Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

The technical solutions provided by the embodiments of the present disclosure relate to terminals, and the terminals may be mobile phones, tablet computers, and other devices having the function of adjusting screen brightness according to environmental brightness, which are not limited in the embodiments of the present disclosure. In the related art, the adjustment of screen brightness is based on the backlight driver chip set by the terminal. If the backlight driver chip provides more brightness levels, for example, the backlight driver chip provides 4096 brightness levels, the screen brightness can be evenly divided into from the darkest to the brightest. 4096 levels, the screen brightness changes little between two adjacent brightness levels, so the screen brightness can be uniformly changed. However, if the backlight driver chip provides less brightness levels, for example, the backlight driver chip provides 256 brightness levels, then the screen brightness can only be evenly divided into 256 levels from the darkest to the brightest, and the screen between two adjacent brightness levels The brightness changes greatly, so that when adjusting the screen brightness, the human eye can clearly feel the brightness jitter caused by the screen changes, which affects the user experience. In the technical solutions provided by the embodiments of the present disclosure, by inserting a transition brightness level between the current brightness level and the target brightness level, the brightness changes during the process of adjusting the brightness of the screen from the current brightness level to the target brightness level are relatively gentle, so that the The effect of uniform brightness transition improves the user experience.

Fig. 1a is a flow chart of a method for adjusting screen brightness according to an exemplary embodiment. The method is applied to a terminal. As shown in Fig. 1a, the method includes the following steps 101 to 102:

In step 101, when the screen brightness needs to be adjusted from the current brightness level to the target brightness level, the transition brightness level is obtained according to the current brightness level and the target brightness level.

The screen brightness corresponding to the transition brightness level is located between the screen brightness corresponding to the current brightness level and the screen brightness corresponding to the target brightness level.

For example, a light sensor is installed on the front panel of the terminal, and the light sensor can monitor the ambient brightness value around the terminal in real time. If the light sensor detects that the ambient brightness value changes, the terminal may determine whether the current brightness level of the screen matches the changed ambient brightness value. Optionally, the terminal is preset with the corresponding relationship between the environmental brightness value and the brightness level, and different environmental brightness values correspond to different brightness levels, that is, the terminal can query the corresponding relationship between the environmental brightness value and the brightness level, and determine the current brightness level. Whether the changed ambient brightness value corresponds. If the current brightness level does not correspond to the changed environmental brightness value, it means that the current brightness level does not match the changed environmental brightness value. At this time, the terminal can obtain the corresponding relationship between the environmental brightness value and the brightness level. The target brightness level corresponding to the subsequent ambient brightness value is determined, and then it is determined that the screen brightness of the terminal needs to be adjusted from the current brightness level to the target brightness level.

Optionally, the terminal may pre-set a transition brightness level between the current brightness level and the target brightness level, and set a generation rule for the transition brightness level, where the generation rule includes a cycle that needs to be displayed cyclically when displaying the corresponding transition brightness level. The first frame number of the first brightness level and the second frame number of the second brightness level, and the arrangement order of the first brightness level of the first frame number and the second brightness level of the second frame number. Wherein, the first brightness level is related to the current brightness level and/or the target brightness level, and the second brightness level is related to the current brightness level and/or the target brightness level. Optionally, the first brightness level may be any brightness level between the current brightness level and the target brightness level and close to the current brightness level, or the first brightness level may be the current brightness level; the second brightness level It can be any brightness level between the current brightness level and the target brightness level and close to the target brightness level, or the second brightness level can be the target brightness level. When the terminal determines that the screen brightness of the terminal needs to be adjusted from the current brightness level to the target brightness level, the terminal can generate the corresponding transition brightness level according to the generation rule of the transition brightness level, that is, according to the preset first brightness level, the second brightness level The brightness level, and the generation rule generates the corresponding transition brightness level.

