Because the position difference of right and left eyes, so also some difference of the viewed image of right and left eyes.If make left eye only see the required information of seeing of left eye, right eye only can be seen the information of right eye, can cheat brain and produce stereoscopic vision.Transmit the mode of binocular stereoscopic image at present, mainly the image of right and left eyes is arranged with level or vertical mode, re-use the polarising glass sight and make left eye only see the image information of left eye, right eye only sees that the image information of right eye is to present 3-D view.
Yet, when using polarising glass (Polarization glasses) to view and admire three-dimensional film, often light leak (Light leakage) phenomenon is arranged because of glasses, make people when watching three-dimensional film, feel the picture brightness inequality, image is interlaced and problem such as ghost, cause people to feel dizzy, uncomfortable situation such as keck, it is a lot of for the 3-D view quality evaluation to influence people.This light leakage phenomena is because of the difference of polarising glass designing technique in fact, and causes left eye to see the image information of a spot of right eye, and right eye is seen the image information of a spot of left eye.
Therefore, category of the present invention is to provide a kind of and produces the adjusting device and the method thereof of correct output by the revisal computing, to address the above problem.
Summary of the invention
It is a kind of in order to adjust the adjusting device and the method thereof of 3-D view that a category of the present invention is to provide.
Another category of the present invention is to provide a kind of and produces correct adjusting device that exports a display floater to and method thereof by the revisal computing.
According to a preferred embodiment, adjusting device of the present invention is in order to adjust 3-D view to export a display floater to.This 3-D view is observed by staggered N first and is seen image line and N second observes and see that image line forms, and N is one greater than 1 integer.This adjusting device comprises an adjusting module (Adjusting module), one first modular converter (Converting module), one second modular converter, one first decision module (Determining module), one second decision module, a line register (Line buffer) and a distribution module (Distributing module).
Its respective outer side edges of this adjusting module receives i first and observes see image line (First-eye-viewed image line) and i group distributed first observe over sight (OS) light value (Distributed first-eye-viewed leakage values) and observe and see image line to this display floater to produce i adjusted first, and what the i group had been distributed first observes the over sight (OS) light value and observe according to (i-1) individual second and see that image line (Second-eye-view image line) produces.Or this adjusting module receives j second and observes see image line and j group distributed second observe over sight (OS) light value (Distributed second-eye-viewed leakage values) and observe and see image line to this display floater to produce j adjusted second, and what the j group had been distributed second observes the over sight (OS) light value and observe according to j first and see that image line produces.Wherein i is the integer of scope from 2 to N, and j is the integer of scope from 1 to N.
This its respective outer side edges of first decision module receives j adjusted first and observes and see image line.Its respective outer side edges reception of this second decision module (i-1) individual adjusted second observes and sees image line.This first decision module is seen image line and a plurality of second observing over sight (OS) light value (Pre-stored second-eye-viewed leakage values) and determine j group second to observe over sight (OS) light value (Second-eye-viewed leakage values) of prestoring in order to observe according to j adjusted first.And this second decision module is seen image line and a plurality of first observing over sight (OS) light value (Pre-stored first-eye-viewed leakage values) and determine i group first to observe over sight (OS) light value (First-eye-viewed leakage values) of prestoring in order to observe according to (i-1) individual adjusted second.Wherein, the light leak value that prestores refers to that left eye receives the information of right eye or the information that right eye receives left eye, that is left eye information spill and leakage to right eye or right eye information spill and leakage to left eye.
In addition, because most display floater all has the gamma characteristic, therefore adjusting device of the present invention further comprises a gray scale linear transformation (Gray linearity conversion) step, that is is carried out by this first modular converter and this second modular converter.This first modular converter is electrically coupled between this adjusting module and this first decision module, and is electrically coupled to this display floater.This second modular converter is electrically coupled between this adjusting module and this second decision module, and is electrically coupled to this display floater.The j individual adjusted first that this first modular converter is exported by this adjusting module in order to reception observes and sees image line, and according to the characteristic of this display floater j adjusted first is observed and to see that image line is converted to j switched first and observes and see image line, wherein j switched first observes and sees that image line replaces j that leading portion mentions adjusted first and observes and see image line, and exports this display floater and this first decision module to.And, (i-1) individual adjusted second that this second modular converter is exported by this adjusting module in order to reception observes and sees image line, and according to the characteristic of this display floater (i-1) individual adjusted second observed and to see that image line is converted to (i-1) individual switched second and observes and see image line, wherein (i-1) individual switched second observes and sees that image line replaces (i-1) individual adjusted second that leading portion mentions and observes and see image line, and exports this display floater and this second decision module to.
