Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

With the continuous development of smart terminal technology, the brightness of the backlight on the electronic device can be adjusted according to the brightness of the ambient light. Specifically, the electronic device adjusts the backlight brightness of the display screen according to the backlight adjustment curve between the ambient light brightness and the backlight brightness. Generally, the backlight adjustment curve is obtained through debugging based on the fact that the current display image is a white image (in other words, the gray value of the current display image is 255). That is, no matter what display screen is displayed on the electronic device, as long as the brightness of the ambient light remains unchanged, the display screen of the electronic device adjusted based on the backlight adjustment curve is at the same brightness of the backlight. Therefore, if the display screen displays different display parameters under the same ambient light brightness, that is, the display screen is under the same backlight brightness at this time, the display effect of the display screen under some display parameters is not enough. Clear, affecting the normal viewing of the user.

Therefore, in order to solve this problem, a display screen adjustment method is proposed in the embodiment of the present application, aiming at the situation that different display screens are displayed on the display screen, the display parameters of the current display screen on the display screen are obtained, and it is judged whether the display parameters meet the preset requirements. brightness adjustment conditions. If the display parameter satisfies the preset brightness adjustment condition, the target backlight brightness of the display screen is determined according to the display parameter of the currently displayed image. In this way, the determined target backlight brightness can correspond to the display parameters of the current display screen. Finally, based on the target backlight brightness, the current backlight brightness of the display screen determined according to the ambient light brightness is adjusted to adjust to a suitable backlight brightness for different display images, which can improve the definition of different display images and improve the display effect.

Fig. 1 is an application scene diagram of a method for adjusting a display screen in an embodiment. As shown in Figure 1, the application environment includes an electronic device 120, the electronic device 120 obtains the display parameters of the current display screen on the display screen; if the display parameters meet the preset brightness adjustment conditions, then according to the display parameters of the current display screen Determine the target backlight brightness of the display screen; adjust the current backlight brightness of the display screen based on the target backlight brightness; the current backlight brightness is the backlight brightness of the display screen determined according to the ambient light brightness. Here, the electronic device 120 may be a mobile phone, a tablet computer, a PDA (Personal Digital Assistant, a personal digital assistant), a wearable device (smart bracelet, smart watch, smart glasses, smart gloves, smart socks, smart belt, etc.), a smart home and other terminal equipment.

Fig. 2 is a flow chart of a method for adjusting a display screen in an embodiment. The method for adjusting the display screen in this embodiment is described by taking the electronic device 120 running on the electronic device 120 in FIG. 1 as an example. The display screen adjustment method includes:

Step 202, acquiring the display parameters of the currently displayed image on the display screen.

Wherein, the display parameters of the currently displayed image include display parameters in different color spaces. Specifically, it may be a display parameter of RGB (red, green, blue) color space, HSV (hue, saturation, value) color space or YUV color space, which is not limited in this application. Among them, HSV (hue, saturation, value) in HSV color space represents hue, saturation and brightness respectively; in YUV color space, "Y" represents brightness (Luminance, Luma), "U" represents chroma, and "V " means concentration.

The electronic device obtains the display parameters of the current display screen on the display screen, and specifically can obtain the RGB value of the current display screen in the RGB color space, or can obtain at least one of the hue, saturation, and brightness of the current display screen in the HSV color space, Or at least one of the brightness, chroma, and concentration of the current display image in the YUV color space may be obtained.

Step 204, if the display parameter satisfies the preset brightness adjustment condition, then determine the target backlight brightness of the display screen according to the display parameter of the currently displayed image.

After acquiring the display parameters of the currently displayed image on the display screen, the electronic device judges whether the display parameters meet a preset brightness adjustment condition. If the display parameter satisfies the preset brightness adjustment condition, the target backlight brightness of the display screen is determined according to the display parameter of the currently displayed image.

