Embodiment

Below, according to Fig. 1～Figure 25 execution mode of the present invention is described.

(stereopsis watch principle)

Explain at first how the beholder sees stereopsis.

What Fig. 1 represented is the principle of seeing stereopsis.State when Fig. 2 and Fig. 3 have represented to see 2 nonoverlapping stereopsis respectively.Fig. 4 representes is the state when seeing 2 overlapping stereopsis.

As shown in Figure 1, the beholder is just from the position screen (display surface of the display unit of afterwards stating 10 (with reference to Fig. 7)) of left eye L and right eye R.In screen; Left eye is presented at left eye L side with anaglyph L1, and right eye is presented at right eye R side with anaglyph R1, under this state; Beholder's sight line (dotted line among the figure) just drops on anaglyph L1, R1 is last, just sees the stereopsis D1 that is in the screen rear side seemingly thus.In addition, in screen, right eye is presented at left eye L side with anaglyph R2; Left eye is presented at right eye R side with anaglyph L2; Under this state, beholder's sight line (chain-dotted line among the figure) drops on anaglyph L2 after intersecting, R2 is last, just sees the stereopsis D2 that is in the screen front side seemingly thus.In addition; Right eye is presented on the same position in the screen with anaglyph L3 with anaglyph R3 and left eye; Under this state; Beholder's sight line (dotted line among the figure) drops on anaglyph L3, R3 is last, and the stereopsis D3 that is seen thus just is in the display position of anaglyph L3 and R3 in the screen.

In following explanation, represent left eye to use anaglyph with label L 1, L2, represent right eye to use anaglyph with mark R1, R2.

Describe in the face of example shown in Figure 2 down.In screen, anaglyph L1, R1 are presented on the same position (parallax is zero), and anaglyph L2, R2 are presented on the other same position different with anaglyph L1, R1 (parallax is zero).Under this state, the stereopsis D1 that the beholder sees just is on the display position of anaglyph L1, R1, and the stereopsis D2 that is seen just is on the display position of anaglyph L2, R2.Stereopsis D1, D2 that this moment, the beholder saw are not overlapping on screen.

Describe in the face of example shown in Figure 3 down.In screen, anaglyph L1 is presented at right eye R side, and anaglyph R1 is presented at and is positioned at left eye L side and leaves on the position of anaglyph L1.In addition, in screen, anaglyph L2, R2 are presented on the same position near anaglyph R1 right side.Under this state, the stereopsis D1 that the beholder saw just seem the centre position that is in anaglyph L1 and R1 just look at seemingly be in face of, and three-dimensional image D2 seems the display position that is in anaglyph L2 and R2.Therefore, this moment, the beholder saw stereopsis D1, D2 are not overlapping.

In example shown in Figure 4, the center line (y axle) at the center of normal to screen left and right directions axle (x axle) passes the centre position of left eye L and right eye R.In this example, in screen, anaglyph L1 and anaglyph R1 are presented at right eye R side and left eye L side respectively facing to center line and with equally spaced mode.In addition, in screen, anaglyph L2, R2 are presented on the centre position (intersection point of x axle and y axle) of anaglyph L1 and R2.Under this state, the stereopsis D1 that the beholder sees seems on the center line that is in the centre position of passing anaglyph L1 and R1, just looks at the place ahead that seemingly is in screen.The stereopsis D2 that is seen seems (on the screen) on the display position that is in anaglyph L2, R2.Therefore, this moment, the beholder saw stereopsis D1, D2 overlap on the center line.

In example shown in Figure 5, the display position of anaglyph L1, R1 and anaglyph L2, R2 is identical with the illustrative display position of Fig. 4.But the difference of the example of Fig. 5 and the example of Fig. 4 is that the beholder is anaglyph L1, R1 and anaglyph L2, R2 from the center line right side.Under this state, the stereopsis D1 that the beholder sees seems and is in: on the line (dotted line among the figure) in the centre position of connection anaglyph L1 and R1 and two centre positions of left eye L and right eye R.Therefore, this moment, the beholder saw stereopsis D1, D2 overlap on the above-mentioned line.

Describe in the face of example shown in Figure 6 down.In screen, anaglyph L1, L2 are presented at right eye R side, and anaglyph R1, R2 are presented at left eye L side.In addition, anaglyph L1, R1 and anaglyph L2, R2 dispose facing to center line and with equally spaced mode, but anaglyph L2, R2 are configured in than on anaglyph L1, the position of R1 away from center line.Under this state, the stereopsis D1 that the beholder sees seem be in just look on the center line seemingly be in face of, stereopsis D2 also seem be in just look on the center line like more near in face of.

