For example, when connecting the area of graph return sexual reflex parts 141a～143a again and to obtain and be the area of glasses 103 when being positioned at the reference position, distance calculation portion 122, under connecting the area of graph return sexual reflex parts 141～143 again and to obtain than the situation that to connect the area of graph of returning sexual reflex parts 141a～143a again and obtaining big, judge that then glasses 103 are positioned at than on the near position, reference position, in addition, under connecting the area of graph return sexual reflex parts 141～143 again and to obtain, judge that then glasses 103 are positioned at than on the position far away, reference position than the situation that to connect the area of graph of returning sexual reflex parts 141a～143a again and obtaining little.In addition, distance calculation portion 122 has the rate of change data corresponding with the rate of change of distance that make area in advance, and it goes out from image display device 102 to glasses 103 distance according to this data computation.

Wherein, in current step S3, as shown in Figure 5, the area of graph return area of graph that sexual reflex parts 141～143 obtain and connection to return sexual reflex parts 141a～143a to obtain again again is identical owing to connecting, so distance calculation portion 122 determines that glasses 103 are positioned at reference position (for example, 103 distance is 3m from image display device 102 to glasses).

In addition, above-mentioned example is an example, for example, also can compare by the length to line segment 142a-143a and line segment 142-143 and calculate from image display device 102 to glasses 103 distance.In addition, for example, also can be by distance calculation portion 122 be connected with infraluminescence LED126, and instrumentation used how long arrive infrared camera 127 actually behind infraluminescence LED126 ejaculation light, thus calculating from image display device 102 to glasses 103 distance.

Then, in the action of the stereoscopic display device 101 of present embodiment 1, anaglyph generating unit 123 generates and the result of calculation (testing result of tilt detecting device) of inclination calculating part 121 and the corresponding anaglyphs (step S4) of result of calculation (distance detection device) of distance calculation portion 122.

Specifically, anaglyph generating unit 123 is according to the result of calculation of inclination calculating part 121 and the result of calculation of distance calculation portion 122, selects suitable data and generate right eye with image and left eye image from 3 dimension data of storage in advance.

Wherein, as mentioned above, in the action of current stereoscopic display device 101, the angle of glasses 103 is horizontalitys, and the position of glasses 103 is reference positions.So, for example, when showing the image of dice, as shown in Figure 6A, when beholder's face did not have inclination and beholder to be in the reference position, the identical view data of image in the time of will seeing dice with right eye was elected the right eye image as, shown in Fig. 6 B, when beholder's face did not have inclination and beholder to be in the reference position, the identical view data of image in the time of will seeing dice with left eye was elected the left eye image as.

Then, when the left eye among the anaglyph that in anaglyph generating unit 123, is generated with view data input left-eye image with projector's 124 inputs right eye with view data input eye image during with projector 125, then from left-eye image with projector 124 projection left eye image on screen 128, from eye image with projector 125 projection right eye image on screen 128.

Wherein, circular polarizing disk 341, be polarized to being seen as the polarized light of left hand direction to the direction of glasses 103 with the image light of image to the left eye of projection on the screen 128 with projector 124 from left-eye image, circular polarizing disk 351, be polarized to be seen as the polarized light of dextrorotation direction to the direction of glasses 103 from image display device 102 with the right eye of projector's 125 projections image light with image from eye image from image display device 102.

The glasses 103 of the stereoscopic display device 101 of present embodiment 1, because right eye constitutes only through the circular polarizing disk that is seen as the circularly polarized light of dextrorotation direction from image display device 102 to the direction of glasses 103 with seeing through portion 131, left eye constitutes only through the circular polarizing disk that is seen as the circularly polarized light of left hand direction from image display device 102 to the direction of glasses 103 with seeing through portion 132, so right eye only arrives beholder's right eye with image, left eye then only arrives beholder's left eye with image.Its result, beholder's brain is identified as space image with image and left eye with the synthetic and viewed person of image with right eye.

After so a series of EOP (end of program), the stereoscopic display device 101 of present embodiment 1 returns step S1 once more.

