Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A proximity detection method, a proximity detection apparatus 200, an electronic apparatus 100, a computer-readable storage medium, and a computer device 300 according to embodiments of the present invention are described in detail below with reference to fig. 1 to 15.
Referring to fig. 1 to 4, an embodiment of the invention provides a proximity detection method for an electronic device 100. The electronic device 100 includes an ambient light sensor 161 and a proximity sensor 162, the ambient light sensor 161 for acquiring infrared light in ambient light, and the proximity sensor 162 for emitting infrared light and receiving infrared light reflected by an object. The approach detection method includes the steps of:
s10, a first intensity value of the infrared light in the current ambient light is obtained.
S20, a second intensity value of the infrared light received by the proximity sensor is obtained. And
and S30, detecting the distance from the object to the electronic device according to the first intensity value and the second intensity value to judge whether the object is close to or far away from the electronic device.
The embodiment of the invention also provides a proximity detection device 200 for the electronic device 100. The proximity detection method according to the embodiment of the present invention can be realized by the proximity detection device 200 according to the embodiment of the present invention. The proximity detection device 200 includes an acquisition module 21 and a determination module 22, and steps S10 and S20 may be implemented by the acquisition module 21, and step S30 may be implemented by the determination module 22. That is, the obtaining module 21 may be configured to obtain a first intensity value of the infrared light in the current ambient light and obtain a second intensity value of the infrared light received by the proximity sensor 162. The determining module 22 can be used for detecting a distance from the object to the electronic device 100 according to the first intensity value and the second intensity value to determine whether the object is close to or far away from the electronic device 100.
The embodiment of the 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, the processor 24 is configured to obtain a first intensity value of the infrared light in the current ambient light received by the ambient light sensor 161 and obtain a second intensity value of the infrared light received by the proximity sensor 162, and detect a distance from the object to the electronic device 100 according to the first intensity value and the second intensity value to determine whether the object is close to or far from the electronic device 100.
The embodiment of the invention also provides computer equipment 300. In an embodiment of the present invention, the proximity detection apparatus 200 may be employed in a computer device 300. The computer device 300 may be a mobile phone, a tablet computer, a notebook computer, an intelligent bracelet, an intelligent watch, an intelligent helmet, an intelligent glasses, a game console, and the like, and the electronic apparatus 100 according to 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 respectively realize the adjustment of the screen brightness according to the intensity of the ambient light and the detection of the distance between the electronic device 100 and the user. Referring to fig. 5 and 6, when the ambient light detection is performed, 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, the processor sends a corresponding instruction 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 content of the screen viewed by the user is clearer. When the user is in a dark environment, the ambient light is weak, the ambient light sensor 161 feeds back the light intensity of the environment to the processor, the processor sends a corresponding instruction to the controller, and the controller reduces the brightness of the display screen according to the instruction to adapt to the light intensity of the current environment, so that the user does not feel dazzling when watching the screen content, and the optimal visual effect is provided for the user.
Referring to fig. 7 and 8, when distance detection is performed, for example, when a user is receiving or making a call and brings a mobile phone close to the head, the proximity sensor 162 calculates intensity of infrared light emitted by the emitter and intensity of infrared light reflected by the receiver to generate distance detection information, the processor sends a corresponding instruction to the controller according to the distance detection information, and the controller closes the screen according to the instruction. When the mobile phone is far away from the head, the processor calculates and sends an instruction to the controller again according to the detection information fed back by the proximity sensor 162, and the controller reopens the screen according to the instruction.
However, in the practical application process of the proximity sensor, for example, in an outdoor use environment in which sunlight is directly emitted, since the sunlight contains infrared light, certain interference is caused to the infrared light emitted by the proximity sensor itself, and particularly, when the electronic device is at different receiving angles, the proximity sensor fluctuates due to the intensity of the received infrared light, so that the proximity sensor cannot accurately judge whether an object is blocked or approaches the electronic device.
The proximity detection method, the proximity detection apparatus 200, the electronic apparatus 100, the computer-readable storage medium, and the computer device 300 according to the embodiments of the present invention can reduce interference of the ambient light with detection of the proximity sensor 162 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 to determine the distance between the object and the electronic apparatus 100.