Like this; In the example of Fig. 4 and even Fig. 6; The centre position of the centre position of anaglyph L1 and R1 and anaglyph L2 and R2 has taken place overlapping, so stereopsis D1, D2 that the beholder sees seem on the line that overlaps two centre positions that connect above-mentioned centre position and left eye L and right eye R.As long as the display position to the display position of anaglyph L1, R1 and anaglyph L2, R2 is set; So that the centre position of anaglyph L1 and R1 no longer overlaps with the centre position of anaglyph L2 and R2, the stereopsis D1 that then beholder saw, D2 are just not overlapping.

In following explanation, above-mentioned centre position is called mean place.

(structure of control part)

Control part 2 has the function of the following stated, thereby can do appropriate stereo display to adjacent literal shape object.

(1) mean place adjustment function

Mean place between mean place between 2 couples of anaglyph L1 of control part and R1 (the 1st anaglyph) and anaglyph L1 and L2 (the 2nd anaglyph) is adjusted, so that this two mean places non-overlapping copies (making the stereopsis non-overlapping copies of literal shape object).

(2) grand output difference adjustment function

Grand output difference between the stereopsis of 2 pairs of ambiguous 2 literal shape objects of control part is adjusted, so that their stereopsis is no longer fuzzy.

(3) adjustment function in the viewing area

2 pairs of above-mentioned two mean places of control part and/or above-mentioned grand output are adjusted, and the stereopsis of literal shape object can not overlapped in aforesaid literal viewing area.

(4) enlarge adjustment function in the viewing area

2 pairs of above-mentioned two mean places of control part and/or above-mentioned grand output are adjusted, and the stereopsis of literal shape object can not overlapped in the literal viewing area after expansion.At this, the literal viewing area after the expansion be under the prerequisite scope that does not overlap with non-legible shape object, enlarge and.

In order to realize these above-mentioned functions, control part 2 possesses has display position to set handling part 21, three-dimensional amount is set handling part 22, literal viewing area handling part 23, information retaining section 24.

< display position is set the structure of handling part >

Display position is set handling part 21 (display position setup unit) anaglyph L1, R1 and the anaglyph L2 of adjacent literal shape object, the display position of R2 is set, so that the literal shape object non-overlapping copies of stereo display.In order to set above-mentioned display position; Display position is set handling part 21 according to the literal shape object display message that obtains from content stores portion 31; Mean place between the mean place between anaglyph L1 and R1 and anaglyph L2 and R2 is adjusted, so that two mean place non-overlapping copies.To this, display position is set handling part 21 and is specifically had following technical pattern.

(1) mean place adjustment function

(1-1) mean value calculation is handled

Display position is set handling part 21 according to the display position of anaglyph L1 and R1 and the display position of anaglyph L2 and R2, according to following scheme each mean place is calculated.That is, be the origin of coordinates with screen center's (intersection point of x axle and y axle), the initial point right side is made as the positive coordinate territory, the initial point left side is made as the negative coordinate territory.Average coordinates between the left end coordinate of display position setting handling part 21 calculating anaglyph L1 and the left end coordinate of anaglyph R1; And calculate the average coordinates between the right-hand member coordinate of right-hand member coordinate and anaglyph R1 of anaglyph L1, then with the interval range between these two average coordinates as mean place.Equally; Average coordinates between the left end coordinate of display position setting handling part 21 calculating anaglyph L2 and the left end coordinate of anaglyph R2; And calculate the average coordinates between the right-hand member coordinate of right-hand member coordinate and anaglyph R2 of anaglyph L2, then with the interval range between these two average coordinates as mean place.

(1-2) compare judgment processing

Display position is set handling part 21 and is judged whether two mean places of aforementioned calculation overlap.Be specially; Display position set handling part 21 with one of them mean place (interval range that is defined by left end average coordinates and right-hand member average coordinates) as benchmark; Average coordinates is compared, thereby judge as whether having confession in the mean place of benchmark and define wherein at least one side of the left end average coordinates and the right-hand member average coordinates of another mean place.

At this, display position set handling part 21 with the mean place between the mean place between anaglyph L1 and R1 and anaglyph L2 and R2 respectively as benchmark, thereby carry out 2 above-mentioned judgements.Be specially; If with the mean place between anaglyph L1 and R1 is benchmark, then display position setting handling part 21 judges in this mean place whether exist: wherein at least one side of left end average coordinates between anaglyph L2 and R2 on the mean place and right-hand member average coordinates.In addition; If with the mean place between anaglyph L2 and R2 is benchmark, then display position setting handling part 21 judges in this mean place whether exist: wherein at least one side of left end average coordinates between anaglyph L1 and R1 on the mean place and right-hand member average coordinates.Like this, the mean place between the mean place between anaglyph L1 and R1 and anaglyph L2 and R2 is carried out above-mentioned judgement as benchmark respectively, can judge fully thus whether two mean places have overlapping.That why carries out judging for 2 times the reasons are as follows.

If have left end average coordinates and this two side of right-hand member average coordinates of another mean place in a certain mean place; Then said another mean place is overlapping fully with respect to said a certain mean place, and the scope that is therefore defined by said left end average coordinates and right-hand member average coordinates just is equivalent to the overlapping scope of two mean places.Therefore, be enough to judge the overlapping situation of two mean places this moment.

