Component, n are the width of color vector, and r is target diversity factor.Exemplary, color component can include red component, green component
And blue component, alternatively, color component can include grayscale value, blue component and green component.
Then, it is determined that theThe number of difference pixel region in row pixel region, it should be noted that difference pixel region
Domain isH-th of pixel region in row pixel region, and theThe corresponding figure of h-th of pixel region in row pixel region
As data and theThe target diversity factor of the corresponding image data of h-th of pixel region in row pixel region is more than diversity factor
Threshold value, 0≤h≤j finally, can be using the ratio of the number of difference pixel region and j as initial difference value.
When determining the form of initial pictures according to initial difference value in step 105, if initial difference value is more than default threshold
Value, the then form that can determine initial pictures A are the 3 dimensional format of upper and lower pattern.If the initial difference value is not more than default threshold
Value then needs to extract the image data of third target area G1 from the image data of initial pictures A and from the initial graph
As A image data in extract the 4th target area G2 image data.Then the image of third target area G1 can be determined
The auxiliary difference value of data and the image data of the 4th target area G2, and when difference value is assisted to be more than predetermined threshold value, determine
The form of initial pictures A is the 3 dimensional format of left and right pattern.If the initial difference value and the auxiliary difference value are no more than default
Threshold value, then the form that can determine initial pictures A is not 3 dimensional format, and the form of determining initial pictures A is two-dimentional lattice
Formula.
Fourth aspect, as in Figure 3-5, initial pictures A can be not only divided by default cut-off rule C it is equal in magnitude and
The first identical prime area D1 of shape and the second prime area D2, initial pictures A can also be divided into greatly by auxiliary partition line E
Small equal and identical shape the first auxiliary area F1 and the second auxiliary area F2, and the default cut-off rule C can be perpendicular to grid
Line scanning direction, auxiliary partition line E can be parallel to grid line scanning direction namely default cut-off rule C perpendicular to auxiliary partition line
E.First object region X1 is the subregion of the first prime area D1, and not equal to the first prime area D1, the second target area
X2 is the subregion of the second prime area D2, and not equal to the second prime area D2, first object region X2 and the second target area
Domain X2 is adjacent, and shapes and sizes all same.Third target area G1 is the subregion of the first auxiliary area F1, and not equal to the
One auxiliary area F1, the 4th target area G2 is the subregion of the second auxiliary area F2, and be not equal to the second auxiliary area F2, the

Incorporated by reference to Fig. 3-4 and Fig. 3-5, the initial pictures A in the embodiment of the present invention can be rectangular image, initial pictures A
I rows pixel region and j row pixel regions can be corresponded to, i and j are the even number more than 0, that is, using a certain display screen straight
When connecing the display initial pictures, which can be made of i rows pixel region and j row pixel regions.The embodiment of the present invention
In first object region X1 can correspond in j row pixel regionsRow pixel region, the second target area X2 can be right
Answer in j row pixel regionsRow pixel region；Third target area G1 can correspond in the i row pixel regions
Row pixel region, the 4th target area G2 can correspond in i row pixel regionsRow pixel region.
Further, the image data in first object region and the picture number of the second target area are determined at step 104
According to initial difference value when, can formula be determined according to diversity factor first, determineK-th of pixel region in row pixel region
The corresponding image data in domain and theThe target difference of the corresponding image data of k-th of pixel region in row pixel region
Degree, 1≤k≤i, diversity factor determine that formula is：(Uk-Vk)/2n=r, wherein, UkIt isK-th of pixel in row pixel region
The color component of the image data in region, VkIt isThe color of the image data of k-th of pixel region in row pixel region
Component, n are the width of color vector, and r is target diversity factor.
Then, it is determined that theThe number of difference pixel region in row pixel region, it should be noted that difference pixel region
Domain isH-th of pixel region in row pixel region, and theThe corresponding figure of h-th of pixel region in row pixel region
As data and theThe target diversity factor of the corresponding image data of h-th of pixel region in row pixel region is more than diversity factor

When determining the form of initial pictures according to initial difference value in step 105, if initial difference value is more than default threshold
Value, the then form that can determine initial pictures A are the 3 dimensional format of left and right pattern；If the initial difference value is not more than default threshold
Value then needs to extract the image data of third target area G1, third target area G1 from the image data of initial pictures A
For the subregion of the first auxiliary area F1, and not equal to the first auxiliary area F1.And from the image data of initial pictures A
The image data of the 4th target area G2 is extracted, the 4th target area G2 is the subregion of the second auxiliary area F2, and is not equal to
Second auxiliary area F2, third target area G2 is adjacent with the 4th target area G2, and shapes and sizes all same.It then can be with
Determine the auxiliary difference value of the image data of third target area G1 and the image data of the 4th target area G2, and poor in auxiliary
When different value is more than predetermined threshold value, the form for determining initial pictures A is the 3 dimensional format of upper and lower pattern.If the initial difference value and should
Assisting difference value, the form that can then determine initial pictures A is not 3 dimensional format, and determines that this is first no more than predetermined threshold value
The form of beginning image A is two-dimensional format.
5th aspect, can also first really after performing step 104 and initial difference value is determined namely in step 105
