[0042] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0043] In a first aspect, the present invention provides a method for determining whether to turn on the screen based on the face ratio, referring to Figure 1 ,include:

[0044] S10, controlling the camera to lock the face and collect the face image;

[0045] S20, receiving a face image captured by a camera, analyzing the face image, and outputting a face direction and a face ratio value;

[0046] S30, judging the face direction and face ratio, when the face direction is correct and the face ratio is higher than a preset value, unlocking the screen; when the face direction is wrong or the face ratio is lower than a preset value, locking the screen and putting it to sleep.

[0047] It should be noted that the camera in this embodiment is set to a rotatable mode and can rotate along with the user to lock the face so as to capture the face image.

[0048] Reference Figure 2 In step S10: controlling the camera to lock the face and collect the face image, including:

[0049] S11, controlling the camera to rotate and capture a face image;

[0050] When the user's face is facing the screen, the camera rotates to face the face, captures the face, and obtains a face image.

[0051] S12, acquiring and storing a face image. The acquired face image is stored in a database to facilitate subsequent identification of the user.

[0052] Reference Figure 3 In step S20, a face image captured by a camera is received, the face image is analyzed, and a face direction and a face ratio value are output, including:

[0053] S21, identifying facial information and determining that the facial information is of a correct user; this step is to determine that the facial image captured by the camera is a facial recognition user in order to proceed to the next step of operation.

[0054] S22, output the face direction, calculate the ratio of the face to the screen and output it. The face direction in the face image captured by the camera may not be positive. This step is to analyze the face direction to ensure that the face direction is positive, so as to determine the face ratio. The face ratio is obtained by calculating the ratio of the face to the screen.

[0055] Reference Figure 4 In step S30, the face direction and the face ratio are determined. When the face direction is correct and the face ratio is higher than a preset value, the screen is unlocked; when the face direction is wrong or the face ratio is lower than a preset value, the screen is locked and put to sleep, including:

[0056] S31. If the face direction is determined to be positive, then the face ratio value is determined. When the face direction in the face image captured by the camera is positive, the subsequent determination of the face ratio value is meaningful, so as to ensure that the user wants to unlock the screen at this time.

[0057] Reference Figure 5 In step S31, if the face direction is determined to be positive, the face ratio is determined, including:

[0058] S311. When the face ratio is higher than a preset value, the screen is unlocked; wherein the preset value is that the face ratio to the screen ratio is 70%-100%. When the face ratio is higher than the preset value, it can be seen that most of the face is within the acquisition range of the camera. In this case, the screen is unlocked to speed up the wake-up of the device and improve the user experience.

[0059] S312: When the face ratio is lower than a preset value, the screen is locked and the screen is put into sleep mode. When the face ratio is lower than a preset value, that is, the face is not mostly within the camera's acquisition range, the user does not necessarily need to unlock the screen, so the screen is locked and the screen is put into sleep mode.

[0060] S32: If the face direction is determined to be non-positive, the screen is locked and put into sleep mode. When the face direction in the face image captured by the camera is non-positive, it means that the user does not want to unlock the phone, so the screen is locked and put into sleep mode to reduce the power consumption of the device.

[0061] Second, refer to Figure 6 An embodiment of the present invention provides a system for determining whether to turn on the screen based on the face ratio, including:

[0062] The camera acquisition and information storage module 10 is used to control the camera to lock the face and acquire the face image;

[0063] The analysis and processing module 20 is used to receive the face image captured by the camera, analyze the face image, and output the face direction and face ratio value;

[0064] The judgment output module 30 is used to judge the face direction and the face ratio. When the face direction is correct and the face ratio is higher than the preset value, the screen is unlocked; when the face direction is wrong or the face ratio is lower than the preset value, the screen is locked and put to sleep.

[0065] Specifically, the camera acquisition and information storage module 10 includes an acquisition unit 11 and a storage unit 12, wherein the acquisition unit 11 is used to control the camera to lock the face and acquire the face image, and the storage unit 12 is used to store the face image;

[0066] The analysis and processing module 20 includes an analysis unit 21 and a first output unit 22, wherein the analysis unit 21 is used to receive a face image captured by a camera and analyze the face image, and the first output unit 22 is used to output a face direction and a face ratio value;

[0067] The judgment output module 30 includes a judgment unit 31 and a second output unit 32. The judgment unit 31 is used to judge the face direction and the face ratio value. The second output unit 32 is used to unlock the screen when the face direction is correct and the face ratio value is higher than a preset value; when the face direction is incorrect or the face ratio value is lower than a preset value, the screen is locked and put to sleep.

[0068] Thirdly, refer to Figure 7 An embodiment of the present invention provides an electronic device 100, including a processor 110 and a storage 120, on which executable code is stored. When the executable code is executed by the processor, the processor executes a method as described above for determining whether to turn on the screen based on the proportion of a face.

[0069] The processor may be composed of a single packaged integrated circuit or a plurality of packaged integrated circuits with the same or different functions, including one or more central processing units (CPUs), microprocessors, digital processing chips, graphics processors, and a combination of various control chips. The processor is the control core (Control Unit) of an electronic device, which uses various interfaces and lines to connect the various components of the entire electronic device, and executes various functions of the electronic device and processes data by running or executing programs or modules stored in the memory, and calling data stored in the memory.

[0070] Among them, the memory may include various types of storage units, such as system memory, read-only memory (ROM) and permanent storage devices. Among them, ROM can store static data or instructions required by the processor or other modules of the computer. The permanent storage device may be a readable and writable storage device. The permanent storage device may be a non-volatile storage device that does not lose the stored instructions and data even after the computer is powered off. For example, the permanent storage device uses a large-capacity storage device (such as a magnetic or optical disk, flash memory) as a permanent storage device. For another example, the permanent storage device may be a removable storage device (such as a floppy disk, an optical drive). The system memory may be a readable and writable storage device or a volatile readable and writable storage device, such as a dynamic random access memory. The system memory may store some or all instructions and data required by the processor at run time. In addition, the memory may include any combination of computer-readable storage media, including various types of semiconductor storage chips (such as DRAM, SRAM, SDRAM, flash memory, programmable read-only memory), and disks and / or optical disks may also be used. In some embodiments, the memory may include a readable and / or writable removable storage device, such as a laser disc (CD), a read-only digital versatile disc (e.g., DVD-ROM, double-layer DVD-ROM), a read-only Blu-ray disc, an ultra-density optical disc, a flash memory card (e.g., SD card, mini SD card, Micro-SD card, etc.), a magnetic floppy disk, etc. The computer-readable storage medium does not include carrier waves and transient electronic signals transmitted wirelessly or wired.

[0071] A storage medium stores executable code thereon. When the executable code is executed by a processor of an electronic device, the processor executes a method as described above for determining whether to turn on the screen based on the proportion of a face.

[0072] The present invention provides a method for judging whether to turn on the screen by using the face ratio, which comprises controlling a camera to lock the face and collect a face image; receiving the face image collected by the camera, analyzing the face image, and outputting the face direction and the face ratio value; judging the face direction and the face ratio value, and unlocking the screen when the face direction is correct and the face ratio value is higher than a preset value; and locking and putting the screen to sleep when the face direction is wrong or the face ratio value is lower than a preset value, so as to avoid directly unlocking the mobile phone every time the camera collects a face image, so as to improve the user experience.
