As shown in fig. 2-4, in which, since the initial brightness curve 100 and the target brightness curve 200 are both mapping curves of ambient light and screen brightness, in the first interval { B _O To the second interval { B } _X Adjusting the initial luminance curve 100 to the target luminance curve 200 within the range of }, in effect adjusting the initial luminance curve 100 to the target luminance curve 200 in a plane having the ambient light level a and the screen luminance B as the abscissa, respectively, said first interval { B } of the screen luminance B _O To the second interval { B } _X The initial luminance curve 100 is adjusted to the target luminance curve 200 within the range of }, which can also be said to be the first interval { B) of the screen luminance B _O To the second interval { B } _X The initial luminance curve 100 is adjusted to the target luminance curve 200 in the corresponding ambient light luminance interval.

The initial screen brightness B _O And the target screen brightness B _X The first section and the second section may also be located in different sections, i.e. the first section and the second section may also be different screen brightness sections, such as: as shown in FIG. 3, the initial screen brightness B _O Located in the interval (B1, B2), saidTarget screen brightness B _X Is located in the interval (B1, B3); or as shown in FIG. 4, the initial screen brightness B _O Located in the interval (B1, B2), the target screen brightness B _X Located in the interval (B2, B4).

The input signal may be an ambient light signal or a signal generated according to a brightness adjustment operation of a user, and the brightness adjustment operation of the user may be pulling a brightness control bar in a UI of an electronic device system.

Wherein, as shown in FIG. 2, the first interval { B _O And the second interval { B } is _X When the two points are the same interval, the starting point and the end point are two end points of the interval respectively; as shown in fig. 3 and 4, the first interval { B } _O And the second interval { B } is _X When the two end points are different intervals, the starting point is any one of the two end points which are farthest from each other between the two intervals, and the end point is the other end point.

Such as: as shown in FIG. 2, the initial screen brightness B _O And the target screen brightness B _X Are both located at (B1, B2), the starting point is (A1, B1) and the end point is (A2, B2) can be determined according to the screen brightness interval (B1, B2) and the initial brightness curve 100, so that the first target brightness curve 201 passes through the starting point (A1, B1), the end point (A2, B2) and the point (a _X ，B _X )。

Such as: as shown in FIG. 3, the initial screen brightness B _O Located in the interval (B1, B2), the target screen brightness B _X Located in the section (B3, B1), the start point (A3, B3) and the end point (A2, B2) can be determined based on the section (B1, B2), the section (B3, B1) and the initial brightness curve, and thus the second target brightness curve 202 passes through the start point (A3, B3), the end point (A2, B2) and the point (a _X ，B _X )。

Referring to fig. 5 and fig. 6 in combination, fig. 5 is a schematic diagram illustrating generation of a fourth target brightness curve according to another embodiment of the application; FIG. 6 is a schematic diagram illustrating generation of a fifth target brightness curve according to other embodiments of the present application.

Wherein, as shown in FIG. 5, the fourth target luminance curve 204 may pass through a start point (A1, B1) and an end point (A4, B4), the start point (A1, B1) and the end point (A4, B4) being in accordance with the first interval { B _O -said second interval { B } _X As well as the initial luminance curve 100, as shown in fig. 6, the fifth target luminance curve 205 may also be determined not to pass through the start point (A1, B1) and the end point (A4, B4) but in the first interval { B) _O And the second interval { B } _X Within the range of }, the whole is directed toward the point (a _X ，B _X ) Gain is performed.

In some embodiments, the brightness interval is divided from a first preset rule based on a degree of adjustment of the initial brightness of the screen. The first preset rule specifies that the brightness interval is (initial brightness of screen-X, target screen brightness+x), X may be any number, and specifically may be determined according to actual needs, where X is a non-negative number when the initial brightness of screen is greater than the target screen brightness, and X is a negative number or 0 when the initial brightness of screen is less than the target screen brightness. Such as: when the initial brightness of the screen is 40 and the target screen brightness is 60 and x=5, the brightness interval determined according to the first preset rule is (35, 65). Thus, the division of the brightness interval is not fixed, but dynamically varies with the degree of adjustment of the initial brightness of the screen.

In other embodiments, the brightness interval is divided based on a second preset rule. The second preset rule may be that the length of each section is the same, for example, the brightness sections are divided according to (0, 10), (10, 20), (20, 30), (30, 40), (40, 50), (50, 60), (60, 70), (70, 80), (80, 90) and (90, 100). It should be noted that, the second preset rule may also be that the length of each section gradually increases, etc., and the brightness sections divided under the second preset rule are fixed and do not dynamically change with the adjustment degree of the initial brightness of the screen.

In some embodiments, the dividing the brightness interval based on the second preset rule includes: the brightness interval corresponds to the sensitivity division of human eyes to the ambient brightness, and the higher the sensitivity of human eyes to the ambient brightness is, the denser the division density is.

According to human eye mechanism and human visual model, subjective brightness perceived by human eye and actual objective brightness are not completely the same, but have a certain corresponding relation. The range of brightness that the human eye can feel (known as the visual range) is extremely wide, from a few thousandths to a few million nits. It is so wide, since it relies on the regulation of the pupil and the photosensitive cells. The pupil adjusts the size according to the intensity of external light, so that the luminous flux emitted to the retina is as moderate as possible. Under strong light and weak light, cone cells and rod cells act respectively, and the sensitivity of the latter is 1 ten thousand times that of the former. The relative brightness perception produced by the human eye for the same actual brightness is different under different brightness environments. For example, for the same lamp, the relative brightness perception that it produces for the human eye is different during the day and night. In addition, when the human eye adapts to a certain ambient brightness, the perceived range will become smaller. For example, when the ambient brightness is 10000 nits in daytime, the human eye can recognize about a brightness range of 200 to 20000 nits, and an ambient brightness lower than 200 nits is perceived as black. In this case, the luminance section may be divided in a luminance range of 200 to 20000 nits, and not divided in a luminance range of less than 200 nits. When the ambient brightness at night is 30 nits, the distinguishable brightness ranges from 1 to 200 nits, and at this time, the ambient brightness of 100 nits causes a rather bright feeling. Only a luminance below 1 nit causes a black feeling. The human eye perceives brightness as an exponential relationship with light intensity, while the physically defined brightness is proportional to light intensity. In this case, the luminance section may be divided in the luminance range of 1 to 200 nit, and the luminance section may not be divided in the luminance range of more than 200 nit.

Therefore, the division in the brightness range with low human eye perception sensitivity is avoided to do invalid work.

In other embodiments, the dividing the brightness interval based on the second preset rule includes: the division is performed based on the slope of the initial brightness curve, and the greater the slope of the initial brightness curve is, the denser the division density is.

The initial brightness curve 100 may be a straight line with the same slope, a plurality of straight lines with different slopes, or a curve (as shown in fig. 7).

The greater the slope of the initial brightness curve, the denser the brightness interval division density is in order to avoid that the target brightness curve has too large a screen brightness abrupt change relative to the initial brightness curve, thereby causing excessive brightness or excessive darkness to require frequent adjustment by a user when the target brightness curve is used to adjust the screen brightness.

In still other embodiments, the dividing the brightness interval based on the second preset rule includes: the brightness interval corresponds to the brightness range in which the sensitivity of human eyes to the ambient brightness and the slope of the initial brightness curve are divided, and the higher the sensitivity of human eyes to the ambient brightness is, the larger the slope of the initial brightness curve is, and the denser the division density is.

In some embodiments, in response to adjustment of the initial screen brightness by the plurality of input signals under different ambient light levels, a section in which the plurality of target screen brightness is located is determined, and a curve in the initial brightness curve within the section in which the plurality of target screen brightness is located is adjusted to obtain a target brightness curve.

Further, the target brightness curve passes through points where a plurality of target screen brightnesses are located, such as: as shown in fig. 8, in the case where the ambient light level is a10, the target screen luminance is B10, and the section where the target screen luminance is located is { B10}; when the ambient light level is a20, the target screen luminance is B20, and the section where the target screen luminance is located is { B20}. The sixth target luminance curve 206 passes through (a 10, B10) and (a 20, B20).

In some embodiments, the brightness adjustment method further comprises: and generating a reset brightness curve by performing gain on the initial brightness curve based on the target brightness curve in response to a change signal of the screen use state, wherein at least part of values of the target brightness curve are adjusted towards the initial brightness curve.

The screen use state change signal comprises any one or more of a signal from a bright screen to a dead screen, a signal from the dead screen to the bright screen, a switching signal of an application program and a signal that the screen use time exceeds a preset value.

After the reset brightness curve is generated, the screen brightness is adjusted according to the reset brightness curve.

In some embodiments, the target luminance curve is adjusted toward the initial luminance curve in the same proportion, specifically, a difference between the target luminance curve and the screen luminance of the initial luminance curve under various environmental luminances may be calculated, then the screen luminance of the target luminance curve under various environmental luminances is moved by a distance of the difference x a first preset coefficient toward a direction approaching the screen luminance of the initial luminance curve corresponding to the same environmental luminance, so as to generate the reset luminance curve, for example, the adjusted initial state is fig. 4 (passing point), but for example, the screen is turned into fig. 6 after the screen is turned into fig. 5 after the screen is turned into fig. 5, and the initial curve is gradually approached as the number of times increases.

The reset luminance profile generated in this way caters to the user's preferences but does not change too quickly on the basis of the initial luminance profile, since the initial luminance profile is generally derived on the basis of studies, the user's personal preferences may be detrimental to health (seeing impaired vision for a long time, etc.).

In some embodiments, the brightness adjustment method further comprises: and acquiring a use scene in which the user is positioned when adjusting the screen brightness. Determining the initial brightness curve based on the usage scenario; when the initial brightness curves are multiple, different initial brightness curves correspond to different use scenes.

In some embodiments, the usage scenario may be divided according to an ambient brightness, for example, the ambient brightness is greater than a preset value and is an outdoor scenario, and the ambient brightness is less than the preset value and is an indoor scenario. Further, the division may be further performed according to a currently used application program and/or a motion state of the current electronic device, for example: the application programs are classified into a reading application program, a game application program, a general application program scene, and the like according to the application programs currently used. And, for example: the electronic equipment is divided into scenes in a motion state or a static state according to the motion state of the current electronic equipment.

Different initial brightness curves are correspondingly set for different scenes, so that a user can have better screen brightness experience under different scenes. Such as: as shown in fig. 9, the initial brightness curve 100a is an outdoor scene and a game scene, the initial brightness curve 100b is an indoor scene, and the initial brightness curve 100c is a night scene and a reading software scene.

In some embodiments, the brightness adjustment method further comprises: and acquiring the screen brightness of a use scene where the user is when the screen brightness is regulated.

And respectively accumulating historical adjustment information of the user on the screen brightness under different use scenes.

And determining the common brightness under different use scenes according to the historical adjustment information under different use scenes.

Further, the determining the common brightness under different usage scenarios according to the history adjustment information under different usage scenarios includes:

and taking the mode in the historical target screen brightness under the same use scene as the common brightness under the use scene, wherein the historical adjustment information comprises the historical target screen brightness.

In some embodiments, the brightness adjustment method further comprises:

acquiring a current use scene;

and adjusting the screen brightness to be the corresponding common brightness according to the current use scene and the corresponding relation between the use scene and the common brightness.

Because different users have different favorite screen brightness under different use scenes, the common brightness of the users under different use scenes is obtained according to the historical adjustment information of the users on the screen brightness under different use scenes, and the screen brightness is automatically adjusted to the common brightness corresponding to the scene according to the current use scene, so that the preference of the screen brightness of different users can be met.

Referring to fig. 10, fig. 10 is a block diagram illustrating an electronic device according to some embodiments of the application.

In the present application, compared to the case that the adjustment of the initial brightness curve is required after the adjustment of the initial brightness of the screen, and after the screen assembly 10 determines the target brightness of the screen, the first processor 11 further needs to obtain a first section in which the initial brightness of the screen is located and a second section in which the target brightness of the screen is located, and adjust the initial brightness curve to be the target brightness curve in a range from the first section to the second section, so that the deformation degree of the target brightness curve relative to the initial brightness curve is reduced, and the adjustment of the brightness curve is kept unchanged in other brightness ranges or the adjustment degree is small, thereby avoiding the overall adjustment of the brightness curve without distinguishing the adjustment degree, and making the targeted adjustment of the screen brightness under a part of the ambient brightness impossible for the user.

The adjustment module 23 adjusts the initial luminance profile to the target luminance profile over the first interval and the second interval. The initial brightness curve and the target brightness curve are both mapping curves of ambient light and screen brightness, and the screen brightness comprises a plurality of brightness intervals.

In the present application, compared to the case that the adjustment of the initial brightness curve is required after the adjustment of the initial brightness of the screen, and after the determination module 21 determines the target brightness of the screen, the second obtaining module 22 further needs to obtain a first section where the initial brightness of the screen is located and a second section where the target brightness of the screen is located, and the adjustment module 23 adjusts the initial brightness curve to the target brightness curve in a range from the first section to the second section, so that the deformation degree of the target brightness curve relative to the initial brightness curve is reduced, and in other brightness ranges, the adjustment of the brightness curve is kept unchanged, or the adjustment degree is small, so that the overall adjustment of the brightness curve without differentiating the adjustment degree is avoided, and the user cannot make the targeted adjustment to the brightness of the screen under a part of the ambient brightness.

The communication module 30 is further configured to send the target brightness curve to a target electronic device, where the target electronic device is any one or a combination of several of an electronic device that sends the current ambient brightness, an electronic device associated with an electronic device that sends the current ambient brightness, and an electronic device located in the same area as the electronic device that sends the current ambient brightness.

In the present application, the second processor 31 further needs to obtain a first section in which the initial screen brightness is located and a second section in which the target screen brightness is located after the communication module 30 receives the target screen brightness sent by the electronic device, and adjusts the initial brightness curve to be the target brightness curve in a range from the first section to the second section, so that the deformation degree of the target brightness curve relative to the initial brightness curve can be reduced, and the adjustment of the brightness curve is kept unchanged in other brightness ranges or is small, thereby avoiding that the brightness curve does not distinguish the adjustment degree and performs the overall adjustment, and the user cannot perform the targeted adjustment on the screen brightness under the partial ambient brightness. The server 500 may send a plurality of electronic devices with a certain correlation to use at the same time according to the target brightness curve generated by adjustment, so that it may be more convenient to unify a plurality of electronic devices with a certain correlation to adjust the screen brightness according to the target brightness curve.
