In addition, in this execution mode, with the reception of the signal that receives N cycle on average ordering receiving cycle as the 1st to the 4th and calculate at interval, but the utility model is not limited thereto.As other method, also can adopt median, also can use the mean value of removing the part beyond minimum value, the maximum.That is, if based on actual reception to the reception of reception signal calculate at interval at interval as the reception of representative, can be any computational methods.
Order receives the period that interval calculation portion 312 can receive each order at interval and at last according to the reception of each order that calculates, and calculates the opportunity that next receives each order.The receiving cycle of each order that order reception interval calculation portion 312 will calculate remains in the memory section 306.
Fig. 8 is the flow chart of the handling process when representing to order the receiving cycle that receives 312 each order of calculating of interval calculation portion.
(step S801)
Order receives the reception of interval calculation portion 312 initiation commands.
(step S802)
Order receives interval calculation portion 312 and judges whether the reception of the order of N receiving cycle is accomplished.If the reception of the order of N receiving cycle is not accomplished as yet, then order receives interval calculation portion 312 and causes the control return to step S801.If the reception of the order of N receiving cycle is accomplished, then order reception interval calculation portion 312 makes control transfer to step S803.
(step S803)
Order receives opportunity is calculated each order by interval calculation portion 312 according to the order reception of N the receiving cycle that receives receiving cycle.
(step S804)
Order receives interval calculation portion 312 decides the conduct representative according to the receiving cycle of each order that calculates receiving cycle separately.
Through above processing, order receives interval calculation portion 312 can obtain the receiving cycle of each order.
In addition, order receives interval calculation portion 312 may not need the cycle of above-mentioned each order is fixed as the once cycle of decision.Also can when receiving order, upgrade should the cycle.At this moment, for example also there is the result that the mean value and this order weighted average at interval at the order reception interval that last computation is gone out are calculated gained to be made as the method that new order receives the interval.Thus, 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.
< about the setting of order reception period >
Order reception period control part 313 calculates and remains on reception in the memory section 306 etc., each order at interval and control optical filtering control part 314 period that receives each last order based on received interval calculation portion 312 by order.
Stereopsis is watched with the right eye optical filtering portion 309 of glasses 150 and left eye optical filtering portion 310 and is synchronously carried out basic open and close controlling with the left and right sides image that holographic display device 100 is shown.If holographic display device 100 shown about cycle of stereopsis fix, then when so that for example 120Hz shows each image, right eye optical filtering portion 309 and left eye optical filtering portion 310 are also according to its work.
Therefore, order reception period control part 313 just can be predicted the opportunity that receives order according to the cycle of each order of ordering reception interval calculation portion 312 to be calculated in advance as long as the cycle of the order that holographic display device 100 sends is fixed.Therefore, 313 of order reception period control parts receive order during in, will import switching part 311 and be made as effectively, the signal importing operational part 304 that will import from acceptance division 301, enlarging section 302.On the contrary, for be predicted as can't receive order during, order reception period control part 313 is made as and invalidly stops from the outside signal to operational part 304 and import through import switching part 311.
Fig. 5 (b) is that expression is to the order from holographic display device shown in Fig. 5 (a), by the figure of the state of ordering reception period control part 313 control input switching parts 311.In Fig. 5 (b), the part of high (High) is represented to import switching part 311 and is set as effectively.In Fig. 5 (b), the part of low (Low) represent to import switching part 311 be set as invalid.
Order reception period control part 313 is ordered and the 4th order to the 1st, receives each cycle of ordering that interval calculation portion 312 calculates based on order, will import switching part 311 and be made as effectively (Fig. 5 (b)).Order reception period control part 313 is made as effectively than importing switching part 311 in advance in advance the opportunity that is predicted as the reception order.In the fixed time of from then on having counted, be in the D1 under the situation of the 1st order of Fig. 5 (b), will import switching part 311 and be made as effectively.In view of the above, even on transmission opportunity of sending the 1st order from holographic display device a little in advance or under the situation about delaying, as long as be in reception period D1 during in, stereopsis watches that can both receive the 1st with glasses 150 orders.Order reception period control part 313 after through reception period D1, will import switching part 311 be made as invalid.Order reception period control part 313 carries out this processing to the 1st order with cycle T 1 repeatedly.For the 4th order too, order reception period control part 313 will be imported switching part 311 in advance and be made as effectively, and D4 during effective status is kept controls with cycle T 4.
In addition, 313 pairs the 2nd orders of order reception period control part are ordered the different processing of carrying out with the 1st order, the 4th order of situation with the 3rd.At this moment, order reception period control part 313 carries out the reception of the 2nd order and the 3rd order in identical reception period D2.This depends on that reception that order receives each order that interval calculation portion 312 calculates at interval and the relation between reception period.That is, from after receiving the 2nd order till receiving the 3rd order during when being shorter than the fixed time, order reception period control part 313 control input switching parts 311 are effective all the time, during 1 in the reception of two orders of completion.
In view of the above, can prevent input switching part 311 for the situation of sending the 3rd order in during invalid from holographic display device 100 under operational part 304 import the reception Signal Fails.
And order reception period control part 313 need not to carry out all the time as stated the setting of order reception period.Only carry out above-mentioned processing under the situation about can fully predict etc. and get final product receiving from the order of holographic display device 100.
Therefore, when stereopsis is watched under the init state after starting with glasses 150 or can't fully receive the order of N receiving cycle (Fig. 6), order reception period control part 313 to make to import switching part 311 to be always effective status.
In addition, when order reception period control part 313 also can can't receive order in the order reception period of being predicted (Fig. 7), in subsequently processing etc., make input switching part 311 be always effective status.
The situation of Fig. 7 (b) is that order reception period control part 313 begins to make all the time input switching part 311 effective situation from next order reception period in the time can't receiving the situation of the 2nd and the 3rd order of being predicted at last.
And, as other method, there is the situation of Fig. 7 (c).This situation is in the time can't receiving the 2nd and the 3rd order of being predicted at last, makes input switching part 311 effective all the time, the situation till receive order next time.
According to the above, in this execution mode, through only predict receive order during inner control input switching part, thereby import order to operational part 304.On the contrary, beyond the order reception period, operational part 304 does not receive any signal.Therefore, can reduce stereopsis and watch the possibility that receives interference signal with glasses 150, it is disorderly to reduce the control that causes because of interference signal.
In addition; The operational part of explaining in this execution mode 304 (input switching part 311, order receive interval calculation portion 312, order reception period control part 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 is characterised in that with glasses and comprises: input switching part, the order input that control receives from the outside are effectively or invalid; Order receives interval calculation portion, based on the said order that receives from the outside, calculates the cycle of each order; Order reception period control part, based on the cycle of said each order, decision next receive order during, in during this period, said input switching part is set at effectively; And the optical filtering control part, the order that receives from the outside in during being based on said order reception period control part and will importing switching part and be made as effectively, 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 the acceptance of carrying out order with glasses, 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 reception period control part, for during can't receiving from the order of outside, it is invalid that said input switching part is set in decision.
