In addition, "and/or" in the specification and the claims means at least one of connected objects, and a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
According to the infrared sensor compensation method provided by the embodiment of the application, the execution main body can be an infrared sensor compensation device, or a control module used for executing the infrared sensor compensation method in the infrared sensor compensation device.
The infrared sensor compensation device in the embodiment of the present application may be a device, or may be a component, an integrated circuit, or a chip in a terminal. The device can be mobile electronic equipment or non-mobile electronic equipment. By way of example, the mobile electronic device may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile electronic device may be a server, a Network Attached Storage (NAS), a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiments of the present application are not particularly limited.
The infrared sensor compensation device in the embodiment of the present application may be a device having an operating system. The operating system may be an Android operating system (Android), an iOS operating system, or other possible operating systems, which is not specifically limited in the embodiments of the present application.
The infrared sensor compensation method, the infrared sensor compensation device, the electronic apparatus, the readable storage medium, and the chip provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an infrared sensor compensation method provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
step 101: acquiring a first infrared value;
step 102: and under the condition that the first infrared value is smaller than a preset infrared value, compensating the infrared sensor.
The infrared sensor can be applied to electronic equipment, for example, the infrared sensor can be applied to a mobile phone and used for shielding a screen in a close range, so that the mobile phone can be effectively prevented from being touched by mistake in a call state.
The infrared sensor may include an emitting end and a receiving end, where the emitting end is an infrared light emitting device (or "infrared LED"), and the receiving end is a light sensing sensor (sensor).
As shown in fig. 2, before the infrared LED operates, the PN junction of the receiving terminal is in an unexcited state, and no electron is attached to the internal hole (trap), so that after the infrared LED operates, it takes a certain time for the internal hole of the PN junction to be filled. Under the state of hole saturation, the PN junction can reach the state of complete pre-charging, and the response speed of the photocurrent can reach the stable state.
When the internal hole of the PN junction of the receiving end of the infrared sensor does not reach the saturation state, the infrared value acquired by the electronic device may be lower than the true infrared value of the infrared sensor, which may cause the update of the infrared dynamic reference to be lower than the true infrared value of the infrared sensor. For the user side, the problem that the call is far away from the non-bright screen or the distance of preventing the false touch is short may occur.
It should be noted that, because a certain measurement error exists, the infrared value acquired by the electronic device generally cannot be completely equal to the real infrared value of the infrared sensor, and the infrared value acquired by the electronic device in the embodiment of the present application is equal to the real infrared value of the infrared sensor, which can be understood as that the absolute value of the difference between the acquired infrared value and the real infrared value is smaller than the preset value.
In view of this, in the embodiment of the present application, in the working process of the infrared sensor, by acquiring the first infrared value, the infrared sensor is compensated when the first infrared value is smaller than the preset infrared value. Therefore, the difference value between the acquired infrared value and the real infrared value can be effectively made up by compensating the infrared sensor, so that the stability of the working performance of the infrared sensor can be improved.
The reason why the internal hole of the PN junction of the receiving end of the infrared sensor does not reach the saturation state mainly comprises the following steps: firstly, infrared components in the environment are less, so that holes in a PN junction can be filled in a certain time; secondly, the emission frequency of the infrared sensor is low, so that after the infrared sensor is started to work, the holes in the PN junction can be filled in within a certain time.
For better understanding of the embodiments of the present application, the following concept is defined and the operation scene of the infrared sensor is divided into a normal operation scene and an abnormal operation scene.
Ambient infrared value: and ADC value corresponding to infrared component in environment collected by the receiving end.
Under-compensated infrared value: under the condition that no infrared component exists in the environment, the infrared value actually acquired by the receiving end is lower than the real infrared value of the infrared sensor due to the problem of the pre-charging time of the PN junction, and the real infrared value of the infrared sensor is also called as the real reflection energy of the infrared LED and is an ADC value corresponding to the real reflection energy of the infrared LED.
Compensation value: the difference between the true infrared value and the under-compensated infrared value.
The current infrared value is: the current infrared value is equal to the real infrared value under the normal working scene of the infrared value actually collected by the receiving end; and under the abnormal working scene, the current infrared value is equal to the under-compensated infrared value.
