For reducing quantity of information, take parallax additive process at present embodiment, however,, introduced the notion of " boundary " in order to obtain to have more the image of depth sense through simplifying.This boundary is to be positioned at nearby to be used to control 32 layers the imaginary plane of describing (W0-W31) to the depths from screen as shown in figure 10.In the present embodiment, can set 32 layers of boundary at most, each layer boundary can be put some among a BG or the OBJ of maximum 1024 characters compositions.In addition, when putting BG, boundary can be regarded as the level or the unit of background painting.Flame Image Process IC223 (with reference to Fig. 2) is from innermost boundary W31, in regular turn the attribute information that sets with reference to each boundary (boundary attribute): to video memory 224 carry out each boundary describe handle.That is to say, maximum 32 layers of boundary are in addition overlapping, form piece image.
In the present embodiment, can determine the display priority between BG/BG, OBJ/BG, the OBJ/OBJ by the setting of boundary.Specifically, BG on forward relatively (little sequence number) boundary or OBJ are than the BG or the OBJ that lean on relatively on inboard (big sequence number) boundary, display priority height.For example, being in BG on the N boundary or OBJ is depicted on the BG that is on the inboard adjacent N+1 boundary or the OBJ.Thereby when BG or OBJ had lap between adjacent boundary, as long as BG or OBJ on the boundary of the place ahead do not have transparent part, BG on the one side boundary of the inside or OBJ, its lap were just covered by BG on the boundary of the place ahead or OBJ, can't see on screen.In addition, be between the OBJ/OBJ on the identical boundary according to the write sequence of the OBJ attribute on the DAM2253 and set display priority, but the display priority between boundary, its degree of priority is higher.
Present embodiment is considered qualitative difference between BG and the OBJ, and manages to show BG and OBJ with diverse ways.Next the display packing of BG and OBJ is described.
The display packing of BG at first is described.BG is that the BG reflection that launches from BGMM2251 (referring to Fig. 8) cuts a picture that to need the zone, sticks on cutting the picture that the optional position shows on the display screen.Can cut out the picture of minimum 1 (horizontal stroke) * 8 (indulging) picture point by a picture point unit from the BG reflection to maximum 384 (horizontal stroke) * 224 (indulging) picture point scopes.In addition, no matter the beginning coordinate X that cuts out, Building Y mark can be that unit specifies with a picture point.
The BG reflection is a base unit with the BG picture of 512 * 512 picture point sizes as shown in figure 11.Claim the base unit of this BG to be the figure section in the present embodiment.Figure section by 64 * 64 promptly the character block of 4096 8 * 8 picture points gather together and form.In addition, Figure 11 is the medelling synoptic diagram of BG reflection, on the BGMM2251 of reality, as shown in figure 12, is this identification serial number of storing each character in proper order by the position number on the BG reflection among Figure 11 (0-4095).This identification serial number is exactly a sequence number of distributing to each character on the character RAM2246 (referring to Fig. 9) of video memory 224.That is to say that what character RAM2246 stored is 2048 character datas that transmit selectively from the zone 413 of storer 41 (referring to Fig. 5), each character data is distributed to certain character ordinal number of selecting in the middle of the 0-2047.Thereby, on the BG reflection, adopt these 2048 kinds of characters to show the BG picture.
In addition, BGMM2251 has the zones of the BG reflection that can store 14 figure sections in the present embodiment.Thereby the present embodiment electronic game computer can be videoed with 14 width of cloth BG at most in order to make a width of cloth picture.But also a plurality of figure sections can be made up, be handled as a BG reflection.The maximum number of the figure section that can make up is 8.
Shown in the present embodiment be to specify the character recognition sequence number to make the method for displaying image of the so-called character mode of BG reflection, to gather the bit map mode of making the BG reflection with picture point good but the present invention adopts.
Next the display packing that OBJ uses is described.OBJ is that the character block by independent assortment 8 * 8 picture points forms as shown in figure 13.In other words, reasonably manage, make selected character block in display frame, connect by demonstration coordinate to the character block that chooses.Available number of characters up is 1024 in a width of cloth display frame.Select in the middle of 2048 characters that these 1024 characters can write down from the character RAM2246 (referring to Fig. 9) of video memory 224 to use.
As the OBJ of display object, have character less one by one, a plurality of discontinuous configurations in display frame.Therefore, manage, on picture, suitably dispose character block, can use storer efficiently for the coordinate position that shows necessary each character block.Make and allow OBJ from BG reflection, cut rectangular frame, to stick on display frame again and show that just must dispose many character blocks that do not show on reflection, memory span is wasted as BG.But in the present embodiment, OBJ serves as basic size with 8 * 8 picture points, thereby manages to show than its little object.And, when showing, be that unit increases size also with 8 picture points than its big object.But the present invention does not limit the size of OBJ, and the OBJ size is not that 8 * 8 picture points are good.
On the other hand, BG has bigger viewing area on screen, and state variation is also few, and has the character that can dispose continuously.Therefore, it is more suitable to cut the method that rectangular block sticks on the display screen optional position from pre-prepd BG reflection.If make BG identical with OBJ, with regard to each character display coordinate is managed, attribute information will increase too much, gives to describe to handle and brings excessive load.
Figure 14 is the medelling synoptic diagram of the OBJ attribute configuration of OAM2253 (referring to Fig. 8) storage.As previously mentioned, OBJ can be set on 4 layers at most in 32 layers of boundary.Therefore, corresponding with the number of plies that sets as shown in figure 14 in OAM2253, be divided into four groups at most, write down the OBJ attribute.Flame Image Process IC223 (referring to Fig. 2) retrieves the boundary attribute, finds to be set with the boundary of OBJ, just OAM2253 is retrieved, the OBJ that describes here to be write down.The retrieval of OAM2253 is to begin to carry out in order from the OBJ that write down the bigger position of OAM sequence number (0-1023), describes corresponding OBJ's.The display priority of the OBJ that describes later in boundary is higher.Four groups of boundaries are specified by OBJ control register SPT0, SPT1, SPT2, SPT3 (not shown).Be set with among the OBJ control register SPTx (x=0-3) and be in the OAM sequence number (from 0 to 1023) of each group when minimum (address the is bigger) position of medium priority.In addition, if in OBJ control register SPT3, be set with OAM sequence number 1023, then no longer include vacant zone in the middle of the OAM.
