2. the generation of shutter control signal CTL and transmission/reception
It follows that with reference to Fig. 8 to 13, described in detail below by signal processing 20 and shutter
Control the generation of the shutter control signal CTL of part 15 and by shutter control section 15 and fast peephole
The send/receive operation of the shutter control signal CTL of mirror device 60.
2-1. produces the operation of synchronous control signal Sync by signal processing 20
First, the imaging signal processing circuit 23 in signal processing 20 is (left based on such as picture signal
Eye pattern image signal and eye image signal) information or conversion timing, from user through remotely controlling
The instructions of signal RS etc. produce synchronous control signal Sync.
Fig. 8 illustrates the synchronous control signal Sync produced in this way and at above-mentioned shutter control signal CTL
In sending mode etc. between the example of relation.
As shown in part (A) in Fig. 8, synchronous control signal Sync is the letter represented by binary logic
Number.More specifically, in synchronous control signal Sync, circulate period (such as, about 100ms at one
To 4ms) the first half in, it is provided that wherein logic level is the H-period TH of " H (high) ", and
In the later half of this circulation period, it is provided that wherein logic level is the L-period TL of " L (low) ".
, as described later, substantially, the dutycycle (TH/Tsync) (%) of synchronous control signal Sync
Allow to have scope from 0% to 100% arbitrary value (the example shown in the part (A) of Fig. 8,
Such as, this dutycycle is about 48%).It addition, the dutycycle of synchronous control signal Sync (TH/Tsync)
Substantially definition represents each relative Period Length of opening of left eye shutter 6L and right eye shutter 6R and (opens
Open Period Length) unlatching dutycycle Duty (%).
It addition, such as, as shown in part (B) in fig. 8, rely on accounting for of synchronous control signal Sync
Empty amplitude (the unlatching duty of above-mentioned left eye shutter 6L and right eye shutter 6R than (TH/Tsync) (%)
Amplitude than Duty (%)) determine the sending mode etc. in shutter control signal CTL.In other words,
Multiple sending modes correspond to the pass and divide the scope (synchronous control signal opening dutycycle Duty (%)
The scope of the dutycycle (TH/Tsync) (%) of Sync) the duty cycle portion Δ Duty1 to Δ Duty3 of cutting.
More specifically, in this case, when the dutycycle (TH/Tsync) of synchronous control signal Sync
When being in from 5% to the scope (duty cycle portion Δ Duty1) less than 44%, sending mode is conditioned
For sending mode A (5%≤Duty ＜ 44%), this will be described later on.It addition, as synchronous control signal Sync
Dutycycle (TH/Tsync) be in from 45% to 55% scope (duty cycle portion Δ Duty2) including two ends
Time middle, sending mode is adjusted to sending mode B (Duty=50%), and this will be described later on.When synchronizing control
The dutycycle (TH/Tsync) of signal Sync processed is in the scope (duty cycle portion more than 56% to 95%
Δ Duty3) in time, sending mode is adjusted to sending mode C (56% ＜ Duty≤95%), and this will retouch after a while
State.In other words, in sending mode A and C, the dutycycle (TH/Tsync) of synchronous control signal Sync
Value equal to the value opening dutycycle Duty (open dutycycle Duty be variable value).On the other hand,
In sending mode B, regardless of the value of the dutycycle (TH/Tsync) of synchronous control signal Sync, open
The value of dutycycle Duty is fixed value (50%).
When the dutycycle (TH/Tsync) of synchronous control signal Sync is less than 5% or is more than 95%, should
Mode tuning is the pattern wherein performing time-out/terminal procedure, and this will be described later on.It addition, when synchronizing control
The dutycycle (TH/Tsync) of signal Sync processed is in from 44% to less than the scope of 45%, or is in
Time in scope more than 55% to 56%, this mode tuning is the pattern wherein performing Mixed Zone process,
This will be described later on.
Information based on such as picture signal or conversion timing, through the remote control signal RS from user
Instruction etc., by imaging signal processing circuit 23, accounting for of synchronous control signal Sync is set in this way
Empty than (TH/Tsync) to produce synchronous control signal Sync.
2-2. produces and sends the operation of shutter control signal CTL by shutter control section 15
It follows that shutter control section 15 produces based on the synchronous control signal Sync produced in this way
Command set CS, this command set CS are by combining from above-mentioned multiple shutter control command in a predetermined sequence
The shutter control command CMD of the one or more kinds (here, two kinds) selected in CMD comes
Configuration.Then, repeat the command set CS of generation to be sent to shutter eyeglass device 60 to perform to send soon
The operation of gate control signal CTL.
