Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Because the two-dimensional code has a poor display effect, in order to solve the problem, embodiments of the present invention provide a system, a method, and a device for adjusting screen brightness.
In an embodiment of the present invention, referring to fig. 1A, a schematic structural diagram of a screen brightness adjusting system is provided, where the system includes a first electronic device 101 and a second electronic device 102.
The first electronic device 101 is configured to determine the current time of a time zone to which a geographical location of the first electronic device 101 belongs when the two-dimensional code needs to be displayed for the second electronic device 102; determining a target ratio for adjusting the screen brightness of the first electronic device 101 according to the information of the ambient brightness reflected by the current time; according to the target ratio, the screen brightness is adjusted on the basis of the current screen brightness of the first electronic device 101, and the two-dimensional code to be scanned is displayed after the screen brightness is adjusted.
A detailed description of the method for adjusting the screen brightness and displaying the two-dimensional code to be scanned by the first electronic device 101 is presented in the following steps S101 to S103, and will not be detailed here.
And the second electronic device 102 is configured to scan and identify the two-dimensional code to be scanned, which is displayed by the first electronic device 101.
Data is not directly transmitted between the first electronic device 101 and the second electronic device 102 in a wired or wireless signal manner, but the second electronic device 102 can acquire information by scanning the two-dimensional code to be scanned displayed by the first electronic device 101.
Therefore, the screen brightness is adjusted according to the current time, the adjusted screen brightness can accord with the ambient brightness, and the two-dimensional code to be scanned can be clearly displayed, so that the second electronic device can scan the two-dimensional code to be scanned conveniently. The screen brightness does not need to be manually increased by a user, the efficiency of adjusting the screen brightness is improved, and the display effect of the two-dimensional code is improved.
Corresponding to the above system, in another embodiment of the present invention, a screen brightness adjusting method applied to a first electronic device is provided, where the first electronic device is configured to display a two-dimensional code to be scanned for another second electronic device, and the method includes:
determining the current time of a time zone to which the geographical position of the first electronic equipment belongs;
and determining a target proportion for adjusting the screen brightness of the first electronic equipment according to the information of the ambient brightness reflected by the current time.
And adjusting the screen brightness on the basis of the current screen brightness of the first electronic equipment according to the target proportion, and displaying the two-dimensional code to be scanned after the screen brightness is adjusted.
The following describes a method and an apparatus for adjusting screen brightness according to an embodiment of the present invention with specific embodiments. Referring to fig. 1B, an embodiment of the present invention provides a flowchart of a first method for adjusting screen brightness, which is applied to a first electronic device, where the first electronic device is configured to display a two-dimensional code to be scanned for another second electronic device. Specifically, the method includes the following steps S101-S103.
S101: and determining the current time of the time zone to which the geographical position of the first electronic equipment belongs.
In view of the above, in an embodiment of the present invention, the current time of the time zone to which the geographical location of the first electronic device belongs may be obtained by obtaining the system time of the first electronic device.
In another embodiment of the present invention, the time zone to which the first electronic device belongs may also be determined according to the geographic location to which the first electronic device is located, and then the current time of the time zone to which the first electronic device belongs may be determined from the network side through the network.
S102: and determining a target proportion for adjusting the screen brightness of the first electronic equipment according to the information of the ambient brightness reflected by the current time.
Because the time in different time zones at the same time is different, that is, the relative time in different time zones is different for the same absolute time, for example, the time in time zone a is 12:00 at the same time, the time in time zone B is 13:00 at the same time, and the ambient brightness of the environment where the first electronic device located in different time zones is located is also different. For example, at the same time, time zone a is day time, time zone B is night time, and the ambient brightness in time zone a is greater than the ambient brightness in time zone B under normal circumstances. In addition, the ambient brightness in the same time zone is different at different times, for example, in general, the ambient brightness in the daytime in time zone a is greater than the ambient brightness at night. Therefore, the current time of the time zone to which the geographical position of the first electronic device belongs can reflect the ambient brightness of the geographical position of the first electronic device.
Specifically, the ambient brightness at different times may be counted in advance, and then the level of the ambient brightness reflected at different times is determined according to the statistical result. For example, in 24 hours, by counting the ambient brightness at different times per 24 hours, the ambient brightness of 12:00 may be the highest, the ambient brightness of 0:00 may be the lowest, the ambient brightness of 0:00-12:00 gradually increases, and the ambient brightness of 12:00-0:00 gradually decreases for the time of day.
In addition, the ambient brightness reflected at the same time may be different according to the difference of the month, the season, and the like, so that the first corresponding relationship may be adjusted according to the current month or the season, and thus, in different months or seasons, different brightness adjustments may be performed on the screen of the first electronic device, so that the ambient brightness conditions of different months or seasons match.
Moreover, according to the different geographic locations of the first electronic device, the ambient brightness reflected at the same time may also be different, for example, at the same time, the closer the geographic location of the first electronic device is to the equator, the higher the ambient brightness is, so that the first corresponding relationship may be adjusted according to the geographic location of the first electronic device, so that the first electronic devices located at different locations may perform different brightness adjustments on the screen, thereby matching the ambient brightness conditions at different geographic locations.
In an embodiment of the present invention, the adjusting of the screen brightness of the first electronic device may be adjusting the screen brightness to be higher or lower. The higher the ambient brightness reflected by the current time, the higher the target ratio.
When the target proportion is a positive value, the screen brightness of the first electronic device is increased, and when the target proportion is a negative value, the screen brightness of the first electronic device is decreased.
For example, a target ratio of 30% for 8:00, 50% for 12:00, 35% for 15:00, 20% for 0:00, etc.
Further, the target ratio may be: the ratio of the luminance difference divided by the current luminance is: and adjusting the difference value between the brightness of the first electronic equipment before and after the screen brightness.
The target ratio may be: the ratio of the luminance difference divided by the maximum difference is: and the difference value between the highest screen brightness and the current brightness of the first electronic device.
In an embodiment of the present invention, the target ratio may be determined according to a preset first corresponding relationship between time and the target ratio. The first correspondence may be a one-to-one correspondence between time and a target proportion, for example, the target proportion corresponding to 8:00 is 30%, the target proportion corresponding to 12:00 is 50%, and the like, or the first correspondence may be a correspondence between time periods and target proportions, and the target proportions corresponding to time in the same time period are the same, for example, the target proportion corresponding to 8:00-9:00 is 30%, and the target proportion corresponding to 12:00-13:00 is 50%, and the like.
In another embodiment of the present invention, the target ratio may also be determined according to step S102A, which will not be described in detail herein.
S103: and adjusting the screen brightness on the basis of the current screen brightness of the first electronic equipment according to the target proportion, and displaying the two-dimensional code to be scanned after the screen brightness is adjusted.
In an embodiment of the present invention, the target ratio may be multiplied by the current luminance, and the multiplied value may be added to the current luminance to obtain the target luminance. And when the target brightness is larger than the highest screen brightness, determining the target brightness as the highest screen brightness, and adjusting the screen brightness of the first electronic device to the target brightness.
In another embodiment of the present invention, the target ratio may be multiplied by the maximum difference value, and the obtained result is added to the current brightness to obtain a target brightness, and the screen brightness of the first electronic device may be adjusted to the target brightness.
Specifically, the target luminance may be calculated according to the following formula:
bd＝bc+(x-bc)*f(t)
wherein, the above bdRepresenting the above target brightness, bcThe current screen brightness of the first electronic device is represented, x represents the highest screen brightness of the first electronic device, and f (t) represents the target ratio.
Specifically, the current screen brightness may be represented by a number between 0 and 1, where a current screen brightness of 0 indicates that the screen brightness of the first electronic device is the highest screen brightness, and a current screen brightness of 1 indicates that the screen brightness of the first electronic device is the lowest screen brightness. In the above case, X is 1, and b is calculateddAgain with a number between 0 and 1.
The current screen brightness and the maximum screen brightness may be normalized to other ranges such as 0-5, 0-10, etc.
The current screen brightness may be expressed by a specific value of brightness.
As can be seen from the above, since the current time is the current time of the time zone to which the geographical location of the first electronic device belongs, and the time is different and the ambient brightness is different, the current time can reflect the ambient brightness of the environment in which the first electronic device is located, and therefore, the screen brightness is adjusted according to the current time, so that the adjusted screen brightness can be matched with the ambient brightness. The screen brightness does not need to be manually increased by a user, the efficiency of adjusting the screen brightness is improved, and the display effect of the two-dimensional code is improved.
Referring to fig. 2, a flow chart of a second screen brightness adjustment method is provided, and compared with the foregoing embodiment shown in fig. 1B, the step S102 can be implemented by S102A.
S102A: and determining a target ratio for adjusting the screen brightness of the first electronic device according to the time difference between the current time and a preset reference time.
The preset reference time is the time with the highest ambient brightness within a preset statistical time period.
Specifically, the time when the ambient brightness is the highest may be determined after statistics of ambient brightness at different times are performed. The preset statistical time period can be 0:00-12:00, 0: 00-the next day 0:00 and the like.
For example, in the case that the preset statistical time period is 0: 00-0:00 of the next day, the preset reference time may be 12:00 or 14: 00.
Since the reference time is the time at which the ambient brightness is highest within the preset statistical time period, according to the change rule of the ambient brightness, the larger the time difference between the current time and the reference time is, the lower the ambient brightness is, that is, the lower the target proportion is.