The brightness adjustment condition here refers to judging whether the display parameter is lower than the preset display parameter threshold. Among them, the preset display parameter threshold for a certain display parameter is based on the fact that under the same backlight brightness, if the display parameter of the display screen is lower than a certain parameter threshold, the displayed display effect is not clear enough, which affects the normal viewing of the user. . Therefore, the parameter threshold is set as the preset display parameter threshold of the display parameter. And for different display parameters, the corresponding preset display parameter thresholds may be the same or different, which is not limited in this application.

Specifically, if the display parameter satisfies the preset brightness adjustment condition, the target backlight brightness of the display screen is determined according to the display parameter of the currently displayed image. Because the display parameter satisfies the preset brightness adjustment condition, it means that the display effect of the currently displayed picture on the display screen under the current backlight brightness does not meet the user's requirements. Therefore, it is necessary to adjust the backlight brightness of the display screen. Specifically, the target backlight brightness of the display screen can be specifically determined based on the display parameters of the current display screen.

Step 206, adjust the current backlight brightness of the display screen based on the target backlight brightness; the current backlight brightness is the backlight brightness of the display screen determined according to the ambient light brightness.

After the electronic device specifically determines the target backlight brightness of the display screen according to the display parameters of the current display screen, it can adjust the current backlight brightness of the display screen based on the target backlight brightness. Specifically, the current backlight brightness of the display screen may be increased based on the target backlight brightness. Wherein, the current backlight brightness of the display screen may be a preset fixed backlight brightness on the electronic device, or a backlight brightness automatically determined by the electronic device according to ambient light brightness, which is not limited in this application.

In the embodiment of the present application, for the case where different display pictures are displayed on the display screen, the display parameters of the current display picture on the display screen are obtained, and it is judged whether the display parameters meet the preset brightness adjustment conditions. If the display parameter satisfies the preset brightness adjustment condition, the target backlight brightness of the display screen is determined according to the display parameter of the currently displayed image. In this way, the determined target backlight brightness can correspond to the display parameters of the current display screen. Finally, based on the target backlight brightness, the current backlight brightness of the display screen determined according to the ambient light brightness is adjusted to adjust to a suitable backlight brightness for different display images, which can improve the definition of different display images and improve the display effect.

In one embodiment, the display parameters include grayscale values; the acquisition of display parameters of the currently displayed picture on the display screen includes:

Taking a screenshot of the current display screen on the display screen to obtain a target image corresponding to the current display screen;

The gray value of the target image is identified to obtain the gray value of the currently displayed image.

Specifically, if the display parameters include grayscale values, when the electronic device obtains the display parameters of the current display screen on the display screen, first, it takes a screenshot of the current display screen on the display screen to obtain a target image corresponding to the current display screen. The target image corresponding to the current display screen can be quickly obtained by taking a screenshot, because the target image has the same display parameters as the current display screen, so subsequent recognition of the target image achieves the effect of recognizing the current display screen. And the gray value recognition of the target image can be realized only by using the corresponding software recognition algorithm, without additional hardware equipment.

Secondly, the gray value of the target image is identified to obtain the gray value of the currently displayed image. When identifying the gray value of the target image, specifically, the target image may be firstly identified to obtain the RGB values of the target image in the RGB color space. Based on the RGB value of the target image in the RGB color space, the gray value of the target image is calculated, and finally, the gray value of the current display screen is obtained based on the gray value of the target image.

In the embodiment of the present application, when acquiring the display parameters of the current display screen on the display screen, it includes: taking a screenshot of the current display screen on the display screen to obtain the target image corresponding to the current display screen; Value identification to get the gray value of the current display screen. The target image corresponding to the current display screen can be quickly obtained by taking a screenshot, because the target image has the same display parameters as the current display screen, so subsequent recognition of the target image achieves the effect of recognizing the current display screen. And the gray value recognition of the target image can be realized only by using the corresponding software recognition algorithm, without additional hardware equipment. It is convenient to subsequently judge whether the display parameters meet the preset brightness adjustment conditions. If the display parameters meet the preset brightness adjustment conditions, the target backlight brightness of the display screen is determined according to the display parameters of the current display screen, and then the backlight adjustment is performed. Therefore, the efficiency of the method for adjusting the display screen is improved, and the cost is reduced.

