In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, the required accompanying drawing used in embodiment or description of the prior art will be briefly described below, apparently, drawings in the following description are only some embodiments of the present invention, for those of ordinary skill in the art, without having to pay creative labor, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is 3D image principle schematic diagrames；
Fig. 2 is the schematic diagram of device provided in an embodiment of the present invention；
Fig. 3 is the flow chart of method provided in an embodiment of the present invention.Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and Examples, the present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
For the ease of understanding the present invention, the principle first to 3D TVs is simply introduced here.
The principle of 3D images is human eye " vision displacement " effect.Two of people or so are mutually interposed between 6.5 cms（The distance is referred to as " pupil average headway "), it means that if watching same object, two eyes are watched respectively from the viewpoint of left and right two.Left eye will be seen that the centre or left side of object, and right eye then can be appreciated that the centre or right side of object.When two objects arrived soon are imaged on the retina, the image on left and right two sides altogether, will obtain last stereo perception.As shown in figure 1, wherein, the part shown in 11 is the image that left eye is seen, the part shown in 12 is the image that right eye is seen, the part shown in 13 has relief image for what is seen after being synthesized through brain.And this relief source of acquisition is exactly " vision displacement " effect.That is, human eye parallax is the objective physical phenomenon for belonging to depth information, the horizontal parallax of the right and left eyes generation of people, is the physiological foundation for producing stereoscopic vision.
3D camera chains possess two video cameras of autonomous working, between the two in the presence of certain offset deviation, and all fixations of holding position, are thus obtained with synchronization but slightly differentiated two image files of angle in whole process is shot.It can be seen that, things principle is the same to the operation principle of 3D camera chains soon with people in fact, and only what list lacked for shooting process is the part of last synthetic stereo image in the brain.
Two a series of paintings faces of returning are shot by twin camera, can be handled using various ways.For example, under a kind of mode, can be handled using frame sequential method.Principle is that two a series of paintings faces are entered into between-line spacing insertion, and image file is alternateed to obtain an image watched by left eye and right eye.In playing process, television set first has to carry out frame sequential method decoding to 3D images.So-called frame sequential method, it is meant that be parsed 3D image files, then two a series of paintings faces are split, allows left eye picture to enter left eye, allow right eye picture to enter right eye, and at this moment, two eyes are also equivalent to two video cameras, because the picture seen is the presence of trickle angle difference, therefore, also it can just be synthesized in human brain, obtain the 3D images with certain depth.This depth is referred to as the depth of field.
Or, under another way, twin camera shoots in the way of the two a series of paintings faces returned can also be placed by left and right or up and down and synthesized.For example, under the mode that left and right is placed, the corresponding left-eye image of same frame and eye image composition piece image（Such as, left-eye image is in left side, and eye image is on right side）, then the image after each synthesis is arranged according to frame sequential., it is necessary to which the left-eye image and eye image of each two field picture are decoded into the image of full width in playing process, display screen is output in the alternate mode of right and left eyes and shown.
In a word, due to there is certain parallax between right and left eyes image, so that human brain is after being synthesized, it is possible to obtain the image with certain Deep Canvas.In the prior art, the parallax of right and left eyes image is that two camera lenses worked simultaneously are obtained on 3D video cameras, that is, being shot by two or so camera lenses placed side by side from the angle of left and right two, obtains the image with certain parallax.3D television sets of the prior art directly parse right and left eyes image from 3D film sources, are respectively delivered to left eye or right eye when playing.It can be seen that, the parallax of right and left eyes image depends on the camera lens of left and right two of 3D video cameras in 3D film sources.
Certainly, no matter two a series of paintings faces are deposited in which way, flag bit can be all carried in image information, it is left-eye image or eye image respectively for indicating, so as to when playing, 3D television sets can identify left eye or right eye information accordingly, and then determine that image should be made to enter left eye or right eye.
