Background technique

At present, many electronic devices (such as mobile phones, tablet computers, etc.) are provided with display screens, and for the display screens, users often need to adjust the brightness of the screen. In the prior art, the adjustment of screen brightness generally includes two methods. One method is automatic adjustment, that is, the screen brightness automatically changes with the change of the brightness of the external environment; the other method is manual adjustment, that is, the user manually adjusts according to their own needs. Adjust screen brightness.

For the automatic adjustment method, the user does not need to perform an adjustment operation of the screen brightness, which is convenient to use. However, for some users, they are more accustomed to adjusting the screen brightness according to their own needs, so the automatic adjustment function will be turned off and the manual adjustment method will be adopted.

Generally, there is a positive correlation between screen brightness and ambient brightness, that is, the higher the ambient brightness, the higher the screen brightness; the lower the ambient brightness, the lower the screen brightness. After the automatic screen brightness adjustment function is turned off, in some special scenarios, the screen brightness may not match the ambient brightness, which affects the user's viewing of the displayed content on the screen. For example, suddenly entering an environment with high light intensity (such as an environment with direct sunlight), it may be difficult to see the display content on the screen due to the low screen brightness; or suddenly entering an environment with low light intensity (such as no night) light environment), it may be dazzling due to the high brightness of the screen. In the above two scenarios, due to the large contrast between the ambient brightness and the screen brightness, the screen brightness lacks comfort, which affects the user's use of the screen, making it inconvenient for the user to adjust the screen brightness in this scenario. question.

In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The following describes the screen brightness adjustment method provided by the embodiments of the present application in detail through specific embodiments and application scenarios with reference to the accompanying drawings.

FIG. 1 is a schematic flowchart of a method for adjusting screen brightness provided by an embodiment of the present application. The method for adjusting screen brightness is applied to an electronic device provided with a screen.

As shown in Figure 1, the screen brightness adjustment method includes:

Step 101 : in the case that the automatic brightness adjustment function of the screen is turned off, obtain a first ambient brightness value of the current environment.

In the embodiment of the present application, when the automatic brightness adjustment function of the screen is turned off, the ambient brightness value (ie the first ambient brightness value) of the environment where the electronic device is located (ie the current environment) can be acquired in real time or regularly.

For many current electronic devices (such as mobile phones, tablet computers, etc.), a photosensitive sensor is a necessary device. Therefore, in the embodiments of the present application, the brightness value of the current environment can be obtained through the photosensitive sensor installed in the electronic device.

Step 102: In the case that the current first screen brightness value of the screen does not match the first environment brightness value, display at least one brightness adjustment button.

In this embodiment of the present application, after obtaining the brightness value of the current environment, it can be determined whether the current brightness of the screen matches the brightness of the current environment. In the case where it is determined that there is no match between the two, at least one brightness adjustment key is displayed.

Among them, each brightness adjustment button corresponds to a screen brightness value, that is, when different brightness adjustment buttons are touched, the screen brightness will be adjusted to different brightness values, and after touching a brightness adjustment button, the screen brightness is directly adjusted to the same brightness adjustment button. Corresponds to the screen brightness value. In addition, the screen brightness value corresponding to each brightness adjustment button matches the brightness value of the current environment.

Step 103: Receive a first input from the user on the target brightness adjustment key.

The target brightness adjustment key described here is one of the at least one brightness adjustment key described in step 102 .

The first input described here may include, but is not limited to, a single-click touch operation, a double-click touch operation, a long-press touch operation, or a re-press touch operation, and the like.

Step 104: In response to the first input, adjust the brightness of the screen to the target screen brightness value.

The target screen brightness value is the screen brightness value corresponding to the target brightness adjustment button.

After receiving the first input, the electronic device responds to the first input and adjusts the brightness of the screen to the target screen brightness value, where the target screen brightness value is the screen brightness value corresponding to the target brightness adjustment button.

