The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

The mobile terminal according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, which have wireless communication functions, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal.
The following describes embodiments of the present application in detail.
Referring to fig. 1, fig. 1 is a schematic flow chart of a display parameter adjusting method disclosed in an embodiment of the present application, and as shown in fig. 1, the display parameter adjusting method includes the following steps.
101, when the mobile terminal is in the automatic display parameter adjusting mode, the mobile terminal obtains the current display parameters and the current detection parameters.
In the embodiment of the present application, the display parameter may include a backlight brightness or a backlight color temperature. The display parameter auto-adjustment mode may include a backlight brightness auto-adjustment mode or a backlight color temperature auto-adjustment mode.
The current display parameter may include a current backlight brightness or a current backlight color temperature, and the current detection parameter may include a current light sensation value or a current color temperature value. The mobile terminal can monitor the current light sensing value through the light sensor and can monitor the current color temperature value through the color temperature sensor.
The optical sensor may also be referred to as a light sensor or an ambient light sensor. The light sensor may be disposed on a front panel of the mobile terminal or may be disposed under a display screen (i.e., light sensing under the screen). The light sensor is used for detecting the light sensation value of the environment where the mobile terminal is located. The light sensation value can be expressed in lux.
The color temperature sensor can be arranged on the front panel of the mobile terminal and can also be arranged under the display screen (namely, the color temperature sensor under the screen). The color temperature sensor is used for detecting the color temperature value of the environment where the mobile terminal is located. Both the color temperature value and the backlight color temperature can be expressed in kelvin (K).
In the backlight brightness automatic adjusting mode, the mobile terminal determines the backlight brightness of the mobile terminal according to the automatic backlight brightness curve; in the backlight color temperature automatic adjusting mode, the mobile terminal determines the backlight color temperature of the mobile terminal according to the automatic backlight color temperature curve.
The backlight brightness of the mobile terminal can be set to be in a backlight brightness automatic adjusting mode or in a backlight brightness manual adjusting mode. In the backlight brightness automatic adjustment mode, the backlight brightness of the mobile terminal may be adjusted according to the change of the obtained ambient light intensity, or may be manually adjusted by the user on the basis of automatic adjustment, and when the automatic adjustment conflicts with the manual adjustment, the manual adjustment is generally used as the standard. In the manual adjustment mode, that is, in the case that the user closes the automatic adjustment, the backlight brightness of the mobile terminal is manually set by the user, and once the backlight brightness is set, the backlight brightness of the mobile terminal is fixed.
The backlight brightness of the mobile terminal can be controlled by a display module, and the display module of the mobile terminal generally includes: the display screen (such as a liquid crystal display screen, an LED display screen, an OLED display screen and the like), the backlight source (such as an LED backlight source), the driving circuit, the connecting piece and the control circuit. For a liquid crystal display screen or an LED display screen, the backlight source is positioned at the back of the display screen, the display screen does not emit light, and the display screen displays graphs or characters which are the result of modulating light generated by the display module group to the backlight source. For a liquid crystal display or LED display, the backlight generally includes a light source (e.g., an LED lamp), a light guide plate (e.g., the light guide plate may be made of acrylic material), an optical film, and a plastic frame. The light source is provided with a light guide plate, and the light guide plate is provided with an optical film. The light guide plate and the optical film can convert light generated by the light source into uniform light. In the embodiment of the present application, adjusting the backlight brightness of the mobile terminal mainly refers to adjusting the brightness of a backlight source.
In the manual backlight brightness adjusting mode, a user can adjust the backlight brightness of the mobile terminal by dragging the backlight progress bar of the mobile terminal.
102, the mobile terminal detects whether the current detection parameter is in an anti-shake interval, wherein the anti-shake interval comprises a stable interval and a fine-tuning interval.
In the embodiment of the application, the anti-shake interval is the anti-shake interval that this application embodiment designed, and this anti-shake interval not only includes stable interval, still includes the fine setting interval, and wherein, stable interval and fine setting interval do not have the coincidence.
The anti-shake interval in the embodiment of the present application may have 1 or at least 1 (2 or more than 2), and each anti-shake interval may include a stable interval and at least one fine-tuning interval.
Referring to fig. 2, fig. 2 is a schematic diagram of a display parameter curve disclosed in an embodiment of the present application, and as shown in fig. 2, an abscissa of the display parameter curve is a detected parameter (e.g., a light sensitivity value or a color temperature value), and an ordinate is a display parameter (e.g., a backlight brightness or a backlight color temperature). The anti-shake interval is divided into a stable interval and two fine-tuning intervals, and the stable interval is located between the two fine-tuning intervals. When the detection parameter is in the anti-shake interval, the change amplitude of the display parameter is smaller. Specifically, when the detected parameter is in the stable region, the display parameter remains unchanged, and when the detected parameter changes in the fine-tuning region, the change range of the display parameter is smaller.
103, if the current detection parameter falls into the fine adjustment interval, the mobile terminal determines a first display parameter corresponding to the current detection parameter according to the target display parameter curve, if the first display parameter is not equal to the current display parameter, the mobile terminal calculates the target display parameter according to the current display parameter and the first display parameter, the display parameter of the mobile terminal is adjusted from the current display parameter to the target display parameter, and the absolute value of the difference value between the target display parameter and the current display parameter is smaller than the absolute value of the difference value between the first display parameter and the current display parameter.
In the embodiment of the application, the target display parameter curve may be an automatic display parameter curve, or may be determined based on the automatic display parameter curve and the historical adjustment record. For example, referring to fig. 2, if the current detection parameter is a2 and falls into the fine tuning interval, the mobile terminal determines that the first display parameter corresponding to the current detection parameter is b2 according to the target display parameter curve. If the current display parameter is b1, the mobile terminal may calculate a target display parameter c2 according to the current display parameter b1 and the first display parameter b2, and adjust the display parameter of the mobile terminal from the current display parameter b1 to the target display parameter c2, wherein | c2-b1| < | b2-b1 |. For another example, referring to fig. 2, if the current detection parameter is a3 and falls into the fine-tuning interval, the mobile terminal determines that the first display parameter corresponding to the current detection parameter is b3 according to the target display parameter curve. If the current display parameter is b1, the mobile terminal may calculate a target display parameter c3 according to the current display parameter b1 and the first display parameter b3, and adjust the display parameter of the mobile terminal from the current display parameter b1 to the target display parameter c3, wherein | c3-b1| < | b3-b1 |.
In the embodiment of the application, the display parameters of the mobile terminal are not directly adjusted from b1 to b2 but from b1 to c2 in the fine adjustment interval, or the display parameters of the mobile terminal are not directly adjusted from b1 to b3 but from b1 to c 3. The display parameters are enabled to change slightly in the fine adjustment interval, the anti-shaking interval can be increased, and the anti-shaking capability is improved. For the display parameter of backlight brightness, the embodiment of the application can improve the display parameter to different degrees in a scene with large change of ambient light intensity, such as a scene with change of the posture of the mobile terminal or a street lamp scene. When the ambient light changes slightly, the backlight brightness of the screen can be adjusted slightly, comfortable brightness is provided under the condition that a user does not sense the ambient light, and the user experience of the automatic brightness function is enhanced.
Optionally, in step 103, the mobile terminal calculates the target display parameter according to the current display parameter and the first display parameter, and may include the following steps:
(11) the mobile terminal calculates the absolute value of the difference between the current display parameter and the first display parameter, and multiplies the absolute value of the difference by an attenuation coefficient to obtain an attenuation difference, wherein the attenuation coefficient is less than 1;
(12) if the first display parameter is larger than the current display parameter, the mobile terminal adds the attenuation difference value to the current display parameter to obtain a target display parameter;
(13) and if the first display parameter is smaller than the current display parameter, the mobile terminal subtracts the attenuation difference from the current display parameter to obtain the target display parameter.
In the embodiment of the present application, the attenuation coefficient may be preset and stored in a memory (e.g., a nonvolatile memory) of the mobile terminal. For example, the attenuation coefficient may be set to 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or the like. The attenuation coefficient of the embodiment of the application is fixed in the whole fine adjustment interval. The embodiment of the application provides a method for calculating a target display parameter, so that the absolute value of the difference between the target display parameter and the current display parameter is smaller than the absolute value of the difference between the first display parameter and the current display parameter. The display parameters are enabled to change slightly in the fine adjustment interval, the anti-shaking interval can be increased, and the anti-shaking capability is improved.
Optionally, the fine tuning interval is divided into N fine tuning subintervals, where N is a positive integer; in step 103, the mobile terminal calculates the target display parameter according to the current display parameter and the first display parameter, which may include the following steps:
(21) if the current detection parameter falls into the first fine tuning subinterval, the mobile terminal determines a first attenuation coefficient corresponding to the first fine tuning subinterval; the first vernier interval is any one of N vernier intervals;
(22) the mobile terminal calculates the absolute value of the difference between the current display parameter and the first display parameter, and multiplies the absolute value of the difference by a first attenuation coefficient to obtain a first attenuation difference, wherein the first attenuation coefficient is less than 1;
(23) if the first display parameter is larger than the current display parameter, the mobile terminal adds the first attenuation difference value to the current display parameter to obtain a target display parameter;
(24) and if the first display parameter is smaller than the current display parameter, the mobile terminal subtracts the first attenuation difference from the current display parameter to obtain the target display parameter.
In the embodiment of the present application, each of the N fine tuning subintervals may correspond to one attenuation coefficient, and different attenuation coefficients may be used in different fine tuning subintervals. Therefore, the anti-shake interval can be further increased, and the anti-shake capacity is improved. For the display parameter being the backlight brightness, a strategy of changing the brightness in the fine adjustment interval can be adopted, so that the backlight brightness can change more stably in the fine adjustment interval.
The attenuation coefficient corresponding to the fine tuning subinterval is described below by taking fig. 3 as an example. Referring to fig. 3, fig. 3 is a schematic diagram of a vernier zone according to an embodiment of the present application. As shown in fig. 3, taking N equal to 6 as an example, the fine tuning interval is divided into 6 fine tuning sub-intervals: subinterval 1, subinterval 2, subinterval 3, subinterval 4, subinterval 5, subinterval 6. For example, the attenuation coefficient corresponding to the subinterval 1 is f1, the attenuation coefficient corresponding to the subinterval 2 is f2, the attenuation coefficient corresponding to the subinterval 3 is f3, the attenuation coefficient corresponding to the subinterval 4 is f5, the attenuation coefficient corresponding to the subinterval 5 is f5, and the attenuation coefficient corresponding to the subinterval 6 is f 6. Wherein f1, f2, f3, f4, f5 and f6 are all less than 1. For example, f1 is set to 0.1, f2 is set to 0.2, f3 is set to 0.3, f4 is set to 0.1, f5 is set to 0.2, f6 is set to 0.3.
Optionally, an attenuation coefficient of the N fine tuning subintervals far from the stable interval is greater than an attenuation coefficient of the N fine tuning subintervals near the stable interval.
The attenuation coefficient of the fine tuning subinterval close to the stable interval is set to be smaller, the attenuation coefficient of the fine tuning subinterval far away from the stable interval is set to be larger, and the display parameter can only change in a small range when the detection parameter changes from the stable interval to the fine tuning subinterval, so that the anti-shaking interval can be further increased, and the anti-shaking capacity is improved. Strategies with different attenuation coefficients can be adopted in the fine adjustment interval, so that the display parameters can change more stably in the fine adjustment interval.
Optionally, the target display parameter curve is determined based on the display parameter automatic adjustment mode and the target historical adjustment record.
And 104, if the current detection parameter falls into the stable interval, the mobile terminal determines a stable value corresponding to the stable interval, and if the stable value is not equal to the current display parameter, the mobile terminal adjusts the display parameter of the mobile terminal from the current display parameter to the stable value corresponding to the stable interval.
In the embodiment of the application, when the detection parameter is in the stable interval, the display parameter of the mobile terminal is fixed at the stable value corresponding to the stable interval.

In this embodiment of the application, the scene parameter may include at least one of a light sensing value, a color temperature value, a foreground application of the mobile terminal, a network state of the mobile terminal, an electric quantity of the mobile terminal, a time interval, and a geographic location of the mobile terminal. The light sensing value can be obtained by a light sensor of the mobile terminal, and the color temperature value can be obtained by a color temperature sensor of the mobile terminal. Foreground application, which refers to an application program currently operated by a user; the network status may include whether to use the data network. Further, if a data network is used, the network status may also include whether a WiFi network or a mobile data network is used, the uplink and downlink rates of the network, the network delay, etc. Further, if the WiFi network is used, the network status may further include a Service Set Identifier (SSID) corresponding to the WiFi network. The power of the mobile terminal may include a percentage of a remaining battery power of the mobile terminal to a total battery power. The time interval includes a time interval in which a time point when the scene occurs is located. The granularity of the time interval can be in hours or minutes. For example, the granularity of the time interval may be 1 hour, 30 minutes, etc., and the examples of the present application are not limited thereto. For example, if the scene occurs at 18 o ' clock and 20 min, the time interval is 18 o ' clock to 19 o ' clock. The geographic location may include latitude and longitude information, and the geographic location of the mobile terminal may be obtained through a Global Positioning System (GPS) location of the mobile terminal.