Yet; In a certain mean place, have left end average coordinates and this two side of right-hand member average coordinates of another mean place; But when not having left end average coordinates and the right-hand member average coordinates of said a certain mean place in said another mean place, then be not enough to judge the overlapping situation of two mean places.In this case, if said another mean place becomes benchmark, then just there be not left end and the right-hand member that is defining said a certain mean place in this another mean place.So, although said another mean place is overlapping fully with respect to said a certain mean place, also can by erroneous judgement be broken into do not have overlapping.

To this, said a certain mean place is also carried out same judgement as benchmark, whether just can judge two mean places thus has overlapping.

In addition, for example when the left side of the mean place between anaglyph L1 and R1, and anaglyph L2 and R2 between the right side of mean place part property takes place when overlapping, then only judge it is inadequate as benchmark with the mean place between anaglyph L1 and R1.Its reason is; Only can judge that the right-hand member average coordinates on the mean place is in the mean place between anaglyph L1 and R1 between anaglyph L2 and R2 this moment, yet the left end average coordinates on the mean place and right-hand member average coordinates are unknown with respect to the relation of mean place between anaglyph L2 and R2 between anaglyph L1 and R1.Therefore, be the overlapping scope that can't be specific goes out two mean places under above-mentioned situation.

To this, further carry out above-mentioned judgement with the mean place between anaglyph L2 and R2 as benchmark, thereby judge whether the left end average coordinates on the mean place between anaglyph L1 and R1 is in the mean place between anaglyph L2 and R2.By the scope that the left end coordinate on the mean place between the right-hand member average coordinates on the mean place between above-mentioned anaglyph L2 that judges and R2 and anaglyph L1 and R1 is defined, be the overlapping scope of two mean places.

(1-3) the mean place change is handled

Display position is set handling part 21 and is equipped with when overlapping judging two average bit, just changes the display position of anaglyph, to eliminate overlapping between two mean places.Be specially; The mean place (benchmark mean place) that keeps being used as in the above-mentioned judgement side of benchmark immobilizes; Make the display position of the anaglyph of another mean place as comparison other (relatively mean place) then, be shifted with the distance (this distance equals above-mentioned overlapping scope at least) and the direction that the comparison mean place is departed from from the scope of benchmark mean place.Or display position setting handling part 21 also can be kept said relatively mean place and immobilize, and according to above-mentioned same method the anaglyph of said benchmark mean place is shifted then.

Display position is set handling part 21 keeping the constant at interval mode of two anaglyphs, and the display position of this two anaglyph is shifted.Its reason is, as after state, if change the interval of two anaglyphs, just grand output can change (function that three-dimensional amount is set handling part 22).Therefore, it is under the prerequisite that does not change grand output that display position is set handling part 21, change the display position of two anaglyphs according to such scheme, changes mean place thus.

Like this, display position is set handling part 21 in order to realizing mean place adjustment function, and its display position to the display position of anaglyph L1, R1 and anaglyph L2, R2 is set, so that mean place is no longer overlapping.

(1-4) mean place of the anaglyph of adjacent literal shape object adjustment on above-below direction

More than, be object to go up adjacent anaglyph L1, R2 and anaglyph L2, R2 at left and right directions coordinate domain (x axle), to above-mentioned mean value calculation handle, relatively judgment processing, mean place change are handled and are illustrated.But, also can use above-mentioned each to handle the mean place of adjusting them about 2 groups of anaglyphs of adjacency on above-below direction.

Therefore, display position is set handling part 21 in the above-mentioned former above-below direction coordinate domain of lighting (coordinate domain that is made up of x axle and y axle), carries out above-mentioned each processing.In those are handled, for the anaglyph of narration in the aforementioned reason, " right side " and " left side " replacement is expressed as " on " and D score.Display position is set handling part 21 and especially according to following mode 2 groups of anaglyphs of adjacency is up and down compared judgment processing.

If the mean place with one group of anaglyph of upside is a benchmark, then display position is set handling part 21 and is judged upper end average coordinates and wherein at least one side of lower end average coordinates on the mean place of the one group of anaglyph that whether has downside in this mean place.In addition; If the mean place with one group of anaglyph of downside is a benchmark, then display position is set handling part 21 and is judged upper end average coordinates and wherein at least one side of lower end average coordinates on the mean place of the one group of anaglyph that whether has upside in this mean place.

At this, can see stereopsis in order to make the beholder, need the straight line line direction of 2 same image (parallax image) along beholder's right and left eyes be configured on the diverse location.When the left and right directions (x direction) of screen is parallel with above-mentioned straight line line (beholder's face do not have tilt and face screen), if anaglyph is by 2 image constructions that are arranged above and below, then the beholder can't be through this anaglyph stereopsis.Therefore, in this execution mode, facing screen with the beholder is prerequisite, and anaglyph by about 2 image constructions of arranging.

