Step 103:, will be in pixel value and N number of presetted pixel value for each pixel in the default processing region
The absolute value of difference is greater than the pixel of threshold value as the first background pixel point between any one presetted pixel value, and will be described
And pixel value adjacent with first background pixel point and any one in N number of presetted pixel value are pre- in default processing region
If between pixel value the absolute value of difference be less than or equal to the threshold value pixel as first object pixel, and will described in
The transparency of first object pixel is changed to the first transparency, and N is positive integer；Alternatively, in the default processing region
Each pixel, by pixel value and N number of presetted pixel value between any one presetted pixel value difference absolute 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 greater 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 to second
Degree, pixel value are changed to the pixel value of second background pixel point.
It is said in principle, step 103, the edge of specific image content is actually found in default processing region, it is right
The edge is handled.In first way, first object pixel is the edge pixel point of specific image content, picture
Element value is one of N number of pixel value of preset specific image content or differs very little with this N number of pixel value, with first
Background pixel point is adjacent, and the first background pixel point is non-particular image content, in pixel value and preset specific image
The N number of pixel value held 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.
Behind the edge for finding specific image content, says and the edge is handled.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, to alleviate spy
The crenellated phenomena when edge display of picture material is determined, so that it is more preferable to obtain visual effect.
Step 104: according to the change transparency treated the left eye target image and the right eye target image
Carry out 3D display.
Method provided in an embodiment of the present invention, the method and device provided according to embodiments of the present invention, by determining left eye
Default processing region in target image and right eye target image, and change the saturating of first object pixel in default processing region
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, alleviates the crenellated phenomena when edge display of the picture material in default processing region, thus
It is more preferable to obtain visual effect, while method provided in an embodiment of the present invention is simpler, processing speed is fast, operates also easier.
Specifically, in step 103, presetting processing region, text information, N number of presetted pixel value can be default if it exists
The corresponding pixel value of text information in processing region.
After determining default processing region, so that it may handle default processing region.In order to mitigate default place
The crenellated phenomena that picture material in reason region generates when showing, the embodiment of the present invention can be by a variety of implementations to default
Processing region is handled, and is detailed below.
The first possible implementation:
Step 1: each pixel in default processing region is traversed, for any one pixel, however, it is determined that a picture
The absolute value of difference is greater 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
Pixel is marked, and goes to step 2；Otherwise next pixel is traversed.
For example, each pixel can use tri- colors of R, G, B in left eye target image and right eye target image
Channel indicates.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 that any one in chrominance channel color value and N number of presetted pixel value presets difference between blue channel color value is greater than threshold
It is poor between the default red channel color value of any one in value, the red channel color value of the pixel and N number of presetted pixel value
The absolute value of value is greater than the default green of any one in threshold value, the green channel color value of the pixel and N number of presetted pixel value
The absolute value of difference is greater than threshold value between the color value of channel.Also, for any one pixel adjacent with the pixel, if
Determine the default blue channel color value of any one in the blue channel color value and N number of presetted pixel value of the adjacent pixel
Between difference absolute value be less than or equal to threshold value, the adjacent pixel red channel color value and N number of presetted pixel value
In between any one default red channel color value absolute value of difference be less than or equal to threshold value, the adjacent pixel it is green
Any one in chrominance channel color value and N number of presetted pixel value preset green channel color value between 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 as first object pixel.
It should be noted that in the embodiment of the present invention, for how to traverse each pixel in default processing region simultaneously
It does not limit, each pixel in default processing region can be traversed by the way of transversal scanning or longitudinal scanning, it can also
To traverse each pixel in default processing region using other modes.Meanwhile in the embodiment of the present invention, threshold value can basis
Actual conditions determine.Such as threshold value can take 0, or any one number between 10 to 0.
Step 2: by the default processing region with first background pixel point adjacent and pixel value with it is described N number of pre-
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 default processing
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
Equal to the edge pixel point for the specific image content such as text that all pixels point of the threshold value is constituted.First background pixel point
For 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 greater than the transparency and described first of first background pixel point
Minimum value in the transparency of target pixel points and transparency and the first object picture less than first background pixel point
Maximum value 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 sequence of the pixel of adjacent specific image content, transparency is increasing or decreasing.
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 can any one number between 0.5 to 0.8.
Optionally, the first transparency can also be determined by other means.Specifically, being directed to and first background pixel point
Any one adjacent first object pixel can determine the first transparency of first object pixel according to the following formula:
Wherein,For first transparency,For the transparency of first background pixel point,For the first object
The transparency of pixel, K1Greater 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 8,8 fields that pixel 9 is pixel 5
Pixel can be using any pixel in 8 field pixels of pixel 5 as the phase of pixel 5 in the embodiment of the present invention
Adjacent pixel.Meanwhile pixel 2, pixel 4, pixel 6, pixel 8 are 4 field pixels of pixel 5, at this time 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, it can be by least one of the 8 field pixels of the first background pixel point
Neighbor pixel of the pixel as first background pixel point, can also will be in 4 field pixels of the first background pixel point
Neighbor pixel of at least one pixel as first background pixel point.