In the embodiment of the present application, after the automatic brightness adjustment function of the screen is turned off, if the current brightness of the screen does not match the ambient brightness (such as when the contrast is large), the brightness adjustment button may be automatically displayed for the user to adjust Screen brightness, saving the user the operation work of finding the brightness adjustment button. In addition, the brightness adjustment button in the embodiment of the present application is a one-key brightness adjustment, that is, after touching a brightness adjustment button, the screen brightness can be directly adjusted to the screen brightness value corresponding to the brightness adjustment button. Compared with the traditional brightness adjustment button Drag the adjustment method to adjust the brightness more quickly. Further, in the embodiment of the present application, the screen brightness value corresponding to each brightness adjustment button matches the brightness of the current environment, and the user does not need to try and explore, which makes the brightness adjustment operation more convenient.

In a word, the screen brightness adjustment method provided by the embodiments of the present application can enable the user to conveniently and quickly adjust the screen brightness to an appropriate brightness when the screen brightness does not match the ambient brightness, thereby reducing the length of time that brings inconvenience to the user.

Optionally, after the brightness adjustment button is displayed, if the user does not want to adjust the screen brightness, the display of the brightness adjustment button can be canceled through a preset operation, such as voice input control, touch operation on the touch screen (such as clicking the brightness adjustment button). The display area outside the button), the touch operation of the preset physical buttons (such as the power button, the home button, etc.) or the air gesture operation, etc.

Optionally, the number of brightness adjustment keys is one. When the brightness of the screen does not match the brightness of the environment, the user's expectation is to adjust the brightness of the screen as soon as possible to better view the contents of the screen. Therefore, a brightness adjustment button can quickly complete the brightness adjustment while meeting the brightness requirements, making The adjustment process is simpler.

Optionally, the number of brightness adjustment keys is at least two. Different users have different perception capabilities of light, therefore, providing multiple brightness adjustment buttons enables users to select a screen brightness that is more suitable for them, thereby improving comfort.

Optionally, the brightness adjustment buttons can be arranged in the direction from left to right or from top to bottom, according to the corresponding screen brightness value in ascending order, so that the user can distinguish the screen brightness corresponding to each brightness adjustment button. value relationship. Wherein, the left and right described here are the directions of the user as a reference. For example, the left described here is: the left side of the user when the screen is set face to face with the user, and the right described here is: the screen faces the user. The right side of the user when set relative. The upper and lower mentioned here are the directions of the electronic device as a reference object, wherein the top of the electronic device is taken as the top and the bottom of the electronic device is taken as the bottom.

Optionally, as mentioned above: in the case that the current first screen brightness value of the screen does not match the first ambient brightness value, at least one brightness adjustment button is displayed. Whether the ambient brightness values match, the embodiment of the present application provides an implementation method, as follows:

Before step 102, the screen brightness adjustment method may further include:

Determine the target screen brightness value range corresponding to the first ambient brightness value according to the preset correspondence between the ambient brightness value and the screen brightness value; when the first screen brightness value is not within the target screen brightness value range Next, determine that the brightness value of the first screen does not match the brightness value of the first environment; when the brightness value of the first screen is within the range of the brightness value of the target screen, determine that the brightness value of the first screen matches the brightness value of the first environment .

In this embodiment of the present application, a preset correspondence relationship between the ambient brightness value and the screen brightness value may be preset. The screen brightness value corresponding to each ambient brightness value is: a screen brightness suitable for the user to view the screen content under the ambient brightness of the ambient brightness value.

After the first ambient brightness value of the current environment is acquired, the screen brightness value corresponding to the first ambient brightness value (hereinafter referred to as the second screen brightness value) can be determined according to the preset correspondence between the ambient brightness value and the screen brightness value. value), and then determine a target screen brightness value range according to the second screen brightness value and the preset brightness redundancy amount (a non-zero value). If the first screen brightness value is within the range of the target screen brightness value, it is considered that the first screen brightness value matches the first ambient brightness value; if the first screen brightness value is not within the target screen brightness value range, then It is considered that the first screen brightness value does not match the first ambient brightness value.

