Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 2 is a flowchart of a first method for determining ambient light brightness according to an embodiment of the present disclosure, as shown in fig. 2, and is applied to a terminal including a light sensor and a display screen, where the light sensor is disposed below the display screen, and the method for determining ambient light brightness includes the following steps:
and S11, determining the first ambient light brightness currently detected by the light sensor.
S12, determining display condition information of the display screen, wherein the display condition information comprises: backlight brightness information of the display screen and display content of the display screen.
And S13, correcting the first ambient light brightness according to the display condition information to obtain second ambient light brightness.
In an embodiment of the present disclosure, a terminal device includes: a mobile device and a stationary device; the mobile device includes: a mobile phone, a tablet computer, or a wearable device, etc. The fixed device includes, but is not limited to, a Personal Computer (PC).
The terminal equipment comprises a display screen which can display image frames. Still be provided with light sensor in the terminal, light sensor sets up the below at the display screen, can turn into the signal of telecommunication with the environment light that sees through the display screen to make the terminal can be according to the signal of telecommunication and confirm environment light brightness.
In the case of a full-screen terminal, a light sensor disposed below a display screen detects light transmitted through a space gap between display units to detect ambient light, and a light receiving area shown in fig. 1 is formed by the space gap between the display units.
In step S11, the light sensor in the terminal obtains a first ambient light level by converting the ambient light transmitted through the spatial gap between the display units into an electrical signal.
However, when the light sensor detects the first ambient light brightness, the display brightness of the display screen and the display content on the display screen both affect the collection of the light signal by the light sensor, so that the first ambient light brightness cannot accurately reflect the ambient light brightness.
It should be noted that, among others, the display content on the display screen is presented by applying an electrical signal value (such as a current value or a voltage value) to the light-emitting unit of the display screen based on the terminal, so that the light-emitting unit emits light. Therefore, the display content on the display screen may affect the detection of the first ambient light level.
In step S12, the terminal determines display status information of the display screen, where the display status information includes: backlight brightness information of the display screen and display contents of the display screen. The backlight brightness information of the display screen refers to the display brightness of the display screen. The display content of the display screen comprises at least one of the following: displaying information of different color components of each pixel point in the content; and displaying the information of partial color components of each pixel point in the content. The display content may be a part of the display content on the display screen or may be the whole display content on the display screen.
In step S13, the terminal corrects the first ambient light level to obtain a second ambient light level according to the display condition information.
It can be understood that, in this embodiment, by determining the display condition information and correcting the first ambient light brightness according to the display condition information, the influence of the backlight brightness information and the display content of the display screen on ambient light brightness collection can be reduced, and the accuracy of determining the ambient light brightness is improved. Further, under the same backlight brightness information, as mentioned above, the light emission of the light emitting unit may also affect the collection of the first ambient light brightness; in addition, aiming at different display contents, the light-emitting brightness of the light-emitting unit is different, so that the influence of the display contents is further considered on the basis of the backlight brightness information, and the accuracy of determining the ambient light brightness can be further improved.
It should be noted that in the implementation of the present disclosure, the central processing unit of the terminal may execute steps S12 and S13, or the light sensor in the terminal may execute steps S12 and S13. When steps S12 and S13 are performed by the light sensor in the terminal, the light sensor obtains the display condition information of the display screen from the central processor, and corrects to obtain the second ambient light level. And the light sensor reports the first ambient light brightness to the central processing unit, so that the central processing unit optimizes the operation of the terminal according to the corrected second ambient light brightness.
In one embodiment, step S13 includes:
and the terminal determines a compensation parameter of the first environmental light brightness according to the corresponding relation between the display condition information and the environmental light brightness compensation parameter, and corrects the first environmental light brightness by using the compensation parameter to obtain a second environmental light brightness.
In this embodiment, the terminal may store a corresponding relationship between the display condition information and the ambient light brightness compensation parameter, so that after the current display condition information is determined, the terminal may query and obtain the compensation parameter of the first ambient light brightness according to the corresponding relationship. The correspondence may be stored, for example, in the form of a relationship list.
The first ambient light brightness is corrected by using the compensation parameter, where the correction includes multiplying the first ambient light brightness by the compensation parameter to obtain a second ambient light brightness, or subtracting the compensation parameter from the first ambient light brightness to obtain the second ambient light brightness, and the like.
In one embodiment, the determining the display condition information on the display screen includes:
determining color information of the display content on the display screen;
correcting the first environmental light brightness to obtain a second environmental light brightness according to the display condition information, including:
determining a compensation parameter of the first ambient light brightness according to the corresponding relationship between the backlight brightness information and the color information of the display content and the ambient light brightness compensation parameter;
and correcting the first ambient light brightness by using the compensation parameter to obtain the second ambient light brightness.
