Subsequently, switch controlling device 10 cut- off switch 11 and 12, and off/on switches 13 and 14 is so that input picture A1 is input to frame memory 2 by these switches 13 and 14 former states.Thereby input picture A1 writes frame memory 2 by switch 13 and 14.Then, input picture A1 is input to display unit 3 from frame memory 2.And display unit is shown as the 2-D image to input picture A1.At this moment, input picture A1 can be transfused to image A 2 and replaces; Using input picture A1 still is that A2 can arbitrarily set.
Next, the work of the display unit under the situation that is set to left eye 2-D image display mode in display mode information M1 is explained.Switch controlling device 10 cut- off switch 11 and 12, and off/on switches 13 and 14 is so that left eye image data L is imported into 2-D image processing system 6, and 2-D image processing system 6 is connected to frame memory 2 respectively.Thereby left eye image data L is imported into 2-D image processing system 6 by switch 13.2-D image processing system 6 uses this left eye image data to form the 2-D image, and the image of this formation is written to frame memory 2 by switch 14 then.Then, the 2-D view data is input to display unit 3 from frame memory 2.Thereby display unit 3 shows the 2-D view data of this input.
Fig. 2 shows at display mode information M1 and indicates under the situation of the pattern that left-eye image L is shown as the 2-D image, by 2-D image processing system 6 data structure that forms and the method that is used to show these data.Vertically be decomposed into histogram at hypothesis left eye image data L and arrive under the situation of L8 as L1, part left eye diagram data L (in the frame that the runic of the left eye image data L shown in Fig. 2 is represented) is used to as the 2-D view data that is formed by 2-D image processing system 6.Here, suppose that L2-L7 is shown.In Fig. 2, show two frame viewpoints, just preceding viewpoint and last viewpoint.In last frame viewpoint, in order to simplify, the slit (describing in detail in the back) that does not draw and be used for the 3-D display mode.Understand that in Fig. 2 the L2 of 2-D view data 201 is to be watched by user's left eye to L7.Thereby the user can be the image-watching from the L shaped one-tenth of left eye image data the 2-D image.
From the above mentioned, though display unit 3 can both allow 3-D to show and 2-D shows, this device 3 can only allow 3-D to show.Fig. 3 has shown in display mode information M1 indication and left eye image data L has been shown as under the situation of pattern of 2-D image, and how 2-D image processing system 6 forms the example how data and data are shown.And, suppose here display unit show with reference to the identical image of the illustrated image of Fig. 2.Display unit 3 has thereon the screen with slit 300.Be presented at the ribbon image L2 in the frame 301, L4 and L6 are sent to user's left eye respectively, and ribbon image L3, and L5 and L7 are sent to user's right eye respectively, so as the user can from the image of the L shaped one-tenth of left eye image data as the 2-D image-watching.Slit on the screen of display unit 3 can be replaced by lens.
In display mode information M1, be set to similar under the situation of right eye 2-D image display mode and in the left eye 2-D image display mode, form the 2-D image and be presented on the screen from eye image.
Next, the work of display unit when display mode information M1 is set to the 3-D image display mode is described.Specified at display mode information M1 under the situation of 3-D image display mode, switch controlling device 10 is connected the also state of control switch 14 of switch 11 and 12, so that 3-D image processing system 1 is connected to frame memory 2.Like this, left eye image data L and eye image data R are input to 3-D image processing system 1 from the outside by switch 11 and switch 12 respectively.Thereby 3-D image processing system 1 forms the 3-D view data and the data that form is written in the frame memory 2.Then, the 3-D view data is input to display unit 3 from frame memory 2.At last, display unit is shown as the 3-D image to the 3-D view data of input.
Fig. 4 has shown how to form the example how 3-D view data and this view data are shown.Here suppose respectively by vertically decomposing left eye image data L acquisition ribbon image L1, by obtaining ribbon image R1 to R8 at vertical eye image data R that decomposes to L8.The size of supposing the image level direction that is shown is less than the size of the horizontal direction of the size of the horizontal direction of left eye image data L and eye image data R.For example, in eye image shown in Fig. 4 and left eye image data, runic represents that as shown in Figure 4, the 3-D view data is used ribbon image L2 under the situation of image of frame of actual displayed, R3, and L4, R5, L6 and R7 form.And, because slit 300 or lens are arranged on the screen of 3-D image-display units, be presented at the ribbon image L2 of 3-D view data 301, L4 and L6 are sent to user's left eye, and be presented at ribbon image R3 in the 3-D image-display units, R5, R7 are sent to user's right eye, so the user can watch the 3-D image.
In the example shown in Fig. 4, illustrated how to form (merging) 3-D view data by narrowing (thinning out) and merging input image data.Though the 3-D image processing system 1 shown in Fig. 1 can be accomplished to narrow and merge, and narrows and also can finish by external equipment, and only finish merging by 3-D image processing system 1.In the later case, be input to the left eye image data L of 3-D image processing system 1 and eye image data R from the outside and only become respectively by L2, L4, L6, L8 constitute and only by R1, R3, and R5 and R7 constitute.
In this embodiment, made a kind of adjustment, reduced the 3-D image parallactic under the situation last till Preset Time so that show at the 3-D image.Next, how to handle the 3-D image parallactic and how to see each 3-D image with reference to Figure 18 explanation.
In Figure 18, user's left eye and the distance between the right eye are assumed to be " e ", and the distance between user and the display screen is assumed to be " L ".And in Figure 18 A, eye image all is located in point (P1) identical on the screen with left-eye image.At this moment, User Recognition to this image seemingly this image just on display screen.
Then, as shown in Figure 18 B, the image of watching by right eye by from P1 to the distance " w " that moves to left.Eye image has arrived position P2.At this moment, viewed to image be to be positioned at S1 seemingly, so User Recognition to this image seemingly it towards user's distance ' ' d ' ' of from screen, having come out.
Then, shown in Figure 18 C, eye image is by the distance " w " that moves right from P1.Thereby eye image has arrived position P3.At this moment, image is viewed to it is positioned at S2 seemingly.Thereby the user recognizes this image and has stepped back a distance ' ' d ' ' from display screen seemingly.
In general, the parallax of 3-D image is different between each pixel.The user's who receives from entire image 3-D image impression is known as " parallax (parallax) " here.To illustrate that in the back parallax adjusts by the relative position that changes left-eye image and eye image in the horizontal direction.
Next, how the 3-D image-display units shown in the key diagram 1 shows the 3-D image.
In initial condition, the 3-D image-display units shows the 3-D image with default parallax A (S1 ').Time measurement/judgment means 4 is measured the demonstration time of 3-D image at parallax A subsequently.In such cases, Measuring Time when device 4 shows beginning from the 3-D image.When the 3-D image was shown, 3-D image processing system 1 sent to time measurement/judgment means 4 to 3-D image display notification signal.After receiving 3-D image display notification signal, time measurement/judgment means 4 beginning measurement time t 1.
Time measurement/judgment means 4 judges subsequently whether the time t1 that measures surpasses preset time T IME1 (S12).In judged result is that step 11 is gone in control under ' denying ' situation of (not surpassing), and here, time measurement/judgment means 4 continues to be presented at the 3-D image of parallax A.For under the situation of ' being ' (surpassing), time measurement/judgment means 4 outputs to parallax control device 5 to time measurement end signal T1 in judged result.
When receiving time measurement end signal T1, parallax control device 5 order 3-D image processing systems 1 form the 3-D image by reducing parallax.3-D image processing system 1 reduces parallax subsequently and forms the 3-D image.Simultaneously, device 1 sends to time measurement/judgment means 4 to reset signal.Thereby 3-D image processing system 1 is stored original parallax (parallax A).Therefore, display unit shows the 3-D image (S13) with parallax B littler than parallax A.
For example, when the 3-D view data was formed, stored here " parallax information " represented with reference to the relative position of left eye image data L by the eye image data R that locatees on the 3-D view data.And, in the frame that the runic shown in the relative Fig. 4 with left-eye image of 3-D image processing system 1 each eye image of storage is represented in upper left coordinate (x, position y).
The upper left point of image is defined as under the situation of initial point (0,0) in Fig. 4, and horizontal direction is defined as " x ", and vertical direction is defined as " y ", and the position on the right side of the frame represented of runic and a left side all is respectively (1,0) then.
At this moment, when minimizing seemed parallax at the 3-D of display screen front image, this 3-D image was moved more near display screen by reorganization backward.Specifically, eye image data R is moved right in the horizontal direction with respect to left eye image data L.When increasing parallax, the 3-D image is moved to the front of display screen by reorganization.Specifically, eye image data R is moved to the left in the horizontal direction with respect to left eye image data L.
When minimizing seemed parallax at the 3-D of display screen back image, this 3-D image was moved forward more near display screen by reorganization.When increasing parallax, the 3-D image is moved to the screen back by reorganization.
The direction that moves when at this moment, the direction that moves of eye image data R seems before display screen with the 3-D image is opposite.
Next, how describe with reference to table 2 pair by moving in the horizontal direction the example that parallax that left eye image data L adjusts object 3-D image forms the 3-D image.
Table 2
| Require left eye image data L | Require eye image data R | |
| Before current display position during mobile 3-D image | With the sequence arrangement view data of L and R, use outer (left side) limit part then | With the sequence arrangement view data of L and R, use outer (right side) limit part then |
| Behind current display position during mobile 3-D image | With the sequence arrangement view data of L and R, (right side) limit part in using then | With the sequence arrangement view data of L and R, (left side) limit part in using then |
When the eye image data R by the left eye image data L of each part and part forms one during to the 3-D image that moves in current display position the place ahead,, use the exterior domain target recombinant 3-D image of each L and R then the sequence arrangement of view data with L and R.When mobile 3-D image behind screen, the sequence arrangement of view data, then with the inner region of each L and R this 3-D image of recombinating with L and R.For example, when coordinate (1,0) is set to the upper left corner of the frame that the runic shown in Fig. 4 represents and the upper right corner, form the 3-D image that moves before the screen, will be made as upper left corner coordinate (0,0) and upper right corner coordinate and be made as (2,0) this 3-D image of recombinating.When behind screen, moving this 3-D image, will be made as upper left corner coordinate (2,0) and upper right corner coordinate and be made as (0,0) this 3-D image of recombinating.
