Grand output adjustment part 73 in order to adjust alternative visually from display screen 51 grand go out grand output.Be specially, the control signal that grand output adjustment part 73 generates to make the grand output d of the alternative that user selects to reduce, and this control signal is exported to contents processing portion 2.Like this, in the middle of the shown alternative of display screen 51, can make the grand output of sense of vision of the alternative that user selected than the grand output of the sense of vision of non-selected alternative fewer.Thus, user can, from visually telling selecteed alternative and non-selected alternative, therefore can improve user's visibility and operability.

The < layout changing > of portion

Layout changing portion 74 is in order to change the layout of the alternative showing on display screen 51.At this, layout refers to: on 2 dimensions or the 3 dimension space coordinate systems, have the configuration mode of the object of position and size and profile attribute.For example, in the time that the picture of display screen 51 is combined into by set of pixels, position, size are expressed taking point (pixel) as unit conventionally.

Be specially, in the time that region setting part 71 has reset surveyed area, layout changing portion 74, according to the coordinate information of the surveyed area resetting, generates the control signal that the demonstration interval of the alternative of demonstration in display screen 51 is widened, and this control signal is exported to contents processing portion 2.

Thus, can be with the surveyed area resetting, widen the demonstration interval of the alternative being presented in display screen 51, thereby can improve user's visibility and operability.

The setting > of < region setting part to surveyed area

Below, according to Fig. 2 and Fig. 3, the setting that region setting part 71 carries out surveyed area is described once.Region setting part 71, in the time setting surveyed area, is calculated as the extensive magnitude and the direction of expansion that expand surveyed area and will be additional.

The computing method > of < extensive magnitude

First, carry out the computing method of the extensive magnitude of the surveyed area that declare area configuration part 71 sets with reference to Fig. 2 and Fig. 3.

Fig. 2 is the mode chart of the computing method the extensive magnitude of surveyed area calculated for declare area configuration part 71.In Fig. 2, P1 is the viewing area of alternative OB on display screen 51; P2 be the alternative OB that sees of user depending on recognizing position; A is the surveyed area on touch screen 52, and it is used for detecting the input operation that user makes to alternative OB; P3 is, seems the view field on along the direction projection perpendicular to display screen 51 to touch screen 52 in the alternative OB depending on recognizing position P2; I is the region that the user that knows according to experimental result can contact.

As shown in Figure 2, surveyed area A is made up of fundamental region A1 and enlarged area A2.Fundamental region A1 is located on the viewing area P1 of the shown alternative OB of display screen 51, and the size of fundamental region A1 is identical with viewing area P1., fundamental region A1 is the equal of the surveyed area a1 on the existing touch screen type three-dimensional display screen 151 shown in Fig. 9.

By 3 d display device 1, from user's angle, the upper shown alternative OB of the viewing area P1 of display screen 51 can seem in depending on recognizing position P2.Learn according to experimental result: in these cases, when user is to seeming in the time that the alternative OB depending on recognizing position P2 carries out input operation, user can touch certain position in the contact area I including fundamental region A1 and the P3 of view field pell-mell.Why this phenomenon can occur, be the cause varying with each individual due to user's visual sense and body sense.

Therefore in technology in the past, when there is position deviation between user's contact position and viewing area P1 (fundamental region A1) time, touch screen 52 just cannot detect the input operation that user makes alternative OB.

To this, region setting part 71 expands sets out than alternative OB the large surveyed area A of the viewing area P1 on display screen 51.Be specially, region setting part 71 is set out by fundamental region A1 and enlarged area A2 and is added the surveyed area A forming.

Below, the computing method example that region setting part 71 calculates the extensive magnitude of surveyed area A is described once.

< computing method 1>

First, the computing method 1 of the extensive magnitude of surveyed area A are described with reference to Fig. 2.

The longitudinal direction of surveyed area A (y axle) extensive magnitude is made as to AH (unit is mm) (with reference to Fig. 4), and region setting part 71 calculates longitudinal direction extensive magnitude AH according to following calculating formula 1.

