Description
Technical field
The present invention relates to 3D technical field, be related specifically to a kind of debugging apparatus and detection method of 3D synchronizing signal phase place.
Background technology
In recent years, television set industry has welcome 3D TV upsurge.Because current industry does not have corresponding standard to put into effect, corresponding measuring instrument is not had to detect and corrects the performance of 3D TV yet, cause situation market having occurred the tangled warfare of 3D television set, old-fashioned double-colored 3D, dragons and fishes jumbled together for polarisation 3D, shutter 3D and the external bore hole 3D being about to release, and competitively brags about and beat the price down, smoke signals rising on all sides to make 3D TV market, makes numerous consumer at a loss as to what to do.Simultaneously, again due to the disappearance of examination criteria and instrument, also making 3D TV there is no unified examination criteria and instrument from being designed into detect and even sell, causing the consistency of 3D tv product can not be guaranteed, so that often occurring the problem of 3D glasses and complete machine poor fit.
On market today, the 3D TV of main flow is polarization type 3D and shutter 3D two type.And polarisation 3D belongs to the fixing pattern of device and circuit, adjustment and detect also more single, relies on glasses actual viewing conduct detection foundation substantially.And although shutter 3D TV intuitively can detect, because slightly bigger phase deviation does not affect 3D effect, so that there is uneven problem in dispatch from the factory 3D whole set of television and 3D glasses phase place, and interoperability is very poor.The different complete machine of such as same plant produced is with supporting another kind of shutter 3 D glasses or a kind of shutter 3 D glasses to the complete machine of the another kind of model often very poor situation even having no 3D effect of appearance effect, and this is that standard and detecting instrument lack the imbody caused.
Between current debugging shutter 3D whole set of television and 3D glasses, the method for phase place is mainly by observation 3D picture or 3D short-movie and by software correction phase place.But, because the 3D effect of subjective judgement often accurately can not judge difference at wider phase deviation range, therefore be difficult to find the point of phase place adjustment accurately and cannot phase deviation be judged.That is, by the effect of direct vision as detection means, what obtain is the roughly judgement of a relative broad range, judges also poor far from accurate adjustment.Such as, left eye see 10% and 20% of eye image be difficult to distinguish clearly because human eye between the cooperation phase region of 3D image in, have between no small phase region and cannot strictly distinguish its difference.For this reason, the benchmark that the point needing searching one desirable confirms as shutter 3D TV 3D effect.Though there are at present some methods through the brightness of 3D glasses test black and white picture can the degree of judgment bias roughly, but the efficiency that the mode delaying detection makes phase place adjust be extremely low, and cannot realize phase valuation accurately.

Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
With reference to the structural representation that Fig. 1, Fig. 1 are debugging apparatus first embodiment of 3D synchronizing signal phase place of the present invention.
This debugging apparatus comprises:
Receiver module 10, for receiving the field system chronizing impulse signal that 3D display device sends;
Phase shift processing module 20, for carrying out phase shift process by field system chronizing impulse signal;
Output module 30, for exporting the field system chronizing impulse signal after phase shift process to 3D glasses;
Judge module 40, when the image shown by the 3D display device presented by 3D glasses images of left and right eyes eyeglass comprises 1/2nd left-eye image and 1/2nd eye image, the phase place of the field system chronizing impulse signal after the phase shift process according to debugging apparatus, judges that whether 3D display device is synchronous with 3D glasses.
In the present embodiment, the debugging apparatus of the 3D synchronizing signal phase place provided by wired mode, can be connected with 3D glasses, and is seated on the mirror holder of 3D glasses, carries out reception and the transmission of field sync signal; Also debugging apparatus can be placed in outside 3D display device and 3D glasses, wirelessly carry out reception and the transmission of field sync signal with 3D display device and 3D glasses.By this debugging apparatus, the signal that can send 3D display device carries out the adjustment of continuous print phase place.
When 3D picture play by 3D display device, usually can send a field system chronizing impulse signal, this field system chronizing impulse signal is wirelessly launched, and this is the origin identification position of field sync signal.After receiving this field sync signal by shutter 3 D glasses, can the switching of control 3D glasses images of left and right eyes liquid crystal shutter, realize synchronous with between 3D glasses of shutter 3D display device with this.
