detailed description

The technical solution in this application will be described below in conjunction with the drawings.

With the rapid development of electronic technology, electronic devices such as mobile phones, tablet computers, notebook computers, televisions, display devices, vehicle-mounted computers, multimedia players, etc. have become more and more popular.

FIG. 1 is a schematic block diagram of an electronic device 100 applied to an embodiment of the present application. As shown in FIG. 1, the electronic device 100 may include: a processor 110, a memory 120, an ambient light sensor 130, a display module 140, a power interface 150, and a display screen 160.

It should be understood that the embodiment of the present application does not specifically limit the display screen 160 of the electronic device 100, and it may be a common liquid crystal display screen, a touch display screen, or a flexible screen.

The ambient light sensor 130 is used to detect the intensity of the external ambient light acting on the display screen 160 of the electronic device 100 to obtain the intensity of the external ambient light.

The display module 140 is used to adjust the initial backlight brightness of the display screen 160 and/or the initial pixel value of the target image to be displayed on the display screen 160.

The memory 120 is used to store at least an operating system, a database, and related program codes executed by the computer.

The processor 110 is configured to obtain the ambient light intensity collected by the ambient light sensor 130. The processor 110 can read relevant program codes executed by the computer from the memory 120 through the bus 170, so that the processor 110 can adjust the initial pixel value of the target image on the display screen 160 by controlling the display module 140.

It should be understood that the bus 170 may be any type of bus such as a peripheral component interconnect standard (PCI) bus or an extended industry standard architecture (EISA) bus. The bus 170 can be divided into an address bus, a data bus, a control bus, and so on. For ease of representation, only one line is used in FIG. 1, but it does not mean that there is only one bus or one type of bus.

The embodiment of the present application does not specifically limit the memory 120. The memory 120 may be a storage unit inside the processor 110, or may be an external storage unit independent of the processor 110, or may also be a component including a storage unit inside the processor 110 and an external storage unit independent of the processor 110 .

The memory 120 may include a read-only memory and a random access memory, and provides instructions and data to the processor 110. A part of the processor 110 may also include a non-volatile random access memory. For example, the processor 110 may also store device type information.

The embodiment of the present application does not specifically limit the type of the processor 110. The processor 110 may be, for example, a central processing unit (CPU), a general-purpose processor, a digital signal processor (digital signal processor, DSP), an application-specific integrated circuit (ASIC), and a field programmable gate. Array (field programmable gate array, FPGA) or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof. It can implement or execute various exemplary logical blocks, modules and circuits described in conjunction with the disclosure of this application. The processor may also be a combination for realizing computing functions, for example, including a combination of one or more microprocessors, a combination of a DSP and a microprocessor, and so on.

The power interface 150 is used to connect to an external power source, and the external power source supplies power to the electronic device 100 through the power interface 150.

In the process of displaying images on the display screen 160 of the electronic device 110, it is faced with a more complicated objective environment, for example, image display effects caused by ambient light. In the case of high ambient light intensity, the image displayed by the electronic device through the display screen will face problems such as loss of detail and color distortion, resulting in a poor user experience.

When the electronic device 100 faces the problem of the image display effect caused by the ambient light, in the prior art, the display screen backlight brightness of the electronic device 100 is adjusted to deal with the larger ambient light intensity, so that the display screen can show a higher intensity. Good image display effect. Specifically, the ambient light intensity can be detected by the ambient light sensor 130 on the electronic device 100, and the backlight brightness of the corresponding display screen can be determined according to the mapping relationship between the ambient light intensity and the backlight brightness of the display screen. For example, when the ambient light intensity is high, the display module 140 is used to increase the display backlight brightness of the electronic device. For another example, when the ambient light intensity is low, the display module 140 reduces the brightness of the display backlight of the electronic device.

However, when the external ambient light intensity is high, since the backlight brightness of the display screen 160 of the electronic device 100 has a certain adjustment range, even if the backlight brightness of the display screen 160 is adjusted to the maximum, there will still be a display screen. The image on the 160 has problems such as color distortion and loss of detail. It is still difficult for human eyes to recognize and see the information on the display screen of the electronic device, and it is difficult to achieve a better image display effect. For another example, the intensity of the ambient light in the outside world is not very high, and the backlight brightness of the display screen 160 is adjusted to the maximum, which will make the display screen 160 in the mode of full backlight. Since the brightness of the backlight of the display screen 160 accounts for a relatively high proportion of the power consumption of the electronic device 100, the full-bright backlight mode will result in greater power consumption.

Therefore, the technical solutions provided by the embodiments of the present application can achieve a better image display effect, and can reduce the power consumption of the electronic device while embodying a better image display effect.

Fig. 2 is a schematic flowchart of a method for adaptively displaying an image provided by an embodiment of the present application. The method shown in FIG. 2 may include steps 210-230, and steps 210-230 will be described in detail below.

Step 210: Obtain the ambient light intensity.

