The approach detection method, the approach detection device 200 , the electronic device 100 , the computer-readable storage medium and the computer device 300 according to the embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 15 .

Referring to FIG. 1 to FIG. 4 , an embodiment of the present invention provides a method for approach detection of an electronic device 100 . The electronic device 100 includes an ambient light sensor 161 and a proximity sensor 162. The ambient light sensor 161 is used to obtain infrared light in ambient light, and the proximity sensor 162 is used to emit infrared light and receive infrared light reflected by objects. The proximity detection method includes the steps of:

S10. Acquire a first intensity value of infrared light in the current ambient light.

S20. Acquire a second intensity value of the infrared light received by the proximity sensor. and

S30. Detect the distance from the object to the electronic device according to the first intensity value and the second intensity value to determine whether the object is approaching or moving away from the electronic device.

The embodiment of the present invention also provides a proximity detection device 200 for the electronic device 100 . The approach detection method in the embodiment of the present invention can be implemented by the approach detection device 200 in the embodiment of the present invention. The approach detection device 200 includes an acquiring module 21 and a judging module 22 , step S10 and step S20 can be realized by the acquiring module 21 , and step S30 can be realized by the judging module 22 . That is, the acquiring module 21 can be used to acquire the first intensity value of the infrared light in the current ambient light and acquire the second intensity value of the infrared light received by the proximity sensor 162 . The judging module 22 can be used to detect the distance from the object to the electronic device 100 according to the first intensity value and the second intensity value to judge whether the object is approaching or moving away from the electronic device 100 .

The embodiment of the present invention also provides an electronic device 100 . The electronic device 100 includes an ambient light sensor 161 , a proximity sensor 162 and a processor 24 . Step S10 , step S20 and step S30 may be implemented by the processor 24 . That is to say, the processor 24 can be used to obtain the first intensity value of the infrared light received by the ambient light sensor 161 in the current ambient light and the second intensity value of the infrared light received by the proximity sensor 162, and according to the first intensity value and the second intensity value to detect the distance from the object to the electronic device 100 to determine whether the object is approaching or moving away from the electronic device 100 .

The embodiment of the present invention also provides a computer device 300 . In the embodiment of the present invention, the approach detection device 200 can be applied to the computer device 300 . The computer device 300 may be a mobile phone, a tablet computer, a notebook computer, a smart bracelet, a smart watch, a smart helmet, smart glasses, a game console, etc., and the electronic device 100 in the embodiment of the present invention may also be one of the computer devices 300 .

The embodiment of the present invention is described by taking the electronic device 100 as a mobile phone as an example. The ambient light sensor 161 and the proximity sensor 162 in the mobile phone realize adjusting the brightness of the screen according to the light intensity of the surrounding environment and detecting the distance between the electronic device 100 and the user, respectively. Please refer to FIG. 5 and FIG. 6. When performing ambient light detection, for example, when the user is in an outdoor environment and the ambient light is strong, the ambient light sensor 161 feeds back the light intensity of the environment to the processor, and the processor sends a corresponding The instruction is sent to the controller, and the controller increases the brightness of the display screen according to the instruction to adapt to the light intensity of the current environment, so that the user can watch the content of the screen more clearly. When the user is in a dark environment and the ambient light is weak, the ambient light sensor 161 will feed back the light intensity of the environment to the processor, and the processor will send a corresponding command to the controller, and the controller will reduce the brightness of the display screen according to the command. Adapt to the light intensity of the current environment, so that the user does not feel glare when viewing the screen content, so as to give the user the best visual effect.

Please refer to Fig. 7 and Fig. 8, when performing distance detection, for example, when the user is answering or making a call and the mobile phone is brought close to the head, the proximity sensor 162 sends out the infrared light intensity through the calculation transmitter and the receiver receives the reflected infrared light. The intensity of the light generates distance detection information, and the processor sends a corresponding instruction to the controller according to the distance detection information, and the controller turns off the screen according to the instruction. When the mobile phone is far away from the head, the processor calculates again according to the detection information fed back by the proximity sensor 162 and sends an instruction to the controller, and the controller reopens the screen according to the instruction.

However, in the actual application process of the proximity sensor, for example, in an outdoor environment under direct sunlight, since the sunlight contains infrared light, it will cause certain interference to the infrared light emitted by the proximity sensor itself, especially in electronic devices. At different receiving angles, the intensity of the infrared light received by the proximity sensor will fluctuate, so that the proximity sensor cannot accurately determine whether there is an object blocking or approaching the electronic device.

The proximity detection method, proximity detection device 200, electronic device 100, computer readable storage medium and computer equipment 300 of the embodiment of the present invention judge the object by detecting the intensity of the infrared light received by the proximity sensor 162 and the intensity of the infrared light in the ambient light The distance from the electronic device 100 can reduce the interference caused by ambient light to the detection of the proximity sensor 162 .