Secondly, in the step S1 of the action of the stereoscopic display device 101 of present embodiment 1, at image as shown in Figure 7, return sexual reflex parts 142 to return sexual reflex parts 141 to be positioned under the situation in left side of line segment 142-143 again being configured to linearity up and down again with returning sexual reflex parts 143 again, inclination calculating part 121, for example by line segment 142a-143a and line segment 142-143 are compared, and then to the position of returning sexual reflex parts 141a again with return the position of sexual reflex parts 141 to compare again, determine glasses 103 90 degree (step S2) that on image, have been tilted to the left.

In addition, distance calculation portion 122, image as shown in Figure 7, return the area of the image that sexual reflex parts 141～143 obtain littler again owing to connecting, so the position of determining glasses 103 is for example than reference position 1m far away (step S3) than connecting the area of graph of returning sexual reflex parts 141a～143a to obtain again.

Then, anaglyph generating unit 123 can be confirmed the top and bottom of the dice shown in Fig. 8 A, the B according to the result of calculation of inclination calculating part 121 and the result of calculation of distance calculation portion 122, and then generates than Fig. 6 A, anaglyph (step S4) that the B dice is little.

Therefore, though beholder's head inclination or when mobile, owing to can show the suitable anaglyph corresponding with its action, thus can show the anaglyph corresponding with the inclination of glasses 103, thus more natural space image can be shown.

To this, because existing stereoscopic display device only detects the position of glasses, thus can't generate the anaglyph corresponding with the inclination of glasses, thus the anaglyph corresponding can't be shown with beholder's action.Therefore, on same position, only during head inclination, will keep to former state the anaglyph shown in Fig. 6 A, the B as the beholder.

As mentioned above, according to the stereoscopic display device 101 of present embodiment 1,, can show more natural space image by showing the anaglyph corresponding with the inclination of glasses 103.

In addition, in the stereoscopic display device 101 of present embodiment 1, owing to be used to calculate the inclination of glasses 103 and the component parts of distance is only to have disposed reflection part 104 in glasses 103 sides, and on glasses 103, do not need to be provided with the device of electric power supply source etc., can calculate the inclination and the distance of glasses 103 so can increase the weight of glasses 103 hardly.

In addition, in the stereoscopic display device 101 of present embodiment 1, owing to having used infrared light, can not impact to anaglyph so can calculate the inclination of glasses 103 and distance for the inclination of calculating glasses 103 and distance.In addition, though also can use ultraviolet light, consider preferably to use infrared light from price and security aspect as the light that is not included in the visibility region.

In addition, in the stereoscopic display device 101 of present embodiment 1, owing to return sexual reflex parts 104 to be configured on each summit of isosceles triangle again, so can both calculate the inclination angle of glasses 103 reliably for all anglecs of rotation of glasses 103.But the present invention is not limited to this, returns the layout of sexual reflex parts 104 again so long as calculate the layout of the anglec of rotation of glasses 103 exactly and get final product.In addition, for example, also can only dispose 1 on the image shape and the anglec of rotation change accordingly return the sexual reflex parts again, and utilize this shape of returning the sexual reflex parts again to calculate the inclination of glasses 103.

In addition, in the stereoscopic display device 201 of present embodiment 1, of the present invention wear pluck judgment means constitute possess judging part 221, infraluminescence LED226, infrared camera 227 and return sexual reflex parts 204 again.

Below, describe referring to the action of the process flow diagram of Figure 12 the stereoscopic display device 201 of the present embodiment 1 of such formation.

As shown in figure 12, in the action of stereoscopic display device 201, at first, utilize infrared camera 227 to obtain a plurality of images (step S11).Wherein because infrared camera 227 is the devices that make infrared ray visibleization, so that from infraluminescence LED226 ejaculation and be configured in returning visibleization of infrared ray that sexual reflex parts 204 reflect again and obtaining image on the glasses 203.

Then, after having obtained a plurality of images, judging part 221 is judged the state of plucking (step S12) of wearing of glasses 203 according to the shooting results (image) of infrared camera 27.

Specifically, judgment means 221 detects the action of returning sexual reflex parts 204 again from a plurality of images of being obtained by infrared camera 227, when not returning the action of sexual reflex parts 204 again at the appointed time, judges that then glasses 203 are for taking state.

In addition, judgment means 221 detects the action of returning sexual reflex parts 204 again from a plurality of images of being obtained by infrared camera 227, when the action of returning sexual reflex parts 204 again being arranged at the appointed time, judges that then glasses 203 are for wearing state.