Next, describe how to form the 3-D view data with reference to Fig. 6 by the minimizing parallax.Fig. 6 has shown and how to form the 3-D view data and how make this 3-D image seem example before screen its demonstration by reducing parallax.For example, the 3-D view data shown in Fig. 4 is used to show the 3-D image that seems before screen.At this moment, when showing the 3-D image by the minimizing parallax, this 3-D image is recombinated, and it is just in time moved behind screen.In other words, as illustrated at table 2, the frame that runic is represented among Fig. 6, its upper left corner coordinate is set as (0,0) in left eye image data L, be set as (2,0) in eye image data R.
The L1 of left eye image data L, L3 and L5 are set at the L2 of the 3-D view data shown in Fig. 4, the position of L4 and L6.Equally, the R4 of eye image data R, R6 and R8 are set at the R3 of the 3-D image shown in Fig. 4, the position of R5 and R7.The L1 of 3-D image, L3 and L6 are watched by left eye, and R4, R6 and R8 are watched by right eye, thus the user can be identified as the 3-D image to this 3-D view data.
When reducing the parallax of 3-D image, the frame that the runic shown in Fig. 4 is represented is moved to the left in left eye image data L, and in eye image data R, the frame that runic is represented moves right, to form target 3-D image.When increasing the parallax of 3-D image, the frame that runic is represented is moved round about forms target 3-D view data.
Be modified because its demonstration time surpasses preset time T IME1 at 3-D image with parallax A, so that under the situation with littler parallax B demonstration, the current Measuring Time of time measurement/judgment means 4 replacements also begin to measure the time t2 that the 3-D image shows with new parallax B.
Then, time measurement/judgment means 4 is the time t2 that measure and preset time T IME2 compare (S14).Also do not arrive under the situation of TIME2 at time t2, control turns back to step 13, and time measurement/judgment means 4 continues to show to have the 3-D image of more neglecting poor B.In measurement time t 2, the demonstration time that just has the 3-D image of parallax B arrives under the situation of preset time T IME2, and time measurement/judgment means 4 outputs to parallax control device 5 to time measurement end signal T2.After parallax control device 5 receives signal T2, output to 3-D image processing system 1 being stored in the signal that is used to recover parallax in the 3-D image processing system 1.After 3-D image processing system 1 receives this signal, recover parallax originally and form target 3-D image and reset signal is sent to time measurement/judgment means 4.At this moment, time measurement/judgment means 4 can be recovered original parallax A immediately, or the 3-D image that formation is shown is progressively to increase parallax.
As mentioned above, under the parallax of 3-D image was changed situation into another, 3-D image processing system 1 outputed to time measurement/judgment means 4 to reset signal.Time measurement/judgment means 4 resets to 0 to Measuring Time after receiving this reset signal, and then the beginning Measuring Time.As mentioned above, the 3-D that time measurement/judgment means 4 is measured at default parallax shows the time, and adjusts parallax according to the result of time measurement and form target 3-D image.
Next, pair at 3-D image processing system 1, the signal of exchange describes in time measurement/judgment means 4 and the parallax control device 5 with reference to table 3.
Table 3
State [1-1] expression was measured by 4 time starteds of time measurement/judgment means.At this moment, 3-D image processing system 1 outputs to time measurement/judgment means 4 to 3-D image display notification signal.This signal indication display unit is showing the 3-D image.
The Measuring Time of state [1-2] express time measurement/judgment means 4 arrives preset time T IME1.At this state, time measurement/judgment means 4 passes through to reduce the signal that parallax forms the 3-D image being used to represent that the time measurement end signal T1 of the TIME1 time of advent is sent to parallax control device 5 thereby 5 outputs of parallax control device are used for order 3-D image processing system 1.After receiving this signal, 3-D image processing system 1 outputs to time measurement/judgment means 4 to the reset signal that is used for replacement time/judgment means 4.
The Measuring Time of state [1-3] express time measurement/judgment means 4 arrives scheduled time TIME2.At this state, time measurement/judgment means 4 is being used to represent that the time measurement end signal T2 of the TIME2 time of advent outputs to parallax control device 5.And therefore, 5 outputs of parallax control device are used for order 3-D image processing system 1 by recovering the signal that original parallax forms the 3-D image.Simultaneously, 3-D image processing system 1 is exported to time measurement/judgment means 4 to 3-D image display notification signal.
The parallax that state [1-4] is represented to recover original is to form target 3-D image.At this state, 3-D image processing system 1 is exported to time measurement/judgment means 4 to reset signal.
As mentioned above, even when the user watches the 3-D image for a long time, because 3-D image-display units of the present invention can show each 3-D image by reducing parallax, his/her parallax sensitivity is owing to his/her eye fatigue reduces.Thereby can protect the user to avoid eye fatigue.And when the user had recovered original parallax susceptibility from eye fatigue owing to him when, display unit began to show the 3-D image with original parallax, has only sense of discomfort seldom so that the user can watch the 3-D image once more.Above-mentioned TIME1 and TIME2 can be stored in the memory that provides in the 3-D image-display units with preset value.
Each TIME1 and TIME2 can be not only a value.For example, according to the screen size of input picture, and be to put the time as the full weight of the project relevant under the situation of video data and the quantity of the combination of the parameter that is provided with can be provided with many values for TIME1/TIME2 at input picture with eye fatigue.TIME1/TIME2 also can be provided with or be revised by the user.
The 3-D image-display units also can comprise the separator 504 that is used for the 3-D picture decoding apparatus 400 that 3-D image formatted data F1 is decoded as shown in Figure 7 and is used for the 3-D view data by device 500 decodings are separated into eye image data and left eye image data.In this, 3-D image formatted data F1 can comprise with above-mentioned be stored in advance wherein TIME1 and the value of TIME2 equivalence so that these values can be replaced by TIME1 in the 3-D image-display units and TIME2.Hereinafter, will the work of 3-D picture decoding apparatus 500 be described.3-D picture decoding apparatus 500 comprises 3-D image control data analytical equipment 501, image data decoder 502 and switch 503 and 3-D image formatted data F1 decoded.
Next, 3-D image formatted data F1 will be described.Fig. 8 has shown the example of 3-D image formatted data F1.3-D image formatted data shown in Fig. 8 partly is made of 3-D image control information part and view data.3-D image control information part is made of 3-D image mark information I1 and control information I2.Image mark information I1 indicates whether this 3-D image formatted data F1 is the 3-D image data.The view data part is made of the data D that is encoded.Control information I2 represents above-mentioned TIME1 and TIME2.The data that are encoded in the view data part can be used such as JPEG, and methods such as MPEG are encoded from image, and corresponding left eye image data L and eye image data R flatly are arranged side by side in this image.In 3-D image formatted data F1, data are with I1, the sequential storage of I2 and D.
3-D image control data analytical equipment 501 is analyzed the control information of 3-D image, and judges whether this 3-D image formatted data F1 is the 3-D image data.In judged result is under the situation of ' being ', 3-D image control data analytical equipment 501 outputs to the 3-D image-display units to set 3-D image display mode in the table 1 of the control information I2 of the value of expression TIME1 and TIM2 and expression display mode information M1, and control switch 503 is connected to separator 504 to image data decoder 502 then.Simultaneously, 3-D image control data analytical equipment 501 outputs to image data decoder 502 to decoded data D.Image data decoder 502 will output to the data D decoding that is encoded with generation the 3-D view data W2 of separator 504.Separator 504 is separated into left eye image data L and eye image data R to the 3-D view data W2 of input, then L and R is outputed to the 3-D image-display units as output image data 01 and 02.Dateout 01 and 02 is input to the 3-D image-display units shown in Fig. 1 as input picture A1 and A2.
Value among the control information I2 that provides among the 3-D image formatted data F1 is provided is any one among TIME1 and the TIME2.And preset value can be used for any data that are not stored in control information I2.
For example, when the 3-D image formatted data F1 of TIME1 has wherein only been stored in reconstruct, just control the 3-D image and show minimizing parallax when making 3-D image demonstration time arrival TIME1.Yet after this, take arbitrarily to control demonstration by each reconfiguration device.In other words, when the 3-D image demonstration time arrives TIME1, allow to carry out following processing.
(i) continue to show that the 3-D image that reduces parallax is up to next power-off.
(ii) relevant reconfiguration device setting is equivalent to the time of TIME2, and recovers original parallax as mentioned above.
(iii) relevant reconfiguration device is provided with Preset Time, and conversion 3-D image is shown as the demonstration of 2-D image when the 3-D image demonstration time arrives Preset Time.
Although in the above in the example when measuring numerical value that 3-D shows the time and arrive TIME1 the parallax of 3-D image be reduced, the 3-D image shows and also can be converted into the demonstration of 2-D image when TIME1 arrives.Therefore, in demonstration, influenced the intention of the content originator of 3-D image, the user can early recover from eye fatigue.
Represent that at 3-D image mark information I1 3-D image formatted data F1 is not under the situation of 3-D image data, 3-D image control data analytical equipment 501 is not exported control information I2.Replace, 3-D image control data analytical equipment 501 outputs to the 3-D image-display units to the information of the direct display mode of indication input picture as display mode information M1.Simultaneously, 3-D image control data analytical equipment 501 change over switches 503 are so that image data decoder 502 output image datas 01.Simultaneously, 3-D image control data analytical equipment 501 outputs to image data decoder 502 to the data D that is encoded.Image data decoder 502 is decoded to data D subsequently.Decoded data are assumed to be 2-D view data W1 and as dateout 01 output, it is input to the 3-D image-display units shown in Fig. 1 subsequently as input picture A1.
The view data that is stored among the above-mentioned 3-D image formatted data F1 can be uncoded.For example, these data can be unpressed.
And in the superincumbent explanation, although display mode information M1 obtains from 3-D image control information I1, M1 also can import from the outside, and such input external value can preferentially be used.Yet only when 3-D image control information I1 represented that 3-D image formatted data F1 is not the 3-D image data, the value among the display mode information M1 just forced to specify the direct display mode of input picture.
Further, the 3-D image control information of above-mentioned 3-D image formatted data F1 part can be inserted among the data F1 repeatedly.Fig. 9 has shown the example that how to receive broadcasting 3-D picture material.For example, mobile receiving terminal 22 receives the electric wave of broadcasting 3-D picture material from broadcasting artificial satellite 21.In this, broadcasted content is made of a plurality of program arrangement information sheets and 3-D picture material.3-D image control information part also can be inserted in as the part of information in the program arrangement information.
