It is described in further detail.
Fig. 2 is referred to, Fig. 2 is a kind of across the schematic flow sheet for shielding window display method for the embodiment of the present invention is provided, wherein,
The rear end equipment in screen window display method can apply to video monitoring system, as shown in Fig. 2 should be shown across screen window
Method can include：
Step 201, the length according to each screen for constituting video wall and the length and width for determining target sub-block wide；Wherein, each screen
Curtain can carry out decile according to the size of the target sub-block.
In the embodiment of the present invention, the border in each screen level direction in video wall is referred to as the length of screen, vertical direction
Border is referred to as width, and the present invention is subsequently no longer repeated.
In the embodiment of the present invention, for the position across screen window in each display screen for preferably determining to be shown in video wall
Put, it is necessary to each screen for ensureing composition video wall as far as possible such as is at the screen of size；When each screen of composition video wall is not to wait big
During small screen (i.e. video wall is formed by special-shaped screen splicing), decile can be carried out by each screen, each screen is divided
It is the size identical sub-block of respective numbers, so as to be virtually a number of size by the video wall of special-shaped screen splicing
The mosaic screen that identical sub-block is spliced.
Correspondingly, to achieve these goals, it is necessary to first determine sub-block (this of each screen energy decile of composition video wall
Referred to herein as target sub-block) size (long and wide), so as to the size according to the target sub-block will constitute each of video wall
Screen is divided into a number of size identical sub-block.
Used as a kind of optional implementation method, in above-mentioned steps 201, the length and width of each screen according to composition video wall are true
The length and width of the sub-block that sets the goal, including：
Carry out prime factor decomposition to the length and width of each screen respectively, and determine the first greatest common factor of the length of each screen with
And second greatest common factor wide of each screen；
The length and width of target sub-block are determined according to first greatest common factor and the second greatest common factor.
In this embodiment, in order to determine the length and width of target sub-block, can respectively to constituting each screen of video wall
Length and width carry out prime factor decomposition, and determine greatest common factor (the referred to herein as first most grand duke of the length of each screen respectively
Factor) and each screen greatest common factor (referred to herein as the second greatest common factor) wide.
As an example it is assumed that a length of 960 (pixels, similarly hereinafter) of screen A, a width of 800；A length of the 320 of screen B, it is a width of
640, then prime factor decomposition is carried out to the length and width respectively to screen A and screen B, respectively obtain：
Screen A is long：960=2x2x2x2x2x2x3x5
Screen B is long：320=2x2x2x2x2x2x5
Screen A is wide：800=2x2x2x2x2x5x5
Screen B is wide：640=2x2x2x2x2x2x2x5
And then, it can be deduced that, the greatest common factor of the length of screen A and screen B is 2x2x2x2x2x5=160；Screen A and
The greatest common factor wide of screen B is 2x2x2x2x2x5=160.
In this embodiment, it is determined that first greatest common factor and each screen of the length of each screen of composition video wall
The second greatest common factor wide after, target sub-block can be determined according to first greatest common factor and the second greatest common factor
Length and width.
For example, can directly using first greatest common factor as target sub-block length, and by second greatest common factor
As the width of target sub-block；Or, can using any prime factor of first greatest common factor as target sub-block length, and will
Any prime factor of the second greatest common factor as target sub-block width.
For example, still by taking above-mentioned example as an example, the maximum prime factor of the length of screen A and screen B is 160, target sub-block
Length can be 160,80,40 etc.；The maximum prime factor wide of screen A and screen B is 160, and the width of target sub-block can be
160th, 80,40 etc..
Preferably, in embodiments of the present invention, the greatest common factor (i.e. the of the length of each screen of video wall can be constituted
One greatest common factor) as the length of target sub-block；Greatest common factor (i.e. second maximum wide of each screen of video wall will be constituted
Common factor) as the width of target sub-block.
As another optional implementation method, in above-mentioned steps 201, the length and width of each screen according to composition video wall
Determine the length and width of target sub-block, including：
The minimum value of the length of each screen and the minimum value wide of each screen are determined respectively；
When the minimum value of the length of each screen can be divided exactly by the length of each screen, the minimum value of the length of each screen is defined as mesh
Mark the length of sub-block；Otherwise, the minimum value of the length of each screen is reduced according to default step-length, until the first value after reducing can be each
The length of screen divides exactly or the minimum value of length of each screen is reduced to 1, and first value or 1 are defined as the length of target sub-block；
When the minimum value wide of each screen can be divided exactly by the length of each screen, the minimum value of the length of each screen is defined as mesh
Mark the length of sub-block；Otherwise, the minimum value wide of each screen is reduced according to default step-length, until the second value after reducing can be each
The wide of screen is divided exactly or the minimum value wide of each screen is reduced to 1, and the second value or 1 are defined as the width of target sub-block.