Then, in the action of the stereoscopic display device 201 of present embodiment 1, image production part 223 according to the judged result of judging part 221 generate anaglyph or just the right eye among the anaglyph with image or left eye with in the image either party (step S13).

For example, in step S12, when judging glasses 203 when wearing state, image production part 223 suitable data of selection and generate right eye with image and left eye image from 3 dimension data of storage in advance.

In more detail, for example, when showing the image of dice, as shown in FIG. 13A, the identical view data of image in the time of will seeing dice with right eye is elected the right eye image as, and shown in Figure 13 B, the identical view data of image in the time of will seeing dice with left eye is elected the left eye image as.

Then, left eye among the anaglyph that generates in anaglyph generating unit 223 is imported left-eye image projector 224 with view data, and right eye is with view data input eye image during with projector 225, from left-eye image with projector 224 projection left eye image on screen 228, from eye image with projector 225 projection right eye image on screen 228.

Wherein, circular polarizing disk 441, be polarized to seeing the polarized light of left hand direction to the direction of glasses 203 with the image light of image to the left eye of projection on the screen 228 with projector 224 from left-eye image, circular polarizing disk 451, be polarized to be seen as the polarized light of dextrorotation direction to the direction of glasses 203 from image display device 202 with the right eye of projector's 225 projections image light with image from eye image from image display device 202.

The glasses 203 of the stereoscopic display device 201 of present embodiment 1, because right eye constitutes only through the circular polarizing disk that is seen as the circularly polarized light of dextrorotation direction from image display device 202 to the direction of glasses 203 with seeing through portion 231, and left eye constitutes only through the circular polarizing disk that is seen as the circularly polarized light of left hand direction from image display device 202 to the direction of glasses 203 with seeing through portion 232, so right eye only arrives beholder's right eye with image, left eye then only arrives beholder's left eye with image.Its result, beholder's brain is synthetic with image with image and left eye with right eye, thus the beholder is identified as space image.

In addition, in step S12, when judging glasses 203 when taking state, image production part 223 is selected suitable data and is only generated right eye with in image or the left eye usefulness image either party from 3 dimension data of storage in advance.

For example, when only generating right eye and use image, as shown in FIG. 13A, the identical view data of image in the time of will seeing dice with right eye is elected right eye as and is only generated this right eye image with image.Then, by right eye from projector 225 input to eye image that in image production part 223, generate with the data of image from eye image with projector 225 projection right eye image only on screen 228.

Otherwise when only generating left eye and use image, shown in Figure 13 B, the identical view data of image in the time of will seeing dice with left eye is elected left eye as and is only generated this left eye image with image.Then, by left eye from projector 224 input to left-eye image that in image production part 223, generate with the data of image from left-eye image with projector 224 projection left eye image only on screen 228.

As mentioned above, when utilizing judging part 221 to judge glasses 203 when taking state, then the beholder has taken glasses 203.Therefore, though the right eye on the screen 228 all will arrive with image with image and left eye among two of beholder each, but in the stereoscopic display device 210 of present embodiment 1, as mentioned above, since when judge glasses 203 only show when taking state right eye among the anaglyph with image or left eye with in the image either party, so become 2 dimension demonstrations.

Then, after so a series of EOP (end of program), the stereoscopic display device 201 of present embodiment 1 returns step S11 once more.

As mentioned above, stereoscopic display device 201 according to present embodiment 1, pluck judgment means (judging part 221, infraluminescence LED226, infrared camera 227 and return sexual reflex parts 204 again) and switch automatically according to the state of plucking of wearing of glasses 203 that 3 dimensions show and 2 dimensions show owing to utilize to wear, so can not make the beholder bear operation and wear the state of plucking regardless of glasses and how can both realize good show state for the beholder.

In addition, in the stereoscopic display device 201 of present embodiment 1, owing to be used to judge that the component parts of wearing the state of plucking of glasses 203 has just disposed reflection part 204 in glasses 203 sides, and on glasses 203, do not need to be provided with the device of electric power supply source etc., can increase the weight of glasses 203 hardly so can judge the wearing the state of plucking of glasses 203.