(2) mean place adjustment function in the zone

Display position is set handling part 21 is not causing literal shape object to run off under the prerequisite of literal viewing area, in the literal viewing area, carries out above-mentioned mean place change and handles.Therefore, display position setting handling part 21 indication literal viewing area handling parts 23 judge whether the stereopsis of literal shape object is in the literal viewing area.If literal viewing area handling part 23 is judged stereopsis not in the literal viewing area, display position is set the change processing that handling part 21 just averages the position, till literal viewing area handling part 23 judges that stereopsis are in the literal viewing area.So, display position is set and is adjusted function in the handling part 21 realization viewing areas and enlarge adjustment function in the viewing area.

< three-dimensional amount is set the technical pattern of handling part >

(1) grand output adjustment function

(1-1) basic value is set and is handled

Three-dimensional amount is set handling part 22 (three-dimensional amount adjustment unit) according to the literal shape object display message that obtains from content stores portion 31, sets the basic grand output (basic value) of literal shape object when stereo display.For setting the basic value of grand output, the solid amount is set the grand output that handling part 22 uses from operating portion 5 inputs, or use is stored in the grand output typical set value in the standard setting storage part 32.Or three-dimensional amount sets that handling part 22 recognizes according to looking that condition information obtains that portion is 6 that obtain, two spacings of beholder and distance of visual cognition, sets the basic value of grand output.Wait and can know through Fig. 3, if variation has taken place for two spacings and distance of visual cognition, then the stereopsis seen of beholder also can change with respect to the position of screen.Therefore, when output is swelled in decision, need with reference to two spacings and distance of visual cognition at least.

(1-2) grand output adjustment is handled

Three-dimensional amount is set handling part 22 and is adjusted grand output according to above-mentioned basic value.Be specially, three-dimensional amount is set handling part 22 and is adjusted grand output through the interval of the anaglyph about adjusting.This is because the interval of anaglyph is narrow more, and grand output is just more little, and the interval of anaglyph is wide more, and grand output is big more cause just.Like this, three-dimensional amount is set handling part 22 and is adjusted grand output through the interval of adjustment anaglyph, thereby the display position of utilization anaglyph is set final grand output.

(2) grand output difference adjustment function

In order to prevent that two stereopsis from seeing smudgyly, three-dimensional amount set 22 pairs of handling parts wherein the grand output of at least one side's stereopsis adjust.Why two stereopsis can blur, be because two stereopsis on the x direction near and the excessive cause of difference of grand output.To this; If two stereopsis edge is parallel to the left and right directions (x direction of principal axis) of screen cover near arriving below the given interval; And the difference of the grand output of two stereopsis is more than set-point; Then three-dimensional amount set 22 pairs of handling parts wherein the grand output of at least one side's stereopsis adjust so that the difference of the grand output of two stereopsis is lower than set-point.Therefore; Three-dimensional amount is set handling part 22 and is judged that two stereopsis are whether more than given away from each other interval on the x direction of principal axis; If judged result is two stereopsis closer to each other to below the given interval on the x direction of principal axis, whether the difference of grand output of then then judging this two stereopsis is more than set-point.

Above-mentioned given interval is meant: though the difference of the grand output of two stereopsis more than set-point, this two stereopsis also can not see fuzzyly institute by predefined maximum range value.In addition, above-mentioned set-point is meant: can not cause institute that stereopsis sees fuzzyly by predefined grand output maximum difference.Like this, the grand output adjustment of three-dimensional amount setting handling part 22 realizations function.

(3) grand output adjustment function in the zone

Three-dimensional amount is set handling part 22 (three-dimensional amount setup unit) is not causing literal shape object to run off under the prerequisite of literal viewing area, the above-mentioned grand output of change setting in the literal viewing area.Therefore, three-dimensional amount setting handling part 22 indication literal viewing area handling parts 23 judge whether the stereopsis of literal shape object is in the literal viewing area.If the judged result of literal viewing area handling part 23 is that stereopsis is not in the literal viewing area; Three-dimensional amount is set handling part 22 and just swell the change processing of output, is judged as till stereopsis is in the literal viewing area up to literal viewing area handling part 23.Like this, three-dimensional amount is set and is adjusted function in the handling part 22 realization viewing areas and enlarge adjustment function in the viewing area, and sets grand output.

< technical pattern of literal viewing area handling part >

Literal viewing area handling part 23 (region decision unit) judges whether the stereopsis of literal shape object is in (region decision processing) in its literal viewing area after having received the indication from display position setting handling part 21 and three-dimensional amount setting handling part 22.Therefore, the position that literal viewing area handling part 23 calculates stereopsis according to the position of the right and left eyes anaglyph of literal shape object, and judge whether this position of calculating is within the profile scope of this literal viewing area.In addition, same judgement is also carried out in the literal viewing area after the expansion stated after also being directed against of literal viewing area handling part 23.

