Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The light sensor operates on the principle of the photoelectric effect. The photoelectric effect refers to a phenomenon that some special substances can convert light energy into electric energy after absorbing light, and the photoelectric effect can be divided into an external photoelectric effect and an internal photoelectric effect. The external photoelectric effect refers to the effect that electrons can be emitted outwards from the inside of a substance under the irradiation of light rays to generate electric power, and a photoelectric tube and a photomultiplier tube are original elements manufactured based on the external photoelectric effect. Accordingly, the internal photoelectric effect occurs inside a substance, and when light is irradiated onto the substance, the resistivity inside the substance is changed, thereby generating electromotive force. Photoelectric elements such as photoresistors and photocells are manufactured based on the internal photoelectric effect.
A light sensor in a mobile terminal in the prior art belongs to an ambient light sensor and mainly comprises a light projector and a light receiver. The white point near the front camera acts as a lens, which focuses the light in the environment and transmits it to the light receiver via the light projector. The light receiver can convert various optical signals into corresponding electric signals according to the photoelectric effect, and then the electric signals are further processed into various switches and control actions so as to realize the photosensitive regulation of the mobile terminal.
However, after the mobile terminal is used for a long time, the precision of the internal light sensor is reduced, the illumination value of the mobile terminal is changed, and the terminal cannot adjust the illumination value, so that a terminal user needs to disassemble and overhaul at a maintenance point to recover the precision of the light sensor, and the operation is complex.
The embodiment of the application provides a method and a device for reporting an illumination value, a storage medium and a mobile terminal.
Referring to fig. 1, fig. 1 is a schematic flow chart of an illumination value reporting method according to an embodiment of the present application, where the illumination value reporting method is applied to a mobile terminal, the mobile terminal includes a light sensor, the light sensor includes a plurality of light sensing channels, and the mobile terminal may be any intelligent electronic device with a mobile communication function, such as a smart phone, a tablet computer, and a notebook computer. The specific process of the method for reporting an illumination value provided by this embodiment may be as follows:
s101, when the light sensor needs to report data, a first illumination component of each photosensitive channel at the previous moment and a second illumination component of each photosensitive channel at the current moment are obtained.
It should be noted that the processor may determine whether data reporting is required for the light sensor by determining whether a drop event occurs in the terminal.
For example, before the step S101, the following steps may be included:
acquiring two motion accelerations of the mobile terminal at any adjacent time;
when the difference value between the two motion acceleration values is larger than a preset difference value, determining that the light sensor needs to report data;
and when the difference value between the two motion acceleration values is smaller than a preset difference value, determining that the light sensor does not need to report data.
In the embodiment, two motion accelerations of the mobile terminal at any adjacent time can be obtained through the acceleration sensor inside the terminal, when the mobile terminal falls, the motion acceleration of the terminal can be increased instantaneously, and the acceleration sensor inside the terminal obtains the motion acceleration of the mobile terminal by measuring the inertia force applied to the terminal and calculating according to the Newton's second law.
It is easy to understand that this acceleration sensor includes capacitanc acceleration sensor, inductance type acceleration sensor, strain gauge acceleration sensor, piezoresistive acceleration sensor and piezoelectric type acceleration sensor, for preventing the misdetection, multiple acceleration sensor can be chooseed for use at the terminal, and when the acceleration difference value is greater than the quantity of presetting the acceleration sensor of difference value at adjacent moment, then confirm that light sensor needs to carry out data report.
In addition, the processor may report data of the light sensor at set intervals, where the set interval may be three days, one week, one month, or the like.
For example, before the step S101, the following steps may be included:
when the mobile terminal is detected to be started, timing is started;
and when the timing duration reaches the preset duration, determining that the optical sensor needs to report data, and returning to the step of executing the starting timing.
In this embodiment, the terminal is clocked by an internal crystal oscillator that includes one or more combinations of a non-temperature compensated crystal oscillator, a temperature compensated crystal oscillator (TCXO), a voltage controlled crystal oscillator (VCXO), an oven controlled crystal oscillator (OCXO), and a digitized/μ p compensated crystal oscillator (DCXO/MCXO).
S102, determining target collection frequency of the light sensor according to the first illumination component and the second illumination component, and collecting a third illumination component of each photosensitive channel according to the target collection frequency.
Specifically, the step S102 may specifically include:
calculating a difference value between the first illumination component and the second illumination component corresponding to each photosensitive channel;
when the difference value is larger than a preset threshold value, determining the corresponding photosensitive channel as an abnormal channel;
when the number of the abnormal channels is larger than the preset number, acquiring the acquisition frequency of the light sensor at the current moment;
and adjusting the acquisition frequency by the target multiple to obtain the target acquisition frequency.
