Carry, and save electricity.
The structure that Figure 16 is shown as the embodiment two of the screen rotation control method of second of embodiment of the application is shown
It is intended to, as illustrated, the position of the eyes in step S161, detection described image data.
Step S162, the position shape according to the eyes is in line.
Step S163, calculates the slope of the straight line, the positive apparent direction of the user is recognized according to this.
Step S164, judges whether the slope of the straight line changes, and when judged result is changes, is walked
Rapid S165, otherwise carries out step S161.
Step S165, calculates the change angle of the slope.
Step S166, judges whether the change angle of the slope exceeds the permissible range value, when angle is changed in judgement
During beyond the permissible range value, step S167 is carried out, step S161 is otherwise carried out.
Step S167, rotates the current picture display direction of the display screen, so that the display screen is current
Picture display direction and the positive apparent direction of the user be consistent.
In summary, the screen rotation control method of the application, by analyzing the positive apparent direction of user, is adjusted aobvious according to this
The picture display direction of display screen curtain, therefore, the application is adapted to user with various gesture operation electronic equipments, and protects all the time
Hold the positive apparent direction of user and the picture display direction of display screen is consistent, improve screen rotation in the prior art and control
The degree of accuracy it is not high the problem of, the use feeling of user can be lifted.