Can literal viewing area handling part 23 (expansion could judging unit) is judged enlarge literal viewing area (expansion could judgment processing) under the prerequisite that does not overlap with non-legible shape object.Therefore, if the profile scope of the profile scope of literal viewing area and non-legible object is given more than the set a distance away from each other, then literal viewing area handling part 23 is judged as and can enlarges, otherwise, then be judged as and can not enlarge.In addition, literal viewing area handling part 23 (literal viewing area enlarge unit) is being judged as can enlarge the literal viewing area time, the literal viewing area is expanded to (the expansion processing of literal viewing area) till the scope that can enlarge.

Literal viewing area handling part 23 through carry out judgment processing inside and outside the above-mentioned literal viewing area, enlarging could judgment processing, the literal viewing area enlarges and handles, come to set handling part 21 and three-dimensional amount and set handling part 22 and together realize adjustment function in adjustment function and the expansion viewing area the viewing area in display position.

< display position is set the collaboration process of handling part and three-dimensional amount setting handling part >

Adjustment function and enlarge adjustment function in the viewing area and can either realize through the assembled scheme that display position is set handling part 21 and literal viewing area handling part 23 in the viewing area also can realize through the assembled scheme that the solid amount is set handling part 22 and literal viewing area handling part 23.But if only use a kind of assembled scheme, then might adjust the position of stereopsis rightly, therefore preferred two kinds of assembled schemes and usefulness.

For example, set handling part 21 by display position earlier and change the anaglyph display position, to eliminate the overlapping of stereopsis as much as possible, the anaglyph display position after will changing then sends to three-dimensional amount and sets handling part 22.Three-dimensional amount is set handling part 22 and on the basis of this display position, is adjusted display position, to reduce grand output, then the overlapping display position that has been able to eliminate between stereopsis is set at end value (finally grand output).Or, also can set handling part 22 by the solid amount earlier and adjust grand output, set the display position that handling part 21 is adjusted anaglyph by display position thereafter.Through like this, meticulousr adjustment is done in position that just can the stereo image.

< technical pattern of information retaining section >

The display position of the anaglyph L1 that 24 pairs of display positions settings of information retaining section handling part 21 sets, the display position of R1 and anaglyph L2, R2 is preserved.In addition, information retaining section 24 is also preserved three-dimensional amount and is set the grand output that handling part 22 sets.The dimension information of the literal viewing area that information retaining section 24 preservation literal viewing area handling parts 23 are enlarged.Information retaining section 24 as the information that supplies to generate anaglyph, sends to anaglyph generation portion 7 with the information of these preservations.

[action of anaglyph generating apparatus]

Below the action (anaglyph generation method) of anaglyph generating apparatus 1 with above-mentioned technical pattern is described.

In following explanation, for ease, sometimes " literal shape object " abbreviated as " literal ".

(mean place adjustment function)

Fig. 9 is that anaglyph generating apparatus 1 is for realizing the flow chart of the action that mean place adjustment function is carried out.

As shown in Figure 9, at first, control part 2 is obtained literal shape object display message (step S101).At this moment, control part 2 both can directly have been obtained the literal shape object display message that is stored in the content stores portion 31, also can obtain literal shape object display message through the content of storage in the content storage part 31 is carried out graphical analysis.

Secondly, the grand output of 22 pairs of given literal of three-dimensional amount setting handling part is set (step S102).At this moment, it is basic value with the grand output through operating portion 5 inputs that three-dimensional amount is set handling part 22, and sets grand output according to this basic value.Or three-dimensional amount is set handling part 22 is set grand output according to the grand output of the standard of storage in the standard setting storage part 32 basic value.Or three-dimensional amount is set handling part 22 and is recognized condition information (two spacing and distance of visual cognition) according to looking of beholder and set grand output.

When output was swelled in setting, the literal of the stereo display of was big more, or the 2D display text around the literal of the stereo display of wanting is big more, and three-dimensional amount setting handling part 22 is just set its grand output more bigly.

Then, display position is set handling part 21 to 2 adjacent literal, mean place between calculating anaglyph L1 and R1 and the mean place (step S103) between anaglyph L2 and R2, and judge whether these two mean places have overlapping (step S104).At this moment, display position set handling part 21 with two sides' literal respectively as benchmark, whether the mean place of calculating anaglyph and two mean places that judgement is calculated have overlapping.

In step S104; Be equipped with overlapping (" denying ") if be judged as average bit; Then display position is set the display position of handling part 21 adjustment anaglyphs, so that two mean places are separated from each other (step S105), judges then whether adjusted two mean places have overlapping (step S106).At this moment, display position is set handling part 21 for example with the mode at the interval of keeping the horizontal parallax image, with anaglyph L1, R1 or anaglyph L2, R2 to left or right-hand moving.Thus, on the basis that does not change grand output, only adjust mean place.