It should be noted that, since the ambient light sensor 161 can also sense the infrared light emitted by the proximity sensor 162, after the ambient light sensor 161 obtains the first intensity value of the infrared light in the current ambient light, the proximity sensor 162 may be turned on to emit the infrared light for distance detection, so as to avoid interference of the infrared light emitted by the proximity sensor 162 on detection of the first intensity value. In addition, the installation position of the ambient light sensor 161 may be set to be distant from the installation position of the proximity sensor 162. It is to be understood that after the second intensity value of the infrared light received by the proximity sensor 162 is obtained, the ambient light sensor 161 may be turned on to obtain the first intensity value of the infrared light in the current ambient light, and the timing sequence is not limited specifically.
In addition, the distance from the object to the electronic device 100 may be calculated by subtracting the first intensity value from the second intensity value, so as to determine whether the object is close to or far 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 90mm, which indicates 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 below 50mm, indicating that the object or the human face approaches the electronic device 100. When ambient light sensor 161 detects a first intensity value of 70 lumens for infrared light in the ambient light and proximity sensor 162 detects a second intensity value of 85 lumens for infrared light, subtracting the first intensity value of 70 lumens from the second intensity value of 85 lumens is 15 lumens (15 lumens is less than 50 lumens), indicating that the object or face is far from electronic device 100. When ambient light sensor 161 detects a first intensity value of 70 lumens for infrared light in the ambient light and proximity sensor 162 detects a second intensity value of 350 lumens for infrared light, the subtraction of the first intensity value of 70 lumens from the second intensity value of 350 lumens is 280 lumens (280 lumens is greater than 200 lumens), indicating that an object or a human face is in proximity to electronic device 100. It will be appreciated that these intensity values and distance values are exemplary only and are not limiting to the invention. The intensity value and the distance value can be set according to specific situations.
Referring to fig. 9, in some embodiments, a proximity detection method includes the steps of:
s101: detecting the brightness value of the current environment light; and
s102: when the brightness value is larger than or equal to a preset brightness threshold value, a first intensity value of infrared light in current environment light is acquired.
Referring to fig. 3, in some embodiments, step S101 and step S102 may be implemented by the obtaining module 21. That is, the obtaining module 21 may detect a brightness value of the current ambient light, 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.
Referring to fig. 1, in some embodiments, steps S101 and S102 may be implemented by the processor 24. That is, the processor 24 may acquire the brightness value of the current ambient light detected by the ambient light sensor 161 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 brightness predetermined threshold.
Specifically, referring to fig. 10, when the user is in an outdoor environment, such as exposed to the sun, the proximity sensor 162 is greatly affected by infrared rays in the ambient light during the distance detection process, and thus a detection error of the proximity sensor 162 is more likely to be caused. Therefore, when it is detected that the brightness value of the current ambient light is greater than or equal to the brightness predetermined threshold, acquiring the first intensity value of the infrared light in the ambient light is beneficial to reducing the interference caused by the ambient light on the detection of the proximity sensor 162. The predetermined brightness threshold may be set according to specific situations. Further, the luminance value of the ambient light may be calculated by the level of sensitivity of the image sensor in the electronic device 100.
Referring to fig. 11, in some embodiments, a proximity detection method includes the steps of:
s103: if the brightness value is smaller than the preset brightness threshold value, the distance from the object to the electronic device is detected according to the second intensity value to judge whether the object is close to or far away from the electronic device.
Referring to fig. 3, in some embodiments, step S103 may be implemented by the determining module 22. That is, the determining module 22 may detect the distance from the object to the electronic device 100 according to the second intensity value when the brightness value is smaller than the predetermined brightness threshold to determine whether the object is close to or far away from the electronic device 100.
Referring to fig. 1, in some embodiments, step S103 may be implemented by the processor 24. That is, the processor 24 may detect the distance from the object to the electronic device 100 according to the second intensity value when the brightness value is smaller than the predetermined brightness threshold to determine whether the object is close to or far from the electronic device 100.
Specifically, when the brightness value is less than the predetermined threshold value of brightness, 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, since infrared light in ambient light is small and the influence on the proximity sensor 162 is negligible, the distance detection operation can be performed using the second intensity value detected by the proximity sensor 162 as it is.
Referring to fig. 11, in some embodiments, the step S101 of detecting the brightness value of the current ambient light includes:
s1011, acquiring a multi-frame image of the current environment; and
s1012, a luminance value of the current environment is calculated from the plurality of frames of images.
Referring to fig. 3, in some embodiments, the proximity detection apparatus 200 includes a calculation module 23. Step S1011 may be implemented by the obtaining module 21, and step S1012 may be implemented by the calculating module 23. That is, the obtaining module 21 may obtain a multi-frame image of the current environment, and the calculating module 23 may calculate the brightness value of the current environment according to the multi-frame image.
