When judge user be by actual key operation to adjust short focus when, obtain after user operates in entity key
Focal length.Wherein, gesture operation includes slide or pressing operation.
It should be noted that this step 403 carries out after focusing.
Step 404：Focal length change multiple according to acquisition, which is amplified the first shooting picture processing and shows, to be put
The second shooting picture after big processing.
Wherein, change multiple according to the focal length of acquisition and processing is amplified to the first shooting picture, including：
Prompting user carries out the position selection operation of display picture and obtains the position of the position selection operation of user；
Focal length according to acquisition is changed multiple and is put centered on the position of the position selection operation of the user obtained to described
First shooting picture carries out smooth enhanced processing.
It is the physical button focusing mode shown after the first shooting picture as shown in Fig. 5 (a), wherein 1X is expressed as 1 times of Jiao
Away from nX is expressed as n times of focal length, and wherein n is the positive integer more than 1.It is the hand shown after the first shooting picture as shown in Fig. 5 (b)
Gesture operates focusing mode, and the distance of the bar slided according to finger, changes corresponding focusing multiple.Wherein, Fig. 5 (a) and Fig. 5
(b) it is only demonstration focusing mode, is not intended to limit the present invention, in addition to the focussing process of above-mentioned Fig. 5 (a) and Fig. 5 (b),
It can also include other focusing modes.
Further, when the jitter value of the mobile terminal of acquisition is more than pre-set dithering threshold, this method is also wrapped
Include：Terminate this flow, call autofocus mode.
In the method for the present invention, by showing the first shooting picture and being shot according to the focal length change multiple of acquisition to first
Picture is amplified processing, realizes taking over seamlessly for picture, specifically avoid and is cut by the picture near focussing process
The phenomenon shaken when changing, enhances the experience sense of user.
It should be noted that herein, term " comprising ", "comprising" or its any other variant are intended to non-row
His property includes, so that process, method, article or device including a series of elements not only include those key elements, and
And other elements that are not explicitly listed are further included, or further include as this process, method, article or device institute inherently