In step S106; If be judged as mean place zero lap (" being "); Then the literal shape object display message in 21 pairs of information retaining section 24 of display position setting handling part is upgraded, so that the display position of above-mentioned adjusted anaglyph is included in the literal shape object display message (step S107).Above-mentioned steps S101～S107 has constituted display position and has set step.Then, anaglyph generation portion 7 generates anaglyph (step S108 according to the literal shape object display message after upgrading; Anaglyph generation step), and with the anaglyph that generates send to display unit 10 (step S109).

In addition, in step S104,, then handle and advance to step S108 if be judged as mean place zero lap (" being ").

At this, the adjustment example of the display position of the adjustment example of the display position of anaglyph L1, R1 and anaglyph L2, R2 is described.What Figure 10 and Figure 11 represented is the stereopsis position of the non-overlapping anaglyph of mean place.

In example shown in Figure 10, anaglyph L1 is presented at right eye R side, and anaglyph R1 is presented at left eye L side, and the mean place between anaglyph L1 and R1 is on the center line (y axle).In addition, anaglyph L2, R2 are presented on the same position in anaglyph R1 left side.

Imagination is before being adjusted to state shown in Figure 10, and the average bit between the mean place between anaglyph L2 and R2 and anaglyph L1 and R1 is equipped with overlapping.Under this overlap condition, the anaglyph L1 that the beholder saw, the stereopsis of R1 just can overlap on the center line with the stereopsis of anaglyph L2, R2.

To this, adjust to anaglyph R1 left side shown in Figure 10 if the display position of anaglyph L2, R2 moved, then the mean place between the mean place between anaglyph L1 and R1 and anaglyph L2 and R2 is just no longer overlapping.Thus, the stereo-picture D1 that the beholder sees (the 1st stereopsis) appears on the center line and swells, and the stereo-picture D2 that is seen (the 2nd stereopsis) is in the position in anaglyph R1 left side.

On the other hand, in example shown in Figure 11, anaglyph L1, L2 are presented at right eye R side, and anaglyph R1, R2 are presented at left eye L side.In addition, anaglyph L1, R1 are in along center line (y axle) roughly on the position of symmetry, so the mean place between anaglyph L1, R1 roughly is positioned on the center line (y axle).In addition, anaglyph L2 is in the left side of anaglyph L1, and anaglyph R2 is in the left side of anaglyph R1.

Imagination is before being adjusted to state shown in Figure 11, and anaglyph R2 for example is in the right side of anaglyph R1, and anaglyph L2 is roughly identical with the mean place between anaglyph L1 and R1 with mean place between R2.Under this state, the anaglyph L1 that the beholder saw, the stereopsis of R1 just can roughly overlap on the center line with the stereopsis of anaglyph L2, R2.

To this, adjust to anaglyph R1 left side shown in Figure 11 if the display position of anaglyph R2 moved, then the mean place between the mean place between anaglyph L1 and R1 and anaglyph L2 and R2 is just no longer overlapping.Thus, the stereopsis D1 that the beholder sees just appears on the center line and swells, and the left side that three-dimensional image D2 appears in stereopsis D1 swells.

At this, explain according to such scheme and adjusted the display effect behind the anaglyph display position.What Figure 12 represented is the display frame 101 when coming display text with the 2D mode.Figure 13 representes is the literal of stereo display and the display frame 102 when literal overlaps around it.Figure 14 representes is no longer display frame 103 when overlapping with literal around it of literal of stereo display.

In display frame shown in Figure 12 101, character image 202 all shows with the 2D mode with literal.In this display frame 101, be presented at the left side of character image 202 according to the mode of two row by the text line 201 that " A "～" J " forms." K "～" O " is presented at picture top." K "～" O " is though upward additional have shade, and this is not stereo display, but shows to simulate three-dimensional mode.

In display frame shown in Figure 13 102, " C " in the text line 201 swells for stereo display seems.In this case, as far as the beholder, " C " that is seen just with " B " that be adjacent to " C ", " D " reaches " H " has overlapping.At this moment, for example the anaglyph L2 of the anaglyph L1 of " C ", R1 and " B ", the relation of the position between the R2 just are similar to situation shown in Figure 4.But the display position of " B " is positioned at the left side of the display position of " C ", and therefore " B " is the equal of that the display position of anaglyph L2 shown in Figure 4, R2 slightly has been partial to the situation behind the left side.

To this, display position is set handling part 21 and is moved according to aforesaid processing, makes the display position of anaglyph L2, the R2 of " B " be shifted to the left (for example Figure 10).Thus, the mean place between anaglyph L1 and R1 no longer and the mean place between anaglyph L2 and R2 overlapping, " C " that is seen and " B " be zero lap just.With " C " is that benchmark comes " D " and " H " also carried out above-mentioned processing, and is benchmark with respectively " B ", " D ", " H " also, to they separately the literal of institute's adjacency carry out above-mentioned processing.Thus, the literal in the text line 201 that the beholder saw is zero lap each other just as display frame 103 shown in Figure 14 just.

