Description

A method for intelligent sleep of mobile phone

technical field

The invention relates to the technical field of mobile phones, in particular to a method for intelligent sleep of a mobile phone.

Background technique

Smartphones are increasingly integrating smart somatosensory functions, among which smart sleep is a typical one. The function of smart sleep is that when the screen is on, even if the user does not operate the mobile phone, the screen will not turn off as long as the eyes are on the screen when it is time to automatically turn off the screen. The principle is to use the human eye recognition of the camera. When the screen of the mobile phone is about to be turned off, the front camera is automatically turned on to detect whether there are human eyes to control the screen off.

However, due to the limited viewing angle and distance of the camera, this type of smart sleep is more likely to be unrecognizable, for example, when the mobile phone is far away from the eyes, or the eyes are not facing the camera.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a method for intelligent sleep of mobile phones.

The object of the present invention is achieved through the following technical solutions:

The method for smart sleep of the mobile phone of the present invention comprises the following steps:

S1. When the time to turn off the screen is up, the screen is not turned off immediately, but the camera is turned on and the timer T1 is started;

S2. Turn on the front camera, take pictures, and perform image analysis to identify human eyes to determine whether there are human eyes;

S3. If there are human eyes, then turn off the timer T1 and reset the screen-off time, and the screen remains on at this time;

S4. If there is no human eye, then start the gyroscope, read the data of the three axes of the gyroscope all the time within the timer T1 time, and judge whether the values of the three axes of x, y, and z are close to 0;

S5. If it is close to 0, it means that the mobile phone is in a static and non-operating state, then turn off the timer T1, and let the mobile phone enter the screen-off state at the same time. If one of the three axes is greater than the set maximum value, then it means this If the phone shakes, reset the screen-off time.

Preferably, the time set by the timer T1 is 8-15 seconds.

Preferably, in step S2, the method for image analysis is:

S21. Binarize the image;

S22. The mobile phone has a built-in binary feature library of various human eye images;

S23. Traverse the entire picture to check whether there are multiple feature combinations of human eyes, and if so, consider that the picture contains human eyes.

Preferably, in step S5, the set maximum value is 20 degrees per second.

Preferably, after step S5, re-execute steps S1-S5; when re-execute to step S5, if the state at this time is that the camera does not detect human eyes, and the mobile phone is still in a shaking state, then the screen is turned off.

Preferably, in step S5, the screen-off time is reset to 8-15 seconds.

Compared with the prior art, the present invention has the following advantages and effects:

1. After using the present invention, we can improve the current smart sleep and reduce the problem of non-recognition failure.

2. The present invention can more accurately detect whether the mobile phone really needs to be in the lighted state through the detection of human eyes.

Description of drawings

Fig. 1 is a flow chart of the present invention.

Detailed ways

The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

Example

As shown in Figure 1, a kind of method for smart sleep of mobile phone of the present invention comprises the following steps:

Step 1: When the time to turn off the screen is up, the screen is not turned off immediately, but the camera is turned on, and the timer T1 is started (for example, 10s).

Step 2: Turn on the front camera, take pictures, and analyze the image to identify human eyes to determine whether there are human eyes.

The specific steps for image analysis and human eye recognition are:

1. Perform binary processing on the image, that is, black and white processing, because when the human eye recognizes, only black and white pictures are needed;

2. The mobile phone has a built-in binary feature library of various human eye pictures;

3. Traverse the entire picture to check whether there are multiple feature combinations of human eyes. If there are, then it is considered that the picture contains human eyes.

Step 3: If there are human eyes, then turn off the timer T1 and reset the screen off time, and the screen will not go off naturally at this time.

Step 4: If there is no human eye, then start the gyroscope (the gyroscope is also called an angular velocity sensor, which can detect the angular velocity of the x, y, and z axes. When the mobile phone is stationary, the values of the three axes are close to 0. If the mobile phone is held in the hand, then the values of the three axes must not be close to 0), during the timeout period of the timer T1, keep reading the data of the three axes of the gyroscope, and judge the three axes of x, y, z Whether the value of each axis is close to 0.

Step 5: If it is close to 0, it means that the mobile phone is in a static and non-operating state, then turn off the timer T1, and let the mobile phone enter the screen-off state at the same time, if one of the three axes is greater than the set value, then it means that at this time If the mobile phone shakes, it is likely that the user is holding the mobile phone in his hand to read, then reset the screen-off time and perform step 1 again.

Step 6: When step 5 is executed again, the state at this time is that the camera does not detect human eyes, and the mobile phone is still in a shaking state. At this time, the screen is turned off to avoid the mobile phone being in a shaking environment for a long time, but The user does not consult the mobile phone for this situation.

Those of ordinary skill in the art can understand that all or part of the steps in the methods of the above-mentioned embodiments can be completed by instructing related hardware through a program, and the corresponding program can be stored in a computer-readable storage medium. Media, such as ROM/RAM, magnetic disk or optical disk, etc.

The above-mentioned embodiment is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited by the above-mentioned embodiment, and any other changes, modifications, substitutions, combinations, Simplifications should be equivalent replacement methods, and all are included in the protection scope of the present invention.
