The preferable target of visual effect can be more comprehensively determined in image to be processed by different modes of composition
Position, for user selection target position it is more, electronic equipment is more intelligent, and the image-capable of electronic equipment compared with
By force.
Below to several possible modes of composition, and according to mode of composition determine the method for at least one target position into
Row explanation.
The first mode of composition:
Optionally, according to the trichotomy mode of composition of image to be processed, at least one target position is determined, comprising:
The length for obtaining image to be processed determines the 3-point line position of image to be processed in the longitudinal direction based on length；
And

The intersection point for determining the 3-point line position on length direction and the 3-point line position in width direction is at least one mesh
Cursor position.
As shown in Fig. 2, on the length direction of image to be processed, by lines L3 and lines L4 by image averaging to be processed
Ground is divided into three equal parts, and lines L3 and the position where lines L4 are the two 3-point line positions of image to be processed in the longitudinal direction
It sets.Similarly, in the width direction of image to be processed, image averaging to be processed is divided by lines L1 and lines L2 third
Part, then the position where lines L1 and lines L2 is the two 3-point line positions of image to be processed in the direction of the width.It is logical
Four intersection positions can be determined in image to be processed by crossing lines L1, lines L2, lines L3 and lines L4, then can incite somebody to action
Part intersection point in this four intersection points or the position where the intersection point of whole are determined as at least one of embodiment of the present invention
Target position.
Usually in composition, the 3-point line that main body outstanding emphatically will be needed to be placed on image in an image can choose
Intersection position on, preferable visual effect can be obtained in this way.Therefore, by trichotomy mode of composition, vision can be determined
The preferable target position of effect, the image-capable of better user experience, electronic equipment are stronger.
Second of mode of composition:
At least one target position can be determined by the diagonal line mode of composition of image to be processed.For example, can be first
Two of image to be processed or wherein a diagonal line are obtained, where partly or completely point that will be included on diagonal line
Position be determined as at least one target position.
In general, will be needed in an image emphatically main body outstanding be placed on the diagonal line of whole image, can effectively benefit
The sight of viewer is significantly guided into main body with the cornerwise length of picture, and visual effect is preferable, therefore, will be on diagonal line
Point is determined as the mode of at least one target position, can obtain the preferable target position of appreciation effect, for a user, vision
Experience preferably, while also improving the image-capable of electronic equipment.
The third mode of composition:
Optionally, at least one target position is determined, comprising:
It is closed according to the position of the 4th subgraph in image to be processed and the position of the 4th subgraph and the first subgraph
System, determines at least one target position.
In practical applications, for it is some include multiple main objects image, for example, two people group photo photo,
User may want to further the distance of two people, then can according to where one of people position and two people scheming
Positional relationship as in determines at least one target position.
For example, as shown in figure 3, including two subgraphs in image to be processed: the such as image of the little girl comprising the left side
The subgraph of information can be the 4th subgraph, and the subgraph of the image information of the spadger comprising the right can be the first subgraph
Picture.As can be seen that spadger and little girl's distance are farther out, user may wish to further the distance of the two, then can be with
Between subgraph in the image information of the little girl comprising the left side and the image information of the spadger comprising the right and distance
The closer place in position where the subgraph of the image information of little girl comprising the left side determines lines L5, can be by lines L5
The position at place is determined as at least one target position, or can also will be where all or part of point included by lines L5
Position is determined as at least one target position.In this way, can more easily will be in image to be processed between different subgraphs
Distance is furthered or is put far, and the image-capable of better user experience, electronic equipment is stronger.
In practical applications, mode of composition can there are many kinds of, cannot be illustrated one by one, it is above only to several compositions
As long as mode for example, can determine that the mode of composition of target position all covers of the invention from image to be processed
In protection scope.
Optionally, first object position may be the position where a point, since the first subgraph may be by very much
The image of a point composition, makes then the first subgraph can be moved by the central point of the first subgraph and first object position pair
The point answered is overlapped, or can also determine a point at random by electronic equipment in the first subgraph, so that the point after movement
It corresponding with first object position can put and be overlapped, or the position of a point can also be selected in the first image by user,
Enable after movement the position of the point it is corresponding with first object position point be overlapped, etc., the embodiment of the present invention to this not
It limits.For example, continuing with referring to fig. 2, for example the position of point A is first object position, the corresponding figure of the bird in the lower right corner
As being the first subgraph, user can choose determination, and the point B point A corresponding with first object position at bird eyes is heavy
It closes.
Alternatively, first object position is also possible to be the position where a line, make then the first subgraph can be moved
The center line of first subgraph is overlapped with first object position, or a line can also be determined in the first subgraph, so that
The lines after movement can line corresponding with first object position be overlapped, in this case, determined in the first image
Lines can be to be determined at random by electronic equipment, can also be selected by user determining, etc..The embodiment of the present invention does not limit this
It is fixed.Position for example, continuing with referring to fig. 2, such as where lines L4 is first object position, and the bird in the lower right corner is corresponding
Image is the first subgraph, can determine lines L0 and the first mesh included in the corresponding image of bird at random by electronic equipment
The corresponding lines L4 of cursor position is overlapped.
Optionally, before the first subgraph is moved to first object position, further includes:
Determine the boundary of the first subgraph；
First subgraph is moved to first object position, comprising:
It keeps the first subgraph constant, stretched through the image of opposite side out-of-bounds and/or is compressed so that the first subgraph
It is moved to first object position.
The boundary of first subgraph can be the edge wheel profile of the first subgraph, can by edge detection or its
The method of his image procossing obtains.Alternatively, the boundary of the first subgraph is also possible to one comprising including the first subgraph
Fixed shape, for example, can be the frame, etc. of the ellipse external with the first subgraph.The embodiment of the present invention is for first
The method of determination on the boundary of subgraph is not construed as limiting.