Specifically, the shutter control signal in shutter control section 15 produces part 151 based on Synchronization Control
Signal Sync produces shutter control signal CTL, to provide shutter control signal CTL to transmitting portion 153.
More specifically, first, shutter control signal produces part 151 and relies on the duty of synchronous control signal Sync
Select a sending mode (or in certain situation from multiple sending modes than the value of (TH/Tsync)
One of lower selection other procedure schemas above-mentioned).In other words, such as, as shown in part (B) in Fig. 8
, when the dutycycle (TH/Tsync) of synchronous control signal Sync is in from 5% to the model less than 44%
When enclosing middle, select sending mode A (5%≤dutycycle ＜ 44%).Equally, when synchronous control signal Sync's
When dutycycle (TH/Tsync) is in the scope including two ends from 45% to 55%, select sending mode
B (dutycycle=50%).When the dutycycle (TH/Tsync) of synchronous control signal Sync is in more than 56%
Time in the scope of 95%, select sending mode C (56% ＜ dutycycle≤95%).
It follows that shutter control signal produces part 151 keeps part 152 by using in bit pattern
The shutter control command CMD of multiple kinds of middle holding, produces what the sending mode included for selecting provided
The shutter control signal CTL of command set CS, will describe with reference to Figure 10 to 13 after a while.Now, shutter
Control signal produces the bit pattern (row of shutter control command CMD of part 151 setting command collection CS
Row sequence) so that represent the bit pattern in the bit pattern of whole command set and shutter eyeglass device 60
Keeping the bit pattern kept in part 63 identical, this will be described later on.Then, produce in this way
Shutter control signal CTL including command set CS is sent to shutter eyeglass device 60 from transmitting portion 153.
Fig. 9 explanation is according to the duty of the synchronous control signal Sync in shutter control signal generation part 151
The ratio state transition diagram of example of mode selecting operation of the value of (TH/Tsync), and corresponding to Fig. 8
Operation shown in middle part (B).
First, (when the power supply of display 10 turns on), shutter control signal produces part 151 and performs same
The initial detection process (step S1 of Fig. 9) of step control signal Sync.More specifically, shutter control letter
Number producing part 151 determines frequency fsync and the dutycycle (TH/Tsync) of synchronous control signal Sync
Value whether be in for the steady statue (normal condition when a stereoscopic image is displayed) that is described later on of execution
In transmission operation (or Mixed Zone process) predetermined scope in (sending mode A to C).
More specifically, during frequency fsync is in from 10Hz to 250Hz the scope including two ends wherein,
And the value of dutycycle (TH/Tsync) is when being in 5% to 95% scope including two ends, this operation turns
To Sync dutycycle (TH/Tsync) detection process (step S2) subsequently.On the other hand, frequency is worked as
When wherein one or two of the value of fsync and dutycycle (TH/Tsync) is outside this scope, initial detecting
Process is continued until that both values reach this scope.
It follows that shutter control signal produces part 151 performs the dutycycle of synchronous control signal Sync
(TH/Tsync) detection process (step S2).Then, as it has been described above, according to dutycycle (TH/Tsync)
Value select from multiple sending mode A to C a sending mode with perform send operation.In other words,
Select sending mode A process (S3), sending mode B process (S4) or sending mode C process (S5)
To perform to send operation.Alternatively, depend on that the value of dutycycle (TH/Tsync) performs other process moulds
One of formula (Mixed Zone process (step S6) and time-out/terminal procedure (step S7)).
More specifically, when the dutycycle (TH/Tsync) of synchronous control signal Sync is in from 5% to little
Time in the scope of 44%, select sending mode A process (5%≤dutycycle ＜ 44%).It addition, when synchronizing
When the dutycycle (TH/Tsync) of control signal Sync is in the scope including two ends from 45% to 55%,
Select sending mode B process (dutycycle=50%).Dutycycle as synchronous control signal Sync
(TH/Tsync), when being in the scope more than 56% to 95%, sending mode C process (56% ＜ is selected
Dutycycle≤95%).On the other hand, it is less than when the dutycycle (TH/Tsync) of synchronous control signal Sync
5% or more than 95% time, select time-out/terminal procedure.Additionally.Duty as synchronous control signal Sync
It is in from 44% to less than the scope of 45% or be in the model more than 55% to 56% than (TH/Tsync)
When enclosing middle, select Mixed Zone process.
Operation in steady statue
Transmission operation (sending mode A to C) being described more fully below in steady statue.