This embodiment of the present disclosure is described by taking the first brightness level as the current brightness level A and the second brightness level as the target brightness level B as an example. It is assumed that the terminal sets two brightness levels between the current brightness level A and the target brightness level B. The transition brightness levels are respectively the transition brightness level C1 and the transition brightness level C2, and the generation rule for setting the transition brightness level C1 includes that two frames of the current brightness level A and one frame of the target brightness level need to be displayed cyclically when the transition brightness level C1 is displayed. B; The generation rule of the transition brightness level C2 includes that one frame of the current brightness level A and two frames of the target brightness level B need to be displayed cyclically when the transition brightness level C2 is displayed. When the terminal determines that the screen brightness of the terminal needs to be adjusted from the current brightness level to the target brightness level, it can determine that the transition brightness level C1 passes two frames of the current brightness level A and one frame of target brightness according to the generation rules of the two transition brightness levels. Level B is displayed cyclically, that is, the three frames of brightness levels AAB are displayed cyclically. The transition brightness level C2 is displayed cyclically through one frame of current brightness level A and two frames of target brightness level B, that is, three frames of ABB brightness levels are displayed cyclically. At this time, according to the visual residual principle, the screen brightness can be increased or decreased from the current brightness level, the transition brightness level C1, and the transition brightness level C2 to the target brightness level.

Assuming that the terminal sets three transition brightness levels between the current brightness level A and the target brightness level B, which are the transition brightness level C1, the transition brightness level C2, and the transition brightness level C3, and the generation rules for setting the transition brightness level C1 include: When displaying the transition brightness level C1, three frames of the current brightness level A and one frame of the target brightness level B need to be displayed cyclically; the generation rule of the transition brightness level C2 includes that two frames of the current brightness level A need to be displayed cyclically when the transition brightness level C2 is displayed. and two frames of target brightness level B; the generation rule of transition brightness level C3 includes that one frame of current brightness level A and three frames of target brightness level B need to be displayed cyclically when the transition brightness level C3 is displayed. When the terminal determines that the screen brightness of the terminal needs to be adjusted from the current brightness level to the target brightness level, the transition brightness level C1 can be determined according to the generation rule of the three transition brightness levels through three frames of the current brightness level A and one frame of the target brightness level. Level B is displayed cyclically, that is, the four frames of brightness levels of AAAB are displayed cyclically. The transition brightness level C2 is displayed cyclically through two frames of current brightness level A and two frames of target brightness level B, that is, the four frames of brightness levels of AABB are displayed cyclically. Level C3 is displayed cyclically through one frame of current brightness level A and three frames of target brightness level B, that is, four frames of brightness levels of ABBB are displayed cyclically. At this time, the screen brightness can be increased or decreased from the current brightness level, the transition brightness level C1, the transition brightness level C2, and the transition brightness level C3 to the target brightness level B according to the visual residual principle.

In step 102, according to the transition brightness level, the screen brightness is gradually adjusted from the current brightness level until the screen brightness is adjusted to the target brightness level.

For example, after acquiring the display mode of the transition brightness level, the terminal can adjust the screen brightness according to the transition brightness level, that is, after the screen displays the current brightness level, display the transition brightness level according to the screen brightness corresponding to the transition brightness level, After the transition brightness level is displayed, the target brightness level is displayed, and the process of slowly transitioning the screen brightness from the current brightness level to the target brightness level can be completed.

Optionally, taking the setting of two transition brightness levels as an example, it is assumed that the transition brightness level C1 of the two transition brightness levels is displayed cyclically through two frames of the current brightness level A and one frame of the target brightness level B, and the transition brightness level C2 is displayed through a frame of the target brightness level B. The current brightness level A of the frame and the target brightness level B of two frames are displayed cyclically. After displaying the current brightness level A, the terminal can display two frames of the current brightness level A and one frame of the target brightness level B cyclically, that is, the three frames of brightness AAB can be displayed cyclically. level, then display one frame of current brightness level A and two frames of target brightness level B cyclically, that is, the three frames of brightness level ABB are displayed cyclically, and finally the target brightness level B is displayed, which realizes the transition from the current brightness level A to the target brightness level B. of slow excess.

Taking the setting of three transition brightness levels as an example, it is assumed that the transition brightness level C1 of the three transition brightness levels is cyclically displayed through three frames of the current brightness level A and one frame of the target brightness level B, and the transition brightness level C2 is displayed through two frames of the current brightness level. A and two frames of target brightness level B are displayed cyclically. The transition brightness level C3 is displayed cyclically through one frame of current brightness level A and three frames of target brightness level B. After displaying the current brightness level A, the terminal can display three frames of current brightness cyclically. Level A and one frame of target brightness level B, that is, the four frames of AAAB are displayed in a cycle, and then two frames of current brightness A and two frames of target brightness B are displayed in a cycle, that is, the four frames of AABB are displayed in a cycle, and then the cycle is displayed. One frame of current brightness level A and three frames of target brightness level B, that is, four frames of brightness levels of ABBB are displayed cyclically, and finally the target brightness level B is displayed, realizing a slow transition from the current brightness level A to the target brightness level B.

Optionally, when the terminal determines that the screen brightness of the terminal needs to be adjusted from the current brightness level to the target brightness level, it may first determine whether the difference between the screen brightness corresponding to the target brightness level and the screen brightness corresponding to the current brightness level is not. Greater than or equal to the preset brightness threshold, that is, to determine whether brightness jitter occurs when the screen brightness is adjusted from the current brightness level to the target brightness level. If the difference between the screen brightness corresponding to the target brightness level and the screen brightness corresponding to the current brightness level is greater than or equal to the preset brightness threshold, the terminal can obtain the transition brightness level according to the current brightness level and the target brightness level, and according to For the transition brightness level, the screen brightness is gradually adjusted from the current brightness level to the target brightness level; if the difference between the screen brightness corresponding to the target brightness level and the screen brightness corresponding to the current brightness level is less than the preset threshold, that is, the screen brightness Brightness jitter will not occur when adjusting from the current brightness level to the target brightness level. At this time, the terminal can directly adjust the screen brightness from the current brightness level to the target brightness level without displaying a transition brightness level in the middle.

Alternatively, when the terminal determines that the screen brightness of the terminal needs to be adjusted from the current brightness level to the target brightness level, it may first determine whether the target brightness level and the current brightness level are adjacent two brightness levels corresponding to the backlight driving chip. If the target brightness level and the current brightness level are two adjacent brightness levels corresponding to the backlight driving chip, the terminal can obtain a transition brightness level according to the current brightness level and the target brightness level, and according to the transition brightness level, the screen The brightness is adjusted from the current brightness level to the target brightness level; if the target brightness level and the current brightness level are not two adjacent brightness levels corresponding to the backlight driver chip, the terminal can first obtain the target brightness level and the brightness level corresponding to the backlight driver chip. The intermediate brightness level between the current brightness levels, and then the transition brightness level is obtained according to the current brightness level and the intermediate brightness level, and the screen brightness is gradually adjusted from the current brightness level to the intermediate brightness level according to the transition brightness level. The intermediate brightness level and the target brightness level obtain a transition brightness level, and according to the transition brightness level, the screen brightness is gradually adjusted from the intermediate brightness level to the target brightness level.

In the technical solutions provided by the embodiments of the present disclosure, by inserting a transition brightness level between the current brightness level and the target brightness level, the brightness changes during the process of adjusting the brightness of the screen from the current brightness level to the target brightness level are relatively gentle, so that the The effect of uniform brightness transition improves the user experience.

In one embodiment, as shown in FIG. 1b, in step 101, when the screen brightness needs to be adjusted from the current brightness level to the target brightness level, the transition brightness level is obtained according to the current brightness level and the target brightness level, and the transition brightness level can be obtained by Steps 1011 and 1012 implement:

In step 1011, when the screen brightness needs to be adjusted from the current brightness level to the target brightness level, it is determined whether the type of the screen is a preset type.

In step 1012, if the type of the screen is a preset type, the transition brightness level is acquired according to the current brightness level and the target brightness level.

For example, since the brightness jitter that occurs when the screen brightness is adjusted is closely related to the backlight driver chip of the screen, that is, brightness jitter may occur only when the brightness level provided by the backlight driver chip set on the screen is small. When the screen brightness of the terminal is adjusted from the current brightness level to the target brightness level, it is also possible to first determine whether the type of the screen is a preset type. Screens less than or equal to the preset number of levels threshold. If the type of the screen is the preset type, it means that the brightness level provided by the backlight driver chip set on the screen is less than or equal to the preset number of levels threshold, that is to say, only adjusting the screen brightness through the brightness level provided by the backlight driver chip may cause the brightness jitter, then the terminal can obtain the transition brightness level according to the current brightness level and the target brightness level, and gradually adjust the screen brightness from the current brightness level to the target brightness level according to the transition brightness level; if the type of the screen is not The preset type means that the brightness level provided by the backlight driver chip set on the screen is greater than the preset number threshold, which means that adjusting the screen brightness through the brightness level provided by the backlight driver chip is unlikely to cause brightness jitter, and the terminal can The screen brightness is gradually adjusted from the current brightness level to the target brightness level directly through the brightness level provided by the backlight driver chip.