Optionally, when it is determined that the first screen brightness value does not match the first environment brightness value, the screen brightness adjustment method may further include: determining the number of brightness adjustment buttons according to the target screen brightness value range.

In this embodiment of the present application, the number of brightness adjustment buttons may be determined according to the range of the brightness value of the target screen. For example, the target screen brightness value range is [100, 200], and then preset every 30 brightness values to generate a brightness adjustment button. If the screen brightness value corresponding to the first brightness adjustment button is 100, then according to the range of the target screen brightness value, 4 brightness adjustment buttons can be obtained, and the screen brightness value corresponding to each brightness adjustment button from small to large is: 100 , 130, 160, 190. The preset difference between the screen brightness values corresponding to two adjacent brightness adjustment buttons may be set according to actual needs. The screen brightness value corresponding to the first brightness adjustment button may take the minimum value in the target screen brightness value range, or other value-taking rules may be set to take the value, which is not limited in this embodiment of the present invention.

Optionally, in the case that the brightness of the screen does not match the brightness of the environment, if the user does not need to view the content displayed on the screen, there is no need to adjust the brightness of the screen. Therefore, in this embodiment of the present application, before displaying at least one brightness adjustment button , and can also detect whether the user has the need to view the content displayed on the screen. For how to detect whether the user has the need to view the content displayed on the screen, the embodiment of the present application provides the following implementation methods:

Step 103: Display at least one brightness adjustment button, which may include:

When the first screen brightness value is less than the minimum value in the target screen brightness value range, and it is detected that the electronic device where the screen is located moves towards the user's face, displaying at least one brightness adjustment button;

Or, when the first screen brightness value is smaller than the minimum value in the target screen brightness value range, and it is detected that the user's eyes are fixed on the screen, at least one brightness adjustment button is displayed;

Or, when the first screen brightness value is greater than the maximum value in the target screen brightness value range, and it is detected that the electronic device moves away from the user's face, at least one brightness adjustment button is displayed;

Alternatively, when the first screen brightness value is greater than the maximum value in the target screen brightness value range, and it is detected that the user's eyes are fixed on the screen, at least one brightness adjustment button is displayed.

In this embodiment of the present application, it can be determined whether the user has a need to use the screen by changing the positional relationship between the electronic device and the user's face, and/or whether the user's eyes are looking at the screen. This is further explained below.

In the case where the first screen brightness value is less than the minimum value in the target screen brightness value range, it means that the screen brightness is relatively low relative to the ambient brightness, and the content displayed on the screen will be difficult to see due to the low screen brightness. If the user is using the screen, he will subconsciously bring the electronic device close to the face, so as to shorten the distance between the screen and the human eye, so as to view the displayed content. Therefore, in the case where the first screen brightness value is less than the minimum value in the target screen brightness value range, if it is detected that the electronic device moves towards the user's face, it can be considered that the user has the need to view the content displayed on the screen; If the electronic device does not move toward the user's face, it can be considered that the user does not need to view the content displayed on the screen.

When the first screen brightness value is greater than the maximum value in the target screen brightness value range, it means that the screen brightness is relatively high relative to the ambient brightness, and the screen will be dazzling due to the high brightness. At this time, if the user is using the screen, It will subconsciously move the electronic device away from the face to widen the distance between the screen and the human eye to avoid glare. Therefore, in the case where the first screen brightness value is greater than the maximum value in the target screen brightness value range, if it is detected that the electronic device moves away from the user's face, it can be considered that the user has the need to view the content displayed on the screen; If the electronic device does not move toward the user's face, it can be considered that the user does not need to view the content displayed on the screen.