AH[mm]=SH × (h-d)/(L-d) [mm] ... (calculating formula 1)

Equally, the transverse direction of surveyed area A (x axle) extensive magnitude is made as to AW (unit is mm) (with reference to Fig. 4), region setting part 71 calculates transverse direction extensive magnitude AW according to following calculating formula 2.

AW[mm]=SW × (h-d)/(L-d) [mm] ... (calculating formula 2)

In above-mentioned calculating formula 1 and calculating formula 2, L is the distance (unit is mm) between display screen 51 and eyes of user, h be alternative OB visually from display screen 51 grand go out grand output (unit is mm), d is to the distance (unit is mm) for detecting till the position of user input operation from display screen 51, SH is the longitudinal direction length (unit is mm) of the display screen 51 when the short transverse of input display 5 delimited as longitudinal direction, SW (without diagram) is the transverse direction length (unit is mm) of the display screen 51 when the Width of input display 5 delimited as transverse direction.

In the present embodiment, if adopt touch screen 52 to be used as entering apparatus, be the thickness of touch screen 52 from display screen 51 till for the distance d of the position of detecting user's input operation.In addition, if adopt range sensor to be used as entering apparatus, from display screen 51 till for the distance d of the position of detecting user's input operation be: from display screen 51, till range sensor detects the detection distance of the active position of user's input operation.

Distance L between display screen 51 and eyes of user can be for example: the mean value of the spacing of the spacing of display screen 51 and user's right eye and display screen 51 and user's left eye.It can be maybe the spacing of one party in display screen 51 and right and left eyes.

Like this, region setting part 71 is the longitudinal direction extensive magnitude AH that calculate according to above-mentioned calculating formula 1, appends to wherein at least in the direction of one end of y axle two ends of fundamental region A1.In addition, region setting part 71 is the transverse direction extensive magnitude AW that calculate according to above-mentioned calculating formula 2, appends to wherein at least in the direction of one end of x axle two ends of fundamental region A1.Thus, region setting part 71 is set out by fundamental region A1 and enlarged area A2 and is added the surveyed area A forming.

As mentioned above, region setting part 71 uses above-mentioned calculating formula 1 and calculating formula 2 to calculate extensive magnitude AH, AW, and sets surveyed area A.Just can make thus surveyed area A expand the degree that the P3 of view field is included to.Like this, just can make surveyed area A and contact area I be integrated, even if therefore there is position deviation between viewing area P1 (fundamental region A1) and user's contact position, also can detect effectively the input operation that user does alternative OB.

In addition, if use computing method 1 to calculate the extensive magnitude of surveyed area A, the longitudinal direction extensive magnitude AH of surveyed area A is set in SH × (h-d)/600[mm by favored area configuration part 71] above SH × (h-d)/(100-d) below [mm].Equally, the transverse direction extensive magnitude AW of surveyed area A is set as SW × (h-d)/600[mm by favored area configuration part 71] above SW × (h-d)/(100-d) below [mm].

Generally speaking, the average length of people's arm is about 600mm.Therefore, (L-d) is decided to be to 600mm, and the expansion lower limit of enlarged area A2 is decided to be to SH × (h-d)/600[mm] or SW × (h-d)/600[mm].By like this, in the situation that user elects to alternative OB with finger, when user is when carrying out input operation from display screen 51 position farthest, can prevent the maloperation that position deviation now causes.

In addition, in order to make user correctly be familiar with the alternative OB showing on display screen 51, more than the distance between display screen 51 and eyes of user generally need to keep about 100mm.Therefore L is decided to be to 100mm, and the expansion higher limit of enlarged area A2 is decided to be to SH × (h-d)/(100-d) [mm] or SW × (h-d)/(100-d) [mm].By like this, when user is when carrying out input operation from the nearest position of display screen 51, can prevent the maloperation that position deviation now causes.

