Detailed ways

The technical solutions of the present application will be further described below with reference to the accompanying drawings and through specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all the structures related to the present application.

Before discussing the exemplary embodiments in greater detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowchart depicts the steps as a sequential process, many of the steps may be performed in parallel, concurrently, or concurrently. Furthermore, the order of the steps can be rearranged. The process may be terminated when its operation is complete, but may also have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

In order to facilitate the understanding of the technical solutions of the embodiments of the present application, a related introduction to the proximity sensor is given below. At present, proximity sensors have been widely used in various mobile terminals, and use proximity sensors to achieve various functions, such as preventing misoperation caused by the face touching the screen during a call, automatically adjusting the backlight, and recognizing the gesture of turning off the touch screen, etc. Common proximity sensors include optical proximity sensors (also known as optical proximity sensors or proximity light sensors), which emit light outward, and then determine the distance between the object and the sensor by measuring the intensity of the light reflected back by the object. Among them, the infrared optical proximity sensor (also known as the infrared proximity sensor) is one of the most widely used optical proximity sensors.

In the embodiment of the present application, the specific type of the optical proximity sensor is not limited. For the convenience of description, the infrared proximity sensor will be used as an example for description below, and it will be referred to as a proximity sensor in the following embodiments. The infrared proximity sensor emits infrared rays outward, and then judges the distance between the object and the sensor by measuring the infrared intensity reflected back by the object. The stronger the received infrared light intensity, the smaller the distance between it and the object. Within a certain measurement range, the infrared proximity sensor will convert the measured infrared intensity into a measurement value that is proportional to the measurement value, which may be called a proximity value. Generally, the proximity value may be an output value of an analog-to-digital converter (Analog-to-Digital Converter, ADC) in the infrared proximity sensor, referred to as an ADC value or an AD value for short. The larger the proximity value from the infrared proximity sensor, the smaller the distance between it and the object.

In order for the infrared proximity sensor to detect the approaching or moving away of an object, a determination threshold value for determining the approaching state or the moving away state is generally set in advance. The determination threshold value may include a near threshold value, and may also include a near threshold value and a far away threshold value. Exemplarily, if it is determined that the threshold value only includes the proximity threshold value, when the current proximity value of the infrared proximity sensor is greater than the proximity threshold value, it can be determined as a proximity state; when the current proximity value of the infrared proximity sensor is less than the proximity threshold value , it can be judged to be in the far away state. Exemplarily, if the determination threshold value includes a proximity threshold value and a distance threshold value, when the current proximity value of the infrared proximity sensor is greater than the proximity threshold value, it can be determined as a proximity state; when the current proximity value of the infrared proximity sensor is less than When it is far away from the threshold value, it can be determined as the far away state; when the current proximity value of the infrared proximity sensor is between the far away threshold value and the near threshold value, the state at the last determination is kept unchanged. Generally, affected by the environment and other factors, the proximity value of the infrared proximity sensor may also fluctuate within a small range when the user's usage status is basically unchanged. Generally, the judgment threshold value includes both approaching the threshold value and far from the threshold value. After determining the approaching or away state, the mobile terminal can be controlled to perform corresponding operations, for example, during a call, the screen is turned off in the approaching state, and the screen is turned on in the away state.

However, the infrared light contained in the environment will have a certain influence on the proximity value of the infrared proximity sensor, because after the infrared proximity sensor emits infrared light, the infrared light received not only includes the infrared light reflected back by the object, but also includes the infrared light in the environment. Infrared light is present, so the approximate value obtained is larger than the actual value. Therefore, how to reasonably set the judgment threshold value of the proximity sensor becomes a technical problem.

1 is a schematic flowchart of a method for controlling a proximity sensor provided by an embodiment of the present application. The method may be executed by a control device for a proximity sensor, where the device may be implemented by software and/or hardware, and may generally be integrated in a mobile terminal. As shown in Figure 1, the method includes:

Step 101: Obtain attitude information of the mobile terminal.

Exemplarily, the mobile terminal in this embodiment of the present application may include mobile devices such as mobile phones and tablet computers equipped with proximity sensors.