Figure 15 represents to be written to the formation of the OBJ attribute relative with character block of OAM2253.The OBJ attribute is formed (each word comprises 16 of 2 bytes) by 4 words.Among Figure 15, JX is 16 bit strip symbol (plus or minus) integers, is illustrated on the display screen the axial display position of OBJX (7-383).JY also is that (integer is illustrated on the display screen the axial display position of OBJY (7-223) to 16 bit strip symbols.JP is 14 bit strip symbol integers, expression show in the coordinate system of OBJ parallax amount (256-255).JLON is 1 bit flag, and whether expression shows OBJ on left screen.JRON is 1 bit flag, and whether expression shows OBJ on the screen of right side.JCA is 11 integers, the character ordinal number of expression 1 to 2047.Other attribute informations and the present invention among Figure 15 do not have direct relation, its explanation of Therefore, omited.
The OBJ that Figure 16 shows on each frame buffer 2241-2244 (referring to Fig. 9) or the display screen shows coordinate system.This OBJ shows that the scope that coordinate system had is to (383,223) from (0,0).Initial point (0,0) is selected in the left end topmost of display screen.Different therewith, the scope that the space of OBJ attribute JX, JY performance has is that (7 ,-7) are to (383,223).This be because, occur from the screen left end hero for example, walk to the right side this time, need be shown as character content at first at the screen left end and engender.When the hero occurs walking to downside from screen upper end too.The Flame Image Process IC223 of Fig. 2 reads the corresponding character data of JCA (character ordinal number) in the middle of the OBJ attribute with Figure 15 from the character RAM of Fig. 9, describes the character data that this is read on the assigned position on left image and/or the right image frame buffers (position of JX, JY, JP regulation).At this moment, Flame Image Process IC223 deducts or adds parallax amount JP value for JX, determines to be shown in the Building X mark (promptly being painted into the Building X mark of left-right frames impact damper) of left and right sides screen with this.But, then need not add and subtract parallax amount JP for JY.Embody with formula, be
JXL=JX-JP (the Building X mark on the screen of a JXL=left side)
JXR=JX+JP (the Building X mark on the right screen of JXR=)
JYL=JYR=JY (the Building Y mark on JYR, the JYL=left and right sides screen)
Figure 17 represents to write the boundary attribute of one deck boundary among Fig. 8 WAM2252 and forms.Below with reference to Figure 17 boundary attribute composition is described.As shown in figure 17, each boundary attribute is set on the attribute list of 16 words.Can set 32 layers of boundary (referring to Figure 10) on the WAM 2252 from W0 to W31.By the setting of boundary attribute, can to describe BG or describe OBJ, be to describe BG on one side or OBJ sets in screen both sides, the left and right sides or certain.In any situation that can set on each boundary under following four kinds of situations.
1:1 BG (BG boundary)
2:1 above 1024 following OBJ (OBJ boundary)
3: do not have whatever to distribute (illusory boundary: do not show whatever)
4: as mentioned above, the Flame Image Process IC223 of Fig. 2 is according to W31 → W30 → W29 for control boundary (final boundary) ... the order of W0 is from the image that the is positioned at the screen depths good boundary of drawing-setting in regular turn.The boundary that display priority is the highest is W0, next then be W1, W2 ... W31.According to software, when not needing to use whole boundary, can set the boundary of control usefulness, only required boundary is described with high-level efficiency.When for example adopting 3 layers of boundary, can carry out following setting.
W31, W30, W29 → as the boundary of describing usefulness
The final boundary of W28 → then be set at
W31: distant view
W30: middle scape (the middle scenery of distant view and close shot)
W29: close shot is set like this, and according to the priority of boundary, scape image in distant view image the place ahead shows shows the close shot image in middle scape image the place ahead, thus can according to the distance sense corresponding priority level rendering image that superposes.Flame Image Process IC223 skips the processing of W28-W0, thereby processing speed has accelerated.Much less, processing speed is out of question, 3 layers of boundary can be set on any boundary.At this moment, no boundary can be set at illusory boundary.
Among Figure 17, the boundary attribute comprises attribute information GX, the GY, the GP that where make stipulations that the BG image that takes out is presented at display screen in the middle of the BG reflection.GX is 16 bit strip symbol (plus or minus) integers, is illustrated in the central X axis position (0-383) of coordinate system that shows BG.GY is 16 signed integers, is illustrated in Y-axis in the middle of the coordinate system that shows BG to position (0-223).GP is 16 bit strip symbol integers, be illustrated in the middle of the coordinate system that shows BG parallax amount (256-255).Flame Image Process IC223 calculates by following formula, calculates the coordinate position of actual displayed on display screen.

Right eye is marked (dst XR)=GX+GP with the Building X
In addition, the boundary attribute also comprises attribute information MX, MY, the MP that its initial position of view data that takes out from the BG reflection is stipulated.MX is the integer of 16 bit strip symbols (plus or minus), is illustrated in the X axis position (0-4095) in the coordinate system of BG source.MY is 16 bit strip symbol integers, is illustrated in Y-axis in the coordinate system of BG source to position (0-4095).MP is 16 bit strip symbol integers, be illustrated in the coordinate system of BG source parallax amount (256-255).Flame Image Process IC223 calculates by following formula, calculates the coordinate position of reality from the data of BG reflection taking-up.
Left eye is marked (src YL)=MY-MP with the Building Y
Right eye is marked (src YR)=MY+MP with the Building Y
In addition, the boundary attribute also comprises attribute information W, the H that the BG size (window size) on the display screen is stipulated.W is illustrated on the display screen BG in the figure place of X-direction.H is illustrated in the figure place of BG Y direction on the display screen.For left eye (src XL, MY) to (src XL+W, MY+H) scope is cut out BG, from display screen (dst XL, GY) position begins to show.For right eye, then (src XR, MY) to (src XR+W, MY+H) scope is cut out BG, from display screen (dst XR, GY) position begins to show.
In addition, the boundary attribute also comprises the BG picture that takes out from BG reflection is depicted on some left image frame buffers (2241 or 2242) and the right image frame buffers (2243 or 2244) or is depicted on both, promptly to some demonstration the in left eye and the right eye, still both are shown the attribute information LON, the RON that make stipulations.This LON, RON are respectively 1 bit flags, represent following state corresponding to setting value.
LON=0: on left image frame buffers, do not describe
LON=1: on left image frame buffers, describe
RON=0: on right image frame buffers, do not describe
RON=1: describe in addition on right image frame buffers, LON, RON were all 0 o'clock, and then expression is not described on this boundary.
