Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a recorded information recording medium disk, particularly for reproduction of simultaneous stereoscopic television video signals, reproduction of sequential stereoscopic television video signals, and , normal televised video signal (
(television video signal used to reproduce non-stereoscopic television images (flat television images))
The present invention relates to a recorded information recording medium disk that is capable of performing the following operations.

(Prior art) In recent years, as high-density recording and reproducing systems using various recording media have been put into practical use, it has become possible to record television video signals (hereinafter referred to as TV). Recorded information recording medium discs (video discs) in various formats are now available.

(Problems to be Solved by the Invention) Video discs using various recording and reproducing methods using various recording media that have been put into practical use up to now all record TV video signals that reproduce 17 flat images. However, recently, the appearance of video discs recording stereoscopic TV video signals has been eagerly awaited.

By the way, as a 3D TV method for displaying 3D images,
Similar to making the viewer feel a three-dimensional image in a three-dimensional movie, the left and right eyes can be seen with each eye to make the viewer psychologically perceive a three-dimensional image. There are two types of 3D TVs that follow the construction principle of
Although several dozen systems are known about each of the simultaneous 3D TV system and sequential 3D TV system, it is well known that 3D TV broadcasting has not yet been put to practical use. That's right.

In order to easily obtain compatibility with the currently widely used TV system for reproducing flat images, the TV video signal for the left eye and the TV video signal for the right eye are broadcast individually. Therefore, if the frequency bands allocated to broadcasting according to the current TV system are allocated, the number of channels allocated to TV broadcasting will be substantially reduced in order to implement simultaneous 3D TV broadcasting. In addition, if band compression means are applied to the TV video signal for the left eye and the TV video signal for the right eye, the TV system itself will be T
What you need to do to make this different from V broadcasting is that if you send a TV video signal for the left eye and a TV video signal for the right eye using the field sequential method, you can send the TV video signal for the left eye and the TV video signal for the right eye. This is because when reproduced on a television receiver, it is reproduced as a double image, which makes it impossible to adopt it, and there are many other problems.

However, the issue of channel allocation that has become a problem in TV broadcasting is irrelevant to video discs, and the TV format to be adopted can be determined with great flexibility, so video discs can be used as a medium for 3D TV. It was considered meaningful to use it.

However, even if the video disc is for playing back a 3D video signal, when it is played back by a video disc playback device that is already in widespread use, normal 2D image playback and normal sound playback cannot be achieved. Of course, it is desirable that the TV video signal for the left eye and the TV video signal for the right eye recorded on the video disc be recorded in a simultaneous format. A left-eye TV video signal and a right-eye TV video signal that can be used to reproduce a stereoscopic image by a stereoscopic TV video signal reproducing device configured to be able to reproduce the same, or that is recorded on a video disc. It is also desirable that the three-dimensional TV video signals be used so that they can be reproduced into three-dimensional images by a three-dimensional TV video signal reproducing device that is configured to be able to reproduce video signals in a sequential manner. There was a demand for the appearance of a video disc that would satisfy the demand.

The video signal for the right eye is recorded alternately every cycle, and the audio signal accompanying the simultaneous stereoscopic television video signal can be played back in various playback modes without any inconvenience. In order to be able to be played back, it is recorded in a special recording pattern as described below, and various control signals as described below that are required during playback operation in a specific playback mode are also described below. It is recorded in this manner.

The recorded information recording medium disc of the present invention is, for example, l1Jl! of the applicant company. When implemented as a recorded information recording medium disc that detects changes in capacitance value, such as a recorded information recording medium disc that can be played back by a player that conforms to the so-called V)10 system, Like the recorded information recording medium disk shown in FIGS. 1 and 2, the recorded information recording medium disk moves from a specific radius position set at the 2-2 line position Four fields of video signals are recorded for each IJ up to the position, and during each vertical blanking period recorded in the recorded portion a near a particular radial position, , a signal indicating the reference rotational phase of the board (hereinafter referred to as signal f

A recording trace is formed by the types of tracking reference signals f pi and f p2 (hereinafter sometimes referred to as signals f pi and f p2), and furthermore, the two types of tracking reference signals described above are The pre-recorded disc of the present invention satisfies the various conditions required for a VHD format video disc, such as the signal being recorded in a state in which the signal is sequentially and alternately switched for each recording position of the signal fp3 described above. It is implemented as a method that satisfies various conditions required for information recording medium discs.

