Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The adjustment of the screen brightness of the terminal device can affect the display effect of the terminal device, the viewing experience of the user and the like. In order to ensure the display effect and improve the visual experience of a user, the invention can provide the screen brightness adjusting method, which can detect the current environment light intensity value after the received automatic adjusting instruction of the screen brightness, determine the brightness value corresponding to the current environment light intensity value as the target brightness value based on the current environment light intensity value, and then adjust the screen brightness by adopting the preset brightness adjusting step length according to the target brightness value. Therefore, the screen brightness of the terminal equipment can be changed based on the change of the current ambient light intensity value, and the automatic adjustment of the screen brightness is realized.
The following describes a screen brightness adjusting method, a screen brightness adjusting device, a terminal device, and the like provided by the present invention in detail with reference to a plurality of examples.
Fig. 1 is a flowchart of a first embodiment of a screen brightness adjusting method according to the present invention. The screen brightness adjusting method can be realized by the terminal equipment in a software and/or hardware mode. As shown in fig. 1, the method of this embodiment may include:
And after receiving the automatic adjustment instruction of the screen brightness, the terminal equipment can be in an automatic adjustment mode of the screen brightness. The automatic adjustment instruction may be an automatic adjustment instruction input by a user by clicking an adjustment button on the control interface, or may be an automatic adjustment instruction input by a user by voice. Of course, the automatic adjustment command may also be a command received in other forms, which are only some possible examples, and the present invention is not limited thereto.
After receiving the automatic adjustment instruction of the screen brightness, the current ambient light intensity value can be detected in a preset detection period. The detection of the current ambient light intensity value can be detected by a light sensor of the terminal equipment.
That is to say, in the solution of the present invention, the terminal device is in the automatic adjustment mode as long as it receives the automatic adjustment instruction of the screen brightness, and in the automatic adjustment mode, the user does not need to input an adjustment operation, so that the method can detect the current ambient light intensity value by the light-sensitive sensor when the adjustment operation of the user is not received, and then realize automatic adjustment.
Since the terminal device may be in an environment where the ambient light changes constantly, when the current ambient light intensity value is detected, it is further necessary to determine whether the current ambient light is stable according to the current ambient light intensity value and the historical ambient light intensity value within the preset time, that is, whether the fluctuation of the ambient light intensity value detected within the preset time is within a preset range. If the fluctuation of the ambient light intensity value detected within the preset time is within the preset range, the stability of the ambient light of the terminal equipment can be determined, and the currently detected ambient light intensity value can be used as the current ambient light intensity value. If the fluctuation of the ambient light intensity value detected within the preset time is not within the preset range, it can be determined that the ambient light of the terminal device is unstable, and therefore the ambient light intensity value needs to be continuously detected, and whether the ambient light intensity value is stable or not is judged until the detected ambient light intensity value is stable. Therefore, the screen brightness is prevented from changing frequently along with the ambient light when the ambient light changes too frequently, and the visual experience of a user is improved.
And 102, determining the brightness value corresponding to the current environment light intensity value as a target brightness value.
And after the current environment light intensity value is obtained, further determining a target brightness value of the screen according to the current environment light intensity value. Specifically, the target brightness value can be obtained from the current ambient light intensity value based on a preset rule.
For example, the preset rule may be a correspondence between an ambient light intensity value and a screen brightness value. The brightness value corresponding to the current environment light intensity value can be determined as the target brightness value according to the current environment light intensity value and the corresponding relation between the preset environment light intensity value and the screen brightness value. Assuming that the current ambient light intensity value detected in step 101 is 100 unit light intensity values, according to the corresponding relationship between the ambient light intensity value and the screen brightness value, the corresponding screen brightness value is 10 unit brightness values when the ambient light intensity value is 100 unit light intensity values, and the target brightness value is 10 unit brightness values when the current ambient light intensity value is 100 unit light intensity values.
