In addition, in this execution mode, the reception mean value at interval that will obtain for each signal is as the cycle of the 1st to the 6th signal, but the utility model is not limited thereto.As other method, also can adopt median from a plurality of the reception the value at interval of obtaining, also can be used as other method and use the mean value of removing the part beyond minimum value, the maximum.That is, if based on actual reception to the reception of signal calculate at interval at interval as the reception of representative, can be any computational methods.
In addition, order receives interval calculation portion 312 may not need the cycle of above-mentioned each signal is fixed as the once cycle of decision.Also can when receiving order, upgrade should the cycle.At this moment, when making under the situation of display cycle variation etc. by each scene in the holographic display device side, stereopsis is watched the variation that can follow command cycle with glasses 150.
< order receives the grouping and the judgement of signal >
Order receives interval calculation portion 312 and carries out packet transaction based on the cycle that the calculated signals according to each reception goes out.The method of dividing into groups has multiple.
For example, as make in advance about under the some consistent situation in a plurality of cycles of two optical filtering portion cycle of carrying out on-off action and decision, order reception interval calculation portion 312 is according to this cycle that is predetermined, the grouping of the signal that receives.During image about stereopsis shows with 120Hz, as merely calculating, the demonstration time of each frame is:
1000(ms)/120(Hz)＝8.3(ms/frame)。
Be made as order, the order of closing left eye (should be right eye) optical filtering portion 309 of opening left eye (should be right eye) optical filtering portion 309 when order receives signal that interval calculation portion 312 should receive, open the order of right eye (should be left eye) optical filtering portion 310, when closing the order of right eye (should be left eye) optical filtering portion 310, the action of carrying out based on this this order is shown in Fig. 4 (c).Order reception interval calculation portion 312 can infer each signal (order) based on the above-mentioned cycle and show that with above-mentioned frame the reception of about twice of time is received at interval.
In view of the above, order receive interval calculation portion 312 will with the reception about 16.6 (ms) of the twice of 8.3 (ms) at interval received signal be estimated as effective order.Signal in addition is regarded as invalid signals (interference signal).According to the average period of Fig. 5, it is effective order with the 1st to the 4th signal packets that order receives interval calculation portion 312, and the 5th signal, the 6th signal are judged as interference signal.That is, whether can according to the cycle of the signal that receive be about the integral multiple in the cycle that be predetermined judge whether be effective order in order if receiving interval calculation portion 312.In addition, here " about " refer to the scope of error of the several percentage degree in front and back of theoretic command cycle, be the situation that has the signal period.
In addition, as other method, order receives interval calculation portion 312 also can only carry out the grouping of effective order based on the cycle of each signal that calculates.Order receives the cycle of interval calculation portion 312 based on each signal shown in Figure 5, and the cycle that whether comprises other signal in the scope according to 97% to 103% (being the scope of its value front and back 3% amplitude) of the periodic quantity of each signal divides into groups.At this moment, as shown in Figure 6, for the 1st to the 4th signal, all signals all are comprised in the scope of 3% amplitude, and for the 5th, the 6th signal, they but are not comprised in the scope of 3% amplitude.In view of the above, order reception interval calculation portion 312 also can only divide into groups effective order.In addition, in this execution mode, be example with the amplitude of front and back 3%, but the utility model value of being not limited thereto.
Fig. 7 shows the figure that order receives the result that interval calculation portion 312 divides into groups.In Fig. 7, put down in writing the signal that receives respectively on polygonal each summit, receive the signal that interval calculation portion 312 is judged as effective order for order, interconnect with solid line.Thus, can only discern effective signal clearly.
<based on the optical filtering portion control of effective order >
Effective order extraction portion 313 only extracts from the signal from acceptance division 301, enlarging section 302 by order and receives the signal that interval calculation portion 312 regards as effective order.The input signal that effective order extraction portion 313 is ignored in addition.Effective order extraction portion 313 controls the on-off action (Fig. 4 (c)) of left eye (should be right eye) optical filtering portion 309, right eye (should be left eye) optical filtering portion 310 according to the control content of effective order through optical filtering control part 314, optical filtering drive division 308.