In 3-D image formatted data F1,3-D image control information part can be inserted in the view data part.For example, with MPEG-4 the situation of the digital coding in the view data part under, 3-D image control information part also can be inserted into the precalculated position of MPEG-4 coded data regulation.
Although time measurement/judgment means 4 time started when the 3-D image shows beginning measures in the explanation in the above, time measurement/judgment means 4 can be worked as receiving broadcast content and begin the back data when receiving for the first time from 3-D image control information part, or begins measurement under 3-D image control information partial data is included in situation in the program arrangement information when the program arrangement information is received for the first time.And under the situation that the program arrangement information on reproduction program time necessary information is included in is received for the first time, time measurement/judgment means 4 can begin Measuring Time when forming the 3-D image by this information.
Although transmit 3-D image formatted data F1 with broadcasting in the above example, also can be used to transmit F1 such as the network of internet.F1 also can be recorded in such as hard disk, replaces top transfer approach on the recording medium of CD etc.
Figure 10 has shown the example that writes down and use 3-D image formatted data F1 stream on recording medium.Hypothesis 3-D view data is imported into 3-D picture coding device 510 now.3-D picture coding device 510 outputs to recording medium 511 to the 3-D image formatted data F1 that forms then subsequently the 3-D coded image data of input and form 3-D image formatted data F1.Recording medium 511 can be hard disk, CD etc., and can write down the numerical data of input.3-D image formatted data F1 outputs to 3-D picture decoding apparatus 512 from recording medium 511.Then, 3-D picture decoding apparatus 512 is similar to above-mentioned 3-D picture decoding apparatus 500,3-D image formatted data F1 decoding, exports control information I2 then, display mode information M1 and 3-D view data.
Figure 11 has shown the example of 3-D image formatted data F1 stream when doing the F1 transmission path with network.For example, the 3-D view data will be imported into 3-D picture coding device 520.3-D picture coding device 520 forms 3-D image formatted data F1 to the 3-D coded image data of input then.3-D image formatted data F1 is sent to 3-D picture decoding apparatus 523 by network 522.3-D picture decoding apparatus 523 is similar to 3-D picture decoding apparatus 500,3-D image formatted data F1 decoding and export control information I2, display mode information M1 and 3-D view data respectively.
The 3-D image formatted data F1 that is sent out can be converted into be convenient to BS, the data that CS and other broadcast systems use.For example, the 3-D view data can be imported into 3-D picture coding device 520.3-D picture coding device 520 forms 3-D image formatted data F1 to the 3-D coded image data of input, then the formatted data F1 that forms is outputed to the BS data and forms device 521.The BS data form device 521 and use 3-D image formatted data F1 to form the BS data then, then the BS data that form are outputed to BS data deciphering device 524 by network 522.BS data deciphering device 524 forms 3-D image formatted data F1 to the BS data decode of input, then F1 is outputed to 3-D picture decoding apparatus 523.Then, 3-D picture decoding apparatus 523 is similar to 3-D picture decoding apparatus 500,3-D image formatted data F1 decoding, exports control information I2 then respectively, display mode information M1 and 3-D view data.
By such method, the 3-D image-display units can obtain TIME1 and TIME2 in the numerical value being arranged on control information I2, for use in object handles.Display unit is convenient to be set to the 3-D image according to object data TIME1 that will show and TIME2.
Next, the situation that three input pictures are arranged of handling is described.Figure 12 has shown the module map of the 3-D image-display units among first embodiment when display unit is handled these three input pictures.
This 3-D image-display units comprises that the input (input picture X, Y, and Z) that is used to use the multi-view image data of taking from three viewpoints forms the 3-D image processing system 600 of 3-D view data, outputs to frame memory 2 to the 3-D view data then; Any one that is used for from multi-view image forms the 2-D image processing system 6 of 2-D image; Be used for the switch 11,12,601 to 603 that switches in the I/O view data; Be used for using the multi-view image data to produce 3-D and show still to be the switch controlling device 604 that the display mode information M ' 1 that shows of 2-D controls these switches according to indication; Be used to store the frame memory 2 of the input picture of the image that forms by 3-D image processing system 600 or 2-D image processing system 6 or former state; 3-D demonstration and 2-D demonstration are all allowed, and be shown as the display unit 3 of 3-D image or 2-D image according to 1 view data that is stored in the frame memory 2 of display mode information M '; Be used for when showing the 3-D image, measuring time measurement/judgment means 4 that the 3-D image shows the time; Order 3-D image processing system 600 to form the parallax control device 5 of 3-D image by the parallax of adjusting each multi-view image with situation about being used at 3-D image demonstration time arrival preset value.
Display mode information M ' 1 will be described hereinafter.
At first, display mode information M ' 1 is input to switch controlling device 604 from the outside.Display mode information M ' 1 has eight types; 3-D image display mode 1 to 4,2-D image display mode 1 to 3 and the direct display mode of input picture.The 3-D image-display units is using the 3-D image display mode of two or three input pictures, uses any one 2-D figure display mode of input picture, and former state shows between direct display mode of input picture of each input 2-D image and switches.

Next, will describe the second embodiment of the present invention.
Figure 14 has shown the module map of 3-D image-display units in the second embodiment of the invention.
In the second embodiment of the invention, the 3-D image-display units comprises the 3-D image processing system 100 that is used for the right eye of input and left-eye image formation 3-D image; Be used for a 2-D image processing system 6 that forms the 2-D image right eye and left eye input picture; Be used for switching respectively the switch 11 to 14 of I/O image to another image; Be used for controlling the switch controlling device 10 of each switch 11 to 14 according to display mode information M1; Be used to store the frame memory 2 of the image that forms by 3-D image processing system 100 or 2-D image processing system 6 or former state input picture; Be used for the image that is stored in frame memory 2 being shown as the display unit 3 of 3-D or 2-D image, be used to measure time measurement/judgment means 101 that each 3-D image shows the time according to display mode information M1; Be used for order 3-D image processing system 100 shows alert message on the 3-D of current demonstration image warning display control unit 102.In this configuration, frame memory 2, display unit 3,2-D image processing system 6, switch controlling device 10, switch 11 to 14 are all identical with those of 3-D image-display units among first embodiment, thereby will use in Figure 14 and numeral/letter identical in first embodiment.
Similar with first embodiment, at first display mode information M1 is input to switch controlling device 10 from the outside.Display mode information M1 identical with in first embodiment.And the work of the display unit in the direct display mode of input picture that uses left eye or eye image and 2-D image display mode is identical with in first embodiment also.
The work of display unit when next, explanation being provided with the 3-D image display mode in display mode information M1.
At first, left eye image data L and eye image data R are input to 3-D image processing system 100 from the outside as input picture A1 and A2 respectively.
In display mode information M1, be provided with under the situation of 3-D image display mode, switch controlling device 10 connect switches 11 and 12 and control switch 14 so that 3-D image processing system 100 is connected to frame memory 2.Then, left eye image data L and eye image data R are input to 3-D image processing system 100 respectively by switch 11 and 12 from the outside.Then, 3-D image processing system 100 forms the 3-D view data, then the view data that forms is write frame memory 2.At last, the 3-D view data is input to display unit 3 from frame memory 2.Thereby display unit 3 is shown as the 3-D image to the 3-D view data of input on screen.
Here, show the work of the 3-D image-display units of 3-D image with reference to being used to shown in the flowchart text Figure 14 shown in Figure 15.
In initial condition, the 3-D image-display units shows 3-D image (S21).So the time measurement/judgment means 100 shown in Figure 14 is measured the demonstration time of 3-D image in procedure for displaying.Then, when the 3-D image is shown, 3-D image processing system 100 sends to time measurement/judgment means 101 to 3-D image display notification signal.After receiving this signal, time measurement/judgment means 101 beginning measurement time t 3.In this, time measurement/judgment means 101 begins Measuring Time when beginning 3-D image shows.
Time measurement/judgment means 101 judges whether the time t3 that measures surpasses preset time T IME3 (S22).In judged result is in ' denying ' absence of (surpassing), and control turns back to step 21, and time measurement/judgment means 101 continues the 3-D image and shows.For under the situation of ' being ' (surpassing), warning display control unit 102 order 3-D image processing systems 100 write out alert message with the 3-D image on the 3-D image that is shown in judged result.After receiving command signal, 3-D image processing system 100 forms message 3-D image so that alert message is coated on the 3-D image that is shown, and exports the image (S23) that is formed then.Thereby warning message is displayed on the foremost (seeming that this message is in sight from the top place of user) of 3-D image.
At this moment, the 3-D image of alert message can form by the message that provides a parallax on the 3-D image that covers current demonstration, merge this two images then, for example, so that the 3-D alert message may be displayed on the finite depth place apart from screen, the user can discern this 3-D message difficultly therefrom.This moment, given parallax was defined as the parallax that the 3-D image shows restriction.
Substitute each the 3-D image in the previous example, only just can form the 2-D image with left eye (right eye) image, parallax is provided for alert message then, so that have only alert message to be shown as the 3-D image.After this, message is capped and merges with the 2-D image becomes the 3-D image.In addition, substitute each the 3-D image in the previous example, also can form the 2-D image with default image, parallax is provided for alert message then.After this, message is capped and becomes the 3-D image with the merging of 2-D image.For example, can form blank screen, then alert message be covered on the screen.
Further, also can use the left eye and the eye image of the 3-D image of current demonstration in each piece that separates by the pixel of predetermined number, to find difference vector.Then, between the vector value that obtains, have therein to the vector value of the message of the degree of depth maximum of screen and be predetermined to be maximum disparity, greater than this peaked parallax message by way of caution.At this moment, given parallax should not surpass 3-D image restriction parallax.Difference vector also can obtain by piece coupling or similar fashion.Maximum parallax also can obtain from the data outside the difference vector of each piece, for example, obtains from the disparity vector of each pixel.
Next time measurement/judgment means 101, and the signal of exchange between the warning display control unit 102, are described at 3-D image processing system 100 with reference to table 5.

The Measuring Time of state [5-2] express time measurement/judgment means 204 has reached preset time T IME4.In this state, time measurement/judgment means 204 is being used to represent that the time measurement end signal T4 that arrives TIME4 outputs to power supply feeding controller 206, and therefore, power supply feeding controller 206 outputs to second time measurement/judgment means 205 being used for Measuring Time is reset to the 0 measurement commencing signal that also starts measurement respectively, and 3-D is shown that inhibit signal sends to mode switch control device 202.
