In one embodiment, target movement can be the slide of the first finger on the screen, can also be second-hand
Refer to slide on the screen, target movement can also be the sliding behaviour of the first finger and second finger jointly on the screen
Make.
In the present embodiment, target movement includes that first object corresponding with first finger is mobile and with described the
The corresponding second target movement of two fingers；Step 120 includes：
Before first object movement, the first make contact of first finger on the screen is obtained；
Before second target movement, the second contact point of the second finger on the screen is obtained；
Based on the first make contact and second contact point, first finger and second finger are calculated on the screen
The first distance.
The present embodiment it is understood that target movement can only include the movement of corresponding with the first finger first object,
The movement of corresponding with second finger the second target can also be only included, target movement can also include corresponding with the first finger the
Mobile and corresponding with second finger the second target movement of one target.
It should be pointed out that user finger in contact screen, it is assumed that be the first finger first with screen contact, this
When, terminal can record the first finger and starting point when screen contact.When the first finger carries out first time sliding on the screen
When, terminal can record the first finger the first finger all in first time sliding process and after sliding and screen
Contact point.When the first finger carries out second on the screen to be slided, terminal can record the first finger and be slided for the second time
In journey and sliding after all the first fingers and screen contact point.
In the present embodiment, it is to be understood that when the first time sliding that first object movement is the first finger, then first
Contact point is above-mentioned starting point.When first object movement is second of sliding of second finger, then first make contact is first
The final contact point of first finger and screen after secondary sliding.And so on, first make contact can be the first finger
Before primary sliding, with starting point when screen contact；First make contact can be the first finger before n-th sliding, the
Contact point with screen after one finger is slided at the N-1 times.Based on this, first make contact can be understood as moving in first object
Before dynamic, when the first finger will execute first object movement, contact point that the first finger is formed on the screen.
It is furthermore appreciated that, after the first finger and screen contact, it is also necessary to second finger and screen contact.From
For the time sequencing of contact, the first finger and second finger can have certain tandem, also can simultaneously and screen contact.
Preferably, the present embodiment is first specifically addressed the present embodiment with screen contact with the first finger.When second finger and screen
After curtain contact, terminal can record second finger and starting point when screen contact.When second finger carries out first on the screen
When secondary sliding, terminal can record second finger second finger all in first time sliding process and after sliding with
The contact point of screen.When second finger carries out second on the screen to be slided, terminal can record second finger at second
In sliding process and sliding after all second fingers and screen contact point.
In the present embodiment, it is to be understood that when the first time sliding that the movement of the second target is second finger, then second
Contact point is above-mentioned starting point.When the movement of the second target is second of sliding of second finger, then the second contact point is first
The final contact point of second finger and screen after secondary sliding.And so on, the second contact point can be second finger
Before primary sliding, with starting point when screen contact；Second contact point can be second finger before n-th sliding, the
Contact point with screen after two fingers are slided at the N-1 times.Based on this, the second contact point can be understood as moving in the second target
Before dynamic, when second finger will execute second target movement, contact point that second finger is formed on the screen.
Further, it is based on the first make contact and second contact point, first finger and the can be calculated
The first distance of two fingers on the screen.Current embodiment require that, it is emphasized that first make contact and the second contact point in time
With corresponding correspondence, specifically, first make contact and the contact point that the second contact point is synchronization.
In the present embodiment, step 140 includes：
After first object movement, the third contact point of first finger on the screen is obtained；
After second target movement, the 4th contact point of the second finger on the screen is obtained；
Based on the third contact point and the 4th contact point, first finger and second finger are calculated on the screen
Second distance.
First finger can obtain the third contact point of the first finger and screen after carrying out first object movement.The
Two fingers can obtain the 4th contact point of second finger and screen after carrying out the second target movement.It is understood that
Third contact point and the 4th contact point can be the contact point of synchronization.
In the present embodiment, first make contact, the second contact point, third contact point and the 4th contact point can be finger and screen
Coordinate points when curtain contact on the screen.Based on these coordinate points, the first distance and second distance can be calculated.
In the present embodiment, step 160 includes：
When the second distance be less than described first apart from when, reduce the three-dimensional view angle；
When the second distance be more than described first apart from when, amplify the three-dimensional view angle.
When second distance be less than first apart from when, illustrate that the first finger is more and more closer at a distance from second finger, on the contrary, then
Illustrate that the two is more and more remoter.Range difference based on the two, the three-dimensional view angle for the camera that corresponding can zoom in or out.
In the present embodiment, step 160 includes：
Calculate absolute value of the difference between first distance and the second distance；
Based on the absolute value, corresponding scale value is determined；
Based on the scale value, scaling of corresponding size is carried out to the three-dimensional view angle.
Absolute value is the range difference of the first distance and second distance.Scale value can be the units that camera zooms in or out
Amount.Based on the range difference, corresponding function can be set, with the occurrence of control scaling.I.e. be based on absolute value, can be based on pair
The function answered calculates corresponding scale value, and scaling of corresponding size can be carried out to three-dimensional view angle based on the scale value.For example, the
The first distance between one finger and second finger can be 100 pixels, and second distance can be 120 pixels, since distance increases
Greatly, expression will amplify three-dimensional view angle.At this point it is possible to according to the distance between the first distance and second distance poor 20, camera
Distance furthers 20 units, to amplify three-dimensional view angle.