In one embodiment, the gray value identification of the target image is performed to obtain the gray value of the currently displayed image, including:

Carrying out the gray value identification of the target image to obtain the gray value of each pixel of the target image;

The average value of grayscale values of all pixels on the target image is obtained as the grayscale value of the currently displayed image.

Specifically, a screenshot is taken of the current display screen on the display screen to obtain a target image corresponding to the current display screen. When performing grayscale value identification on the target image to obtain the grayscale value of the current display screen, it includes performing grayscale value identification on the target image to obtain the grayscale value of each pixel of the target image; obtaining the target image The average value of the gray values of all pixels on the image is used as the gray value Gray of the currently displayed image.

Wherein, when performing gray value recognition on the target image, specifically, the target image may be firstly recognized to obtain the RGB value of each pixel of the target image in the RGB color space. Then calculate the gray value of the pixel for the RGB value of each pixel. Finally, the average value of the gray values of all pixels on the target image is calculated as the gray value of the currently displayed image.

In the embodiment of the present application, when performing grayscale value recognition on the target image to obtain the grayscale value of the current display screen, it includes performing grayscale value recognition on the target image to obtain the grayscale value of each pixel of the target image. grayscale value; obtain the average value of the grayscale values of all pixels on the target image as the grayscale value of the current display screen. The gray value recognition of the target image can be realized only by using the corresponding software recognition algorithm, without additional hardware equipment. It is convenient to subsequently judge whether the display parameters meet the preset brightness adjustment conditions. If the display parameters meet the preset brightness adjustment conditions, the target backlight brightness of the display screen is determined according to the display parameters of the current display screen, and then the backlight adjustment is performed. Therefore, the efficiency of the method for adjusting the display screen is improved, and the cost is reduced.

In one embodiment, step 202, if the display parameters meet the preset brightness adjustment conditions, then determine the target backlight brightness of the display screen according to the display parameters of the current display screen, including:

If the gray value of the currently displayed image is less than the preset gray value threshold, then calculate the adjustment parameter according to the gray value of the currently displayed image;

Based on the adjustment parameter and the current backlight brightness of the display screen, the target backlight brightness of the display screen is determined.

Specifically, it is judged whether the grayscale value of the currently displayed picture is less than the preset grayscale value threshold, and if the grayscale value of the currently displayed picture is less than the preset grayscale value threshold, the adjustment parameter is calculated according to the grayscale value of the currently displayed picture . Wherein, the adjustment parameter may be an adjustment value or an adjustment ratio, which is not limited in this application. Since the backlight adjustment curves are all based on the gray value of the current display screen being 255, the backlight adjustment curves are obtained through debugging. Therefore, if different display images are displayed under the same backlight brightness, it is obvious that the display effects seen by the user are not the same. Especially when the grayscale value of the currently displayed image is much lower than 255, the user may not be able to clearly see the currently displayed image under the current backlight brightness.

Therefore, a preset gray value threshold is set, and the preset gray value threshold may be obtained based on multiple experiments. Specifically, under different backlight brightnesses, the grayscale value thresholds of the displayed images that the user can see clearly may be different. For example, under high backlight brightness, the set gray value threshold is relatively low; correspondingly, under low back light brightness, the set gray value threshold is high.

In one case, if the current backlight brightness at this time is 400 nit, the preset grayscale value threshold under the backlight brightness is 200. Then, judge whether the grayscale value of the current display screen is less than 200, if so, calculate the adjustment ratio according to the grayscale value of the current display screen, and determine the target backlight of the display screen based on the adjustment ratio and the current backlight brightness of the display screen brightness.

Wherein, the adjustment ratio rate is calculated according to the gray value of the currently displayed picture, for example, rate=1-Gray/255. Wherein, Gray is the gray value of the currently displayed image. For example, if the grayscale value of the currently displayed image is 180, then rate=1-180/255 at this time is approximately equal to 0.3. And it stipulates that the adjustment ratio of the backlight brightness adjustment based on the gray value cannot exceed 0.5. Therefore, the adjusted adjustment ratio calculated at this time is 0.3. Then, based on the adjustment ratio and the current backlight brightness of the display screen, the target backlight brightness of the display screen can be determined. For example, target backlight brightness=current backlight brightness*(1+0.3), that is, target backlight brightness=400nit*(1+0.3)=520nit. If the calculated adjustment ratio exceeds 0.5, the maximum adjustment ratio can only be 0.5 because it is stipulated that the adjustment ratio for adjusting the brightness of the backlight based on the gray value cannot exceed 0.5.