This its respective outer side edges of line register receives alternately and deposits that j group second is observed the over sight (OS) light value and i group first is observed the over sight (OS) light value.Its respective outer side edges of this distribution module receives the j group second that is deposited in this line register and observes the over sight (OS) light value and second observe the over sight (OS) light value to produce about what j second observed that the j group of seeing image line distributed.Or receiving the i group first be deposited in this line register observes the over sight (OS) light value and first observes the over sight (OS) light value to produce about what i first observed that the i group of seeing image line distributed.
In other words, when this adjusting module received a row image line, this distribution module will get this row image light leak value that is stored in this line register again with weight allocation the image light leak value of having distributed sent this adjusting module to.This adjusting module promptly is listed as adjusted image line according to the light leak value that image line and this of this reception distributed to produce this.Wherein, this line register this row image light leak value of being stored is handled according to previous column adjusted image line by this first decision module or this second decision module and is got.For example, when this adjusting module receives the 5th row image line (according to this preferred embodiment, this row image line is the 3rd first and observes picture with the aid of pictures), this distribution module also will be stored in the 5th group of light leak value of this line register and distribute the 5th group of light leak value again with certain weight ratio, and send the 5th group of light leak value of having distributed to this adjusting module.This adjusting module promptly according to the 5th row image line that receives and the 5th group of light leak value to produce the adjusted image line of the 5th row (that is the 3rd adjusted first observe picture with the aid of pictures).The 5th group of light leak value handled according to the adjusted image line of the 4th row (that is the 2nd adjusted second observe picture with the aid of pictures) by second decision module and got, and is stored in this line register.Again for example, when this adjusting module receives the 8th row image line (according to this preferred embodiment, this row image line is the 4th second and observes picture with the aid of pictures), this distribution module also will be stored in the 8th group of light leak value of this line register and distribute the 8th group of light leak value again with certain weight ratio, and send the 8th group of light leak value of having distributed to this adjusting module.This adjusting module promptly according to the 8th row image line that receives and the 8th group of light leak value to produce the adjusted image line of the 8th row (that is the 4th adjusted second observe picture with the aid of pictures).The 8th group of light leak value handled according to the adjusted image line of the 7th row (that is the 4th adjusted first observe picture with the aid of pictures) by second decision module and got, and is stored in this line register.Therefore, observe and see image line, then observe according to previous column adjusted second by this second decision module and see image line is handled and get should first observing one group of light leak value seeing image line if this adjusting module receives a certain row first; If this adjusting module receives a certain row second and observes and see image line, then observe according to previous column adjusted first by this first decision module and see image line is handled and get should second observing one group of light leak value seeing image line.
Be noted that according to adjusting device of the present invention, (that is the 1st first observe see image line) there is no the adjusted image line of previous column because the 1st row image line, so the 1st row image line will be directly output as the adjusted image line of the 1st row.In like manner, there is no the next column image line and need to handle because last is listed as adjusted image line (that is last second observe see image line), thus this last be listed as adjusted image line and do not need further to handle by second decision module.
In addition, these a plurality of adjusted image lines can directly export this display floater in principle, but because most display floater all has the gamma characteristic, therefore these a plurality of adjusted image lines need export this display floater and this first decision module and this second decision module to more further through the linear switch process of this gray scale.That is these a plurality of adjusted image lines are converted to switched image line by this first modular converter (if adjusted first observe see image line) or this second modular converter (if adjusted second observe see image line).And this switched image line promptly is sent to this display floater and this first decision module and this second decision module.