After the boundary that the first subgraph has been determined, the first subgraph can be moved, mobile mode can
To be: keep the first subgraph constant, that is, keep the Aspect Ratio of part in the boundary of the first subgraph, area and
The parameters such as pixel value do not change, are then stretched and/or are compressed through the part outside the boundary to the first subgraph, in turn
First subgraph is moved to first object position.In this way, the ratio that the first subgraph will not be changed, after processing
Image it is more true to nature, user's visual experience is preferable, and the image-capable of electronic equipment is stronger.
Optionally, it is stretched and is compressed so that the first subgraph is moved to first object position by the image of opposite side out-of-bounds
It sets, comprising:
According to position and first object position of first subgraph in image to be processed, include from image to be processed
The second subgraph and third subgraph are determined in the subgraph outside boundary；Wherein, the second subgraph is the shifting of the first subgraph
Subgraph pointed by dynamic direction, third subgraph are subgraph pointed by the opposite direction in the mobile direction of the first subgraph
Picture；
By compressing the second subgraph, and stretching third subgraph, so that the first subgraph is moved to first object position.
Second subgraph can be subgraph pointed by the direction that the first subgraph to be moved, for the second subgraph
Which parts of images pointed by the direction to be moved of specially the first subgraph, the embodiment of the present invention are not construed as limiting.For example,
It is in image to be processed, the first subgraph is mobile toward the left side, then whole or the portion on the first subgraph left side can will be located at
Partial image is as the second subgraph；Such as in image to be processed, the first subgraph is up moved, then can be with
All or part of image above the first subgraph will be located at as the second subgraph.
For compressing the mode of the second subgraph, the embodiment of the present invention is not construed as limiting, to be compressed in the horizontal direction
For, several possible modes are illustrated below:
The spacing between each column pixel can equidistantly be reduced, for example, can according to need compression length, with
And the columns of the pixel for the subgraph to be compressed, calculate the value that reduced spacing is needed between each column pixel.For example, will
1 centimetre of compression of images, include 200 column pixels on the image to be compressed, then can calculate needs between each column pixel
Reduce 0.05 millimeter of spacing, therefore the spacing between every two column pixel is reduced 0.05 millimeter just can be by compression of images
1 centimetre.
Alternatively, can be in such a way that pixel be deleted, for example, can detecte multiple row picture adjacent in the image for needing to compress
The variation of color between vegetarian refreshments, if there is there is color change between several column pixels less even without color change, then
One or more columns per page pixel can be deleted in this several column pixel, if the columns length in total for the pixel deleted with want
The equal length of compression.
It can also be above using the identical mode compressed with horizontal direction likewise, being compressed in vertical direction
Mode be that the method for compression is illustrated, can be compressed using one such mode in practical application,
Various ways can be integrated to be compressed, the embodiment of the present invention is not construed as limiting.
Third subgraph can be subgraph pointed by the opposite direction in the direction that the first subgraph to be moved, for
Three subgraphs are specially which parts of images, the embodiment of the present invention pointed by the opposite direction in the direction to be moved of the first subgraph
It is not construed as limiting.For example, in image to be processed, the first subgraph is mobile toward the left side, then the first subgraph can will be located at
As all or part of image on the right is as the second subgraph；It is such as in image to be processed, the first subgraph is past
Upper movement, then all or part of image below the first subgraph can will be located at as the second subgraph.
For stretching the mode of third subgraph, the embodiment of the present invention is not construed as limiting, equally to carry out in the horizontal direction
For stretching, several possible modes are illustrated below:
The spacing between each column pixel can equidistantly be increased, for example, can according to need stretching length, with
And the columns of the pixel for the subgraph to be stretched, calculate the value for the spacing for needing to increase between each column pixel.For example, will
1 centimetre of image stretch, include 200 column pixels on the image of Yao Lashen, then can calculate needs between each column pixel
0.05 millimeter of spacing is increased, therefore the spacing between every two column pixel is increased 0.05 millimeter.
Alternatively, can be in such a way that pixel be filled up, for example, can detecte every two column adjacent in the image for needing to stretch
The variation of color between pixel can be at this if two column pixel color changes are less even without color change
The pixel that increase by one arranges between two column pixels or several column colors are same or similar, if same or similar with two column colors
Pixel is one group, then only pixel can be increased in one group of pixel wherein, it can also be respectively in multiple groups pixel
Inside increase pixel, as long as the length that the columns of increased pixel adds up and the equal length to be stretched.
It can also be above using the identical mode stretched with horizontal direction likewise, being stretched in vertical direction
Mode be that the method for stretching is illustrated, can be stretched using one such mode in practical application,
Various ways can be integrated to be stretched, the embodiment of the present invention is not construed as limiting.
For example, as shown in figure 3, the subgraph of the image information of the spadger comprising the right can be the first subgraph, line
Position where L5 can be first object position.The subgraph of the image information of spadger comprising the right is moved to
On position where lines L5, then the complete of the subgraph left side of the image information positioned at the spadger comprising the right can be determined
Portion's subgraph is the second subgraph, or can also determine the subgraph and packet of the image information positioned at the spadger comprising the right
Parts of images between the subgraph of the image information of little girl containing the left side is second subgraph, etc..Wherein, third subgraph
As can be the image on the right of the subgraph of the image information of the spadger comprising the right.By being carried out to the second subgraph
Compression, and third subgraph is stretched, it just can be realized and the corresponding subgraph of spadger be moved to where lines L5
Position on.