In another case, after the adjustment ratio is calculated according to the grayscale value of the current display screen, and based on the adjustment ratio and the current backlight brightness of the display screen, the target backlight brightness of the display screen is determined to backlight the display screen. After brightness adjustment. Under the premise that the ambient light remains unchanged, when adjusting the backlight of the subsequent display screen, it is not only necessary to judge whether the gray value of the current display screen is less than the preset gray value threshold, but also to further judge the gray value of the current display screen. Whether the difference between the gray value average values of the preset number of frame display screens before the current display screen is smaller than the preset difference threshold. Or it is further determined whether the change range between the gray value of the current display picture and the gray value average value of the preset number of frame display pictures before the current display picture is smaller than a preset change range threshold. If yes, the brightness of the backlight of the currently displayed image may not be adjusted temporarily. Because if the grayscale value of the currently displayed image is less than the preset difference threshold, it means that the grayscale value of the currently displayed image does not change much compared with the previous displayed image, so the adjustment of the backlight brightness may not be performed to ensure the brightness of the currently displayed image. While displaying the effect, avoid frequently adjusting the brightness of the backlight to cause waste of system resources. The preset number here may not be specifically limited.

As shown in Figure 3, a display screen adjustment method is provided, including:

Step 302, taking a screenshot of the current display screen on the display screen to obtain a target image corresponding to the current display screen;

Step 304, performing gray value identification on the target image to obtain the gray value of each pixel of the target image;

Step 306, obtaining the average value of the grayscale values of all pixels on the target image as the grayscale value of the current display image;

Step 308, judging whether the gray value of the currently displayed image is less than the preset gray value threshold; if so, proceed to step 310; if not, proceed to step 316;

Step 310, calculating adjustment parameters according to the gray value of the currently displayed image;

Step 312, based on the adjustment parameter and the current backlight brightness of the display screen, determine the target backlight brightness of the display screen;

Step 314, adjusting the current backlight brightness of the display screen based on the target backlight brightness.

Step 316, maintaining the current backlight brightness of the display screen.

In the embodiment of the present application, when determining the target backlight brightness of the display screen according to the display parameters of the current display screen, it includes: if the gray value of the current display screen is less than the preset gray value threshold, Calculating an adjustment parameter based on the gray value of the gray value; determining the target backlight brightness of the display screen based on the adjustment parameter and the current backlight brightness of the display screen. Since the backlight adjustment curves are all based on the gray value of the current display screen being 255, the backlight adjustment curves are obtained through debugging. Therefore, if different display images are displayed under the same backlight brightness, it is obvious that the display effects seen by the user are not the same. Especially when the grayscale value of the currently displayed image is much lower than 255, the user may not be able to clearly see the currently displayed image under the current backlight brightness. Therefore, when adjusting the brightness of the backlight based on the display parameters of the currently displayed image, the adjustment of the brightness of the backlight is performed under the condition that the grayscale value of the currently displayed image is smaller than the preset grayscale value threshold. It can be realized that the display screens of different display parameters can be adjusted to a suitable backlight brightness, and the definition of different display screens can be improved, and the display effect can be improved. On the contrary, without adjusting the brightness of the backlight, the consumption of system resources can also be reduced.

In one embodiment, as shown in FIG. 4 , a method for adjusting a display screen is provided, including:

Step 202, obtaining the display parameters of the current display screen on the display screen;

Step 204, if the display parameters meet the preset brightness adjustment conditions, then determine the target backlight brightness of the display screen according to the display parameters of the current display screen;

Step 206, adjust the current backlight brightness of the display screen based on the target backlight brightness; the method also includes:

Step 208, if the current ambient light brightness is greater than the preset ambient light brightness, obtain the color saturation of the currently displayed image.

