Fig. 3 is a schematic process diagram of a light intensity value adjusting method according to an embodiment of the present application, including the following steps:
s301: the method comprises the steps of obtaining a first light intensity value of a light sensor of a calibration terminal under a first light source environment and a second light intensity value under a second light source environment, wherein the first light source environment is different from the second light source environment, and the second light source environment comprises a screen luminous environment.
The method for adjusting the light intensity value provided by the embodiment of the application is applied to a terminal device, and the terminal device may be the terminal device shown in fig. 1 or fig. 2. For example, the terminal device is a calibration terminal, that is, the calibration terminal may adjust its light intensity value. Wherein, a light sensor is integrated in the terminal device, and the light intensity value is used for representing the energy of the light received by the light sensor per unit area. For example, the light sensor may be an off-screen light sensor, and the light sensor may acquire a first light intensity value in a first light source environment and a second light intensity value in a second light source environment.
The first light source environment is different from the second light source environment. The first light source environment and the second light source environment have different ambient light sources and/or different screen-lighting light intensity values. Wherein the screen may be the display screen 132 of fig. 1 described above.
Illustratively, the first light source is ambient only and the screen does not emit light. For example, in the first light source environment, the light intensity value of the ambient light source is the set light intensity value and the screen emits no light. The value of the set light intensity value is not limited, but it is necessary to ensure that when the light intensity value of the calibration terminal is adjusted and the first light intensity values of the calibration terminal and the standard terminal in the first light source environment are obtained, the set light intensity values of the first light source environment are kept consistent, that is, in the first light source environment, the ambient light source with the set light intensity values is used as the standard light source of the calibration terminal and the standard terminal.
Illustratively, only the screen is illuminated but no ambient light source is present under the second ambient light source. For example, in the environment of the second light source, the white backlight level of the screen without the ambient light source is the highest. In particular, implementations without an ambient light source include, but are not limited to, placing the calibration terminal in a dark box; the highest white backlight grade of the screen is the screen display white pixel point of the calibration terminal, and the screen brightness is the highest brightness of the calibration terminal.
FIG. 4 is a schematic diagram of a structure between a photosensor (ALS) and an OLED (organic light-emitting diode) panel with an optical path between the photosensor and the OLED panel, where the optical path refers to a point-to-point logical connection between the photosensor and an optical layer of the OLED panel, and the optical path is associated with an optical path coefficient l a Correspondingly, the light intensity value of light acquired outside the screen is attenuated through the light path, the light intensity value is weakened, and the light paths and light path coefficients of different terminals are possibly different from each other, so that the light intensity values of different terminal devices acquired under the same light source environment when the light reaches the light sensor through different light paths are different, namely, the individual difference exists between different terminal devices; when the OLED screen displays brightness, the OLED screen can generate self-luminescence phenomenon, and the self-luminescence phenomenon and the self-luminescence coefficient l of the screen c Correspondingly, the self-luminescence of the OLED screens of different terminal devices may have luminescence difference, that is, the light intensity values of the screens of different terminal devices are different, resulting in individual difference between different terminal devices; the OLED screen can not completely shade light and transmit light, namely the OLED screen has corresponding light transmission, light transmission and light transmission coefficient l b Correspondingly, the light transmittance coefficient of the screen is used for representing the light transmittance efficiency of the screen, the visual effect of the display screen is influenced, the light intensity value of light acquired outside the screen is attenuated through the OLED screen, the light intensity value is weakened, the light transmittance of the OLED screens of different terminal devices is different, the light intensity values of the light acquired by the different terminal devices under the same light source environment after passing through the different OLED screens are different, and the individual difference exists among the different terminal devices. The embodiments of the present application are therefore mainly directed toOptical path coefficient l a Transmittance of light l b Self-luminous coefficient of c These several factors adjust the light intensity value of the calibration terminal.