In brief, each row image line of this 3-D view all via adjusting, change and export to this display floater, is handled to produce one group of light leak value through these a plurality of decision module again, and weight allocation is for the usefulness of next column image line adjustment again.So circulation is gone down, and disposes up to this 3-D view.
Therefore, adjusting device of the present invention is by distributing the light leak value adjusting the image input of next line, and cooperate the characteristic of display floater change adjusted image input and output to display floater to solve light leak problem and correct display image.
Can be further understood by the following detailed description and accompanying drawings about the advantages and spirit of the present invention.

See also Fig. 1, Fig. 1 is the functional block diagram according to the zeroing device of a preferred embodiment.According to this preferred embodiment, adjusting device 1 of the present invention is in order to adjust 3-D view S to export a display floater 3 to.This 3-D view is observed by staggered N first and is seen image line and N second observes and see that image line forms, and N is one greater than 1 integer.This adjusting device 1 comprises an adjusting module 11, one first modular converter 12, one second modular converter 13, one first decision module 14, one second decision module 15, a line register 16 and a distribution module 17.And this adjusting device 1 also comprises 19,20 and two right and left eyes determining devices 21,22 of two selectors.According to this preferred embodiment, this 3-D view S meets rgb color space, and its picture signal presents with gamma0.45.Therefore, this 3-D view S is before 1 adjusting module 11 is put in this adjustment of input, earlier with a gamma2.2 transducer 18 conversions.In addition, according to this preferred embodiment, first corresponding right eye, second corresponding left eye.
These adjusting module 11 its respective outer side edges receive i first and observe and see watch that image line and i group distributed first observe the over sight (OS) light value and observe and see image line to produce i adjusted first.Or this adjusting module 11 receives j second and observes see image line and j group distributed second observe the over sight (OS) light value and observe and see image line to produce j adjusted second.Wherein i is the integer of scope from 2 to N, and j is the integer of scope from 1 to N.According to this preferred embodiment, this adjusting module 11 is observed i first and is seen watch that image line deducts that the i group distributed first observe the over sight (OS) light value and observe and see image line to produce i adjusted first.In like manner, this adjusting module 11 is observed see image line deducts that the j group distributed second observe the over sight (OS) light value and observe and see image line to produce j adjusted second with j second.
That is when this adjusting module received a row image line, this distribution module will get this row image light leak value that is stored in this line register again with weight allocation the image light leak value of having distributed sent this adjusting module to.This adjusting module promptly is listed as adjusted image line according to the light leak value that image line and this of this reception distributed to produce this.For example, when this adjusting module receives the 5th row image line (according to this preferred embodiment, this row image line be the 3rd first observe see image line), this distribution module also will be stored in the 5th group of light leak value of this line register and distribute the 5th group of light leak value again with certain weight ratio, and send the 5th group of light leak value of having distributed to this adjusting module.This adjusting module promptly according to the 5th row image line that receives and the 5th group of light leak value to produce the adjusted image line of the 5th row (that is the 3rd adjusted first observe see image line).Again for example, when this adjusting module receives the 8th row image line (according to this preferred embodiment, this row image line be the 4th second observe see image line), this distribution module also will be stored in the 8th group of light leak value of this line register and distribute the 8th group of light leak value again with certain weight ratio, and send the 8th group of light leak value of having distributed to this adjusting module.This adjusting module promptly according to the 8th row image line that receives and the 8th group of light leak value to produce the adjusted image line of the 8th row (that is the 4th adjusted second observe see image line).Wherein, this row image light leak value that this line register is stored is handled and is got based on previous column adjusted image line by this first decision module or this second decision module, after more detailed description will be specified in.In addition, this adjusting module produces adjusted image line the image line of each reception is cut one group of corresponding light leak value, cuts the 5th group of light leak value as the 5th row image line of precedent.That is the image line of this reception comprises several pixels, all corresponding light leak value of each pixel, and this adjusting module cuts corresponding light leak value with each pixel of this image line promptly becomes this adjusted image line.In addition, also applicable in 3-D view though previous example is an example with the staggered 3-D view of level with vertical interlaced, needless to say give unnecessary details.