The method may also determine the target brightness value corresponding to the current ambient light intensity value according to other rules, which are only examples and are not described herein again.
And 103, adjusting the screen brightness by adopting a preset brightness adjustment step length according to the target brightness value.
After the target brightness value is obtained, the screen brightness of the terminal device needs to be adjusted to the target brightness value. Specifically, the preset brightness adjustment step length can be adopted to gradually adjust the screen brightness to the target brightness value, so that the jump of the screen brightness is avoided, and the user experience is ensured.
For example, assuming that the current screen brightness value is 15 unit brightness values, since the obtained target brightness value is 10 unit brightness values, the screen brightness value needs to be adjusted from 15 unit brightness values to 10 unit brightness values. Assuming that the brightness adjustment step is 1 unit brightness value, the screen brightness is adjusted to 14 unit brightness values according to the step, and then the adjustment is repeated for 4 times until the screen brightness value is adjusted to 10 unit brightness values.
In addition, after the screen brightness is adjusted, the brightness adjusting control on the user interface can be adjusted, so that the brightness adjusting progress of the brightness adjusting control is the adjusting progress corresponding to the target brightness value, that is, the user interface display and the screen brightness are kept synchronous. Optionally, the brightness adjustment control may be, for example, a brightness adjustment progress bar, or may also be an annular or circular brightness adjustment control.
The screen brightness adjusting method provided in this embodiment may detect a current ambient light intensity value after receiving an automatic adjustment instruction of the screen brightness, determine a brightness value corresponding to the current ambient light intensity value as a target brightness value, and adjust the screen brightness by using a preset brightness adjustment step according to the target brightness value. According to the method, after an automatic adjustment instruction of the screen brightness is received, the current environment light intensity value is detected in an automatic adjustment mode, then the screen brightness of the terminal equipment is adjusted according to the current environment light intensity value, adjustment operation of a user is not needed to be received for adjustment, automatic adjustment of the brightness is achieved, the adjustment effect of the screen brightness is better, and the visual experience of the user is improved.
According to the method, adjustment is not needed according to adjustment operation input by a user, and the screen brightness is adjusted according to the brightness value corresponding to the current environment light intensity value, so that the change of the environment light can quickly act on the screen brightness, the sensitivity to the environment change is higher, the lag of the adjustment effect is avoided, and the user experience is improved. When the screen brightness is adjusted, the screen brightness is adjusted step by step according to the preset brightness adjusting step length, so that sudden change of the screen brightness is avoided, and the user experience is better.
On the basis of the embodiment shown in fig. 1, the invention can also provide a screen brightness adjusting method. Fig. 2 is a flowchart of a second embodiment of a screen brightness adjusting method according to the present invention. As shown in fig. 2, step 102 may include, on the basis of the method shown in fig. 1:
At least one history adjustment brightness value may be stored in the terminal device. The history adjustment brightness value may be a screen brightness value adjusted at least one history time before the current time. Illustratively, the history adjustment brightness value may be input by a user operation. That is, at the historical time, the user inputs the adjustment operation, and the adjustment operation corresponds to a target brightness value, which is the historical adjustment brightness value, and the historical time also has a corresponding ambient light intensity value, which is the historical ambient light intensity value. In this case, the terminal device also stores both the historical ambient light intensity value and the historical adjustment luminance value in the terminal device in a state where the screen luminance is adjusted corresponding to one target luminance value based on the adjustment operation, that is, the correspondence relationship between the historical ambient light intensity value and the historical adjustment luminance value is stored. Therefore, the historical ambient light intensity value corresponding to the historical adjustment brightness value can be determined, and the historical ambient light intensity value may or may not be equal to the current ambient light intensity value. Since the historical ambient light intensity value and the historical adjustment brightness value are determined based on user operation, the historical ambient light intensity value and the historical adjustment brightness value can reflect the use preference of the user.
The terminal device may store a preset corresponding relationship between the ambient light intensity value and the brightness value, where the corresponding relationship may be a one-to-one corresponding relationship, for example, one ambient light intensity value corresponds to one brightness value; or many-to-one correspondence, such as when the ambient light intensity values are within a range, all correspond to the same brightness value. After the current ambient light intensity value is detected in step 101, a brightness value corresponding to the current ambient light intensity value, that is, a first preset brightness value corresponding to the current ambient light intensity value, may be determined according to the preset correspondence.
According to the corresponding relation between the preset environment light intensity value and the brightness value stored in the terminal device, the brightness value corresponding to the historical environment light intensity value, namely the preset second brightness value under the historical environment light intensity value, can be determined. The second brightness value may be greater than the history adjustment brightness value, or the second brightness value may be less than the history adjustment brightness value. When the second brightness value is larger than the historical adjustment brightness value, namely the user makes the screen brightness darker through operation adjustment under the historical environment light intensity value, namely the user's use preference is the darker screen brightness. When the second brightness value is smaller than the historical adjustment brightness value, namely the user makes the screen brightness brighter through operation adjustment under the historical environment light intensity value, namely the user's use preference is the brighter screen brightness.
The historical adjustment brightness value is determined as the target brightness value, and then brightness adjustment is carried out, so that the adjustment of the screen brightness is more symbolic of the use preference of a user, and the visual experience of the user is effectively improved.
Specifically, when the second brightness value is greater than the history adjustment brightness value, the user preference is a darker screen brightness. At this time, if the first brightness value is greater than the history adjustment brightness value and less than the second brightness value, that is, the first brightness value is dark relative to the second brightness value, but the first brightness value is still bright relative to the history adjustment brightness value, that is, the first brightness value does not conform to the screen brightness preferred by the user, the history adjustment brightness value is determined as the target brightness value according to the user's usage preference.
When the second brightness value is smaller than the history adjustment brightness value, that is, the user's usage preference is a bright screen brightness, if the first brightness value is larger than the second brightness value and smaller than the history adjustment brightness value, that is, the first brightness value is bright relative to the second brightness value, but the first brightness value is still dark relative to the history adjustment brightness value, that is, the first brightness value does not conform to the user's preferred screen brightness, then the history adjustment brightness value is determined as the target brightness value according to the user's usage preference.
Optionally, in step 204, if the first brightness value is between the second brightness value and the historical adjustment brightness value, before determining that the historical adjustment brightness value is the target brightness value, the method may further include:
If the first brightness value is not between the second brightness value and the historical adjusted brightness value, proceed to step 205.
When the first brightness value is not between the second brightness value and the historical adjustment brightness value, that is, no historical record related to the current ambient light intensity value is stored in the terminal device. At this time, the brightness value corresponding to the current environment light intensity value can be determined according to the preset corresponding relationship between the environment light intensity value and the brightness value stored in the terminal device, and then the brightness value corresponding to the current environment light intensity value is determined to be the target brightness value.
The following further illustrates this embodiment by way of a more specific example.
If the detected current environment light intensity value is 100 unit light intensity values, according to the preset corresponding relation between the environment light intensity value and the screen brightness value, the corresponding screen brightness value is determined to be 10 unit brightness values when the environment light intensity value is 100 unit light intensity values, namely the first brightness value is 10 unit brightness values. If the user operates the adjustment screen to set the brightness value to 11 unit brightness values when the ambient light intensity value is 90 unit light intensity values, the terminal device will store the history, that is, the historical ambient light intensity value is 90 unit light intensity values, and the corresponding historical adjustment brightness value is 11 unit brightness values. According to the preset corresponding relationship between the environmental light intensity value and the screen brightness value, the screen brightness value corresponding to the historical environmental light intensity value 90 is 9 unit brightness values, i.e. the second brightness value is 9 unit brightness values. The second brightness value 9 is smaller than the history adjustment brightness value 11, that is, the user's usage preference is a bright screen brightness. The first brightness value 10 is greater than the second brightness value 9 and less than the history adjustment brightness value 11, so that 11 unit brightness values of the history adjustment brightness value are determined as a target brightness value, and the screen brightness is adjusted to 11 unit brightness values of the target brightness value.