In this embodiment, when the processor determines that the light sensor needs to report data, the illumination component of the photosensitive channel of the light sensor at adjacent time may only slightly change, and does not affect the precision of the light sensor, in this case, the processor does not need to adjust the light sensor; in addition, when the difference value of the illumination components of the photosensitive channels at adjacent moments exceeds a preset threshold value, the photosensitive channels are determined as abnormal channels, but if the number of the abnormal channels does not exceed the preset number, the photosensitive capacity of the light sensor is not changed greatly, and in this case, the processor does not need to adjust the light sensor; only when the quantity of unusual passageway has exceeded predetermined quantity, light sensor's photosensitive ability just can receive very big influence, under this condition, the treater just need adjust light sensor, and later, the treater adjusts light sensor's collection frequency according to the target multiple, makes light sensor can gather more data in the same time.
It should be noted that the larger the acquisition frequency of the light sensor is, the larger the power consumption generated by the terminal is, and in order to reduce the power consumption of the terminal, the target multiple may be set in a gradient manner.
For example, before the step of "adjusting the acquisition frequency by a target multiple", the method may further include:
acquiring the abnormal grade corresponding to the number of the abnormal channels;
and acquiring a preset multiple corresponding to the abnormal grade as a target multiple.
In this embodiment, the number of the abnormal channels may be divided into abnormal levels, where the larger the number of the abnormal channels, the higher the abnormal level is, the larger the preset multiple corresponding to the abnormal level is, and each abnormal level may correspond to a certain number of abnormal channels, for example, when the number of the abnormal channels is 2 to 3, the abnormal level is m 1; when the number of exception channels is 4-5, the exception level is m2, and so on.
And S103, determining a reported illumination value according to the third illumination component, and reporting the reported illumination value.
Specifically, the step S103 may specifically include:
calculating the average value of the third illumination components corresponding to each photosensitive channel under the target acquisition frequency;
and carrying out weighted calculation on the average values corresponding to all the photosensitive channels to obtain a reported illumination value.
In this embodiment, when the processor calculates the average value of the third illumination component corresponding to each photosensitive channel at the target acquisition frequency, in order to make the error smaller, the value of the third illumination component may be compared first, a number having a larger difference with most of the numerical values is removed, then the remaining numerical values are averaged, and when performing weighting calculation on the average values corresponding to all the photosensitive channels, the weight of each photosensitive channel may be determined according to the abnormal level first, and then the weighting calculation is performed.
From the above, it can be seen that, different from the prior art, the present application provides an illumination value reporting method, an apparatus, a storage medium and a mobile terminal, where the illumination value reporting method is applied to the mobile terminal, where the mobile terminal includes a light sensor, the light sensor includes a plurality of photosensitive channels, and when it is determined that the light sensor needs to report data, the illumination value reporting method obtains a first illumination component of each photosensitive channel at a previous time and a second illumination component of each photosensitive channel at a current time, determines a target collection frequency of the light sensor according to the first illumination component and the second illumination component, collects a third illumination component of each photosensitive channel at the target collection frequency, and then determines a reported illumination value according to the third illumination component, and reports the reported illumination value, so that the mobile terminal can adjust the illumination value of the light sensor in real time, the problem that the precision of the light sensor is reduced due to long-time use is avoided, and the precision and the reliability of light detection are improved.
Referring to fig. 2, fig. 2 is another schematic flow chart of an illumination value reporting method according to an embodiment of the present disclosure, where the illumination value reporting method is applied to a mobile terminal, the mobile terminal includes a light sensor, the light sensor includes a plurality of light sensing channels, and the mobile terminal may be any intelligent electronic device with a mobile communication function, such as a smart phone, a tablet computer, and a notebook computer. The specific process of the method for reporting an illumination value provided by this embodiment may be as follows:
s201, two motion accelerations of the mobile terminal at any adjacent time are obtained.
In this embodiment, the processor may determine whether data reporting is required for the light sensor of the terminal by judging whether a drop event occurs in the terminal, specifically, the processor may obtain two motion accelerations of the mobile terminal at any adjacent time through an acceleration sensor inside the terminal, when the mobile terminal has a drop event, the motion acceleration of the terminal may be instantaneously increased, and the acceleration sensor inside the terminal obtains the motion acceleration of the mobile terminal by measuring an inertial force applied to the terminal and calculating according to a newton second law.
S202, when the difference value between the two motion acceleration values is larger than a preset difference value, it is determined that the light sensor needs to report data.
In this embodiment, the acceleration sensor includes a capacitive acceleration sensor, an inductive acceleration sensor, a strain acceleration sensor, a piezoresistive acceleration sensor, and a piezoelectric acceleration sensor, and in order to prevent misdetection, the terminal may select multiple acceleration sensors, and when the number of acceleration sensors whose acceleration difference values at adjacent times are greater than a preset difference value is greater than the preset number of sensors, it is determined that the light sensor needs to report data.
In addition, the processor may report data of the light sensor at set intervals, where the set interval may be three days, one week, one month, or the like.
For example, before the step S201, the method may further include:
when the mobile terminal is detected to be started, timing is started;
and when the timing duration reaches the preset duration, determining that the optical sensor needs to report data, and returning to the step of executing the starting timing.
In this embodiment, the terminal is clocked by an internal crystal oscillator that includes one or more combinations of a non-temperature compensated crystal oscillator, a temperature compensated crystal oscillator (TCXO), a voltage controlled crystal oscillator (VCXO), an oven controlled crystal oscillator (OCXO), and a digitized/μ p compensated crystal oscillator (DCXO/MCXO).