Figure 10 illustrates the sequential chart of the operation example in steady statue.Figure 10 (and after a while will describe
Figure 12 and 13) in, partly (A) and (D) instruction operation during sending mode A, portion
Divide (B) and (E) instruction operation during sending mode B, and part (C) and (F) indicates
Operation during sending mode C.It addition, part (A) to (C) suitable by from upper in the drawings
Sequence instruction left eye shutter control signal CTLL based on shutter control signal CTL generation and right eye shutter control
The timing waveform (impulse waveform) of signal CTLR processed, the shutter included at shutter control signal CTL
The description (arriving " F " corresponding to " A " in Fig. 6 B) of control command CMD and synchronous control signal Sync
Timing waveform (impulse waveform).On the other hand, partly (D) to (F) indicates configuration order collection CS
Each shutter control command CMD, the description (" A " arrives " F ") of shutter control command CMD and
The putting in order along time shaft of the logical value of each bit (CB4 to CB1) of Command field bit CB.Can
It is, in order to simplify the event of accompanying drawing, in " E " and " F " of the shutter control command, " L-in Fig. 6 B
Unlatching/R-close " and " R-unlatching/L-Guan Bi " respectively by " L-O/R-C " and " R-O/L-C " expression.
Equally, as the logical value of bit CB4 to the CB1 of Command field bit CB, " 1 " is only shown, and does not shows
Go out " 0 ".As arrived shown in (C) in part (A), in this case, when left eye shutter control signal
When CTLL is in " H " level, left eye shutter 6L is adjusted to opening, and when left eye shutter control
When signal CTLL is in " L " level, left eye shutter 6L is adjusted to closure state.Equally, right eye is worked as
When shutter control signal CTLR is in " H " level, right eye shutter 6R is adjusted to opening, and works as
When right eye shutter control signal CTLR is in " L " level, right eye shutter 6R is adjusted to closure state.
First, during the sending mode A shown in the part (A) of Figure 10 and (D), open
Dutycycle Duty is in scope 5%≤unlatching dutycycle Duty ＜ 44%, pretends as shutter control command
" B " (the L-unlatching), " A " (L-Guan Bi), " D " (R-unlatching) and " C " (R-Guan Bi) of CMD
Repeat in the order.Therefore, as in Figure 10 part (D) and Figure 11 A shown in, command set now
CS includes four shutter control command CMD according to " B ", " A ", " D " and " C " order.So
After, represent that the bit pattern of whole command set CS is " 0100100000010010 " as shown in Figure 11 A.
It addition, during sending mode B shown in the part (B) of Figure 10 and (E), due to
Opening dutycycle Duty is 50%, as shown in part (B) in Figure 10, performs a left side at identical timing
Be sharp-eyed a 6L and right eye shutter 6R operation conversion.Therefore, during sending mode B, use multiple
Close order, and as " E " (L-unlatching/R-terminates) and " F " (R-of shutter control command CMD
Unlatching/L-closes) repeat in this order.Therefore, as in Figure 10 part (E) and Figure 11 B shown in, this
Time command set CS by according to " E " and " F " sequence alternate arrangement two shutter control command CMD
(two interdictum duplexs) configures.Then, the bit pattern representing whole command set CS is such as Figure 11 B
Shown " 10100101 ".
Further, during sending mode C shown in the part (C) of Figure 10 and (F), open
Dutycycle Duty is in scope: 56% ＜ opens dutycycle Duty≤95%, pretends as shutter control command
" B " (the L-unlatching), " C " (R-Guan Bi), " D " (R-unlatching) and " A " (L-Guan Bi) of CMD
Repeat in this order.Therefore, as in Figure 10 part (F) and Figure 11 C shown in, command set CS now
By joining according to the order of " B ", " C ", " D " and " A " four shutter control command CMD of arrangement
Put.Then, the bit pattern representing whole command set CS is as shown in Figure 11 C
“0100001000011000”。
In an embodiment, each command set CS by different bit pattern configurations is produced for multiple transmissions
Pattern (in this case, three sending mode A to C), and this command set CS is included in soon
In gate control signal CTL and be transmitted repeatedly.
Operation during beginning
It follows that not predetermined beginning shown in the part (B) of Fig. 8 and Fig. 9 explained below
During operation.Beginning process is in the power supply conducting of display 10 or aobvious from two dimension at display 10
Show the process that pattern performed when three-dimensional (stereo-picture) display pattern changes its display pattern.