Generally, in order to take into account the user's habit of holding the mobile terminal, the proximity sensor is arranged on the top of the front of the mobile terminal, for example, near the front camera, and of course, it may also be arranged near the lift camera (for example, the periscope camera).

In the user's daily use process, the light source in the environment, such as light or sunlight, is generally located above the user's head. Therefore, when the posture of the mobile terminal is different, the received ambient light may be different. For example, when the mobile terminal is in a horizontal state, more ambient light may be received; and when the mobile terminal is in an upright state, less ambient light may be received. Therefore, when the mobile terminal is in different postures, the influence of ambient light on the proximity sensor may be different. In this embodiment of the present application, the attitude information of the mobile terminal is acquired, so as to more reasonably determine the threshold value of the proximity sensor for determining the approaching state or the distant state in the subsequent steps.

Exemplarily, a mobile terminal may be provided with many motion sensors, such as an acceleration sensor, a gyroscope sensor, a magnetometer, and the like. In this embodiment of the present application, the posture information of the mobile terminal may be acquired through one or more motion sensors integrated in or external to the mobile terminal. Optionally, the attitude information may include the orientation of the mobile terminal, the angle of the front of the mobile terminal relative to the reference plane, the angle of each side of the mobile terminal relative to each coordinate axis of the reference coordinate system, and which preset category the mobile terminal is in. The pose category and so on.

Optionally, the mobile terminal may acquire the attitude information of the mobile terminal in real time, may also acquire the attitude information of the mobile terminal periodically, and may also acquire the attitude information of the mobile terminal when receiving an instruction for acquiring attitude information. For example, when it is detected that a preset gesture acquisition event is triggered, the gesture information of the mobile terminal is acquired. The conditions for triggering the preset gesture acquisition event are not limited in this embodiment of the present application. For example, when it is detected that the current environment meets the preset requirements, a preset posture acquisition event is triggered; for another example, when it is detected that the proximity sensor enters a working state, a preset posture acquisition event is triggered; When triggered, trigger a preset pose acquisition event and so on.

Step 102: Determine the corresponding target threshold value of the proximity sensor according to the attitude information.

Exemplarily, the threshold values corresponding to different attitude information can be preset, and the corresponding relationship between the attitude and the threshold value can be obtained and stored in the mobile terminal. The corresponding threshold value in the information search correspondence is taken as the target threshold value. In order to simplify the corresponding relationship, the attitude information can be classified, and each type of attitude information corresponds to a threshold value.

Optionally, in addition to using the attitude information as a reference factor for determining the target threshold value of the proximity sensor, other reference factors may also be used for determining the target threshold value. For example, it is also possible to refer to the current environmental conditions, such as the light intensity value of the current environment. Exemplarily, this step may include determining the correspondence of the proximity sensor according to the posture information and the light intensity value of the current environment (for the convenience of distinguishing from other light intensity values next, it may be referred to as a third light intensity value here). target threshold value. The advantage of this setting is that the target threshold value can be determined more reasonably. In the embodiment of the present application, how to determine the target threshold value according to the two reference factors at the same time is not limited. Exemplarily, the light intensity value may be divided into multiple intervals, and each light intensity interval corresponds to a set of correspondences between attitudes and threshold values. Obtain the third light intensity value of the current environment, determine the correspondence between the corresponding attitude and the threshold value according to the light intensity interval to which the third light intensity value belongs, and then query the determined correspondence between the attitude and the threshold value according to the current attitude information, Get the target threshold value.

Step 103: Control the proximity sensor to determine an approaching state or a distant state based on the target threshold value.

Exemplarily, the target threshold value determined according to the attitude information is more in line with the current test scene, and the influence of ambient light on the approach value under different attitudes is fully considered, so that the proximity sensor can more accurately determine the approaching state or the away state, preventing Misjudgment occurs.

After determining the approaching or moving away state, the mobile terminal can be controlled to perform corresponding operations. For example, during a call, the screen is turned off in the approaching state, and the screen is turned on in the far-away state.

In the control method of the proximity sensor provided in the embodiment of the present application, the attitude information of the mobile terminal is obtained, the corresponding target threshold value of the proximity sensor is determined according to the attitude information, and the proximity sensor is controlled to determine the proximity state or the distance state based on the target threshold value. . By adopting the above technical solution, the threshold value of the proximity sensor for judging the approaching state or the distant state can be adaptively determined according to the attitude information of the mobile terminal, so that the threshold value can be reasonably set and the determination accuracy of the proximity sensor can be ensured.

