Mode selectes step S10, and to select a Fractionation regimen from least one Fractionation regimen, at least one Fractionation regimen includes extremely
A few fixed Fractionation regimen and/or automatic Fractionation regimen.But the present invention is not limited to this, for those skilled in the art
For, the sequencing in user operation process between step S10 and step S11 can be selected according to the use habit of user
It selects.Also, the mode can also be omitted in such a way that Fractionation regimen is defaulted in setting and select step, such as set default segmentation mould
Formula is automatic Fractionation regimen, as a result, then without carrying out model selection and can be divided automatically.
Further, according to the present invention in the virtual dividing image processing method of provided embodiment one, specifically,
It can also include a step as shown in Figure 1 before the segmentation step being split to the image of reading for carrying out step S13
Rapid S12 judges whether a selected Fractionation regimen is fixed Fractionation regimen.If a selected mode is fixed point
The fixed Fractionation regimen of mode is cut, then after carrying out single pass to multiple original copys and reading image, according to selected one
Fixed Fractionation regimen directly carries out the image segmentation of step S13 to the image of reading, obtains and corresponds with multiple above-mentioned original copys
Multiple subgraphs, user is simple and quick without carrying out extra setting under fixed Fractionation regimen.At this point, user exists
When multiple original copys are placed on scanning board, need according to a fixed Fractionation regimen that is selected or will selecting come
Multiple original copys are placed in the region of scanning board corresponding with the fixation Fractionation regimen, are avoided to the segmentation of image and multiple
Error caused by the actual placement of original copy is not inconsistent.
Wherein, if judging a selected mode in step S12 for fixed Fractionation regimen, in the image to reading
Being split (i.e. before step S13), further includes judging under selected fixation Fractionation regimen before processing, read image
In various pieces corresponding with the fixed mode whether there is image the step of.In this step, to every in multiple portions
Binary conversion treatment is carried out in a part；Ratio shared by black pixel in the pixel extracted is calculated for each part；And basis
The ratio judges in each part with the presence or absence of image.When the ratio of black pixel in the pixels sampled point extracted is less than setting
Threshold value when, then it is assumed that image is not present in the part, in the multiple subgraphs obtained after image dividing processing, does not deposit to this
In the corresponding subgraph in the part of image, the operation for no longer carrying out step S17-S19 as shown in fig. 1 can be defaulted, with
Avoid unnecessary operation or the wasting of resources.
Wherein, if a selected mode is automatic Fractionation regimen in step S12, one is being carried out to multiple original copys
Secondary scanning and after reading the step S11 of image, and before segmentation step S13, it further include the image automatic judging according to reading
The corresponding relationship of multiple subregions of multiple original copys and scanning board of breaking judges automatically step, and segmentation step S13 is according to automatic
The result of judgement carries out image segmentation to the image of reading, obtains and multiple above-mentioned original copys multiple subgraphs correspondingly.?
Under automatic Fractionation regimen, after multiple original copys are placed on scanning board by user, without paying close attention to the actual placement of image, grasp
Make more convenient.
Wherein, step is judged automatically include the following: carry out step S14 as shown in fig. 1 first, determine the image read
It is upper to whether there is image with the one-to-one multiple portions of multiple subregions respectively.The present embodiment is to each of multiple portions
Part carry out binary conversion treatment respectively, by the binary conversion treatment, the pixel in each part be divided into white pixel point with
Two kinds of black pixel；Further, ratio shared by black pixel in the pixel extracted is calculated for each part；With according to this ratio
Example judges in each part with the presence or absence of image.Wherein, when extracting a certain number of pixels from each part, setting starting
Point is (0,0), can extract the pixel of m the pixel of lateral separation n, longitudinal gap pixel as pixels sampled point, to institute
The ratio of black pixel in the pixels sampled point of extraction is judged, if the ratio is not less than threshold value, then it is assumed that deposit the part
In image, if the ratio is less than threshold value, then it is assumed that image is not present in the part.
