In the embodiment of the present invention, can also be after left eye target image and right eye target image be obtained, by target image
In may there is crenellated phenomena region be set as default processing region.For example, obtaining left eye target image and right eye target
After image, it is determined that including text information, then text information will be included in left eye target image and right eye target image
Region is used as default processing region.Or, can also be using the pixel value of pixel region within a preset range as default place
Reason region.
Optionally, can also be using whole left eye target image as the default processing region in left eye target image, will be whole
Individual right eye target image as the default processing region in right eye target image.
Step 103：For each pixel in the default processing region, by pixel value and N number of presetted pixel value
The absolute value of difference is more than the pixel of threshold value as the first background pixel point between any one presetted pixel value, and will be described
Any one is pre- in and pixel value adjacent with the first background pixel point and N number of presetted pixel value in default processing region
If the absolute value of difference is less than or equal to the pixel of the threshold value as first object pixel between pixel value, and will be described
The transparency of first object pixel is changed to the first transparency, and N is positive integer；Or, in the default processing region
Each pixel, by the absolute value of difference between any one presetted pixel value in pixel value and N number of presetted pixel value
Less than or equal to the threshold value pixel as the second background pixel point, and by the default processing region with described second
Background pixel point is adjacent and absolute value of the difference between any one presetted pixel value in N number of presetted pixel value is more than institute
The pixel of threshold value is stated as the second target pixel points, and it is transparent that the transparency of second target pixel points is changed into second
Degree, pixel value are changed to the pixel value of the second background pixel point.
Said in principle, step 103, the edge of specific image content is actually found in default processing region, it is right
The edge is processed.In first way, first object pixel is the edge pixel point of specific image content, its picture
Element value for specific image content set in advance one of N number of pixel value or differ very little with this N number of pixel value, it is with first
Background pixel point is adjacent, and the first background pixel point is in non-particular image content, its pixel value and specific image set in advance
The N number of pixel value for holding differs greatly.And in the second way, the second background pixel point is the edge pixel of specific image content
Point, and the second target pixel points are the pixel of non-particular image content, it is adjacent with specific image content.
After finding the edge of specific image content, say and the edge is processed.The embodiment of the present invention is provided at two kinds
Reason mode, first, the transparency of the edge pixel point of specific image content is modified, second, will be with specific image content
The transparency and pixel value of the pixel of the adjacent non-particular image content of the pixel at edge are modified, so as to alleviate spy
The crenellated phenomena when edge for determining picture material shows, so that it is more preferable to obtain visual effect.
Step 104：According to the left eye target image and the right eye target image after the change transparency treatment
3D is carried out to show.
Method provided in an embodiment of the present invention, the method and device for providing according to embodiments of the present invention, by determining left eye
First object pixel is saturating in default processing region in target image and right eye target image, and the default processing region of change
Lightness, or change the transparency and pixel value of the second target pixel points, so that adjacent pixel in default processing region
Transition between point is more natural, the crenellated phenomena when edge for alleviating the picture material in default processing region shows, so that
Obtain visual effect more preferably, while method provided in an embodiment of the present invention is simpler, processing speed is fast, operates also easier.
Specifically, in step 103, if default processing region has text information, N number of presetted pixel value can be default
The corresponding pixel value of text information in processing region.
After default processing region is determined, it is possible to which default processing region is processed.In order to mitigate default place
The crenellated phenomena that picture material in reason region is produced when showing, the embodiment of the present invention can be by various implementations to default
Processing region is processed, and is detailed below.
The first possible implementation：
Each pixel in the default processing region of step one, traversal, for any one pixel, however, it is determined that a picture
The absolute value of difference is more than threshold value between any one presetted pixel value in the pixel value of vegetarian refreshments and N number of presetted pixel value, and should
In the pixel value of the adjacent pixel of pixel and N number of presetted pixel value between any one presetted pixel value difference absolute value
Less than or equal to threshold value, then using the pixel as the first background pixel point, using the adjacent pixel of the pixel as the first mesh
Mark pixel, and go to step 2；Otherwise travel through next pixel.
For example, each pixel can use tri- colors of R, G, B in left eye target image and right eye target image
Passage is represented.For example, at this point for any one pixel in default processing region, however, it is determined that the indigo plant of the pixel
The absolute value of difference is more than threshold between any one default blue channel color value in chrominance channel color value and N number of presetted pixel value
It is poor between any one default red channel color value in value, the red channel color value of the pixel and N number of presetted pixel value
The absolute value of value is more than threshold value, the green channel color value of the pixel and any one default green in N number of presetted pixel value
The absolute value of difference is more than threshold value between passage color value.Also, any one pixel adjacent for the pixel, if
Determine the blue channel color value and any one default blue channel color value in N number of presetted pixel value of the adjacent pixel
Between difference absolute value be less than or equal to threshold value, the red channel color value of the adjacent pixel and N number of presetted pixel value
In between any one default red channel color value difference absolute value less than or equal to threshold value, the adjacent pixel it is green
In chrominance channel color value and N number of presetted pixel value between any one default green channel color value difference absolute value be less than or
Equal to threshold value, then using the pixel as the first background pixel point, and the adjacent pixel is used as first object pixel.
It should be noted that in the embodiment of the present invention, for how to travel through each pixel in default processing region simultaneously
Do not limit, each pixel in default processing region can be traveled through by the way of transversal scanning or longitudinal scanning, also may be used
With using each pixel in the default processing region of other modes traversal.Meanwhile, in the embodiment of the present invention, threshold value can basis
Actual conditions determine.For example threshold value can take 0, or any one number between 10 to 0.
Step 2, will be adjacent with the first background pixel point in the default processing region and pixel value is N number of pre- with described
If the absolute value of difference is less than or equal to the first object pixel of the threshold value between any one presetted pixel value in pixel value
The transparency of point is changed to the first transparency.
