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 invention.
An embodiment of the present invention provides an ambient light detection method, which is applied to a mobile terminal, where the mobile terminal includes a first photosensor disposed on a display screen and a second photosensor disposed outside the display screen, as shown in fig. 1, and the method includes:
The mobile terminal needs to acquire initial data of ambient light acquired by the first photosensitive sensor in the current state, wherein the first photosensitive sensor is arranged on the display screen, and the first photosensitive sensor can be ensured to be synchronous with a visual angle of a user when the mobile terminal is normally used. The first photosensitive sensor and the second photosensitive sensor are arranged in the structural member made of the same material, and the second photosensitive sensor is arranged outside the display screen. Wherein, the luminousness of the apron material that the second photosensitive sensor top set up is more stable than the luminousness of the apron material that first photosensitive sensor top set up, and consequently the stability that sets up the sampling environment that the position corresponds of second photosensitive sensor is superior to the stability of first photosensitive sensor sampling environment, and then can realize obtaining predetermined environment light calibration data through second photosensitive sensor for the realization is to the calibration of first photosensitive sensor.
And 102, adjusting initial data of the ambient light according to preset ambient light calibration data to obtain actual data of the ambient light in the current state.
After acquiring the initial data of the ambient light collected by the first photosensitive sensor in the current state and detecting that the light calibration function is started, the initial data of the ambient light can be adjusted according to the preset ambient light calibration data, and the actual data of the ambient light in the current state can be obtained after adjustment.
The preset ambient light calibration data can be acquired through the second photosensitive sensor arranged outside the display screen, the initial data of the ambient light acquired by the first photosensitive sensor is calibrated through the preset ambient light calibration data, and the accuracy of the data acquired by the first photosensitive sensor can be guaranteed.
According to the embodiment of the invention, the initial data of the ambient light collected by the first photosensitive sensor arranged on the display screen in the current state needs to be acquired, and after the initial data of the ambient light is acquired, the initial data of the ambient light is calibrated according to the preset ambient light calibration data, so that the accuracy of the data acquired by the first photosensitive sensor is ensured, and the effectiveness of backlight regulation of the mobile terminal is further ensured.
In an embodiment of the present invention, before the step of acquiring initial data of the ambient light in the current state collected by the first photosensitive sensor, the method further includes: and acquiring preset ambient light calibration data.
Before the initial data of the ambient light in the current state is acquired by using the first photosensitive sensor arranged on the display screen, the preset ambient light calibration data can be acquired by using the second photosensitive sensor arranged outside the display screen, so that the first photosensitive sensor is calibrated by using the second photosensitive sensor.
Wherein, the step of obtaining preset ambient light calibration data comprises:
when detecting that a second photosensitive sensor of the mobile terminal faces a preset direction, acquiring first data of ambient light acquired by the second photosensitive sensor; when the change of the orientation of the second photosensitive sensor is detected, acquiring the time difference between the orientation of the first photosensitive sensor in the preset direction and the orientation change of the second photosensitive sensor; if the time difference is smaller than or equal to a preset time threshold, setting the first ambient light data as preset ambient light calibration data; wherein the first light sensitive sensor collects initial data of ambient light when facing a preset direction.
Before acquiring the preset calibration data of the ambient light, a preset direction needs to be determined, where the preset direction may be a direction of the opposite light source. After the preset direction is determined, the orientation of a second photosensitive sensor arranged outside the display screen is detected, when the second photosensitive sensor faces the preset direction, first data of ambient light collected by the second photosensitive sensor can be acquired, and the acquired first data of the ambient light is stored.
If a change in orientation of the second light sensitive sensor is detected, a first moment in time at which the change in orientation of the second light sensitive sensor occurs needs to be recorded. When the orientation of the second photosensitive sensor is changed and the first photosensitive sensor is detected to face the preset direction, recording a second moment when the first photosensitive sensor faces the preset direction, then acquiring a difference value between the second moment and the second moment, comparing the acquired difference value between the second moment and the first moment with a preset time threshold value, and when the time threshold value between the second moment and the first moment is smaller than or equal to the preset time threshold value, setting the first ambient light data as preset ambient light calibration data.
Because the time value of the mobile terminal from the change of the second photosensitive sensor towards the preset direction to the change of the first photosensitive sensor towards the preset direction is smaller than the preset time threshold, the corresponding time of the change process can be determined to be shorter, and the light environment states of the first photosensitive sensor and the second photosensitive sensor are the same.
The second photosensitive sensor faces to the preset direction, and when the first data of the ambient light are collected, the first data of the plurality of ambient lights in the current state can be obtained, then the average value is obtained, the obtained average value is stored and serves as preset ambient light calibration data, and the accuracy of the preset ambient light calibration data can be improved through the mode.
