Still command, picture size keeps constant in control current display interface.
If step S4, the inclination angular displacement are schemed beyond downward angular displacement threshold value is preset in control current display interface
Piece reduces.
It is similar to above-mentioned steps S3, the inclination angular displacement of acquisition is carried out with default downward angular displacement threshold value in this step
Relatively, if the inclination angular displacement for obtaining is more than downward angular displacement threshold value is preset, picture reduces in control current display interface.
In specific implementation process, when the inclination angular displacement is beyond default downward angular displacement threshold value, then central authorities are triggered
Processing it calls picture to reduce instruction, and picture reduces in control current display interface.
It is envisioned that also including step in step S4：
Step S42, when it is described inclination angular displacement without departing from preset downward angular displacement threshold value when, triggering central processing unit call picture
Still command, picture size keeps constant in control current display interface.