After determining above-mentioned multiple portions with the presence or absence of image, step S15 as shown in fig. 1 is carried out, to multiple
Whether the adjacent part in part there is graph connectedness to be judged in boundary.In the present embodiment, in multiple portions
The adjacent part method that in boundary whether there is graph connectedness to be judged are as follows: the fictitious line between the adjacent part
The two sides in boundary line respectively take scheduled rectangular area, and carry out binary conversion treatment to the rectangular area taken, by the binaryzation
It handles, the pixel in each rectangular area is divided into two kinds of white pixel point and black pixel, further, calculates the picture of extraction
Ratio shared by black pixel in vegetarian refreshments judges that it whether there is black border line according to the ratio of black pixel, or taken
It whether there is image in rectangular area, if there are black border lines in the rectangular area taken, then it is assumed that the adjacent portions divide it
Between be not connected to；If image is not present in the rectangular area taken, then it is assumed that be not connected between the adjacent part；If taken
There are images in rectangular area, then it is assumed that is connected between the adjacent part.Wherein, when the black pixel in the rectangular area taken
Ratio not less than threshold value, (for example, in the present embodiment one, which can be any number, such as 10%, as long as can expire
Sufficient image needs), the black pixel on length or width direction is is uniformly distributed, and the black pixel in unit length
The density variation of point be no more than another threshold value (for example, in the present embodiment one, which can be any number, such as
20%, as long as can satisfy image needs) when, then it is assumed that there are black border lines in the rectangular area taken；When being taken
Rectangular area in the ratio of black pixel be less than threshold value, then it is assumed that there is no images inside the rectangular area that is taken；Work as institute
The ratio of black pixel in the rectangular area taken is not less than threshold value, and black border line is not present, then it is assumed that the square taken
There are images in shape region.
More specifically, it if two original copys being individually positioned in adjacent part are placed side by side, is spaced closely together or is overlapped,
A black line of demarcation can be then generated at the virtual boundary line of adjacent part after scanning.And two original copys place interval farther out
When, black line of demarcation will not be generated after scanning.In addition, can have pre- scale usually as the surrounding boundary of the papery data of original copy
Very little white space.Therefore, multiple in judgement in the virtual dividing image processing method of embodiment one provided by the present invention
Adjacent part in part is needing to judge graph connectedness in the deterministic process whether boundary has graph connectedness
Central boundary both sides respectively take the rectangular area of certain size according to the size of white space, and implement binaryzation to the region.?
To determining after the rectangular area binaryzation: if the black pixel density in the rectangular area is greater than predetermined threshold, and horizontal direction
Upper black pixel presentation is uniformly distributed, and black pixel density deviation is no more than another predetermined threshold in unit length, then judges two figures
There are black lines of demarcation as between, adhere to two subgraphs separately；If black pixel density is less than threshold value in above-mentioned rectangular area, or
Close to zero (being lower than 1%), then judges two images relatively far apart, adhere to two subgraphs separately.
Step S16 as shown in fig. 1 is finally carried out, multiple original copys and scanning are judged according to above-mentioned connectivity judging result
Corresponding relationship between multiple subregions of plate.In the above-mentioned one-to-one multiple portions of multiple subregions with scanning board, such as
There are have graph connectedness between the adjacent part of image for fruit, then it is assumed that the adjacent part belongs to a subgraph, and original copy is put
It is placed in adjacent subarea corresponding with the adjacent part domain of scanning board, i.e., without image dividing processing between the adjacent part；
If there is between the adjacent part of image do not have graph connectedness, then it is assumed that the adjacent part is not belonging to a subgraph,
Original copy is respectively placed in each sub-regions corresponding with the adjacent part of scanning board, i.e., needs to carry out image between the adjacent part
Dividing processing.
Wherein, one-to-one with multiple subregions respectively on the image that judgement is read in the method for the present embodiment
Multiple portions whether there is in the step S14 of image, when the ratio of black pixel in the pixels sampled point extracted is less than threshold value
When, then it is assumed that image is not present in the part, then not depositing in the multiple subgraphs obtained after image dividing processing to this
In the corresponding subgraph in the part of image, the operation of step after no longer carrying out can be defaulted, to avoid unnecessary operation
Step or the wasting of resources.
It further include that figure is carried out to multiple subgraphs after the image segmentation for carrying out step S13 in the method for the present embodiment
As the step S17 that boundary is corrected, i.e., when having black border line between the adjacent sub-images of multiple subgraphs, by black border
Line carries out removal procedure and improves the effect of image procossing to reduce image interference.
Next, in virtual dividing image processing method provided by the present invention, after to image segmentation, into step
The image of rapid S19 exports step, and the specific way of output can be exports multiple subgraphs to computer respectively, and by calculating
Machine carries out next processing；Or it exports to copy device or printing equipment, and according to pre-set duplicating/print parameters