More specifically, such as, as shown in part (A) to (C) in Figure 12, during starting
Each sending mode process (sending mode A process, sending mode B process, sending mode C process)
In transmission the operation substantially and in Fig. 10 steady statue shown in part (A) to (C) in
Send operation identical.In other words, the bit pattern in the command set CS of each sending mode and
Bit pattern in steady statue shown in Figure 11 A to 11C is the same., such as portion in fig. 12
Divide shown in (A) to (C), before changing to three-dimensional display mode (in two dimensional mode),
Left eye shutter 6L and right eye shutter 6R two is in opening.
During starting, the bit pattern in shutter eyeglass device 60 determines command set CS is repeated
Receiving repeatedly, shutter eyeglass device 60 identifies the instruction changing display pattern, and starts at three dimensional display
Operation in pattern.
Operation during Mixed Zone
It follows that the operation (step S6 of Fig. 9) during Mixed Zone explained below.Mixed zone
Territory process is the process not used, but if operates the duty according to synchronous control signal Sync
Change to this process than the value of (TH/Tsync), then perform this operation as follows.In Mixed Zone process
In, the bit pattern of command set CS (sending mode A process, is not sent out from previous sending mode process
Send Mode B process or sending mode C process) change, and according only to opening the value of dutycycle Duty
The transmission timing of shutter control command CMD is set.
Operation in time-out/terminal procedure
It follows that the operation being described more fully below in time-out/terminal procedure (step S7 of Fig. 9).Temporarily
Stop/terminal procedure is such as to change to two dimensional mode from three-dimensional (three-dimensional) display pattern at display 10
The process performed when becoming its display pattern.
As shown in the part (B) of Fig. 8 and Fig. 9, except the dutycycle of synchronous control signal Sync
(TH/Tsync) outside being less than 5% or being more than 95%, when the H-period in synchronous control signal Sync
TH in certain period (such as, 100ms) or is not then performed this time-out/end above by sequence detection
Process.In other words, shutter control signal produces part 151 in Sync dutycycle (TH/Tsync) inspection
During survey, value or the logic level of dutycycle based on synchronous control signal Sync (TH/Tsync) are true
Surely ceasing and desisting order and collect generation and the transmission of CSf, this will be described later on (step S2 of Fig. 9).Stop life
Order collection CSf is configured by some of the shutter control command CMD of the multiple kinds of use, and is to use
Drive in the opened/closed stopping left eye shutter 6L and right eye shutter 6R and make left eye shutter 6L and right eye
Shutter 6R is in the command set of opening.
Specifically, such as, as shown in part (A) to (C) in Figure 13, shutter control signal produces
Part 151 performs to cease and desist order and collects generation/transmission operation of CSf.In other words, rely on previous
Sending mode process (sending mode A process, sending mode B process or sending mode C process) is opened
While opening the setting sending timing of value maintenance shutter control command CMD of dutycycle Duty, produce
The public collection CSf that ceases and desist order for each sending mode.
More specifically, at this moment, as " D " (the R-unlatching) and " D " of shutter control command CMD
(R-unlatching) the most repeatedly (in this case, ten times).Therefore, as in the middle part of Figure 13
Divide shown in (A) to (F), in the collection CSf that ceases and desist order, two shutter control command of identical type
The combination of CMD, that is, " D " and " D " is repeated 10 times (that is, " D " is repeated 20 times).So
After, represent that the bit pattern of whole command set CS is the 10 of " 00010001 " as shown in fig. 11C
Secondary repetition.When two command in combination of identical type are a set, this set sends repeatedly (10 times),
Allow to strengthen the opposing to external noise；Accordingly it is possible to prevent fault.More specifically, greatly reduce this
The probability of sample: while " B ", " A ", " D " and " C " sends in steady statue, due to
External noise, have different circulation " B ", " A " and " C " loss and only " D " be repeatedly transmitted.
Therefore, may be implemented in sending side and the highly reliable communication received between side.In this case, logical
Cross the collection of ceasing and desisting order repeating repeatedly to configure as " D " (the R-unlatching) of shutter control command CMD
CSf is to describe as example；, can be by repeating the shutter control command CMD's of multiple kind
Any other repeatedly configures the collection CSf that ceases and desist order.
Therefore, in an embodiment, shutter control section 15 produces order based on synchronous control signal Sync
Collection CS (or command set Csf, it is equally applicable to hereafter), this command set CS is by a predetermined sequence
The shutter control of one or more kinds that combination selects from the shutter control command CMD of multiple kinds
Order CMD configures.Then, by repeating to send the command set CS of generation to shutter eyeglass device 60
Perform the transmission operation of shutter control signal CTL.Additionally, now, the bit of setting command collection CS
Pattern so that the bit pattern representing whole command set CS and the ratio kept in shutter eyeglass device 60
Special type formula is identical, and this will be described later on.