Further, the recorded information recording medium disc of the present invention may be implemented as one that is played back by an optical video disc player, and the recorded information recording medium disc of the present invention may be implemented as one that is played by an optical video disc player. When implemented as a disc, after satisfying the basic conditions stipulated in the standard for optical video discs, the conditions required for the recorded information recording medium disc of the present invention are met. It will be implemented satisfactorily.

In the description of the following embodiments, a case where the recorded information recording medium disk of the present invention is implemented as one that can be reproduced by a so-called Vl (D type recorded information recording medium disk player) will be described as an example. However, in the plane of the recorded information recording medium disk of the present invention shown in FIGS. 1 and 2 and other figures, the tracking reference signal is Illustrations and explanations of the recording traces by f pi and f p2 are omitted.

Now, the recorded information recording medium disc of the present invention has a recording mode as described above with reference to FIGS. video signal and N fields of consecutive video signals for the right eye are recorded in a single spiral on a recorded information recording medium disc that allows one station to record video signals for N fields. Since the left eye video signal and the right eye video signal are recorded on the recorded information recording medium disc as described above, (1 ) If only the left eye (or right eye) video signal is reproduced continuously in the order of field numbers as shown in Figure 3 (or Figure 4), L1 → L2 → L3 → L4 →
L5→L6→・・・・・・(or R1→R2→R3
→R4→R5→R6→...) A video signal for planar image reproduction is obtained by continuation of the video signals of each field, and (2) a video signal for the left eye with an odd field number. and a video signal for the right eye with an even field number (above, a video signal for the right eye with an odd field number and a video signal for the left eye with an even field number) are sequentially and alternately divided into field numbers. If it is played back in sequence as shown in Figure 5 (or Figure 6), L1 → R2 → L3 → R4 → L5
→R6→... (or R1→L2→R3→Shi4→R5→L6→...), the sequence of video signals for each field allows for field-sequential three-dimensional image reproduction. If a video signal is obtained and (3) the video signal for the left eye and the video signal for the right eye with the same field number are played back at the same time, simultaneous three-dimensional image playback can be achieved. In other words, you can obtain a video signal for your computer.

Corresponding to the playback operation in each of the different playback modes (1) to (3), the recorded information recording medium disc of the present invention produces a two-dimensional TV video signal and a field-sequential three-dimensional T.
A V video signal and a simultaneous stereoscopic TV video signal can be selectively reproduced.

By the way, the present invention has a function of being able to reproduce traces of lost data every other round on the recorded information recording medium disc based on a control command signal for the displacement of the reproducing element recorded on the recorded information recording medium disc. By a conventional recorded information recording medium disc playback machine.

When the recorded information recording medium disc of the present invention is played back,
Due to the function of the conventional playback device described above, only the video signal for the left eye (or right eye) is automatically reproduced continuously in the order of field numbers as shown in Figure 3 (or Figure 4). The recorded information-recording medium disc of the present invention and the conventional recorded information recording medium FT'li? can be reproduced.
'YF' is a desirable implementation mode from the point of view of compatibility with its reproducing machine, and the recorded information recording medium disc of the present invention is also suitable for simultaneous stereoscopic TV video signals recorded on it. The field number in the recording trace of one video layer number for the left eye (or the recording trace of the right eye video signal of a simultaneous stereoscopic TV video signal) is mN.
(where m and N are natural numbers) The field number starts from near the end of the recording trace where video signals are recorded (m and N are natural numbers).

A predetermined position II (Y-Y in the figure in the example shown in FIGS. 1 and 2)
Record it at the radial position indicated by (
(Details will be discussed later).

Furthermore, the locus of the reproducing element when reproducing a recorded information recording medium disc as shown in FIG. Sometimes, it will be as shown in the bold line in FIG. 3 (or FIG. 4), and for example, when playing back a field-sequential stereoscopic TV video signal, it will be as shown in the bold line in FIG. 5 (or FIG. 6). Furthermore, for example, when reproducing a simultaneous stereoscopic TV video signal, a specific radial position Vtt set on the recorded information recording medium disk <Z-Z in FIGS. 1 and 2, The information signal is reproduced from the recording trace of the adjacent left eye video signal and the recording trace of the right eye video signal of each one round N field from the position of the line).
The reproducing elements draw trajectories that trace the aforementioned adjacent recording traces in parallel, but as mentioned above, the reproducing element that reproduces the information signal from the recorded information recording medium disc is Even if the position of the displacement near the vertical blanking period varies depending on the playback machine, the playback mode
.