Firstly, the display parameters of the currently displayed picture on the display screen are obtained, and if the display parameters meet the preset brightness adjustment conditions, then the target backlight brightness of the display screen is determined according to the display parameters of the currently displayed picture. The current backlight brightness of the display screen is adjusted based on the target backlight brightness. Secondly, in this embodiment, for the situation that the current ambient light brightness is greater than the preset ambient light brightness, the color saturation of the display picture at the next moment is adjusted based on the current ambient light brightness.

Specifically, for the situation that the current ambient light brightness is greater than the preset ambient light brightness, the color saturation of the display picture at the next moment is adjusted based on the current ambient light brightness. First, it is judged whether the current ambient light brightness is greater than the preset ambient light brightness. Here, the preset ambient light brightness refers to the ambient light brightness (High-brightness-Model, HBM) in the high-brightness mode, which generally includes the ambient light brightness higher than 10000 lux. Generally, such ambient brightness will appear when the user is outdoors under the sunlight. At this time, due to the influence of sunlight and reflection, the color saturation of the display screen on the electronic device will be relatively low, which will affect the viewing effect of the user.

Secondly, if the current ambient light brightness is greater than the preset ambient light brightness, the color saturation of the currently displayed image is obtained. Wherein, the color saturation is a display parameter in the HSV (hue, saturation, value) color space, also referred to as saturation. Saturation S (saturation) indicates how close a color is to a spectral color. A color that can be seen as the result of mixing a certain spectral color with white. Among them, the larger the proportion of spectral color, the higher the degree of color close to spectral color, and the higher the saturation of color. The saturation is high, and the color is deep and vivid. The white light component of the spectral color is 0, and the saturation reaches the highest. The saturation S usually ranges from 0% to 100%, and the larger the value of the saturation S is, the more saturated the color is.

When obtaining the color saturation of the currently displayed image, an average color saturation of the entire currently displayed image may be obtained.

Step 210, judging whether the color saturation of the currently displayed image is smaller than a preset saturation threshold. If so, then enter step 212, if not, then enter step 214;

Step 212 , adjust the color saturation of the display picture at the next moment based on the current ambient light brightness.

Step 214, maintaining the original color saturation for the display picture at the next moment.

Wherein, the preset saturation threshold may be obtained based on multiple experiments. That is, when the current ambient light brightness is greater than the preset ambient light brightness and the saturation is lower than a certain saturation threshold, the display effect of the display screen on the electronic device is lower than the preset requirement, which cannot meet the user's viewing needs. Then use the saturation threshold as the preset saturation threshold.

Finally, it is judged whether the color saturation of the currently displayed image is smaller than a preset saturation threshold. If yes, it means that under the current ambient light brightness greater than the preset ambient light brightness, the display effect of the display screen on the electronic device is lower than the preset requirement, which cannot meet the viewing needs of the user. Therefore, it is necessary to adjust the color saturation of the display picture at the next moment based on the current ambient light brightness. Specifically, it may be to enhance the color saturation of the display screen at the next moment.

In the embodiment of the present application, a display screen adjustment method is proposed. First, the display parameters of the current display screen on the display screen are obtained. If the display parameters meet the preset brightness adjustment conditions, the display parameters of the current display screen are determined. Target backlight brightness for this display. The current backlight brightness of the display screen is adjusted based on the target backlight brightness. Secondly, in this embodiment, for the situation that the current ambient light brightness is greater than the preset ambient light brightness, the color saturation of the display picture at the next moment is adjusted based on the current ambient light brightness. Finally, the display screen is adjusted from two different dimensions of backlight brightness and color saturation, so as to improve the display effect of the display screen.

Continuing from the previous embodiment, the acquisition of the color saturation of the currently displayed picture includes:

Divide the current display screen into different display areas;

The color saturation of each display area is identified to obtain the color saturation of each display area.