In addition, the boundary attribute also comprises the attribute information BGM that the display mode of BG picture is stipulated.This BGM forms by two, corresponding to four kinds of patterns below the value representation that sets.
The common BG display mode of BGM=00
BGM=01 line displacement BG display mode
The affine BG display mode of BGM=10
The common BG display mode of BGM=11 OBJ display mode is exactly the pattern that shows common BG image.Line displacement BG display mode is to make each line displacement 1 row of its X-direction show the pattern of BG image.Affine BG display mode is the pattern that BG image augmentation/dwindle/rotate is shown.The OBJ display mode is the pattern that shows OBJ.At this moment, Flame Image Process IC223 is with reference to the OBJ attribute of setting among the OAM2253.
In addition, the boundary attribute comprises attribute information SCX, the SCY that stipulates as the screen size of the BG of object reflection.SCX forms by 2, corresponding to the value that sets the X axis size of BG reflection is made following regulation.SCY also forms by 2, corresponding to the value that sets, the Y-axis of BG reflection is made following regulation to size.
SCX: screen size X
SCX=00 512 picture points (1 figure section)
=01 1024 picture point (2 figure section)
=10 2048 picture points (4 figure section)
=11 4096 picture points (8 figure section) SCY: screen size Y
SCY=00 512 picture points (1 figure section)
=01 1024 picture point (2 figure section)
=10 2048 picture points (4 figure section)
=11 4096 picture points (8 figure section) can be stipulated a BG image size that makes up by the combination of above-mentioned SCX, SCY in 1-8 figure segment limit.
Whether the boundary attribute also comprises its boundary is the attribute information END that final boundary (エ Application De ワ-Le De) is stipulated.This END is 1 bit flag, corresponding to the following two states of value regulation that sets.
The boundary that END=0 this time handles is not final boundary
The boundary that END=1 this time handles is final boundary
The boundary attribute also comprises 4 attribute information BGMAP_BASE.Be set with the base address of BG reflection among this BGMAP_BASE, promptly as the video sequence number (0 to 13) of first figure section of the BG of object.
The boundary attribute information also comprises attribute information PARAM_BASE.This attribute information PARAM_BASE is set with the base address of parameter list, and this parameter table stores has the parameter that adopts in line displacement BG display mode, the affine BG display mode.
In addition, other attribute informations do not have direct relation with the present invention among Figure 17, thereby omit its explanation.
Be recorded in the picture on the BG reflection,, can be from the optional position cut and describe by size (1 * 8-384 * 224) arbitrarily by the setting of boundary attribute.When attribute information BGM sets common BG display mode, the parallax amount GP on display screen, when the BG reflection cuts frame out also with reference to parallax amount MP.What parallax amount MP considered is, when the BG that will cut out regards window as, different from the picture scope that left eye, right eye are seen.As shown in figure 18, be from (MX, (MX ± MP MY) cuts frame out from the BG reflection MY) in the position of X-direction skew parallax amount MP with respect to cutting initial point.And, on display screen, be with respect to showing that (GX GY) at X-direction skew parallax amount GP, shows the picture that cuts to initial point again from the BG reflection.
Therefore, store the required a plurality of BG reflections of whole BG of forming appearance in the recreation in the zone 412 of storer 41.And along with the carrying out of recreation, when displaying contents has bigger variations (when for example changing level or carry over scape), 412 select the required BG of BG that should show this platforms or the scene to video (up 14 figure sections) from the zone, are sent to BGMM2251.
Required a plurality of boundary attributes when the zone 414 of storer 41 stores the displaying contents platform that great changes have taken place or scene initial picture separately described.So change level or during the carry over scape, just the 414 required boundary attributes when selecting to describe the initial picture of this platform or scene from the zone are delivered to BGMM2251.The boundary attribute of setting among the BGMM2251 according to games, rewrote use by CPU221 next time before changing level or carry over scape.
Present embodiment adopts the way of the interpolation parallax of two kinds of novelties that in the past do not have in order to show stereo-picture with less quantity of information.Basically be to generate the picture that two width of cloth have parallax according to a breadth to reach the purpose that reduces quantity of information.Method to the new interpolation parallax that adopts in the present embodiment is illustrated below.
The interpolation parallax method that OBJ uses at first is described.Roughly say, OBJ be allow same picture on the screen of the left and right sides on X-axis (level) direction skew on the contrary show with the corresponding distance of parallax amount JP, add parallax.
Supposition now adopts 4 characters with the zag image point patterns shown in Figure 19 (a)-(d) to show OBJ.Each character (a)-(d) is assigned character ordinal number (JCA) 20,8,10,1023 respectively.And supposition, each character (a)-(d) is set by the sort of OBJ attribute shown in the zag image point patterns right side respectively.Under Figure 19 situation, the parallax amount JP of each character is 0, thus each character on display screen so that (JX, JY) original position of defined begins to show.Thereby demonstration OBJ shown in Figure 20 on the display screen.
And when shown in Figure 21 (a)-(d), when each character setting has parallax, the display position of each its X-direction of character shows (referring to Figure 22 (a)) at left screen superior displacement to (JX-JP), shows (referring to Figure 22 (b)) at right screen superior displacement to (JX+JP).The X axis display position is staggered and the corresponding distance of parallax amount JP in the opposite direction, will see that object flies closely, or see that object a long way off.Observe the image shown in Figure 22 (a) and (b) with images of left and right eyes respectively, will be as shown in figure 23, from beginning to see successively the segment of character ordinal number 20 at the moment, the segment of character ordinal number 8, the segment of the segment of character ordinal number 10 and character ordinal number 1023.
Relation between parallax amount and the far and near sense more specifically, when parallax amount was 0, the player feel as shown in figure 24, OBJ as if be positioned at the benchmark screen and go up equally.And work as parallax amount is timing, and the player then feels as shown in figure 25, OBJ as if nearer more the same at the moment than the benchmark screen.And when the vision residual quantity when negative, the player then feels as shown in figure 26, OBJ as if shielding than benchmark more the depths is the same.Thereby, during the performance close shot, get parallax amount (left and right sides image deviations amount) for just, make that parallax amount is an increment.And performance is then got parallax amount for negative during distant view, makes that parallax amount is a decrement.