The method of obtaining the ambient light intensity is not specifically limited in the embodiments of the present application. As an example, the ambient light sensor 130 (also called a photoreceptor) installed on the electronic device 100 can be used to sense the light intensity of the current environment.

Step 220: adaptively adjust the initial backlight brightness of the display screen and/or the initial pixel value of the target image to be displayed according to the ambient light intensity.

In the embodiments of the present application, the initial backlight brightness of the display screen and the initial pixel value of the target image to be displayed can be adaptively adjusted at the same time according to the ambient light intensity, so that a better image display effect can be presented on the display screen, and it can also be more effective. Good image display effect while reducing the power consumption of electronic equipment.

In the embodiments of the present application, the initial backlight brightness of the display screen can be adjusted only according to the intensity of the ambient light, or the initial pixel value of the target image can be adjusted only according to the intensity of the ambient light, or the intensity of the ambient light can also be adjusted adaptively at the same time. The size of the initial backlight brightness and the initial pixel value of the adjustment target image.

In some embodiments, when the external ambient light intensity is low, the initial backlight brightness of the display screen can be adjusted preferentially, so that the human eyes can recognize and see clearly the information on the display screen of the electronic device.

It should be understood that a smaller ambient light intensity can be understood as the ambient light intensity is less than the fourth threshold value, and the size of the fourth threshold value can be set by itself, which is not specifically limited in the embodiment of the present application.

In some embodiments, when the external ambient light intensity is high, and the initial backlight brightness of the display screen is adjusted to the mode of full backlight (which can be understood as the maximum backlight brightness of the display screen), there will still be a display screen. In the case of problems such as color distortion and loss of details of the target image to be displayed, the initial pixel value of the target image can be adjusted so that the bright area of the target image is not significantly overexposed, and the human eye can recognize and see clearly on the display of the electronic device Information.

For example, in the case where the external ambient light intensity is greater than the first threshold and less than the second threshold, the initial pixel value of the target image can be adjusted while adjusting the initial backlight brightness of the display screen, so that a better image display can be achieved. Under the premise of the effect, the brightness of the backlight is reduced, thereby reducing the power consumption of the electronic device.

It should be understood that the second threshold is a larger value than the first threshold, and the size of the second threshold can be set by oneself, which is not specifically limited in the embodiment of the present application.

Specifically, in a feasible implementation manner, when the intensity of the ambient light is greater than the first threshold, the initial pixel value of the pixel of the target image is adjusted.

In another feasible implementation manner, when the ambient light intensity is less than the second threshold, the initial pixel value of the pixel of the target image is adjusted.

In another feasible implementation manner, when the intensity of the ambient light is greater than the first threshold and the intensity of the ambient light is less than the second threshold, the initial pixel value of the pixel of the target image is adjusted.

In another feasible implementation manner, when the ambient light intensity is greater than the first threshold and the initial backlight brightness is greater than the third threshold, the initial pixel value of the pixel of the target image is adjusted.

In another feasible implementation manner, when the ambient light intensity is less than the second threshold and the initial backlight brightness is greater than the third threshold, the initial pixel value of the pixel of the target image is adjusted;

In another feasible implementation manner, when the ambient light intensity is greater than the first threshold, the ambient light intensity is less than the second threshold, and the initial backlight brightness is greater than the third threshold, the initial pixel value of the pixel of the target image is performed Adjustment.

It should be understood that a larger ambient light intensity can be understood as the ambient light intensity greater than the third threshold, and the third threshold can be set by itself, which is not specifically limited in the embodiment of the present application.

Step 230: Perform adaptive display of the image brightness of the display screen according to the adjusted backlight brightness and/or the adjusted pixel value.

In this application, the image displayed on the display screen is also referred to as a display image.

The embodiment of the present application may adjust the initial pixel value of the target image based on the brightness curve function. Exemplarily, the brightness curve function may include the first parameter m and the second parameter p.

Specifically, the parameter m can be determined according to the light intensity of the current environment sensed by the ambient light sensor (also called a photoreceptor), and the parameter m is a parameter that changes adaptively according to the current ambient light intensity. The parameter p can be determined according to the average value of the initial pixel values of the pixels at the preset positions of the target image. Among them, the pixel at the predicted position can be all the pixels in the target image, it can also be the pixels in a certain set area, or it can be the pixels obtained by down-sampling the whole frame or the pixels in a certain area. In this regard, the embodiments of this application do not limit this.

In a feasible implementation, the value of the parameter p is the average value of the initial pixel values of all pixels in the target image.

The adjusted pixel value can be determined according to the adjusted parameter m, the parameter p determined by the initial pixel value of the target image, and the initial pixel value of the target image. The specific brightness curve function is as follows:

Among them, L represents the initial pixel value of the target image;

L ₁ represents the adjusted pixel value calculated according to the scene luminance fidelity (SLF) function, that is, the pixel value of the displayed image;

p is the above second parameter;

m is the above-mentioned first parameter;

a, b are constants, used to control the range of the curve expressed by the above formula.

It should be understood that the parameter p and the parameter m can control the shape and degree of curvature of the curve represented by the curve function SLF(L).