This first modular converter 12 and this second modular converter 13 are electrically coupled between this adjusting module 11 and this selector 19.This selector 19 and be electrically coupled to this first decision module 14, this second decision module 15 and this display floater 3.This selector 19 and be electrically coupled to this right and left eyes determining device 21.This first modular converter 12 is seen image line in order to receive to be observed by the j of this adjusting module 11 outputs adjusted first, and according to the characteristic of this display floater 3 j adjusted first is observed and to see that image line is converted to j switched first and observes and see image line.Similarly, this second modular converter 13 is observed and is seen image line in order to receive (i-1) individual adjusted second by 11 outputs of this adjusting module, and according to the characteristic of this display floater 3 (i-1) individual adjusted second is observed and to see that image line is converted to (i-1) individual switched second and observes and see image line.J individual switched first observes and sees that image line is sent to this display floater 3 and this first decision module 14 subsequently.And (i-1) individual switched second observes and sees that image line is sent to this display floater 3 and this second decision module 15 subsequently.In addition, according to this preferred embodiment, though the signal of these adjusting module 11 outputs is transferred into this first modular converter 12 and this second modular converter 13 simultaneously, and this selector 19 also receives the picture signal by this first modular converter 12 and 13 outputs of this second modular converter simultaneously, but this selector 19 according to the signal of right and left eyes determining device 21 of electric coupling, correctly correct picture signal is exported to this display floater 3 and this first decision module 14 and this second decision module 15.
For example, (that is the 3rd adjusted first observe see image line) is to this first modular converter 12 and this second modular converter 13 if the adjusted image line of this adjusting module 11 outputs the 5th row, according to the present invention, the switched image line of this first modular converter 12 the 5th row will change out according to the invention, but this second modular converter 13 is also changed out simultaneously one and is not met picture signal of the present invention.Both all are transferred into this selector 19 for this.This selector 19 will selectively be sent out the 5th switched image line of row and abandon the picture signal that is sent by this second modular converter 13 according to the signal of this right and left eyes determining device 21.Anti-, (that is the 4th adjusted second observe see image line) is to this this first modular converter 12 and this second modular converter 13 if the adjusted image line of this adjusting module 11 outputs the 8th row, according to the present invention, the switched image line of this second modular converter 13 the 8th row will change out according to the invention, but this first modular converter 12 is also changed out simultaneously one and is not met picture signal of the present invention.Both also all are transferred into this selector 19 for this.This selector 19 will selectively be sent out the 8th switched image line of row and abandon the picture signal that is sent by this first modular converter 12 according to the signal of this right and left eyes determining device 21.
According to this preferred embodiment, set up a gray scale intensities transformation curve at the characteristic of this display floater 3, and set up a gray scale linearity conversion table according to this gray scale intensities transformation curve.See also Fig. 2 A and Fig. 2 B, Fig. 2 A is the gray scale intensities transformation curve of expression according to this preferred embodiment.Fig. 2 B is the gray scale linearity conversion table of expression according to this preferred embodiments.
This gray scale intensities transformation curve comprises a left eye gray scale intensities transformation curve and a right eye gray scale intensities transformation curve.By a polarising glass and the plane of polarization plate module that cooperatively interacts, use measuring instrument to measure the gray value of images of left and right eyes of this display floater 3 to the brightness transition curve, shown in Fig. 2 A.Its metering system can be closed eye image information earlier, only stays left-eye image information, measures corresponding brightness to set up the gray scale intensities transformation curve of this left eye from the left eye polarising glass again.In like manner, left-eye image information is closed, only stay eye image information, measure corresponding brightness to set up the gray scale intensities transformation curve of this right eye from the right eye polarising glass again.And, according to this gray scale intensities transformation curve, be that 255 o'clock less brightness values are made as the images of left and right eyes maximum brightness value in gray value with images of left and right eyes, and according to set up this gray scale linearity conversion table, shown in Fig. 2 B.This gray scale linearity conversion table comprises a left eye gray scale linearity conversion table and a right eye gray scale linearity conversion table.