In addition, in the stereoscopic display device 201 of present embodiment 1,, can not impact to anaglyph so can judge the wearing the state of plucking of glasses 203 owing to for the state of plucking of wearing of judging glasses 203 has used infrared light.In addition, though also can use ultraviolet light, consider preferably to use infrared light from price and security aspect as the light that is not included in the visibility region.

(embodiment 2)

Below, the embodiment 2 of mode 2 of the present invention is described.In addition, present embodiment 2 just glasses 203 wear that to pluck determination methods different with the foregoing description 1.For this reason, in the explanation of present embodiment 2, for omitting or simplify its explanation with the same part of the foregoing description 1.

In the stereoscopic display device of present embodiment 2, the action in the step 12 is different with the stereoscopic display device of the foregoing description 1.

Specifically, the stereoscopic display device of present embodiment 2, in step S12, judging part 221 is from the inclination angle of the image detection glasses 203 that obtained among step S11, and judges the state of plucking of wearing of glasses 203 according to the inclination angle of these detected glasses 203.

In more detail, judging part 221 calculates the relative position relation of returning sexual reflex parts 241～243 again by calculating each coordinate of returning sexual reflex parts 241～243 again, and calculates with the inclination of carrying out glasses 103 of comparing of the coordinate of returning the sexual reflex parts again of storage in advance.

For example, when the coordinate of returning the sexual reflex parts again of storage in advance be glasses 203 for horizontality the time coordinate time, returning again by to horizontality the time returns sexual reflex parts 141～143 to compare to calculate actual glasses 103 to be offset how many degree on which sense of rotation in sexual reflex parts and the image again.

Then, when the inclination angle of glasses 203 broke away from the scope of appointment, then judging part 221 judged that glasses 203 are for taking state.

In addition, when in the scope of the inclination angle of glasses 203 in appointment, then judging part 221 judges that glasses 203 are for wearing state.

In the stereoscopic display device of such present embodiment 2, also can access the effect same with the stereoscopic display device of the foregoing description 1.

(embodiment 3)

Below, the embodiment 3 of mode 2 of the present invention is described.In addition, present embodiment 3 also is that to have only wearing of glasses 203 to pluck determination methods different with the foregoing description 1.For this reason, in the explanation of present embodiment 3, for also omitting or simplify its explanation with the same part of the foregoing description 1.

In the stereoscopic display device of present embodiment 3, the action in the step 12 is different with the stereoscopic display device of the foregoing description 1.

Specifically, the stereoscopic display device of present embodiment 3, in step S12, judging part 221 detects the position of beholder's iris from the image that is obtained among step S11, and according to the state of plucking of wearing of the position judgment glasses 203 of this detected iris.

Since people's iris with return the sexual reflex parts that light is reflected to incident direction again, so the infrared light that penetrates from infraluminescence LED226 will be reflected at beholder's iris.Therefore, beholder's iris will be mirrored in the image that is obtained in infrared camera 227.In addition, when the beholder wears glasses 203, owing to be used as right eye that circular polarizing disk constitutes with seeing through portion 231 and left eye with blocking, so can not mirror in the image through portion 232 at the infrared light of beholder's iris reflex.But, when the beholder takes with wearing spectacles 203, in image beholder's iris be bound to mirror return again sexual reflex parts 204 near.

So, in present embodiment 3, judging part 221, for example when in image, confirmed two iris apart from the focus point of returning sexual reflex parts 241～243 again more than or equal to the position of 10cm (distance of appointment) on the time, judge that then glasses 203 are to take state, and keep this judgement.In addition, judging glasses 203 for to take under the state of state, when confirmed two iris apart from the focus point of returning sexual reflex parts 241～243 again smaller or equal to the position of 10cm on the time, then judge glasses 203 for wearing state, and keep this judgement.

In addition, as the infraluminescence LED226 of the stereoscopic display device of present embodiment 3, preferably use the LED that penetrates near infrared light.Since near infrared light have in the pupil of human eye part reflectivity low and in iris the high character of reflectivity, so by using the infraluminescence LED226 that penetrates near infrared light can carry out the identification of iris more reliably.

In the stereoscopic display device of such present embodiment 3, also can access the effect same with the stereoscopic display device of the foregoing description 1.

In addition, also the foregoing description 1～embodiment 3 combinations can be judged the state of plucking of wearing of glasses 203.