If the light intensity value of the ambient light source is the set light intensity value and the screen does not emit light in the first light source environment, the OLED screen does not self-emit light, so that the light emission difference of the OLED screen does not affect the first light intensity value in the first light source environment. Since the ambient light source can reach the optical sensor through the OLED screen and the optical path in the first light source environment, the light transmittance of the screen affects the first light intensity value when the ambient light source penetrates the OLED screen; the light path also affects the first light intensity value when passing through the light path. I.e. in the environment of the first light source, the first light intensity value is related to the light path between the screen of the calibration terminal and the light sensor and/or the transparency of the screen, i.e. the first light intensity value is related to l a And l b It is related. For example, the first light intensity value may satisfy the following formula (1):
X 12 ＝l a2 ×l b2 ×L light source 2 (1)
Wherein, X 12 Representing a first light intensity value, l a2 An optical path coefficient, l, representing the correspondence of the optical path between the screen of the calibration terminal and the optical sensor b2 Light transmittance coefficient, L, corresponding to light transmittance of screen of calibration terminal Light source 2 Representing the light intensity value of a standard light source.
It is assumed that the grade of the white backlight of the ambient-light-free screen is the highest in the environment of the second light source, and no ambient light source penetrates through the screen in the environment of the ambient-light-free screen, so that the light transmittance of the screen does not affect the second light intensity value in the environment of the second light source. When the white backlight level of the screen is the highest, the screen can self-illuminate and has a corresponding light intensity value of the screen, so that the light intensity value of the screen in the second light source environment can affect the second light intensity value; the light intensity value of the screen can only reach the light sensor through the light path, so that the light path also has an influence on the second light intensity value when passing through the light path. I.e. the second light intensity value and the second light source environmentThe light intensity value of the screen at which the light path between the screen of the calibration terminal and the light sensor and/or the white backlight level is highest, i.e. the second light intensity value, is related to a And l c It is relevant. For example, the second light intensity value may satisfy the following formula (2):
X 22 ＝l a2 ×l c2 ×L screen 2 (2)
Wherein, X 22 Representing a second light intensity value, l a2 An optical path coefficient, l, representing the correspondence of the optical path between the screen of the calibration terminal and the optical sensor c2 Self-luminous coefficient, L, corresponding to the light intensity value of the screen of the calibration terminal Screen 2 And a light intensity value representing screen luminescence, wherein the light intensity value of screen luminescence is collected under a second light source environment with the highest white backlight level of the screen of the calibration device.
S302: and acquiring a first fitting value of the standard terminal under the environment of the first light source and the environment of the second light source.
The standard terminal is also called a golden machine, and is generally a standard machine with good performance and accurate measured data.
The first fitting value may be determined according to a fourth light intensity value acquired by the standard terminal in the first light source environment and a fifth light intensity value acquired in the second light source environment. The first light source environment and the second light source environment corresponding to the standard terminal may be considered to be the same as the first light source environment and the second light source environment corresponding to the calibration terminal. For example, if the light intensity value of the ambient light source in the first light source environment corresponding to the calibration terminal is the set light intensity value and the screen does not emit light, the light intensity value of the ambient light source in the first light source environment corresponding to the standard terminal is the set light intensity value and the screen does not emit light, and if the white backlight level of the ambient light source and the screen of the calibration terminal in the second light source environment corresponding to the calibration terminal is the highest, the white backlight level of the ambient light source and the screen of the standard terminal in the second light source environment corresponding to the standard terminal is the highest. Ideally, the light intensity values measured by the calibration terminal and the standard terminal are the same under the same first light source environment and the same second light source environment, but the light intensity values measured by the calibration terminal and the standard terminal are different under the difference existing between the calibration terminal and the standard terminal, so that the standard terminal can be used for calibrating the calibration terminal to correct the difference existing between the calibration terminal and the standard terminal.
In the embodiment of the application, the fitting value of the standard terminal is used for calibrating the calibration equipment, so that the influence of the light transmittance of the screen of the terminal equipment, the light intensity value of the screen and the light path on the light intensity value acquired by the light sensor can be reduced, the terminal equipment is favorable for self-adapting to the light source environment, and the screen brightness can be automatically adjusted according to the light source environment.
S303: and adjusting a third light intensity value acquired by the light sensor of the calibration terminal under the current light source environment according to the first light intensity value, the second light intensity value and the first fitting value.
The current light source environment may be the light source environment in which the user is using the terminal device (i.e. calibrating the terminal), e.g. may comprise both an ambient light source and a screen glow. Generally, the intensity values collected by the light sensor in different light source environments may be different due to the influence of the ambient light source and the screen illumination.
