Distance, be a fixed value." ↑ " represents in the direction such as Fig. 3 of camera lens, in addition, by Mission Objective and game role position
The starting point of the line vector of connection moves to the center of circle 4, and primary vector 1, the vector 3 of secondary vector 2 and the 3rd represent Mission Objective respectively
Between game role position three kinds of lines vector situation in embodiments of the present invention, shadow region as shown in Figure 3
Domain is to be expressed as default angular range 6, also referred to as presets angular range 6.For example,
The current direction of camera lens is obtained, and judges whether line vector 7 is located at the default angular range represented by shadow region
It is interior, as illustrated, S vectors are line vector, judge whether the angle between camera lens and S vectors meets predetermined angle scope,
Whether the embodiment in figure is line vector in default angular range.As can be known from Figure, line vector S is not in default folder
In angular region, it is therefore desirable to the direction of rotating lens so that the angle between the direction and line vector S of adjustment rear lens is met
Default angular range, i.e. line vector S are in buffering area.
3rd vector in Fig. 3, where the line vector of game role and Mission Objective is the primary vector of diagram
During position, the angle of primary vector and camera lens between is calculated, judges that camera lens should right direction rotation, that is to say, that mirror
Head turns clockwise, and increases primary vector and the angle of camera lens direction, until rotating to primary vector and camera lens between
Angle value meet with preset angular range, to avoid game role from blocking Mission Objective.When game role and Mission Objective
When line is in the position shown in vector 2, judge that camera lens should be to anticlockwise, that is to say, that camera lens will carry out rotate counterclockwise,
Make vector 2 and the angle increase of camera lens direction, until angle value of the rotation to secondary vector and camera lens between is in and preset
In angular range.When the line of game role and Mission Objective is in the position shown in the 3rd vector, in default angle model
In enclosing, then camera lens need not be adjusted.In embodiments of the present invention, default angular range is set according to experience actual in gaming

Angle value, then judges whether camera lens is equal with the angle value chosen towards the angle between line vector；If the two is equal,
Camera lens need not be adjusted；If the two, camera lens is subjected to rotation adjustment until the two angle value is equal.For example, pre-
If angular range is 30 °~60 °, optimum angle value can be median, i.e., 45 °.Because when camera lens start rotation, by camera lens from
Rotated to outside default angular range in default angular range, if rotating to default angular range edge, then once trip
Programme mark produces small displacement, and camera lens may rotate out of default angular range again, rotation tune will be now carried out again
It is whole.And rotate to the centre of default angular range, i.e., in optimum angle value, then the left and right sides of camera lens has buffering range,
It is that user brings more preferable experience so as to reduce the frequency of rotation of lens.
It should be noted that in embodiments of the present invention, if camera lens is carried out into rotation until camera lens according to the method described above
When angle between line vector is optimum angle value, it is possible that due to mirror caused by the drastically change of line vector
There is situation about shaking in head.Therefore, in embodiments of the present invention, correspondingly it is provided with pre- in two default angular ranges, i.e. Fig. 3
If the region shown in angular range dash area.

In the case of trigger event is listened to, line vector is may determine that first whether in default angular range,
If it is judged that line vector is in default angular range, then may not necessarily rotating lens, or camera lens is finely adjusted,
Adjust to centre position of the line vector in default angular range.If it is judged that line vector is not in default angular range
When, then can rotating lens in the predetermined direction, until line vector is in default angular range.Predetermined direction includes suitable
Clockwise and counter clockwise direction, specifically rotate depending on minimum according to which direction anglec of rotation according to which direction.
Alternatively, in order to avoid causing the trickle shake of camera lens because of game role action displacement, during each camera lens adjustment,
Camera lens according to predetermined direction rotate until centre position of the line vector in default angular range.For example, such as
Two sides of the default angular range shown in Fig. 3 and the angle of X-axis be between 30 degree to 70 degree, at this point it is possible to by line vector
It is adjusted to 50 degree or so of position, can so avoid the shake of camera lens.