Next the method for the interpolation parallax of BG is described.In the present embodiment, adopt 2 kinds of methods of adding parallax for BG.
First kind of interpolation parallax method of BG is the interpolation parallax way identical with OBJ.Specifically, allow exactly and cut the width of cloth picture that in oppositely skew and the corresponding distance of parallax amount GP (referring to Figure 17) on X-axis (level) direction on the screen of the left and right sides, add parallax by BG reflection.
Second kind of interpolation parallax method of BG is according to adding parallax with above-mentioned first kind of opposite thinking of adding the parallax method.Specifically, be in the middle of the BG reflection, on X-direction, oppositely to be offset and the corresponding distance of parallax amount MP, cut left and right sides picture, two width of cloth pictures that cut out are presented on the same position of left and right sides screen, add (referring to Figure 27) of parallax.At this moment, the parallax amount GP on the screen is set at 0 good.This second kind method that adds parallax is for example to be used for showing this time than the distant view thing of seeing through that window sees.As shown in figure 27, from the distant view that window is looked, the scope that the scope that left eye is seen and right eye are seen different really.Second kind to add the parallax method very effective when the distant place scenery that can see from window is bigger than window frame size, but when the scenery that shows than window frame size hour, it is good to adopt first kind of moving the coordinate that shows side to add the parallax method.In addition, the cubic periphery of display screen can be used as window and consider, thereby when the BG picture that BG reflection cuts full screen size (384 * 224 picture point) showed, this second kind adds the parallax way also was effective.
In addition, first kind adds parallax way and second kind and adds parallax way both and adopt that to add parallax good.This way that adds parallax can be used for for example the observable distant view of penetrating window being shown, also wants before eyes or the inside when showing window itself.
Figure 28 is the process flow diagram of describing to move of expression present embodiment.And Figure 29-Figure 31 is a process flow diagram of representing each subroutine procedure among Figure 28 in detail.Below, with reference to Figure 28-Figure 31, the action of describing of present embodiment image/sound treating apparatus 22 execution is described.
At first, CPU221 transmits or rewrites and describes needed data (step S101).That is, when CPU221 closes at power supply, displaying contents have bigger variation change level or during the carry over scape, storer 41 in the search program card 4, required BG reflection, boundary attribute, line displacement parameter, affine parameter etc. are delivered to image working storage 225, required character data etc. is delivered to video memory 224.Displaying contents with just person's picture do not have much not simultaneously, CPU221 then according to the games of storer 41 storages, rewrites boundary attribute, OBJ attribute, line displacement parameter and the affine parameter etc. of 225 storages of image working storage.
Then, Flame Image Process IC223 is set at 31 with counter n, and counter x is set at 1 (step S102).Counter n is the counter of counting as the sequence number of the boundary of process object, and does paired negative value and also can count.Counter x is the counter of counting as the order of the OBJ boundary of process object.Next, Flame Image Process IC223 judges that whether the count value of counter n is to 0.The count value of counter n surpasses at 0 o'clock, and Flame Image Process IC23 just reads the boundary attribute (step S105) of the boundary Wn corresponding with the count value of counter n from image working storage 225.
Next, Flame Image Process IC223 judges whether the object boundary Wn that this time handles is final boundary (step S106).Attribute information END (referring to Figure 17) contained in this basis for estimation boundary attribute carries out.When boundary Wn was not final boundary, Flame Image Process IC223 judged whether this boundary Wn is the illusory boundary (boundary that does not show again; LON=0, RON=0) (step S107).When boundary Wn was illusory boundary, Flame Image Process IC223 subtracted 1 (step S108) with regard to the count value that makes counter n, is back to the action of step S104.And as boundary Wn neither during the also non-illusory boundary of final boundary, Flame Image Process IC223 just judges the OBJ boundary, still is common BG boundary, still is line displacement BG boundary (step S109-S111).This judgement is to carry out according to attribute information BGM contained in the boundary attribute.
At first, processing when boundary Wn belongs to common BG boundary is described.At this moment, the various attribute informations that Flame Image Process IC223 sets according to the boundary attribute, that carries out common BG describes operation (step S112).Figure 29 represents the particular content that this step S112 subroutine is handled.Figure 18 then medelling represents that this describes the principle of operation.Referring to Figure 29 and 18, Flame Image Process IC223 is according to the attribute information GX, the GY that set in the boundary attribute, GP (Building X cursor position, Building Y cursor position, parallax amount that the demonstration coordinate of BG is fastened), calculates to describe initial position (step S201) on the left-right frames impact damper (referring to Fig. 9).Next, attribute information MX, the MY that Flame Image Process IC223 sets according to the boundary attribute, MP (Building X cursor position, Building Y cursor position, parallax amount that the source(-)holder mark of BG is fastened) calculate from the central initial position (step S202) that cuts BG of BG reflection.Next, attribute information W, the H that Flame Image Process IC223 sets according to the boundary attribute (X-direction picture point size, Y direction picture point size that BG source(-)holder mark is fastened) calculates from the central size (step S203) of cutting BG of BG reflection.Next, the attribute information BGMAPBASE that Flame Image Process IC223 sets according to the boundary attribute selects the BG reflection (step S204) that needs in the middle of a plurality of BG reflections from BGMM2251 (referring to Fig. 8).Next, Flame Image Process IC223 is on selected BG reflection, and scope (above-mentioned steps S202, S203 calculate the scope of obtaining) cuts BG data (is character ordinal number in present stage) (step S205) according to the rules.Next, Flame Image Process IC223 reads and the corresponding character data of character ordinal number of cutting then from character RAM2246 (with reference to Fig. 9), is depicted in regulation zone on the frame buffer 2241,2243 (or 2242,2244) (position that calculates with above-mentioned steps S201 is as the zone of describing the starting position) (step S206).
Next, illustrate that boundary Wn is the processing under the situation of OBJ boundary.At this moment, Flame Image Process IC223 in the middle of the OAM2253 (referring to Fig. 8) with reference to corresponding group OBJ attribute (step S113 of the count value of counter x; Referring to Figure 14).Then, the character ordinal number JCA (referring to Figure 15) that Flame Image Process IC223 sets according to the OBJ attribute of institute's reference, read corresponding character data from character RAM2246, this character data of reading is depicted in regulation zone on the frame buffer 2241,2243 (or 2242,2244) (with the position of JX, JY, JP regulation as the zone of describing initial position) (step S114).Next, Flame Image Process IC223 makes the count value of counter x add 1 calculating (step S115).
