Embodiment
For effect that the expensive auditor of profit understands technical characteristic of the present invention, content and advantage and can reach, hereby the present invention is coordinated accompanying drawing, and be described in detail as follows with the expression-form of embodiment, and it is wherein used graphic, its purport is only the use of signal and aid illustration book, may not be actual proportions after the invention process and precisely configure, therefore should with regard to appended graphic ratio and configuration relation is not understood, the interest field limited the invention in actual enforcement, conjunction is first chatted bright.
Refer to Fig. 3, it is the calcspar of the embodiment for shutter release timing adjustment method and device of the present invention.As shown in the figure, shutter release timing adjustment method and device 1 of the present invention, is applicable to an anaglyph spectacles, and it can comprise receiving element 10, timer 11 and a processing module 12.Wherein, the better liquid crystal of arranging in pairs or groups of the shutter of this anaglyph spectacles (Liquid Crystal), is done by the mode controlling light transmittance and covers: that is, when the light transmittance relative transparent of liquid crystal, the namely general said unlatching when reality is implemented; Otherwise, when the light transmittance of liquid crystal is relatively opaque, the namely general said closedown when reality is implemented.
When anaglyph spectacles operates at the beginning, receiving element 10 can receive one first clock signal 201 sent by the signal transmitter unit 20 in an external image equipment 2; In the present embodiment, the first clock signal 201 can be the infrared synchronous signals that external image equipment 2 end sends.Processing module can be electrically connected receiving element 10 and timer 11, and it can comprise microprocessor (Micro-Processing Unit) or central processing unit (Central Processing Unit, CPU).After receiving element 10 receives the first clock signal 201, the first clock signal 201 that receiving element 10 can receive by processing module 12, be sent to timer 11, be set to identical with the cycle of the first clock signal 201 in the cycle of the second clock signal 111 in timer 11.So, processing module 12 can control timer 11 to switch the shutter of anaglyph spectacles.
Accept above-mentioned, the demand implemented in response to reality, receiving element 10 every a Preset Time, can receive the first clock signal 201 sent by the signal transmitter unit 20 in external image equipment 2.And processing module 12 by the cycle of cycle synchronisation to the first clock signal 201 of the second clock signal 111 of timer 11, and can control timer 11 to switch the shutter of anaglyph spectacles.But, if when its communication channel is subject to hindering, that is, when receiving element 10 does not receive the first clock signal 201 sent by the signal transmitter unit 20 in external image equipment 2, now, processing module 12 according to the cycle of the second clock signal 111 of timer 11, can carry out the switch of anaglyph spectacles shutter.
Then, when receiving element 10 receives the first clock signal 201 sent by external image equipment 2 again, the cycle of the second clock signal 111 in the cycle of this first clock signal 201 and timer 11 can compare by processing module 12, produces a side-play amount with correspondence; Further, processing module 12 can be no more than the size of a preset value, according to this side-play amount step by step by the cycle of cycle synchronisation to the first clock signal 201 of the second clock signal 111.
Incidentally, the first clock signal 201 and the second clock signal 111 all contain the left shutter release sequential of anaglyph spectacles and right shutter release sequential.And should understand person with usual knowledge in their respective areas of the present invention, those skilled in the art when can become an integrated module in conjunction with above-mentioned functional module arbitrarily, or are split into each functional details unit, and end is seen convenience in design and determines.
Refer to Fig. 4 further, it is the flow chart of an embodiment of method of adjustment for shutter release sequential of the present invention.As shown in the figure, the method for adjustment of shutter release sequential can use the switching sequence of optimization 3D anaglyph spectacles shutter.The method of adjustment of this shutter release time comprises the following step.Step 41: receive the synchronizing signal that image documentation equipment sends.When reality is implemented, can be roughly the same noted earlier, the first clock signal sent by the signal transmitter unit in external image equipment is received by receiving element.Step 42: the cycle of clock signal in timer is set to identical with the cycle of synchronizing signal.Step 43: utilize timer to switch anaglyph spectacles shutter.Again, step 44: carry out the judgement whether synchronizing signal interrupts: if not, then perform step 43; If so, then step 45 is performed.In step 45: utilize timer to switch anaglyph spectacles shutter.