In the present embodiment, when 3D picture play by 3D display device, and wirelessly launching site synchronization pulse time, before this field system chronizing impulse signal is sent to 3D glasses, first by the receiver module 10 of debugging apparatus, this field system chronizing impulse signal is received, namely by debugging apparatus, field system chronizing impulse signal is blocked, make it directly not be sent to 3D glasses, and by debugging apparatus, field system chronizing impulse signal is sent to 3D glasses.That is, debugging apparatus receives only the field system chronizing impulse signal that 3D display device sends; And 3D glasses receive only the field system chronizing impulse signal that debugging apparatus sends.
After receiver module 10 receives the field system chronizing impulse signal that 3D display device sends, by phase shift processing module 20, continuous print phase shift process is carried out to it, in the process of phase shift process, by output module 30, the field system chronizing impulse signal after phase shift process is sent to 3D glasses.Now, need to be judged by 3D glasses, namely the image shown by 3D display device that now 3D glasses images of left and right eyes eyeglass presents is judged, whether be the image comprising 1/2nd left-eye image and 1/2nd eye image, in the present embodiment, this state can be defined as half image display status.When being in half image display status, being a line of demarcation in the centre of 1/2nd left-eye image and 1/2nd eye image, being positioned at 1/2nd left-eye image on both sides, line of demarcation and 1/2nd eye image and being gradual change and symmetrical; This half image display status easily identifies, and has uniqueness.
When the image that 3D glasses images of left and right eyes eyeglass presents includes the image of 1/2nd left-eye image and 1/2nd eye image, when namely reaching half image display status, synchronism between 3D display device and 3D glasses is the poorest, now, debugging apparatus be sent to the phase place of the field system chronizing impulse signal of 3D glasses and between 3D display device and 3D glasses, synchronism is the best time phase deviation be 90 degree.
Carrying out in continuous print phase shift processing procedure to field system chronizing impulse signal, debugging apparatus can show a numerical value in real time.In the present embodiment, when judging to reach half image display status by 3D glasses, numerical value as shown in debugging apparatus is 0, the phase place of the field system chronizing impulse signal that the 3D display device received by debugging apparatus sends then is described, be phase place when 3D display device and 3D glasses synchronism are the best, thus namely can judge that the synchronism of 3D display device and 3D glasses is for best by judge module 40.
If in phase shift processing procedure, when reaching half image display status, numerical value as shown in debugging apparatus is not 0, then the side-play amount of phase place when namely this numerical value can represent that the phase place of the field system chronizing impulse signal that the 3D display device received by debugging apparatus sends and 3D display device and 3D glasses synchronism are the best.In the present embodiment, shown numerical value is larger, then the phase place of the field system chronizing impulse signal that 3D display device sends is described, the side-play amount of phase place when being the best with 3D display device and 3D glasses synchronism is larger.According to this side-play amount, just can enter horizontal phasing control to 3D display device by software design patterns, namely adjust the phase place of the field system chronizing impulse signal that it sends.
The embodiment of the present invention, is received the field system chronizing impulse signal of 3D display device transmission, field system chronizing impulse signal is carried out phase shift process, and the field system chronizing impulse signal after phase shift process is sent to 3D glasses by debugging apparatus; By 3D glasses, judge that the synchronism of 3D display device and 3D glasses is the poorest phase point, namely when the image shown by display device that now 3D glasses images of left and right eyes eyeglass presents is the image comprising 1/2nd left-eye image and 1/2nd eye image, by the numerical value shown by debugging apparatus, judge whether the synchronism of 3D display device and 3D glasses is best.Like this, the detection of 3D synchronizing signal phase place can be made more quick and precisely, thus guarantee the synchronism passing judgment on 3D display device and 3D glasses more exactly.
With reference to the structural representation that Fig. 2, Fig. 2 are the phase shift processing module shown in Fig. 1.
Phase shift processing module 20 comprises:
Filtering submodule 21, for receive 3D display device send field system chronizing impulse signal after, filtering is carried out to field system chronizing impulse signal, obtains primary field synchronization pulse;
Field sync signal is formed and process submodule 22, for modulating primary field synchronization pulse, forming field sync signal, and carrying out Continuous phase shifting process to field sync signal.
The field system chronizing impulse signal that 3D display device sends, after receiver module 10 reception of debugging apparatus, first filtering submodule 21 can carry out the process of filtering carrier wave to it, at this moment a primary field synchronization pulse processed after filtering can be obtained, and in the middle of the process of received field synchronization pulse, have a fixing phase delay, when the phase pushing figure of calculated field synchronizing signal afterwards, need the impact considering this phase delay, namely on the basis of original regulated phase pushing figure, add the amount of delay of fixing phase delay, at this moment the obtained true phase-offset amount being actual field sync signal.