Fig. 3 is a schematic diagram of a curve determined according to a curve function provided by an embodiment of the present application. The abscissa of the curve shown in FIG. 3 is used to represent the initial pixel value L of the target image to be displayed, and the ordinate is used to represent the adjusted pixel value L ₁ .

As shown in Figure 3, the relationship between the initial pixel value L and the adjusted pixel value L ₁ will change with the change of the parameter p and the parameter m, that is, the change of the parameter p and the parameter m will cause L and L Between ₁ the curve shape and the degree of bending are variable. The smaller the parameter m,

The larger the output value L will increase. For example, straight line 1 and curve 2 in FIG. 3 are used to represent curves corresponding to different output values L under different values of parameter m. Decrease the value of the parameter m, the mapping relationship of the output value L will change from straight line 1 to curve 2. When the input L remains unchanged, the output value L will increase as the parameter m decreases.

Therefore, the parameter m can be determined adaptively according to the ambient light intensity, and the adjusted pixel value L ₁ should be determined according to the parameter m and the initial pixel value L.

The following describes in more detail the specific implementation process of the image brightness adaptive display method in the embodiment of the present application with reference to FIG. 4. It should be noted that the example in FIG. 4 is only to help those skilled in the art understand the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific numerical values or specific scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or changes based on the example of FIG. 3 given, and such modifications or changes also fall within the scope of the embodiments of the present application.

Fig. 4 is a schematic diagram of a possible adaptive image display method provided by an embodiment of the present application. As an example and not a limitation, the ambient light intensity can be divided into 5 intervals, for example, [0, A ₁ ), [A ₁ , A2), [A ₂ , A ₃ ), [A ₃ , A ₄ ), [ A ₄ , A ₅ ).

For example, in the interval [0, A ₁ ), since the ambient light intensity is small, the initial backlight brightness can be adjusted preferentially, so that the human eyes can recognize and see clearly the information on the display screen of the electronic device. Therefore, the initial backlight brightness can be adjusted to 10%. And the value of the parameter m is set to m ₁ , and the pixel value L _{1 of the} adjusted image is determined according to the parameter m=m ₁ , the aforementioned brightness curve function, and the initial pixel value L.

It should be understood that m ₁ is an initial parameter for adjusting the pixel value, and the embodiment of the present application does not specifically limit the size of the initial parameter.

For another example, in the interval [A ₁ , A ₂ ), since the ambient light intensity is small, the initial backlight brightness can be adjusted preferentially, so that the human eyes can recognize and see clearly the information on the display screen of the electronic device. Therefore, the initial backlight brightness can be increased, and the backlight brightness can be adjusted from 10% to 70%. Relative to the interval [0, A ₁ ), the value of the parameter m can be unchanged, that is, the initial pixel value of the target image to be displayed is not changed.

For another example, in the interval [A ₂ , A ₃ ), since the backlight brightness has been adjusted to 70% in the interval [A ₁ , A ₂ ), as the ambient light intensity increases, you can adjust the initial pixel of the target image Value to achieve a better image display effect. As an example, the initial pixel value of the target image can be increased by reducing the value of the parameter m. By increasing the brightness of the target image on the display, problems such as color distortion and loss of details on the display are avoided. For example, the value of parameter m can be set to

The adjusted pixel value L _{1 is} determined according to the parameter m=m ₂ , the aforementioned brightness curve function, and the initial pixel value L of the target image.

The experimental results show that when the backlight brightness is adjusted to 70%, the image display effect achieved by adjusting the initial pixel value of the target image by the parameter m=m ₂ is the same as the image display effect achieved by only adjusting the backlight brightness to 100%. Therefore, under the premise of ensuring the same image display effect, the power consumption of the electronic device can be reduced by reducing the brightness of the backlight.

For another example, in the interval [A ₃ , A ₄ ), since the ambient light intensity is relatively large, the initial backlight brightness can be adjusted to achieve a better image display effect. For example, the backlight brightness can be adjusted from 70% to 100%.

For another example, in the interval [A ₄ , A ₅ ), since the initial backlight brightness has been adjusted to 100% in the interval [A ₃ , A ₄ ) (backlight full bright mode), if the target image to be displayed on the display is still There are problems such as color distortion and loss of details. You can increase the initial pixel value of the target image by adjusting the value of m to improve the brightness of the target image on the display screen, and avoid image color distortion and loss of details on the display screen. . For example, the value of parameter m can be set to

The pixel value L _{1 of the} adjusted image is determined according to the parameter m=m ₃ , the aforementioned brightness curve function, and the initial pixel value L of the target image.

The experimental results show that when the traditional technology only adjusts the initial backlight brightness to 100%, the target image to be displayed on the display screen has problems such as color distortion and loss of details. In the embodiment of the application, the initial backlight brightness is adjusted to 100%. And after increasing the initial pixel value of the target image, the bright area of the image is not significantly overexposed, and the dark area details are better preserved, so that the human eye can recognize and see clearly the information on the display screen of the electronic device.
