The present embodiment is introduced with a specific example below, wherein in this embodiment, as shown in Figure 2 a and 2 b,
The back side of mobile terminal is arranged in first touch area, and the center initial coordinate of the first touch area is (0,0), initial with center
For coordinate as starting point, the corresponding maximum moving distance of X-axis (horizontal axis) is A, and the corresponding maximum moving distance of Y-axis (longitudinal axis) is B, is taken the photograph
The default location of focus frame is (0,0) position shown in Fig. 2 b after starting as head, and with (0,0) position for starting point, focus frame is being schemed
As preview area X-axis (horizontal axis) on maximum moving distance be X, it is maximum mobile in the Y-axis (longitudinal axis) of image preview area
Distance is Y.It is equal with the sliding distance in the second touch area in the first touch area.If user needs focus frame
It is moved to target focusing position (X1, Y1) from center (0,0), it, can be by index finger in the first Touch Zone in user's one-handed performance
Domain (is mirror image since the back side is practical, when in terms of the back side, practical moving direction is also mirror according to the arrow direction movement in Fig. 2 a
As).
Finger slides in first touch area at the mobile terminal back side, the second Touch Zone corresponding to image preview area
Focus frame in domain follows the sliding of finger and moves.Wherein the determination of displacement information can there are many modes, below to pass through
The mode of coordinate determines that displacement information is illustrated.
As shown in Figure 3a and Figure 3b shows, when finger slides into (A2, B2) from (A0, B0), then finger is in the first touch area
The relative distance of interior sliding is (A2-A0, B2-B0)=(a1, b1), and abscissa has changed a1 in the X direction, in the Y direction
Ordinate has changed b1, can determine glide direction and sliding distance according to changes in coordinates.
Then the focus frame in the second touch area also slides respective distances according to corresponding direction, after focus frame sliding still
Target focusing position is not reached, user needs to continue to execute slide, but since finger will reach the first touch-control
The edge in region, therefore finger can lift, and after the first touch area detects that finger leaves, can detect again finger and exist
Sliding distance and direction on first touch area, for example the relative distance of second of sliding is (a2, b2), then moves twice
Relative distance is (a1+a2, b1+b2), then focus frame needs to be moved again according to (a2, b2), due to the initial position of focus frame
For coordinate origin, focus frame reaches new position (a1+a2, b1+b2) at this time, repeats above operation, focus frame is made to be moved to mesh
Until marking focusing position (a1+a2+a3+...., b1+b2+b3+....)=(X1, Y1).
In an alternative embodiment of the invention, sliding mapping relations are coordinate mapping relations；According to the first touch area and the
The sliding mapping relations of two touch areas obtain slide in the second touch area the step of corresponding slip information, packet
It includes：The first changes in coordinates information corresponding to slide at least once is obtained, and according to coordinate mapping relations, obtains at least one
A first changes in coordinates information the second changes in coordinates information corresponding in the second touch area.
When sliding mapping relations is coordinate mapping relations, then needs to obtain in the first touch area and slide at least once
The first corresponding changes in coordinates information of operation.The second coordinate is being determined according to the first changes in coordinates information of a slide
After change information, there is the case where focus frame can not being adjusted to target focusing position according only to one second changes in coordinates information,
Therefore it may need to obtain multiple second changes in coordinates information, then need to obtain at this time at least once the corresponding to slide
One changes in coordinates information.After obtaining at least one first changes in coordinates information corresponding to slide at least once, root
According to the coordinate mapping relations pre-established, at least one available corresponding second changes in coordinates information.
On the basis of above scheme, correspondingly, adjusting the position of the focus frame in image preview area according to slip information
The step of setting, including：The the first changes in coordinates information corresponding second for obtaining slide for the first time according to coordinate mapping relations is sat
After marking change information, the position of the focus frame in image preview area is adjusted according to the second changes in coordinates information；If when default
Slide is not received in long, then stops the position for adjusting focus frame；If continuing to slide in preset duration,
Corresponding second changes in coordinates of the first changes in coordinates information of the slide received after being obtained according to coordinate mapping relations
Information, and the position of focus frame is updated, until stopping adjusting the position of focus frame when not receiving slide in preset duration
It sets.
After obtaining the first changes in coordinates information corresponding to slide for the first time, it can be obtained according to coordinate mapping relations
Corresponding second changes in coordinates information is taken, after determining corresponding second changes in coordinates information, is believed according to the second changes in coordinates
It ceases and position adjusting is carried out to the focus frame in image preview area, if the first touch area is in preset duration after Primary regulation
It does not receive slide again inside, then can determine that focus frame reaches target focusing position.
If after Primary regulation the first touch area slide is had received in preset duration, need at this time
The first changes in coordinates information is determined in first touch area again, and obtains corresponding second coordinate according to coordinate mapping relations and becomes
Change information, according to the position of the second changes in coordinates information update focus frame.If after adjusting twice the first touch area exist
It still can receive slide in preset duration, then need to continue to execute determining first changes in coordinates information and the second changes in coordinates
Information, and the process being adjusted according to the second changes in coordinates information, until after adjusting several times in preset duration
It is not received by slide, can determine that focus frame reaches target focusing position at this time.If after adjusting twice first
Touch area does not receive slide again in preset duration, then can also determine that focus frame reaches target focusing position at this time
It sets.
It should be noted that each first changes in coordinates information can be equal, can not also wait, user can be according to reality
Border demand carries out corresponding slide in the first touch area.
It is determined as coordinate mapping relations by the way that mapping relations will be slided, it can be true according to the changes in coordinates information of slide
Focus frame is adjusted to target focusing position based on determining changes in coordinates information realization by the changes in coordinates information for determining focus frame,
It can guarantee the accuracy of focusing, and the second changes in coordinates information can be greater than the first changes in coordinates information and form corresponding pass
System, may be implemented to adjust biggish changes in coordinates in the second touch area by lesser slide, guarantees the behaviour of user
Make convenience, promotes operating efficiency.