In order to ensure that the audio signal accompanying the video signal is reproduced without any problems, the displacement of the above-mentioned reproduction element recorded on the recorded information recording medium disc during the reproduction operation by the reproduction machine is In order for the audio signal accompanying the video signal to be reproduced without any problems even if the control command signal cannot be read, the editing method for the audio signal accompanying the video signal must be appropriate. Must be.

Next, a mode of editing an audio signal accompanying a video signal in the recorded information recording medium disc of the present invention will be explained.

First, considering the case where a simultaneous three-dimensional TV video signal is reproduced from the recorded information recording medium disc shown in the first figure, the reproducing element that follows the recording trace of the recorded information recording medium disc in this reproduction mode is , because it only traces the spiral record trace into a vortex.

The recording traces on the recorded information recording medium disk include the audio signal L Is accompanying the video signal of each field.

3m- is recorded on each (the same applies to the recorded information recording medium disk shown in the second figure, so in the following explanation, the recorded information recording medium disk shown in the first figure and related thereto will be used as a representative example). The explanation will be given with reference only to the drawings, and the specific explanation of the progress made with reference to FIG. (I will omit the detailed explanation as I am asking you to do so.)

Regarding the display of audio signals, the audio signal accompanying the video signal of the field with field number L1 is Lls, the audio signal accompanying the video signal of the field with field number L2 is L2g, ...the video of the field with field number R1. The audio signal accompanying the signal is expressed as Rb+, but the audio signal accompanying the left eye video signal of the field with the same numbered field number and the right eye video signal are expressed as Rb+. Since the audio signals accompanying the signals are originally the same, the audio signals in the following description and in the descriptions in the figures will be expressed as, for example, 1s, 2s, 3s, without distinguishing between R. may be displayed.

By the way, when a video sales signal for planar image reproduction is to be reproduced from the recorded information recording medium disc shown in FIG.
The reproducing element traces the recording traces on the recorded information recording medium disc shown in the first figure, from L1 to L2 to L3 to R4 as shown in the third figure.
→ L5 → L6... Since it is necessary to trace as follows, the reproducing element is
It is made to be displaced by the record trace interval.

As shown in FIG. 3 above, even when the reproducing element is required to be displaced to the adjacent recording trace at the Z-2 line position during reproduction, the position where the reproducing element is actually displaced is As a matter of course, there will be some variation as shown in FIGS. 7(a) to 7(c), for example, depending on the reproducing machine used for reproducing the recorded information recording medium disk.

First, as shown in FIG. 7(a), each field L4. If the audio signals L4s, Rls, R4s, and L5g accompanying the video signals of R1, R4, and L5 are recorded in correct correspondence with the field sections in which the video signals of the respective fields are recorded, If the displacement position of the reproducing element deviates even slightly from the field switching position (line Z-2 in FIG. 7) toward the field R1 side, the state of the audio signal connection deteriorates at that point.

That is, the audio signal L4s accompanying the video signal.

If the switching positions of Rlg, R4s, and L5g coincide with the field switching positions as shown in FIG. The signal is L4g-)R1s→L
This is because an unnecessary audio signal R1g is mixed in at the time of switching, such as at 5s.

So, in order to prevent the above problem from occurring,
As shown in FIG. 7(b), the audio signal L5g accompanying the video signal of field L5 is recorded in at least the first 7 minutes of field R1 following field L4. do it.

However, the audio signals L4S, R1s accompanying the video signal,
Even if the switching positions of R4s and L5s match the switching positions of the field as shown in FIG. 7(a), the position to which the reproducing element is displaced is as shown in FIG. 7(c). In the case of the field R1 side, the audio signal to be reproduced is L4a → R45 (R4sq = L58:41) → L5g
Therefore, unnecessary audio signals are not generated during switching.

