the frame body 2, it is possible to prevent the stereoscopic image observation lens and the refraction correction lens from rubbing against each other and scratching the lens. it can.

  In this example, the left-side refraction correction lens group 24L has been described with the first refraction correction lens 24A and the second refraction correction lens 24B. However, if the prescription power is sufficient, Only the second refraction correcting lens 24B may be used.

  Here, the second refraction correcting lens 24B, which is a convex lens, may be disposed on the user side in the left stereoscopic image observation lens 23L. However, when the convex surface is directed to the one surface 23a side of the left stereoscopic image observation lens 23L, the gap between the second refraction correction lens 24B and the left stereoscopic image observation lens 23L increases. Further, when the convex surface of the second refraction correcting lens 24B is directed to the user side, the user's eyelashes and the second refraction correcting lens 24B may come into contact with each other.