Specifically, if the current ambient light brightness is greater than the preset ambient light brightness, the color saturation of the currently displayed image is acquired. When acquiring the color saturation of the current display screen, the current display screen may be divided into different display areas first. Secondly, the color saturation of each display area is identified to obtain the color saturation of each display area.

In the embodiment of the present application, because the color saturation of different display areas in the current display screen may vary greatly, if only the average color saturation of the entire display screen is calculated, the color saturation of different display areas cannot be well reflected. In the case of low temperature, it is impossible to adjust the color saturation of different display areas in a targeted manner. Therefore, when acquiring the color saturation of the current display picture, the current display picture may be divided into different display areas first. Secondly, the color saturation of each display area is identified to obtain the color saturation of each display area. In this way, it is possible to adjust the color saturation of different display areas in a targeted manner, so as to improve the display effect of the display screen in a more refined manner.

Continuing from the previous embodiment, the color saturation adjustment of the display screen at the next moment is performed based on the current ambient light brightness, including:

From each of the display areas, determine a display area to be adjusted whose color saturation is less than the preset saturation threshold;

Based on the current ambient light brightness, the color saturation is adjusted for the target display area corresponding to the display area to be adjusted in the display screen at the next moment.

Specifically, when acquiring the color saturation of the current display picture, the current display picture may be divided into different display areas first. Secondly, the color saturation of each display area is identified to obtain the color saturation of each display area.

Then, from each of the display areas, determine the display areas to be adjusted whose color saturation is less than the preset saturation threshold. Then, from the display screen at the next moment, the target display area corresponding to the display area to be adjusted is determined. Based on the current ambient light brightness, the color saturation of the target display area in the display screen at the next moment is adjusted. Wherein, the target display area corresponding to the display area to be adjusted refers to the area in the display screen at the next moment in the same position as the area to be adjusted in the current display screen. It may also be an area with the same display content as the area to be adjusted in the current display image in the display image at the next moment, which is not limited in the present application.

In the embodiment of the present application, from each of the display areas, the display area to be adjusted whose color saturation is smaller than the preset saturation threshold is determined. Then, from the display screen at the next moment, the target display area corresponding to the display area to be adjusted is determined. Based on the current ambient light brightness, the color saturation of the target display area in the display screen at the next moment is adjusted. Based on the different display areas in the current display screen, targeted color saturation adjustments are performed on different display areas in the display screen at the next moment, so as to improve the display effect of the display screen in a more refined manner.

In one embodiment, as shown in FIG. 5 , adjusting the color saturation of the next display screen based on the current ambient light brightness includes:

Step 520, acquiring a preset relationship between ambient light brightness and color saturation.

The preset relationship between ambient light brightness and color saturation can be obtained through testing. That is, under different ambient light levels, the color saturation that meets the user's display requirements can be obtained through testing. This application does not do too much explanation.

Step 540, determine the target color saturation corresponding to the current ambient light brightness from the preset relationship.

After obtaining the preset relationship between the ambient light brightness and the color saturation, based on the current ambient light brightness, the target color saturation corresponding to the current ambient light brightness can be determined from the preset relationship.

Step 560, adjust the color saturation of the display picture at the next moment based on the target color saturation.

Specifically, the target display areas in the display screen at the next moment may be adjusted respectively based on the target color saturation. Wherein, the target display area in the display screen at the next moment corresponds to the display area to be adjusted in the current display screen. That is, the target display area in the display screen at the next moment is adjusted to the target color saturation.

In the embodiment of the present application, a preset relationship between ambient light brightness and color saturation is obtained, and a target color saturation corresponding to the current ambient light brightness is determined from the preset relationship. Based on the target color saturation, the color saturation of the display picture at the next moment is adjusted.

In one embodiment, as shown in FIG. 6, before acquiring the display parameters of the currently displayed picture on the display screen, including:

Step 620, collect the current ambient light brightness through the light sensor.

Electronic devices are generally equipped with a light sensor (Light-Sensor), also called a brightness sensor. Generally located above the display screen of the electronic device, the light sensor can automatically adjust the brightness of the display screen of the electronic device according to the brightness of the light in which the electronic device is located, so as to bring better visual effects to the user. For example, in a dark environment, the corresponding backlight of the display screen of the electronic device will be automatically dimmed, so as to avoid the glare caused by the backlight that remains too bright in a dark environment.