After receiving the measurement commencing signal, second time measurement/judgment means 205 begins Measuring Time T5 (the 3-D image shows the shut-in time) after the 3-D demonstration stops.
Then, step 37 is gone in control.In step 37, display unit judges whether the time t5 by second time measurement/judgment means 205 is measured surpasses preset time T IME5.In judged result is under the situation of ' being ' (surpassing), mode switch control device 202 is provided with 0 in 3-D demonstration prohibitory sign, and in memory, store this sign, then measuring the power supply that stop signal sends to second time measurement/judgment means 205 and " shut " mode" switch controlling device 202.After second time measurement/judgment means 205 receives and measures stop signal, replacement measurement time t 5, thus turn-off the power supply of second time measurement/judgment means 205.
Table 8 has shown the signal of exchange between second time measurement/judgment means 205 and mode switch control device 202.
Table 8
State [6-1] expression reaches preset time T IME5 by the time t5 that second time measurement/judgment means 205 is measured.In this state, second time measurement/205 of judgment means are used to represent that the time measurement end signal T5 that arrives TIME5 outputs to mode switch control device 202, and mode switch control device 202 outputs to second time measurement/judgment means 205 measuring stop signal.
After some unit power supply supplies are turned off, even under the situation that they still are not switched on when having arrived preset time T IME5 (under the situation of the work that does not restart the image demonstration), step 38 is gone in control, mode switch control device 202 is provided with 0 and value of statistical indicant is stored in the memory in 3-D shows prohibitory sign, turn-off all power supplys then and supply power cut-off.
Judged result is that step 39 is gone in control under ' denying ' situation of (not surpassing) in step 37.
In step 39, whether display unit has judged whether that any work is performed with display image, that is to say, have the mains switch of any unit to be pressed.If judged result is ' denying ' (not pressing), step 37 is got back in control, and display unit continues measurement time t 5.For under the situation of ' being ' (pressing), step 40 is gone in control in judged result, and the power supply supply of all display units is switched on.Then, step 41 is gone in control, and display unit forbids that the 3-D image shows following then demonstration 2-D image.
For example, in Figure 16, display mode information M1 and 2-D display mode information M2 are input to switch 201 from the outside.Mode switch control device 202 shows prohibitory sign and finds that value of statistical indicant is 1 with reference to the 3-D that is stored in the memory then.Thereby mode switch control device 202 control switchs 201 are so that 2-D display mode information M2 is input to switch controlling device 200.Switch 201 is connected to the M2 side, so that information M2 is input to switch controlling device by switch 201.
Under left eye 2-D image display mode is arranged on situation among the information M2, switch controlling device 200 stopcocks 11 and 12 and conducting/stopcock 13 so that left eye image data L is imported into 2-D image processing system 6, and control switch 14 is so that 2-D image processing system 6 is connected to frame memory 2.Thereby 2-D image processing system 6 forms left eye 2-D image and by switch 14 image that forms is written in the frame memory 2.The 2-D image is input to display unit 3 from frame memory 2 then.Display unit 2 is shown as the 2-D image with this view data.2-D image this moment is just as being formed when the left eye 2-D image display mode described in the present invention first and second embodiment is set among the information M2.Therefore, each 2-D image is formed and is shown according to 2-D display mode information M2 as mentioned above.
Even when the 2-D image is shown like this, second time measurement/judgment means 205 continues the measurement of time t5, and the time t5 that measures shows that just as top 3-D image situation is imported into mode switch control device 202.In step 42, display unit judges whether the time t5 that measures arrives preset time T IME5.If do not arrive, the demonstration that display unit continues the 2-D image reaches preset time T IME5 up to time t5.When measurement time t 5 reached time T IME5, step 43 was gone in control, and mode switch control device 202 restarts 3-D and shows, delivered to second time measurement/judgment means 205 measuring stop signal.Second time measurement/judgment means 205 receives when measuring stop signal, replacement Measuring Time and stop time measurement.After this, step 33 is got back in control, and mode switch control device 202 shows that prohibitory sign resets to 0 and value of statistical indicant is stored in the memory to 3-D.After this, because 0 be set in the 3-D image prohibitory sign, display unit shows the 3-D image according to display mode information M1 on screen.
At this moment, show that at the 3-D that is used to allow the 3-D image to show the permission signal is imported under the situation of mode switch control device 202, the 3-D image shows that permission message can be displayed on the screen.
Under the situation that the 3-D image is shown by long-time continuous as mentioned above; before arriving preset time T IME5; even when the user attempts the energized supply, still may force power cutoff and forbid that the 3-D image shows, thereby the protection user avoids eye fatigue.Power supply at the 3-D image-display units is turned off, and before arriving preset time T IME5 once more under the situation of energized, display unit can continue the less 2-D image of eyes burden of explicit user then.
When the demonstration time of 3-D image t4 arrives preset time T IME4, have only the power supply supply of display unit 3 to be turned off.After the work of such power cutoff, the power supply supply of display unit 3 can be opened once more by pressing the button.For example, can press the power supply that power knob is opened display unit 3.
Above-mentioned preset time T IME4 represents to appreciate the time continuously, and the user can appreciate target image with the 3-D image therein.Each of time T IME4 and TIME5 can be stored in the memory that the 3-D image-display units provides as preset value.The preset value of TIME4/TIME5 can not be one.For example, with the relevant key element of appreciating the time eye fatigue, such as the input picture screen size, also having at the target input image data is whole reproduction times etc. under the situation of video data, parameter can be used as, and according to the quantity of the combination of these parameters, TIME4/TIME5 can have a plurality of values.The user can be allowed to change the value of TIME4/TIME5.
Just as in the configuration shown in Fig. 7, be used for the 3-D picture decoding apparatus of 3-D image formatted data F3 decoding, separator with being used for the 3-D view data by the decoding of 3-D picture decoding apparatus is separated into right eye and left eye image data can be arranged on before the 3-D image-display units as shown in figure 16.In this, 3-D image formatted data F3 partly is made of 3-D image control information part and view data just as F1 and F2 in first and the two embodiment.Be stored in and be set at the value among the control information I2 and above-mentioned TIME4 and TIME5 value equivalence among the 3-D image formatted data F3.The 3-D image-display units can obtain these from F3 and be worth and use.
Control information I2 among the 3-D image formatted data F3 can have any one among TIME4 and the TIME5, and the preset value among the control information I2 can be used for any data that are not stored in control information I2.
Identical among the work of 3-D picture decoding apparatus and separator and first and second embodiment.Data in the view data part of above-mentioned 3-D image formatted data F4 can be uncoded; For example data can be unpressed.
3-D image control information among above-mentioned 3-D image formatted data F3 part can be similar to that among the present invention first and second embodiment any one is described to be kept on to for example being that the part of program arrangement information is inserted among the F3.
In 3-D image formatted data F3,3-D image control information part can be similar to any one described being inserted in the view data part among the present invention first and second embodiment.For example, under the situation that is set at the view data part with the MPEG-4 coded data, 3-D image control information part can be inserted in by using the specified predeterminated position of MPEG-4 coded data.
As mentioned above, time measurement/judgment means 204 begins to measure when the 3-D image shows beginning.Yet, just as in the present invention first and second embodiment, under the situation of broadcasting, time measurement/judgment means 204 can be after reception broadcasting beginning when first data of 3-D image control information part be received, or under any data of 3-D image control information part are included in situation in the program arrangement information, when the top line arrangement information is received, begin to measure the demonstration time.Under the temporal information that requires to reappear a program was included in situation in first program arrangement information that receives, the time that produces with this information can be used to start any measurement of being carried out by time measurement/judgment means 204.
Although 3-D image formatted data F3 broadcast transmitted in the above description, formatted data also can be transmitted by cable or such as the network of internet.Substitute this transmission, this information can be recorded in such as hard disk, on CD or the similar recording medium.
As mentioned above, the 3-D image-display units is just as can obtain TIME4 and TIME5 from the value in the control information being arranged on 3-D image formatted data F3 in the present invention first and second embodiment.Thereby can as 3-D image data presented TIME4/TIME5 be set easily according to each.And, as mentioned above, under the situation that the 3-D image is shown by long-time continuous, therefore be forced to turn-off the power supply of 3-D image-display units, the power supply of display unit is connected once more by the user then, and the 3-D image-display units can allow to recover to show before forcing power remove.For example, when file is reproduced, under the situation that the power supply of display unit is turned off, display unit can recover to show before power remove.When the user is watching the program of broadcasting channel, under the situation that the power supply of display unit is turned off, the user can be closed to have no progeny and be recovered the broadcasting of same channel immediately in the power supply pressure.
Be equipped with receiving system and the tape deck that is used to receive above-mentioned broadcasting at display unit, or be equipped with receiving system and be connected to external record equipment, watch the 3-D image to surpass under the situation of preset time T IME4 continuously the user, the power supply of display unit is turned off in the time of can working as reception 3-D broadcast of images, and opening entry immediately, and receiving system and tape deck can keep connecting their power supply supply and continue to receive and recorded announce.Therefore, turn-offing the 3-D broadcast of images that writes down when closing when the power supply supply can be reset afterwards.
Though the work of 3-D image-display units illustrates according to the situation of using two input pictures, this embodiment also can use with the present invention first and second embodiment in description in any one same method and be extended to the situation of using three input pictures of handling.
The view data part of 3-D image formatted data F3 can comprise the image of the individual viewpoint of n (n 〉=1).In such a case, 3-D picture decoding apparatus 500 can be according to first is expanded with any one the identical method described in second embodiment with the present invention with separator 504.
3-D image-display units among the invention described above first and second embodiment can be equipped be used to store the device of password and be used to input password and each when the user uses display unit the password importation of requirement password.In this, display unit can be distinguished the user by each password, and is that each user management 3-D image shows the time.
Because each user is distinguished by his/her password, and manage by this way each user 3-D image demonstration time, each user can use the 3-D image-display units and once use display unit under what conditions regardless of other beholders.In other words, because display unit requires his/her password of each user to use display unit and distinguishes each user by this way and manage the 3-D demonstration time, even use display unit at the 3-D image display mode for a long time the user, thereby the power supply supply is forced to close and has no progeny, and another user still can use display unit under the 3-D image display mode.