< computing method 2>

Next, the computing method 2 of the extensive magnitude of surveyed area A are described with reference to Fig. 3.

Fig. 3 is the mode chart of other computing method of the extensive magnitude of surveyed area A being calculated for declare area configuration part 71.As shown in Figure 3, the right eye that can the realize stereo visual effect image of the alternative OB that display screen 51 is shown and left eye are made as p (unit is mm) by the position deviation amount between image, now favored area configuration part 71 is decided to be vertical (y axle) direction extensive magnitude AH of surveyed area A below the above SH × p/ of 20 × p/ (75+p) [mm] (75+p) [mm], and the horizontal stroke of surveyed area A (x axle) direction extensive magnitude AW is decided to be below the above SW × p/ of 20 × p/ (75+p) [mm] (75+p) [mm].

At this, while learning by experiment the image that user shows on audiovisual display screen 51, because the action of health can produce at least sight line change in location of 20mm left and right often.Therefore the expansion lower limit of enlarged area A2 is at least decided to be to 20 × p/ (75+p), so just can prevents the maloperation that the sight line change in location because following user's body action causes.

In addition, in the axial space of z, in the space of delimiting perpendicular to the direction of display screen 51, if there are user's eyes, the maximum fore-and-aft distance between vertical projection position and the viewing area P1 of alternative OB of eyes of user on display screen 51 is just SH, and maximum transversal distance is just SW.Therefore, the expansion higher limit transversely and longitudinally of enlarged area A2 is respectively decided to be to SH × p/ (75+p) [mm], SW × p/ (75+p) [mm], so just can effectively surveyed area A be expanded to alternative OB that user sees depending on recognizing the below of position P2.

In addition, computing method 2 do not need to use the grand output h of distance L between display screen 51 and user, alternative OB and from display screen 51 to the distance d till effective detection position of input operation, therefore region setting part 71 can easily be set surveyed area A.

The calculating > of < direction of expansion

Then,, with reference to Fig. 2 and Fig. 4, the computing method of region setting part 71 being calculated to the direction of expansion of surveyed area A describe.

Generally speaking, user's contact position has the tendency at the viewing area P1 deflection display screen 51 center of the alternative OB showing from display screen 51.As shown in Figure 2, in the time that alternative OB is presented at the top of user's eye-level display, user has the tendency that touches fundamental region A1 below to example.

Therefore,, by the middle auxocardia to display screen 51 by surveyed area A, just can make the direction of expansion of surveyed area A consistent with the offset direction of user's contact position.Be specially, the centre coordinate of the viewing area P1 of the centre coordinate of region setting part 71 to display screen 51 and alternative OB compares, and calculates thus the direction of expansion of surveyed area A.

Fig. 4 (a)～(d) is a routine vertical view of the direction of expansion of surveyed area A.As shown in Fig. 4 (a), region setting part 71 can add enlarged area A2 in the mode of surrounding fundamental region A1 periphery, sets thus surveyed area A.Therefore no matter user's eyes with respect to alternative OB in where, even if there is above-mentioned position deviation, also can detect effectively the input operation that user does alternative OB.

In addition, if region setting part 71 is the middle auxocardias to display screen 51 by surveyed area A, as shown in Fig. 4 (b)～(d), set surveyed area A.For example, in the time that the centre coordinate of display screen 51 is positioned at the lower right of centre coordinate of the viewing area P1 of alternative OB, region setting part 71 is as Fig. 4 (b), and the right to fundamental region A1 and base add enlarged area A2, set thus surveyed area A.

In addition, in the time that the centre coordinate of display screen 51 is positioned at the top of centre coordinate of the viewing area P1 of alternative OB, region setting part 71, as Fig. 4 (c), to the additional enlarged area A2 of the top margin of fundamental region A1, is set surveyed area A thus.

In addition, in the time that the centre coordinate of display screen 51 is positioned at the left of centre coordinate of the viewing area P1 of alternative OB, region setting part 71, as Fig. 4 (d), to the additional enlarged area A2 in the left side of fundamental region A1, is set surveyed area A thus.