Referring to fig. 1, in some embodiments, the electronic device 100 includes the camera 163, and steps S1011 and S1012 can be implemented by the processor 24. That is, the processor 24 may acquire a plurality of frame images of the current environment by using the camera 163, and calculate the brightness value of the current environment from the plurality of frame images.
Specifically, the brightness value of the current environment may also be obtained by detecting the image captured by the camera 163. For example, the luminance value of the current environment may be calculated from the brightness of the captured image. It is understood that these ways of detecting the ambient light are only exemplary, and do not limit the present invention, and that the ways of detecting the ambient light may be other forms.
Referring to fig. 12, in some embodiments, the step S10 of acquiring the first intensity value of the infrared light in the current ambient light when the brightness value is greater than or equal to the predetermined brightness threshold includes:
s104, detecting the inclination angle of the electronic device; and
and S105, when the inclination angle is smaller than the preset angle threshold, acquiring a first intensity value of the infrared light in the current ambient light.
Referring to fig. 3, in some embodiments, step S104 and step S105 may be implemented by the obtaining module 21. That is, the obtaining module 21 may detect the tilt angle of the electronic device 100, and obtain 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 embodiments, the electronic device 100 includes an acceleration sensor 164, and step S104 and step S105 can be implemented by the processor 24. That is, the processor 24 may detect the tilt angle of the electronic device 100 by using the acceleration sensor 164, and obtain the first intensity value of the infrared light in the current ambient light when the tilt angle is smaller than the predetermined angle threshold.
Specifically, please refer to fig. 13, in which the tilt angle of the electronic device 100 is 0 degree (the electronic device 100 is parallel to the horizontal direction). Referring to fig. 14, the tilt angle of the electronic device 100 is 30 degrees (the included angle between the electronic device 100 and the horizontal direction is 30 degrees). The proximity sensor 162 can more easily receive the infrared light in the ambient light, and the influence on the proximity sensor 162 is large, so when the tilt angle of the electronic device 100 is smaller than the predetermined angle threshold, the distance between the object and the electronic device 100 can be determined 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, and the interference caused by the detection of the proximity sensor 162 by the ambient light can be reduced. In addition, the tilt angle of the electronic device 100 may also include a tilt angle of the electronic device 100 from a vertical direction. The tilt angle of the electronic device 100 may be detected by a gravity sensor or a gyro sensor. It is understood that the specific data of the predetermined angle threshold can be set according to actual conditions.
Referring to fig. 12, in some embodiments, a proximity detection method includes the steps of:
and S106, if the inclination angle is larger than or equal to the preset angle threshold, detecting the distance from the object to the electronic device according to the second intensity value to judge whether the object is close to or far away from the electronic device.
Referring to fig. 3, in some embodiments, step S106 may be implemented by the determining module 22. That is, the determining module 22 may detect the distance from the object to the electronic device 100 according to the second intensity value when the tilt angle is greater than or equal to the predetermined angle threshold to determine whether the object is close to or far from the electronic device 100.
Referring to fig. 1, in some embodiments, step S106 may be implemented by the processor 24. That is, the processor 24 may detect the distance from the object to the electronic device 100 according to the second intensity value when the tilt angle is greater than or equal to the predetermined angle threshold to determine whether the object is close to or far from the electronic device 100.
Specifically, please refer to fig. 15, the tilt angle of the electronic device 100 is 120 degrees. The proximity sensor 162 receives less infrared light in the ambient light, and the influence on the proximity sensor 162 is negligible, so that the distance detection operation can be performed directly using the second intensity value detected by the proximity sensor 162.
The embodiment of the invention also provides a computer readable storage medium. One or more non-transitory computer-readable storage media containing computer-executable instructions that, when executed by the one or more processors 24, cause the processors 24 to perform the proximity detection method of any of the embodiments described above. For example, step S10 is executed to obtain a first intensity value of the infrared light in the current ambient light. In step S20, a second intensity value of the infrared light received by the proximity sensor is acquired. And step S30, detecting the distance from the object to the electronic device according to the first intensity value and the second intensity value to judge whether the object is close to or far away from the electronic device.

The computer device includes a memory 32 and a processor 24, wherein the memory 32 stores computer readable instructions, and when the instructions are executed by the processor 24, the processor 24 executes the proximity detection method according to any of the embodiments.
