Please refer to Fig. 3, it is the calcspar of device one embodiment of calibration time clock of the present invention.As shown in the figure, the device 1 of calibration time clock of the present invention is to be applicable to an anaglyph spectacles, and it can comprise a receiving element 10, a timer 11 and a processing module 12.Wherein, the shutter of this anaglyph spectacles liquid crystal (Liquid Crystal) of can arranging in pairs or groups, do by the mode of controlling penetrability and cover: that is, when the penetrability of liquid crystal is relatively transparent, namely generally said unlatching when reality is implemented; Otherwise, when the penetrability of liquid crystal is relatively opaque, general said closing when reality is implemented namely.In some preferred embodiments, the RC oscillator (RC oscillator) that the shutter of this anaglyph spectacles can be arranged in pairs or groups and be had low cost and low power consumption advantage carries out the switching of the shutter of anaglyph spectacles.
When anaglyph spectacles operated at the beginning, receiving element 10 was to receive one first clock signal 201 that is 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 ends send.Processing module 12 can be electrically connected receiving element 10 and timer 11, and this processing module 12 can comprise microprocessor (Micro-Processing Unit) or central processing unit (Central Processing Unit, CPU).After receiving element 10 receives the first clock signal 201, processing module 12 can calculate according to the first clock signal 201 that receiving element 10 is received continuously the cycle of this first clock signal, is made as cycle of one second clock signal 111 in anaglyph spectacles identical with the cycle of the first clock signal 201.Thus, processing module 12 can be controlled the shutter that timer 11 switches anaglyph spectacles.
Yet, when if the communication channel that image documentation equipment 2 and anaglyph spectacles are asked is subject to hindering, that is to say, when receiving element 10 does not receive the first clock signal 201 that is sent by the signal transmitter unit 20 in external image equipment 2, cause communicating interrupt such as but not limited to the factor because of signal interference, weak output signal or variation of ambient temperature etc.And processing module 12 can be after through a Preset Time (such as but not limited to the cycle of 30 the second clock signals 111), the first clock signal 201 and the second clock signal 111 are compared, produce a mean deviation amount with correspondence, and the cycle of adjusting the second clock signal 111 according to this mean deviation amount with synchronously to the cycle of the first clock signal, enable to complete calibration.Thus, processing module 12 just can according to the cycle of calibration the second clock signal 111 later, be carried out the switch of anaglyph spectacles shutter.
In some preferred embodiments, timer 11 is that the time clock of counting the second clock signal 111 produces a count value 112 with correspondence.When the cycle of cycle of 12 pairs of the first clock signals 201 of processing module and the second clock signal 111 compared, processing module 12 was to draw mean deviation amount 301 according to count value 112.In addition, preferably, when every cycle through second clock signal 111 of timer 11, processing module 12 count value 112 (such as but not limited to count value 112 is made zero) of just resetting one is reseted number of times 302 with record, and being no more than a default size of number of times (such as but not limited to 30 times) of reseting, according to count value 112 with reset number of times 302 and draw mean deviation amount 301.
Incidentally be that the first clock signal 201 and the second clock signal 111 have all comprised left shutter release sequential and the right shutter release sequential of anaglyph spectacles.And should understand person with usual knowledge in their respective areas of the present invention, those who are familiar with this art work as can become an integrated module in conjunction with above-mentioned functional module arbitrarily, or is split into the thin section of each function unit, and end is seen the convenience in design and is decided.
Although aforementioned in the process of device of explanation calibration time clock of the present invention, the concept of the method for calibration time clock of the present invention also is described simultaneously, for ask clear for the purpose of, below still separately illustrate the process flow diagram detailed description.
Please refer to Fig. 4, it is the process flow diagram of the method for calibration time clock of the present invention.In an embodiment of the present invention, the present invention discloses a kind of method that is implemented in the calibration time clock of anaglyph spectacles.The method of this calibration time clock comprises the following step.Step 41: receive one first clock signal that an image documentation equipment sends.When reality is implemented, can be roughly the same noted earlier, received the first clock signal that is sent by the signal transmitter unit in external image equipment by receiving element.Step 42: with one second clock signal in this anaglyph spectacles synchronously to cycle of this first clock signal.Step 43: after through a Preset Time (such as but not limited to the cycle of 30 the second clock signals), the cycle of this first clock signal and the cycle of this second clock signal are compared, produce a mean deviation amount with correspondence.Again, step 44: adjust the cycle of this second clock signal according to this mean deviation amount with the synchronous cycle to this first clock signal, just can complete calibration accordingly.
Wherein, in some preferred embodiments, before step 43, can comprise the following step: calculated the cycle of this first clock signal according to this first clock signal of receiving continuously by this processing module, the cycle with this second clock signal in anaglyph spectacles is made as identical with the cycle of this first clock signal according to this.
In addition, understand for asking clear, below will separately lift a specific embodiment and explain above-mentioned several step, and arrange in pairs or groups graphic explanation it.
See also Fig. 5, it is the process flow diagram of a specific embodiment of the method for calibration time clock of the present invention.The method of this calibration time clock comprises the following step.Step 51: when the user watches stereopsis, anaglyph spectacles time clock calibration beginning.When reality is implemented, as step 52: frequency and the cycle that can preset timer.for instance, in this specific embodiment, the left and right image switching frequency of case of external image documentation equipment is 60Hz, the count value of one-period is 1.5Mhz/60=25000, for the timer that makes anaglyph spectacles receives the shutter opening signal at least one cycle in its predetermined period, therefore, the signal period that the default cycle of the timer of anaglyph spectacles must launch greater than external image equipment, in the middle of the present embodiment, the timer period count value of anaglyph spectacles can be made as 1.5Mhz/30=50000, in practical application, the timer predetermined period of this anaglyph spectacles can be adjusted according to the signal specification of external image equipment.Step 53: when receiving element received the left shutter opening signal that is sent by the signal transmitter unit in external image equipment for the first time, processing module read the count value of timer.Step 54: receive for the second time left shutter opening signal when receiving element has, processing module can read count value and the execution in step 55 of timer, and if not, execution in step 57.Consider actual conditions, because of the error that hardware components and microprocessor computing cause, receive for the first time with for the second time that the value that " left shutter opening " Clock of signal differs is assumed to be 25497.In step 55: processing module can be made as 25497 with the cycle of timer, makes the timer period of anaglyph spectacles and the cycle synchronisation of the left shutter opening signal that the signal transmitter unit in external image equipment sends.Then, step 56: processing module returns 0 with the number of times of reseting of timer, gets back to step 53.Above-mentioned be utilize for the first time with the synchronizing signal of receiving for the second time (for example, left shutter opening signal, left shutter close signal, right shutter opening signal and right shutter close signal) and the count value of timer between relation, understand the gap of both time clock, and be made as cycle of timer in anaglyph spectacles identical with this synchronizing signal by this.
Then, as step 53, when receiving left shutter opening signal for the third time, processing module reads the count value of timer, it should be noted that owing to being to receive for the third time left shutter opening signal, thus skips steps 54, execution in step 57.In step 57, processing module can be noted down the number of times of reseting of timer, supposes that reseting number of times is 1 time this moment.Then carry out step 58: when timer reset number of times more than or equal to 30 times, execution in step 59, otherwise, then resumes step 53.Iteration so repeatedly is because the side-play amount of one-period is too little, is not enough to as the reference of proofreading and correct the anaglyph spectacles time clock.Therefore, the present invention is after several cycles of accumulation, with total drift amount/periodicity, according to this resulting mean deviation amount is gone to adjust the cycle of timer, and then reaches the purpose of proofreading and correct the anaglyph spectacles time clock.
In step 59, with the count value of counter/reset number of times, obtain a mean deviation amount, note down through experimental data, after the reseting number of times and equal 30 times (approximately 500 microseconds) of timer, the count value of the timer that reads is 90, and the time clock that can obtain the skew of image documentation equipment and anaglyph spectacles is 90/30=3.Then carry out step 60: adjust the cycle of timer according to mean deviation amount (being 3 in this embodiment), it is 25497+3=25500 that the cycle of timer is proofreaied and correct.Therefore, in timer this moment, new clock signal just can be accordingly to 3 Clock of post-equalization.Above-mentioned data only are used to provide reference, when reality is implemented, according to the different mean deviation amounts clock signal of forward/backward check timer correspondingly.Thus, the calibration of anaglyph spectacles time clock is in order to do completing.
Please refer to Fig. 6, it is to adjust schematic diagram according to the shutter sequential of Fig. 5.When initial, due to the time clock of external image equipment or not identical with the time clock of anaglyph spectacles, therefore must be first that cycle of clock signal in timer in anaglyph spectacles is made as cycle of the synchronizing signal of sending with the signal transmitter unit is identical.As shown in the figure, in the T0 cycle, receive for the first time the first clock signal when receiving element, processing module reads the count value of counter, if this count value is 1; And receive for the second time the first clock signal when receiving element, processing module reads the count value of counter, if this count value is 25497.Thus, the cycle that processing module just can calculate synchronizing signal is 25497, and sets according to this cycle of clock signal in timer.
Please refer to Fig. 7, it is to adjust schematic diagram according to the shutter sequential of Fig. 5.Whenever the cycle of timer through second clock signal, processing module replacement count value (for example returning 0) is reseted number of times with record one.Processing module default is reseted the size of number of times (such as but not limited to 30 times to be no more than one, that is the T31 cycle of the second clock signal), calculate a mean deviation amount (90/30=3) according to the count value that reads (for example 90), that is to say, each cycle mean deviation 3 Clock, therefore should adjust the cycle of timer is 25497+3=25500, so that the cycle of cycle synchronisation to the first clock signal of the second clock signal, and then complete calibration.
The detailed embodiment of each above-mentioned step had described in detail in the narration of the device of the calibration time clock of front, just repeated no more at this.
In sum, the devices and methods therefor of calibration time clock proposed by the invention can be in response to the problem of the time clock that factor causes such as signal interference, weak output signal or environmental factor (such as temperature variation) skew, utilize synchronizing signal that image documentation equipment sends to adjust the sequential of the shutter release of anaglyph spectacles, cause flicker when avoiding shutter to switch.Allow the user discover flicker less than shutter, and then promote the image rating quality that the user uses active stereo glasses.Found by the actual experiment data, still can keep approximately 8.33 seconds normal rating time through the maximum offset after calibration, therefore the devices and methods therefor of calibration time clock proposed by the invention can use RC oscillator low-cost and low power consumption, the liquid crystal that replaces expensive and high power consumption, and then the saving manufacturing cost, and can improve the possibility that the user buys anaglyph spectacles.
The above is only illustrative, but not is restricted person.Anyly do not break away from spirit of the present invention and category, and to its equivalent modifications of carrying out or change, all should be contained in claim scope of the present invention.