In some embodiments, before the acquiring the gesture information of the mobile terminal, the method includes: acquiring a first light intensity value of the current environment; when the first light intensity value is greater than a first preset light intensity threshold, triggering acquisition of movement Attitude information of the terminal. Generally, when the ambient light around the mobile terminal is not strong, the influence on the proximity value of the proximity sensor is small, and when acquiring attitude information, the operation of the motion sensor may generate a certain amount of power consumption. When the first light intensity value is greater than the first preset light intensity threshold, the acquisition of the attitude information of the mobile terminal is triggered again, so as to save the power consumption of the mobile terminal.

In some embodiments, the determining the corresponding target threshold value of the proximity sensor according to the attitude information includes: determining, according to the attitude information, that the angle between the front of the mobile terminal and the horizontal plane is smaller than a first preset When the angle threshold is determined, the corresponding target threshold value of the proximity sensor is determined as the first target threshold value; when it is determined according to the attitude information that the angle between the front of the mobile terminal and the horizontal plane is greater than the second preset angle threshold, Determine the corresponding target threshold value of the proximity sensor as the second target threshold value; wherein, the first preset angle threshold value is smaller than the second preset angle threshold value, and the first target threshold value is greater than the first target threshold value Two target thresholds. The advantage of this setting is that the threshold value of the proximity sensor of the mobile terminal in the horizontal state and the erect state can be reasonably set, so as to prevent misjudgment from occurring. When the angle between the front of the mobile terminal and the horizontal plane is small, it means that the mobile terminal is basically in a flat state, and the user may hold the mobile terminal to view the screen content. The flat state here is not absolutely horizontal, because the user is generally holding the mobile terminal. At this time, in order to facilitate the viewing of the screen, there will be a slight inclination. At this time, the proximity sensor receives a large amount of ambient light and is easily affected by ambient light. Therefore, the corresponding target threshold value can be set larger to prevent misunderstanding The far-away state is determined as the approaching state; and when the included angle of the mobile terminal relative to the horizontal plane is large, it means that the mobile terminal is basically in an erected state, and the user may erect the mobile terminal to answer the call. The erected state here is not absolutely perpendicular to the horizontal plane. Because the user generally puts the mobile terminal close to the ear, there will also be a slight tilt. At this time, the proximity sensor receives a small amount of ambient light and is not easily affected by the ambient light. Therefore, the corresponding target threshold value can be set. is smaller, to prevent misjudging the approaching state as the far-away state. In this embodiment of the present application, the first preset angle threshold and the second preset angle threshold are not specifically limited, for example, they may be 40 degrees and 70 degrees, respectively. In this embodiment of the present application, the first target threshold value and the second target threshold value are not specifically limited, and may be set according to the specific configuration of the proximity sensor and other specific conditions.

Exemplarily, for a strong light environment, such as a sunny environment, the infrared intensity is very high, which may easily lead to abnormal working conditions of the infrared proximity sensor device, and the proximity value may jump frequently, such as from a relatively small one in a short time. The value jumps to a large value, and then jumps back to a smaller value, which in turn leads to a misjudgment of the approaching state of an external object, and the screen may frequently switch between off and on. Assuming that the user wants to perform other operations on the screen during the call in the outdoor sunshine, such as entering an extension number, viewing the address book or viewing the map and other information, the screen will be away from the user's head. Due to the influence of infrared rays in sunlight, the proximity value frequently jumps, so the screen will frequently switch between off and on, which seriously affects the normal operation of the user on the screen. In order to avoid the above problems, in a strong light environment, for example, when the first light intensity value is greater than the first preset light intensity threshold value, the first target threshold value is set to be larger, for example, close to the maximum boundary of the range. , assuming that the maximum boundary value of the proximity value range is 1023, the first target threshold value may be 900 for the proximity threshold and 850 for the remote threshold.