Optionally, when detecting a change in the positional relationship between the electronic device and the user's face, the detection may be performed by a gravitational acceleration sensor and a camera set on the electronic device. For example, if the upward movement of the electronic device is detected by the gravitational acceleration sensor, and the user's face is determined to be at a top-down angle through the image obtained by the camera, it is considered that the electronic device is moving towards the user's face; or the downward movement of the electronic device is detected by the gravitational acceleration sensor, And if it is determined that the user's face is at an upward looking angle through the image obtained by the camera, it is considered that the electronic device is moving toward the user's face. For another example, if the downward movement of the electronic device is detected by the gravitational acceleration sensor, and the user's face is determined to be at a top-down angle through the image obtained by the camera, it is considered that the electronic device is moving away from the user's face; or the gravitational acceleration sensor detects that the electronic device moves upwards. , and it is determined from the image obtained by the camera that the user's face is at an upward looking angle, it is considered that the electronic device is moving away from the user's face.

It should be noted that the up and down mentioned here are defined with reference to the direction of gravity, and when the direction of gravity is the same as the direction of gravity, it is down, and when it is opposite to the direction of gravity, it is up.

Optionally, when detecting the change in the positional relationship between the electronic device and the user's face, the detection can also be performed by a distance sensor (eg, an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, etc.) provided on the electronic device. When it is detected that the distance between the electronic device and the user's face becomes gradually smaller, it is considered that the electronic device is moving towards the user's face; when the distance between the electronic device and the user's face is gradually increased, it is considered that the electronic device is far away from the user's face. face moves.

In the embodiment of the present application, in addition to determining whether the user has the need to use the screen through the change in the positional relationship between the electronic device and the user's face, it can also determine whether the user has the ability to view the screen by detecting whether the user's eyes are looking at the screen. Screen display content requirements. For example, if it is detected that the user's eyes are looking at the screen, it can be considered that the user has a need to view the content displayed on the screen; if it is detected that the user's eyes are not looking at the screen, it can be considered that the user has no need to view the content displayed on the screen.

Optionally, when detecting whether the user's eyes are looking at the screen, it can be determined by using an image obtained by a camera set on the electronic device. If the image obtained by the camera includes the image of the human eye, and it is determined according to the image of the human eye that the focus of the line of sight of the human eye is in the display area of the screen, it is determined that the user's eyes are looking at the screen; if the image obtained by the camera does not include the image of the human eye, or The human eye image is included, but when it is determined according to the human eye image that the focus of the line of sight of the human eye is not in the display area of the screen, it is determined that the user's eyes are not looking at the screen.

It can be understood that, the foregoing two implementation manners for determining whether the user has the requirement to use the screen may be used alone or in combination. When used in combination, at least one brightness adjustment button is displayed if and only when it is determined that the user has a need to use the screen through both implementations, which can improve the accuracy of user behavior judgment.

In the embodiment of the present application, in combination with the natural reaction of the human body to the brightness of the screen, the brightness adjustment button is amicably called up, so as to fit the actual needs of the user and make it easier for the user to accept.

Optionally, when the brightness of the screen is low relative to the brightness of the environment, when the brightness adjustment buttons are displayed, in order to facilitate the user to see the brightness adjustment buttons, the brightness adjustment buttons can be highlighted. Therefore, step 102: display at least one Brightness adjustment buttons, which can include:

In the case that the first screen brightness value is smaller than the minimum value in the target screen brightness value range, at least one brightness adjustment key is displayed. Wherein, the screen brightness value of the at least one brightness adjustment key is greater than the first screen brightness value, and is within the range of the target screen brightness value.

In the embodiment of the present application, when the brightness adjustment button is highlighted, the brightness value of the display area where the brightness adjustment button is displayed may only be controlled to be within the brightness value range of the target screen; or the brightness value of the entire display area of the screen may be controlled Within the range of the target screen brightness value, for the screen display area outside the display area of the brightness adjustment button, the display screen can be dimmed by specific technical means, so as to highlight the display of the brightness adjustment button. The specific technical means described here may include, but are not limited to: performing regional grayscale processing on the target display screen, displaying a preset transparency mask on the target display screen, or using a certain pixel algorithm to convert the pixels of the display screen It is a state with a low brightness value. Preferably, the brightness of the target display image can be adjusted to the first screen brightness value through specific technical means. The target display picture described here is a display picture in a display area other than the display area where the brightness adjustment button is located.