In this embodiment, in order to determine the length and width of target sub-block, can first determine to constitute each screen of video wall
Length (or wide) minimum value, and judge whether the length (or wide) of each screen can be divided exactly by the length (or wide) of each screen, if so,
Then using the minimum value of the length of each screen as target sub-block length；Otherwise, each screen can be reduced according to default step-length (such as 1)
The minimum value of long (or wide), until the minimum value of the length (or wide) of each screen after reducing can be whole by the length (or wide) of each screen
Except or the minimum value of length (or wide) of each screen be reduced to 1.
Wherein, in embodiments of the present invention, by reduction after the first value can be referred to as by the value that the length of each screen divides exactly；To subtract
The value referred to as second value that can be divided exactly by the width of each screen after small.
As an example it is assumed that a length of the 800 of screen A, a length of the 640 of screen B, a length of the 160 of screen C, then screen A, B and
The minimum value of the length of C be 160, it can be divided exactly by the length of screen A, B and C, therefore, it can using 160 as target sub-block length.
Again as an example it is assumed that a length of the 800, a length of the 640 of screen B, a length of the 320 of screen C of screen A, then screen A, B
Minimum value with the length of C is 320, and it can not be divided exactly by the length of screen A, at this point it is possible to according to default step-length (assuming that step-length is 1)
The minimum value (i.e. 320) of the length of each screen is gradually reduced, when it is reduced to 160, it can be divided exactly by the length of screen A, B and C, because
This, can using 160 as target sub-block length.
Step 202, decile is carried out to each screen according to the length and width of target sub-block, and record sub-block and son that decile is obtained
The corresponding relation of the screen that block is belonged to.
In the embodiment of the present invention, when length and width that target sub-block is determined, can be according to the length of the target sub-block and width
Decile is carried out to each screen respectively, each screen for constituting video wall is divided into a number of size identical sub-block.
After completing partition, can record the screen that each sub-block and sub-block are belonged to corresponding relation (namely screen with
The corresponding relation of the sub-block that the screen includes).
As a kind of optional implementation method, in above-mentioned steps 202, the screen that the sub-block that record decile is obtained belongs to sub-block
The corresponding relation of curtain, can include：
The sub-block that position equity according to each sub-block in video wall is got is numbered；
The position of position, each screen according to each sub-block in video wall in video wall records the sub-block that each screen includes
Numbering.
In this embodiment, after the partition to each screen is completed, can be according to each sub-block in video wall
The sub-block got of position equity be numbered.
For example, can be according to video wall from left to right, order from top to bottom, respectively each sub-block be numbered,
The sub-block number in the most upper left corner is 1, and the numbering of the adjacent sub-block in sub-block the right is 2, sub-block number be 2 sub-block the right it is adjacent
The numbering of sub-block be 3 ....Assuming that video wall is divided into 10 rows 5 arrange, then the sub-block of the 1st row numbering from left to right is successively
It is 1,2 ..., 10；The sub-block of the 2nd row numbering from left to right is followed successively by 11,12 ..., 20.
Again for example, each sub-block can be numbered according to the row and column where each sub-block, the son of the row of the 1st row the 1st
The numbering of block is (1,1), and the numbering of the sub-block of the row of the 1st row the 2nd is (1,2) ..., and the numbering of the sub-block of M row Nth columns is (M, N)；
Wherein, M, N are the positive integer not less than 2.
In this embodiment, it is determined that after the numbering of each sub-block, position that can be according to each sub-block in video wall
And position of each screen in video wall, determine the numbering of the sub-block that each screen includes, and record the sub-block that each screen includes
Numbering.
What deserves to be explained is, 201~step 202 of above-mentioned steps need not simultaneously be performed both by display every time when window is shielded,
And can be performed or according to other tactful cycles when video wall is initialized and run or when the screen of composition video wall changes
Property or timing perform, it implements the embodiment of the present invention and does not repeat.