In addition, see also Fig. 2 C, the notion that Fig. 2 C produces for expression gray scale linearity conversion table.Shown in Fig. 2 C, the gray value of input is 35, via gray scale linearity conversion table table look-up can get one the conversion after output, its gray value is 32.Output after this conversion inputs to panel, and because of panel characteristics, last output valve is 35, i.e. the value of initial input.That is, if with panel characteristics with function representation, then gray scale linearity conversion table is the inverse function of this function.Therefore, via the conversion of the gray scale linearity input is correctly exported.The gray scale linearity conversion table of Fig. 2 B i.e. notion foundation according to this.
Therefore, this first modular converter 12 adjusted image line that will be sent by this adjusting module 11 becomes switched image line according to the right eye gray scale linearity translation table of Fig. 2 B.Similarly, this second modular converter 13 adjusted image line that will be sent by this adjusting module 11 becomes switched image line according to the left eye gray scale linearity translation table of Fig. 2 B.In addition, the problem that this first modular converter 12 and this second modular converter 13 are exported simultaneously repeats no more as described above.
According to this preferred embodiment, this first decision module 14 and this second decision module 15 are electrically coupled to this selector 19 and this selector 20 respectively.These first decision module, 14 its respective outer side edges receive j switched first and observe and see image line.This second decision module 15 its respective outer side edges reception (i-1) individual switched second observe and see image line.This first decision module 14 is seen image line and a plurality of second observing the over sight (OS) light value and determine j group second to observe the over sight (OS) light value of prestoring in order to observe according to j switched first.And this second decision module 15 is seen image line and a plurality of first observing the over sight (OS) light value and determine i group first to observe the over sight (OS) light value of prestoring in order to observe according to (i-1) individual switched second.That is this first decision module 14 receives a certain row switched first and observes and see image line, and second observes the light leak value of seeing and determine next column second to observe the light leak value of seeing according to what should a plurality ofly prestore immediately.And this second decision module 15 receives a certain row switched second and observes and see image line, and first observes the light leak value of seeing and determine next column first to observe the light leak value of seeing according to what should a plurality ofly prestore immediately.For example, this first decision module 14 receives the switched image line of the 7th row (that is the 4th switched first observe see image line), and immediately according to this a plurality of prestore second observe the light leak value that the over sight (OS) light value determines the 8th row image line (that is the 4th group second observe the over sight (OS) light value).Again for example, this second decision module 15 receives the switched image line of the 6th row (that is the 3rd switched second observe see image line), and immediately according to this a plurality of prestore first observe the light leak value that the light leak value of seeing determines the 7th row first to watch (that is the 4th group first observe the over sight (OS) light value).Wherein, the light leak value that prestores refers to that left eye receives the information of right eye or the information that right eye receives left eye, that is left eye information spill and leakage to right eye or right eye information spill and leakage to left eye.Its metering system is detailed as described later, and no longer this gives unnecessary details.
In addition, though this first decision module 14 and this second decision module 15 receive the picture signal that is transmitted by this selector 19 simultaneously, and determine one group of light leak value separately and be sent to this selector 20, but this selector 20 will according to the signal of right and left eyes determining device 22 of electric coupling, correctly one group of correct light leak value is transmitted and is stored in this line register 16.Class is with aforesaid selector 19, and this selector 20 is according to the signal of this right and left eyes determining device 22, and selectively wherein one group of light leak value transmits and is stored in this line register, and another group light leak value is abandoned.According to this preferred embodiment, each these a plurality of second gray value observing in the corresponding a plurality of gray values of over sight (OS) light value that prestore.This first decision module 14 judges which gray value mates j individual switched first and observes the pixel of seeing image line, and determine subsequently one group to gray value that should a plurality of couplings prestore second observe the over sight (OS) light value, observe the over sight (OS) light value as j group second.And, each these a plurality of first gray value observing in the corresponding a plurality of gray values of over sight (OS) light value that prestore, this second decision module 15 judges which gray value coupling (i-1) individual switched second observes the pixel of seeing image line, and determine subsequently one group to gray value that should a plurality of couplings prestore first observe the over sight (OS) light value, observe the over sight (OS) light value as i group first.That is, this first decision module 14 is found out the gray value of each pixel of first switched image line of a certain row that receive of coupling respectively, determine again to should gray value second observe the over sight (OS) light value and observe the over sight (OS) light value to form second of one group of next column.In like manner, this second decision module 15 is found out the gray value of each pixel of second switched image line of a certain row that receive of coupling respectively, determine again to should gray value first observe the over sight (OS) light value and observe the over sight (OS) light value to form first of one group of next column.