Next, when the stereoscopic TV video signal for the field sequential system is reproduced from the recorded information recording medium disk shown in the first figure, the reproducing element moves the recording trace on the recorded information recording medium disk shown in the first figure. As shown in Figure 5, L1→R2→
Since it is necessary to trace as L3→R4→..., the reproducing element is made to be displaced by one recording trace for each field section. Assuming that an audio signal accompanying the video/video signal of each field is recorded for each field section on the information recording medium disk, the field sequential method can be used from this recorded information recording medium disk. When playing back a 3D TV video signal, even if the position of the playback element is slightly shifted to either side with respect to the switching point, the audio signal played in the shifted state will not be the same as the audio signal that was originally supposed to be played. Since they are the same, when reproducing a field-sequential stereoscopic TV video signal from the recorded information recording medium disc shown in the first diagram, the audio signal recording mode is originally the same as that of the audio signal. There should be no connection problems.

However, when a video signal for two-dimensional image reproduction is being reproduced from the recorded information recording medium disk shown in the first diagram on which an audio signal is recorded in the recording manner as described above, the reproduction element If the reproducing element does not move at a predetermined displacement position due to a failure to read the displacement control command signal, a completely unrelated field audio signal will be generated for about one field period.

Therefore, in the recorded information recording medium disc of the present invention, the editing point of the audio signal is set at a specific position so that the above-mentioned problems hardly occur.

In other words, in the recorded information recording medium disc of the present invention, when it is configured as shown in the first diagram, the recording trace of the right eye video signal of the simultaneous stereoscopic TV video signal is recorded. The audio signals recorded in all fields except the recording section of the first field in the recording section of N fields for each round in sequence are the video signals of the field numbers recorded in each field section. The recording section of the first field in the recording section of N fields for each round in the recording trace of the right eye video signal of the simultaneous stereoscopic TV video signal, which is an accompanying audio signal. The audio signal recorded in the field section is an audio signal that is attached to the video signal of the field number recorded in the Ryeld section near the end of the field section, but the remaining section of the field section The editing point X of the audio signal is defined to be applied to the audio signal accompanying the video signal with the field number recorded in that field section plus N. (see Figure 8), the recorded information recording medium disc of the present invention may be
When configured as shown in the figure, the first field in the recording section of N fields for each round in the recording trace of the left eye video signal of the simultaneous stereoscopic TV video signal. The audio signals recorded in all fields except the recording section are the audio signals that accompany the video signal of the field number recorded in each field section, and are the audio signals that accompany the video signal of the field number recorded in each field section. The audio signal recorded in the recording section of the first field in the recording section of N fields for each successive round in the recording trace of the video signal for the eye is the same as that field near the end of the field section. The audio signal is associated with the video signal of the field number recorded in the field section, but the remaining section of the field section contains a field that is the field number recorded in that field section plus N. The editing point of the audio signal is set in the same way as is done for the audio signal accompanying the video signal of the number (see FIG. 9).

When a recorded information recording medium disk is played back with a playback machine,
As mentioned above, the control command signal for the displacement of the reproducing element is recorded so that the video signal for reproducing the planar image is reproduced from the recorded information recording medium disc. The following two types of displacement control command signals are recorded.

That is, as the control command signal for the displacement of the reproducing element described above, the recording trace of the left i video signal of the simultaneous stereoscopic TV video signal recorded on the recorded information recording medium disc, and the simultaneous stereoscopic TV video signal recorded on the recorded information recording medium disc are used. One of the predetermined recording traces (first
Regarding the recorded information recording medium disc shown in the figure, there are recording traces of left-eye video signals of simultaneous stereoscopic TV video signals,
Regarding the recorded information recording medium holiday fiD shown in Figure 2,
The field number in the recording trace of the right eye video signal of the simultaneous stereoscopic TV video signal is mN (however.

Starting near the end of the recording trace where video signals (m is a natural number) are recorded, the field number is (mN+1...however,

- 1 for the first control command signal for the displacement of the reproducing element described above.
And the 2nd man etc. are us in the second control command signal of the displacement of the reproduction element. When the signals are read by the playback elements -P and Q and given to the playback device, they are read in a predetermined direction with respect to the playback element (from the outer circumference side to the inner circumference side of the recorded information recording medium Day 1!D). It is configured to include displacement control information for performing displacement for one recording trace interval.