Then, step 46: confirm whether synchronizing signal is recovered, if not, then performs step 45; If so, then step 47 is performed.In step 47: receive the synchronizing signal that image documentation equipment sends.Step 48: the side-play amount comparing the cycle of clock signal in cycle of synchronizing signal and timer.
Explain above-mentioned several step, on reality is implemented, the interruption of synchronizing signal is likely that its communication channel is temporarily hindered, and makes receiving element temporarily cannot receive the first clock signal sent by external image equipment; Or with regard to power saving aspect, anaglyph spectacles just may can open every a Preset Time reception that receiving element carries out clock signal, such as, every 500 milliseconds (ms), receiving element just can carry out the reception of clock signal.When receiving element receives the synchronizing signal that external image equipment sends again, the now cycle of the clock signal difference (please consulting Fig. 2 again) that may will go up for some time with synchronizing signal in timer.
Now, the cycle of clock signal in the cycle of synchronizing signal and timer can compare by processing module, produces a side-play amount with correspondence.Then, in step 49: judge whether side-play amount is greater than admissible maximum adjusted value, if so, step 50 is performed.In step 50: in former timer, the initial time of clock signal deducts admissible maximum adjusted value, be the initial time of the clock signal after upgrading in timer.On reality is implemented, admissible maximum adjusted value can be set as 100 microseconds (μ s) or 50 microseconds, and end is seen actual demand and determines; If side-play amount is 300 microseconds, the initial time forward/backward then representing clock signal in former timer offset by 300 microseconds, and the initial time of now new in timer clock signal can forward/backward correct 100 microseconds or 50 microsecond ends and sees demand in setting accordingly.After correction, then resumes step 47, iteration so repeatedly, until the clock signal in timer is synchronous with the synchronizing signal that receiving element receives.In addition, if side-play amount is less than or equal to admissible maximum adjusted value, then step 51 is performed.Step 51: in former timer, the initial time of clock signal deducts side-play amount, is the initial time of the clock signal after upgrading in timer.
It is worth mentioning that, should understand person with usual knowledge in their respective areas of the present invention, the enforcement aspect that aforementioned receiving element carries out the time interval of clock signal reception, admissible maximum adjusted value and side-play amount etc. is only for example and not limitation, any spirit and category not departing from this shutter release timing adjusting method, spirit of the present invention all should be contained in, chat bright in advance at this.
Refer to Fig. 5, it is the shutter sequential adjustment schematic diagram for one embodiment of the invention.As shown in the figure, the shutter release sequential SST after it denotes left image LI, right image RI, left shutter opening LO, right shutter opening RO, correct shutter release sequential CST, skew, first time correct shutter release sequential 1ST, second-order correction shutter release sequential 2ST, third time corrects environment light source change G ' between shutter release sequential 3ST, environment light source brightness EL, correct left shutter opening time point A, the left shutter opening time point B of skew, left shutter opening time point B1, B2, B3 and B of successively revising, B1 modified twice.
When the left shutter opening time point B offset and correct left shutter opening time point A lead time are too far away, processing module can adopt the mode progressively adjusted, such as each with 50 microseconds or 100 microseconds for spacing adjusts, in the present embodiment, the left shutter opening time point B such as offset and correct left shutter opening time point A lead time 130 microseconds, processing module can 50 microseconds be that a unit adjusts, by B to B1 again by B1 to B2, finally again 30 remaining microseconds are adjusted to B3 by B2.That is, by B1, B2, B3 ... approach to A point gradually.And the time point changed because of each shutter reduces, therefore the change of environment light source also can and then be reduced; So, user can not perceive the flicker of shutter.
In sum, shutter release timing adjustment method and device proposed by the invention and method of adjustment thereof can in response to the changes of environment light source, with the switching sequence of optimization 3D anaglyph spectacles shutter, namely progressively adjust the sequential of shutter release, when switching to avoid shutter, cause flicker.Allow user discover flicker less than shutter, and then promote the image rating quality that user uses active stereo glasses.
The foregoing is only illustrative, but not be restricted person.Anyly do not depart from spirit of the present invention and category, and to its equivalent modifications of carrying out or change, all should be contained in claim.