Next, processing when boundary Wn is line displacement BG boundary is described.At this moment, the line displacement parameter of the various attribute informations that Flame Image Process IC223 sets according to the boundary attribute and zone 2255 storages of image working storage 225, that carries out line displacement BG describes operation (step S116).Figure 30 represents the particular content that this step S116 subroutine is handled.Referring to Figure 30, attribute information GX, GY, GP that Flame Image Process IC223 sets according to the boundary attribute calculate and to describe initial position (step S301) on the left-right frames impact damper (referring to Fig. 9).Next, attribute information MX, MY, MP that Flame Image Process IC223 sets according to the boundary attribute calculate from the central initial position (step S302) that cuts BG of BG reflection.Next, the attribute information PARAM_BASE that Flame Image Process IC223 sets according to the boundary attribute reads required line displacement parameter (step S303) from the zone 2255 of image working storage 225.Then, Flame Image Process IC223 calculates from the central size (step S304) of cutting BG of BG reflection according to the attribute information W, the H that set in the boundary attribute.
Next, the line displacement amount parameter that Flame Image Process IC223 reads according to above-mentioned steps S303 is calculated (step S305) again to the X-direction read-out position from the BG reflection.Here, the Building X that the source data that makes actual BG video is read time institute's reference is designated as BGXL, BGXR, and the line displacement parameter of left screen is HOFSTL, and the line displacement parameter of right screen is HOFSTR, and then step S305 carries out following calculation process.
BGXL＝MX-MP+HOFSTL
BGXR=MX+MP+HOFSTR in addition, line displacement Parameter H OFSTL and HOFSTR represent the side-play amount of X-direction, it be 16 bit strip symbol integers (512-511).In the present embodiment, each horizontal line has skew, so the line displacement parameter needs the so many parameters of BG horizontal direction line number.When for example opening the BG of full screen size, need set the parameter list of 224 * 2=448 word size in the zone of image working storage 225.
Then, the attribute information BGMAP_BASE that Flame Image Process IC223 sets according to the boundary attribute selects required BG reflection (step S306) in the middle of a plurality of BG reflections from BGMM2251 (referring to Fig. 8).Next, Flame Image Process IC223 scope (above-mentioned steps S302, S304, S305 calculate the scope of obtaining) according to the rules on selected BG reflection cuts BG data (present stage is a character ordinal number) (step 307).At this moment, the BG data can be read from the position that is offset HOF-STL, HOFSTR value with respect to the original read-out position of X-direction (MX scholar MP) again.Then, Flame Image Process IC223 reads and the corresponding character data of character ordinal number that cuts from character RAM2246 (referring to Fig. 9), is painted into regulation zone on the frame buffer 2241,2243 (or 2242,2244) (position that calculates with above-mentioned steps S301 is as the zone of describing initial position) (step S308).
Next illustrate that boundary Wn neither belongs to the OBJ boundary, do not belong to common BG boundary again, neither line displacement BG boundary, but the processing during affine BG boundary.At this moment, Flame Image Process IC223 is the affine parameter of storage in the zone 2255 of the various attribute informations that set according to the boundary attribute and image working storage 225, carries out (step S117) that affine BG describes work.Figure 31 represents the particular content that this step S117 subroutine is handled.With reference to Figure 31, attribute information GX, GY, GP that Flame Image Process IC223 sets according to the boundary attribute calculate and to describe initial position (step 401) on the left-right frames impact damper.Then, the attribute information PARAM_BASE that Flame Image Process IC223 sets according to the boundary attribute reads required affine parameter (step S402) from the zone 2255 of image working storage 225.Follow attribute information W, H that Flame Image Process IC223 sets according to the boundary attribute, calculate the demonstration size (step S403) of the central BG of BG reflection.Then, Flame Image Process IC223 is according to the affine parameter read, and picture point is calculated and section gone out position (step S404) on the BG reflection one by one.So this affine BG describes not use in the pattern attribute information MX, MY and the MP in the middle of the boundary attribute.
Then, the attribute information BGMAP_BASE that Flame Image Process IC223 sets according to the boundary attribute selects required BG reflection (step S405) in the middle of a plurality of BG reflections from BGMM22251.Then, Flame Image Process IC223 is on selected BG reflection, and scope (above-mentioned steps S404 calculates the scope of obtaining) cuts BG data (present stage is a character ordinal number) (step S406) according to the rules.Then, Flame Image Process IC reads and section corresponding character data of character ordinal number that goes out from character RAM2246, be painted into regulation zone on the frame buffer 2241,2243 (or 2242,2244) (position that calculates with above-mentioned steps S401 is as describing initial position, and the zone of being determined by step S403) (step S407).
Character data is alternately to be painted on the 2 framing impact dampers (2241,2,243 one groups, 2242,2,244 one groups).During describing character data to a certain group, the display image data that is stored in another group then is read out, and gives LED unit 212L and 212R shows by SAM2247.
As mentioned above, present embodiment is two scanning systems (system that binocular is watched), to make the one dimension led array luminous to 214L, 214R (each file is arranged with 224 picture points respectively) with the synchronous suitable timing of the swing of catoptron 217L, 217R, the player watches it through catoptron 217L, 217R.Like this, the player is because the visual persistence effect of eyes, see as if about show that to be formed with a width of cloth screen in the system the same.Making recreation have a stereoscopic sensation, must about show that system emits the different pictures (picture of left and right sides different pieces of information) of band parallax.But show to be different picture datas about will transmitting simultaneously by a Flame Image Process IC223, comparatively difficult from processing power.In addition, about show that the peak value consumed power was bigger when system showed different images simultaneously, maximum consumption power is increased.Therefore, present embodiment is considered burden, the dispersion peak value consumed power that alleviates Flame Image Process IC, shows about making that the demonstration time of system staggers mutually to avoid overlapping.