As shown in fig. 3, in a normal working scenario (3-a), the emission frequency of the infrared sensor is 100ms, or there is an infrared component in the environment, and the current infrared value is equal to the real infrared value. In an abnormal working scene (3-b), the emission frequency of the infrared sensor is 5s, no infrared component exists in the environment, and the current infrared value is lower than the real infrared value.
Because the environment infrared value plays a key role in whether the current infrared value can reflect the real infrared value, the embodiment shown in fig. 4 can be adopted to judge whether the infrared sensor needs to be compensated. As shown in fig. 4, the infrared sensor compensation method includes the following steps:
step 101 a: acquiring an ambient infrared value;
step 102 a: and under the condition that the environment infrared value is smaller than the PN junction saturation response threshold value of the infrared sensor, compensating the infrared sensor.
In this embodiment, whether compensation for the infrared sensor is needed can be determined by the ambient infrared value. Specifically, when the ambient infrared value is smaller than the PN junction saturation response threshold of the infrared sensor, it can be determined that the infrared sensor needs to be compensated, and in this case, the infrared sensor can be compensated. When the ambient infrared value is greater than or equal to the PN junction saturation response threshold of the infrared sensor, it can be determined that compensation for the infrared sensor is not required, and in this case, compensation for the infrared sensor may not be performed.
In the embodiment, whether the infrared sensor needs to be compensated is judged through the environment infrared value, whether the infrared sensor needs to be compensated can be reasonably measured, and a reasonable infrared sensor compensation mechanism is provided.
In the embodiment of the present application, when it is determined that compensation needs to be performed on the infrared sensor, the following embodiment may be performed to compensate the infrared sensor.
As an optional implementation manner, the compensating the infrared sensor includes:
and adjusting the emission power of the infrared sensor from a first emission power to a second emission power according to the environment infrared value, wherein the second emission power is larger than the first emission power.
In this embodiment, the adjusting the emission power of the infrared sensor from the first emission power to the second emission power includes:
adjusting an emission current of the infrared sensor from a first emission current to a second emission current, the second emission current being greater than the first emission current; alternatively, the first and second electrodes may be,
adjusting the emission pulse width of the infrared sensor from a first emission pulse width to a second emission pulse width, wherein the second emission pulse width is larger than the first emission pulse width; alternatively, the first and second electrodes may be,
adjusting the emission period of the infrared sensor from a first emission period to a second emission period, wherein the second emission period is smaller than the first emission period.
Further, the adjusting the transmission power of the infrared sensor from the first transmission power to the second transmission power according to the ambient infrared value includes:
determining a power adjustment value corresponding to the environment infrared value according to a pre-written configuration file;
and adjusting the emission power of the infrared sensor from a first emission power to a second emission power according to the power adjustment value.
The configuration file is written with adjustment logic of the infrared sensor emission power, for example, a power adjustment value corresponding to the ambient infrared value. The configuration file may be written into the infrared sensor in advance, and the adjustment logic of the transmission power of the infrared sensor may be run by a state machine or an MCU (Micro Control Unit) inside the infrared sensor.
The configuration file can be generated through the following steps:
controlling the infrared sensor to work in an infrared-free environment at the first emission frequency and the third emission power, and acquiring a second infrared value of the infrared sensor;
controlling the infrared sensor to work in an infrared-free environment at the second emission frequency and the fourth emission power, and acquiring a third infrared value of the infrared sensor;
under the condition that the difference value of the second infrared value and the third infrared value is larger than or equal to a preset value, adjusting the fourth transmitting power until the difference value of the second infrared value and the third infrared value is smaller than the preset value;
and performing linear regression on the adjusted fourth transmitting power and the environment infrared value to generate the configuration file.
As an example, a theoretical model for linear regression of the emitted power of an infrared sensor with ambient infrared values can be seen in fig. 5.
In fig. 5, a function a is a normal operating mode curve of the infrared sensor, a function B is an existing abnormal operating mode curve, and a function C is an operating mode curve for dynamically adjusting the transmission power of the infrared sensor according to the ambient infrared value. The point a can be understood as a threshold of an ambient infrared value measured by a laboratory environment under the condition of constant transmission power, the point b is the transmission power in an abnormal working scene, and the point a and the point b can be obtained by debugging.
In the function C, the configuration gear of the transmission power of the infrared sensor is related to the configuration supported by the actual infrared sensor, and the specific configuration method and the number of the gear are not described in the embodiment of the present application.
Due to the fact that the infrared sensors are good in consistency, a set of dynamic power configuration can be fitted and applied to each infrared sensor, and configuration files can be generated for different monomers.
In this embodiment, adjusting the emission power of the infrared sensor may be considered as compensating at a hardware end, and may be considered as integrating two new photosensitive sensors as a receiving end. As an example, as shown in fig. 6, in a normal operation scene, the emission power of the infrared LED does not need to be adjusted, the MCU and the photosensitive sensor may be integrated into a new photosensitive sensor, and in an abnormal operation scene, the emission power of the infrared LED needs to be adjusted, and the MCU, the photosensitive sensor and the infrared LED may be integrated into another new photosensitive sensor.
In the embodiment, the emission power of the infrared sensor is dynamically adjusted through the infrared value of the current environment, so that the infrared value acquired by the electronic equipment is equal to the real infrared value of the infrared sensor, the difference between the acquired infrared value and the real infrared value can be effectively made up, and the stability of the working performance of the infrared sensor can be improved.
As another optional embodiment, the compensating the infrared sensor includes:
calculating a compensation value according to the fourth infrared value and the environment infrared value; the fourth infrared value is the infrared value of the infrared sensor in the on state;
determining a sum of the fourth infrared value and the compensation value as an infrared value of the infrared sensor.
In the embodiment, the compensation value is calculated through the infrared value of the current environment, the compensation of the infrared sensor can be realized on the software algorithm level, the infrared value acquired by the electronic equipment can be equal to the real infrared value of the infrared sensor, so that the difference between the acquired infrared value and the real infrared value can be effectively compensated, and the stability of the working performance of the infrared sensor can be improved.
In the embodiment of the application, by compensating the infrared sensor, the infrared sensor can be enabled to obtain the infrared value matched with the real infrared value no matter the infrared sensor works in the normal working scene or the abnormal working scene shown in fig. 3.
In order to increase the screen occupation ratio of electronic devices, under-screen sensor technology, such as under-screen infrared sensor technology, is used. In the technology of the infrared sensor under the screen, the infrared emission is generally closed when the screen is on, and the infrared emission is opened when the screen is off. In order to reduce the damage of infrared emission to the screen, the emission interval of delayed infrared emission (i.e. the infrared emission frequency is reduced) is usually adopted in the breath screen state, so that the PN junction at the receiving end of the infrared sensor needs a certain time to be precharged to reach a stable working state.
The emission frequencies of the infrared sensors can be distinguished according to the use scene of the infrared sensors. In a normal use scenario (corresponding to a normal working scenario), the emission interval of the infrared emission does not need to be delayed, and at this time, the emission frequency of the infrared sensor may be emitted once every 100 milliseconds, for example, while for a use scenario (corresponding to an abnormal working scenario) under the screen, the emission interval of the infrared emission needs to be delayed in the screen resting state, and at this time, the emission frequency of the infrared sensor may be emitted once every 5 seconds, for example.
In view of this, the embodiment of the present application can be used to solve, but not limited to, the technical problem that the infrared value acquired by the electronic device is lower than the real infrared value of the infrared sensor due to the delayed emission interval of the infrared emission of the off-screen infrared sensor, that is, the embodiment of the present application can be applied to the above abnormal working scenario and also applied to the above normal working scenario.
It should be noted that, in the embodiment of the present application, various optional implementations of the infrared sensor compensation method may be implemented in combination with each other, or may be implemented separately, and the present application is not limited thereto.
In the embodiment of the application, by acquiring the first infrared value, the infrared sensor is compensated when the first infrared value is smaller than the preset infrared value. Therefore, the difference value between the acquired infrared value and the real infrared value can be effectively made up by compensating the infrared sensor, so that the stability of the working performance of the infrared sensor can be improved.
It should be noted that, in the infrared sensor compensation method provided in the embodiment of the present application, the execution main body may be an infrared sensor compensation device, or a control module in the infrared sensor compensation device for executing the infrared sensor compensation method. In the embodiment of the present application, an infrared sensor compensation method executed by an infrared sensor compensation device is taken as an example, and the infrared sensor compensation device provided in the embodiment of the present application is described.