Step 640: Determine the initial backlight brightness of the display screen based on the current ambient light brightness according to the correspondence between the ambient light brightness and the backlight brightness.

Here, the corresponding relationship between the ambient light brightness and the backlight brightness can be reflected through the backlight adjustment curve of the ambient light brightness and the backlight brightness. The electronic device automatically determines the initial backlight brightness of the display screen based on the current ambient light brightness according to the backlight adjustment curve of the ambient light brightness and the backlight brightness. Generally, the backlight adjustment curve is obtained through debugging based on the fact that the current display image is a white image (in other words, the gray value of the current display image is 255). That is, no matter what display screen is displayed on the electronic device, under the same ambient light brightness, the display screen adjusted by the electronic device based on the backlight adjustment curve is at the same backlight brightness.

Step 660, adjust the backlight brightness of the display screen based on the initial backlight brightness.

After the electronic device automatically determines the initial backlight brightness of the display screen based on the current ambient light brightness based on the backlight adjustment curve of the ambient light brightness and the backlight brightness, the backlight brightness of the display screen is automatically adjusted based on the initial backlight brightness. Adjust the backlight brightness of the display to the original backlight brightness.

In the embodiment of the present application, the current ambient light brightness is first collected by the light sensor, and the initial backlight brightness of the display screen is determined based on the current ambient light brightness according to the corresponding relationship between the ambient light brightness and the backlight brightness. The backlight brightness of the display screen is automatically adjusted based on the initial backlight brightness. Then, the display parameters of the currently displayed picture on the display screen are obtained, and if the display parameters meet the preset brightness adjustment conditions, the target backlight brightness of the display screen is determined according to the display parameters of the currently displayed picture. The current backlight brightness of the display screen is adjusted based on the target backlight brightness. First perform automatic backlight brightness adjustment based on the corresponding relationship between ambient light brightness and backlight brightness, then determine the target backlight brightness of the display screen according to the display parameters of the current display screen, and determine the current backlight brightness of the display screen based on the target backlight brightness Brightness is adjusted. From the two dimensions of the current ambient light brightness and the display parameters of the current display screen, the current backlight brightness of the display screen can be adjusted to adjust to a suitable backlight brightness for different display screens, which can improve the clarity of different display screens and improve display effect.

In one embodiment, as shown in FIG. 7, a method for adjusting a display screen includes:

Step 720, if the current ambient light brightness is greater than the preset ambient light brightness, then obtain the color saturation of the current display image;

Step 740, judging whether the color saturation of the currently displayed image is less than a preset saturation threshold; if yes, proceed to step 760, if not, proceed to step 780;

Step 760 , adjust the color saturation of the display picture at the next moment based on the current ambient light brightness.

Step 780, maintaining the original color saturation for the display picture at the next moment.

This embodiment mainly aims at the situation that the current ambient light brightness is greater than the preset ambient light brightness, and adjusts the color saturation of the display picture at the next moment based on the current ambient light brightness. Specifically, for the situation that the current ambient light brightness is greater than the preset ambient light brightness, the color saturation of the display picture at the next moment is adjusted based on the current ambient light brightness. First, it is judged whether the current ambient light brightness is greater than the preset ambient light brightness. Here, the preset ambient light brightness refers to the ambient light brightness (High-brightness-Model, HBM) in the high-brightness mode, which generally includes the ambient light brightness higher than 10000 lux. Generally, such ambient brightness will appear when the user is outdoors under the sunlight. At this time, due to the influence of sunlight and reflection, the color saturation of the display screen on the electronic device will be relatively low, which will affect the viewing effect of the user.

Secondly, if the current ambient light brightness is greater than the preset ambient light brightness, the color saturation of the currently displayed image is acquired. Wherein, the color saturation is a display parameter in the HSV (hue, saturation, value) color space, also referred to as saturation. When obtaining the color saturation of the currently displayed image, an average color saturation of the entire currently displayed image may be obtained.