About representing respectively, Figure 32 and Figure 33 show the mirror tilt phase place of system and the relation between the Displaying timer.The hunting frequency that makes each catoptron 217L and 217R is 50Hz (1 cycle was 20ms), and transverse axis is the time, and the longitudinal axis is a pendulum angle, and then the action of catoptron 217L and 217R is respectively as Figure 32 and shown in Figure 33.Be the sine wave swing.Left and right sides catoptron is synchronously swing mutually, and phase place separately staggers 180 ° mutually, overlaps to avoid the left and right sides screen display time.If with 1 cycle 20ms eight equal parts, the action of catoptron is corresponding like that with the sequence number 1-9 among Figure 32 and Figure 33 with sine wave.When repeating 1 to 9 action swing, the angular velocity of catoptron is also non-constant.But move to 6 or 8 when moving to (2) from 4, angular velocity is more stable.In order to reduce the distortion of screen the right and left, the left side that is presented at of led array shows that system carries out during this 4 to 6, and the right side shows that system then carries out during this to (2) 8.In addition, the demonstration time is equivalent to
Cycle, about 5ms.The picture point number of led array is 224.Led array 214L and 214R light 384 times with suitable timing in the above-mentioned demonstration time, thus about show that system forms the screen of horizontal 384 * vertical 224=86016 picture point.This screen is called the imaging screen.
Be illustrated in the left side as an example Figure 34 and show to be the position of projection imaging screen.Among Figure 34, sequence number 4,5,6 is corresponding with the position number of Figure 32.Led array 214 is lighted in the metastable place of catoptron 217L angular velocity as previously mentioned, thereby catoptron 217L moves at 6 o'clock from 4, just the scanning imagery screen.When catoptron 217L was in position 4, the light of led array 214L was at 4 ' position scioptics 216L, 4, and " position is depicted the picture screen as.When moving to 5,6 positions, catoptron 217L too, depicts the picture screen as on ", 6 " toward 5.The direction of scanning of screen is from left to right.Different people's eyesight differences, thereby need mobile lens 216L, make the screen focusing.This is called the eyesight adjustment.The position of the lens of eyesight adjustment usefulness is prepared several.For example lens 216L is moved to-the 1D position, can before about 1 meter, see the imaging screen.Figure 34 represents that the left side shows system, but the right side shows system too, and the screen scanning direction also is from left to right.
Figure 38 and Figure 39 represent the relation between photosensitive interrupter output state and the anti-dazzling screen moving direction.In addition, the direction when Figure 38 represents the 73 output declines of shading interrupter detects, and the direction when Figure 39 represents the 73 output risings of shading interrupter detects.Shown in Figure 38 (a), direction interrupter 74 is output as low level the time, and 73 outputs of shading interrupter are from left to right just can judge the moving direction of anti-dazzling screen in case descend.Shown in Figure 38 (b), when direction interrupter 74 was output as high level, 73 outputs of shading interrupter were in case decline is to turn left from the right side just can judge the moving direction of anti-dazzling screen.Shown in Figure 39 (a), when direction interrupter 74 was output as high level, in case 73 outputs of shading interrupter are risen, making the moving direction that can judge anti-dazzling screen was from left to right.Shown in Figure 39 (b), direction interrupter 74 is output as low level the time, and 73 outputs of shading interrupter are to turn left from the right side just can judge the moving direction of anti-dazzling screen in case rise.
As mentioned above, present embodiment is to carry out screen display at catoptron angular velocity in stable time.But strictly speaking, internal reflector angular velocity (sweep velocity) still is not constant during this.Therefore need to revise.
Vertical row of imaging screen are called file, always have 384 files.File on the imaging screen wide (file at interval) depends on that LED lights the time.Figure 40 represents is state when imaging screen middle body and marginal portion display text " D ".If make led array to light the time interval identical with the marginal portion at imaging screen middle body, will see the marginal portion horizontal compression, or see the middle body cross directional stretch on the contrary.This be because, compare with 4,6 o'clock the catoptron angular velocity (sweep velocity) in position, the angular velocity when position 5 (sweep velocity) is always very fast, but the time of lighting of LED was undertaken by the identical time interval.That is to say that in Figure 40, imaging screen middle body led array is lighted time interval PPC and equated with the time interval PPE of marginal portion.
To show with identical file width with the marginal portion at imaging screen middle body,, just must change the LED fluorescent lifetime at interval corresponding to sweep velocity to avoid distortions such as figure, literal.Specifically, as shown in figure 41, need be revised, imaging screen middle body will shorten LED fluorescent lifetime PPC at interval more, and the marginal portion is then wanted time expand interval PPE more.Each file width is equated.In addition, LED led pulse width (PWC, PWE) has uniform brightness in order to make imaging screen marginal portion and middle body, will make it constant when same brightness.
Stored in order to revise the form that LED lights the timing data in the time interval and be called the file table.This file table is stored in the zone 416 (referring to Fig. 5) of storer 41, can be sent in the zone 2254 of the image working storage 225 in the agent set according to program when power supply closes.Flame Image Process IC223 lights the time with reference to the file table control LED that launches in the image working storage 225.The initial address of file table is transmitted as 8 bit serial data by the catoptron control circuit 211 of control catoptron action.
The file table is not only the time data of 384 files, supposes that also there be the state and the state that is subjected to external interference of deviation in catoptron, has the so many extra timing datas in 68 files * 2.In the present embodiment, LED lights the time interval can per 4 files set one.Thereby, be a record with 4 files, then the record number of file table just has 17+96+17=130 (=520 file).
File table configuration on Figure 42 presentation video working storage 225.As shown in figure 42, the file table is that data ordering as 512 words is distributed on the image working storage 225.Flame Image Process IC223 receives the file table with reference to initial address CTA from catoptron control circuit 211.This file table with reference to initial address CTA be as respectively with left eye with, right eye with corresponding 8 bit data, when left screen display begins (during the L_SYNC rising) send automatically by catoptron control circuit 211.The file table that sends is to be set by the register 223a (referring to Figure 43) in the Flame Image Process IC223 with reference to initial address CTA.In addition, among Figure 43, CTA_L be a left side with the file table with reference to initial address, CTA_R be right with the file table with reference to initial address CTA.The file table that Flame Image Process IC223 sets according to internal register 223a is read timing data COLUMN_LENGTH with reference to initial address CTA in the middle of the corresponding record of file table, be set in (referring to Figure 44) among the internal register 223b.Timing data COLUMN_LENGTH is by the 200ns resolution numerical value of 1 file time of definition.Per 4 files are read timing data one time from the file table.During the display frame, concerning left eye with and right eye use, carry out 96 times (=384/4 time) respectively, carry out altogether 192 times.