(grand output adjustment function)

Figure 15 representes is the position that this two stereopsis when fuzzy takes place 2 stereopsis.Figure 16 representes is the position of this two stereopsis of 2 stereopsis when fuzzy.

In example shown in Figure 15, the mean place zero lap between the mean place between anaglyph L1 and R1 and anaglyph L2 and R2.Therefore stereopsis D1 that the beholder saw and D2 be zero lap each other.Yet in this example, the solid amount difference d1 between stereopsis D1 and the D2 is bigger, so stereopsis D1, D2 that the beholder sees are smudgy.

To this, in example shown in Figure 16, three-dimensional amount is set the display position that handling part 22 changes anaglyph L2, R2, so that stereopsis D2 is in than stereopsis D2 shown in Figure 15 near the position in face of the beholder.Thus, the solid amount difference d2 between stereopsis D1 and the D2 (＜d1) just be lower than set-point, thus the beholder can clearly see unambiguous stereopsis D1, D2.

(adjustment function in the viewing area)

Figure 17 is that anaglyph generating apparatus 1 is for realizing the flow chart of the action that the adjustment function is carried out in the viewing area.

Shown in figure 17, at first, control part 2 is obtained literal shape object display message and literal display region information (step S201).At this moment, control part 2 is to carry out the processing identical with the abovementioned steps S101 shown in Fig. 9 to obtain literal shape object display message.In addition, control part 2 both can directly have been obtained the literal shape object display message that is stored in the content stores portion 31, also can obtain literal shape object display message through the content of storage in the content storage part 31 is carried out graphical analysis.

Secondly, the grand output of 22 pairs of given literal of three-dimensional amount setting handling part is set (step S202).At this moment, three-dimensional amount setting handling part 22 is to carry out the processing identical with abovementioned steps S102 to set grand output.

Then, display position is set handling part 21 and is carried out the processing identical with abovementioned steps S 103, to 2 literal of adjacency, calculates mean place and the mean place (step S203) between anaglyph L2 and R2 between anaglyph L1 and R1.Then, display position is set handling part 21 and is carried out the processing identical with abovementioned steps S104 to judge whether two mean places have overlapping, and literal viewing area handling part 23 judges whether the stereopsis of literal is in (step S204) in the literal viewing area.At this moment, literal viewing area handling part 23 is whether the stereopsis of judging literal is in the profile scope of literal viewing area.

In step S204; If it is overlapping that judged result is that average bit is equipped with; Or stereopsis not in its literal viewing area (" denying "), then display position is set display position and/or the grand output that handling part 21 and/or three-dimensional amount set 22 pairs of anaglyphs of handling part and is adjusted (step S205).At this moment, display position is set handling part 21 and is carried out the display position that anaglyph is adjusted in the processing identical with abovementioned steps S105, so that two mean places are separated from each other.In addition, three-dimensional amount is set handling part 22 to adjusting with the display position of the wherein at least one group of anaglyph of 2 corresponding 2 groups of anaglyphs of stereopsis, adjusts grand output with this.

Display position is set handling part 21 and literal viewing area handling part 23 carries out the processing identical with step S204, that is, judge through above-mentioned adjusted two mean places zero lap whether, and judge whether stereopsis is positioned at its literal viewing area (S206).At this, overlapping if judged result is that two average bit are equipped with, or stereopsis not in its literal viewing area (" denying "), then turn back to step S205.

In addition; In step S206; If judged result is that two mean place zero laps and stereopsis are in (" being ") its literal viewing area in, then the literal shape object display message set in handling part 21 and/or 22 pairs of information retaining section 24 of three-dimensional amount setting handling part of display position is upgraded (step S207).At this moment, display position is set handling part 21 and/or three-dimensional amount and is set handling part 22 display position and/or the grand output of adjusted anaglyph inserted in the literal shape object display message.

Thereafter, processing advances to step S108.In addition, in step S204,, then advance to step S108 if judged result is that mean place zero lap and stereopsis are in (" being ") in its literal viewing area.

At this, explain and in the literal viewing area, adjusted the display position of anaglyph and/or the grand output display effect afterwards of stereopsis according to such scheme.What Figure 18 represented is the display frame 104 when being presented at literal in the lines window with the 2D mode.What Figure 19 represented is, 1 literal of stereo display and literal display frame 105 in an overlapping time the in the lines window around it.What Figure 20 represented is, 1 literal of stereo display and literal display frame 106 during zero lap in the lines window around it.What Figure 21 represented is, 2 literal of stereo display and literal display frame 107 in an overlapping time the in the lines window around it.What Figure 22 represented is, 2 literal of stereo display and literal display frame 108 during zero lap in the lines window around it.