According to the above, in this execution mode, from the signal that receives, automatically only extract effectively order, and remove interference signal etc., thereby can suppress the influence that interference signal causes.Its result, stereopsis is watched with glasses 150 can reduce the control disorder that interference signal causes.
Fig. 8 representes another example of the utility model, is the time of reception and the figure in cycle separately that expression receives signal.Fig. 8 (a) is the figure that the expression stereopsis is watched the signal that receives with glasses 150 on time shaft.Fig. 8 (b) calculates the figure that stereopsis is watched the cycle of the various command that receives with glasses 150.Illustrated among Fig. 8 (a) to receive and be used to control stereopsis and watch 4 kinds of orders, but (in Fig. 8 (a), represented to number " 1 " to " 5 " by the numbering " 1 " of zone circle and subscript at the 1st signal with glasses 150.) in, sneaked into interference signal and reception order aperiodically.Below, in Fig. 8 (a), use corresponding with the numbering of the zone circle of representing the 1st signal " 1 1" to " 1 5" symbol, the command string of the 1st signal is described.In this example shown in Figure 8, explain from the 1st signal (" 1 1" to " 1 5") command string in extract the method for effective order.
Order receives interval calculation portion 312 and is receiving the 1st signal (" 1 shown in Fig. 8 (a) 1" to " 1 5") time, the reception that calculates each signal opportunity based on the reception of these signals is at interval.In the example of Fig. 8, order receives interval calculation portion 312 and obtains from receiving interval T 1-12To T 1-45Till totally 10 receive at interval.
Order receives interval calculation portion 312 and judges that the order of obtaining receives at interval the interval of time of about twice of the demonstration time that whether is the frame pre-estimated.That is, during image about for example stereopsis shows with 120Hz, the demonstration time of each frame of the left and right sides is:
1000(ms)/120(Hz)＝8.3(ms/frame)，
Order receives interval calculation portion 312 and judges whether the order of obtaining receives consistent with the promptly about 16.6ms of its twice at interval.
Fig. 9 representes its result, T 1-12, T 1-14, T 1-24Order mean that at interval the integral multiple with the frame period pre-estimated receives, can infer in 5 the 1st signals of inspection " 1 1", " 1 2", " 1 4" these 3 signals are correct control signal.
In view of the above, order receive interval calculation portion 312 will with the reception about 16.6 (ms) of the twice of 8.3 (ms) at interval received signal be estimated as effective order.And signal in addition is regarded as invalid signals (interference signal).According to the result of Fig. 9, order receives interval calculation portion 312 with " 1 1", " 1 2", " 1 4" be grouped into effective order, with " 1 3", " 1 5" be judged as invalid signals (interference signal).That is, whether order reception interval calculation portion 312 can judge about the integral multiple in the cycle that is predetermined whether signal is effective according to the cycle of the signal that receives.
According to the above, in this execution mode, from the signal that receives, automatically only extract effective signal, and remove interference signal etc., thereby can suppress the influence that interference signal causes.Its result, stereopsis is watched with glasses 150 can reduce the control disorder that interference signal causes.
In addition; The operational part of explaining in this execution mode 304 (input switching part 311, order receive interval calculation portion 312, effective order extraction portion 313, optical filtering control part 314) both can be used as the software program of CPU204 shown in Figure 2 and had realized, also can be used as hardware configuration such as FPGA and realized.
Above-mentioned execution mode mainly possesses following structure.
The related stereopsis of above-mentioned execution mode is watched and used glasses, comprising: order receives interval calculation portion, calculates the cycle of the signal that receives from the outside, and determines effective signal according to the cycle that calculates; Effective order extraction portion only extracts said effective signal from the signal that the outside receives; And the optical filtering control part, according to the order of said extraction, control to inject the spectator about two light quantity the left eye optical filtering portion and the right eye optical filtering portion that adjust.
In view of the above, during existing from the reception order of outside in, stereopsis is watched with glasses and is carried out accepting of order, therefore receives the probability step-down of interference signal, can reduce the possibility that stereopsis watches that the control with glasses gets muddled.
In said structure; Comparatively it is desirable to; Said order receives the cycle that interval calculation portion goes out the signal that receives from the outside by every kind of calculated signals, and is effective signal with the signal deciding of difference in the scope of appointment of the integral multiple in this cycle that calculates and predefined cycle.