The third light intensity value may be an original light intensity value acquired by the calibration terminal in the current light source environment, and the original light intensity value is adjusted, where the adjusted light intensity value may be considered as a standard light intensity value in the current light source environment, that is, a light intensity value obtained by removing several factors, i.e., a light path of the calibration terminal, a light emission difference of the screen, and a light transmittance. For example, the light intensity value of the standard after the light sensor of the calibration terminal is adjusted may be determined according to the original third light intensity value and the fitting ratio between the calibration terminal and the standard terminal.
According to the embodiment of the application, the third light intensity value acquired by the calibration terminal in the current light source environment is adjusted through the first light intensity value and the second light intensity value acquired by the calibration terminal in different light source environments and the first fitting value of the standard terminal in the same light source environment, so that the accuracy of the light intensity value of the calibration terminal in the current light source environment can be improved, the accuracy of screen brightness adjustment is improved, and user experience is improved.
On the basis of the foregoing embodiment, in the foregoing S303, referring to fig. 5, a process of adjusting a third light intensity value collected by the light sensor of the calibration terminal according to the first light intensity value, the second light intensity value, and the first fitting value includes the following steps:
s501: and determining a second fitting value of the calibration terminal under the first light source environment and the second light source environment according to the first light intensity value and the second light intensity value.
Since the light source environment corresponding to the second fitting value of the calibration terminal is in the first light source environment and the second light source environment, the second fitting value of the calibration terminal can be calculated according to the first light intensity value acquired by the calibration terminal in the first light source environment and the second light intensity value acquired in the second light source environment. In addition, the data accuracy corresponding to the standard terminal is higher, so that the fitting value of the calibration terminal can be calibrated by adopting the fitting value of the standard terminal. For example, the second fitting value may satisfy the following formula (3):
Figure BDA0003908383570000131
wherein Y is Simulation 2 Denotes the second fitting value, X 12 Representing a first light intensity value, X 22 Representing a second light intensity value.
S502: and determining a fitting ratio between the standard terminal and the calibration terminal according to the first fitting value and the second fitting value.
The fit ratio may characterize the difference that exists between the standard terminal and the calibration terminal. For example, the fitting ratio of the standard terminal and the calibration terminal may satisfy the following formula (4):
Figure BDA0003908383570000132
wherein Y is ′ Denotes the fitting ratio, Y, between the standard terminal and the calibration terminal Simulation 1 Represents the first fitting value, Y Simulation 2 Denotes the second fitted value, X 11 Representing a fourth light intensity value, X, collected by the standard terminal in the environment of the first light source 12 Representing a first light intensity value, X 21 Represents a fifth light intensity value, X, collected by the standard terminal in the environment of the second light source 22 Representing a second light intensity value.
S503: and adjusting the third light intensity value collected by the light sensor of the calibration terminal according to the fitting ratio.
Because the fitting ratio can represent the difference between the standard terminal and the calibration terminal, the third light intensity value collected by the light sensor of the calibration terminal can be adjusted according to the fitting ratio so as to correct the difference between the calibration terminal and the standard terminal. For example, the fitting ratio may be used as a weight, and a product between the weight and the third light intensity value is determined as the adjusted light intensity value of the calibration terminal, so as to adjust the third light intensity value collected by the calibration terminal.
On the basis of the foregoing embodiments, the process of acquiring the first fitting value of the standard terminal in the first light source environment and the second light source environment in S302 is shown in fig. 6, and includes the following steps:

The fourth light intensity value and the fifth light intensity value may be collected by a light sensor of the standard terminal.
Assuming that the light intensity value of the ambient light source is the set light intensity value and the screen does not emit light under the environment of the first light source, the fourth light intensity value is related to the light path between the screen and the light sensor of the standard terminal and/or the light transmittance of the screen under the environment of the first light source, i.e. the fourth light intensity value is related to l a And l b It is related. For example, the fourth light intensity value may satisfy the following formula (5):
X 11 ＝l a1 ×l b1 ×L light source 1 (5)
Wherein X 11 Indicating what is acquired by a standard terminal in a first light source environmentFourth light intensity value l a1 An optical path coefficient, l, representing the correspondence of the optical path between the screen of the standard terminal and the optical sensor b1 Light transmittance, L, of a screen corresponding to light transmittance of a standard terminal Light source 1 Representing the light intensity value of a standard light source.
