All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/" generally means a relationship in which the associated object is an "or" before and after.
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 application can be a device, and also can be a component, an integrated circuit or a chip in a terminal. The device may be a mobile electronic device or a non-mobile electronic device. By way of example, the mobile electronic device may be a cell phone, tablet computer, notebook computer, palm computer, vehicle-mounted electronic device, wearable device, ultra-mobile personal computer (ultra-mobile personal computer, UMPC), netbook or personal digital assistant (personal digital assistant, PDA), etc., and the non-mobile electronic device may be a server, network attached storage (Network Attached Storage, NAS), personal computer (personal computer, PC), television (TV), teller machine or self-service machine, etc., and the embodiments of the present application are not limited in particular.
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, an iOS operating system, or other possible operating systems, which are not specifically limited in the embodiments of the present application.
The infrared sensor compensation method, the infrared sensor compensation device, the electronic equipment, the readable storage medium and the chip provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Fig. 1 is a flowchart of an infrared sensor compensation method according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step 101: acquiring a first infrared value;
step 102: and compensating the infrared sensor under the condition that the first infrared value is smaller than a preset infrared value.
The infrared sensor can be applied to electronic equipment, for example, the infrared sensor can be applied to a mobile phone, and the infrared sensor is used for shielding a screen at a short distance, so that the mobile phone can effectively prevent false touch in a call state.
The infrared sensor may include a transmitting end and a receiving end, the transmitting 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 is operated, the PN junction at the receiving end is in an unexcited state, and no electron is attached to the internal hole (trap), so that a certain time is required for filling the internal hole of the PN junction after the infrared LED is turned on. Under the state of hole saturation, the PN junction can reach the pre-charge state, and the response speed of the photocurrent can reach the stable state.
When the hole in the PN junction of the receiving end of the infrared sensor does not reach a saturated state, the infrared value acquired by the electronic equipment may be lower than the real infrared value of the infrared sensor, and the updating of the infrared dynamic reference may be caused to be lower than the real infrared value of the infrared sensor. For the user end, the problems that the call is far away from the non-bright screen or the anti-false touch distance is close can occur.
It should be noted that, because of a certain measurement error, the infrared value collected by the electronic device is generally not completely equal to the real infrared value of the infrared sensor, and the infrared value collected by the electronic device in the embodiment of the application is equal to the real infrared value of the infrared sensor, which can be understood that the absolute value of the difference between the collected infrared value and the real infrared value is smaller than the preset value.
In view of this, in the embodiment of the present application, during the operation 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 between the collected infrared value and the real infrared value can be effectively compensated by compensating the infrared sensor, so that the stability of the working performance of the infrared sensor can be improved.
The reasons why the hole in the PN junction of the receiving end of the infrared sensor does not reach the saturated state mainly comprise: firstly, the infrared components in the environment are less, so that holes in the 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, holes in the PN junction can be filled with the holes in a certain time.
For better understanding of the embodiments of the present application, the following concepts are defined and the operation scenario of the infrared sensor is divided into a normal operation scenario and an abnormal operation scenario.
Ambient infrared value: ADC values corresponding to infrared components in the environment collected by the receiving end.
Under-compensated infrared values: under the condition that no infrared component exists in the environment, the infrared value actually collected by the receiving end is lower than the real infrared value of the infrared sensor due to the problem of PN junction pre-charging time, 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 undershot infrared value.
Current infrared value: the receiving end actually collects the infrared value, and under a normal working scene, the current infrared value is equal to the real infrared value; under abnormal working scene, the current infrared value is equal to the undershot infrared value.
As shown in fig. 3, in the normal operation scenario (3-a), the emission frequency of the infrared sensor is 100ms, or an infrared component exists 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.
Since the environmental infrared value plays a key role in whether the current infrared value can reflect the real infrared value, the embodiment of the application may adopt the implementation shown in fig. 4 to determine whether the infrared sensor needs to be compensated. As shown in fig. 4, the infrared sensor compensation method includes the steps of:
In this embodiment, it may be determined whether the infrared sensor needs to be compensated 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 may be determined that the infrared sensor needs to be compensated, in which case the infrared sensor may be compensated. When the ambient infrared value is greater than or equal to the PN junction saturation response threshold of the infrared sensor, it may be determined that no compensation is required for the infrared sensor, in which case no compensation may be performed for the infrared sensor.
In the embodiment, whether the infrared sensor needs to be compensated is judged through the environmental infrared value, whether the infrared sensor needs to be compensated can be reasonably measured, and a reasonable infrared sensor compensation mechanism is provided.
In this embodiment of the present application, in the case where it is determined that the infrared sensor needs to be compensated, the following implementation may be adopted to compensate the infrared sensor.