The present inventor has found during the present invention is realized, why uncomfortable phenomenon such as a Pull can be produced when watching 3D TVs, it is because the parallax of the right and left eyes image in 3D film sources is too big or too small, so that the depth of field for the 3D pictures that spectators see is excessive or too small.Nominally, in right and left eyes image, the distance of the blunt parallax of left and right mesh should be less than the interval of pupil between the point of screen farthest, and the distance of object protrusion screen is less than the longitudinal length of screen in picture, if beyond these scopes, human eye will feel dizzy sensation.But, the parallax criterion disunity of current 3D film sources, on the other hand, the oculopupillary actual spacing of people vary with each individual, and may be slightly larger than 6.5 centimetres, it is also possible to less than the pupil average headway.These factors all to often result in the dizzy of beholder.Therefore, the embodiment of the present invention need solve the problem of be that, for film supplier provide 3D film sources, i.e., the right and left eyes image produced by 3D video cameras parallax in the presence of, how the depth of field of 3D picture is adjusted, to mitigate the uncomfortable sensation of spectators.
Embodiment one
Referring to Fig. 2, depth of field adjusting apparatus provided in an embodiment of the present invention is included with lower unit：
Image identification unit 201, for the left-eye image and eye image in identification source；
When implementing, image identification unit 201 can perform corresponding identification operation under the triggering of a variety of trigger conditions.For example, it can be indicated to trigger by the depth of field adjustment received, the depth of field adjustment indicate can user sent as desired by preset device, such as, the preset device can be conventional TV remote controller, the button of " depth of field regulation " can be increased on a remote control, include the regulation of " increase " and " reduction " both direction.So, when user feels to occur uncomfortable sensations such as dizziness, be exactly by by
Replace page（The 26th article of detailed rules and regulations)
The lower button, the instruction of depth of field adjustment is sent to television set.
Or, in actual applications, it can also be triggered by starting-up signal, i.e., it is automatic to carry out depth of field adjustment after user's start, untill being adjusted to certain designated state, or receive the instruction for stopping adjustment.It will not enumerate here on other triggering modes.
Here signal source can refer to 3D film sources.As it was noted above, can carry the right and left eyes Information sign position of image in 3D film sources, therefore, the image identification unit 201 of the embodiment of the present invention can also identify left-eye image and eye image according to the flag bit of image.Certainly, it is also possible if being identified right and left eyes image using other identification methods, do not limit here.
Graphics processing unit 202, for moving the left-eye image to the position set, the left-eye image is cut off in the pixel black surround that the opposite side of moving direction occurs, the size of the left-eye image after scaling shearing to former left-eye image；And/or, the mobile eye image to the position set cuts off the eye image in the pixel black surround that the opposite side of moving direction occurs, the size of the eye image after scaling shearing to former eye image；
During specific progress depth of field adjustment, the embodiment of the present invention is realized by mobile left-eye image and/or eye image, specifically, can move in the horizontal direction left-eye image and/or eye image, so that on the basis of the parallax that two images are produced in shooting process, by the change of two images distance in the horizontal direction, to increase or reduce parallax, and then the purpose of the adjustment depth of field is reached.It should be noted that, changed as the aim is that obtaining relative position of the left-eye image with eye image in the horizontal direction, therefore, in specific move, left-eye image can only be moved, either only move eye image or can simultaneously be moved with left-eye image and eye image.Can be that the left-eye image to the left or is moved right into the pixel of preset number；And/or, the eye image to the right or is moved left into the pixel of preset number.
Certainly, in the case of moving at the same time, left-eye image can be moved from eye image to different directions, for example, while left-eye image is moved to the left, eye image is moved right；In the case where being moved to identical direction, it should be ensured that both movements are not synchronous, if for example, left-eye image and eye image are moved to the left, the number of pixels moved should be different.
For example, in the case where indicating to be triggered by depth of field adjustment, depth of field adjustment indicates that the instruction of the increase depth of field can be included, and now, graphics processing unit 202 can include：
First movement subelement, the pixel for the left-eye image to be moved to the left to preset number；
And/or,
Second movement subelement, the pixel for preset number that the eye image moves right.
Or, depth of field adjustment indicates the instruction that can also include reducing the depth of field, and now, graphics processing unit 202 can include：
3rd movement subelement, the pixel for preset number that the left-eye image moves right；And/or,
4th movement subelement, the pixel for the eye image to be moved to the left to preset number.
For example, when receiving the instruction of the increase depth of field, left-eye image can be moved to the left to certain pixel, while eye image is moved right certain pixel, this can cause the parallax of right and left eyes image increase, and then the depth of field of the 3D pictures of synthesis is increased.