In this embodiment, the display condition information on the display screen includes color information of the display content. For example, for a display screen with RGB color mode, the color information of the display content refers to the values corresponding to the red component, the green component and the blue component of each pixel point in the display content, that is, the three primary color information of each pixel point. For the display screen with the RGBW color mode, the color information of the display content refers to values corresponding to a red component, a green component, a blue component and a white component of each pixel point in the display content. And different display contents, wherein the color information of the display contents is different.
In this embodiment, one backlight brightness information and one set of color information correspond to one ambient light brightness compensation parameter.
It should be noted that the color information of the display content is obtained by applying different electrical signal values (such as current values or voltage values) to the light emitting units of the display screen based on the terminal, and emitting light of multiple colors based on the organic light emitting material coated on each light emitting unit or under the action of the color filter, so that the display screen can present the color information of the display content. The color information of the display content is also the embodiment of the light emitting brightness of the light emitting unit. Different color information, substantially corresponding light emitting units have different emitted brightness and thus different influence on the brightness of the surrounding environment, for example, black has less influence on the brightness of the surrounding environment than white.
It can be understood that, in this embodiment, not only the backlight brightness information can embody the brightness of the light emitted by the terminal itself, but also the color information of the display content can embody the brightness of the light emitted by the terminal. In this embodiment, the compensation parameter is determined by combining the color information of the display content with the backlight brightness information, that is, the compensation parameter is determined based on the brightness of the light emitted by the terminal, so that the determination of the compensation parameter can be more effective, and the accuracy of correcting the first ambient light brightness is effectively improved.
In one embodiment, the method further comprises:
determining a target display area on the display screen above a first position according to the first position of the light sensor below the display screen;
the determining color information of the display content on the display screen includes:
and determining color information of the display content in the target display area.
As shown in fig. 1, the light sensor a1 collects the ambient light brightness through a surrounding light-transmitting area a2, so that when the light sensor collects the ambient light brightness, the display condition information of not the whole area of the display screen affects the detection of the ambient light brightness.
Therefore, in this embodiment, the terminal determines the target display area on the display screen above the first position according to the first position of the light sensor below the display screen. The target display area is a part of the display area on the display screen.
For example, fig. 3 is an exemplary view of a coverage of display content, and as shown in fig. 3, the display content is not content in the entire area of the display screen, but is a portion of the display content covering the position of the light sensor.
Therefore, in this embodiment, when determining the color information of the display content, only the color information of the display content within the target display area may also be determined. As mentioned above, the color information is the representation of the luminance of the light emitting unit, so the color information of the display content in the target display area can reflect the luminance information of the light emitting unit in the light receiving area of the light sensor.
It can be understood that, in the embodiment of the present disclosure, the target display area is determined according to the first position where the light sensor is located, and only the color information of the display content in the target display area is obtained, so that on one hand, the calculation amount is reduced, and on the other hand, the influence of the display content in the light receiving area of the light sensor on the detection of the ambient light brightness can be more accurately embodied, and therefore, the accuracy of correcting the first ambient light brightness can be improved.
In one embodiment, the color information of the display content includes: and the color deviation information of the display content refers to information of a color component with the largest average value in different color components contained in the display content.
In this embodiment, for example, the display color includes three color components of red, green, and blue. The average value of each color component in the whole display area or part of the display area of the display screen is counted, and the information of the color component with the maximum average value is used as a part of the display condition information.
As described above, the terminal applies different electrical signal values (such as current values or voltage values) to the light emitting units of the display screen, and emits light of multiple colors based on the organic light emitting materials coated on the light emitting units or under the action of the color filter, so that the display screen can present color information of display contents. The larger the value of the applied electric signal is, the stronger the light of a certain color emitted by the light-emitting unit is, and the more the corresponding color information is presented. Therefore, in the embodiment of the disclosure, the color deviation information can reflect the maximum brightness of the display screen when the display screen displays the content.
It can be understood that, in the embodiment of the present disclosure, the compensation parameter is determined by combining the color deviation information of the display content with the backlight brightness information, so that the influence of the display condition information of the display screen on the detection of the ambient light brightness can be accurately embodied, and the accuracy of the correction of the first ambient light brightness can be improved.
In one embodiment, the determining the display condition information of the display screen includes:
and when the first environment light brightness is smaller than a preset brightness threshold value, determining the display condition information of the display screen.
Experiments show that under the same backlight brightness information, such as the backlight brightness of 600 lux (lux), when the light of the external environment is strong and different display contents are displayed above the light sensor, the difference between the ambient light brightness detected by the data of the light sensor and the actual ambient light brightness is 50 lux; in dim light conditions, the ambient light intensity detected by the light sensor deviates more from the actual ambient light intensity.