Exemplarily, since the second target threshold value is used in the case where the influence of ambient light is small, the minimum proximity value measured when it is not blocked in a non-strong light environment (such as 500 lux) can be determined as the second target threshold. limit. The second target threshold value may be set by default before the mobile terminal leaves the factory, or may be automatically determined after the mobile terminal leaves the factory. For example, each time the mobile terminal is powered on, it detects the fourth light intensity value of the current environment, and if the fourth light intensity value is smaller than the fourth preset light intensity threshold (eg, 500 lux), it measures the proximity value multiple times, and the measured The smallest approach value of is determined as the second target threshold value. Optionally, the mobile terminal will generally be calibrated on the production line before leaving the factory to obtain the calibration proximity value in a non-strong light environment. If the minimum proximity value measured above is smaller than the calibration proximity value, the calibration proximity value can be used as the second value. target threshold value. For example, the second target threshold value may be 450 for the approaching threshold and 350 for the farthest threshold.

In some embodiments, the acquiring the gesture information of the mobile terminal includes: acquiring the gesture information of the mobile terminal when detecting that the handset listening event is triggered. The advantage of this setting is that when it is detected that the earpiece listening event is triggered, it means that the user may have the action of placing the mobile terminal to the ear, and the gesture information of the mobile terminal needs to be identified, so as to determine the corresponding target threshold value in time .

In some embodiments, the determining that the corresponding target threshold value of the proximity sensor is the second target threshold value includes: determining the corresponding target threshold value of the proximity sensor as the first preset threshold value and the preset superposition The sum of the values, wherein the preset superimposed value is related to the influence of oil pollution produced by human skin on the proximity sensor. The advantage of this setting is that the second target threshold value is determined according to the sum of the preset threshold value and the preset superposition value corresponding to the influence of oil pollution, which can fully consider the skin on the face or ear when the user puts the mobile terminal to the ear. The influence of the generated oil pollution on the proximity sensor, so as to determine the target threshold value more accurately. The preset superimposed value may be referred to as the oil pollution value. For example, the variation of the proximity value of multiple mobile terminals under different oil pollution conditions relative to that without oil pollution may be collected, and the largest variation may be determined as the oil pollution value. For example, the oil stain value may be 60. The first preset threshold value may be set by default before the mobile terminal leaves the factory, or may be automatically determined after the mobile terminal leaves the factory. For example, each time the mobile terminal is powered on, the second light intensity value of the current environment is obtained; when the second light intensity value is smaller than the second preset light intensity threshold, the current proximity value of the proximity sensor is obtained as the A first preset threshold, wherein the second preset light intensity threshold is less than or equal to the first preset light intensity threshold. Optionally, acquiring the current proximity value of the proximity sensor as the first preset threshold value may include: acquiring the current proximity value of the proximity sensor multiple times, and using the acquired minimum value as the first preset threshold value. Preset threshold value. Optionally, the mobile terminal will generally be calibrated on the production line before leaving the factory to obtain the calibration proximity value in a non-strong light environment. If the minimum current proximity value obtained above is smaller than the calibration proximity value, the calibration proximity value can be used as the first value. Preset threshold value.

In some embodiments, the method may further include: acquiring attribute information of the current user; and determining a corresponding preset overlay value according to the attribute information. The advantage of this setting is that, due to the differences in the skin texture of different users, the degree of oil production may be different. Therefore, the influence of oil pollution on the proximity value may be different, and the preset superposition value can be determined more targetedly, and furthermore The second target threshold value is accurately determined. Exemplarily, the attribute information of the user may include gender, age, occupation, skin type, and the like. The big data method can be used in advance to analyze the influence of the user's skin oil corresponding to different user attribute information on the proximity value of the proximity sensor, and then determine the corresponding preset superimposed value to form the corresponding relationship between the user attribute information and the preset superimposed value, and Stored in the mobile terminal, or delivered to the mobile terminal by the server. When the screen of the mobile terminal is unlocked, the user can be identified through information such as fingerprints, and then the attribute information corresponding to the user with the current identity can be obtained, and the corresponding relationship between the above-mentioned user attribute information and the preset overlay value can be queried to obtain the corresponding preset overlay value. value. Further, in different weathers or different time periods, the oily situation of the user's skin may also be different. For example, in spring and summer or at noon, the skin is prone to oily skin, while in autumn and winter or in the morning and evening, the skin is not prone to oily production, etc. Another example is that when the temperature is high, the skin is prone to oil, and when the temperature is low, the skin is not easy to oil. Therefore, the preset overlay value may be further determined in combination with, for example, weather, season or time period. For example, attribute information, current weather information, and current time period of the current user are acquired, and a corresponding preset overlay value is determined according to the attribute information, the current weather information, and the current time period.

