Based on above-mentioned mobile terminal hardware configuration and the electrical structure schematic diagram of camera, image pickup method of the present invention is proposed each
Individual embodiment.
As shown in Fig. 2 the present embodiment provides a kind of image processing method, including：
Step S110：Response zoom operation, control collection module carries out Digital Zoom；
Step S120：Using the first image for becoming the defocused collection module collection first size；
Step S130：Cutting described first image, obtains the second image of the second size；Wherein, second size is little
In described first image；
Step S140：Show second image.
The present embodiment provides a kind of image processing method, can be applicable in the electronic equipment for include collection module, here
Collection module may include the structures such as camera or any one video camera existing shown in Fig. 1.
Zoom operation will be responded in step S110 in the present embodiment, and control collection membrane module carries out Digital Zoom.
For example, user touches touch screen by finger, is input into zoom operation to electronic equipment, withdraws defocused user's finger is become, generally
The shake of electronic equipment can be caused, say photographing unit for another example, user carries out zoom by the hardware configuration of rotating lens, works as user
After Departure operation, very maximum probability is also had the shake of handheld device occur.And the image that may result in collection is shaken because of shake
There are the image blur phenomena such as ghost image.
In the present embodiment in order to improve picture quality, for example, minimizing image blur phenomena, improving image definition,
Image acquisition can be carried out with larger first size when carrying out image acquisition, obtain the first image.Here first size can be
Number corresponding to unit pixel point.
The shake of usual electronic equipment, can cause acquisition module moving up and down in the perpendicular which is located,
Like this, the subregion in image can be made unsharp image quality issues such as fuzzy occur.
Electronic equipment is obtained less with respect to the first image in backstage, meeting cutting described first image in the present embodiment
Second image of size.For example, the first size includes S1 unit pixel；Second image may include S2 unit picture
Element；The S2 is less than the S1；And this S2 unit pixel is the partial pixel in the S1 unit pixel.Generally crop
S1-S2 pixel be to be unsatisfactory for the part of clear condition, like this, can be made by the image cropping on electronic equipment backstage
The image definition of display is higher, hence for stabilization process is achieved for user, improves the intelligent of electronic equipment,
During concrete implementation, methods described also includes to delete described first image and stores second image,
Facilitate access second image of subsequent user.
In certain embodiments, step S130 may include：
According to Pruning strategy, at least part of neighboring area of described first image is cropped, form second image.
It is previously stored with Pruning strategy in the present embodiment in the electronic equipment, or has reception to cut out from other electronic equipments
Cut strategy.Research finds, the image for gathering in electronic equipment dither process, and fuzzy region is usually located at the periphery of image.?
Main according to Pruning strategy in the present embodiment, the neighboring area of the first image is cropped, retains the mesozone of described first image
Domain, forms second image.
The left figure of Fig. 3 A is described first image, and the right figure of Fig. 3 A is second image, dotted line frame pair in the first image
The part that answers is the part of second image.Obviously cutting obtains the chi for being smaller in size than described first image of the second image
Very little, while zone line of second image for described first image.
The left figure of Fig. 3 B is described first image, and the right figure of Fig. 3 B is second image, dotted line frame pair in the first image
The part that answers is the part of second image.Obviously cutting obtains the chi for being smaller in size than described first image of the second image
Very little, while the second image includes the zone line of described first image and part of its periphery region.
In some embodiments, step S120 may include：
Using the defocused collection module is become, the first image that N opens the first size is gathered；Wherein, the N is not for
Integer less than 2；
Step S130 may include：
Compare N and described first image is opened, during cutting and retain the overlapping region that the N is opened in described first image, formed
Second image.
The collection module can gather multiple described first images before the second image of output in the present embodiment；Institute
The first image is stated for the collection image in electronic equipment dither process not in the same time.As electronic equipment is during shake,
The acquisition targets such as scenery, personage and/or the animal of collection module collection can be caused to change, and the region for changing first
Certainly it is neighboring area.As long as the jitter amplitude of the electronic equipment is not especially big, then two the first images have portion certainly
Divide acquisition target to be to maintain constant, and generally these acquisition targets are all the zone lines for being apparent in the first image, and logical
It is often all that clearly that is, the overlapping region is the zone line that the N opens the first image.In the present embodiment, in order to determine
The size of zone line is remained, opens the comparison of the first image in the present embodiment by N, select N and open the first image
Overlapping region retains as the zone line, generates second image.Obviously, the chi of second image for so being formed
The very little size for being clearly to be less than the first image.
In some embodiments, described second a size of becomes the picture size of defocused predetermined output；
Step S130 may include：
Select in described first image equal to second size zone line as reservation region, first described in cutting
Image, forms second image.
A picture size can be all corresponded to after Digital Zoom, and second size directly makes a reservation for for described in the present embodiment
Picture size.In the present embodiment in cutting, the central point with described first image is that the central point of the second image retains
The image-region of the second size, forms the second image.Being existed due to the generation for obscuring higher frequency time according to research as previously mentioned
Neighboring area, it is clear that can so lift the definition of the second image, lifts the picture quality of image.
In certain embodiments, step S130 may also include：
Obtain the definition of described first image regional；
Selecting definition the region for presetting definition condition to be met as reservation region, forms second image.
Can be multiple regions first by the first image division in the present embodiment；Various processing modes are recycled to obtain the
The definition of regional in one image.For example, using edge gradient detection, correlation detection and based on statistics and/or change
The evaluation function of change, detects the definition of regional.
Next the multiple regions for selecting definition higher more than predetermined threshold value or definition, used as the reserved area of cutting
Domain, forms second image.
Certainly, the method described in the present embodiment, occurs in the first figure according to the region maximum probability that statistical probability definition is low
The periphery of picture, therefore can also be formation based on image strategy second image in the present embodiment.Certainly, there is also this
May, when neighboring area also has part clear, reservation region described in the present embodiment can be not limited to zone line, this
Sample can obtain the second image of the size of maximum.
Specifically such as, step S130 may include：Described first image is divided into the region of N number of homalographic；Root again
According to the definition of described image, select M of continuous distribution the region for presetting definition condition to be met as reservation region, formed
Second image.The M is less than or equal to the N.For example, the N is equal to 16, the M and can be equal to 4.The M for remaining
Individual region can be zone line and/or the neighboring area in N number of region.