The 3rd embodiment of the present invention is transformed into the demonstration of 3-D image according to the present invention by the way of adjusting parallax, warning shows and the 2-D image in showing any demonstration and use each user's password also can be applied to the display unit of any compound eye type.
Next, the 4th embodiment of the present invention will be described.
As described in first embodiment, each 3-D image has parallax and user because this parallax and each image is felt as the 3-D image.Although parallax is all inequality between the pixel of each 3-D image, the 3-D image with many big parallax pixels seems that third dimension is more clear and has the less 3-D image of big parallax pixel to seem that third dimension is not really clear.The index of the yardstick of a kind of so relief sensation of expression is known as " 3-D intensity ".The 4th embodiment handles how to limit the 3-D display packing when a plurality of 3-D images have different 3-D intensity levels.
3-D intensity can be determined objectively by the parallax value mean value (the parallax value mean value of the full frame parallax value mean value of still frame and full video image) of pixel, maybe can determine by subjective evaluation.3-D intensity also can be determined by both weighted averages.As subjective evaluation, weighted average, intermediate value, maximum, or the like any one can be used to replace mean value.Under the situation of video, from every frame, obtain maximum, and the peaked mean value of all frames, intermediate value, maximum, or the like any one can be used as the subjective evaluation value.
In general, when watching the 3-D image with big 3-D intensity level, the 3-D image with little 3-D intensity level is more Zao feels eye fatigue to the user than watching, thus the 3-D image allow the demonstration time should be according to 3-D intensity difference.
Figure 19 has shown 3-D intensity (I) and the relation of 3-D image between the demonstration permission time.Figure 19 A has shown the situation of I=1, and wherein supposition can be calculated with the 3-D image and be shown " the integrated intensity " (ordinate) that the time (abscissa) increases with certain speed (k=α).The integrated intensity value was 0 and was TH during at time t1 0 o'clock time.TH represents predetermined threshold value, and 3-D image-display units of the present invention will be finished following processing in the time (t1) when integrated intensity reaches TH.
(1) display mode is shown that from the 3-D image being converted to the 2-D image shows.
(2) reduce parallax and continue the demonstration of 3-D image.
(3) on screen, show alert message.
When employing method (1), t1 represents to continue the permission time (the 3-D image shows the time) that current 3-D image shows.(3) the 3-D image demonstration time that the message in is paid close attention to surpasses the permission time and the prompting user forwards the demonstration of 2-D image to.Some processing can be handled by any one and replace, and some of them are handled and can be merged.For example, (1) and (2) can merge, and current display mode is when being switched to the 2-D image and showing, transforming message is displayed on the screen.
Figure 19 B has shown the situation of I=2, when calculating integrated intensity therein when certain speed k of hypothesis is doubled (k=2 α) among Figure 19 A in the above situation.Therefore, integrated intensity time (t2) of reaching threshold value becomes half of t1.Under the adopted situation of method (1), the 3-D image shows that the permission time becomes half shown in Figure 19 A.
In general, integrated intensity (AI) uses 3-D intensity I and 3-D image to show that time t is expressed as follows.
AI＝f(I，t)
Here, suppose that (I t) is the function of I and t to f.In Figure 19, satisfy f (I, t)=k (I) .t.Yet k (I) is the function of I and in Figure 19, supposes k (I)=α .I (α: integer).
Following other functions can be used for f and k; For example, linear function, twice function or other functions, or any other function can be used.Constant m, α, β is determined by test.At α is that the k in the expression formula (I) becomes the monotonic increasing function of I in the above under the situation of true (true).Under k (I) is positive situation, above f in the expression formula (I t) becomes the monotonic increasing function of t.
As shown in figure 19, under the situation that integrated intensity increased with the time, 3-D image-display units of the present invention is that integrated intensity increases certain quantity (s.I) in each certain time interval.The relation of default constant of " s " expression and " s " and α is as follows:
α＝(s/d)
Figure 20 has shown integrated intensity and the relation between the time in the case.For example, show with stopwatch, and have the situation of the 3-D image of 3-D intensity I=1 that its 3-D intensity I per second increases by 3, then d=1 and s=3 in the time.
The each value that increases a s.I of integrated intensity, the threshold T H in integrated intensity and the 3-D image-display units of the present invention relatively.Under the situation of integrated intensity, continue current 3-D image and show less than TH.Surpass under the situation of TH in integrated intensity, carry out any one processing in (1) to (3).
In other words, the display mode of 3-D image-display units can be converted according to the magnitude relationship of threshold value and integrated intensity.For example, suppose that the threshold value that is imported into the 3-D image-display units becomes TH1 at time t1 from TH0.At hypothesis TH1=0, the display mode of 3-D image-display units is no matter the value of integrated intensity how, and is switched to any one processing in above-mentioned (1) to (3) at t1.
As shown in Figure 8, the 3-D image formatted data of 3-D picture material is made of 3-D image control information part that comprises 3-D image mark information I1 and control information I2 and the view data that is made of the data D that is encoded.Control information I2 comprises 3-D_intensity, 3-D__threshold, the information of display_mode and 2-D__picture_select.Here the display mode of mentioning represents to be used to indicate the information of display mode, therein 3-D image-display units display image data when integrated intensity surpasses threshold value.For example, have in above-mentioned (1) to (3) described pattern.
For example, in the situation of integrated intensity below threshold value (TH＞0), current display mode is held.In the situation of integrated intensity above threshold value (TH 〉=0), current display mode is switched to another.In TH＞0 o'clock, 3-D view data creator, view data supplier or the like can not control the time that integrated intensity surpasses threshold value.Yet, be 0 situation in threshold value, when display unit obtains threshold value 0, integrated intensity always surpasses this threshold value.Therefore, 3-D view data creator, any one can both control the display mode of 3-D image-display units under these circumstances among view data supplier or the like.In other words, can from following modes, select the appropriate display pattern.
(1) current display mode is switched to the 2-D display mode from the 3-D display mode.
(2) keep current 3-D image to show, reduce parallax and alleviate user's eye fatigue.
(3) on screen, show alert message such as " stop rapidly 3-D image show protect you to avoid eye fatigue ".
3-D view data creator, view data supplier or similar people etc. can arrive any one of (3) for 3-D image-display units designated mode (1) in 3-D image control information part.For example, under the situation of designated mode (1) in advance, when display unit was received threshold T H=0, pattern was switched to the 2-D image display mode.
Do not specify display mode to be input under the situation of this unit in 3-D image control information part or user's request, display unit uses preset display mode or specifies display mode to come the target image data by the user.
Selecting under 2-D display mode and the 2-D display image selection information indication eye image data conditions, the eye image data are used to display-object 2-D image.Under the situation of selection information indication left eye image data, left eye image data is used to show the 2-D image.
As described in the first embodiment of the invention, 3-D image control information part can be inserted in any position of 3-D image formatted data repeatedly, so that 3-D view data creator, view data supplier or similar people etc. can reset to 0 (changing display mode) to threshold T H in any position of 3-D image formatted data.
For example, Fig. 9 has shown the example that receives the broadcasting wave of 3-D picture material.In the broadcasted content that constitutes by a plurality of program arrangement information fragments and a plurality of 3-D picture material, the program arrangement information comprises 3-D image control information part (control information I2), and threshold T H can be inserted in the formatted data when inserting the program arrangement information at every turn.Thereby at this moment threshold T H can be reset is 0.For example, be under the situation of (1) at display mode, the 3-D image-display units can switch to the 2-D display mode to display mode.
And, as described in first embodiment of the invention, as shown in Figure 8,3-D image control information part can be inserted in the view data part.In this case, the display mode of 3-D image-display units can be converted for each frame.
The control information of 3-D image also can not only be inserted in the broadcasting wave, also can be inserted in by cable, in the 3-D picture material such as network of internet or the like exchange, also can insert and be recorded in hard disk, CD, or the like the 3-D picture material in.
Figure 21 has shown 3-D intensity, integrated intensity, and 3-D shows another example that concerns between the permission time.In this example, suppose that advancing the speed of integrated intensity is being identical when the 3-D intensity I is 1 and between when it is 2, and threshold T H is different between them.In other words, when TH=1 is used to I=1, and TH2 (half of TH1) is when being used to I=2.Therefore, in the situation of I=1, integrated intensity I reaches threshold T H at t1.In the situation of I=2, integrated intensity reaches threshold T H at t2, and t2 is half of t1.When integrated intensity reached threshold T H, the 3-D image-display units was carried out any one processing in (1) to (3).
Thereby even when different threshold values is used to different 3-D intensity levels, the present invention also can reach the purpose of this embodiment.
Next, explanation is being shown under the situation of a plurality of 3-D image quilts with different 3-D intensity levels continuously, how to limit 3-D and show.
Figure 22 has shown the relation between demonstration time and the integrated intensity.In this example, the 3-D image with 3-D intensity I=1 is shown between time 0 and time a respectively.Then, the 3-D image with 3-D intensity I=3 is shown between time a and time b respectively, and the 3-D image with 3-D intensity I=3 is shown after time b and time b respectively.In this, integrated intensity increases between time 0 and time a with slope k=2 α, increases between time a and time b with slope k=α, and increases after time b and time b with slope k=3 α.THm represents threshold value, and when integrated intensity reaches the time c of THm, can carry out above-mentioned processing (1) any one in (3).
Selecting to handle under the situation of (1), the 3-D image-display units switches to 2-D to display mode at time c and shows.After this, although do not describe in detail, in this embodiment, as shown in Figure 22, display unit reduces integrated intensity with certain speed and recover initial 3-D demonstration when integrated intensity reaches 0 after time c and time c.
Figure 23 has showed the module map of 3-D image-display units among this embodiment.
3-D image control information generation device 2301 is from 3-D intensity and threshold value generation 3-D image control information part as shown in Figure 8.For example, 3-D intensity is got the integer between 1 to 4, and it is represented by 2 bit variable " 3-D_intensity ".Threshold value is got the variable between 0 to 65535, and it is represented by 16 bit variable " 3-D_threshold ".These item of information supposition are encoded as fixing or variable-length.And, be encoded as under the situation of variable at them, suppose and can use the huffman coding method, arithmetic coding method or similar method or the like.