FIG. 2 is a schematic flowchart of another method for controlling a proximity sensor provided by an embodiment of the present application, and the method includes the following steps:

Step 201: Obtain a first light intensity value of the current environment.

Exemplarily, the ambient light can be detected by the ambient light sensor, and the current measurement value of the ambient light sensor can be used as the first light intensity value of the current environment; the ambient light can also be detected by the light receiver of the proximity sensor itself, to Taking an infrared proximity sensor as an example, the value of the measured infrared light intensity may be used as the first preset light intensity.

Step 202 , determine whether the first light intensity value is greater than the first preset light intensity threshold, and if so, perform step 203 ; otherwise, perform step 202 repeatedly.

Exemplarily, the corresponding first preset light intensity threshold may be determined according to the acquisition method of the first light intensity value, and the corresponding first preset light intensity threshold may also be different for different proximity sensors due to differences in materials, manufacturing processes, and ranges. different. Exemplarily, generally, when the ambient light intensity value is greater than 3000 lux (lux), the influence on the proximity value is greater, and it can be regarded as a strong light environment, and 3000 lux can be set as the first preset light intensity threshold.

Step 203: Detect whether the earpiece listening event is triggered, if yes, execute step 204; otherwise, execute step 203 repeatedly.

Exemplarily, when an incoming call or an outgoing phone call is detected, the earpiece listening event can be triggered; or when it is detected that the earpiece is about to play a sound, the earpiece listening event can be triggered.

Step 204: Acquire attitude information of the mobile terminal.

Step 205: Determine the included angle of the front face of the mobile terminal relative to the horizontal plane according to the attitude information.

Exemplarily, the attitude information may be acquired by a triaxial acceleration sensor, and the angle between the front face of the mobile terminal and the horizontal plane is calculated according to the output value of the triaxial acceleration sensor.

Step 206 , judging whether the included angle is smaller than the first preset angle threshold, if yes, go to step 207 ; otherwise, go to step 208 .

Exemplarily, the first preset angle threshold may be 40 degrees.

Step 207 , determine that the corresponding target threshold value of the proximity sensor is the first target threshold value, and execute step 211 .

Exemplarily, when the included angle between the front of the mobile terminal and the horizontal is less than 40 degrees, it means that the mobile terminal is basically in a horizontal state, the user may view the screen or perform operations on the screen during the call, and the proximity value of the proximity sensor is relatively affected by strong light. is larger, the target threshold value at this time is determined as the larger first target threshold value.

Step 208 , determine whether the included angle is greater than the second preset angle threshold, if yes, go to step 209 ; otherwise, go to step 210 .

Exemplarily, the second preset angle threshold may be 70 degrees.

Step 209 , determine that the corresponding target threshold value of the proximity sensor is the second target threshold value, and perform step 211 .

Wherein, the first preset angle threshold is smaller than the second preset angle threshold, and the first target threshold value is greater than the second target threshold value.

Exemplarily, when the angle between the front of the mobile terminal and the horizontal is greater than 70 degrees, it means that the mobile terminal is basically in a vertical state, and the user may hold the mobile terminal to the ear to answer the phone, even if the strong light environment is close to the proximity sensor. The influence of the value is also small, and the target threshold value at this time can be determined as the second smaller target threshold value.

Step 210 , determine that the corresponding target threshold value of the proximity sensor is the third target threshold value, and perform step 211 .

Optionally, the third target threshold value may be the same as the first target threshold value or the same as the second target threshold value, or may be between the first target threshold value and the second target threshold value. value. When the included angle is greater than or equal to 40 degrees and less than or equal to 70 degrees, the mobile terminal may be in the process of being lifted or lowered, and the approaching state or the moving away state generally does not change, and judgment may not be required. Therefore, this The target threshold value can be the same as the first target threshold value or the same as the second target threshold value, or it can be a value between the first target threshold value and the second target threshold value. Examples are not specifically limited.