In above scheme, by the way that the transparency of the adjacent first object pixel of the first background pixel point will be changed, thus
So that specific image content and background image content are (in the image i.e. except specific image content area in default processing region
Hold) transition between neighbor pixel is more natural, the crenellated phenomena when edge display of target area is alleviated, to be regarded
Feel that effect is more preferable.
Second of possible implementation:
Step 1: all pixels point in the traversal default processing region, however, it is determined that the pixel value of a 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 greater than between any one presetted pixel value in the pixel value of the adjacent pixel of point and N number of presetted pixel value
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 next pixel is traversed.
Likewise, each pixel in default processing region can be traversed by the way of transversal scanning or longitudinal scanning
Point can also traverse each pixel in default processing region using other modes.
Step 2: by it is adjacent with second background pixel point in the default processing region and with N number of presetted pixel
The absolute value of difference is greater than the transparency of the second target pixel points of the threshold value more between any one presetted pixel value in value
It is changed to the second transparency, pixel value is changed to the pixel value of second background pixel point.
For any one second target pixel points in the pixel adjacent with second background pixel point, by the second target
The pixel value of pixel is changed to the pixel value of 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
Channel indicates.The blue that the blue channel color value of second target pixel points is changed to 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 second background pixel point
Color value, the green channel face that the green channel color value of second target pixel points is changed to second background pixel point
Color value.
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 greater than 0, then second background pixel point can be determined as to the edge pixel point of specific image content；Edge pixel point is real
It is on border by the absolute value of difference is small 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 greater than the transparency and described second of second background pixel point
Minimum value in the transparency of target pixel points and the transparency and second target picture less than second background pixel point
Maximum value in the transparency of vegetarian refreshments.
Optionally, the first transparency can also be determined by other means.Specifically, being directed to and second background pixel point
Second target pixel points of any one adjacent can also determine that the second of second target pixel points is transparent according to the following formula
Degree:
Wherein,For second transparency,For the transparency of second background pixel point,For second mesh
Mark the transparency of pixel, K2Greater 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
The neighbor pixel of scene vegetarian refreshments can also make at least one pixel in 4 field pixels of the second background pixel point
For the neighbor pixel of second background pixel point.
In above scheme, by changing the transparency of the second target pixel points and by the pixel value of the second target pixel points
It is changed to the pixel value of the second background pixel point, so that specific image content and background image content in default processing region
Neighbor pixel between transition it is more natural, alleviate specific image content edge display when crenellated phenomena, to obtain
Obtain better visual effect.
It should be noted that by taking specific image content is text as an example, it can also be according to default place in the embodiment of the present invention
The font attribute of text information, which is determined, in reason region still uses second of possible reality using the first possible implementation
Existing mode handles default processing region.
Specifically, if it is determined that the font size of text information is less than or equal to default font size in default processing region, then using the
A kind of possible default processing region of implementation processing；If it is determined that the font size of text information is greater than default in default processing region
Font size and be overstriking font, then handle default processing region using the first possible implementation；If it is determined that default treatment region
The font size of text information is greater than default font size and is not overstriking font in domain, then using second of possible implementation processing
Default processing region.
Finally at step 104, directly according to treated left eye target image and treated right eye target image into
Row 3D display.
It for example, is the figure without the embodiment of the present invention as shown in Fig. 3 (a) by taking specific image content is text as an example
The picture of 3D rendering as shown in after processing method processing.The sawtooth at text edge is obvious in Fig. 3 (a).Such as Fig. 3 (b) institute
Show, for the picture of the 3D rendering shown after image processing method provided in an embodiment of the present invention processing.In Fig. 3 (b), according to
After the embodiment of the present invention handles the picture, text edge becomes rounder and more smooth, has effectively eliminated the sawtooth at edge.
Again for example, as shown in Fig. 4 (a), for what is shown after the image processing method processing without the embodiment of the present invention
The picture of 3D rendering.The sawtooth at text edge is obvious in Fig. 4 (a).As shown in Fig. 4 (b), to be mentioned by the embodiment of the present invention
The picture of the 3D rendering shown after the image processing method processing of confession.In Fig. 4 (b), according to embodiments of the present invention to the picture into
After row processing, text edge becomes rounder and more smooth, has effectively eliminated the sawtooth at edge.
Below by the process of specific embodiment detailed description.
As shown in figure 5, being a kind of image processing method flow diagram provided in an embodiment of the present invention.
Step 301: left eye target image and right eye target image are obtained by Photo Browser.
Step 302: determining default processing region in left eye target image and right eye target image respectively.