To be formed by field sync signal and processing module 22 pairs of primary field synchronization pulses are modulated, be used for carrying out synchronous and that duty ratio is larger field sync signal with 3D glasses even if it is formed, in the present embodiment, the field sync signal into duty ratio 50% can be exported, then continuous print phase shift process is carried out to exported field sync signal.In the present embodiment, when carrying out phase shift process to field sync signal, can be realized by different modes, such as, can utilize the step-length of the good phase shift of software set in debugging apparatus, and come by trigger mechanisms such as external buttons; Can also utilize the mode of hardware, namely arranging one can the driver plate of control phase, freely can be controlled the step-length of phase shift by the angle of revolving dial.With upper type, its operation principle is increases by a resistance in internal circuit, and namely the size of adjusting resistance value can realize the size of the phase pushing figure adjusting field sync signal; Through the RC integral contrast process of internal circuit, the field sync signal of the rise edge delay formed, is the field sync signal after phase shift Treatment stations.Certainly, in order to find the position of half image display status more accurately, the step-length of phase shift should be made little as far as possible.
After the field system chronizing impulse signal receiving the transmission of 3D display device, filtering is carried out to field system chronizing impulse signal, obtains primary field synchronization pulse; Primary field synchronization pulse is modulated, forms field sync signal, and by equipment such as external regulating key or driver plates, Continuous phase shifting process is carried out to field sync signal by the mode of software or hardware.Processing without the need to adjusting software, the phase place of the synchronizing signal being sent to 3D glasses can be adjusted arbitrarily, further ensure the measuring and adjustation of the phase place that can make 3D synchronizing signal more quick and precisely.
With reference to the structural representation that Fig. 3, Fig. 3 are the output module shown in Fig. 1.
Output module 30 comprises:
Field system chronizing impulse signal forms submodule 31, for the rising edge according to the field sync signal after phase shift process, forms the field system chronizing impulse signal after phase shift process;
Output sub-module 32, for exporting the field system chronizing impulse signal after phase shift process to 3D glasses.
Field sync signal is being carried out in the process of phase shift, image as shown in the 3D display device that 3D glasses images of left and right eyes eyeglass presents comprises 1/2nd left-eye image and 1/2nd eye image, when namely reaching half image display status, the phase pushing figure of the field sync signal according to debugging apparatus, add the fixing phase delay amount produced when receiver module 10 receives the field system chronizing impulse signal that 3D display device sends, namely obtain the phase pushing figure of actual field sync signal.According to the phase pushing figure of the field sync signal of obtained reality, namely the rising edge of the field sync signal after phase shift process can postpone the size of a phase pushing figure accordingly, and at this moment field system chronizing impulse signal formation submodule 31 can form the field system chronizing impulse signal after phase shift process.
During each rising edge of the field sync signal after phase shift process, output sub-module 32 exports this signal to 3D glasses, the signal exported is the field system chronizing impulse signal after phase shift process, and the pulse duration of the field system chronizing impulse signal that itself and 3D display device send is identical and phase place is different.In the present embodiment, if debugging apparatus is connected with 3D glasses by wired mode, and time on the mirror holder being seated in 3D glasses, field system chronizing impulse signal after phase shift process directly can export the receiving terminal of 3D glasses to, when after the field system chronizing impulse signal after 3D glasses receive phase shift process, can control the shutter release of its images of left and right eyes, thus it is synchronous to realize between its with 3D display device.
After being judged that by 3D glasses the image shown by current 3D display device is half image display status, during each rising edge of the field sync signal after phase shift process, export the field system chronizing impulse signal after this phase shift process to 3D glasses, after receiving the field system chronizing impulse signal after phase shift process for 3D glasses, control the shutter release of its images of left and right eyes, thus it is synchronous to realize between its with 3D display device.This just further ensure that can make 3D synchronizing signal phase place detection more quick and precisely, thus further guarantee the synchronism judging 3D display device and 3D glasses more exactly.
With reference to the structural representation that Fig. 4, Fig. 4 are debugging apparatus second embodiment of 3D synchronizing signal phase place of the present invention.
In the present embodiment, output module 30 also comprises:
High frequency modulated submodule 33, for carrying out high frequency modulated by the field system chronizing impulse signal after phase shift process.