When the first photosensitive sensor faces the preset direction, the initial data of the ambient light is collected, that is, the initial data of the ambient light in the current state collected by the first photosensitive sensor is the corresponding ambient light data when the first photosensitive sensor faces the preset direction.
In the embodiment of the present invention, when detecting that the second photosensor of the mobile terminal faces the preset direction, the method further includes:
recording the placing state and/or the gravity acceleration component of the mobile terminal;
the step of obtaining the time difference between the orientation of the first photosensor in the preset direction and the orientation of the second photosensor when detecting the change of the orientation of the second photosensor includes:
when the placing state and/or the gravity acceleration component change of the mobile terminal is detected, determining that the orientation of the second photosensitive sensor changes; when the changed placing state of the mobile terminal meets a first preset condition and/or the changed gravitational acceleration component of the mobile terminal meets a second preset condition, determining that the first photosensitive sensor faces a preset direction, and acquiring a time difference value.
When the second photosensitive sensor of the mobile terminal faces the preset direction, at least one of the current placing state and the gravity acceleration component of the mobile terminal can be recorded, and the current placing state and the at least one of the gravity acceleration component of the mobile terminal can be recorded to be used as a comparison reference for judging whether the state of the mobile terminal changes or not.
Wherein the process of obtaining the time difference between the orientation of the first photosensor in the preset direction and the change in orientation of the second photosensor is: when the second photosensitive sensor of the mobile terminal faces the preset direction, after at least one of the current placing state and the gravity acceleration component of the mobile terminal is recorded, if the placing state and/or the gravity acceleration component of the mobile terminal is detected to be changed, the change of the orientation of the second photosensitive sensor can be determined, and at the moment, the first moment is recorded.
When the placing state of the mobile terminal after being changed meets a first preset condition and/or the gravity acceleration component of the mobile terminal after being changed meets a second preset condition is detected, the direction of the first photosensitive sensor towards the preset direction can be determined, the second moment is recorded at the moment, and the difference value between the second moment and the first moment is determined to be the time difference value between the direction of the first photosensitive sensor towards the preset direction and the direction of the second photosensitive sensor.
The following describes a movement track of the mobile terminal from the second photosensitive sensor facing the preset direction to the first photosensitive sensor facing the preset direction. Because the resultant force direction of the mobile terminal in the motion process is vertical downwards all the time, the gravity acceleration sensor on the mobile terminal can be used for calculating the gravity acceleration in each direction on the screen, so that the included angle between the mobile terminal and the vertical surface can be calculated, and the motion change process of the mobile terminal can be known by monitoring the change of the included angle.
On the other hand, the rotation angle within time can be calculated through the gyroscope, so that the motion track of the mobile terminal can be further known through the rotation angle after the gravity acceleration sensor is used for calculating the included angle between the initial position of the mobile terminal and the vertical plane.
When the second photosensitive sensor of the mobile terminal is detected to face the preset direction and the first data of the ambient light collected by the second photosensitive sensor is obtained, the current gravity acceleration component of the mobile terminal is recorded. When the gravity acceleration component of the mobile terminal is detected to meet a second preset condition within a preset time interval, it can be determined that the first photosensitive sensor of the current mobile terminal faces a preset direction, and at the moment, the first photosensitive sensor can acquire initial data of ambient light.
When the second photosensitive sensor of the mobile terminal is detected to face the preset direction and the first data of the ambient light collected by the second photosensitive sensor is acquired, the current placing state of the mobile terminal is recorded. When the placing state of the mobile terminal is detected to meet a first preset condition within a preset time interval, the first photosensitive sensor of the current mobile terminal can be determined to face a preset direction, and at the moment, the first photosensitive sensor can collect initial data of ambient light.
When the second photosensitive sensor of the mobile terminal is detected to face the preset direction and the first data of the ambient light collected by the second photosensitive sensor is acquired, the current placing state and the gravity acceleration component of the mobile terminal can be recorded. When the placing state of the mobile terminal is detected to meet a first preset condition and the gravity acceleration component of the mobile terminal meets a second preset condition within a preset time interval, it can be determined that the first photosensitive sensor of the current mobile terminal faces a preset direction, and at the moment, the first photosensitive sensor can collect initial data of ambient light.
In the embodiment of the invention, the arrangement position of the second photosensitive sensor is not influenced by the interference source, and the stability of the sampling environment corresponding to the second photosensitive sensor is better than that of the first photosensitive sensor. The sampling environment includes, but is not limited to, the interference of the interference source to the device sampling changes with aging of the device as the usage time increases, and the like.
In the embodiment of the present invention, after obtaining the actual data of the ambient light in the current state, the method further includes:
and carrying out backlight adjustment on a display screen of the mobile terminal according to the actual data of the ambient light in the current state.
After the actual data of the ambient light in the current state is determined, the backlight adjustment of the mobile terminal can be performed according to the actual data of the ambient light in the current state, and the effectiveness of the backlight adjustment is ensured on the basis of the data accuracy of the photosensitive device.