Optionally, if the ambient light does not change, the current brightness level displayed by the terminal matches the current ambient light, and the brightness of the screen does not need to be adjusted. Only when the ambient light changes, so that the current brightness level displayed by the terminal does not match the current ambient light, the terminal needs to adjust the brightness of the screen, that is, the terminal needs to adjust the screen from the current brightness level to the one after the change. The ambient light matches the target brightness level. Specifically, after detecting that the ambient light in the environment where the screen is located, the terminal can determine whether the type of the screen is a preset type, and if the screen is a preset type, obtain a target brightness level that matches the changed ambient light , and then obtain the transition brightness level according to the current brightness level and the target brightness level, and gradually adjust the screen brightness from the current brightness level to the target brightness level according to the transition brightness level. If the screen is of a non-preset type, a target brightness level matching the changed ambient light is obtained, and then the screen brightness can be directly adjusted from the current brightness level to the target brightness level.

In one embodiment, the above transition brightness level may include at least one transition brightness level, and the screen brightness corresponding to different transition brightness levels is different. As shown in FIG. 1c, in step 102, according to the at least one transition brightness level, from the current The brightness level gradually adjusts the screen brightness until the screen brightness is adjusted to the target brightness level, which can be achieved through steps 1021 to 1022:

In step 1021, the duration of each transition brightness level in the at least one transition brightness level is set.

In step 1022, after the display of the current brightness level is completed, the at least one transition brightness level is sequentially displayed according to the duration of each transition brightness level, until the target brightness level is displayed after the display of the last transition brightness level is completed.

For example, if each transition brightness level is displayed for a short time, it may lead to the situation that the screen brightness is adjusted to the target brightness level when the user does not feel the transition brightness level, and the brightness caused by the brightness change cannot be effectively avoided at this time. Therefore, the terminal may also set a duration for each transition brightness level, and the durations of different transition brightness levels may be the same or different, which is not limited in this embodiment of the present disclosure.

Taking the setting of two transition brightness levels as an example, the terminal may set a first duration for the transition brightness level C1 of the two transition brightness levels, and a second duration for the transition brightness level C2. Assuming that the transition brightness level C1 is displayed cyclically through two frames of current brightness level A and one frame of target brightness level B, and the transition brightness level C2 is displayed cyclically through one frame of current brightness level A and two frames of target brightness level B, the terminal is displaying the current brightness level After the brightness level A, two frames of the current brightness level A and one frame of the target brightness level B can be displayed cyclically within the first duration, that is, the three frames of brightness levels AAB can be displayed cyclically within the first duration, and then in the first duration. One frame of the current brightness level A and two frames of the target brightness level B are displayed cyclically within the second duration, that is, the three frames of ABB brightness levels are displayed cyclically within the second duration, and finally the target brightness level B is displayed.

Taking setting three transition brightness levels as an example, the terminal may set a first duration for transition brightness level C1, a second duration for transition brightness level C2, and a third duration for transition brightness level C3 among the three transition brightness levels. Assume that the transition brightness level C1 among the three transition brightness levels is displayed cyclically through three frames of current brightness level A and one frame of target brightness level B, and the transition brightness level C2 is displayed cyclically through two frames of current brightness level A and two frames of target brightness level B , the transition brightness level C3 is displayed cyclically through one frame of current brightness level A and three frames of target brightness level B, then after displaying the current brightness level A, the terminal can display three frames of the current brightness level A and one frame cyclically within the first duration. The frame target brightness level B, that is, the four frames of AAAB brightness levels are displayed cyclically during the first duration, and then two frames of the current brightness level A and the two frames of target brightness level B are displayed cyclically during the second duration, that is, during the second duration. The four frames of brightness levels of AABB are displayed cyclically within a period of time, and then one frame of current brightness level A and three frames of target brightness level B are displayed cyclically within the third duration, that is, the four frames of ABBB are displayed cyclically within the third duration. Finally, when the target brightness level B is displayed, a slow transition from the current brightness level A to the target brightness level B is realized.

It should be noted that the duration of the transition brightness level may be an integer multiple of the number of frames that need to be cycled corresponding to the transition brightness level, that is, the duration of the transition brightness level may be limited by the number of frames.

In the technical solutions provided by the embodiments of the present disclosure, by setting a duration for each transition brightness level, a smooth transition of brightness can be further ensured.