It should be noted that in actual application, it is the equal of, by image " a cutting " part, then to move again by program that left-eye image and/or eye image, which are moved,.For example, for certain width image is moved to the left into 5 pixels, being performed such during concrete operations：The width image is cut to the image of 5 pixels since Far Left, the image after cutting out then is moved to the left 5 pixels again.When the image carried out after this movement being output into display screen being shown, " black surround " of 5 pixels occurs on the right side of display screen, be the equal of that the images of 5 pixels of original image left edge is removed from display screen and gone, the wide black surround of 5 pixels together is left in the right hand edge of display screen.Obviously, if directly being shown, then the effect of viewing can be influenceed, therefore, in embodiments of the present invention, after being moved to right and left eyes image, the operation handled this black surround can also be included.
For example, after the corresponding image of the pixel of removal is dismissed, remaining image can be amplified to the size of original image, display screen is then output to again and is shown.So, the right hand edge for being equivalent to screen is still the content of mobile preceding display, and there is no black surround generation.
Equally, if necessary to which right eye signal pattern is moved into 5 pixels to the right, so the black surround of 5 pixels just occurs in the eye image left side, therefore, need to cut 5 pixels that the right removal is gone by program, then remaining image is amplified to the size of original image, thus equivalent to the left hand edge or original content of image, and without black surround.In a word, the right and left eyes image parallax after so handling is added, and all presence without black surround in right and left eyes image.
Image output unit 203, it is aobvious for the left-eye image and/or eye image after the scaling to be output to
Display screen is shown.
After handling right and left eyes image, it is possible to the image after processing is output into display screen and shown.Due to changing the parallax of right and left eyes image, therefore, seen by person is the 3D rendering after depth of field increase or reduction.
It should be noted that, the moving frame of signal source is constituted equivalent to by multiple image, indicated by the depth of field is adjusted come in the case of triggering depth of field adjustment, when the instruction of depth of field adjustment is received at certain moment, the corresponding right and left eyes image of image currently exported is moved, accordingly, the follow-up corresponding right and left eyes image of every two field picture also all carries out identical processing.Certainly, after a depth of field adjustment, if user still feels under the weather, the adjustment of the depth of field is can also continue to be increased or reduces, untill feeling no longer dizziness.
Wherein, can be with pre-set, for example, the number of pixels once moved can be set on mobile number of pixels, that is, the step value adjusted.Assuming that the step value is 2 pixels, then often once increased the adjustment of the depth of field, left-eye image is moved to the left 2 pixels, eye image moves right 2 pixels；If carrying out the adjustment of the increase depth of field again on this basis, then left-eye image is moved to the left 2 pixels, eye image moves right 2 pixels；When receiving the instruction for reducing the depth of field, then left-eye image is moved right 2 pixels, eye image is moved to the left 2 pixels, by that analogy.
Certainly, the depth of field unrestrictedly can not increase or reduce, and otherwise may be such that 3D effect is not normal.Therefore, under the preferred embodiment of the present invention, a mobile max pixel value can also be set.So, before certain depth of field adjustment is carried out, it may determine that whether the sum of all pixels that the left-eye image and/or eye image have been moved to certain direction has reached preset maximum, if not up to described maximum, then continue to move to the direction, otherwise, no longer moved to the direction, or prompt message can also be provided.For example, assuming that the step value of adjustment is 2 pixels, the maximum of adjustment is 10 pixels, then after the adjustment that user sends the increase depth of field for continuous 5 times is indicated, if receiving the instruction of the increase depth of field again, then no longer it is adjusted correspondingly, while user can also be pointed out to attempt to adjust the depth of field in the opposite direction.
Wherein, it is determined that the movement max pixel value when, can be determined according to factors such as the actual size of television set, resolution ratio and the intervals that should be nominally less than pupil apart from farthest distance of the point in right and left eyes image of screen.For example, as mentioned before, nominally, in order to avoid producing dizzy sensation, distance of the point in right and left eyes image apart from screen farthest should be then caused to be less than the interval of pupil, accordingly, pupil average headway can be multiplied by preset adjustment ratio as the largest interval of adjustment.For example, adjustment ratio can be taken as 10%.That is, when pupil average headway is taken as 6.5 centimetres, adjustment is most
Large-spacing is no more than 6.5 millimeters.Under this condition, H does not have television set to be 55 cun, and screen width is about 1218 millimeters, and horizontal pixel is 1920, so, and the width of one pixel of correspondence is：1218/1920=0.634 millimeter, therefore, the corresponding pixel count of above-mentioned largest interval is 6.5/0.634-10 pixel.That is, such 10 pixels of left and right adjustment, equivalent to moving left and right 6.5mm, you can to cause the parallax of right and left eyes image to increase or reduce 6.5mm.