Among Figure 42, for example when left picture shows beginning, in case read timing data from left eye with the A address (being the address that left file table is represented with reference to initial address CTA_L) of file table, after this just with byte address, the order from (A-2) number address, (A-4) number address ... read timing data.As mentioned above, this reading is to carry out once per 4 file times, and interior left and right 96 (=384/4) of carrying out respectively are inferior during the display frame.The address of finally reading of left side picture is (A-95 * 2)=(A-190) number address.Equally, can read the timing data of number address of B address-(B-190) from right file table.
The in addition instruction that comes of also with good grounds games of present embodiment is listed as by the timing data in the file table being rewritten as special data, carries out the fluctuate function of the special demonstration of this class of for example display frame.
The display action of present embodiment below is described.Agent set 2 is during by controller 6 energized, and CPU221 starts games, and the file table that the storer 41 of program card 4 is stored is sent to the zone 2254 of image working storage 225.Existing make begins, and it is synchronous that then left and right sides catoptron 217L, 217R just are in the synchronizing clock signals FCLK that the internal oscillator (not shown) with catoptron control circuit 211 produces, the state that vibrates with the cycle of 20ms.At this moment, anti-dazzling screen 71L, 71R just by (referring to Figure 35) in photosensitive interrupter 72L, the 72R, provide 2 marking signal by photosensitive interrupter 72L, 72R respectively to direct motor drive/sensing circuit 215L, 215R.In the middle of 2 the marking signal wherein 1 be the output signal of shading interrupter 73, in addition 1 then is the output signal (referring to Figure 37) of direction interrupter 74.Direct motor drive/ sensing circuit 215L, 215R carries out wave shaping with the marking signal of feeding, and then exports catoptron control circuit 211 to.
Here, the production method of file table with reference to initial address CTA is described.Figure 45 represents the relation between the mirror tilt phase place and shading interrupter 73 output signals (to call shading interrupter signal in the following text) under the catoptron bias free state.Figure 46 represents that there is the relation between the mirror tilt phase place and shading interrupter signal under the deviation state in catoptron.The deviation of catoptron is that error, the external interference (when for example game device uses at a slant) because of when assembling produces.During the catoptron bias free, the high level partial pulse width α of shading interrupter signal equates as shown in figure 45 at every turn.In contrast, when catoptron has deviation, the high level partial pulse width of shading interrupter signal as shown in figure 46, the front and back pulse width in 1 cycle (20ms) is different value (2 to 4 pulse width is β from the position, and 6 to 8 pulse width is γ from the position).Here, the ratio (β/γ) corresponding of pulse width before and after the part of the high level in 1 cycle with mirror aberration amount Δ.The file table need change according to this departure Δ with reference to initial address.This be because, catoptron bias free and when deviation is arranged, it is different to be used for the mirror tilt phase place (angular range) that image shows.Therefore, catoptron control circuit 211 calculates the ratio of high level part front and back pulse width in the last display cycle, manages to obtain the file table with reference to initial address CTA according to this operation result.Be transformed to the file table with reference to initial address CTA from the ratio of pulse width, can utilize map table, also available Calculation Method.
Action when Figure 47 presentation video processing IC 223 receives from the serial data of catoptron control circuit 211.Referring to Figure 47, Flame Image Process IC223 receives each serial data of 8 from catoptron control circuit 211, be file table during, this file table stored into the regulation zone (step S502) of register 223a (referring to Figure 43) with reference to initial address CTA_L and CTA_R respectively with reference to initial address CTA_L and CTA_R (step S501).Next, Flame Image Process IC223 increases the bits of offset of regulation figure place on reference to initial address CTA_L or CTA_R at the file table of register 223a storage, the file table is transformed to the address (step S503) of the figure place that is fit to the appointment of file table address with reference to initial address CTA_L or CTA_R with this.
The left side that Flame Image Process IC223 obtains according to above-mentioned steps S503 or right file table begin to read timing data from the file table with reference to initial address.The action of Figure 48 presentation video processing IC 223 when the file table is read timing data.Referring to Figure 48, Flame Image Process IC223 at first sets initial value (step S601) at counter M and N.Counter M is the counter of 384 row files on the screen being counted every 4 row, and the initial value of She Dinging is 95 here.This initial value 95 is a basis with 384/4=96.Counter N then be to the count value 1 of counter M the counter counted of 4 suitable row files, the initial value of She Dinging is 3 here.Next, Flame Image Process IC223 sets a left side that above-mentioned steps S503 obtains or right file table with reference to initial address (step S602) at internal register L or R (not shown).Specifically, Flame Image Process IC223 (when left side demonstration commencing signal LSYNC rises) when showing left picture sets left file table with reference to initial address in register 1, (when right demonstration commencing signal R_SYNC rises) sets right file table with reference to initial address in register R when showing right picture.
Next, Flame Image Process IC223 with reference to initial address, reads timing data D (step S603) from the appropriate address of file table (storing the zone 2254 of image working storage 225) according to the file table of setting among register L or the R.Then, Flame Image Process IC223 sets the timing data D (step S604) that reads in counter C.Then, Flame Image Process IC223 makes this counter C subtract 1 (step S605).Successively decreasing of counter C undertaken by the cycle, carried out every 200ns in the present embodiment.By successively decreasing, in a single day the count value of counter C becomes 0, and promptly during counter C output carry signal, Flame Image Process IC223 is output latch clock signal (step S607) just.This latch clock signal is delivered to led driver 212L or 212R.
Here, led driver 212L and 212R comprise shift register 2131 as shown in figure 49, latch cicuit 2132 and intednsity circuit 2133.Shift register 2131 can be stored 1 file (224 picture point; 224 * 2=448 position) view data that sends from SAM2247 (referring to Fig. 9) of share.The above-mentioned latch clock signal of 2132 response image processing IC 223 of latch cicuit, the data that shift register 2131 is stored latch.Each LED that 2133 view data that latch according to latch cicuit 2132 of intednsity circuit are controlled led array 214L or 214R lights, extinguishes and brightness.
By providing Flame Image Process IC223 the latch clock signal of output to led driver 212L or 212R, latched by the view data of latch cicuit 2132, lighted led array 214L or 214R by intednsity circuit 2133 with 1 file of shift register 2131 storages.Thereby can on a left side or right screen, carry out the demonstration (step S608) of vertical 1 row.At this moment, Flame Image Process IC223 can transmit the next column view data to shift register 2131 from SAM2247.