Assuming that the white backlight level of the screen is highest without the ambient light source under the environment of the second light source, the fifth light intensity value is related to the light path between the screen of the standard terminal and the light sensor and/or the light intensity value of the screen when the white backlight level is highest under the environment of the second light source, i.e. the fifth light intensity value is related to l a And l c It is relevant.
For example, the fifth light intensity value may satisfy the following formula (6):
X 21 ＝l a1 ×l c1 ×L screen 1 (6)
Wherein, X 21 Represents a fifth light intensity value, l, collected by the standard terminal in the environment of the second light source a1 An optical path coefficient, l, representing the correspondence of the optical path between the screen of the standard terminal and the optical sensor c1 Self-luminous coefficient, L, corresponding to the light intensity value of the screen representing a standard terminal Screen 1 And a light intensity value representing screen luminescence, wherein the light intensity value of screen luminescence is collected under a second light source environment with the highest white backlight level of a standard device screen.
S602: and determining a first fitting value of the standard terminal according to the fourth light intensity value and the fifth light intensity value.

wherein, C 1 Represents the calibration coefficient of the light sensor of the standard terminal, 385 represents the light intensity value of the standard light source, X 11 Representing a fourth light intensity value.
S702: and determining normal light sensation data of the standard terminal according to the calibration coefficient, the fourth light intensity value and the fifth light intensity value of the light sensor of the standard terminal.
The normal light sensation data is light sensation data influenced by an ambient light source and screen luminescence. The normal light sensation data may satisfy the following formula (9):
Y 1 ＝(l a1 ×l b1 ×X light source 1 +l a1 ×l c1 ×X Screen 1 )×C 1 (9)
Wherein Y is 1 Normal light sensation data, X, representing a standard terminal Light source 1 Representing the light intensity value, X, at the ambient light source (if any) Screen 1 Representing the light intensity value of the glow, if any, on the screen.
Assuming that there is no ambient light source in the second light source environment, the above equation (9) can be expressed as the following equation (10):
Y simulation 1 ＝l a1 ×l c1 ×X Screen 1 ×C 1 (10)
S703: and determining a first fitting value of the standard terminal under the environment of the first light source and the environment of the second light source according to the normal light sensation data of the standard terminal.
Substituting the above equation (7) into equation (10) can yield the following equation (11):
Y pseudo-1 ＝l a1 ×l c1 ×X Screen 1 ×385/X 11 (11)
Light intensity value X due to the environment of the first light source 11 And optical path coefficient l a1 And a light transmittance l b1 On the basis of the above formula (11), therefore, canTo see the first fitting value Y of the standard terminal Simulation 1 And optical path coefficient l a Transmittance of light l b And self-luminous coefficient of screen l c Are related and positively correlated.
Similarly, the second fitting value of the calibration terminal may also be obtained by a processing procedure similar to S701-S703, and the obtained second fitting value Y is processed Simulation 2 Satisfy Y Simulation 2 ＝l a2 ×l c2 ×X Screen 2 ×385/X 12 Second fitting value and optical path coefficient l a Transmittance of light l b And self-luminous coefficient l of screen c Are related and positively correlated.

Specifically, the first fitting relationship between the first fitting value of the standard terminal and the second fitting value of the calibration terminal may be determined according to a ratio of a formula (11) corresponding to the first fitting value of the standard terminal and a formula corresponding to the second fitting value of the calibration terminal.
Due to X Screen 1 、X Screen 2 All represent the luminous intensity value of the screen under the current light source environment, the white backlight grade of the screen under the second light source environment is the highest, and the light intensity values corresponding to the highest white backlight grade of the screen are the same, so that the X of the standard terminal Screen 1 And X of calibration terminal Screen 2 The values of (A) are the same. Therefore, the first fitting relationship between the first fitting value of the standard terminal and the second fitting value of the calibration terminal may satisfy the following formula (12):