That is, regarding the first control command signal 7 for the displacement of the reproducing element to be recorded on the recorded information recording medium disk t shown in FIG. 1, for example, the field section of field number Ll The first control command signal for the displacement of the reproducing element recorded at the start end of 1 can displace the reproducing element to the candy 1 of the field section of field number L5 at the end of the field section of field number L4. For example, the first control command signal Kl for the displacement of the reproducing element recorded in the starting end of the field section with field number L5 is configured to include displacement information such as that in field number L8. At the end of the section, the reproducing element is displaced to the field of field number L9 - the beginning of the section, and the reproduction element including the displacement information M
The first control command signal for the displacement of the reproducing element is set to 1, and on the other hand, the recorded information recording medium disk shown in FIG. Regarding the first control command signal Kl of the displacement of the reproducing element to be recorded in, for example, the field number R
The first control command signal Kl for displacement of the reproducing element recorded at the starting end of the field section No. 1 displaces the reproducing element to the starting end of the field section having field number R5 at the end of the field section having field number R4. For example, 1 in the first control command signal for the displacement of the reproducing element recorded at the starting end of the field section with field number R5 corresponds to field number R8. The first control of the displacement of the reproducing element is configured to include chapter position information that allows the reproducing element to be displaced to the starting end of the field section of field number R9 at the end of the field section of field number R9. 1 is configured in the command signal element, and when a video signal for planar image reproduction is being reproduced from the recorded information recording medium disc, the reproduction element is configured as described above.
When 1 is correctly read in the first control command signal for the displacement of the reproducing element having a displacement, the reproducing machine moves the reproducing element at the z-2 line position in Figs. It moves and operates so as to be displaced in the inner circumferential direction. The above-mentioned operation in the reproducing machine is the first displacement of the reproducing element described above.
When the control command signal of 1/ is given to the reproducing machine, the change included in the first control command signal of the displacement of the reproducing element.

According to the position information, for example, a kick pulse may be applied to an actuator of a tracking control system to displace the reproducing element by one recording trace distance wk in a predetermined direction.

Next, regarding the second control command signal 2 for the displacement of the reproducing element to be recorded on the recorded information recording medium disc shown in FIG. The second control command signal for the displacement of the reproducing element recorded in the section 2 is such that the reproducing element is displaced from the end of the field section of field number R1 to the beginning of the field section of field number L6. It is configured to include displacement information and displacement information that allows the reproducing element to be displaced from the end of the field section with field number L8 to the start end of the field section with field number L9. The second control command signal for the displacement of the reproducing element recorded at the starting end portion of the field section includes a command signal 2 such that the reproducing element can be displaced to the starting end of the field section having the field number LIO at the end of the field section having the field number R5. and displacement information that allows the reproduction element to be displaced from the end of the field section with field number L12 to the beginning of the field section with field number L13.

For example, in the second control command signal for the displacement of the reproduction element recorded at the starting end of the field section with field number L5, 2 is the field number L5. Displacement information that allows the reproducing element to be displaced from the end of the field section of field number RIG to the beginning of the field section of field number RIG at the end of the field section of field number L5, and the starting point between the end of the field section of field number R12 and the field of field number R13. The second control command signal for the displacement of the reproducing element is configured to include displacement information such that the reproduction element can be displaced, and -.

When a video signal for planar image reproduction is being reproduced from a recorded information recording medium disk, when the reproduction element reads 2 in the second control command signal for the displacement of the reproduction element having the content as described above. In this case, the reproducing element fails to read 1 in the first control command signal of the displacement of the reproducing element and is in a state where it is tracking the wrong recording or trace. When 2 is given to the control command signal of 2,
The displacement -11-11- (f-report) included in this immediately displaces the reproducing element onto the recording trace that the reproducing element should originally follow.In other words, the reproducing element In a state where a video signal for planar image reproduction is being reproduced from a recorded information recording medium disk, for example, a second control command signal for the displacement of the reproducing element recorded at the starting end portion of the field section with field number R1. 2, the reproducing device reads the second displacement of the reproducing element, which is configured to include the displacement control information as described above.
According to the control command signal and the displacement control information in step 2, the reproducing element moves from the field section of field number R1 to the field section of field number L6 to the field section of field number L7 to field number 8,..., to the field section of field number L9. In order to be able to trace the recording trace of the recorded information recording medium disk through a path such as field interval → field interval of field number LIO → It is displaced to the starting end of the field section with field number L6, and is also displaced from the end of the field section with field number L8 to the starting end of the field section with field number L9.