3-D picture coding device 2302 uses such as JPEG or similar still image coding method, or comes raw image data is encoded such as MPEG or similar method for video coding.Suppose that raw image data is to be made of eye image data and left eye image data.Eye image data and left eye image data are narrowed down respectively, merge then to obtain destination image data right and a left side.These processing are here carried out as preliminary treatment.Except using JPEG, outside the image compression of MPEG or the like, also include the expression of bitmap and computer graphical here in the encoding process of mentioning.
Set composite (multiplexing means) 2303 is by the target data and the compound acquisition 3-D of the 3-D image control information part image formatted data that are encoded.In this, the control information of 3-D image also is inserted in the 3-D image formatted data.This insertion method obtains explanation with reference to Fig. 8 and Fig. 9, therefore omits its details here.Compound 3-D image formatted data is stored in the recording medium, or sends to transmission medium.
Like this, the information of representing the 3-D intensity of each 3-D image and threshold value is stored or is sent out with the data that are encoded of 3-D image.
Figure 24 has shown the module map of 3-D image-display units among this embodiment.
Separate the 3-D image formatted data that set composite 2401 input is stored in recording medium or is sent to transmission medium, and be data separating data and the 3-D image control information part that is encoded.
3-D picture decoding apparatus 2403 obtains the decoded view data of target to the data decode that is encoded.Suppose that decoded view data is made of eye image data and left eye image data.As mentioned above, the 3-D picture decoding apparatus also is separated into eye image data and left eye image data here.
3-D image control information analytical equipment 2402 is analyzed the control information of 3-D image and is partly come 3-D intensity and threshold value decoding.For example, display unit obtains as 2 bit variable " 3-D_intensity " of 3-D intensity level with as 16 bit variable " 3-D_threshold " of threshold value.
Then, device 2402 represents that the information of 3-D intensity and threshold value decodes to the above-mentioned data that are encoded with each 3-D image being used to of storing or receive.
Figure 25 A has shown the module map of 3-D image-display units in this embodiment.Display unit uses in the method for above-mentioned processing (1) in (3), limits the 3-D demonstration with 3-D intensity and threshold value.
Display control unit 2501 calculates integrated intensity according to 3-D intensity, and as described below, according to the control of the comparative result between integrated intensity and threshold value 3-D image processing system 2502,2-D image processing system 2503, switch 2504 and display unit 2505.
In the situation of integrated intensity value under threshold value, display unit operation 3-D image processing system 2502 forms the 3-D image that is shown, and stops 2503 work of 2-D image processing system.Switch 2504 is connected to 3-D image processing system 2502, thereby the 3-D display image is sent to display unit 2502.Then, display unit is set to the 3-D display mode to display unit 2505 and shows the 3-D display image.
Surpass threshold value in integrated intensity, and 3-D shows that just as under the confined situation in (1) display unit operation 2-D image processing system 2503 forms the 2-D display image and withdraws from the work of 3-D image processing system 2502.Switch 2504 is connected to 2-D image processing system 2503, thereby the 2-D display image is sent to display unit 2505.Display unit is set to show the 2-D display image to display unit 2505 then in the 2-D display mode.
Surpass threshold value in 3-D intensity, and 3-D shows that the work of 3-D image processing system 2502 is with the same when integrated intensity is under threshold value just as under the confined situation in handling (2).The mode of operation of display unit 2501 conversion 3-D image processing systems 2502, and 3-D image processing system 2502 uses said method to form the 3-D image with low parallax.
When as mentioned above, when identical display mode was used to two threshold T H＞0 and TH=0, display mode can be pressed following description, the degree of the eye fatigue that is caused by the 3-D view data according to the user and control neatly.
When 3-D view data creator or view data supplier conclude that user's eyes are not subjected to very big influence of 3-D view data, can usage threshold TH＞0, and also display mode can be in (1) to (3) any one.When 3-D view data creator or view data supplier conclude that perhaps user's eyes can be subjected to very big influence of 3-D view data, can adopt threshold T H=0, and display mode only is limited to (1), and is transformed into the 2-D display mode immediately.Merge threshold value and display mode and also allow such control method.
In the above example, the view data that is used for 2-D image processing system 2503 is selected information according to the 2-D display image and is switched between eye image data and left eye image data.Yet,, use the view data that is provided with using eye image data or left eye image data to be set in advance under the situation at display unit.Here also use the view data of in the 2-D image display mode, using.
When changing the 3-D image display mode of Set For Current in the 3-D image-display units, view data creator, no matter view data supplier or similar people etc. can be set to 0 by threshold T H in the control control information I2 of 3-D image control information part, change pattern at any time and the state of 3-D image-display units.
Surpass threshold value in 3-D intensity, and 3-D shows that display unit 2505 is substantially just as show alert message when integrated intensity is under threshold value just as under the confined situation in the superincumbent processing (3).
How to form 3-D display image and 2-D display image, and first identical described in the 3rd embodiment of the present invention, therefore should explanation in this omission.
In the above example,, when carrying out any one that handle (1) to (3), can prepare a plurality of contents processing collection in advance, suitably adopt any one collection wherein when integrated intensity reaches threshold value.For example, can pre-defined following processing collection.
A: carry out and handle (1).
B: carry out and handle (2).
C: carry out and handle (3).
D: carry out and handle (1) and (3).
E: carry out and handle (2) and (3).
And, be used to specify collection A and be included in the 3-D image control information part to any one information among the E.Therefore, the information S that is used for representing top processing collection is stored or sends with the data that are encoded of each 3-D image of 3-D image-display units, the 3-D image-display units information S decoding, and is selected the processing that is performed according to information S when integrated intensity reaches threshold value then.
Next, the method for integrated intensity and threshold value will be used to proofread and correct in the explanation 3-D image-display units.Even above method when showing identical 3-D image on the display unit with different qualities (show size, viewing distance, or the like), the characteristic of tube display device is not used identical 3-D intensity and threshold value yet.Yet in fact, user's eye fatigue and for example display screen size or viewing distance grow proportionately and are considered to nature.3-D intensity and threshold value all should be proofreaied and correct according to the characteristic of display unit.For example, have as standard display screen size in order to provide, the display unit of these standard feature of viewing distance or the like should be determined the 3-D intensity and the threshold value that are stored or are sent out with the view data that 3-D is encoded, (standard 3-D intensity and standard gate limit value) best.Thereby each display unit comes calibration standard to show intensity and standard gate limit value according to the characteristic of this display unit.
In order to realize such bearing calibration, the means for correcting 2506 shown in Figure 25 B is connected to the importation of the display control unit 2501 in the 3-D image-display units shown in Figure 25 A.Means for correcting 2506 calibration standard 3-D intensity (In) and standard gate limit value (THn) are also exported calibrated standard 3-D intensity (I) and calibrated standard gate limit value (TH) respectively.I and TH are generally provided by following correction function G and H according to the characteristic of display unit.
I＝G(In)
TH＝H(THn)
Correction function can be expressed as follows by linear function, for example.
G(In)＝N1.In+N2
H(THn)＝N3.THn+N3
N1 is the value that is found by test to N3, or the like.More briefly, only proofread and correct THn below and just may find I and THn.
I＝In
TH＝N.THn
It also is possible only proofreading and correct In.
In above-mentioned expression formula, the viewing distance of the display unit of display unit is identical with the standard viewing distance.Under the situation of display screen overgauge display screen, N gets than 1 little value.Under the situation of display screen less than the standard display screen, N gets than 1 big value.
As mentioned above, although in the 4th embodiment, the 2 visual point image data that employing is made of left eye image data and eye image data, obviously, just as in first embodiment, execute the multi-view image data that example also can adopt the view data by three or more viewpoints to constitute for the 4th real.
Next, describe the processing of when integrated intensity (AI) reaches threshold T Hm, carrying out in detail.Handling (1) to (3) also is the object handles that is performed at this.At first, the processing (1) that how the 3-D display mode is converted to the 2-D display mode is described.
Be transformed at the 3-D image display mode under the situation of 2-D display mode, alleviated user's eye fatigue.Thereby recovering 3-D when the user fully recovers from eye fatigue shows.
Switch to the 2-D image show can be finished automatically or method (3) (explanation in the back) can be used automatically with method (1) or alert message be shown the back by the user manual forward new display mode to.In the following description, suppose that display mode is automatically switched to the 2-D image display mode.
3-D image-display units of the present invention can restart the 3-D image by following situation and show.
(a) restarting object 3-D image after arriving Preset Time (Tm) shows.
(b) show the 2-D image by the time, reduce integrated intensity (AI) at each Fixed Time Interval.When integrated intensity (AI) when dropping to preset value, restart the 3-D image and show.
(c) when the user the 2-D image show and the 3-D image show between during with manual switchover, restart the 3-D image and show.
In any one of situation, the initial value of integrated intensity (AI) can be identical with (f0:f0=(f1,0)) when top 3-D image shows beginning when the 3-D image shows beginning in the above.Otherwise this initial value should be got predetermined threshold value, and (THs:f0＜THs) and can limit the 3-D that restarts and show the time shortens 3-D and shows the time so that restart the back in demonstration.The THs value is determined by test.Under the situation that the switching between demonstration of 3-D image and the demonstration of 2-D image is repeated, the THs value can be modified according to number of repetition.
Under the situation of employing method (a), the Tm value is also determined by test.Under the situation that the switching between demonstration of 3-D image and the demonstration of 2-D image is repeated, the Tm value can be modified according to number of repetition.Get at Tm under the situation of big value,, forbid that still long-time 3-D image shows although user's eye fatigue is fully recovered.Get little value at Tm and accelerate to restart under the situation of original 3-D image demonstration, user's eye fatigue can not fully be recovered.Thereby THs must get bigger value, makes the demonstration of 3-D image restart back 3-D image and shows shorter.This is that the combination of why Tm and THs value can be revised according to user's taste.
Next, the situation of employing method (b) will be described.When the 2-D image was shown, integrated intensity (AI) used following expression and 2-D image demonstration time T to represent.
AI＝THm.g(t，THm)
THm is a function of representing integrated intensity when the 2-D image shows beginning, and g is the function of expression integrated intensity minimizing value.
As mentioned above, function g represents the minimizing value of integrated intensity, and in other words, how many this value representation users recovered from eye fatigue.Function g is also determined by test.In the following description, suppose to use following 2-D image to show the monotonically increasing function of time t.
