It is to be realized by sliding finger on the touchscreen.Since the different glide directions of finger represent different zoom operations,
Before judging that user currently requires that the multiple of amplification is imaged, need to judge to be amplification or reduction operation.Specifically, in the present invention
In one embodiment, the multiple for judging that user currently requires imaging to amplify includes the following steps S1011 to step S1013:
S1011 judges that user currently requires imaging to be amplification or reduce.
As previously mentioned, the different glide directions representative of user's finger on the touchscreen is different zoom operations.At this
In inventive embodiments, judging that user currently requires imaging is that a kind of method amplified or reduced is:
S1 detects glide direction of the user's finger on the screen of the affiliated terminal of camera.
It specifically can be position of the record user's finger on the screen of the affiliated terminal of camera, determined according to positional relationship

Hoping for success seems amplification.
S3, if glide direction is central point of the finger close to the screen of the affiliated terminal of camera, it is determined that user currently wants
Hope for success seems to reduce.
It, can be by doing a definition in program, for example, for finger front and back twice in screen position in the embodiment of the present invention
It sets at a distance from center's point of screen, if being once less than at a distance from center's point of screen afterwards once in screen in screen position before regulation
It is amplification that user, which currently requires imaging, when position is at a distance from center's point of screen, then when detecting that glide direction is that finger leaves and takes the photograph
When the central point of the screen of the terminal as belonging to head, determining that user currently requires imaging is amplification.Conversely, for before and after finger two
It is secondary in screen position at a distance from center's point of screen, if regulation before be once greater than at a distance from screen position and center's point of screen after
It is to reduce that once when screen position is at a distance from center's point of screen, user, which currently requires imaging, then when detecting that glide direction is
When finger is close to the central point of the screen of the affiliated terminal of camera, determining that user currently requires imaging is to reduce.
S1012 calculates user's finger when executing amplifying operation and is taking the photograph if judging that user currently requires imaging is amplification
The screen sliding distance of the terminal as belonging to head.
S1013 is determined according to finger in the relationship of the screen sliding distance of the affiliated terminal of camera and imaging amplification factor
The multiple that user currently requires imaging to amplify.
For example, if finger is in the screen sliding distance of the affiliated terminal of camera and the corresponding relationship of imaging amplification factor are as follows:
If finger is in the screen sliding distance 0.1cm of the affiliated terminal of camera, it is 0.2 times that amplification factor, which is imaged, then is detecting use
Family finger determines the multiple that user currently requires imaging to amplify when the screen sliding distance of the affiliated terminal of camera is 0.1cm
It is 0.2 times.It is of course also possible to provide finger in the screen sliding distance of the affiliated terminal of camera and imaging amplification factor structure in advance
At some specific function, then, user's finger is being detected in the screen sliding distance of the affiliated terminal of camera, by this
The multiple that user currently requires imaging to amplify also can be obtained in variable of the distance as the function after input.
S102, the relationship of the multiple and multiple threshold value that currently require imaging to amplify according to user, enables different field angles and takes the photograph
As a camera in head is shot.

The angle that two edges of the maximum magnitude of camera lens are constituted.The size of field angle determines the field range of optical instrument, that is, regards
Rink corner is bigger, and the visual field is bigger, and optical power is with regard to smaller.Generally, target object is more than that this angle would not be received in mirror
In front.Generally, field angle is bigger, and focal length is shorter.
Any one camera, so-called digital zoom all has the upper limit, once the multiple of digital zoom or right
The multiple that the user answered currently requires imaging to amplify has been more than this upper limit, and image will become blurred.Of the invention real
It applies in example, a multiple threshold value can be set, it is relatively large which can be field angle in different field angle cameras
Amplification factor maximum value of the camera in imaging clearly, that is to say, that the multiple that user currently requires imaging to amplify is more than
This multiple threshold value, obtained photo are not clearly.
In an embodiment of the invention, different field angle cameras include the first camera and second camera, described
The field angle of first camera is greater than the field angle of the second camera, wherein currently requires imaging to amplify according to user
The relationship of multiple and multiple threshold value a, if camera for enabling in different field angle cameras carries out shooting and may is that user
It is required that the multiple of imaging amplification is not more than multiple threshold value, then enables the first camera and shot, if the user requires imaging
The multiple of amplification is greater than multiple threshold value, then enables second camera and shot, and herein, the field angle of the first camera is greater than the
The field angle of two cameras.
For example, it is assumed that multiple threshold value is 2 times, if user, which requires the multiple of imaging amplification to be 1 times, is not more than multiple threshold value,
Biggish first camera of field angle is then enabled, for example, the camera that field angle is 80 ° is shot；If user requires imaging
The multiple of amplification is 4 times and is greater than multiple threshold value, then enables the lesser second camera of field angle, for example, field angle is 40 °
Camera is shot.
Step S102 is shot after gained photo carries out digital zoom and is exported by S103.
From the exemplary method taken pictures using different field angle cameras of above-mentioned attached drawing 1 it is found that passing through institute with the prior art
The digital zoom of meaning is merely cut out to image and/or amplifies difference, and the present invention is currently to require to be imaged according to user
The multiple of amplification and the relationship of multiple threshold value, the camera enabled in different field angle cameras are shot, then again
Digital zoom is carried out to the photo of the shooting.Since the field angle of camera is different, obtained image definition is different, because
This, when being selected the camera of different perspectives to shoot to the difference of photo amplification factor according to user, photo image quality is preferable, can
To obtain the higher photo of quality.