Therefore, when reproducing a video signal for planar image reproduction from a recorded information recording medium disc, the reproducing element fails to read 1 in the first control command signal for the displacement of the reproducing element, resulting in an incorrect recording trace. is being tracked, and the second displacement of the reproducing element is
When 2 is read in the control command signal of

Depending on which of the above-mentioned signals is reproduced, it is possible to know which of the recording traces of the left or right eye video signal the reproduction needle is tracking at that time. Extraction circuit KAG (KAGΩ, KAG
When the control command signal for the displacement of the reproducing element extracted in step (r) is 1 in the first control command signal, the recorded information recording medium disc in the embodiment shown in the first figure has a position of radius Y-Y. This means that the playback needle is tracking the recorded trace of the video signal for the left eye, and in the recorded information recording medium disc in the embodiment shown in the second figure, the playback needle is tracking the right eye at the position of the radius Y-Y. This means that the control command signal extraction circuit KAG (KA

After displacing the reproducing element to the outer periphery by one recording trace interval at the blanking period position, the reproducing element is displaced to the inner periphery by one recording trace interval at the vertical blanking period position d on the recorded information recording medium disc. At the same time, a displacement control signal (kick signal or kick pulse) is generated and switched so that the reproducing element is not displaced at the vertical blanking period position a on the recorded information recording medium disc. Pulse generator 5PG (SPG

Next, in the playback device of the embodiment shown in FIGS. 15 and 16, when the operation mode thereof is set to the simultaneous stereoscopic TV video signal playback mode, the movable contact V of the changeover switch SVk is moved to the fixed contact ca side. The mode of displacement of the reproducing needle is the same as that when reproducing the planar image described above. Note that the switching operation of the movable contact V of the changeover switch svh described above is performed when the switching control signal is connected to the supply terminal 16 of the control signal.
, 16 Q , 16 r. The switching control signal for the changeover switch described above is generated by the operator setting the playback mode on the operation section of the playback device.

In the reproducing apparatus of the embodiment shown in FIG. 15, since one reproducing needle S provided with two electrodes is used as described above, only one tracking control system is required, and the tracking control system is The tracking reference signal to be given to the system may be the one read by one electrode on the reproduction needle S (in the example shown, the one that reads the video signal for the left eye of the sparrow) should be used. It is assumed that the tracking reference signal is used in the tracking control system).

In the embodiment shown in Fig. 16, separate reproduction needles are used as the reproduction needle for reading the video signal for the left eye and the reproduction needle for reading the video signal for the right eye. Since there is a time difference between the left and right eye video signals reproduced from the reproduction needle, and they are not simultaneous signals, one of the output video signals (in the example shown, for the right eye) video signals) are delayed by a delay circuit DL to become simultaneous signals.

FIG. 17 shows an example of the configuration of a display used to reproduce both 3D TV images using 3D TV video signals generated by a playback device, and (a) in FIG.

By being supplied,
This figure schematically shows the principle of construction of a display for reproducing a stereoscopic image using a field sequential stereoscopic TV video signal configured so that the viewer 23 can perceive a stereoscopic image.

In Fig. 17 (a) - RA, 18 is a picture tube that projects a reproduced image for the right eye by being supplied with a video signal for the right eye, and 20 is an input terminal 17Ω for the left eye. It is a picture tube that projects a reproduced image for the left eye by being supplied with a video signal for the eye, and further includes a picture tube as shown in FIG. 17(b).
Reference numeral 26 denotes a picture tube for projecting a field-sequential reproduced image when a field-sequential stereoscopic TV video signal is supplied to an input terminal 17.

In the display for reproducing stereoscopic images shown in FIG. Polarizing plate 24 for the right eye in 24
r has the same polarization angle as the polarizing plate 21, and the left eye polarizing plate 24m in the polarized glasses 24 has the same polarization angle as the polarizing plate 22. ing.