As shown in Fig. 4 (b)～(c), set surveyed area A by the middle auxocardia to display screen 51, can prevent from unnecessarily setting surveyed area A, and prevent that the surveyed area A setting from overlapping.

Processing > in < 3 d display device

Below, with reference to Fig. 5 and Fig. 6, the processing in the 3 d display device 1 of present embodiment is described.

< processing example 1>

First the base conditioning of the 3 d display device 1 of present embodiment is described, i.e. processing example 1 with reference to Fig. 5.

Fig. 5 is the process flow diagram of the processing example 1 of the 3 d display device 1 in embodiment of the present invention.As shown in Figure 5, processing example 1 has step S1～S11.

First, the picture material (S1) being recorded in media M etc. is read by contents processing portion 2, and generates the view data of each unit image.

Secondly, contents processing portion 2 judge in the view data of per unit image of generation whether contain the alternative OB (S2) such as button.

If do not contain alternative OB (being "No" at S2) in view data, contents processing portion 2 makes the coordinate information of view data and each object set up corresponding relation, then they are exported to three-dimensional depiction engine 3 (S3), thereby make display screen 51 demonstrate the image shown in view data.

On the other hand, if contain alternative OB (being "Yes" at S2) in view data, contents processing portion 2 makes the coordinate information of view data and each object set up corresponding relation, then they are exported to three-dimensional depiction engine 3, so that display screen 51 demonstrates the image shown in view data, and the coordinate information of alternative OB is exported to control part 7 (S4).

The region setting part 71 of control part 7 has been obtained the coordinate information of the alternative OB exporting from contents processing portion 2, according to this coordinate information, calculate for expanding the direction of expansion and the additional length that surveyed area A, wherein this additional length that is extensive magnitude AH, AW (S5).

Then, region setting part 71, according to extensive magnitude AH, the AW and the direction of expansion that calculate in S5, is set each alternative OB surveyed area A (S6) separately.Be specially, region setting part 71 is for the corresponding fundamental region A1 of the viewing area P1 of the alternative OB showing with display screen 51, and the extensive magnitude AH going out to prescribed direction additional calculations, AW, set surveyed area A thus.

If region setting part 71 has been set multiple surveyed area A to a unit image, judge whether adjacent surveyed area A has the part (S7) overlapping.If there is overlapping part (being "Yes" at S7) in surveyed area A, region setting part 71 resets surveyed area A, to eliminate this overlapping (S8).Be specially, region setting part 71 carries out following setting to surveyed area A again: make the wherein at least one party's of the surveyed area A overlapping each other surveyed area A, towards moving away from the direction of other surveyed areas A, so that surveyed area A is no longer overlapping each other.

Then, layout changing portion 74 changes the layout (S9) of the alternative OB that display screen 51 shows.Be specially, the coordinate information of the surveyed area A that layout changing portion 74 resets according to region setting part 71, generate in order to the control signal that the display position in display screen 51 changes to corresponding alternative OB, and this control signal is exported to contents processing portion 2.Contents processing portion 2 has obtained the control signal of exporting from layout changing portion 74, changes the former coordinate information of alternative OB into coordinate information shown in this control signal, then this coordinate information is exported to three-dimensional depiction engine 3.Thus, new settings that can corresponding surveyed area A, the image after the layout that makes display screen 51 demonstrate alternative OB is changed.

On the other hand, if there is no overlapping part (being "No" at S7) in surveyed area A, region setting part 71 does not carry out the processing of step S8 and S9.

Then, the coordinate figure of the coordinate informations of the surveyed area A that 72 references of selection judging part are exported from region setting part 71 and the expression user contact position of exporting from coordinate calculating part 6, judges whether alternative OB is selected (S10).Be specially, select judging part 72 from coordinate calculating part 6 has been obtained the coordinate figure that represents user's contact position, whether the coordinate figure that judges this user's contact position is included in the coordinate domain of the surveyed area A that region setting part 71 sets.