Finally, it is judged whether the color saturation of the currently displayed image is smaller than a preset saturation threshold. If yes, it means that under the current ambient light brightness greater than the preset ambient light brightness, the display effect of the display screen on the electronic device is lower than the preset requirement, which cannot meet the viewing needs of the user. Therefore, it is necessary to adjust the color saturation of the display picture at the next moment based on the current ambient light brightness. Specifically, it may be to enhance the color saturation of the display screen at the next moment. Wherein, the preset saturation threshold may be obtained based on multiple experiments. That is, when the current ambient light brightness is greater than the preset ambient light brightness and the saturation is lower than a certain saturation threshold, the display effect of the display screen on the electronic device is lower than the preset requirement, which cannot meet the user's viewing needs. Then use the saturation threshold as the preset saturation threshold.

In the embodiment of the present application, mainly for the situation that the current ambient light brightness is greater than the preset ambient light brightness, the color saturation of the display screen at the next moment is adjusted based on the current ambient light brightness. Finally, the display picture is adjusted from the dimension of color saturation to improve the display effect of the display picture.

Following the previous embodiment, the acquisition of the color saturation of the currently displayed picture includes:

Divide the current display screen into different display areas;

The color saturation of each display area is identified to obtain the color saturation of each display area.

Specifically, if the current ambient light brightness is greater than the preset ambient light brightness, the color saturation of the currently displayed image is acquired. When acquiring the color saturation of the current display screen, the current display screen may be divided into different display areas first. Secondly, the color saturation of each display area is identified to obtain the color saturation of each display area.

In the embodiment of the present application, because the color saturation of different display areas in the current display screen may vary greatly, if only the average color saturation of the entire display screen is calculated, the color saturation of different display areas cannot be well reflected. In the case of low temperature, it is impossible to adjust the color saturation of different display areas in a targeted manner. Therefore, when acquiring the color saturation of the current display picture, the current display picture may be divided into different display areas first. Secondly, the color saturation of each display area is identified to obtain the color saturation of each display area. In this way, it is possible to adjust the color saturation of different display areas in a targeted manner, so as to improve the display effect of the display screen in a more refined manner.

In the previous embodiment, the color saturation adjustment of the display screen at the next moment based on the current ambient light brightness includes:

From each of the display areas, determine a display area to be adjusted whose color saturation is less than the preset saturation threshold;

Based on the current ambient light brightness, the color saturation is adjusted for the target display area corresponding to the display area to be adjusted in the display screen at the next moment.

Specifically, when acquiring the color saturation of the current display picture, the current display picture may be divided into different display areas first. Secondly, the color saturation of each display area is identified to obtain the color saturation of each display area.

Then, from each of the display areas, determine the display areas to be adjusted whose color saturation is less than the preset saturation threshold. Then, from the display screen at the next moment, the target display area corresponding to the display area to be adjusted is determined. Based on the current ambient light brightness, the color saturation of the target display area in the display screen at the next moment is adjusted. Wherein, the target display area corresponding to the display area to be adjusted refers to the area in the display screen at the next moment in the same position as the area to be adjusted in the current display screen. It may also be an area with the same display content as the area to be adjusted in the current display image in the display image at the next moment, which is not limited in the present application.

In the embodiment of the present application, from each of the display areas, the display area to be adjusted whose color saturation is smaller than the preset saturation threshold is determined. Then, from the display screen at the next moment, the target display area corresponding to the display area to be adjusted is determined. Based on the current ambient light brightness, the color saturation of the target display area in the display screen at the next moment is adjusted. Based on the different display areas in the current display screen, targeted color saturation adjustments are performed on different display areas in the display screen at the next moment, so as to improve the display effect of the display screen in a more refined manner.

In a specific embodiment, as shown in FIG. 8 , a display screen adjustment method is provided, including:

Step 802, taking a screenshot of the current display screen on the display screen to obtain a target image corresponding to the current display screen;

Step 804, performing grayscale value recognition on the target image to obtain the grayscale value of the currently displayed image;