G (t, THm)=γ .t (γ: positive constant)
Under the situation of T＞THm/ γ, suppose as follows.
g(t，THm)＝THm
Under the situation of the example shown in Figure 22, integrated intensity (AI) reaches expression 3-D and shows the threshold T Hm that allows restriction, thereby display mode is switched to the 2-D image display mode.In the 2-D display mode, integrated intensity (AI) reduces with fixed speed, and 2-D image demonstration continuation, and (AI) reaches 0 up to integrated intensity, and this shows that with first 3-D image the initial value of (between the time 0 to c) is identical.After this, being restarted the 3-D image at time d when integrated intensity AI reaches 0 shows.Similar with the example shown in Figure 26, when the time " e ", integrated intensity (AI) reaches threshold T Hs, restarting the 3-D image shows, after restarting, shorten the 3-D image and show the permission time, and can be shortened the time in the interval between e and the d up to the demonstration of 3-D image by the time that needs till restarting.
Be used to represent the function g of top integrated intensity minimizing value, not only when integrated intensity (AI) reaches 3-D image demonstration permission restriction, also have as the user to show that from the 3-D image switching to 2-D image and displaying contents shows when switching to the 2-D image from the 3-D image significantly, may be used to calculate the integrated intensity (AI) during the demonstration of 2-D image.
Next, the situation of the method (c) above adopting is described.In this case, user's device that uses a teleswitch and so on shows that from 2-D switching to 3-D shows to display mode significantly.Because user oneself judges his/her eye fatigue, this method has the advantage of protecting the user to avoid eye fatigue neatly.This is because how many what and recoveries of eye fatigue vary with each individual.Yet under the situation that this method is adopted by the mode with mistake, this method may seriously influence user's eyes.In order to prevent such problem, display mode only surpasses preset value when the 2-D demonstration time, or uses integrated intensity (AI) that the method identical with (b) calculate just can be switched to the 3-D demonstration when being reduced to predetermined threshold value below in 2-D shows.And still under Preset Time, perhaps integrated intensity (AI) is under the situation on the predetermined threshold value at lapse of time, and alert message can be displayed on the screen, shows to notify the user not allow to switch to 3-D.
Next, describe in detail when accumulation (AI) reaches threshold T Hm, how to carry out top processing (2), reduce its parallax and continue the 3-D demonstration.In this case, reduce parallax, continue thereby allow 3-D to show to alleviate the burden of eyes of user.Top method (2) is used to adjust parallax.The parallax adjustment can be finished or be used top method (3) and method (2) to come together to show alert message one time automatically, adjusts automatically then or by user's manual adjustment.The parallax adjustment can be worked as when integrated intensity (AI) reaches threshold T Hm and only carried out once, also can be for integrated intensity (AI) is provided with new threshold T Hm1, and THm2 ..., THmn, the parallax adjustment is that parallax gradually reduces according to each new threshold value.As shown in the example in Figure 27, after this parallax method of adjustment, the 3-D intensity level can reduce according to controlled parallax value, is used to calculate integrated intensity (AI) then.For example, in Figure 27,3-D intensity is that the displaying contents of I=4 reaches THm in each integrated intensity (AI), THm1, and THm2 ... and progressively adjust parallax during THmn.And 3-D intensity (I) is also as I=3, I=2 and I=1 continuous being changed like that.Because the parallax adjustment is so progressively finished, suppressed the presumable unconformable sensation of user.
Next, describe in detail when integrated intensity (AI) reaches threshold T Hm, how to show the alert message of (3).In this case, not only surpassed the message that 3-D shows the restriction that allows, and given a warning by opening warning LED light of on display unit, being equipped with and so on by expression.Such warning situation also can be notified the user with warning.Warning can only be sent when integrated intensity (AI) reaches thresholding THm, also can send continuously or off and on, stop up to the 3-D demonstration, for example work as the user display mode is switched to 2-D from 3-D significantly, or after being switched to another channel at channel, the display mode that is shown content is switched to the 2-D image when showing.Before integrated intensity (AI) reaches threshold T Hm, might show that also 3-D shows that how many permission restricted T Hm reached (for example, 100.AI/THm).In addition, in case current 3-D shows is stopped, before Preset Time arrives, open again then the time, can give a warning.Up to arriving Preset Time, the operation that switches to the 3-D display mode that the user is obvious is invalid, afterwards, can be shown up to the remaining time of recovering the 3-D demonstration.Similarly, even when the integrated intensity of calculating in the 2-D display mode in front (AI) surpasses to restart in the state of predetermined threshold value when showing, initial 3-D also can give a warning.Under integrated intensity (AI) surpassed the situation of predetermined threshold value, it was invalid to make the user significantly arrive the switching of 3-D display mode, and is shown to the remaining time that allows the 3-D demonstration.
Describe in detail above, carry out to handle (1) to (3) when integrated intensity (AI) reaches threshold T Hm, can only carry out processings (1) in (3), perhaps handling (1) to (3) merging to obtain same effect.Handling (1) under (3) merged situation, the threshold T Hm of integrated intensity (AI) can be in all processing (1) to the common value between (3), or each independent values in handling.
As mentioned above, the 2 visual point image data that are made of right eye and left eye image data are used to illustrate the 4th embodiment.Yet obviously, the three or more viewpoints by view data the 4th embodiment also can be applied in first embodiment constitute the multi-view image data.
Next, the 5th embodiment of the present invention will be described.
3-D image-display units among the 4th embodiment uses the threshold value of 3-D intensity and integrated intensity value as the 3-D image control information that is associated with the 3-D image that is reproduced.The 3-D image formatted data F1 that uses in first embodiment comprises and watching continuously and listening period TIME1 and TIME2.The 5th embodiment handles 3-D video image and the control information of 3-D image is recorded on the digital video tape record cell of one of recording method that comprises the 3-D image control information of these time T IME1 and TIME2 as record.
At first, how the track part that explanation is used for the digital video tape of record data in this 5th embodiment formats.In general, the digital VTR of each current trend adopts a kind of helical form scan method that is known as.The discontinuous track part identifying recording layer of this method on tape.Figure 28 has shown data and how to be recorded on this discontinuous track part.Tape has a plurality of track parts 2801, and 3-D image is cut apart and is recorded on a plurality of track parts.
Figure 29 has shown one extended view in the track part 2801 among the 5th embodiment and has been used for the example of track part form of the digital VTR of record data.Each track part 2801 comprises ITI (Insert and Track Information, insert and track part information) zone 2901, the audio recording zone 2902 that is used for recording audio data, be used for the image-recording region 2903 of recording image data and be used to write down subcode posting field 2904 such as related informations such as timing codes.Image-recording region 2903 can not only write down the 3-D image, can also write down the information that is associated with these 3-D images.Similarly, audio recording zone 2902 can not only recording audio data, also can write down the information that is associated with these voice datas.Except these two zones, subcode posting field 2904 can write down above-mentioned related information.And, between these zones, provide stay white so that each zone all allows additional record.
Figure 30 has shown the extended view of image-recording region 2903.Image-recording region 2903 comprises preamble (pre-amble) signal 3001 that is used to write down synchronous pattern etc., be used to write down VAUX (the Video AUXiliary data of the information that is associated with image, image auxiliary data) α 3002 and VAUX β 3004, be used to write down the Imagery Data Recording zone 3003 that is encoded of the view data that is encoded, error-correcting code 3005 and having is obtained back (post-amble) signal 3006 synchronously that stays white function.Be split into VAUX α 3002 and VAUX β 3004 although be used to write down the zone of the information that is associated with image in the 5th embodiment, these two zones are merged into a VAUX zone, and the zone that hereinafter will merge is called the VAUX district.
Although here do not show, audio recording zone 2902 also has AAUX (Audio AUXiliary data, the data audio ancillary) zone that is used to write down the information that is associated with voice data.
Next, with reference to Figure 31 the 5th record cell among the embodiment is described.Figure 31 has showed the module map of record cell among the 5th embodiment.As shown in Figure 31, this record cell comprises 3-D image encoding part 3101, audio coding part 3102, related information coded portion 3103, composite portion 3104 and magnetic recording part 3105.
3-D image encoding part 3101 input 3-D view data.Although the 3-D view data is made of the view data of a plurality of channels, in the 5th embodiment, 3101 of 3-D image encoding parts are the view data of left eye image data (left image) and two channels of eye image data (right image) input.3-D image encoding part 3101 left-eye image and eye image are merged and with the method for presetting merged image encoding, export the 3-D view data that this is encoded then.
Related information coded portion 3103 is the information such as the merging method that is used to merge a left side and right image in the 3-D image encoding part 3101, the 3-D strength information, the integrated intensity threshold value, the related information coding of permission time that continues to watch and listen to or the like is exported the data behind the coding of related information then.Above coding method here be used for data are converted to fixed-length value corresponding to each above-mentioned information segment.
The composite portion 3104 input 3-D view data that is encoded, the information of the merging method of selecting for merging work, the voice data that is encoded, data with the related information that is encoded, compound data then so that it is stored on the tape, then the compound back data output that will be recorded in tape.
Next, composite portion 3104 obtains more detailed description with reference to Figure 32.As shown in Figure 32, composite portion 3104 comprises related information coded data distribution part 3201, image-recording region data assembling section 3202, audio recording area data assembling section 3203, subcode posting field data assembling section 3204 and track part assembling section 3205.
Related information coded data distribution part 3201 is imported the coded data of related informations and in the VAUX zone, is determined the target area in AAUX zone and the subcode zone, then data is distributed in this zone that is determined.In the 5th embodiment, the data that are encoded of the information that is associated with the merging method of a left side and right image are distributed to the VAUX zone, and with 3-D intensity, the integrated intensity threshold value continues to watch and listens to allow the information of time correlation connection to be distributed to the subcode zone.
3202 inputs of image-recording region data assembling section are from the 3-D coded image data of 3-D image encoding part 3101 outputs and the VAUX zone association information coded data of exporting from related information coded data distribution part 3201.Image-recording region data assembling section 3202 is merged into as shown in Figure 30 formative data slot to these data.This related information for example is included as from the information of the merging method of selecting for right and left image of 3-D image encoding part 3101 outputs.Then, preamble 3001, error-correcting code 3005 and postamble 3006 add in the related information, so that export this image-recording region data.
3203 inputs of audio recording area data assembling section are from the voice data that is encoded of audio coding part 3102 outputs, with the data that are encoded, and these data are merged become the default formatted data that will be output to the audio recording zone from the AAUX zone association information of related information coded data distribution part 3201 outputs.
Subcode posting field data assembling section 3204 is imported from the data that are encoded of the subcode zone related information of related information coded data distribution part 3201 outputs, and this data merging is become the formatted data of presetting that will be output to the subcode posting field.
3205 inputs of track part assembling section are from image-recording region, the data of audio recording zone and subcode posting field, and these data are merged into as shown in Figure 29 formatted data, then ITI information 2901 with interregionally stay white adding in the merged data that will be output and write down.
As mentioned above, in this embodiment, data are recorded in all audio recording zones simultaneously, in image-recording region and the subcode posting field.Yet data also can be recorded in all these zones simultaneously.Data can only be recorded in some zones, for example, at first have only audio recording zone and image-recording region, and data can be recorded in the subcode posting field by additional record then.Even after data are recorded in all these zones, other data also can be covered in each zone independently by additional record.
3-D strength information, integrated intensity threshold value and continuing are watched and listened to the permission time can be according to the result of the last content that is determined when taking at last usually, definite in the editing process of taking after finishing.For example, view data can be recorded under the situation of 3-D intensity=1 as default value during shooting, judges in the objective evaluation in editing process that then this view data is additional record under I=2 under the high situation of 3-D strength ratio default value.In the record cell of the 5th embodiment, the 3-D strength information, integrated intensity threshold value and continue to watch and listen to the permission time and be recorded in the subcode zone, additional record can be finished thereon more like a cork, even so that also can revise these items of information like a cork in the editing process Shen.
Though as mentioned above, in these five embodiment, the 3-D strength information, the integrated intensity threshold value, be recorded in the subcode zone with continuing to watch and listening to the permission time, these items of information can be merged into one and be recorded in the VAUX zone, because all these items of information are counted as being associated with image.
In order to realize such method, revise the work of the related information coded data distribution part 3201 shown in Figure 32, make the data that are encoded of all above-mentioned items of information output to the VAUX zone.In this, the information that is associated with image is collected in a place, so that handle these items of information more like a cork, although this moment, additional record was just no longer light.For example, when view data is copied to the medium with different recording formats, under the situation of the content in needing only the copy image posting field, will obtain the item of information that all are associated with image, thereby can omit the subcode zone.And, being added record for fear of view data and covering, view data can be stored in subcode zone and the VAUX zone.
Subcode zone and VAUX zone storage capacity separately are limited.Therefore, under the situation among view data can not all be stored in these zones any one, the information stores that can be associated the 3-D image is in the AAUX zone.
Some digital VTR machines provide the cartridge memory that is used for recording-related information respectively.Thereby above-mentioned related information can be stored in this memory.
Related information also can be recorded in the memory of unit.In this, in superincumbent description, posting field can comprise image-recording region, audio recording zone and subcode posting field, and 3-D image display control information or shooting condition information also can be recorded in these zones.
The configuration of the record cell of the 5th embodiment except specific be the part of 3-D image, the digital VTR method that also is adapted to home video tape recording and is adopted.Therefore, the related information item that writes down among the 5th embodiment has the related information that aims at the 3-D image that is recorded as household digital VTR form, for example, relate to the item of information that how to merge right and left image, the 3-D intensity level, the integrated intensity threshold value continues to watch and to listen to permission time or the like passable.Thereby 2-D can both be recorded on the identical tape with the 3-D image.
Yet, in the 5th embodiment of the present invention, data sender, 3-D image creator for example, the broadcasting station, or content supplier (hereinafter simply being called supplier or the like) forces to specify in the time that beginning 2-D shows in the target 3-D view data.Hereinafter, such designation method is described.
As shown in Figure 8, the 3-D image formatted data F1 of 3-D picture material also has the view data part that is made of the data D that is encoded to constitute by the 3-D image control information part that comprises 3-D message identification information I1 and control information I2.In this embodiment, as shown in figure 33, control information I2 comprises forces 2-D show label (force_2-D_display_flag) and 2-D display image to select information (2-D_picture_select).Whether order the 3-D image-display units to force to forward to the 2-D display mode when forcing the 2-D show label to represent to show the 3-D view data.The 2-D display image selects information representation when display mode is forced to switch to the 2-D image according to the value of forcing to be provided with in the 2-D show label, shows eye image data or left eye image data.When the 3-D view data was shown, the 2-D display image selected information inoperative.
For example, forcing the 2-D show label to be set under 1 the situation, display mode is forced to switch to the 2-D image and shows.Select information to represent at this moment under the eye image data conditions at the 2-D display image, just with eye image data display object 2-D image.Select at the 2-D display image under the situation of information representation left eye image data, just with left eye image data display object 2-D image.
Forcing the 2-D show label to be set under 0 the situation, display mode is not forced to switch to the 2-D image and shows.There are many methods to realize this operation.First method is to continue current display mode.For example, under the current situation about being set up of 3-D image display mode, it is constant to keep this pattern.Under the current situation about being set up of 2-D image display mode, it is constant to keep this pattern.Second method is to specify the 3-D image display mode regardless of current display mode.The 3rd method is used for selecting 3-D or 2-D image display mode under other conditions.For example, also not arriving under the 3-D image situation of demonstration permission time, the 3-D image display mode is set.Arriving under the 3-D image situation of demonstration permission time, the 2-D image display mode is set.Press the button under the situation that switches to another display mode the user, selecteed display mode is set.Can between 3-D image encoding apparatus and decoding device, pre-determine which kind of method of employing.
As described in first embodiment, 3-D image control information part can be repeated to be inserted into any position among the 3-D formatted data F1.3-D view data creator, view data supplier, or similar people etc. can be arranged on for 1 (switching to the 2-D image shows) forced in the 2-D show label in any position among the 3-D image formatted data F1.
For example, Fig. 9 has shown the example of broadcasting 3-D picture material, and under the situation that broadcasted content is made of a plurality of program arrangement information fragments and a plurality of 3-D picture material, the control information of 3-D image partly is included in the proceedings information.At this moment, be inserted into 3-D image formatted data F1 when the program arrangement information, forcing the 2-D show label to be set under 1 the situation, be set to the 2-D image display mode in the display unit of receiving terminal.
And described in the embodiment on the present invention, 3-D image control information part can be inserted in the view data part shown in Figure 33.In this, the 3-D image-display units can force to be set to the 2-D image display mode for every frame.
Such 3-D image control information also can be inserted in the 3-D picture material that is exchanged by network and cable such as the internet, is recorded in addition such as hard disk, in the 3-D picture material in the recording medium of CD etc.
Figure 34 has shown the 3-D picture coding device 2003 and the decoding device 2004 that is used for information decoding that is used to format 3-D image formatted data F1.
In Figure 34, the time that 3-D view data creator or view data supplier order the control information of 3-D image to form device 2005 appointment in the 3-D view data of input forces to forward to the 2-D image display mode, and is provided with 1 in the pressure 2-D show label that provides in the 3-D image control information part corresponding to view data.Simultaneously, 3-D view data creator or view data supplier still are the eye image data that the left eye image data information that is used to display object 2-D view data writes in the 2-D display image selection information.And, writing independently with this, 3-D view data creator or view data supplier order 3-D picture coding device 2001 with the 3-D coded image data.Then, the view data that 3-D view data creator or supplier partly are stored in the 3-D view data that wherein storage is encoded to the 3-D image control information that is set to 1 therein in forcing the 2-D show label partly in, or message part and view data part separate storage, thereby form 3-D image formatted data F1.The service recorder medium, by network or broadcasting wave, F1 sends to 3-D picture decoding apparatus 2004 the 3-D image formatted data.
In 3-D image decoding apparatus 2004,3-D picture decoding apparatus 2002 is decoded as the 3-D view data to the 3-D image formatted data F1 that receives, and respectively the pressure 2-D show label and the 2-D display image that are arranged in the 3-D image control information part is selected information decoding then.If show label is set to 1,3-D picture decoding apparatus 2002 is provided with target 2-D image display mode, output mode information then in display mode information.Display mode information is used to order 3-D image-display units (explanation in the back) and switches between demonstration of 3-D image and the demonstration of 2-D image.
If force the 2-D show label to be set to 0, as mentioned above, can former state the output display mode information, can be set to the output of 3-D image display mode in display mode information, or be set to the 2-D image display mode or export according to other conditions 2-D image display mode therein.
3-D view data by 2004 decodings of 3-D picture decoding apparatus is displayed on the screen of the 3-D image-display units shown in Figure 35.The separated device (not shown) of 3-D view data by 2004 decodings of 3-D picture decoding apparatus is separated into eye image data and left eye image data, is input to respectively then in the 3-D image-display units shown in Figure 35.These view data are used as right eye according to display mode information and left eye image data is input to 3-D picture decoding apparatus 2004.Be set in display mode information under the situation of 3-D image display mode, above switch 2101 is pulled to.Be set in display mode information under the situation of 2-D image display mode, below switch 2101 is pulled at this moment.The view data that is imported into 2-D image processing system 2105 is switched to eye image data or left eye image data by switch 2102 according to 2-D display image selection information.The work of 3-D picture decoding apparatus 2004 and 2-D image processing system 2105 is identical with the work of 3-D image processing system 100 shown in Figure 14 and 2-D image processing system 6, so their explanation will be omitted at this.
Established as mentioned above 3-D or 2-D view data are converted to 2-D or 3-D view data by switch 23 according to display mode information, output to frame memory 2106 then.Display unit 2107 is shown as 3-D or 2-D image to the view data of reading from frame memory 2106 according to display mode information.At this moment, the work of frame memory 2106 and display unit 2107 is identical with the work of frame memory 2 shown in Figure 14 and display unit 3, so their explanation will be omitted at this.
In the superincumbent example, the view data that is imported into 2-D image processing system 2105 is selected information to switch between eye image data and left eye image data by switch 2102 according to the 2-D display image.Set in advance at the 3-D image-display units that to use the eye image data still be under the left eye image data situation, the view data that is set up can be input to 2-D image processing system 2105.The view data that past is imported in the 2-D image display mode also can be used at this.
When forcing when the 3-D view data shows that switching to the 2-D view data shows, 3-D view data creator or supplier, be set to 1 by the pressure 2-D show label among the control information I2 in 3-D image control information part, thereby the state that can not consider the 3-D image-display units how, shows and switch the desirable time at him.