If the coordinate figure of contact position is not included in the coordinate domain interior (being "No" at S10) of surveyed area A, selects judging part 72 to be judged as without any alternative OB selected, and repeat the processing of S10, until there is alternative OB selected.On the other hand, if the coordinate figure of contact position is included in the coordinate domain interior (being "Yes" at S10) of surveyed area A, select judging part 72 to be judged as the alternative OB corresponding with this surveyed area A selected.Then, select judging part 72 to generate to express the selecteed control signal of this alternative OB, and this control signal is exported to contents processing portion 2.

Contents processing portion 2 has obtained the control signal of exporting from selection judging part 72, and the input operation of having done with regard to the alternative OB shown in this control signal in accordance with user, carries out the picture material processing (S11) corresponding with this input operation.

Like this, even if user's contact position departs from from the viewing area P1 of alternative OB, also can detect the input operation that user does alternative OA by processing example 1.In addition, can detect effectively the input operation that user carries out alternative, thereby prevent the misoperation of 3 d display device 1.

< processing example 2>

Another processing example 2 of the 3 d display device 1 of present embodiment is described with reference to Fig. 6 below.In processing example 2, will the processing in following situation be described.This situation is: after user's input operation, then carry out next input operation with same display frame request user.

Fig. 6 is the process flow diagram of the processing example 2 of the 3 d display device 1 in present embodiment.As shown in Figure 6, processing example 2 has step S21～S30.The processing of step S21～27 is identical with the processing of the step S1～S6 shown in Fig. 5 and S10, therefore in this description will be omitted.

At S27, if the coordinate figure of user's contact position is included in the coordinate domain interior (being "Yes" at S27) of surveyed area A, select judging part 72 to be judged as the alternative OB corresponding with this surveyed area A selected.Then, select judging part 72 to generate to express the selecteed control signal of this alternative OB, and this control signal is exported to contents processing portion 2.

Contents processing portion 2, from selecting judging part 72 to obtain in order to express the selecteed above-mentioned control signal of alternative OB, judges whether to ask user to proceed next input operation (S28) with same display frame.

If desired ask user to proceed next input operation (being "Yes" at S28), the coordinate information of the alternative OB that contents processing portion 2 has been selected to grand output adjustment part 73 output.

Grand output adjustment part 73 obtained export from contents processing portion 2 the coordinate information of selecteed alternative OB, change the coordinate information of this alternative OB, to reduce the grand output of this alternative OB, and the coordinate information after changing is exported to contents processing portion 2 (S29).

Contents processing portion 2 has obtained from grand output adjustment part 73 and has exported control signal, and the coordinate information after changing is exported to three-dimensional depiction engine 3, so that display screen 51 demonstrates the image after the grand output of selected alternative OB is reduced.Contents processing portion 2 also exports to control part 7 by the coordinate information after the change of this alternative OB so that control part 7 reset out with reduce after the surveyed area (S24) that matches of grand output.

On the other hand, if then carry out next input operation (being "No" at S28) without request user, contents processing portion 2 is same with the step S11 shown in Fig. 5, the input operation of just selecting the alternative OB shown in control signal that judging part 72 exports to do in accordance with user, carries out the picture material processing (S30) corresponding with this input operation.

Like this, by processing example 2, user can, from visually distinguishing the alternative OB and the unselected alternative OB that have selected, therefore can improve user's visibility and operability.

< sums up >

As mentioned above, the control part 7 of present embodiment is for 3 d display device 1, and 3 d display device 1 has the input display 5 that the input operation that not only detects user can also show alternative OB.Control part 7 possesses region setting part 71, and region setting part 71 is expanded into surveyed area larger than the viewing area P1 of alternative OB, and this surveyed area is used for detecting this user's input operation that the alternative OB to showing on input display 5 elects.