Therefore, the viewer 23's right eye sees only the right-eye reproduction W projected on the picture tube 18: the polarizing plate 21→semi-transparent mirror 19→right-eye polarization/1fi2 in the polarized glasses 24-.
4'r, and to the left eye of the viewer 23,
Only the reproduced image of Toriura projected on the picture tube 20 reaches the viewer 23 through the polarizing plate 22 → semi-transparent mirror 19 → polarizing plate 24J2 for the left eye in the polarizing glasses 24, so the viewer 23 perceives a stereoscopic image. It turns out.

Next, in the display for stereoscopic image reproduction shown in FIG. 17(b), 28 is a shutter opening/closing control signal generation circuit. The right eye shutter 27r in the shutter 27 and the left eye shutter 2i in the shutter 27 are sequentially and alternately operated during sequential vertical blanking periods in the field sequential stereoscopic TV video signal supplied to the shutter 27. A shutter opening/closing control signal is generated to open and close the shutter.

Right eye shutter 27r in the shutter 2 shutter described above
For example, for a 27Ω shutter for the left eye,
Although it may be configured as a mechanical type,
It would be preferable to use a piezoelectric material (for example, PLZT) or an electric type composed of a combination of a liquid crystal and a polarizing plate.

Note that as a display for reproducing stereoscopic images, a display having a configuration other than that described above may be used.

(Effects of the Invention) As is clear from the above detailed explanation, the recorded information recording medium disk of the present invention has a predetermined number of pieces for each round from a specific radial position to that radial position. In a recorded information recording medium disk on which N (N is a natural number) fields of video signals are sequentially recorded to form one spiral record, Nll for each of the above-mentioned sequential rotations. The video signal of the field is the left eye video signal (L1,
L2゜L3. L4..., where the subscripts are sequential field numbers), and the video signal for the right eye of the simultaneous stereoscopic television video signal (R1, R2, R3, R4...). ..., where the subscripts are sequential field numbers), in which N consecutive fields of video signals are sequentially and alternately arranged, and the recording traces are arranged sequentially across a certain radius set on the disk. However, depending on the field number of the video signal recorded in those recording traces, Li4Ri→L(i+N)→R(i

... (where i is the numerical value of the field number recorded in the recording trace that first crosses a certain radius set on the disc), the recorded information recording medium disc Since all of the video signals for the left eye of the simultaneous stereoscopic television video signal and the video signal for the right eye of the simultaneous stereoscopic television video signal are recorded, the recorded information It is possible to reproduce a three-dimensional image by simultaneously reproducing a three-dimensional TV image signal from a recording medium disc, or to reproduce a left-eye video signal and a right-eye video signal from a recorded information recording medium disc in a field sequential manner. Of course, it is possible to reproduce a stereoscopic image by reproducing the signal, and it is also possible to reproduce the simultaneous stereoscopic television video signal and the left eye video signal on the recorded information recording medium disk. A recording trace in which a video signal with field number m N (however, 9m is a natural number) is recorded in one predetermined recording trace of the right eye video signal of the stereoscopic television video signal of A control command signal is recorded in advance to displace the reproducing element from near the end of 1 to near the start of the recording trace where the video signal with the field number (mN+1...where m is a natural number) is recorded. Therefore, when the information recording medium disk is played back by a conventional video disc playback machine, only the video signal for the predetermined one of the left and right eyes can be automatically played back. In addition, when the reproducing element starts following the wrong recording trace in the case of front-loading,
- After the field interval has elapsed, the control command signal for displacing the reproduction element is recorded in advance at a predetermined position on the disc so that it can trace the correct recording trace, so that the reproduction of the plane image is performed well. Furthermore, the recording mode of audio signals is determined so that the state of audio signal reproduction does not deteriorate even if there is a problem with the displacement of the reproduction element that occurs when reproducing a flat image. Even if there is a shift in the displacement position of the reproduction element, or even if the reproduction element fails to read the displacement control command signal, it is possible to prevent the audio reproduction condition from deteriorating, and the recording of the present invention According to the information recording medium disc, it is possible to reproduce flat images and audio signals well even with a normal video disc player for playing back two-dimensional images. TV
It is also possible to satisfactorily realize the reproduction of stereoscopic reproduction images using video signals and the reproduction of stereoscopic reproduction images using field-sequential stereoscopic TV multiplied signals.