According to this preferred embodiments, these are a plurality of prestore second observe over sight (OS) light value and this a plurality of prestore first observe the over sight (OS) light value must be respectively with a left eye gray scale light leak brightness transition curve and a right eye gray scale light leak brightness transition curve representation, as shown in Figure 3A.See also Fig. 3 A and Fig. 3 B, Fig. 3 A is the gray scale light leak brightness transition curve of expression according to this preferred embodiment.Fig. 3 B is the gray scale light leak gradation conversion curve of expression according to this preferred embodiment.By a polarising glass and the plane of polarization plate module that cooperatively interacts, use measuring instrument to measure the images of left and right eyes gray value of this display floater 3 to light leak brightness transition curve, as shown in Figure 3A.Its metering system can be closed eye image information earlier, only stays left-eye image information, measures corresponding light leak brightness to set up the gray scale light leak brightness transition curve of this right eye from the right eye polarising glass again.In like manner, left-eye image information is closed, only stay eye image information, measure corresponding light leak brightness to set up the gray scale light leak brightness transition curve of this left eye from the left eye polarising glass again.Maximum brightness value among Fig. 2 B divided by 255, is regarded single gray scale intensities value.Again with the brightness of left eye light leak divided by single gray scale intensities, as left light leak gray value, with left eye gray scale light leak gradation conversion curve, shown in Fig. 3 B.In like manner, the brightness of right eye light leak divided by single gray scale intensities, is regarded right eye light leak gray value, to get right eye gray scale light leak gradation conversion curve, shown in Fig. 3 B.In addition, when because of bias light obvious light leak being arranged, then when calculating single gray scale intensities and light leak gray value, should in calculating, deduct as if panel itself.
Therefore, left eye light leak gray value among Fig. 3 B and right eye light leak gray value promptly be respectively this a plurality of prestore second observe over sight (OS) light value and this a plurality of prestore first observe the over sight (OS) light value.This first decision module 14 judges that switched first observes the pixel of seeing image line (that is right eye is watched image line) and mate which gray value, and determine one group of left eye light leak gray value according to the left eye gray scale light leak gradation conversion curve among Fig. 3 B, observe the over sight (OS) light value as second to gray value that should a plurality of couplings.In like manner, this second decision module 15 judges that adjusted second observes the pixel of seeing image line (that is left eye is watched image line) and mate which gray value, and determine one group of right eye light leak gray value according to the right eye gray scale light leak gradation conversion curve among Fig. 3 B, observe the over sight (OS) light value as first to gray value that should a plurality of couplings.
According to this preferred embodiment, this line register is electrically coupled to this selector 20.These line register 16 its respective outer side edges receive alternately and deposit that j group second is observed the over sight (OS) light value and i group first is observed the over sight (OS) light value.This distribution module 17 its respective outer side edges receive the j group second that is deposited in this line register 16 and observe the over sight (OS) light value and second observe the over sight (OS) light value to produce about what j second observed that the j group of seeing image line distributed.Or receiving the i group first be deposited in this line register observes the over sight (OS) light value and first observes the over sight (OS) light value to produce about what i first observed that the i group of seeing image line distributed.That is one group of light leak value that this distribution module 17 will be stored in this line register 16 forms one group of light leak value of having distributed with these a plurality of light leak values of weight allocation.As for 16 storages of this line register is first to observe over sight (OS) light value or second and observe the over sight (OS) light value by these selector 20 decisions, as previously mentioned.