In addition, described above, in the prior art, the viewing area P1 of alternative OB showing on input display 5 and the alternative OB's of user's visual cognition can be inconsistent depending on recognizing position P2, thereby user's contact position departs from the viewing area P1 of alternative OB on input display 5 sometimes.

For this problem, the control part 7 of present embodiment possesses region setting part 71, region setting part 71 is set out the surveyed area A larger than the viewing area P1 of alternative OB, and this surveyed area A is used for detecting: this input operation that user elects to the alternative OB showing on input display 5.

; the control part 7 of present embodiment is set out the surveyed area A larger than viewing area P1; thus, even if user's contact position departs from the viewing area P1 of alternative OB on input display 5, the input operation that user does alternative OB still can be detected.

Therefore,, by the control part 7 of present embodiment, can prevent that user from making maloperation to the alternative OB of stereo display on 3 d display device 1, thereby can improve the operability of 3 d display device 1.

(embodiment 2)

Below, according to Fig. 7 and Fig. 8, the 2nd embodiment that relates to surveyed area expansion instrument of the present invention is described.

For convenience of explanation, for above-mentioned embodiment 1 in the accompanying drawing that illustrated parts there are the parts of same function, give same mark and the description thereof will be omitted.

The structure > of < 3 d display device

First, the structure of the 3 d display device of present embodiment is described with reference to Fig. 7.

Fig. 7 is the schematic configuration block diagram of the 3 d display device 1a in present embodiment.As shown in Figure 7,3 d display device 1a is in also having possessed image pickup part 75, position detection part 76, operational part (computing unit) 77 from the different of 3 d display device 1 of embodiment 1.

< image pickup part 75>

Image pickup part 75 is for example CCD (Charge Coupled Device: charge coupled device) or CMOS (Complementary Metal Oxide Semiconductor: complementary metal oxide semiconductor) camera, the front of its display screen 51 to 3 d display device 1a is taken, and the view data of shooting is exported to control part 7.The installation position of image pickup part 75 is not particularly limited, and can make the user's who operates 3 d display device 1a face fall into the position in image pickup scope but need to be installed in.In the present embodiment, image pickup part 75 is installed on input display 5 according to its lens axis mode vertical with display screen 51.The view data that image pickup part 75 photographs, the position detection part 76 that is used to possess for control part 7 carries out Check processing to the position of eyes of user.

< position detection part >

Position detection part 76 is in order to detect the position of eyes of user in the vertical direction of display screen 51.Be specially, position detection part 76 is analyzed the view data of exporting from image pickup part 75, detects thus the position of eyes of user contained in this view data.For example, position detection part 76 extracts the image-region that approaches people's colour of skin from view data, and from this image-region, finds out the region of eye feature amount more than defined threshold, and this region is identified as to the position of eyes of user.

Position detection part 76 by detect, eyes of user is with respect to the position of display screen 51, exports to operational part 77.At this, position detection part 76 can be according to eyes of user the position with respect to display screen 51, calculate the coordinate figure corresponding with eyes of user position on display screen 51, and this coordinate figure exported to operational part 77.In this scheme, position detection part 76 for example can use the conversion table that carries out coordinate figure conversion between image pickup part 75 and display screen 51, calculates the coordinate figure corresponding with eyes of user position on display screen 51.

< operational part >

The vertical projection of the alternative OB position of operational part 77 vertical projection on display screen 51 and user's visual recognition for eyes of user position on display screen 51, by the distance between these two vertical projections, be converted into the distance on distance and the transverse direction on longitudinal direction.At this, longitudinal direction is to delimit along the short transverse of display screen 51, and transverse direction is to delimit along the Width of display screen 51.

That is to say, the short transverse of display screen 51 delimited into y direction of principal axis (longitudinal direction), the Width of display screen 51 delimited into x direction of principal axis (transverse direction), when direction perpendicular to x axle and y axle delimited as z direction of principal axis (vertical direction), operational part 77 is in the space coordinates fixed by x axle, y axle, z axle, by the y axial coordinate of eyes of user position and alternative OB depending on recognizing poor between the y axial coordinate of position P2, calculate as longitudinal direction distance; And by the x axial coordinate of eyes of user position and this depending on recognizing poor between the x axial coordinate of position P2, calculate as transverse direction distance.