2-3. is operated by the reception of the shutter control signal CTL of shutter eyeglass device 60
It follows that in shutter eyeglass device 60, receiving portion 61 receives and includes that command set CS's is fast
Gate control signal CTL, this command set CS are to repeat to send from shutter control section 15 in this way.
Then, it is determined that the control routine of the shutter control signal CTL of circuit 62 translation reception (represents whole life
The bit pattern of order collection CS) to determine that the opened/closed of left eye shutter 6L and right eye shutter 6R instructs.
More specifically, determine circuit 62 perform receive representative whole command set CS bit pattern and than
Special type formula keeps the pattern match between the bit pattern in the corresponding sending mode kept in part 63.
More specifically, in this embodiment, bit pattern keeps part 63 keep and represent whole command set
The bit pattern that the bit pattern of CS is identical, this command set CS expection (hypothesis) is by receiving portion 61
Receive.In other words, bit pattern keeps part 63 to keep in advance and in shutter control section 15
Bit pattern keeps the identical bit pattern of bit pattern of part 152.More specifically, from display
10 repeat, in the command set CS sent, to represent bit pattern and the shutter eyeglass device of whole command set CS
The bit pattern kept in 60 is identical.Therefore, when from sending side (display 10) to receiving side (shutter
Glasses device 60) send when including the shutter control signal CTL of command set CS, shutter eyeglass device 60
Easily determine whether this command set CS includes external noise.
Determine that circuit 62 performs the pattern match between bit pattern as follows.First, conversion is worked as
During sending mode etc., determine circuit 62 it confirm successively multiple command set CS bit pattern and than
When the bit pattern of holding is identical in special type formula holding part 63, determines and include that normal command collection CS's is fast
Gate control signal CTL is received.On the other hand, the ratio special type that the command set CS received wherein includes
In the case of formula is different from the bit pattern kept in bit pattern keeps part 63, determine circuit 62
Determine that the shutter control signal CTL including command set CS includes external noise.Note, in conversion every time
After sending mode, determine that circuit 62 performs in the bit pattern of each command set CS with in bit pattern
Keep the pattern match between the bit pattern kept in part 63.
Alternately, such as, determine that the command set CS received can be performed by circuit 62 as follows
Determine.More than two ratio in receiving by Command field bit CB (CB4 to CB1) of four bit configuration
In the case of " 1 " of special (3 bits or more), the bit pattern of Command field bit CB is different from
Any one shutter control command CMD shown in Fig. 6 B；Accordingly, it is determined that circuit 62 determines fast gate
Signal CTL processed includes external noise.Additionally, receive any other bit pattern wherein and do not received
In the case of acting as the beginning bit SB of lead code, determine that circuit 62 determines shutter control signal CTL
Including external noise.In these cases, such as, the command set CS of reception is cancelled, and according to
Receive in the command set CS execution shutter eyeglass device 60 received before the command set CS cancelled following closely
The opened/closed operation (oneself performs) of shutter.It addition, wherein from the shutter control of display 10
In the case of the transmission of signal CTL is interrupted, such as, the unlatching of shutter in shutter eyeglass device 60/close
Closing operation oneself performs to reach certain period (such as, several seconds), and hereafter, shutter eyeglass device 60 is adjusted
Joint is to holding state.
It addition, in the command set CS (except the collection CSf that ceases and desist order) of embodiment, such as, such as Figure 10
To shown in 13, the position of the bit of instruction " 1 " (instruction effective status) is inevitably by from high-order ratio
Special to low step bit or the order from low step bit to higher order bits, from a shutter control command CMD
Change to adjacent shutter control command CMD.Alternately, in the case of two interdictum duplexs, phase
Adjacent bit is changed.Therefore, in command set CS, represent the position of bit of " 1 " be set to
Predetermined rule changes into adjacent shutter control command CMD from a shutter control command CMD.More
Specifically, in this case, in adjacent shutter control command CMD, " 1 " is not positioned over phase
Same bit position.Therefore, when sending and receive the command set CS of thus analogy special type formula configuration,
Obtain and be prone to determine the effect that the bit not disposed by rule is noise.
It addition, such as, as shown in figure 13, the collection CSf that ceases and desist order in embodiment has such bit
Pattern, the shutter control command CMD of one of them and identical type is substantially (fixed by different intervals
Time) repeat.Therefore, when send and receive thus analogy special type formula configuration cease and desist order collection CSf time,
Obtain the effect of fault allowing to prevent to cause in steady statue due to the loss of shutter control command CMD
Really.