In the embodiment of the invention, the initial data of the ambient light in the current state, which is acquired by the first photosensitive sensor arranged on the display screen of the mobile terminal, is acquired, the initial data of the ambient light is adjusted according to the preset ambient light calibration data, and the actual data of the ambient light in the current state is acquired, so that the accuracy of the data acquired by the first photosensitive sensor can be ensured, and the effectiveness of backlight adjustment of the mobile terminal is further ensured.
It should be noted that the first photosensor and the second photosensor may be located on two different end faces of the mobile terminal, and when the two end faces respectively face the preset direction within a time threshold that is less than or equal to the preset time threshold, it may be determined that the first photosensor and the second photosensor are in the same ambient light state, and at this time, the second photosensor may be used to calibrate the first photosensor.
The aim of the embodiment of the invention is to ensure backlight adjustment, and the backlight adjustment is mainly to enable a user to see the display content of a display screen of the mobile terminal clearly in environments with different brightness, so that the first photosensitive sensor is arranged below a front glass cover plate of the mobile terminal, the actual data of the ambient light in the current state is acquired by using the first photosensitive sensor, and the actual data is used as a main data source of the backlight adjustment, so that the synchronization with the visual angle of the user can be kept. The technical scheme of the invention is explained in detail below by taking the example that the first photosensitive sensor is arranged below the front glass cover plate of the mobile terminal, the second photosensitive sensor is arranged at the top of the mobile terminal, and the end face where the second photosensitive sensor is arranged is vertical to the end face where the first photosensitive sensor is arranged.
The positions of the first photosensitive sensor and the second photosensitive sensor are shown in fig. 2, the first photosensitive sensor a is positioned on the front side of the mobile terminal and below the glass cover plate; an opening is formed in the top of the mobile terminal, the second photosensitive sensor B is arranged in the opening, and a transparent cover plate is arranged on the opening.
The sampling environment of the second photosensitive sensor is stable, the accuracy of data can be guaranteed, and due to structural limitation, the data of the second photosensitive sensor has angular deviation with the visual angle of a user and cannot be used as a source of backlight adjustment, and the data of the second photosensitive sensor is used as a data source of auxiliary calibration of the first photosensitive sensor.
It should be noted that, by disposing the first photosensitive sensor below the front glass cover plate of the mobile terminal, the sampling environment of the first photosensitive sensor may change due to aging of surrounding devices, where the sampling environment changes include, but are not limited to: the material of the glass cover plate is aged in the using process, so that the light transmittance is changed, the transmission of the spectrum is influenced, the light transmittance is changed, the old calibration coefficient is not matched with the current sampling environment, and the calibration is needed to be carried out again to compensate the deviation; interference sources can exist around the first photosensitive sensor, interference of the interference sources on device data can change to different degrees along with the use time, and the caused interference amount is variable along with the change of the time, so that the data of the first photosensitive sensor is deviated.
Along with the change of the sampling environment of the first photosensitive sensor, the precision loss of the acquired data of the first photosensitive sensor occurs, and at this time, the second photosensitive sensor which is positioned on other end faces of the mobile terminal and used as auxiliary equipment can be used for calibrating the data. In embodiments of the present invention, the second photosensor is required to remain stationary in the sampling environment, and the second photosensor is used to perform data calibration on the first photosensor. Wherein the fixed sampling environment of the second photosensitive sensor can be understood as: no interference source exists around the second photosensitive sensor, and/or the light transmittance of the cover plate above the second photosensitive sensor is kept stable when the second photosensitive sensor collects data.
The whole process of the embodiment of the invention is shown in fig. 3:
When detecting whether the mobile terminal is in a vertical state, the mobile terminal can be detected through a gravity acceleration sensor arranged in the mobile terminal, and when the gravity acceleration components on all coordinate axes of the mobile terminal are first preset values corresponding to all coordinate axes, the state of the mobile terminal is determined to be in the vertical state. When the mobile terminal is in a vertical state, the second photosensitive sensor faces upward to the light source, at the moment, the orientation of the second photosensitive sensor is a preset direction, and first data of ambient light collected by the second photosensitive sensor can be acquired.
And 303, acquiring initial data of the ambient light collected by the first photosensitive sensor when the mobile terminal is detected to be switched from the vertical state to the horizontal state within a preset time.

When the state change of the mobile terminal is detected, the placing state of the mobile terminal and/or the change condition of the gravity acceleration component can be detected within the preset time. And when the change of the placing state of the mobile terminal is detected, a gyroscope can be adopted for calculation. The preset time is set to meet the condition that the ambient light of the two photosensitive sensors is consistent, and therefore the accuracy of calibration is ensured.
The first data of the ambient light read to the second photosensor in the vertical direction can be regarded as the actual value of the current ambient light source and used as the preset ambient light calibration data.