It should be noted that since the ambient light sensor 161 can also sense the infrared light emitted by the proximity sensor 162, the proximity sensor 162 can be turned on to emit infrared light after the ambient light sensor 161 acquires the first intensity value of the infrared light in the current ambient light. The distance detection can prevent the infrared light emitted by the proximity sensor 162 from interfering with the detection of the first intensity value. In addition, the installation position of the ambient light sensor 161 may be further away from the installation position of the proximity sensor 162 in terms of structural position. It can be understood that after acquiring the second intensity value of infrared light received by the proximity sensor 162, the ambient light sensor 161 can be turned on to acquire the first intensity value of infrared light in the current ambient light, and the timing is not specifically limited.

In addition, the distance from the object to the electronic device 100 can be calculated by taking the difference between the second intensity value and the first intensity value, so as to determine whether the object is approaching or moving away from the electronic device 100 according to the obtained distance. For example, in a normal state, when the intensity of infrared light received by the proximity sensor 162 is below 50 lumens (Lumen, lm), it indicates that the distance between the object or the human face and the electronic device 100 is above 90 mm, indicating that the object or the human face is far away from the electronic device. 100. When the intensity of the infrared light received by the proximity sensor 162 is above 200 lumens, it indicates that the distance between the object or the human face and the electronic device 100 is less than 50 mm, indicating that the object or the human face approaches the electronic device 100 . When the ambient light sensor 161 detects that the first intensity value of the infrared light in the ambient light is 70 lumens, and the second intensity value of the infrared light detected by the proximity sensor 162 is 85 lumens, the second intensity value is 85 lumens minus the first The intensity value is 15 lumens after 70 lumens (15 lumens is less than 50 lumens), indicating that the object or human face is far away from the electronic device 100 . When the ambient light sensor 161 detects that the first intensity value of the infrared light in the ambient light is 70 lumens, and the second intensity value of the infrared light detected by the proximity sensor 162 is 350 lumens, the second intensity value is 350 lumens minus the first intensity value. After the intensity value is 70 lumens, it becomes 280 lumens (280 lumens is greater than 200 lumens), indicating that there is an object or a human face approaching the electronic device 100 . It can be understood that these intensity values and distance values are only exemplary, and have no limiting effect on the present invention. The intensity value and the distance value can be set according to the specific situation.

Referring to FIG. 9, in some embodiments, the proximity detection method includes the steps of:

S101: Detect the brightness value of the current ambient light; and

S102: Acquire a first intensity value of infrared light in current ambient light when the brightness value is greater than or equal to a predetermined brightness threshold.

Referring to FIG. 3 , in some implementation manners, step S101 and step S102 may be implemented by the acquiring module 21 . That is to say, the acquiring module 21 can detect the brightness value of the current ambient light, and acquire the first intensity value of the infrared light in the current ambient light when the brightness value is greater than or equal to the preset brightness threshold.

Referring to FIG. 1 , in some implementations, step S101 and step S102 may be implemented by the processor 24 . That is, the processor 24 may obtain the brightness value of the current ambient light detected by the ambient light sensor 161, and obtain the first intensity value of the infrared light in the current ambient light when the brightness value is greater than or equal to a predetermined brightness threshold.

Specifically, please refer to FIG. 10 , when the user is in an outdoor environment, such as being exposed to the sun, the proximity sensor 162 is greatly affected by the infrared rays in the surrounding ambient light during the distance detection process, and it is more likely to cause the proximity sensor 162 to detect mistake. Therefore, when it is detected that the brightness value of the current ambient light is greater than or equal to the predetermined brightness threshold, obtaining the first intensity value of the infrared light in the ambient light is beneficial to reduce the interference caused by the ambient light to the detection of the proximity sensor 162 . It should be noted that the predetermined brightness threshold can be set according to specific situations. In addition, the brightness value of the ambient light can be calculated according to the sensitivity of the image sensor in the electronic device 100 .

Referring to Figure 11, in some embodiments, the approach detection method includes the steps of:

S103: If the brightness value is less than the preset brightness threshold, detect the distance from the object to the electronic device according to the second intensity value to determine whether the object is approaching or moving away from the electronic device.

Referring to FIG. 3 , in some implementation manners, step S103 may be implemented by the judging module 22 . That is to say, the judging module 22 can detect the distance from the object to the electronic device 100 according to the second intensity value to judge whether the object is approaching or moving away from the electronic device 100 when the brightness value is less than the predetermined brightness threshold.

Referring to FIG. 1 , in some implementation manners, step S103 may be implemented by the processor 24 . That is to say, the processor 24 may detect the distance from the object to the electronic device 100 according to the second intensity value to determine whether the object is approaching or moving away from the electronic device 100 when the brightness value is less than the predetermined brightness threshold.