It is understood that, for the same backlight brightness information, when the first ambient light brightness is larger, the first ambient light brightness detected by the light sensor may not be much different from the actual ambient light brightness. Therefore, the display condition information of the display screen is determined only when the first ambient light brightness is smaller than the preset brightness threshold, and the necessity of correcting the first ambient light brightness can be improved.
In one embodiment, the method further comprises:
determining whether the display condition information of the display screen changes within a preset time length;
step S13 includes:
and under the condition that the display condition information changes, correcting the first environmental light brightness according to the display condition information to obtain the second environmental light brightness.
In an embodiment of the present disclosure, displaying whether the status information changes includes: whether the backlight brightness information of the display screen changes and/or whether the display content changes. As mentioned above, the backlight brightness information and/or the display content may affect the brightness detection of the light sensor. Therefore, in the case where the display condition information changes, it is necessary to correct the first ambient light luminance according to the display condition information.
It should be noted that, in the embodiment of the present disclosure, whether the display content changes includes whether the color information of the display content changes and also includes whether the biased color of the display content changes.
Illustratively, taking the biased color of the display content as an example, according to experiments, it is found that when the biased color of the display content changes, the error value of the light sensor is larger; when the deviation color information is not transformed, the error value of the light sensor may be relatively small.
It can be understood that, in the case that the display condition information changes, the present disclosure corrects the first ambient light brightness according to the display condition information, on one hand, unnecessary calculation can be reduced to save power consumption; on the other hand, when the display content or the backlight brightness information changes, the detection of the ambient light brightness by the light sensor also changes, so that the correction is performed under the condition that the display content or the backlight brightness information changes, and the accuracy of determining the ambient light brightness can be improved.
In one embodiment, the method further comprises:
and adjusting the backlight brightness of the display screen according to the second ambient light brightness.
As mentioned above, the cpu in the terminal may optimize according to the corrected second ambient light brightness. In this embodiment, after the terminal corrects the first ambient light brightness according to the display condition information of the display screen to obtain the second ambient light brightness, the backlight brightness of the display screen can be adjusted.
For example, when the second ambient light level is high, the backlight brightness of the display screen can be increased; when the second ambient light brightness is very low, the backlight brightness of the display screen can be reduced to adapt to human eyes of a user.
Of course, the contrast of the display content on the display screen can also be adjusted according to the second ambient light brightness. For example, when the second ambient light level is high, the contrast of the content displayed on the display screen is increased to improve the visual experience of the user.
The terminal can adjust the brightness of the flash lamp according to the second ambient light brightness. For example, when the second ambient light level is high, the brightness of the flash that is turned on may be set to be slightly lower to save power consumption; and when the brightness of the second environment is very low, the brightness of the turned-on flash lamp can be set to be higher, so that the user experience is improved.
Fig. 4 is a flowchart illustrating an exemplary method for determining ambient light level according to an embodiment of the disclosure, where as shown in fig. 4, the method for determining ambient light level includes the following steps:
and S21, acquiring the ambient light brightness by the light sensor.
In this implementation, the ambient light level obtained by the light sensor is the first ambient light level.
S22A, the light sensor obtains the backlight value.
In this embodiment, the backlight value obtained by the light sensor, i.e. the backlight brightness information of the display screen, is part of the display condition information of the display screen.
S22B, the light sensor acquires the display color.
In this embodiment, the light sensor obtains the display color, i.e., the color deviation information of the display content on the display screen, and also belongs to a part of the display condition information.
And S23, checking the table by the light sensor to obtain the compensation parameter.
In this embodiment, the light sensor looks up the table to obtain the compensation parameter, that is, the light sensor determines the compensation parameter according to the corresponding relationship between the backlight brightness information and the color information of the display content and the ambient light brightness compensation parameter.
Fig. 5 is a table showing the correspondence between the display condition information and the ambient light brightness compensation parameter in the embodiment of the disclosure, as shown in fig. 5, where one backlight intensity value and one color deviation information correspond to one compensation parameter offset.
The light sensor can obtain the compensation parameter based on the table shown in fig. 5 according to the obtained backlight value and the display color.
And S24, the light sensor corrects the ambient light brightness by using the compensation parameter.
And S25, reporting the corrected ambient light brightness by the light sensor.
In this embodiment, the corrected ambient light level is the second ambient light level.
It can be understood that, in this embodiment, after the light sensor detects the ambient light brightness, the compensation parameter is further obtained according to the obtained backlight value and the display color look-up table, and then the compensation parameter is used to correct the ambient light brightness and report the corrected ambient light brightness, so that the influence of the backlight value and the display color on the ambient light brightness is reduced, and the accuracy of determining the ambient light brightness is improved.