Fig. 8 is the mode chart of the routine computing method longitudinal direction distance H calculated for the operational part 77 shown in key diagram 7.

Below the computing method of longitudinal direction distance H are described.As for the computing method of transverse direction distance W (without diagram), as long as being considered as to x direction of principal axis, y direction of principal axis can similarly calculate.The computing method of transverse direction distance W that therefore description thereof is omitted.

In Fig. 8, L represents the distance (unit is mm) between display screen 51 and eyes of user, R represents the optical axis of image pickup part 75 and through display screen 51 centers and perpendicular to the distance the vertical line of display screen 51 (unit is mm), α represents the visual angle of image pickup part 75, the longitudinal direction length (unit is mm) of the display screen 51 when SH representative delimited as longitudinal direction by the short transverse of input display 5.

In addition, the distance L between display screen 51 and eyes of user can be for example: the mean value of the spacing between the spacing between display screen 51 and user's right eye and display screen 51 and user's left eye.Or can be also the spacing of one party in display screen 51 and right and left eyes.

At this, if the pixel count on the longitudinal direction of display screen 51 is made as to 2Y ₁, the y coordinate depending on recognizing position P2 is made as to y ₁, the y coordinate of eyes is made as to y ₂, the pixel count on the longitudinal direction of image pickup part 75 is made as to 2Y ₂, the centre coordinate value of display screen 51 is made as to (0,0), the visual angle between the axis of image pickup part 75 and distance L (sight line) (h1 in figure) is (y ₂/ Y ₂) × L × tan (α/2), the y coordinate (h2 in figure) of alternative OB in space coordinates is (y ₁/ Y ₁) × (SH/2).

Therefore, the y coordinate of eye position in space coordinates is (y ₂/ Y ₂) × L × tan (α/2)+R.

Thereby can calculate longitudinal direction distance H is R-(y ₂/ Y ₂) × L × tan (α/2)-(y ₁/ Y ₁) × (SH/2).

The computing method of longitudinal direction distance H and transverse direction distance W are not limited to above-mentioned method, also can use other known methods.

< computing method 3>

The longitudinal direction extensive magnitude of surveyed area A is made as to AH (unit is mm), and region setting part 71 uses following calculating formula 3 to calculate longitudinal direction extensive magnitude AH.

AH[mm]=H × (h-d)/(L-d) [mm] ... (calculating formula 3)

Equally, the transverse direction extensive magnitude of surveyed area A is made as to AW (unit is mm), region setting part 71 uses following calculating formula 4 to calculate transverse direction extensive magnitude AW.

AW[mm]=W × (h-d)/(L-d) [mm] ... (calculating formula 4)

In above-mentioned calculating formula 3 and calculating formula 4, L is the distance (unit is mm) between display screen 51 and eyes of user, h be alternative OB visually from display screen 51 grand go out grand output (unit is mm), d is to the distance (unit is mm) for detecting till the position of user input operation from display screen 51, H is the longitudinal direction distance (unit is mm) that operational part 77 calculates, and W is the transverse direction distance (unit is mm) that operational part 77 calculates.

As mentioned above, in the calculating formula 1 and calculating formula 2 described in embodiment 1, the longitudinal direction distance H that region setting part 71 use operational parts 77 calculate and transverse direction distance W replace longitudinal direction length SH and the transverse direction length SW of display screen 51, and calculate extensive magnitude AH, the AW of surveyed area A.Therefore region setting part 71 can be set needed surveyed area A with the position of eyes of user.

Thus, appropriately set the surveyed area A corresponding with eyes of user position by the 3 d display device 1a of present embodiment, can effectively prevent user's maloperation.