Step 211: Control the proximity sensor to determine the proximity state or the distance state based on the target threshold value.

Exemplarily, when it is determined to be in the approaching state, the mobile terminal is controlled to be in a black screen state; when it is determined to be a far away state, the mobile terminal is controlled to be in a bright screen state.

In the control method of the proximity sensor provided by the embodiment of the present application, when it is detected that the ambient light is strong and the user is about to listen to the sound through the earpiece, the attitude information of the mobile terminal is obtained, and the corresponding target threshold value is determined according to the angle between the attitude information and the horizontal plane. , and then control the proximity sensor to determine the approaching state or the distant state according to the target threshold value, which can more reasonably determine the target threshold value corresponding to different attitudes in the strong light environment under the premise of saving power consumption, and accurately determine the proximity state. state and away state.

FIG. 3 is a schematic flowchart of another method for controlling a proximity sensor provided by an embodiment of the present application. As shown in FIG. 3 , the method includes:

Step 301: After the mobile terminal is powered on, if the light intensity value a of the current environment is less than the preset light intensity threshold value A, obtain the current proximity value of the proximity sensor as the preset threshold value M.

Exemplarily, when the mobile terminal is powered on, it is basically in an unblocked state. If the ambient light intensity is not high at this time, the current proximity value can be obtained in time as a preset threshold value for subsequent superimposition with the preset superimposition value. .

Step 302: Acquire attribute information of the current user, and determine a corresponding preset superposition value N according to the attribute information, and record the sum of M and N as the second target threshold value.

Wherein, the N value can be used to represent the influence value of the oil pollution produced by the skin of the face or ear of the current user on the proximity value of the proximity sensor. For example, in the absence of oil pollution, the proximity value is 400, but under oil pollution, the oil pollution may reflect some light back, so the proximity value increases, for example, it can reach 460. In order to eliminate the influence of oil pollution, you can set the preset door On the basis of the limit value M, a preset superposition value N is added to serve as the target threshold value in the erect state.

Step 303: Determine whether the light intensity value b of the current environment is greater than the preset light intensity threshold value B, and if so, perform step 304; otherwise, perform step 303 repeatedly.

Step 304: When it is detected that the earpiece listening event is triggered, the gesture information of the mobile terminal is acquired.

Step 305: Determine the included angle of the front face of the mobile terminal relative to the horizontal plane according to the attitude information.

Step 306: Determine the relationship between the included angle and the first preset angle threshold and the second angle threshold. When the included angle is smaller than the first preset angle threshold, perform step 307; when the included angle is greater than the second preset angle threshold, perform step 307. Step 308 is performed.

Exemplarily, when the included angle is greater than or equal to the first preset angle threshold value and less than or equal to the second preset angle threshold value, the current threshold value of the proximity sensor can be used to determine the approaching state or the away state, that is, it will not be Make changes to the current threshold value.

Step 307 , determine that the corresponding target threshold value of the proximity sensor is the first target threshold value, and execute step 309 .

Step 308 , determine that the corresponding target threshold value of the proximity sensor is the second target threshold value, and perform step 309 .

Step 309 , control the proximity sensor to determine the proximity state or the away state based on the target threshold value.

In the control method of the proximity sensor provided by the embodiment of the present application, when the mobile terminal is powered on, a preset threshold value is determined, and a preset superimposition value affected by oil pollution is determined according to the user attribute information, and the preset threshold value and the preset value are superimposed. The sum of the values is used as the target threshold value corresponding to the standing posture of the mobile terminal. On the basis of considering the influence of the mobile terminal posture on the proximity value, the influence of human skin oil on the proximity value can be further considered, and the threshold of the proximity sensor can be further reasonably determined. value, and accurately determine the approaching state and the distant state.

FIG. 4 is a structural block diagram of a control device for a proximity sensor provided by an embodiment of the present application. The device can be implemented by software and/or hardware, and is generally integrated in a mobile terminal. The proximity sensor can be controlled by executing a control method for the proximity sensor. control. As shown in Figure 4, the device includes:
