With the foregoing drawings in mind, certain embodiments of the disclosure have been shown and described in more detail below. These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.
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, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the disclosure provides a backlight adjusting method, which can be executed by a backlight adjusting device, and the device can be arranged in terminal equipment with a screen display function and logic processing capability, such as a mobile phone. Referring to fig. 1, fig. 1 is a flow chart illustrating a first embodiment of a backlight adjusting method according to an exemplary embodiment, as shown in fig. 1, the method includes the following steps:
in step 101, when a screen wakeup operation is detected, it is detected whether a value of a jitter time parameter in a current backlight adjustment configuration parameter is greater than a first preset threshold, wherein if so, step 102 is executed.
The screen wakeup operation in this embodiment refers to an operation of waking up a screen of a terminal device from a screen lock state or a screen sleep (black screen) state to a display state. The specific execution mode of the specific screen wakeup operation may refer to an existing wakeup execution mode, and is not described in this embodiment again.
In this embodiment, the first preset threshold may be set as required, when the value of the jitter time parameter is greater than the first preset threshold, a relatively long time is required for adjusting the backlight brightness of the screen from the low brightness or the black screen state in the screen lock or the screen sleep state to the brightness suitable for the ambient brightness, when the value of the jitter time parameter is less than or equal to the first preset threshold, a relatively short time is required for adjusting the backlight brightness of the screen from the low brightness or the black screen state in the screen lock or the screen sleep state to the brightness suitable for the ambient brightness, the specific required time in the actual scene depends on the size of the first preset threshold, and the relationship between the speed of backlight brightness adjustment and the specific value of the jitter time parameter may refer to the prior art, which is not described in this embodiment again.
In step 102, if the value of the jitter time parameter is greater than a first preset threshold, the value of the jitter time parameter is updated to any value less than or equal to the first preset threshold.
When the value of the jitter time parameter is greater than the first preset threshold, the backlight brightness of the screen is adjusted from the low brightness or the black screen state in the screen locking or screen sleeping state to the brightness adaptive to the ambient brightness, which requires a relatively long time, so that the time for maintaining the low brightness of the screen is long, which is not good for the user experience.
In step 103, the backlight brightness of the screen is adjusted at a corresponding speed based on the updated value of the jitter time parameter.
In this embodiment, when the screen wake-up operation is detected, whether the value of the jitter time parameter in the current backlight adjustment configuration parameter is greater than a first preset threshold is detected, if the value of the current jitter time parameter is greater than the first preset threshold, the value of the jitter time parameter is updated to any number that is less than or equal to the first preset threshold, and the backlight brightness of the screen is adjusted at a corresponding speed based on the updated value of the jitter time parameter, so that the purpose of flexibly adjusting the specific value of the jitter time parameter based on the use scene is achieved, when the screen is woken up, the time that the screen keeps low brightness at the wake-up initial stage is not too long due to the fact that the value of the jitter time parameter is too large, and user experience is improved.
Fig. 2 is a flowchart illustrating a second embodiment of a backlight adjusting method according to an exemplary embodiment, as shown in fig. 2, based on the embodiment of fig. 1, the method includes:
in step 201, when the screen wakeup operation is detected, it is detected whether a value of a jitter time parameter in the current backlight adjustment configuration parameter is greater than a first preset threshold.
In step 202, if the value of the jitter time parameter is greater than a first preset threshold, the value of the jitter time parameter is updated to any value less than or equal to the first preset threshold.
In step 203, the backlight brightness of the screen is adjusted at a corresponding speed based on the updated value of the jitter time parameter.
In step 204, if it is detected that the screen is always awake for a preset time period after the screen is awake, the value of the jitter time parameter is updated to a second preset threshold, where the second preset threshold is greater than the first preset threshold.
When the screen is awakened, in order to enable the backlight brightness of the screen to reach the backlight brightness adaptive to the environment as soon as possible, the jitter time parameter corresponding to the screen is set to be any value smaller than or equal to the first preset threshold value. Since this value is small, when the user continuously uses the terminal device, the terminal device may frequently adjust the backlight brightness of the screen due to the change of the ambient light condition, which has an adverse effect on the user experience. In order to improve the user experience, in this embodiment, when it is detected that the screen is always awake for a preset time period after waking up, it is determined that the user is continuously using the terminal device, where the optional operations include, but are not limited to, the following:
in a possible implementation manner, the value of the jitter time parameter is directly set to a second preset threshold greater than the first preset threshold, so as to reduce the frequency of backlight brightness adjustment and enhance the user experience.
In another possible implementation manner, before the value of the jitter time parameter is set to the second preset threshold that is greater than the first preset threshold, the light intensity change frequency of the ambient environment within the preset time duration may be obtained first, and if the light intensity change frequency of the ambient environment within the preset time duration is higher than the third preset threshold, the light intensity change frequency of the current scene is defaulted to be faster, which is not suitable for frequently adjusting the backlight brightness of the screen. At this time, the value of the jitter time parameter is updated to a second preset threshold value larger than the first preset threshold value.
In another possible implementation manner, before the value of the jitter time parameter is set to the second preset threshold greater than the first preset threshold, the light intensity variation range of the ambient environment within the preset time length may be obtained first, and if the light intensity variation range of the ambient environment within the preset time length is smaller than the fourth preset threshold, it is determined that the current ambient light intensity variation is not large, and the backlight brightness of the screen does not need to be adjusted frequently, and at this time, the value of the jitter time parameter is updated to the second preset threshold greater than the first preset threshold.
In another possible implementation manner, based on a combination of the second and third possible implementation manners, when the light intensity variation frequency of the ambient environment within the preset time length is higher than a third preset threshold, and the light intensity variation range of the ambient environment within the preset time length is smaller than a fourth preset threshold, the value of the jitter time parameter is updated to a second preset threshold that is larger than the first preset threshold.
In the embodiment, when the screen is detected to be always kept in the awakening state within the preset time length after the screen is awakened, the adjustment frequency of the screen backlight brightness during continuous use of the user is reduced by increasing the value of the jitter time parameter, and the user experience is improved.
