Preview is shown.
As the improvement of the technical scheme, the target area is the arbitrary region of the image of the collection.
As the improvement of the technical scheme, the target area scaling preview of the second camera is shown takes the photograph with described first
As the image of head is shown in same interface, and show can be positioned at the image of first camera for target area scaling preview
Optional position.
As the improvement of the technical scheme, after system receives the tactile according to target region of user, show and treat zoom area.
Further, it is described to treat that zoom area realizes amplification/diminution by touch-control.
Further, it is described to treat that zoom area carries out region amplification/diminution by double finger touch-controls.
Further, after target area, which is realized, to be scaled, the second camera, which starts and carries out image preview, to be shown.
On the other hand, the present invention also provides a kind of control system that image scaling is carried out based on dual camera, including：Micro- place
Manage device, the first camera and second camera；First camera and the second camera respectively with the microprocessor
Connection；
Wherein, first camera is used to perform collection image and image zooming function is realized；
The second camera is used to perform to be shown to zoom area.
Another further aspect, the present invention also provide a kind of control system that image scaling is carried out based on dual camera, including：
IMAQ and zoom control module, collection figure after enabled instruction is received for performing step the first camera
Picture, while zoom function switch is opened；
Zoomed image display module, for perform step system receive user input target area zoom request after,
The scaling preview of second camera progress target area is opened to show.
The beneficial effects of the invention are as follows：It is provided by the invention it is a kind of it is image local being zoomed in and out, Consumer's Experience is good
Control method and system that image scaling is carried out based on dual camera, solve user using during camera, work as needs
When being zoomed in or out to preview interface local message, it is not necessary to which panorama thing interface is zoomed in or out, and the area scaled is only needed to user
Domain zooms in or out.This programme can be in the case where not changing overall preview area, the region interested only to user
Or part zooms in and out.The program realizes quick flexible operating during on local region contracting-expanding, is brought more preferably to user
Usage experience.

Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.
The present invention provides a kind of control method that image scaling is carried out based on dual camera, comprises the following steps：
First camera gathers image after receiving enabled instruction, while zoom function switch is opened；
After system receives the target area zoom request of user's input, open second camera and carry out target area scaling
Preview is shown.
As an embodiment, this programme includes two functional modules：First, scale opening module；Second, zoom function is real
Existing module.Reference picture 1, it is the scaling opening module schematic flow sheet of first embodiment of the invention.After opening camera success, open
Zoom function sets switch；If scaling setup failed, return to scaling and open step；Set successfully, be then transferred to such as Fig. 2 when scaling
Shown zoom function realizes step；The picture preview interface first-class into camera or shooting, by pressing image zooming region
Certain point, provide zoom area, then provide target area by double finger scalings and zoom in or out, scale successfully, then start the
Two cameras, and scaling preview area is shown, scaling is completed.
Reference picture 3, the present invention provide a kind of control method that image scaling is carried out based on dual camera, including following step
Suddenly：
First camera gathers image after receiving enabled instruction, while zoom function switch is opened；
After system receives the target area zoom request of user's input, open second camera and carry out target area scaling
Preview is shown.
Wherein, local selection is carried out by the picture gathered to the first camera and scaled；Regional area can be first
Camera gathers any part of picture.
Selection region size, scaled by using double refer to, finger contract the area size of the circle that surrounds as scaling；
After selecting zoom area, second camera starts, and zoom area is focused and shown；
Wherein, the picture that second camera is shown, with the first camera picture on same LCD.And second camera
Picture, it can be slided on LCD, be moved to diverse location.
The second camera target area scaling preview show be shown in the image of first camera it is same
Interface, and target area scaling preview shows the optional position for the image that can be located at first camera.
After system receives the tactile according to target region of user, show and treat zoom area.Wherein, it is described to treat that zoom area passes through
Touch-control realizes amplification/diminution, it is preferred that described to treat that zoom area carries out region amplification/diminution by double finger touch-controls.Work as target area
After scaling is realized in domain, the second camera, which starts and carries out image preview, to be shown.
This programme example as shown in Figure 4, Figure 5, such as is gone window-shopping and sees clothes, wants to check on the information of label regional area 1, is led to
The selection that shooting photo carries out regional area 1 is crossed, is then amplified, and shows by second camera to obtain picture preview 2,
And then signage information is can clearly be seen, it is very convenient.
Likewise, when enjoying scenery, it can arbitrarily amplify local region of interest；Or in preview magazine, to certain part
Small character region carries out partial enlargement in order to check small character situation.
The present invention also provides a kind of control system that image scaling is carried out based on dual camera, including：Microprocessor, first
Camera and second camera；First camera and the second camera are connected with the microprocessor respectively；
Wherein, first camera is used for the realization for performing collection image and image scaling；
The second camera is used to perform to be shown to the zoom area.
Reference picture 6, the present invention also provide a kind of control system that image scaling is carried out based on dual camera, including：
IMAQ and zoom control module, collection figure after enabled instruction is received for performing step the first camera
Picture, while zoom function switch is opened；
Zoomed image display module, for perform step system receive user input target area zoom request after,
The scaling preview of second camera progress target area is opened to show.
It is provided by the invention it is a kind of it is image local being zoomed in and out, Consumer's Experience is good carries out figure based on dual camera
As the control method and system of scaling, solves user using during camera, when needing that preview interface local message is put
During big or diminution, it is not necessary to which panorama thing interface zooms in or out, and the region for only needing to scale to user zooms in or out.We
Case can be in the case where not changing overall preview area, and only to user, region interested or part zoom in and out.The program
Quick flexible operating during on local region contracting-expanding is realized, more preferable usage experience is brought to user.
Above is the preferable implementation to the present invention is illustrated, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent variations on the premise of without prejudice to spirit of the invention or replace
Change, these equivalent deformations or replacement are all contained in the application claim limited range.