As can be seen here, when only left-eye image or eye image are moved to the left or to the right, the pixel maximum of the preset number is：Pupil average headway is multiplied by preset adjustment ratio, with product divided by screen width and the horizontal total pixel number purpose ratio of gained, the integer of the business of its gained is taken.
When left-eye image is moved to the left or to the right, while eye image is to the right or when being moved to the left, the pixel value of the left eye movement preset number and the pixel sum maximum of right eye movement preset number are：Pupil average headway is multiplied by preset adjustment ratio, with product divided by screen width and the horizontal total pixel number purpose ratio of gained, the integer of the business of its gained is taken.
In a word, the embodiment of the present invention is by handling 3D film sources, the parallax produced when alloing right and left eyes image not to shoot is played out, but can be adjusted according to the need for user, so as to solve because the image parallactic in film source is excessive or too small, the caused 3D pictures depth of field is excessive or too small, the problem of spectators are dizzy caused by entering.Simultaneously as being handled the black surround produced in image moving process, it therefore, it can further improve the play quality of 3D TVs.
Embodiment two
Corresponding with depth of field adjusting apparatus provided in an embodiment of the present invention, the embodiment of the present invention additionally provides one kind

Namely, this 3D television sets can be with the left-eye image and eye image in identification source, the position that the mobile left-eye image is extremely set, the left-eye image is cut off in the pixel black surround that the opposite side of moving direction occurs, the left-eye image after shearing is scaled to the size of former left-eye image, and/or the position that the mobile eye image is extremely set；The eye image is cut off in the pixel black surround that the opposite side of moving direction occurs, the size of the eye image after scaling shearing to former eye image；Then the left-eye image and/or eye image after the scaling are output into display screen to show.So, it is equivalent to defeated through this 3D tv display screens
The image gone out is the image for carrying out depth of field adjustment, for the parallax that this image is produced when shooting, further increase or reduce parallax, the depth of field is increased or is reduced accordingly, black surround will not be also produced simultaneously, the quality of television image is conducive to provide.
Wherein, changed as the aim is that obtaining relative position of the left-eye image with eye image in the horizontal direction, therefore, in specific move, left-eye image can be only moved, eye image is either only moved or can simultaneously be moved with left-eye image and eye image.Can be that the left-eye image to the left or is moved right into the pixel of preset number；And/or, the eye image to the right or is moved left into the pixel of preset number.Certainly, in the case of moving at the same time, left-eye image can be moved from eye image to different directions, for example, while left-eye image is moved to the left, eye image is moved right；In the case where being moved to identical direction, it should be ensured that both movements are not synchronous, if for example, left-eye image and eye image are moved to the left, the number of pixels moved should be different.
In actual applications, the depth of field unrestrictedly can not increase or reduce, and otherwise may be such that 3D effect is not normal.Therefore, under the preferred embodiment of the present invention, a mobile max pixel value can also be set.So, before certain depth of field adjustment is carried out, it may determine that whether the sum of all pixels that the left-eye image and/or eye image have been moved to certain direction has reached preset maximum, if not up to described maximum, then continue to move to the direction, otherwise, no longer moved to the direction, or prompt message can also be provided.
Specifically, when only left-eye image or eye image are moved to the left or to the right, the pixel maximum of the preset number is：Pupil average headway is multiplied by preset adjustment ratio, with product divided by screen width and the horizontal total pixel number purpose ratio of gained, the integer of the business of its gained is taken.When left-eye image is moved to the left or to the right, while eye image is to the right or when being moved to the left, the pixel value of the left eye movement preset number and the pixel sum maximum of right eye movement preset number are：Pupil average headway is multiplied by preset adjustment ratio, with product divided by screen width and the horizontal total pixel number purpose ratio of gained, the integer of the business of its gained is taken.
In a word, the embodiment of the present invention two in TV pusher side by handling 3D film sources, the parallax produced when alloing right and left eyes image not to shoot is played out, but can be adjusted according to the need for user, so as to solve because the image parallactic in film source is excessive or too small, the caused 3D pictures depth of field is excessive or too small, the problem of spectators are dizzy caused by entering.Simultaneously as being handled the black surround produced in image moving process, it therefore, it can further improve the play quality of 3D TVs.