After the user touches the brightness adjustment button, the electronic device adjusts the screen brightness to a screen brightness value corresponding to the touched brightness adjustment button, and automatically cancels the display of the brightness adjustment button.

Among them, when adjusting the brightness of the entire display area or part of the screen in order to highlight the brightness adjustment button, if no processing operation on the terminal is detected within the preset time period, the original brightness (that is, the brightness value of the first screen) will be restored. ).

Optionally, when the brightness of the screen is relatively high relative to the ambient brightness, when the brightness adjustment buttons are displayed, in order to facilitate the user to view the brightness adjustment buttons, the brightness adjustment buttons can be highlighted. Therefore, step 102: display at least one brightness adjustment button. , which can include:

When the first screen brightness value is greater than the maximum value in the target screen brightness value range, preset processing is performed on the display image on the screen; after the preset processing is performed on the display image, at least one brightness adjustment button is displayed .

The preset processing described here is used to reduce the display brightness of the display screen, and may include: displaying a mask with preset transparency on the display screen, or performing regional grayscale processing on the display screen, or controlling the display screen The pixels of the picture are displayed with preset brightness values. Wherein, the preset brightness value is smaller than the first screen brightness value.

Among them, the screen brightness value of the brightness adjustment button is within the range of the target screen brightness value, and the screen brightness value is greater than the brightness value of the display screen after the preset processing, so that the brightness adjustment button can be highlighted while ensuring that the screen is not dazzling. , which is convenient for users to view.

After the user touches the brightness adjustment button, the electronic device adjusts the screen brightness to a screen brightness value corresponding to the touched brightness adjustment button, and automatically cancels the display of the brightness adjustment button.

In this embodiment, for a scenario where a user enters a dark environment from a bright environment, a series of methods can be used to process the display brightness of the entire screen, and then control the display of the brightness adjustment buttons, so that the user can quickly adjust the screen to an appropriate brightness , to ensure that the user will not irritate the eyes due to the excessively bright screen after entering the dark environment, and also avoids that the terminal automatically adjusts the screen to an excessively low brightness in the automatic brightness adjustment mode, causing the user to be unable to see the screen clearly.

Optionally, in this embodiment of the present application, in the case where the screen brightness does not match the ambient brightness value, the user can adjust the screen brightness not only through virtual brightness adjustment buttons, but also through physical buttons, for example, by The volume keys (including the volume up key and the volume down key) are used to adjust the screen brightness. For example, when the first screen brightness value is less than the minimum value in the target screen brightness value range, the screen brightness can be increased by pressing the volume plus button. At this time, the volume plus button corresponds to a screen brightness value, and pressing the volume plus button once After pressing the key, the screen brightness is adjusted to the screen brightness value. When the first screen brightness value is greater than the maximum value in the target screen brightness value range, the screen brightness can be reduced by pressing the volume down button. At this time, the volume down button corresponds to a screen brightness value. After pressing the volume plus button once , the screen brightness is adjusted to the screen brightness value.

In order to facilitate the user to identify the volume key to be pressed, a text or pattern prompt can be provided in the display area adjacent to the volume key to be touched. After the user presses the corresponding volume key according to the prompt, the screen brightness can be adjusted.

Finally, in order to better understand the screen brightness adjustment method provided by the embodiments of the present application, an example is used for further explanation below. In this example, the electronic device is a cell phone.

As shown in Figure 2, the adjustment process of this example may include:

Step 201 : initial state: turn off the automatic backlight function (ie, the screen brightness automatic adjustment function), and then proceed to step 202 .