After high frequency modulated is carried out to the field system chronizing impulse signal after phase shift process, rise on each of which along time, export this signal to 3D glasses, now, the transmission of pulse signal can be carried out by radio wave or infrared mode.Because 3D display device and debugging apparatus all carry out the transmission of respective pulse signal by radio wave or infrared mode, like this, just conflict may be produced between these two pulse signals, in the present embodiment, can process by blocking isolation, decay guiding or the mode of encryption decode, to reach the object mutually can not disturbed between two pulse signals.
As being placed in outside 3D glasses by debugging apparatus, and when wirelessly carrying out the reception of signal and send, before the field system chronizing impulse signal after phase shift process is sent to 3D glasses, high frequency modulated is carried out to the field system chronizing impulse signal after phase shift process.This just provides better basis for the field system chronizing impulse signal laggard line phase migration processing after 3D glasses receive phase shift process, thus realizes the quick of the detection of 3D synchronizing signal phase place and accuracy better.

Field sync signal is being carried out in the process of phase shift, image as shown in the 3D display device that 3D glasses images of left and right eyes eyeglass presents comprises 1/2nd left-eye image and 1/2nd eye image, when namely reaching half image display status, the phase pushing figure of the field sync signal according to debugging apparatus, adding the fixing phase delay amount produced when receiving the field system chronizing impulse signal that 3D display device sends, namely obtaining the phase pushing figure of actual field sync signal.According to the phase pushing figure of the field sync signal of obtained reality, namely the rising edge of the field sync signal after phase shift process can postpone the size of a phase pushing figure accordingly, at this moment can form the field system chronizing impulse signal after phase shift process.
During each rising edge of the field sync signal after phase shift process, export this signal to 3D glasses, the signal exported is the field system chronizing impulse signal after phase shift process, and the pulse duration of the field system chronizing impulse signal that itself and 3D display device send is identical and phase place is different.In the present embodiment, if debugging apparatus is connected with 3D glasses by wired mode, and time on the mirror holder being seated in 3D glasses, field system chronizing impulse signal after phase shift process directly can export the receiving terminal of 3D glasses to, when after the field system chronizing impulse signal after 3D glasses receive phase shift process, can control the shutter release of its images of left and right eyes, thus it is synchronous to realize between its with 3D display device.
After being judged that by 3D glasses the image shown by current 3D display device is half image display status, during each rising edge of the field sync signal after phase shift process, export the field system chronizing impulse signal after this phase shift process to 3D glasses, after receiving the field system chronizing impulse signal after phase shift process for 3D glasses, control the shutter release of its images of left and right eyes, thus it is synchronous to realize between its with 3D display device.This just further ensure that can make 3D synchronizing signal phase place detection more quick and precisely, thus further guarantee the synchronism judging 3D display device and 3D glasses more exactly.
With reference to the schematic flow sheet that Fig. 8, Fig. 8 are detection method second embodiment of 3D synchronizing signal phase place of the present invention.
In the present embodiment, before execution step S24, also comprise:
Step S25, the field system chronizing impulse signal after phase shift process is carried out high frequency modulated by debugging apparatus.
In the present embodiment, as debugging apparatus being placed in outside 3D glasses, and when wirelessly receiving and send signal, when after the field system chronizing impulse signal obtain corresponding phase shift process according to the rising edge of the field sync signal after phase shift process after, need to carry out high frequency modulated to it, namely between its high period, load high frequency carrier, and stop when its low level loading high frequency carrier and keeping low level.In the present embodiment, this high frequency modulated can be programmed by CPU and be realized, and also can be realized by the mode of voltage-controlled oscillator.
After high frequency modulated is carried out to the field system chronizing impulse signal after phase shift process, rise on each of which along time, export this signal to 3D glasses, now, the transmission of pulse signal can be carried out by radio wave or infrared mode.Because 3D display device and debugging apparatus all carry out the transmission of respective pulse signal by radio wave or infrared mode, like this, just conflict may be produced between these two pulse signals, in the present embodiment, can process by blocking isolation, decay guiding or the mode of encryption decode, to reach the object mutually can not disturbed between two pulse signals.
As being placed in outside 3D glasses by debugging apparatus, and when wirelessly carrying out the reception of signal and send, before the field system chronizing impulse signal after phase shift process is sent to 3D glasses, high frequency modulated is carried out to the field system chronizing impulse signal after phase shift process.This just provides better basis for the field system chronizing impulse signal laggard line phase migration processing after 3D glasses receive phase shift process, thus realizes the quick of the detection of 3D synchronizing signal phase place and accuracy better.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
