detailed description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

Fig. 1 is a flow chart showing a display mode switching method according to an exemplary embodiment. As shown in Fig. 1 , this embodiment is described by taking the display mode switching method applied to an operating system on a terminal as an example. The display mode switching method may include the following steps.

In step 101, a first display mode of an operating system is obtained.

In step 102, when the first display mode of the operating system is the night mode, the second display mode of the application being displayed on the screen is switched to the night mode in a predetermined manner.

Wherein, the predetermined method includes: converting the first type of elements in the user interface of the application program to a predetermined color tone, and/or adding a layer of predetermined transparency on the second type of elements in the user interface of the application program, and the predetermined color tone is The hue corresponding to night mode.

To sum up, in the display mode switching method provided in the embodiments of the present disclosure, when the first display mode of the operating system is the night mode, by converting the first type of elements in the user interface to a predetermined tone and/or in the user interface Add a layer of predetermined transparency on the second type of elements of the , and switch the second display mode of the application being displayed on the screen to night mode; due to changing the white color on the user interface of the application by converting the color tone or adding a layer or light-colored areas, which reduces the contrast between the light emitted by the screen and the dark light environment, and solves the problem that the manual adjustment range of the screen brightness is limited. There is still a high contrast between the light environment, which will damage the user's vision; it has achieved the effect of reducing the contrast between the screen light and the dark environment, reducing the stimulation of light to the eyes, and protecting the user's vision.

Fig. 2 is a flow chart showing a display mode switching method according to another exemplary embodiment. As shown in Fig. 2 , this embodiment is described by taking the display mode switching method applied to an operating system on a terminal as an example. The display mode switching method may include the following steps.

In step 201, when it is detected that the light intensity is less than the first threshold, the first display mode of the operating system is switched to the night mode.

In a possible implementation, when the operating system detects that the light intensity of the surrounding environment is lower than the first threshold, it automatically switches the first display mode of the operating system to the night mode, so as to reduce the difference between the screen light and the environment with weak light intensity. contrast between.

The first display mode is a system-level display mode.

The night mode is a display mode suitable for light intensity less than a predetermined threshold.

In another possible implementation manner, the operating system is provided with a switch for the first display mode, and the user can manually control the switch to determine the first display mode of the operating system. The first display mode is valid for the operating system and various application programs running on the operating system.

For example: a global night mode switch provided by the operating system to the user, add a code whose key is "**ui_night_mode_enabled" and the value is 0 or 1 in the program corresponding to the setting resource, **ui is the name of the operating system, and the value is A value of 1 means that the night mode of the operating system is turned on, a value of 0 means that the night mode of the operating system is turned off, and the default is off. When the switch is switched, the value will also change, and the operating system can determine the first display mode corresponding to the operating system according to the value of the night mode.

Optionally, when the operating system detects that the light intensity is less than the first threshold, a prompt message is displayed on the screen, and the prompt message is used to prompt the user to turn on the night mode of the operating system.

When the user sees the prompt message on the screen, the user can switch the first display mode of the operating system to the night mode by controlling the switching switch of the first display mode.

In step 202, a first display mode of the operating system is obtained.

The operating system can determine the current first display mode of the operating system by reading the value of the night mode.

In step 203, when the first display mode of the operating system is the night mode, it is detected whether the application being displayed on the screen supports the night mode in the application.

Optionally, the operating system detects whether the application supports the night mode in the application through the following methods:

In the first step, the predetermined identification in the header file of the application is read.

The value of the predetermined flag is used to indicate whether the application supports the night mode in the application.

In the second step, when the value of the predetermined identifier is the first value, it is determined that the application program does not support the night mode in the application program.

For example: the name of the predetermined identifier is: name="support_**ui_night_mode", and the value is: value="false", indicating that the application program does not support the night mode in the application, and the first value is false.

Optionally, if the value of the predetermined identifier is the second value, it indicates that the application supports the night mode in the application, then the application stores mode parameters about the night mode, and the application, according to the first display mode of the operating system, You only need to switch to the corresponding second display mode according to the mode parameters of the night mode provided by yourself. Correspondence refers to that the first display mode and the second display mode are both night mode or normal mode.

The second display mode is an application-level display mode. The night mode is a display mode suitable for light intensity less than a first threshold, and the normal mode is a display mode suitable for light intensity greater than a second threshold, and the first threshold is the same as or different from the second threshold.

In a possible implementation, if there is no predetermined identifier in the header file of the application, the operating system directly determines that the application does not support the night mode in the application.

In step 204, when the application does not support the night mode in the application, the second display mode of the application being displayed on the screen is switched to the night mode in a predetermined manner.

The second display mode is an application-level display mode.

Optionally, the predetermined manner includes: converting the first type of elements in the user interface of the application program to a predetermined color tone, and/or adding a layer of predetermined transparency on the second type of elements in the user interface of the application program. Wherein, the predetermined color tone is the color tone corresponding to the night mode.

The collection of the elements of the first type and the elements of the second type constitutes the user interface of the application program, and the intersection between the elements of the first type and the elements of the second type may or may not exist.

When there are only elements of the first type and no elements of the second type on the user interface of the application, the elements of the first type form the user interface of the application; when there are only elements of the second type and no elements of the first type on the user interface of the application , the second class of elements that make up the application's user interface.

Elements on the user interface include pictures, text, buttons, controls, backgrounds, etc.

The elements of the first type may overlap with the elements of the second type, or the elements of the first type and the elements of the second type are the same, or the elements of the first type are all on the user interface, or the elements of the second type are all on the user interface.

With reference to FIG. 3 , if the predetermined manner includes: converting the first type of elements in the user interface of the application program to a predetermined color tone, then step 204 may be replaced by steps 204a to 204b.

In step 204a, when the application program does not support the night mode in the application program, the picture in the user interface of the application program is converted to a predetermined tone.

The color tone refers to at least one color included in the user interface of the application program, for example: the background of the user interface is black, the button control in the user interface is dark gray, and the text in the user interface is light gray. For different elements in the user interface, the application switches to the corresponding color according to the mode parameter of the night mode.

With reference to FIG. 4 , the user interface of the reading application is displayed on the screen 10. The user interface includes a title area 11 and a text area 12. When the second display mode of the reading application is the normal mode, the background of the title area 11 The color is off-white, the background color of the text area 12 is white, and the text color is black. When the second display mode of the reading application is switched from normal mode to night mode, the background color of the title area 21 is converted to dark gray, and the text area The background color of 22 is light gray, and the text color is off-white.

Optionally, converting the picture in the user interface of the application program to a predetermined tone can be achieved through the following steps:

In the first step, the image type of the image in the user interface of the application is detected.

The picture type includes: a first picture type and a second picture type, the height of the first picture type is equal to the pixel height of the screen or the width of the first picture type is equal to the pixel width of the screen, the height of the second picture type is smaller than the pixel height of the screen and The width of the second image type is smaller than the pixel width of the screen.

In the second step, when the picture in the user interface of the application program belongs to the first picture type, convert the picture into a predetermined tone according to the first color matrix.

In the third step, when the picture in the user interface of the application program belongs to the second picture type, convert the picture into a predetermined tone according to the second color matrix.

Wherein, the second step and the third step are parallel steps, and the first color matrix in the second step is different from the second color matrix in the third step.

Since the operating system cannot distinguish the function of each picture in the user interface during actual implementation, it is identified according to the size of the picture. For example: if the height multiplied by the width of the picture is equal to the screen size, then the picture is determined to be the background.

For pictures of different sizes in the user interface, the converted colors are different, and the converted color of each picture belongs to a predetermined tone. Among them, the color matrix is a 5*4 matrix. For example, the color matrix M is a one-dimensional array [a,b,c,d,e,f,g,h,I,j,k,l,m,n , o, p, q, r, s, t] to store, expressed as:

In the picture, the RGBA (red, green, blue, transparency) value determines the color effect of the picture. By multiplying the color matrix with the RGBA value of the picture, the picture can be changed according to the color matrix.

In the color matrix, the parameter abcde in the first line determines the red component of the picture, the parameter fghij in the second line determines the green component of the picture, the parameter klmno in the third line determines the blue component of the picture, and the parameter pqrst in the fourth line determines the transparency of the picture. , e in the fifth column parameter determines the offset of red, j determines the offset of green, o determines the offset of blue, and t determines the offset of transparency.

If the color of the picture is not changed, the color matrix is:

Changing the color can be realized directly by modifying the color offset of the fifth column, for example: if e=100, the red component of the picture can be increased by 100.

In addition, changing the color can also directly multiply a certain color value by a certain coefficient to achieve the purpose of changing the color component. For example, if the color matrix is:

Then the green component is enlarged by 2 times, and the effect of the picture is green.

In step 204b, when the application program does not support the night mode in the application program, the text in the user interface of the application program is converted into a predetermined color, and the predetermined color is a color belonging to a predetermined tone.

For the text in the user interface, the same method is used to determine the color matrix of the color to be converted to the text, and multiply the color matrix by the text color to obtain the converted text color.

Optionally, in actual implementation, the parameters of the color matrix can also be changed by controlling the operating system through the cloud, so as to achieve the effect of converting different elements into different colors.

Wherein, both step 204a and step 204b may be executed, or only one of them may be executed.

With reference to FIG. 3 , if the predetermined method includes: adding a layer of predetermined transparency on the second type of element in the user interface of the application program, then step 204 may be replaced by steps 204c to 204e.

In step 204c, when the application does not support the night mode in the application, the picture type of the picture in the user interface of the application is detected.

The picture type includes: a first picture type and a second picture type, the height of the first picture type is equal to the pixel height of the screen or the width of the first picture type is equal to the pixel width of the screen, the height of the second picture type is smaller than the pixel height of the screen and The width of the second image type is smaller than the pixel width of the screen.

In step 204d, when the picture in the user interface of the application belongs to the first picture type, a first transparency layer is added to the picture.

In step 204e, when the picture in the user interface of the application belongs to the second picture type, a second transparency layer is added to the picture.

Wherein, step 204d and step 204e are parallel steps.

The first transparency is different from the second transparency, and the value range of the first transparency and the second transparency is 0 to 1, 0 means completely transparent, and 1 means opaque.

For the pictures in the user interface, layers with different transparency are added according to different sizes of different pictures, that is, layers with different sizes are processed in different degrees.

Optionally, when implementing the night mode, the added layer is usually a black layer.

In practical applications, steps 204a to 204b and steps 204c to 204e are parallel solutions. When implementing the night mode, only steps 204a to 204b may be performed, or only steps 204c to 204e may be performed.

Optionally, the solutions in steps 204a to 204b and steps 204c to 204e may be implemented in combination. Night mode can be implemented in different ways for different elements of an application's user interface. For example: in an instant messaging application, the user interface background image is converted to a predetermined color tone, and a layer is added to the image in the message sent between users. Since the pictures in the messages sent between users are what users need to read, if the color is changed, the pictures will lose readability. Therefore, the contrast between the pictures and the dark light environment is reduced by adding layers to maintain the clarity of the pictures. readability.

Optionally, the predetermined manner further includes: adjusting the brightness of the backlight of the screen to a brightness value corresponding to the night mode.

Optionally, the brightness value corresponding to the night mode is smaller than the minimum value of the manually adjustable range of the backlight brightness of the screen.

Due to the limited manual adjustable range of the backlight brightness of the screen, even if the brightness value is adjusted to the minimum value of the manual adjustable range, the contrast between the light of the screen and the dark ambient light is still large, so the operating system can adjust the brightness value to Adjust below the minimum value of the manually adjustable range to reduce the brightness of the screen's backlight. For example: adjust the brightness value to 10% below the minimum value of the manual adjustable range.

Optionally, when the first display mode of the operating system is switched to the normal mode, the operating system also switches the second display mode of the application being displayed on the screen to the normal mode.

The process of switching the second display mode to the normal mode corresponds to the process of switching the second display mode to the night mode, which are reciprocal processes. For example: when the second display mode is switched to night mode, through color conversion, when the second display mode is switched to normal mode, the color will be converted to the original color; when the second display mode is switched to night mode, By adding layers, when the second display mode is switched to normal mode, the layer will be removed; when the second display mode is switched to night mode, by reducing the brightness value, the second display mode will be switched to In normal mode, restore the brightness value.

To sum up, in the display mode switching method provided in the embodiments of the present disclosure, when the first display mode of the operating system is the night mode, by converting the first type of elements in the user interface to a predetermined tone and/or in the user interface Add a layer of predetermined transparency on the second type of elements of the , and switch the second display mode of the application being displayed on the screen to night mode; due to changing the white color on the user interface of the application by converting the color tone or adding a layer or light-colored areas, which reduces the contrast between the light emitted by the screen and the dark light environment, and solves the problem that the manual adjustment range of the screen brightness is limited. There is still a high contrast between the light environment, which will damage the user's vision; it has achieved the effect of reducing the contrast between the screen light and the dark environment, reducing the stimulation of light to the eyes, and protecting the user's vision.

For step 201, the operating system switches the first display mode to the night mode when it detects that the light intensity is less than the first threshold, so that the operating system switches only when the terminal is in a dark light environment, reducing the light and dark light of the screen. The contrast between environments reduces the irritation to the user's eyes and protects the user's eyesight.

For steps 203 to 204, when it is detected that the application does not support the night mode in the application, the application program being displayed on the screen is processed in a predetermined manner, so that the application program that does not support the night mode in the application can also be displayed The effect of night mode can be realized, thereby reducing the contrast between the screen light and the dark light environment, reducing the stimulation to the user's eyes, and protecting the user's eyesight.