Specifically, when the luminance value is less than the predetermined brightness threshold, the infrared light in the current light environment has less influence on the proximity sensor 162 . For example, when the user is in a low-light environment such as indoors, there is less infrared light in the ambient light, and the impact on the proximity sensor 162 is negligible, so the second intensity value detected by the proximity sensor 162 can be directly used for distance detection. Work.

Referring to FIG. 11, in some implementations, the step S101 of detecting the brightness value of the current ambient light includes:

S1011, acquiring multiple frames of images of the current environment; and

S1012. Calculate the brightness value of the current environment according to the multiple frames of images.

Referring to FIG. 3 , in some implementations, the proximity detection device 200 includes a calculation module 23 . Step S1011 can be implemented by the acquisition module 21 , and step S1012 can be implemented by the calculation module 23 . That is to say, the acquisition module 21 can acquire multiple frames of images of the current environment, and the calculation module 23 can calculate the brightness value of the current environment according to the multiple frames of images.

Referring to FIG. 1 , in some implementations, the electronic device 100 includes a camera 163 , and step S1011 and step S1012 can be implemented by the processor 24 . That is to say, the processor 24 can use the camera 163 to obtain multiple frames of images of the current environment, and calculate the brightness value of the current environment according to the multiple frames of images.

Specifically, the brightness value of the current environment may also be obtained by detecting images captured by the camera 163 . For example, the brightness value of the current environment can be calculated according to the brightness of the captured image. It can be understood that these manners of detecting ambient light are only exemplary, and have no limiting effect on the present invention, and the manner of detecting ambient light may also be in other forms.

Please refer to FIG. 12 , in some implementations, the step S10 of acquiring the first intensity value of infrared light in the current ambient light when the brightness value is greater than or equal to the predetermined brightness threshold value includes:

S104, detecting the tilt angle of the electronic device; and

S105. Acquire a first intensity value of infrared light in the current ambient light when the tilt angle is smaller than the predetermined angle threshold.

Referring to FIG. 3 , in some implementation manners, step S104 and step S105 may be implemented by the acquisition module 21 . That is to say, the acquisition module 21 can detect the tilt angle of the electronic device 100, and acquire the first intensity value of the infrared light in the current ambient light when the tilt angle is smaller than the predetermined angle threshold.

Referring to FIG. 1 , in some implementations, the electronic device 100 includes an acceleration sensor 164 , and step S104 and step S105 can be implemented by the processor 24 . That is to say, the processor 24 can use the acceleration sensor 164 to detect the inclination angle of the electronic device 100, and when the inclination angle is smaller than the predetermined angle threshold, acquire the first intensity value of the infrared light in the current ambient light.

Specifically, please refer to FIG. 13 , at this moment, the inclination angle of the electronic device 100 is 0 degree (the electronic device 100 is parallel to the horizontal direction). Please refer to FIG. 14 , at this time, the tilt angle of the electronic device 100 is 30 degrees (the angle between the electronic device 100 and the horizontal direction is 30 degrees). The proximity sensor 162 is more likely to receive infrared light in ambient light, and has a greater impact on the proximity sensor 162. Therefore, when the tilt angle of the electronic device 100 is less than the predetermined angle threshold, it can detect the intensity of the infrared light received by the proximity sensor 162. Judging the distance between the object and the electronic device 100 based on the intensity of the infrared light in the ambient light can reduce the interference caused by the ambient light to the detection of the proximity sensor 162 . In addition, the inclination angle of the electronic device 100 may also include the inclination angle of the electronic device 100 with respect to the vertical direction. The tilt angle of the detection electronic device 100 may also be detected by a gravity sensor or a gyroscope sensor. It can be understood that the specific data of the predetermined threshold value of the angle can be set according to the actual situation.

Referring to FIG. 12, in some embodiments, the proximity detection method includes the steps of:

S106. If the tilt angle is greater than or equal to the predetermined angle threshold, detect the distance from the object to the electronic device according to the second intensity value to determine whether the object is approaching or moving away from the electronic device.

Referring to FIG. 3 , in some implementations, step S106 may be implemented by the judging module 22 . That is to say, the judging module 22 can detect the distance from the object to the electronic device 100 according to the second intensity value to judge whether the object is approaching or moving away from the electronic device 100 when the tilt angle is greater than or equal to the predetermined angle threshold.

Referring to FIG. 1 , in some implementations, step S106 may be implemented by the processor 24 . That is to say, the processor 24 may detect the distance from the object to the electronic device 100 according to the second intensity value to determine whether the object is approaching or moving away from the electronic device 100 when the tilt angle is greater than or equal to the predetermined threshold.

Specifically, please refer to FIG. 15 , at this moment, the tilt angle of the electronic device 100 is 120 degrees. The proximity sensor 162 seldom receives infrared light in ambient light, and the impact on the proximity sensor 162 is negligible, so the second intensity value detected by the proximity sensor 162 can be directly used for distance detection.

The embodiment of the present invention also provides a computer-readable storage medium.