Then, Flame Image Process IC223 judges whether the count value of counter N is 0 (step S609).The count value of counter N is not 0 o'clock, and owing to the demonstration of 4 illustrations as data finishes as yet, Flame Image Process IC223 makes counter N subtract 1 (step S610).After this, the action of Flame Image Process IC223 repeating step S604-S610.The demonstration of 4 row view data finishes, and the count value of counter N becomes at 0 o'clock, and Flame Image Process IC223 judges just whether the count value of counter M is 0 (step S611).The count value of counter M is not 0 o'clock, because the demonstration of the view data of a picture does not finish as yet, Flame Image Process IC223 makes counter M subtract 1 (step S612).Then Flame Image Process IC223 can deduct 2 (step S613) with reference to initial address by byte address with the left side or the right side file table of register L or R storage.Thus, file table next column timing data just becomes and reads object.After this action of Flame Image Process IC223 repeating step S603-S613.The demonstration one of one width of cloth picture finishes, and the count value of counter M promptly becomes 0, and Flame Image Process IC223 constipation bundle is from file table data readout time.
Next, the action of whole demonstration system is described with reference to the time diagram of process flow diagram, Figure 51 and Figure 52 of Figure 50.At first Flame Image Process IC223 sets initial value (the step S701 of Figure 50) in counter G.The setting value of counter G is corresponding to contained display frame frame number in the 1 recreation frame.During initial setting, the value of determining corresponding to initial picture (for example 0) is set among the counter G.Next, the synchronizing clock signals FCLK rising (step S702) of catoptron control circuit 211 outputs.Flame Image Process IC223 is corresponding to judge whether the count value of counter G is 0 (step S703).Here, in case the count value of counter G is 0, Flame Image Process IC223 just makes recreation clock signal GCLK rising (step S704).Next Flame Image Process IC223 switches (step S705) to the display object frame buffer.For example, precedingly once select frame buffer 2241,2243, and the view data that will store is sent to image-display units 21 when showing herein, Flame Image Process IC223 then selects frame buffer 2242,2244 as this time display object.On the contrary, once preceding, frame buffer 2242,2244 is selected during as display object, and Flame Image Process IC223 just selects frame buffer 2241,2243 as current display object.Initial then the frame buffer (for example frame buffer 2241,2243) of selecting default value to determine.Next, Flame Image Process IC223 sets certain value (step S706) in counter G.Generally counter G sets 0.And in ensuing recreation frame, carried out describe working load when heavier, can in counter G, set value more than 1 according to the load of machinery systems.Depend on sub-games to describing the whether judgement of overload of power, so be the instruction that comes according to CPU221.
Next, the left side of catoptron control circuit 211 outputs shows commencing signal L_SYNC rising (step S707).Flame Image Process IC223 correspondingly carries out the display process (step S708) of left eye with image.That is Flame Image Process IC223 reads the left file table of catoptron control circuit 211 transmissions with reference to initial address CTA_L (referring to Figure 47), from the appropriate address of file table, calls over timing data (referring to Figure 48).At this moment at interval, from the pulse of Flame Image Process IC223 output latch by each timing data official hour of reading.Therefore, each shown file width of LED unit 212L can be revised according to the timing data of file table record, revises to such an extent that make each file width even.But in the present embodiment,,, carry out once every 4 row in order to alleviate the processing burden of Flame Image Process IC223 to the correction of file width.Next, the right side of catoptron control circuit 211 outputs shows that commencing signal R_SYNC rises (step S709), and Flame Image Process IC223 just carries out the display process (step S710) of right eye with image.This right eye also is to carry out using with the left eye of step S708 the roughly the same processing of display process of image with the display process of image.
By above-mentioned explanation and Figure 51 as can be known, left eye staggers on the time in a display frame with the display process of image with the display process of image and right eye and carries out.Therefore, can alleviate the burden of Flame Image Process IC223.And the peak value consumed power is disperseed, and can alleviate maximum consumption power.Therefore, can set the throughput of current/voltage lower.So design can reduce cost easily.
After this, Flame Image Process IC223 is back to the action of step S702.Arrive as next display frame, when synchronizing clock signals FCLK rises (step S702), Flame Image Process IC223 judges just whether the count value of counter G is 0 (step S703).The count value of counter G is 0 o'clock, and Flame Image Process IC223 carries out the following action of step S704 once more.And the count value of supposition counter G is not 0 o'clock, and Flame Image Process IC223 just makes count value G subtract 1 (step S711).After this following action of Flame Image Process IC223 repeating step S707.At this moment owing to do not switch frame buffer as display object, thereby about show to be shown to be and last identical picture.That is shown in Figure 52, when contained display frame was a plurality of in 1 recreation frame (being stipulated by recreation clock signal GCLK), each display frame just showed same frame in the present embodiment.To loading heavy (data volume is big) when image is described, Flame Image Process IC223 describes to handle the cause that does not finish in a display frame because of as previously mentioned for this.Then, the action of Flame Image Process IC223 circulation repeating step S702-S711.
, in the present embodiment, instruction file table in the update image working storage 225 in the middle of recreation that CPU221 can be next according to games.By this, can on image-display units 21, show this class stunt picture that for example fluctuates.In addition, can be to be stored in advance in the program storage in order to the data of upgrading the file table, also can be CPU221 according to the calculating formula that provides on the games by calculating the data of upgrading in the file table.Like this, in the present embodiment, common picture data can use same as before, simultaneously is processed into the stunt picture according to the instruction on the Games Software, but thereby can increase the variation of display frame under the prerequisite that does not increase data volume.
In addition, the foregoing description describes as electronic game computer, but stereoscopic display device of the present invention is not limited thereto, and also can be widely used in trainer, instruments used for education, this class of guiding device and have device shown.
In addition, the foregoing description is disposed at display near two of the players, but will stagger demonstration or project on television receiver or the screen good with the left and right sides image of parallax in time.At this moment, the player can put on a kind of have with television receiver on left and right sides image switching time synchronized, the glasses that alternately make left and right sides eyeglass carry out the tripper (for example liquid crystal shutter) of on-off action watch display image.Make left and right sides image modification color show good in addition.That is, can be with the left image of certain a branch of demonstration in the RGB three-beam electron-beam, with the right image of a branch of demonstration in the middle of the two remaining bundles.At this moment, the player must have on the glasses that left and right sides eyeglass is equipped with different color filters and observe display image.In addition, change the polarized light angle and show left and right sides image, the player puts on polarised light glasses and watches good.Below the explanation left and right sides image that will have a parallax shows or is projected in embodiment on television receiver or the screen.