After the automatic backlight function is turned off, the mobile phone will not automatically adjust the backlight brightness according to the ambient brightness, and must be manually adjusted by the user.

Step 202 , obtaining the current ambient brightness through the photosensitive sensor in the mobile phone, and then proceeding to step 203 .

Step 203: Determine whether the current backlight brightness of the mobile phone screen matches the ambient brightness. In the case of no match, if the backlight brightness is darker than the ambient brightness, go to step 204 , and if the backlight brightness is brighter than the ambient brightness, go to step 205 .

Step 204: Determine whether the mobile phone has an action of approaching the human eye through the gravitational acceleration sensor and the camera in the mobile phone. If the mobile phone has an action close to the human eye, go to step 206 , otherwise go to step 202 .

When the user enters a strong light environment, since the backlight brightness is relatively dark compared to the ambient brightness, the user needs to hold the mobile phone close to view. Therefore, the upward movement of the mobile phone is detected by the gravitational acceleration sensor, and the image obtained by the camera determines that the user's face is looking down. angle, it is determined that the mobile phone has an action close to the human eye; or when the downward movement of the mobile phone is detected through the gravitational acceleration sensor, and the user's face is determined to be at an upward looking angle through the image obtained by the camera, it is determined that the mobile phone has an action close to the human eye. .

Here and below, upper and lower are defined with reference to the direction of gravity. It is down when it is in the same direction as the direction of gravity, and it is up when it is opposite to the direction of gravity.

Among them, the upward movement speed and downward movement speed of the gravitational acceleration sensor can be set, and when the upward movement speed or downward movement speed of the gravitational acceleration sensor reaches the preset speed, it is determined whether the mobile phone has an action close to the human eye, so as to avoid false triggering.

Step 205: Determine whether the mobile phone has an action of moving away from the human eye through the gravitational acceleration sensor and the camera in the mobile phone. If the mobile phone has the action of moving away from the human eye, go to step 206 , otherwise go to step 202 .

When the user enters the dark light environment, because the backlight brightness is brighter than the ambient brightness, the user habitually holds the mobile phone far away to avoid glare. Therefore, the downward movement of the mobile phone is detected by the gravitational acceleration sensor, and the image obtained by the camera determines the user's identity. If the face is in a top-down angle, it is determined that the mobile phone has an action that is far away from the human eye; or when the mobile phone is detected to move upward through the gravitational acceleration sensor, and the user's face is determined to be in an upward viewing angle through the image obtained by the camera, it is determined that the mobile phone has a movement far away from the human eye. Actions.

Step 206: Determine whether the user is looking at the screen of the mobile phone through the camera. If it is determined that the user is looking at the screen of the mobile phone, the process proceeds to step 207 when the brightness of the screen backlight is too dark, and proceeds to step 208 when the brightness of the screen backlight is relatively bright.

After it is determined that the mobile phone has an action close to the human eye or an action far away from the human eye through the gravitational acceleration sensor and camera in the mobile phone, it can also determine whether the user is looking at the screen of the mobile phone through the camera, which can further determine whether the user is using the screen at this time. Thus, the accuracy of user behavior judgment is improved.

Step 207 : Display a brightness adjustment button, and increase the brightness of the display area where the brightness adjustment button is located, and then proceed to step 209 .

Wherein, the brightness adjustment button corresponds to a screen brightness value.

In the embodiment of the present application, when the brightness of the screen backlight is high, in order to facilitate the user to view the brightness adjustment button, the brightness adjustment button may be highlighted.

Step 208 : display a brightness adjustment button, and lower the brightness of the entire display area of the screen, and then proceed to step 209 .

Wherein, the brightness adjustment button corresponds to a screen brightness value.

In the embodiment of the present application, when the brightness of the screen backlight is relatively high, in order to facilitate the user to view the brightness adjustment buttons, the brightness of the entire display area of the screen may be controlled to decrease somewhat.