Alternatively, the scene parameters to be considered may be different for different display parameters. For example, for the scene parameter being backlight brightness, the scene parameter to be considered may include a light sensation value, a foreground application of the mobile terminal, a network state of the mobile terminal, an electric quantity of the mobile terminal, a time interval, and a geographic location of the mobile terminal; for the scene parameter being the backlight color temperature, the scene parameter to be considered may include a color temperature value, a foreground application of the mobile terminal, a network state of the mobile terminal, an electric quantity of the mobile terminal, a time interval, and a geographic location of the mobile terminal.
402, the mobile terminal determines a target scene parameter with the highest similarity to the current scene parameter in the historical manual adjustment set and a corresponding target similarity, wherein the target scene parameter is a scene parameter contained in a target historical adjustment record in the historical manual adjustment set.
In an embodiment of the present application, the historical manual adjustment set may include at least one historical adjustment record, and each historical adjustment record includes a historical scene parameter and a corresponding historical display parameter value. And the historical display parameter value is the value of the display parameter manually adjusted by the user in the historical scene corresponding to the historical scene parameter.
The mobile terminal can respectively calculate the similarity between each historical scene parameter in each historical adjustment record in the historical manual adjustment set and the current scene parameter, and obtain the target scene parameter with the highest similarity to the current scene parameter in the historical manual adjustment set and the corresponding target similarity. And the target similarity is the similarity between the current scene parameter and the target scene parameter.
Optionally, in step 402, the mobile terminal determines a target scene parameter with the highest similarity to the current scene parameter in the historical manual adjustment set and a corresponding target similarity, which may specifically include the following steps:
(31) the mobile terminal calculates the similarity between each scene parameter in the historical manual adjustment set and the current scene parameter through a similarity algorithm;
(32) the mobile terminal determines the scene parameter with the highest similarity to the current scene parameter in the historical manual adjustment set as the target scene parameter, and determines the similarity between the current scene parameter and the target scene parameter as the target similarity.
In the embodiment of the application, the similarity calculation method may use a distance function to calculate, where the distance function may include one of an euclidean distance function, a cosine distance function, a hamming distance function, and a manhattan distance function.
Each scene parameter in the historical manual adjustment set can be converted into a vector, the current scene parameter can also be converted into a vector, and the similarity between each scene parameter in the historical manual adjustment set and the current scene parameter can be calculated by calculating the similarity between the two vectors. The dimensions (or number of bits) of the two vectors may be the same or different.
For example, for the display parameter being backlight brightness, the scene parameters include a light sensation value, a foreground application of the mobile terminal, a network status of the mobile terminal, a power level of the mobile terminal, a time interval, and a geographic location of the mobile terminal. If a historical scene parameter is specifically: the light sensation value is 1000lux, the foreground application of the mobile terminal is application A (a certain social application), the network state of the mobile terminal is a mobile data network, the residual electric quantity of the mobile terminal is 50%, the time interval is noon (11: 00-1: 00), and the geographic position of the mobile terminal is (longitude: +111.11, latitude: + 42.13); the current scene parameters are specifically: the light sensation value is 1200lux, the foreground application of the mobile terminal is application B (a certain game application), the network state of the mobile terminal is a WiFi data network, the residual capacity of the mobile terminal is 90%, the time interval is unitary (17: 00-19: 00), and the geographic position of the mobile terminal is (longitude: +111.11, latitude: + 42.13). The mobile terminal may convert a certain item of the scene parameter into a corresponding numerical value, for example, the light sensation value is 1000lux to 5, and the light sensation value is 1200lux to 6; application a converts to 3 and application B converts to 10; the mobile data network is converted into 0, and the WiFi data network is converted into 1; the residual capacity is converted into 5 when the residual capacity is 50 percent, and is converted into 9 when the residual capacity is 90 percent; converting the time interval into 7 at noon and 10 at unitary time; the geographical position (longitude: +111.11, latitude: +42.13) of the mobile terminal is converted into (8, 5), then the parameter vector corresponding to the historical scene parameter is (5, 3, 0, 5, 7, 8, 5), and the parameter vector corresponding to the current scene parameter is (6, 10, 1, 9, 10, 8, 5).
It should be noted that the above example is only one possible example, and the embodiment of the present application may adjust the value corresponding to the vector converted by each item in the scene parameter according to the situation.
Optionally, the mobile terminal calculates the similarity between each scene parameter in the historical manual adjustment set and the current scene parameter through an euclidean distance calculation formula.
Specifically, the mobile terminal obtains a parameter vector corresponding to each scene parameter in the historical manual adjustment set, obtains a parameter vector corresponding to the current scene parameter, respectively calculates the Euclidean distance between the parameter vector corresponding to each scene parameter and the parameter vector corresponding to the current scene parameter according to an Euclidean distance calculation formula, and determines the similarity between each scene parameter in the historical manual adjustment set and the current scene parameter according to the calculated Euclidean distance.
For example, the parameter vector corresponding to the first historical scene parameter in the historical manual adjustment set is (x)1，y1) The parameter vector corresponding to the current scene parameter is (x)2，y2) Wherein the first historical scene parameter isOne of all scene parameters in the set is adjusted manually historically. The mobile terminal may calculate the euclidean distance between the parameter vector corresponding to the first historical scene parameter and the parameter vector corresponding to the current scene parameter according to the following euclidean distance calculation formula:
Figure BDA0002336955180000111
wherein d is the calculated euclidean distance. The larger the Euclidean distance is, the smaller the similarity between the first historical scene parameter and the current scene parameter is, and the smaller the Euclidean distance is, the larger the similarity between the first historical scene parameter and the current scene parameter is.
Optionally, the mobile terminal calculates the similarity between each scene parameter in the historical manual adjustment set and the current scene parameter through a cosine distance calculation formula.
Specifically, the mobile terminal obtains a parameter vector corresponding to each scene parameter in the historical manual adjustment set, obtains a parameter vector corresponding to the current scene parameter, respectively calculates the cosine distance between the parameter vector corresponding to each scene parameter and the parameter vector corresponding to the current scene parameter according to a cosine distance calculation formula, and determines the similarity between each scene parameter in the historical manual adjustment set and the current scene parameter according to the calculated cosine distance.
For example, the parameter vector corresponding to the second historical scene parameter in the historical manual adjustment set is (a)1，a2，a3，a4，a5) The parameter vector corresponding to the current scene parameter is (b)1，b2，b3，b4，b5) Wherein the second historical scene parameter is one of all scene parameters in the historical manual adjustment set. The mobile terminal may calculate the cosine distance between the parameter vector corresponding to the second historical scene parameter and the parameter vector corresponding to the current scene parameter according to the following cosine distance calculation formula:
Figure BDA0002336955180000121
and P is the cosine distance between the parameter vector corresponding to the second historical scene parameter and the parameter vector corresponding to the current scene parameter, namely the similarity between the second scene parameter and the current scene parameter. The value of P is between-1 and 1, and the larger the value of P is, the higher the similarity of the two is. When the value of P is 1, the similarity between the two is the highest, and when the value of P is-1, the similarity between the two is the lowest.
Optionally, the mobile terminal calculates the similarity between each scene parameter in the historical manual adjustment set and the current scene parameter through a hamming distance calculation formula.
Specifically, the mobile terminal obtains a parameter vector corresponding to each scene parameter in the historical manual adjustment set, obtains a parameter vector corresponding to the current scene parameter, respectively calculates a hamming distance between the parameter vector corresponding to each scene parameter and the parameter vector corresponding to the current scene parameter according to a hamming distance calculation formula, and determines the similarity between each scene parameter in the historical manual adjustment set and the current scene parameter according to the calculated hamming distance.
For example, the parameter vector corresponding to the third historical scene parameter in the historical manual adjustment set is (c)1，c2，c3，c4，c5，c6，c7，c8，c9，c10) The parameter vector corresponding to the current scene parameter is (d)1，d2，d3，d4，d5，d6，d7，d8，d9，d10) Wherein the third historical scene parameter is one of all scene parameters in the historical manual adjustment set. The parameter vector corresponding to the scene parameter of the third history is 10 bits, the parameter vector corresponding to the current scene parameter is 10 bits, and each bit of the parameter vector corresponding to the scene parameter of the third history is compared with each bit of the parameter vector corresponding to the current scene parameter to determine whether the bits are the same (i.e., c is compared respectively)1And d1Whether they are the same, c2And d2Whether they are the same, c3And d3Whether they are the same, c4And d4Whether they are the same, c5And d5Whether they are the same, c6And d6Whether they are the same, c7And d7Whether they are the same, c8And d8Whether they are the same, c9And d9Whether they are the same, c10And d10Whether the data are the same or not) is judged, if so, the Hamming distance corresponding to the bit is 0, if not, the Hamming distance corresponding to the bit is 1, the Hamming distances of all the bits are added to obtain the final Hamming distance between the parameter vector corresponding to the third history scene parameter and the parameter vector corresponding to the current scene parameter, and the final Hamming distance is 0-10. The larger the final Hamming distance is, the lower the similarity is; the smaller the final hamming distance, the higher its similarity.
Optionally, before performing step (32), the following steps may also be performed:
(41) the mobile terminal detects whether the number of historical adjustment records in the historical manual adjustment set is greater than or equal to a second threshold value;
(42) if the number of the historical adjustment records in the historical manual adjustment set is larger than or equal to the second threshold value, the mobile terminal executes the step (32).
(43) And if the number of the historical adjustment records in the historical manual adjustment set is smaller than a second threshold value, the mobile terminal adjusts the display parameters of the mobile terminal according to the automatic display parameter curve.
In the embodiment of the present application, the second preset threshold may be preset and stored in a memory (e.g., a non-volatile memory) of the mobile terminal. For example, the second preset threshold may be set equal to 20. The size of the second preset threshold can be determined according to actual conditions, generally speaking, the larger the second preset threshold is set, the more the subsequently generated new display parameter curve conforms to the manual regulation habit of the user, and the reliability is higher. The set time is too large, so that the repeated manual adjustment times of the user can be increased, and the user experience is influenced. If the setting is too small, the reliability of the subsequently generated new display parameter curve is relatively low.
According to the method and the device, the scene parameter with the highest similarity to the current scene parameter is determined as the target scene parameter from the historical manual adjustment set only when the number of the historical adjustment records in the historical manual adjustment set is larger than or equal to the second threshold, and the similarity between the current scene parameter and the target scene parameter is determined as the target similarity. Therefore, the follow-up generated new display parameter curve is more in line with the manual adjustment habit of the user, the reliability is higher, the repeated adjustment of the display parameters by the user is avoided, and the use experience of the user is improved.
And 403, if the similarity of the target is greater than or equal to the first threshold, the mobile terminal acquires a target display parameter value included in the target historical adjustment record, and generates a target display parameter curve according to the target scene parameter, the target display parameter value and the automatic display parameter curve, wherein the automatic display parameter curve is a corresponding display parameter curve in the automatic display parameter adjustment mode.
In the embodiment of the application, the target similarity is greater than or equal to the first threshold, which indicates that the current scene parameter is closer to the target scene parameter, and the mobile terminal may generate the target display parameter curve according to the target scene parameter, the target display parameter value and the automatic display parameter curve.
The first threshold may be preset and stored in a memory (e.g., a non-volatile memory) of the mobile terminal.
The mobile terminal may re-fit the automatic display parameter curve according to the target scene parameters and the target display parameter values, so that the generated target display parameter curve passes through the data points corresponding to the target scene parameters, and the target display parameter curve is smooth, that is, the target display parameter curve is conductive everywhere. The abscissa of the data point corresponding to the target scene parameter includes a light sensation value or a color temperature value in the target scene parameter, and the ordinate of the data point corresponding to the target scene parameter includes a target display parameter value.
The following description will take the display parameter as the backlight brightness, and the scene parameter includes the light sensation value, the foreground application of the mobile terminal, the network state of the mobile terminal, the power of the mobile terminal, the time interval, and the geographic location of the mobile terminal as examples.
Referring to fig. 5, fig. 5 is a schematic diagram of generating a target backlight luminance curve according to an embodiment of the present disclosure. As shown in fig. 5, the graph at the upper left corner is an automatic backlight brightness graph, and the graphs at the lower left corner, the upper right corner and the lower right corner are target backlight brightness graphs generated based on three different history adjustment records, respectively. In the figure, the abscissa is the light sensation value, the ordinate is the backlight luminance, the curve with thinner lines is the automatic backlight luminance curve, and the curve with thicker lines is the target backlight luminance curve. Black points in the automatic backlight brightness curve chart and the target backlight brightness curve chart are historical adjustment records, each black point represents one historical adjustment record, the abscissa of each black point represents the light sensation value corresponding to the time point of the historical adjustment record, and the ordinate of each black point represents the backlight brightness adjusted by the user and recorded in the historical adjustment record. P1, P2 and P3 in FIG. 5 represent three history adjustment records, respectively. The upper right-hand graph represents the target backlight luminance graph generated based on P1, the lower left-hand graph represents the target backlight luminance graph generated based on P2, and the lower right-hand graph represents the target backlight luminance graph generated based on P3.
It should be noted that, in the upper left corner of fig. 5, only three black dots are exemplarily drawn to illustrate the historical adjustment records, the number of the historical adjustment records theoretically only needs to be 1, may also be more than 3, may also be more than 20, and the like, and the embodiment of the present application is not limited.
Wherein, after performing step 403, the mobile terminal may perform steps 404 to 407.
Optionally, after the step 402 is executed, the following steps may also be executed:
and if the target similarity is smaller than the first threshold, the mobile terminal determines that the automatic display parameter curve is the target display parameter curve.
After the mobile terminal determines that the automatic display parameter curve is the target display parameter curve, steps 404 to 407 may be further performed.
If the target similarity is smaller than the first threshold, which indicates that the historical manual adjustment set does not have scene parameters which are similar to the current scene parameters, the mobile terminal does not refer to the historical adjustment record, takes the automatic display parameter curve as a target display parameter curve, and directly adjusts the display parameters of the mobile terminal by adopting the automatic display parameter curve in the subsequent steps 404 to 407.
According to the method and the device, the target display parameter curve can be generated according to the historical manual adjustment record of the user, the target display parameter curve combines the parameters of manual adjustment of the historical scene closest to the current scene on the basis of automatically displaying the parameter curve, so that the target display parameter curve better meets the display parameter adjustment requirement of the current scene of the user, the situation of repeated manual adjustment is avoided, the adjustment effect of the display parameters is improved, and further the user experience is improved.
Optionally, before performing step 401, the following steps may also be performed:
(51) the mobile terminal detects a manual adjustment operation for a display parameter when the mobile terminal is in an automatic adjustment mode for the display parameter.
(52) The mobile terminal obtains the display parameter value adjusted by the manual adjustment operation, and obtains the scene parameter corresponding to the manual adjustment operation.
(53) And the mobile terminal records the display parameter value and the scene parameter as a historical adjustment record in the historical manual adjustment set.
The mobile terminal detects a manual adjustment operation for the display parameter, and specifically includes: the mobile terminal detects a drag operation for a slider in the display parameter progress bar.
Wherein, the display parameter progress bar may comprise a backlight brightness progress bar or a backlight color temperature progress bar.
For example, for the backlight brightness progress bar, the user may adjust the slider in the backlight brightness progress bar from a first position to a second position, where the backlight brightness value corresponding to the first position is the backlight brightness value determined according to the automatic backlight brightness curve, and the backlight brightness value corresponding to the second position is the backlight brightness value adjusted by the user through the manual adjustment operation.
The manual adjusting operation may include an operation of manually adjusting the brightness of the backlight or an operation of manually adjusting the color temperature of the backlight. The display parameter value of the operation of manually adjusting the backlight brightness is the backlight brightness value adjusted by the manual adjusting operation of the user, and the display parameter value of the operation of manually adjusting the backlight color temperature is the backlight color temperature value adjusted by the manual adjusting operation of the user.
In an embodiment of the present application, the historical manual adjustment set may include at least one historical adjustment record, and each historical adjustment record includes a historical scene parameter and a corresponding historical display parameter value.
Steps (51) to (53) in the embodiment of the present application are specific procedures of recording the historical adjustment records in the historical manual adjustment set.
Optionally, before performing step (53), the following steps may also be performed:
(61) the mobile terminal calculates a corresponding automatic display parameter value according to the automatic display parameter curve;
(62) the mobile terminal calculates whether the difference value between the display parameter value adjusted by the manual adjustment operation and the automatic display parameter value is smaller than or equal to the target difference value corresponding to the scene parameter corresponding to the manual adjustment operation;
(63) if the difference between the display parameter value adjusted by the manual adjustment operation and the automatic display parameter value is smaller than or equal to the target difference, the mobile terminal executes step (53).
(64) If the display parameter value adjusted by the manual adjustment operation and the automatic display parameter value are larger than the target difference value, the mobile terminal does not record the display parameter value and the scene parameter as a historical adjustment record in a historical manual adjustment set.
In the embodiment of the present application, the mobile terminal calculates the corresponding automatic display parameter value according to the automatic display parameter curve, including: if the display parameter is backlight brightness, the mobile terminal calculates an automatic backlight brightness value corresponding to a light sensation value in the scene parameter corresponding to the manual adjustment operation according to the automatic backlight brightness curve; and if the display parameter is the backlight color temperature, the mobile terminal calculates an automatic backlight color temperature value corresponding to the color temperature value in the scene parameter corresponding to the manual adjustment operation according to the automatic backlight color temperature curve.
After each manual adjustment operation, the mobile terminal may calculate whether a difference between the display parameter value adjusted by the manual adjustment operation and the automatic display parameter value is less than or equal to a target difference corresponding to the scene parameter corresponding to the manual adjustment operation. In some cases, if the difference between the manually adjusted value of the user and the automatically displayed parameter value calculated by the automatically displayed parameter curve is large, the manually adjusted value of the display parameter and the scene parameter are determined to be invalid and are not recorded in the historical manually adjusted set. The situation that the generated new display parameter curve does not accord with the use habit of the user due to manual error adjustment or malicious manual adjustment of the user is avoided.
The maximum difference value between the value allowed to be manually adjusted by the user and the value of the automatic display parameter calculated by the automatic display parameter curve can be the same or different when the mobile terminal is in different scenes. For example, in an outdoor scene, a larger difference may be allowed, and in a nighttime scene, a smaller difference may be allowed. The scene in which the mobile terminal is located may be determined according to scene generation. The difference values corresponding to different scene parameters may be pre-stored in a memory (e.g., a non-volatile memory) of the mobile terminal.
404, when the mobile terminal is in the automatic display parameter adjustment mode, the mobile terminal obtains the current display parameters and the current detection parameters.
405, the mobile terminal detects whether the current detection parameter is in an anti-shake interval, where the anti-shake interval includes a stable interval and a fine-tuning interval.
And 406, if the current detection parameter falls into the fine-tuning interval, the mobile terminal determines a first display parameter corresponding to the current detection parameter according to the target display parameter curve, if the first display parameter is not equal to the current display parameter, the mobile terminal calculates the target display parameter according to the current display parameter and the first display parameter, adjusts the display parameter of the mobile terminal from the current display parameter to the target display parameter, and the absolute value of the difference between the target display parameter and the current display parameter is smaller than the absolute value of the difference between the first display parameter and the current display parameter.
And 407, if the current detection parameter falls into the stable interval, the mobile terminal determines a stable value corresponding to the stable interval, and if the stable value is not equal to the current display parameter, the mobile terminal adjusts the display parameter of the mobile terminal from the current display parameter to the stable value corresponding to the stable interval.
In this embodiment, the specific implementation of steps 404 to 407 may refer to steps 101 to 104 shown in fig. 1, which is not described herein again.
According to the embodiment of the application, the target display parameter curve can be generated according to the historical manual adjustment records of the user, and as the historical manual adjustment records are selected from the historical real adjustment records of the user, some conjectured or fused unreal manual adjustment records cannot appear, so that the historical adjustment habit of the user is better met. The target display parameter curve combines the parameters of manual adjustment of the historical scene closest to the current scene on the basis of automatically displaying the parameter curve, so that the target display parameter curve better meets the adjustment requirement of the display parameters of the current scene of the user, the situation of repeated manual adjustment is avoided, the adjustment effect of the display parameters is improved, and further the user experience is improved.