In display frame shown in Figure 180 104, character image 202 all shows with the 2D mode with literal.In this display frame 104, be presented in the lines window 203 (literal viewing area) that is arranged at character image 202 left sides according to two capable modes by the text line 201 that " A "～" J " forms.

In display frame shown in Figure 19 105, " C " in the text line 201 swells for stereo display seems.In this case, for the beholder, " C " that is seen reaches " H " in an overlapping with " B ", " D " that are adjacent to " C " in lines window 203.

To this, display position is set handling part 21 and is moved according to aforesaid processing, under the prerequisite within lines window 203 scopes, only the display position of anaglyph is adjusted.Thus, the literal in the text line 201 that the beholder saw just just as display frame shown in Figure 20 106, zero lap each other in lines window 203.

In display frame shown in Figure 21 107, " B " and " C " in the text line 201 swell for stereo display seems.In this case, for the beholder, " B " that is seen and " C " not only overlap each other in lines window 203, and " B ", " C " also be adjacent separately around literal overlapping.

In example shown in Figure 21, if the example that kind shown in the image pattern 19 only is the display position of adjustment anaglyph, then be not enough, this can't eliminate to each other overlapping of literal.To this,, under prerequisite, the display position of anaglyph and the grand output of stereopsis are adjusted in the lump within lines window 203 scopes according to aforesaid processing action.Thus, the literal in the text line 201 that the beholder saw just just as display frame shown in Figure 22 108, zero lap each other in lines window 203.

(enlarging adjustment function in the viewing area)

Figure 23 is that anaglyph generating apparatus 1 is for realizing enlarging the flow chart of the action that the adjustment function is carried out in the viewing area.

Shown in figure 23, at first, control part 2 carries out the processing identical with the abovementioned steps S201 shown in Figure 17 to be obtained literal shape object display message and obtains the literal display region information, and also obtains non-legible shape object display message (step S301).Secondly, three-dimensional amount is set handling part 22 and is carried out the processing identical with abovementioned steps S202, sets the grand output (step S302) of given literal.

Then, display position is set handling part 21 and is carried out the processing identical with abovementioned steps S203, to 2 literal of adjacency, and mean place (step S303) between the mean place between calculating anaglyph L1 and R1 and anaglyph L2 and R2.Then, display position is set handling part 21 and is carried out the processing identical with abovementioned steps S204 to judge whether two mean places have overlapping, and literal viewing area handling part 23 judges whether the stereopsis of literal is in (step S304) in the literal viewing area.

In step S304, overlapping if judged result is that average bit is equipped with, or stereopsis not in its literal viewing area (" denying "), then literal viewing area handling part 23 judges whether the literal viewing area can enlarge (step S305).At this, if judged result is that the literal viewing area can enlarge, then handling part 23 pairs of literal viewing areas in literal viewing area enlarge (step S306).Under the state that has been able to enlarge in the literal viewing area; Display position is set handling part 21 and/or three-dimensional amount and is set handling part 22 and carry out the processing identical with abovementioned steps S205, comes the display position and/or the grand output of anaglyph are adjusted (step S307).

Then, display position is set handling part 21 and literal viewing area handling part 23 carries out the processing identical with step S206, judges through above-mentioned adjusted two mean places zero lap whether, and judges whether stereopsis is positioned at its literal viewing area (S308).At this, if judged result is that two mean place zero laps and stereopsis are in (" being ") in its literal viewing area, then the literal display region information in 23 pairs of information retaining section 24 of literal viewing area handling part is upgraded (step S309).

Thereafter, processing advances to step S207.In addition, in step S304,, then advance to step S108 if judged result is that mean place zero lap and stereopsis are in its literal viewing area.In addition,, can not enlarge, then handle advancing to step S307 if judge the literal viewing area at step S305.When advancing to step S307, might solve the overlapping of mean place fully and run off the stereopsis part outside the literal viewing area, but can relax to a certain extent.

At this, explain according to the display effect after the grand output of the display position of having adjusted anaglyph in the literal viewing area of such scheme after expansion and/or stereopsis.What Figure 24 represented is, 2 literal of stereo display and literal display frame 109 in an overlapping time the in the lines window around it.What Figure 25 represented is, 2 literal of stereo display and the display frame 110 during zero lap in the lines window of literal after expansion around it

In display frame shown in Figure 24 109, " B " in the text line 201 and " C " are seemed by stereo display in lines window 203 and swell.In this case, for the beholder, " B " that is seen and " C " not only overlap each other in lines window 203, and " B ", " C " also be adjacent separately around literal overlapping.

In example shown in Figure 24, if be the grand output of adjusting the display position and the stereopsis of anaglyph according to aforesaid scheme only, then be not enough, this might cause literal to run off the scope of lines window 203.To this, according to aforesaid processing action, earlier lines window 203 is enlarged, then the display position of anaglyph and the grand output of stereopsis are adjusted in the lump.Thus, the literal in the text line 201 that the beholder saw just just as display frame shown in Figure 25 110, zero lap each other in lines window 203.