On the basis of the embodiment shown in fig. 1, the method for adjusting screen brightness according to this embodiment of the present invention includes the following steps: determining a historical environment light intensity value corresponding to the historical adjustment brightness value; determining a preset first brightness value corresponding to the current environment light intensity value; determining a preset second brightness value under the historical environment light intensity value; if the first brightness value is between the second brightness value and the historical adjustment brightness value, determining the historical adjustment brightness value as the target brightness value; and if the first brightness value is not between the second brightness value and the historical adjustment brightness value, determining a preset brightness value corresponding to the current environment light intensity value as the target brightness value. The method can determine the use preference of the user according to the historical adjustment brightness value and determine the target brightness value according to the use preference of the user, so that the screen brightness adjustment can better accord with the use habit of the user, and the visual experience of the user is improved.
On the basis of the embodiment shown in fig. 2, the invention can also provide a screen brightness adjusting method. Fig. 3 is a flowchart of a third embodiment of a screen brightness adjustment method provided by the present invention. As shown in fig. 3, on the basis of the method shown in fig. 2, after step 201, the method may further include:
If the current ambient light level is equal to the historical ambient light level, the following step 302 is performed.
That is, the current ambient light intensity value in step 101 and the historical ambient light intensity value in step 201 are compared to determine whether they are equal, and if they are equal, step 302 is executed.
When the current environment light intensity value is equal to the historical environment light intensity value, that is, the current light intensity value is equal to the historical light intensity value, a historical adjustment brightness value exists under the light intensity value, that is, a screen brightness value preferred by a user under the light intensity value, so that the historical adjustment brightness value can be determined as a target brightness value according to the use preference of the user.
The method for adjusting the screen brightness provided by this embodiment, on the basis of the embodiment shown in fig. 2, may further include: judging whether the current environment light intensity value is equal to the historical environment light intensity value; and determining the historical adjustment brightness value of the user under the current environment light intensity value as a target brightness value. According to the method, when the current environment light intensity value is the same as the historical environment light intensity value, the historical adjustment brightness value is determined as the target brightness value, namely the environment where the terminal equipment is located is the same as the historical environment at the historical moment, the screen brightness is automatically adjusted to the historical value in the environment, so that the screen brightness adjustment is more in line with the use habit of a user, and the user experience is better.
The screen brightness adjusting methods provided by the embodiments shown in fig. 1 to 3 are all automatic adjusting methods, that is, the terminal device is set to be in an automatic screen brightness adjusting mode, and then the terminal device can automatically adjust the screen brightness according to the change of the ambient light. In the automatic adjustment mode, in addition to the terminal device automatically adjusting the screen brightness according to the environmental change, the screen brightness adjustment may be performed by a user operation.
Specifically, under the current environment light intensity value, when the adjustment operation input by the user is received, the brightness value input by the user through the adjustment operation is determined as the target brightness value, if the terminal device is automatically adjusting the screen brightness due to the change of the current environment light intensity value, the automatic adjustment is stopped, and then the screen brightness is adjusted to the target brightness value. Meanwhile, the terminal device can also store the corresponding relation between the current environment light intensity value and the target brightness value of the user adjustment operation, and correspondingly adjust the brightness adjustment control of the user interface, so that the brightness adjustment progress of the brightness adjustment control is the adjustment progress corresponding to the target brightness value, namely the user interface display and the screen brightness are kept synchronous.
The screen brightness adjusting method provided by the embodiment can adjust the screen brightness through user operation besides the terminal device automatically adjusting the screen brightness, thereby ensuring that the adjustment of the screen brightness is always biased to the use preference of a user, and ensuring that the visual experience of the user is better.