S203, acquiring a first illumination component of each photosensitive channel at the last moment and a second illumination component of each photosensitive channel at the current moment.
In this embodiment, when the processor determines that the speed of the mobile terminal is no longer changed, the first illumination component of each light-sensing channel at the previous time and the second illumination component of each light-sensing channel at the current time are obtained, for example, referring to fig. 3, the motion acceleration of the mobile phone is increased instantaneously at the moment the mobile phone falls, the speed is increased all the time from the beginning of falling to the landing, and after landing, the speed becomes zero and remains unchanged, and then the first illumination components a1, b1, c1 and d1 at the previous time and the second illumination components a2, b2, c2 and d2 at the current time of the mobile phone light sensor 4 are obtained.
And S204, calculating a difference value between the first illumination component and the second illumination component corresponding to each photosensitive channel.
S205, when the difference value is larger than a preset threshold value, determining that the corresponding photosensitive channel is an abnormal channel.
In this embodiment, when the processor determines that the light sensor needs to report data, the illumination component of the photosensitive channel of the light sensor at adjacent time may only slightly change, and the precision of the light sensor is not affected. For example, referring to fig. 3, the photosensitive channels a and b are determined as abnormal channels because the differences between a1 and a2, b1 and b2 are greater than the predetermined threshold x, and the differences between c1 and c2, and between d1 and d2 are less than the predetermined threshold x, so the photosensitive channels c and d are determined as normal channels.
S206, when the number of the abnormal channels is larger than the preset number, acquiring the abnormal grade corresponding to the number of the abnormal channels and the acquisition frequency of the light sensor at the current moment.
In this embodiment, if the number of the abnormal channels does not exceed the preset number, the light sensing capability of the light sensor is not changed too much, and in this case, the processor does not need to adjust the light sensor; the light sensing capability of the light sensor is only greatly affected if the number of abnormal channels exceeds a predetermined number, in which case the light sensor needs to be adjusted by the processor.
S207, acquiring a preset multiple corresponding to the abnormal grade as a target multiple, and adjusting the acquisition frequency according to the target multiple to obtain the target acquisition frequency.
In this embodiment, the number of the abnormal channels may be divided into abnormal levels, where the larger the number of the abnormal channels, the higher the abnormal level is, the larger the preset multiple corresponding to the abnormal level is, and each abnormal level may correspond to a certain number of abnormal channels, for example, when the number of the abnormal channels is 2 to 3, the abnormal level is m 1; when the number of exception channels is 4-5, the exception level is m2, and so on. For example, referring to fig. 3, the number of abnormal channels is 2, the corresponding abnormal level is m1, and the preset multiple corresponding to the abnormal level m1 is 5, so that the acquisition frequency f is adjusted to 5 f.
And S208, collecting a third illumination component of each photosensitive channel at a target collection frequency.
In this embodiment, the processor adjusts the collection frequency of the light sensor according to the target multiple, so that the light sensor can collect more data in the same time.
S209, calculating the average value of the third illumination component corresponding to each photosensitive channel under the target acquisition frequency.
In this embodiment, when the processor calculates the average value of the third illumination component corresponding to each photosensitive channel at the target acquisition frequency, in order to make the error smaller, the value of the third illumination component may be compared first, a number that is different from most of the values is removed, and then the remaining values are averaged.
S210, carrying out weighted calculation on the average values corresponding to all the photosensitive channels to obtain a reported illumination value, and reporting the reported illumination value.
In this embodiment, when performing the weighting calculation on the average values corresponding to all the photosensitive channels, the weight of each photosensitive channel may be determined according to the abnormal level, and then the weighting calculation may be performed. For example, referring to fig. 3, the mobile phone collects and calculates data of four channels of the light sensor at the target collection frequency of 5f to obtain and report the reported illumination value P, so that the accuracy of the light sensor returns to the normal value.
And S211, when the difference value between the two motion acceleration values is smaller than a preset difference value, determining that the light ray sensor does not need to report data.
Referring to fig. 4, fig. 4 is a schematic structural diagram of an illumination value reporting apparatus according to an embodiment of the present disclosure, where the illumination value reporting method is applied to a mobile terminal, the mobile terminal includes a light sensor, the light sensor includes a plurality of light sensing channels, and the mobile terminal may be any intelligent electronic device with a mobile communication function, such as a smart phone, a tablet computer, and a notebook computer.

acquiring abnormal grades corresponding to the number of abnormal channels before adjusting the acquisition frequency by the target multiple;
and acquiring a preset multiple corresponding to the abnormal grade as a target multiple.
In this embodiment, the number of the abnormal channels may be divided into abnormal levels, where the larger the number of the abnormal channels, the higher the abnormal level is, the larger the preset multiple corresponding to the abnormal level is, and each abnormal level may correspond to a certain number of abnormal channels, for example, when the number of the abnormal channels is 2 to 3, the abnormal level is m 1; when the number of exception channels is 4-5, the exception level is m2, and so on.