As an optional implementation manner, the compensating the infrared sensor includes:
and adjusting the transmitting power of the infrared sensor from a first transmitting power to a second transmitting power according to the environmental infrared value, wherein the second transmitting power is larger than the first transmitting 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; or alternatively, the process may be performed,
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; or alternatively, the process may be performed,
and 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 transmitting power of the infrared sensor from the first transmitting power to the second transmitting power according to the environmental infrared value includes:
determining a power adjustment value corresponding to the environmental infrared value according to a pre-written configuration file;
and adjusting the transmitting power of the infrared sensor from the first transmitting power to the second transmitting power according to the power adjusting value.
The configuration file is written with power adjustment logic of the transmitting power of the infrared sensor, for example, a power adjustment value corresponding to the environmental infrared value. The configuration file may be pre-written to the inside of the infrared sensor and the adjustment logic of the infrared sensor transmit power is run by a state machine or MCU (Micro Control Unit ) inside the infrared sensor.
The configuration file may be generated by the following steps:
controlling the infrared sensor to work in an infrared-free environment at the first transmitting frequency and the third transmitting 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;
adjusting the fourth transmitting power until the difference between the second infrared value and the third infrared value is smaller than the preset value under the condition that the difference between the second infrared value and the third infrared value is larger than or equal to the preset value;
and linearly regressing the adjusted fourth transmitting power and the environmental infrared value to generate the configuration file.
As an example, a theoretical model of linear regression of the emitted power of the infrared sensor with the ambient infrared value can be seen in fig. 5.
In fig. 5, the function a is a normal operation mode curve of the infrared sensor, the function B is an existing abnormal operation mode curve, and the function C is an operation mode curve for dynamically adjusting the emission power of the infrared sensor according to the environmental infrared value. The point a can be understood as a threshold of an environmental infrared value under the condition of constant transmitting power through laboratory environmental measurement, the point b is the transmitting power under an abnormal working scene, and the points a and b can be obtained through debugging.
In the function C, the configuration gear of the transmitting power of the infrared sensor is related to the configuration supported by the actual infrared sensor, and a specific configuration method and the number of gears are not described in the embodiment of the application.
Because the infrared sensors have good consistency, a set of dynamic power configuration can be fitted to each infrared sensor, and configuration files can be generated aiming at different monomers.
In this embodiment, adjusting the emission power of the infrared sensor may be regarded as compensating at the hardware end, and may be regarded as integrating two new photosensitive sensors as the receiving end. As an example, as shown in fig. 6, in a normal operation scenario, 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 scenario, 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 collected by the electronic equipment is equal to the real infrared value of the infrared sensor, the difference between the collected 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.
As another optional embodiment, the compensating the infrared sensor includes:
calculating a compensation value according to the fourth infrared value and the environmental infrared value; the fourth infrared value is an infrared value of the infrared sensor in an on state;
and determining the sum of the fourth infrared value and the compensation value as the 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 collected by the electronic equipment can be equal to the real infrared value of the infrared sensor, the difference between the collected 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 this embodiment of the present application, by compensating for the infrared sensor, the obtained infrared value of the infrared sensor can be matched with the actual infrared value, regardless of whether the infrared sensor works in the normal working scene or the abnormal working scene shown in fig. 3.
To increase the screen duty cycle of electronic devices, an off-screen sensor technology, such as an off-screen infrared sensor technology, is applied. In the under-screen infrared sensor technology, the infrared emission is generally turned off when the screen is on, and the infrared emission is turned on when the screen is off. In order to reduce the damage of infrared emission to a screen, an emission interval of delayed infrared emission (i.e. an infrared emission frequency is reduced) is generally adopted in a screen-extinguishing state, so that a PN junction of a receiving end of the infrared sensor needs to be pre-charged for a certain time 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 infrared emission does not need to be delayed, at this time, the emission frequency of the infrared sensor may be, for example, once every 100 milliseconds, and in a screen-off state, for a use scenario (corresponding to an abnormal working scenario), the emission interval of infrared emission needs to be delayed, at this time, the emission frequency of the infrared sensor may be, for example, once every 5 seconds.
In view of this, the embodiment of the application can be used for solving, but is not limited to solving, the technical problem that the infrared value acquired by the electronic device due to the delay of the emission interval of the infrared emission of the infrared sensor under the screen is lower than the real infrared value of the infrared sensor, that is, the embodiment of the application can be applied to the abnormal working scene as described above, and also can be applied to the normal working scene as described above.
It should be noted that, the various optional implementations of the method for compensating the infrared sensor in the embodiments of the present application may be implemented in combination with each other or may be implemented separately, which is not limited to this application.
In the embodiment of the application, the first infrared value is obtained, and the infrared sensor is compensated under the condition that the first infrared value is smaller than a preset infrared value. Therefore, the difference between the collected infrared value and the real infrared value can be effectively compensated 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 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 application, an infrared sensor compensation device executes an infrared sensor compensation method as an example, and the infrared sensor compensation device provided in the embodiment of the application is described.
