Problems solved by technology

[0005] In addition, many games do not allow the screen to be turned off during runtime or during video playback
In this case, when the user encounters other things and forgets to turn off the mobile terminal or exit the game or video, it is also a waste of power

Embodiment 1

[0025] see figure 1 The standby method provided by Embodiment 1 of the present invention includes the following steps:

[0026] S101. Use the distance sensor to detect whether there is an obstacle in front of the screen. If there is an obstacle, execute S102. If not, execute S105;

[0027] In Embodiment 1 of the present invention, S101 may specifically be: detecting whether there is an obstacle in front of the screen through a distance sensor every preset time period.

[0028] In Embodiment 1 of the present invention, S101 may specifically include the following steps:

[0029] Detect whether the terminal screen is turned on;

[0030] If it is detected that the terminal screen is turned on, the distance sensor detects whether there is an obstacle in front of the screen every preset period of time.

[0031] In Embodiment 1 of the present invention, before S101, the method may further include the following steps:

[0032] It is judged whether the function of automatically tur...

Embodiment 2

[0044] see figure 2 , the standby system provided by Embodiment 2 of the present invention includes: a detection module 11, an acquisition module 12, a first judgment module 13 and a shutdown module 14, wherein,

[0045] The detection module 11 is used to detect whether there is an obstacle in front of the screen by a distance sensor;

[0046] Obtaining module 12, for if there is obstacle, then open camera to obtain the image of obstacle;

[0047] The first judging module 13, is used for judging whether to recognize the position of human face in the image of obstacle;

[0048] The closing module 14 is used to turn off the camera and the screen backlight and enter the standby state if no face is recognized in the image of the obstacle.

[0049] In the second embodiment of the present invention, the best part of the human face is the eyes, but it can also be the mouth, nose, forehead, etc. of course.

[0050] In the second embodiment of the present invention, the detection m...

Abstract

The invention belongs to the field of mobile terminals, and provides a standby method and system. The standby method comprises the steps that whether an obstacle exists in front of a screen or not is detected through a range sensor, a camera is started to acquire images of the obstacle if the obstacle exists, whether parts of a human face are recognized in the images of the obstacle or not is judged, and if the parts of the human face are not recognized in the images of the obstacle, the camera and a screen backlight are closed to enter a standby state. According to the standby method and system, the screen can turn black automatically when a user does not watch the screen, electric quantity can be saved, and standby time can be effectively prolonged. Furthermore, due to the fact that the camera is started to acquire the images of the obstacle only when the range sensor detects the existence of the obstacle in front of the screen, the time for starting the camera can be reduced to the maximum extent, and power consumption can be lowered.

Description

technical field [0001] The invention belongs to the field of mobile terminals, and in particular relates to a standby method and system. Background technique [0002] At present, in order to save limited power, mobile terminals have the function of automatically turning off the screen and then standby. The basic principle is: within the set time, if there is no button or touch screen event, the screen will be turned off and standby, otherwise, the timing will be restarted from the button or touch screen event. [0003] However, most of the time, the mobile terminal is in the pocket or bag. At this time, accidental key presses or screen touch events are likely to occur on the mobile terminal. This will cause the screen to stay on for a long time and fail to stand by, resulting in increased power consumption and wasted power. [0004] For example: after the user sets the dynamic wallpaper, he does not press the power button forcibly and puts it in his pocket. Unexpected key...