It should be noted that the first object pixel adjacent with the first background pixel point, actually presets treatment
In region, be less than by the absolute value that pixel value is difference between any one presetted pixel value in N number of presetted pixel value or
The edge pixel point of the specific image content such as word constituted equal to all pixels point of the threshold value.First background pixel point
It is the pixel adjacent with the edge pixel point of the specific image content.
In the embodiment of the present invention, the first transparency can be more than the transparency and described first of the first background pixel point
Minimum value in the transparency of target pixel points and the transparency less than the first background pixel point and the first object picture
Maximum in the transparency of vegetarian refreshments.I.e. according to the first background pixel point to first object pixel to first object pixel phase
The order of the pixel of adjacent specific image content, transparency is incremented by or successively decreases.
For example, if the transparency of the first background pixel point is 0.5, the transparency of first object pixel is 0.8, this
When, the first transparency may be located at any one number between 0.5 to 0.8.
Optionally, the first transparency can also by other means be determined.Specifically, being directed to and the first background pixel point
Any one adjacent first object pixel, can determine the first transparency of first object pixel according to below equation：
Wherein,It is first transparency,It is the transparency of the first background pixel point,It is the first object picture
The transparency of vegetarian refreshments, K1More than 0 and less than 1.Optionally, K1It is 0.5.
For example, as shown in Fig. 2 being a kind of pixel relation schematic diagram provided in an embodiment of the present invention.In Fig. 2, as
Vegetarian refreshments 1, pixel 2, pixel 3, pixel 4, pixel 6, pixel 7, pixel 8, pixel 9 are 8 fields of pixel 5
Pixel, in the embodiment of the present invention, can using any pixel in 8 field pixels of pixel 5 as pixel 5 phase
Adjacent pixel.Meanwhile, pixel 2, pixel 4, pixel 6, pixel 8 are 4 field pixels of pixel 5, now also may be used
Using any pixel in the 4 field pixels by pixel 5 as the neighbor pixel of pixel 5.
That is, in the embodiment of the present invention, can be by least one of 8 field pixels of the first background pixel point
Pixel as the first background pixel point neighbor pixel, it is also possible to by 4 field pixels of the first background pixel point
At least one pixel as the first background pixel point neighbor pixel.
In such scheme, by the transparency by the adjacent first object pixel of the first background pixel point is changed, so that
So that specific image content and background image content are (in the image i.e. outside specific image content area in default processing region
Hold) transition between neighbor pixel is more natural, the crenellated phenomena when edge for alleviating target area shows, so as to be regarded
Feel that effect is more preferable.
Second possible implementation：
Step one, all pixels point traveled through in the default processing region, however, it is determined that a pixel value for pixel with
The absolute value of difference is less than or equal to threshold value, and the pixel between any one presetted pixel value in N number of presetted pixel value
The absolute value of difference is more than between any one presetted pixel value in the pixel value and N number of presetted pixel value of the adjacent pixel of point
Threshold value, then using the pixel as the second background pixel point, using the adjacent pixel of the pixel as the second target pixel points,
And go to step 2；Otherwise travel through next pixel.
Likewise, each pixel in default processing region can be traveled through by the way of transversal scanning or longitudinal scanning
Point, it would however also be possible to employ each pixel in the default processing region of other modes traversal.
Step 2, by it is adjacent with the second background pixel point in the default processing region and with N number of presetted pixel
In value between any one presetted pixel value difference absolute value more than the threshold value the second target pixel points transparency more
It is changed to the pixel value that the second transparency, pixel value are changed to the second background pixel point.
For any one second target pixel points in the pixel adjacent with the second background pixel point, by the second target
The pixel value of pixel is changed to the pixel value of the second background pixel point.
For example, each pixel can use tri- colors of R, G, B in left eye target image and right eye target image
Passage is represented.The blueness that the blue channel color value of second target pixel points is changed to the second background pixel point is led to
Road color value, the red channel that the red channel color value of second target pixel points is changed to the second background pixel point
Color value, the green channel face that the green channel color value of second target pixel points is changed to the second background pixel point
Colour.
It should be noted that if it is determined that in the pixel adjacent with the second background pixel point, the second target pixel points
Quantity is more than 0, then the second background pixel point can be defined as the edge pixel point of specific image content；Edge pixel point reality
It is on border small by the absolute value of difference between any one presetted pixel value in pixel value and N number of presetted pixel value
In or equal to the threshold value all pixels point constitute specific image content edge pixel.Second target pixel points are
The pixel adjacent with the edge pixel point of the specific image content.
In the embodiment of the present application, the second transparency can be more than the transparency and described second of the second background pixel point
Minimum value in the transparency of target pixel points and the transparency less than the second background pixel point and second target picture
Maximum in the transparency of vegetarian refreshments.
Optionally, the first transparency can also by other means be determined.Specifically, being directed to and the second background pixel point
The target pixel points of any one adjacent second, can also determine the second transparent of second target pixel points according to below equation
Degree：
Wherein,It is second transparency,It is the transparency of the second background pixel point,It is second target picture
The transparency of vegetarian refreshments, K2More than 0 and less than 1.Optionally, K2It is 0.5.
Likewise, can be using at least one pixel of 8 field pixels of the second background pixel point as second back of the body
The neighbor pixel of scene vegetarian refreshments, it is also possible to make at least one of 4 field pixels of the second background pixel point pixel
It is the neighbor pixel of the second background pixel point.
In such scheme, by changing the transparency of the second target pixel points and by the pixel value of the second target pixel points
The pixel value of the second background pixel point is changed to, so that specific image content and background image content in default processing region