In an embodiment of the present invention, the target ratio may be determined according to a preset second corresponding relationship between the time difference and the target ratio. The second correspondence may be a one-to-one correspondence between the time difference and the target ratio, for example, when the time difference is 0, the target ratio is 40%, when the time difference is 3 hours, the target ratio is 20%, when the time difference is 8 hours, the target ratio is-10%, and the like. The second correspondence relationship may be a correspondence relationship between the time difference interval and the target ratio, for example, when the time difference is between 0 and 1 hour, the target ratio is 40%, and when the time difference is between 8 and 9 hours, the target ratio is 20%.
In addition, according to the difference of months, seasons and the like, the ambient brightness reflected at the same time may be different, and the reference time corresponding to the time when the ambient brightness is the highest may also be different, so that the reference time and the second corresponding relation may be adjusted according to the current month or season, and therefore, in different months or seasons, different brightness adjustments may be performed on the screen of the first electronic device, so that the ambient brightness conditions in different months or seasons are matched.
Moreover, according to the different geographic locations of the first electronic device, the ambient brightness reflected at the same time may also be different, and the second corresponding relationship may be adjusted according to the geographic location of the first electronic device, so that the first electronic devices located at different locations can perform different brightness adjustments on the screen, thereby matching the ambient brightness conditions at different geographic locations. In another embodiment of the present invention, the target ratio for adjusting the screen brightness of the first electronic device may also be determined according to the following formula:
Figure BDA0002562629850000101
wherein f (t) represents the target ratio, t represents the current time, b represents the preset reference time, i.e. t-b is the time difference, and a and c are preset parameters.
Specifically, t and b may be represented by decimal numbers, for example, t is 12 in the case of current time being 12:00, and t is 14.5 in the case of current time being 14: 30.
Because the ambient brightness reflected at the same time may be different according to the difference of months, seasons, geographical positions and the like, and the corresponding reference time when the ambient brightness is the highest may also be different, the values of a, b and c can be adjusted to meet different screen brightness adjustment requirements.
In one embodiment of the present invention, when a is 1, b is 12, and c is 3, the above formula is:
Figure BDA0002562629850000102
referring to fig. 3, a schematic diagram of the time versus target ratio relationship is provided.
In fig. 3, the abscissa represents time, and the ordinate represents the target ratio. As can be seen from the figure, the target ratio is normally distributed in a time range of 0 to 24, and since a is 1 and b is 12, the target ratio is the highest and 1 when the current time is 12, and since c is 3, the target ratio is largely changed in a time range of 12 ± 3.
The target proportion calculated according to the formula is larger than 0, so that the target proportion is determined according to the formula, and only the screen brightness can be increased according to the target proportion.
As can be seen from the above, at the reference time, the ambient brightness is the largest, and as can be seen from the change rule of the ambient brightness, the larger the time difference between the current time and the reference time is, the lower the ambient brightness is, and the lower the screen brightness, that is, the lower the target ratio is, which is required to clearly display the two-dimensional code in the screen. The target ratio can be determined based on the time difference.
Referring to fig. 4, a schematic structural diagram of a screen brightness adjusting apparatus is provided, which is applied to a first electronic device, where the first electronic device is configured to display a two-dimensional code to be scanned for another second electronic device, and the apparatus includes:
a time determining module 401, configured to determine a current time of a time zone to which a geographical location of the first electronic device belongs;

and a brightness adjusting module 403, configured to adjust screen brightness based on current screen brightness of the first electronic device according to the target ratio, and display the two-dimensional code to be scanned after the screen brightness is adjusted.
As can be seen from the above, since the current time is the current time of the time zone to which the geographical location of the first electronic device belongs, and the time is different and the ambient brightness is different, the current time can reflect the ambient brightness of the environment in which the first electronic device is located, so that the screen brightness is adjusted according to the current time, and the adjusted screen brightness can be matched with the ambient brightness, so that the two-dimensional code to be scanned can be clearly displayed. The screen brightness does not need to be manually increased by a user, the efficiency of adjusting the screen brightness is improved, and the display effect of the two-dimensional code is improved.
In an embodiment of the invention, the ratio determining module 402 is specifically configured to determine a target ratio for adjusting the screen brightness of the first electronic device according to a time difference between the current time and a preset reference time.
As can be seen from the above, at the reference time, the ambient brightness is the largest, and as can be seen from the change rule of the ambient brightness, the larger the time difference between the current time and the reference time is, the lower the ambient brightness is, and the lower the screen brightness, that is, the lower the target ratio is, which is required to clearly display the two-dimensional code in the screen. The target ratio can be determined based on the time difference.
In an embodiment of the present invention, the ratio determining module 402 is specifically configured to determine a target ratio for adjusting the screen brightness of the first electronic device according to the following formula:
Figure BDA0002562629850000121
wherein f (t) represents the target proportion, t represents the current time, b represents the preset reference time, and a and c are preset parameters.
In an embodiment of the invention, the preset reference time is a time when the ambient brightness is highest within a preset statistical time period.
In an embodiment of the present invention, the brightness adjusting module 403 is specifically configured to:
