Technical problem
An electronic device having a function of automatically controlling the brightness of a display may identify a brightness value mapped to external illuminance from initially inputted brightness data and determine the brightness of the display from the identified brightness value. Furthermore, the electronic device may learn the brightness of the display according to the usage pattern of the user, instead of simply controlling the brightness according to the initial input value.
However, the conventional electronic device cannot quickly learn the brightness desired by the user and cannot immediately apply the learned value, thereby failing to provide the brightness of the display optimized for the use mode of the user in real time.
Certain embodiments of the present disclosure may provide an efficient learning method when an electronic device is configured to learn a brightness desired by a user as described above. This efficient learning method can save time or battery life.

A method of controlling brightness by an electronic device may include identifying illuminance information from an illuminance sensor, configuring a brightness of a display to a first brightness based on the illuminance information and the brightness data, changing the brightness of the display to a second brightness based on a user input, acquiring event information for an operation of changing the brightness of the display, reconfiguring brightness data stored in a memory based on the event information, and determining the brightness of the display according to a brightness value mapped to an illuminance value identified by the illuminance sensor in the reconfigured brightness data.
Advantageous effects of the invention
According to various embodiments, an electronic device capable of learning display brightness considering a time for which a user maintains a specific brightness and a method of controlling brightness by the electronic device may be provided.
According to some embodiments, a high weighting value may be assigned when a user holds a particular luminance for a long period of time, and a low weighting value may be assigned when the user temporarily changes luminance and holds luminance for a short period of time. Accordingly, the brightness variation of the user can be reflected by the calculated weighting value, and the learning of the usage pattern of the user by the electronic apparatus can be made more effective.
Other effects that may be obtained or predicted by the various embodiments of the present disclosure are disclosed explicitly or implicitly in the detailed description of the embodiments of the present disclosure.

A respective one of these communication modules may communicate with external electronic devices via a first network 198 (e.g., a short-range communication network such as bluetooth, wireless fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a conventional cellular network, a 5G network, a next-generation communication network, the internet, or a computer network (e.g., a LAN or wide-area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multiple components (e.g., multiple chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

According to embodiments, a millimeter-wave antenna module may include a printed circuit board, a Radio Frequency Integrated Circuit (RFIC) disposed on a first surface (e.g., a bottom surface) of the printed circuit board or adjacent to the first surface and capable of supporting a specified high frequency band (e.g., a millimeter-wave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., a top surface or a side surface) of the printed circuit board or adjacent to the second surface and capable of transmitting or receiving signals of the specified high frequency band.
At least some of the above components may be interconnected via an inter-peripheral communication scheme (e.g., bus, general Purpose Input Output (GPIO), serial Peripheral Interface (SPI), or Mobile Industrial Processor Interface (MIPI)) and communicatively communicate signals (e.g., commands or data) therebetween.

Fig. 2 is a block diagram of an electronic device, according to various embodiments.
Referring to fig. 2, the electronic device 200 may include a display 220, a touch sensor 230, an illuminance sensor 240, a processor 210, and a memory 250, and some of the illustrated elements may be omitted or replaced in various embodiments.

At least some of the elements of the electronic device 200 shown (or not shown) may be operatively, functionally, and/or electrically connected to one another.
According to various embodiments, the display 220 may display various images according to the control of the processor 210. The display 220 may be implemented as one of a Liquid Crystal Display (LCD), a Light Emitting Diode (LED) display, or an Organic Light Emitting Diode (OLED) display, but is not limited thereto. The display 220 may be configured as a touch screen that detects touch and/or proximity touch (or hover) input using a user body part (e.g., finger) or input device (e.g., stylus). The touch screen may include a touch sensor 230. Display 220 may include at least some elements and/or functions of display module 160 of fig. 1.
According to various embodiments, at least a portion of the display 220 may be flexible and may be implemented as a foldable display or a rollable display.
According to various embodiments, touch sensor 230 may include at least some elements and/or functions of sensor module 176 of fig. 1 and may receive user input on display 220. The touch sensor 230 may be implemented as one of a capacitive touch sensor, a resistive touch sensor, a surface touch sensor, a Projected Capacitive (PCAP) touch sensor, and a Surface Acoustic Wave (SAW) touch sensor, but is not limited thereto. The touch screen of the display 220 of the electronic device 200 may include one or more touch sensors 230.
According to various embodiments, illuminance sensor 240 (e.g., sensor module 176 of fig. 1) may measure illuminance around electronic device 200. The illuminance sensor 240 may be provided in one area where the housing of the electronic device 200 or the display 220 is removed to allow external light to pass through. The illuminance sensor 240 may be implemented as one of a photo sensor, a cadmium sulfide (CDS) sensor, an Ultraviolet (UV) sensor, and an ambient light sensor (AIS), but is not limited thereto.
According to various embodiments, memory 250 may include volatile memory (e.g., volatile memory 132 of FIG. 1) and non-volatile memory (e.g., non-volatile memory 134 of FIG. 1), and may store various data, either temporarily or permanently. Memory 250 may include at least some of the elements and/or functions of memory 130 of fig. 1 and may store program 140 of fig. 1.
According to various embodiments, memory 250 may store various instructions that may be executed by processor 210. These instructions may include control commands such as arithmetic and logical operations, data movement, input/output, etc., that may be recognized by the processor 210.
According to an embodiment, the memory 250 may store luminance data in which luminance values and display luminance values are mapped. The changed brightness data may be stored in the memory 250 by learning default brightness data generated when the electronic device 200 is manufactured and/or brightness change events of the user.
According to various embodiments, processor 210 may be operatively, functionally, and/or electrically connected to each element of electronic device 200, such as display 220, touch sensor 230, illuminance sensor 240, memory 250, etc., and may be an element configured to perform calculations or data processing related to control and/or communication of each element. Processor 210 may include some elements and/or functions of processor 120 of fig. 1.
According to various embodiments, the computing and data processing functions that processor 210 may perform in electronic device 200 are not limited, but various embodiments are described below in which electronic device 200 learns that a user changes brightness. The operations of the processor 210 described below may be performed by loading instructions stored in the memory 250.
According to various embodiments, the processor 210 may select an automatic brightness control mode or a manual brightness control mode based on user input. In the manual brightness control mode, the processor 210 may determine the brightness of the display 220 according to a user's configuration without reference to brightness data stored in the memory 250. In the automatic brightness control mode, the processor 210 may determine the brightness of the display 220 by using the user input and/or brightness data stored in the memory 250. According to an embodiment, the processor 210 may provide a UI for selecting a brightness control mode to the display 220.
According to various embodiments, in the automatic brightness control mode, the processor 210 may configure the brightness of the display 220 with reference to the illuminance information and the brightness data received from the illuminance sensor 240. Luminance values of the display 220 in the luminance values and corresponding luminance values may be mapped to luminance data. The luminance data may be stored in the memory 250. The luminance data may include graphic data, but the data type is not limited. For example, an axis of luminance data (e.g., the x-axis of a row or graphic in a table) may indicate ambient illuminance of the electronic device 200, while another axis (e.g., the y-axis of a column or graphic in a table) may indicate screen luminance of the display 220. The processor 210 may recognize the current ambient illuminance value of the electronic device 200 through the illuminance sensor 240, find a luminance value corresponding to a corresponding illuminance value in the luminance data stored in the memory 250, and configure the screen luminance by using the corresponding luminance value. For example, when the ambient illuminance of the electronic device 200 is the first illuminance, the processor 210 may control the brightness of the display 220 to a first brightness value mapped to the first illuminance value in the brightness data. Thereafter, when the ambient illuminance of the electronic device 200 is changed to the second illuminance, the processor 210 may control the brightness of the display 220 to a second brightness value mapped to the second illuminance value in the brightness data.
According to various embodiments, the processor 210 may change the brightness of the display 220 when a brightness change event is generated based on user input. According to an embodiment, the processor 210 may provide a brightness control UI (user interface) for allowing a user to control the brightness of a screen of the display 220 through the display 220. The brightness control UI may be configured as a bar and may change the brightness of the display 220 from a minimum brightness to a maximum brightness based on user input. For example, the user can change the brightness of the screen to be brighter or darker by touching the brightness control UI and then dragging up and down.
According to various embodiments, when a brightness change event is generated by a user, the processor 210 may generate event information by mapping the current illuminance and brightness of the screen that is changed according to user input. For example, in the luminance data, a value mapped to the first illuminance value is a first luminance value, and a first event in which the user changes the second luminance value through the luminance control UI may be generated. In this case, the processor 210 may generate the first event information by mapping the first illuminance value and the second luminance value.
According to an embodiment, the processor 210 may generate the event information by further mapping information about the time at which the brightness change event is generated by the user to the current illuminance and brightness of the screen changed according to the user input. The time information may include information about a time when the user changes the brightness and/or an accumulated time when the changed brightness is used. For example, when the first event is generated at 2 pm and the second event is generated at 3 pm, the first event information may further include time before the second event is generated, e.g., time information indicating that the electronic device is used for one hour at the second brightness. The processor 210 may store the generated event information in the memory 250. The brightness change event may be accumulated before the brightness data reconfiguration is generated and stored in the memory 250.
According to various embodiments, the processor 210 may generate event information in a section dividing illuminance. For example, the processor 210 may measure the brightness usage time of the user in units of 50 lx. In this case, the processor 210 may calculate illuminance of 100lx to 150lx as one section by the user. The length of each illumination section may be longer or shorter depending on the user configuration. As the length of the illumination section becomes shorter, the electronic device is more sensitive to changes in illumination, and thus can more accurately reflect the brightness setting of the user.
According to various embodiments, the processor 210 may generate temporary brightness data obtained by reconfiguring brightness data stored in the memory 250 based on the acquired event information. The temporary luminance data may be luminance data configured when a luminance change event is generated (e.g., by learning the changed luminance data), wherein luminance values mapped to at least some of the entire luminance section are changed.
According to an embodiment, the processor 210 may immediately reflect the brightness change event in the brightness data to generate temporary brightness data. For example, when a first luminance value is mapped to a first luminance value in luminance data and a user generates a luminance change event for changing the luminance of display 220 to a second luminance, processor 210 may generate temporary luminance data, wherein the second luminance value is mapped to the first luminance value.
According to various embodiments, the processor 210 may control the brightness of the screen of the display 220 according to the generated temporary brightness data. For example, the processor 210 may configure the brightness of the display 220 to be a brightness value that maps to an illuminance value in the temporary brightness data. The processor 210 may additionally modify the temporary luminance data when another luminance value is selected on the luminance control UI according to user input based on the luminance data. The processor 210 may configure the brightness of the display 220 to a brightness value mapped to the current illuminance value with reference to the modified temporary brightness data.
According to various embodiments, when generating temporary luminance data, the processor 210 may also change luminance values mapped to luminances within a reference luminance range in which a luminance change event is generated. The reference range may vary depending on the level of brightness variation. For example, when the user configures a luminance value of 100lx to 300nits, luminance values of 50lx to 150lx may also be changed within 250nits to 350 nits. By also changing the luminance value mapped to the illuminance within the reference range of the illuminance in which the luminance change event is generated, the inversion phenomenon in which the illuminance is reduced but the luminance is increased can be prevented. According to another embodiment, the processor 210 may change the luminance values mapped to luminance values in the entire luminance section.
According to various embodiments, the processor 210 may reconfigure the luminance data when the reset condition is satisfied. The reset condition may include at least one of a condition that the display 220 is not operated for a reset time or more or a condition that the display 220 is operated at illuminance different from an illuminance value detected by the illuminance sensor 240 when the display is last operated. The reset time may be configured by default or may vary depending on user settings, and as the reset time is shorter, the processor 210 may learn the brightness change event more quickly to reconfigure the brightness data. When determining whether the display 220 is operating in a different illumination environment than when the display was last operated, the luminance data cannot be reconfigured within the same illumination section despite the different illumination values. The processor 210 may store event information regarding the brightness change event in the memory 250 before the reset condition is satisfied, and may reconfigure the brightness data with reference to the accumulated event information when the reset condition is satisfied.
According to various embodiments, processor 210 may reflect the accumulated event information to reconfigure the luminance data. The processor 210 may reconfigure the luminance data in consideration of at least one of the luminance, the usage time, and the luminance trend used by the user for each illuminance. The processor 210 may calculate a brightness weight value by using the accumulated event information so as to reconfigure the brightness data. The luminance weight may include at least one of a time weight and a trend weight. The time weighting values may be assigned when a particular (or a particular segment) luminance value is used for a longer period of time in a particular illumination environment. The trend weighting value may be calculated in consideration of the time taken to change the brightness after reconfiguring the brightness data under the corresponding illuminance and the difference between the brightness changed by the user before the reconfiguration and the brightness changed after the reconfiguration. The detailed calculation of the weighting values is described below with reference to fig. 6.
According to an embodiment, the processor 210 may stop measuring the accumulated usage time when there is no touch input by the user for the reference period. Since the screen of the display 220 is not used during the time when there is no user touch input, if the period of time during which the display 220 is turned off is used to calculate the use trend of the brightness, the use trend of the brightness may be distorted. The reference time may be configured at a point in time when the electronic device 200 is manufactured and stored in the memory 250, or may vary depending on user settings.
According to various embodiments, the processor 210 may measure the accumulated usage time when the display 220 is operating and the automatic brightness mode is on. In the automatic brightness mode, the processor 210 may automatically control the brightness of the display 220 according to the brightness data even if the user does not configure the brightness of the display 220. In the manual brightness mode, the processor 210 may configure the brightness of the display 220 based on user input instead of brightness data. For example, the first luminance mapped to luminance data in the first illuminance environment is not configured as the luminance of the display 220, but the second luminance configured by the user may be determined as the luminance of the display 220, and the luminance configured by the user may be maintained regardless of the change in illuminance.
According to various embodiments, the processor 210 may balance processing luminance data to prevent a reverse phenomenon in which a luminance value mapped to a high luminance value becomes lower than a luminance value mapped to a low luminance value when the luminance data is reconfigured. When the luminance data is reconfigured based on the user input, a reverse phenomenon occurs in which the luminance increases when the illuminance becomes lower than an illuminance section in which the luminance is changed by the user or the luminance decreases when the illuminance increases. In order to prevent the inversion phenomenon, when reconfiguring the brightness data, the processor 210 may perform a process of performing the balancing process in consideration of event information. The processor 210 may configure the luminance data to increase the luminance according to the increase of the illuminance by the balancing process, thereby preventing the inversion phenomenon. According to an embodiment, the processor 210 may balance processing luminance data by changing luminance values mapped to luminance sections adjacent to the luminance section where the user changed luminance.
Fig. 3 illustrates a brightness data configuration system of an electronic device, in accordance with various embodiments.
Referring to fig. 3, the electronic device 300 may include a data module 310, a timer 320, a time statistics module 330, a trend (continuity) statistics module 340, a brightness configuration module 350, a reset module 360, and a brightness data reconfiguration module 370. These elements may be interconnected on the tissue for operation, and various elements may be added as well as those shown. The illustrated components (or modules) are software modules and may be operated by a processor (e.g., processor 210 of fig. 2) of electronic device 300.
According to various embodiments, the timer 320 may measure the time that a user maintains a particular brightness while the electronic device 300 is in an active state. The active state may be a state in which a display (e.g., display 220 of fig. 2) is operating and is configured to be in an automatic brightness mode. According to the embodiment, since the state in which the manual brightness mode is configured is not an active state, the use time may not be used. The processor may measure the time of use after switching to the automatic brightness mode based on user input.
According to various embodiments, the timer 320 may receive information from the data module 310 regarding the user's use of the display screen brightness. The timer 320 may measure an accumulated usage time of each brightness based on the received information. For example, the timer 320 may receive information about a user touch input among the information collected by the data module 310. When the touch input is not received for the reference time or longer, the electronic device 300 may be considered not to be used, and the measurement of the use time may be suspended. Thereafter, when the touch input is received again, the user may be considered to start using the electronic device, and the measurement of the use time may be resumed.
According to various embodiments, the processor may collect at least some of the illumination information via the data module 310 and store it in a memory (e.g., memory 250 of fig. 2) along with display brightness attributes identified by an illumination sensor (e.g., illumination sensor 240 of fig. 2) and the cumulative usage time measured by timer 320. The display brightness attribute may include at least one of a brightness trend (continuity) of each illuminance section, a brightness use mode in a night mode, a brightness use mode of each application running in the foreground, a brightness use mode of each color (color temperature), a brightness use mode according to a battery level, and a frequency of a user touch input when a specific application is being used. For example, when a user frequently uses an application including a white UI, the processor may detect how the user configures display screen brightness to use the white UI, generate a brightness usage pattern for each color, and transmit information about the pattern to the data module 310.
According to various embodiments, the processor may send information stored in the data module 310 to elements of the electronic device 300, including at least one of the timer 320, the time statistics module 330, and the trend (continuity) statistics module 340. The calculations performed by at least one element of the electronic device 300 may be performed based on information stored in the data module 310. For example, the time weighted value calculated by the time statistics module 330 may require display brightness levels and information about the time of use in a particular illumination environment. The processor may collect relevant information and communicate the required information to the time statistics module 330 via the data module 310.
According to various embodiments, the time statistics module 330 may collect information about the accumulated usage time for each illuminance and calculate a time weighting value. The time weighting value may be determined in proportion to the time when the user actually uses the corresponding brightness. For example, as the user uses a particular brightness for a longer period of time, a higher weighting value may be assigned. For example, when the user uses 100nits for 1 hour and 200nits for 2 hours under the first illuminance, a time weight value of 100nits may be calculated as 1, and a time weight value of 200nits may be calculated as 2.
According to various embodiments, the time statistics module 330 may receive brightness change event information and information regarding a brightness usage pattern of a user from the data module 310 and the timer 320. The time statistics module 330 may receive information about the accumulated usage time of each illuminance measured by the timer 320 and calculate a time weighting value based on the information.
According to various embodiments, the continuity statistics module 340 may collect information about the brightness usage patterns of the users and calculate the continuity weight values. The continuity weight value may be a value obtained by analyzing a brightness usage pattern of the user under a specific illuminance. For example, a user's preference for higher brightness of a display screen in a low-light environment may be reflected in the calculation of a continuity weight value, and thus a higher continuity weight value may be assigned to maintain higher screen brightness in a lower-light environment.
According to various embodiments, the processor may calculate the luminance weight according to [ equation 1] below.
[ formula 1]
W n ＝f(T n ，C n )＝T n +C n
W n : luminance weighting value
T n : time weighting value
C n : continuity weight value
According to various embodiments, the time weighting value (T n ) And a continuity weight value (C n ) And the brightness weight value is calculated in addition. For example, when the usage time is 10 hours and the event continuity value is 30, the luminance weight value may be calculated as 40. The luminance weight value may determine an importance degree of a corresponding luminance value reflected in the reconfiguration of the luminance data.
[ formula 2]
According to various embodiments, the processor may reconfigure the luminance data according to [ equation 2] above. B1, B2, etc. are different brightnesses for a particular illuminance, and W1, W2, etc. are corresponding brightness weighting values. Information about the brightness change event may be stored in a memory (e.g., memory 250 of fig. 2), and the processor may use the information to calculate brightness weight values and reconfigure the brightness data.
According to various embodiments, the time statistics module 330 and the continuity statistics module 340 may send the collected information about the accumulated usage time of each illuminance, the user brightness usage pattern, and the calculated brightness weighting value to the brightness configuration module 350.
According to various embodiments, when a user changes brightness to a value different from a value mapped to brightness data under a specific illuminance, the processor may generate temporary brightness data in the brightness configuration module 350. The luminance configuration module 350 may generate temporary luminance data based on the event information and the luminance weight values received from the time statistics module 330 and the continuity statistics module 340. The processor may change the display brightness according to the temporary brightness data generated by the brightness configuration module 350 before reconfiguring the brightness data due to the satisfaction of the reset condition. For example, the processor may receive information about a current luminance value from a luminance sensor (e.g., luminance sensor 240 of fig. 2) and determine a luminance value mapped to a corresponding luminance value in the temporary luminance data generated by luminance configuration module 350 as the display screen luminance. The luminance configuration module 350 may change the temporary luminance data every time user input is received. Since a plurality of user inputs may be received even before the luminance data is reconfigured, the temporary luminance data may be continuously changed. According to an embodiment, when generating temporary luminance data, the luminance configuration module 350 may further change the luminance mapped to the luminance section adjacent to the luminance section whose luminance is changed by the user input.
According to various embodiments, the reset module 360 may determine whether the reset condition is met. The reset module 360 may receive at least one piece of information about illuminance around the electronic device 300 and information indicating whether the display is operated from the data module 310. When the reset condition is satisfied, the reset module 360 may determine that the reset condition is satisfied, and the luminance data reconfiguration module 370 may support the reset of the luminance data.
According to various embodiments, when the luminance configuration module 350 reflects the temporary luminance data, the time weight value, and the continuity weight value, the luminance data reconfiguration module 370 may reconfigure the luminance data in consideration of all event information. According to an embodiment, when the luminance data is reconfigured, the luminance data reconfiguration module 370 may further change the luminance mapped to the luminance section adjacent to the luminance section whose luminance is changed by the user input. When the reset module 360 determines that the reset condition is satisfied, the luminance data reconfiguration module 370 may reconfigure the luminance data. The luminance data reconfiguration module 370 may initialize temporary luminance data when reconfiguring luminance data.
According to various embodiments, luminance data reconfiguration module 370 may process the balancing while reconfiguring the luminance data. When the brightness is changed only in the illuminance section where the brightness change event is generated, the inversion phenomenon may occur, and thus the brightness data reconfiguration module 370 may process the balance so as to prevent the inversion phenomenon. For example, luminance values mapped to luminance segments adjacent to the luminance segment that generated the luminance change event.
Fig. 4 illustrates a weighted value scenario based on accumulated usage time of an electronic device, in accordance with various embodiments.
According to an embodiment, fig. 4 shows brightness in a graph form by way of example for convenience of description, but the brightness data is not limited thereto. For example, the luminance data may include tabular data, and the visualized tabular data may have a form shown in fig. 4.
Referring to fig. 4, a processor (e.g., processor 210 of fig. 2) may reconfigure luminance data based on a user's luminance aggregate usage time. The luminance data stored in the memory (e.g., memory 250 of fig. 2) may be configured as shown in diagram 410. According to an embodiment, default brightness data 411 may be stored in memory at the time of electronic device manufacture. The luminance also increases as the illuminance increases, and the processor may obtain illuminance information from an illuminance sensor (e.g., illuminance sensor 240 of fig. 2) and determine the luminance of a display (e.g., display 220 of fig. 2) as a luminance value in the luminance data that maps to an illuminance value around the electronic device.
According to various embodiments, the processor may change the display brightness based on user input. The luminance data and temporary luminance data 421 generated by the user input may be configured as shown in the graph 420. When the user is at illumination x 1 423 from y 1 Change to y 2 In this case, the processor may generate temporary luminance data 421 reflecting the corresponding user input. The processor may change the illuminance x mapped to the input user touch by more than just changing 1 And changing the luminance values mapped to adjacent luminance segments to process the balancing. Since the reset condition is satisfied, before the luminance data is reconfiguredThe processor may determine the display brightness as a brightness value mapped to the generated temporary brightness data 421. For example, after generating the brightness change event, the processor may determine that the brightness is x 1 423 with a display brightness y in the environment 2 。
According to various embodiments, the processor may reconfigure the luminance data when the reset condition is satisfied. The processor may reconfigure the luminance data in consideration of at least one of a luminance integrated use time of the user and a difference between the luminance changed before the reconfiguration and the luminance changed after the reconfiguration. Graph 430 shows luminance data 411 and temporary luminance data 421 before reconfiguration, and luminance data 431 after reconfiguration. The reconfigured luminance data 431 may be configured to be closer to the temporary luminance data 421 from the luminance data 411 before the reconfiguration.
For example, a first event in which the display luminance configured as 200nits in an environment where the illuminance is 300lx in the luminance data 411 is changed to 250nits and the electronic apparatus is used for 1 hour may be generated. Thereafter, in the luminance data 431 reconfigured when the reset condition is satisfied, in an environment where the illuminance is 300lx, the display luminance may be determined between 200nits and 250 nits.
According to various embodiments, the processor may calculate a temporal weighting value and a continuity weighting value and reconfigure the luminance data based on them. Graph 440 shows reconfigured luminance data 441 when the time of use is different from the user-changed luminance. The processor may reconfigure the luminance data taking into account the time of use at the corresponding luminance. For example, when the use time at a specific luminance value is longer, the luminance data may be reconfigured to have a higher weighting value. For example, when the first event is generated as 5 hours, the processor may reconfigure the luminance data to be closer to the temporary luminance data 421 than shown in graph 430.
For example, a first event may be generated in which a user uses an electronic device at a luminance of 180nits mapped to luminance data for 1 hour at 500lx luminance, moves to 0lx luminance and uses the electronic device at a luminance of 10nits mapped to luminance data for 0.1 hour, changes display luminance to 100nits at the same luminance and uses the electronic device for 1 hour, and the user may move to 500lx luminance and uses the electronic device at a luminance of 180nits mapped to luminance data for 2 hours. Thereafter, when the reset condition is satisfied, the processor may learn the sections of 0lx and 500 lx. This can be shown in the table below.
TABLE 1
/>
[ formula 3]
When the continuity weight value is assumed to be 0, only one luminance (180 nits) is used in a section of 500lx, and thus luminance learning may not be performed, and the luminance weight value calculated in a section of 0lx may be a time weight value, and calculated as shown in [ formula 3 ]. In reconfiguring the luminance data, the processor may configure the luminance in 0lx to 91.9 instead of 10. The processor may also control the luminance value of the illuminance to be higher than or equal to 0lx to prevent the inversion phenomenon. For example, the processor may control all luminance values mapped to luminance segments greater than or equal to 0lx to be greater than or equal to 91.9nits.
Fig. 5 illustrates a brightness configuration continuity weight scenario of an electronic device, in accordance with various embodiments.
According to an embodiment, fig. 5 shows brightness in a graph form by way of example for convenience of description, but the brightness data is not limited thereto. For example, the luminance data may include tabular data, and the visualized tabular data may have a form shown in fig. 5.
Referring to fig. 5, a processor (e.g., processor 210 of fig. 2) may reconfigure luminance data based on a user's luminance configuration continuity. The luminance data stored in the memory (e.g., memory 250 of fig. 2) may be configured as shown in fig. 510. According to an embodiment, default brightness data 511 may be stored in memory at the time of electronic device manufacture. The luminance also increases as the illuminance increases, and the processor may obtain illuminance information from an illuminance sensor (e.g., illuminance sensor 240 of fig. 2) and determine the luminance of a display (e.g., display 220 of fig. 2) as a luminance value that maps to an illuminance value around the electronic device in luminance data 511.
According to various embodiments, the processor may change the display brightness based on user input. The luminance data and temporary luminance data 521 generated by the user input may be configured as shown in the graph 520. When the user is at illumination x 2 523 and x 3 When the brightness is changed in the environment of 525, the processor may generate temporary brightness data 521 reflecting the corresponding user input. The processor may also change the mapping to x, the luminance value 2 523 and x 3 The luminance values of adjacent illumination segments of segments 525 to prevent the inversion phenomenon.
According to various embodiments, the processor may reconfigure the luminance data when the reset condition is satisfied. Graph 530 shows luminance data 511 and temporary luminance data 521 before reconfiguration, and luminance data 531 after reconfiguration. The reconfigured luminance data 531 may be located between the luminance data 511 and the temporary luminance data 521 before the reconfiguration. The processor may configure the luminance data differently in view of the continuity weight value. Since the user uses the electronic device at the changed brightness more frequently than the brightness value mapped to the conventional brightness data 511, the brightness data may be reconfigured to be closer to the temporary brightness data 521. For example, when a user tends to use higher luminance than the value mapped to luminance data more frequently in a lower luminance environment and lower luminance than the value mapped to luminance data more frequently in a higher luminance environment, the processor may, when reconfiguring the luminance data, determine that the luminance data is not available 2 Higher luminance values are mapped in the section comprising the illuminanceValue x 3 Lower luminance values are mapped in the segments of (a). According to an embodiment, the processor may track the usage pattern of the user and continuously calculate and reflect the continuity weight value. For example, if the user uses higher luminance more frequently at lower illuminance and the tendency to use lower luminance at higher illuminance increases, the luminance may be reconfigured closer to the temporary luminance data 521 as shown in the graph 540 than the luminance data 511 before reconfiguration.
According to various embodiments, when reconfiguring luminance data, the processor may process the balancing by also changing luminance values mapped to luminance sections adjacent to the luminance section where the user changed luminance.
For example, a first event may be generated in which a user uses an electronic device at a luminance of 91.9nits mapped to luminance data for 50 hours at 0lx illuminance, and changes display luminance to 180nits at the same illuminance and uses the electronic device for one hour. Thereafter, when the reset condition is satisfied, the processor may process learning of the 0lx section. Thereafter, a second event may be generated that changes the display luminance from 93.6nits to 180nits at the same illuminance, and the reset condition is satisfied, so the processor may process the learning of the 0lx section again. This can be shown in the table below.
TABLE 2
[ equation 4]
B 1 ＝91.9nit,W 1 ＝50(T 1 ＝50,C 1 ＝0)
[ equation 5]
B 2 ＝180nit,W 2 ＝1(T 2 ＝1，C 2 ＝0)
[ formula 6]
[ formula 4]]To [ formula 6]]Is the first learning process in the 0lx section. The processor may use the brightness data of the event information reconfigured as a brightness change event for 1 month. When the user uses the electronic device at 91.9nits for 50 hours at 01x, changes 91.9nits to 180nits and uses for 1 hour, and then reconfigures the luminance data, when it is assumed that there is no continuity weight (C 1 ，C 2 ) When, above [ formula 6]]May be true. The reconfigured luminance data may map an illuminance of 0lx and a luminance of 93.6nits. Thereafter, the processor may determine the display brightness to be 93.6nits in a 01x illuminance environment.
[ formula 7]
B 1 ＝93.6nit,W 1 ＝51(T 1 ＝51，C 1 ＝0)
[ formula 8]
B 2 ＝180nit，W 2 ＝101(T 2 ＝1，C 2 ＝100)
[ formula 9]
[ formula 7]]To [ formula 9]]Is the second learning process in the 01x section. The processor may store the previously reconfigured luminance data in memory and use the data. When the user changes the brightness to 180nits at 01x and uses the electronic device for 1 hour, and then the reset condition is satisfied and thus the brightness data is reconfigured, the processor may perform the above [ formula 9]]The calculation shown. In [ formula 8]]In the second event, a continuity weight value such as C 2 Is configured as 100, wherein the user changes the brightness from, for example, 93.6nits to 180nits, the continuity weight value may be calculated taking into account at least one of the brightness changed by the user before the reconfiguration and the difference between the brightness data reconfiguration and the brightness change after the reconfiguration. Thereafter, the process The display luminance may be determined to be 151nits in an environment of 0 lx.
Fig. 6 illustrates a scenario in which the usage time of each luminance of the continuity weight value of the electronic device is calculated according to various embodiments.
According to various embodiments, a processor (e.g., processor 210 of fig. 2) may calculate a continuity weight value for reconfiguring luminance data. The processor may calculate the continuity weight value in consideration of at least one of a brightness configuration of a user, a use time, a brightness configuration according to a battery level, a brightness configuration according to an application running in the foreground or the background, a brightness configuration according to a color of each UI, and a brightness configuration when the night mode is running, or one of a combination of two or more thereof, but the present disclosure is not limited thereto.
According to various embodiments, when calculating the continuity weight value in consideration of the luminance configuration, the processor may calculate the continuity weight value in consideration of a difference between the luminance changed before the reconfiguration and the luminance changed after the reconfiguration and/or a time taken until the user changes the luminance again after the luminance data reconfiguration. Fig. 6 shows a case 600 where luminance data is reconfigured by a user after a luminance change. When the ambient illuminance of the electronic device is the first illuminance, the processor may configure the brightness of the display (e.g., display 200 of fig. 2) to B according to the value mapped to the first brightness data 0 . Thereafter, when the user changes the brightness to B 1 The processor may generate temporary luminance data and change the luminance value in the first illuminance to B 1 . Subsequently, when at T 1 When the reset condition is satisfied, the luminance data may be reconfigured. When the luminance data is reconfigured, the user has already moved the luminance from B 0 Change to B 1 And is therefore higher than the value B 0 Is the value of the first luminance mapped into the luminance data before reconfiguration. When the user is at T 2 Changing the brightness to B again 2 And at T 3 When the luminance data is reconfigured, the reconfigured luminance data may be configured such that the value mapped to the first illuminance is closer to B 1 Instead of B 0 。
According to various embodiments, the processor may take into account the brightness (B) that the user changes before the brightness data is reconfigured 1 ) And brightness changed by the user after reconfiguration (B 2 ) The difference between them to calculate the continuity weight. When B is 1 And B 2 When the difference between them is smaller, it is determined that the user is more likely to use the corresponding brightness, and a higher continuity weight value may be assigned. On the other hand, when B 1 And B 2 When the difference between them is large, it is determined that the user is not likely to use the corresponding luminance, and a lower continuity weight value may be assigned. According to an embodiment, when B 1 And B 2 Difference between (B) threshold ) Greater than or equal to a predetermined value, the processor may calculate the continuity weight value as 0.
According to various embodiments, the processor may consider a point in time (T1 ) And a time point (T 2 ) The time between them to calculate the continuity weight. When T is 1 And T 2 The interval between is shorter, it is determined that the user is more likely to prefer the corresponding brightness, and a higher continuity weight value may be assigned. On the other hand, when T 1 And T 2 With longer intervals in between, it is determined that the user is unlikely to use the corresponding brightness, and a lower continuity weight value may be assigned. According to an embodiment, when T 1 And T 2 Interval between (T) threshold ) Greater than or equal to a predetermined value, the processor may calculate the continuity weight value as 0.
An electronic device (e.g., electronic device 101, electronic device 200, or electronic device 300) according to various embodiments includes a display (e.g., display module 160 or display 220), a touch sensor (e.g., touch sensor 230) configured to receive a touch input from a user and generate touch information, an illuminance sensor (e.g., illuminance sensor 240) configured to detect ambient illuminance and generate illuminance information, a memory (e.g., memory 130 or memory 250) configured to store luminance data of a relationship between ambient illuminance and luminance of the display, and a processor (e.g., processor 120 or processor 210) operatively connected to the display, illuminance sensor, touch sensor, and memory, wherein the processor may be configured to identify illuminance information from the illuminance sensor, configure the luminance of the display to a first luminance, change the luminance of the display to a second luminance based on the user input, obtain event information for an operation of changing the luminance of the display, reconfigure the luminance data stored in the memory based on the event information, and determine a display luminance value from the mapped value identified by the illuminance sensor in the reconfigured data.
According to various embodiments, the processor may be configured to generate temporary luminance data based on the changed luminance when the luminance of the display is changed to the second luminance based on the user input, and determine the luminance of the display from luminance values mapped to the illuminance information in the temporary luminance data before the luminance data is reconfigured.
According to various embodiments, the processor may be configured to, when generating the temporary luminance data, also change a luminance value mapped to an illuminance within a reference range of the illuminance in which the luminance is changed.
According to various embodiments, the processor may be configured to calculate a time weight value and a continuity weight value based on the event information, and further to reconfigure the luminance data using the calculated time weight value and continuity weight value.
According to various embodiments, the processor may be configured to calculate the continuity weight value taking into account the time taken until the brightness changes again after the brightness data is reconfigured and the difference between the brightness changed by the user before the reconfiguration and the brightness changed after the reconfiguration.
According to various embodiments, the processor may be configured to reconfigure the luminance data when at least one of a time when the display is not operated longer than a predetermined reset time and a case when the display is operated at an illuminance different from an illuminance value detected by the illuminance sensor when the display is last operated is satisfied.
According to various embodiments, the processor may be configured to, when reconfiguring the luminance data, also change the luminance value mapped to luminances within a reference range of luminances in which the luminance is changed.
According to various embodiments, the processor may be configured to identify touch information from the touch sensor and exclude a corresponding time from the calculation of the accumulated usage time based on the touch information when no touch input is received for longer than or equal to the reference time.
According to various embodiments, the illuminance sensor may be configured to measure illuminance in a section divided at a predetermined interval.
According to various embodiments, the processor may be configured to generate event information when the display is operated based on user input and the automatic brightness mode is configured.
Fig. 7 is a flowchart illustrating an automatic brightness learning method of an electronic device according to various embodiments.
The illustrated method may be performed by at least one element (e.g., the processor 120 of fig. 1 or the processor 210 of fig. 2) included in an electronic device (e.g., the electronic device 101 of fig. 1, the electronic device 200 of fig. 2, or the electronic device 300 of fig. 3), and the description of the technical features that have been described above may be omitted hereinafter.
According to various embodiments, in operation 710, the electronic device may configure the brightness of a display (e.g., display 220 of fig. 2) with reference to the illuminance information and the brightness data identified by the illuminance sensor (e.g., illuminance sensor 240 of fig. 2). The luminance value and the display luminance value of the corresponding luminance values may be mapped in the luminance data. For example, when the luminance data has a chart form, the x-axis of the chart may indicate the ambient illuminance of the electronic device and the y-axis may indicate the display screen luminance. The electronic device may receive information from the illuminance sensor indicating a current ambient illuminance value of the electronic device, find a luminance value corresponding to the corresponding illuminance value in luminance data stored in a memory (e.g., memory 250 of fig. 2), and configure the luminance value as the corresponding luminance value. For example, when the ambient illuminance of the electronic device is the first illuminance, the electronic device may control the display luminance to a first luminance value mapped to the first illuminance value in the luminance data. Thereafter, when the ambient illuminance of the electronic device is changed to the second illuminance, the electronic device may control the display luminance to a second luminance value mapped to the second illuminance value in the luminance data.
According to various embodiments, in operation 711, the electronic device may receive an input for use by a user to change brightness. The processor may control the display brightness in accordance with user input.
According to various embodiments, when the brightness change event is generated based on the user input, the electronic device may change the display brightness in operation 720. According to an embodiment, the electronic device may provide a brightness control UI for allowing a user to control the brightness of the display screen. The brightness control UI may be configured as a bar and may change the brightness of the display from a minimum brightness to a maximum brightness based on user input. For example, the user can change the brightness of the screen to be brighter or darker by touching the brightness control UI and then dragging up and down.
According to various embodiments, in operation 730, the electronic device may map the illuminance of the brightness change event generated by the user and the changed screen brightness to generate event information. For example, in the luminance data, a value mapped to the first illuminance value is a first luminance value, and a first event in which the second luminance value is changed by the user through the luminance control UI may be generated. In this case, the electronic device may map the first illuminance value and the second luminance value to generate the first event information. According to an embodiment, the electronic device may also map information about the time of the brightness change event generated by the user to generate event information. The time information may include information about a time when the user changes the brightness and/or an accumulated time when the changed brightness is used. The electronic device may store the generated event information in a memory. The brightness change event may be accumulated before the brightness data reconfiguration (graphics reconfiguration) is generated and stored in memory.
According to various embodiments, the electronic device may generate event information for each illumination segment. The length of each illumination section may be longer or shorter depending on the user configuration. When the length of the illumination section is shorter, the electronic device is more sensitive to illumination change, and can reflect the brightness setting of the user more accurately.
According to various embodiments, in operation 740, the electronic device may generate temporary brightness data obtained by reconfiguring brightness data stored in the memory based on the acquired event information. The electronic device may immediately reflect the brightness change event in the brightness data to generate temporary brightness data. The electronic device may control the display screen brightness according to the generated temporary brightness data. For example, the display luminance may be configured as a luminance value that maps to an illuminance value in the temporary luminance data. The electronic device may continuously modify the temporary luminance data according to the user input based on the luminance data. The electronic device may configure the display luminance to a luminance value mapped to the current luminance value with reference to the modified temporary luminance data.
According to various embodiments, when generating temporary luminance data, the electronic device may also change luminance values mapped to luminances within a reference luminance range in which a luminance change event is generated. The reference range may vary depending on the level of brightness change. By also changing the luminance value mapped to the illuminance within the reference range of the illuminance in which the luminance change event is generated, the inversion phenomenon in which the illuminance is reduced but the luminance is increased can be prevented.
According to various embodiments, in operation 750, the electronic device may determine whether a reset condition is satisfied. When the reset condition is satisfied ("yes" of operation 750), the electronic device may reconfigure the luminance data. The reset condition may include at least one of the display not being operated for a reset time or more and the display being operated at an illuminance different from an illuminance value detected by the illuminance sensor when the display was last operated. The reset time may vary depending on user settings, and when the reset time is shorter, the electronic device may quickly learn the brightness change event to reconfigure the brightness data. When determining whether the display is operating in a different illumination environment than in the previous operation, if the illumination values are different but the illumination sections are the same, a reconfiguration of the data may not be generated. The electronic device may store event information of the brightness change event in the memory before the reset condition is satisfied (e.g., no of operation 750), and may reconfigure the brightness data with reference to the accumulated event information when the reset condition is satisfied.
According to various embodiments, in operation 760, the electronic device may reflect the accumulated event information to reconfigure the brightness data. The electronic device may reconfigure the luminance data in consideration of at least one of the luminance, the use time, and the luminance continuity used by the user for each illuminance. The electronic device may calculate the brightness weight value by using the accumulated event information in order to reconfigure the brightness data. The luminance weight may include at least one of a time weight and a trend weight. The time weighted value may be assigned when a particular luminance value is used for a longer period of time in a particular illumination environment. The continuity weight value may be calculated in consideration of time taken to change the brightness after reconfiguring the brightness data at the corresponding illuminance and a difference between the brightness changed by the user before the reconfiguration and the brightness changed after the reconfiguration.
According to various embodiments, the electronic device may suspend the measurement of the accumulated usage time when there is no touch input by the user for the reference time. Since it appears that the display screen is not used during the time when there is no user touch input, the continuity of brightness use may be distorted when reflecting the corresponding time. The reference time may vary depending on user settings.
According to various embodiments, the electronic device may measure the accumulated usage time when the display is operating and the automatic brightness mode is on. The electronic device may automatically control the display luminance according to the luminance data in the automatic luminance mode even if the user does not configure the display luminance. In the manual brightness mode, the electronic device may configure the display brightness based on user input instead of brightness data.
According to various embodiments, the electronic device may handle balancing when the luminance data is reconfigured. When the luminance data is reconfigured based on the user input, a reverse phenomenon occurs in which the luminance increases when the illuminance becomes lower than an illuminance section in which the luminance is changed by the user or the luminance decreases when the illuminance increases. When reconfiguring the luminance data, the electronic device may perform the balancing process in consideration of the event information so as to prevent the inversion phenomenon. When the luminance data is configured to increase luminance as illuminance increases, the inversion phenomenon can be prevented. According to an embodiment, the electronic device may process the balancing by also changing the luminance value mapped to the luminance segment adjacent to the luminance segment where the user changed the luminance.
The electronic device may include at least one of a data module, a timer, a time statistics module, a continuity statistics module, a brightness configuration module, a reset module, and a brightness data reconfiguration module, and these elements may be organically connected to each other to operate.
According to various embodiments, the timer may measure the time that a user maintains a particular brightness while the electronic device is in an active state. The active state may be a state in which the display is operating and is configured to an automatic brightness mode. According to the embodiment, since the state in which the manual brightness mode is configured is not an active state, the use time may not be used. The electronic device may measure the time of use after switching to the automatic brightness mode based on user input.
According to various embodiments, the timer may receive information from the data module regarding the brightness of the display screen used by the user. The timer may measure an accumulated usage time for each brightness based on the received information. For example, the timer may receive information about a user touch input from among the information collected by the data module. When the touch input is not received for the reference time or longer, the electronic device may be considered not to be used, and the measurement of the use time may be suspended. Thereafter, when the touch input is received again, the user may be considered to start using the electronic device again, and the measurement of the use time may be resumed.
According to various embodiments, the electronic device may collect and store at least one of illuminance information and display brightness attribute received from the illuminance sensor and an accumulated use time measured by the timer through the data module. The display brightness attribute may include at least one of a brightness continuity of each illuminance section, a brightness usage pattern in a night mode, a brightness usage pattern of each application running in the foreground, a brightness usage pattern of each color (color temperature), a brightness usage pattern according to a battery level, and a frequency of a user touch input when a specific application is being used. For example, when a user frequently uses an application including a white UI, the electronic device may detect how the user configures display screen brightness when using the white UI, so as to generate a brightness usage pattern for each color, and transmit information about the pattern to the data module.
According to various embodiments, the electronic device may send information stored in the data module to each element of the electronic device, including at least one of a timer, a time statistics module, and a continuity statistics module. The elements of the electronic device are organically connected to each other, and the computation performed by each module may be performed based on information stored in the data module. For example, the time weighting value calculated by the time statistics module may require information about the level of display brightness and the time of use in a particular illumination environment. The electronic device may collect the relevant information and send the required information to the time statistics module via the data module.
According to various embodiments, the time statistics module may calculate the time weighting value by collecting information about the accumulated time of use for each illuminance. The time weighting value may be determined in proportion to the time when the user uses the corresponding brightness. For example, when a specific luminance is used for a longer time, the assigned weighting value is higher.
According to various embodiments, the time statistics module may receive brightness change event information and information regarding a brightness usage pattern of a user from the data module and the timer. The time statistics module may receive information about the accumulated usage time of each illuminance measured by the timer and calculate a time weighting value based on the information.
According to various embodiments, the continuity statistics module may calculate the continuity weight value by collecting information about the brightness usage pattern of the user. The continuity weight value may be a value obtained by analyzing a brightness usage pattern of the user under a specific illuminance. For example, by reflecting the user's preference for higher display screen brightness in a lower illumination environment in the calculation of the continuity weight value, a higher continuity weight value may be assigned to maintain a higher screen brightness even in a lower illumination environment.
According to various embodiments, the electronic device may determine the time weighting value (T n ) And a continuity weight value (C n ) And the brightness weight value is calculated in addition. For example, when the usage time is 10 hours and the event continuity value is 30, the luminance weight value may be calculated as 40. The luminance weight value may determine an importance degree of a corresponding luminance value reflected in the reconfiguration of the luminance data.
According to various embodiments, the electronic device may reconfigure the luminance data. Information about the brightness change event may be stored in memory for each section, and the electronic device may calculate brightness weight values and reconfigure the brightness data by using the information.
According to various embodiments, the time statistics module and the continuity statistics module may send collected information about the accumulated usage time of each illuminance, the user brightness usage pattern, and the calculated brightness weighting value to the brightness configuration module.
According to various embodiments, when a user changes brightness to a value different from a value mapped to brightness data under a specific illuminance, the electronic device may generate temporary brightness data in the brightness configuration module. The luminance configuration module may generate temporary luminance data based on the luminance weight and event information received from the time statistics module and the continuity statistics module. The electronic device may change the display brightness according to the temporary brightness data generated by the brightness configuration module before the brightness data is reconfigured due to the satisfaction of the reset condition. For example, information about a current illuminance value may be received from an illuminance sensor, and a luminance value mapped to a corresponding illuminance value in temporary luminance data generated by a luminance configuration module may be determined as the luminance of the display screen. The luminance configuration module may change the temporary luminance data each time a user input is received. Since a plurality of user inputs may be received even before the luminance data is reset, the temporary luminance data may be continuously changed. According to an embodiment, when the temporary luminance data is generated, the luminance configuration module may further change the luminance mapped to the luminance section adjacent to the luminance section whose luminance is changed by the user input.
According to various embodiments, the reset module may determine whether the reset condition is met. The reset module may receive information regarding at least one of illuminance information around the electronic device and whether the display is operating from the data module. When the reset condition is satisfied, the reset module may determine that the reset condition is satisfied, and the luminance data reconfiguration module may support the reconfiguration of the luminance data.
According to various embodiments, the luminance data reconfiguration module may reconfigure the luminance data in consideration of all event information reflected in the temporary luminance data, the time weighting value, and the continuity weighting value by the luminance configuration module. According to an embodiment, when the luminance data is reconfigured, the luminance data reconfiguration module may further change the luminance mapped to the luminance section adjacent to the luminance section whose luminance is changed by the user input. The luminance data reconfiguration module may reconfigure the luminance data when the reset module determines that the reset condition is satisfied. The luminance data reconfiguration module may initialize temporary luminance data when the luminance data is reconfigured.
According to various embodiments, the luminance data reconfiguration module may process the balancing while reconfiguring the luminance data. When the brightness is changed only in the illuminance section where the brightness change event is generated, the inversion phenomenon may occur, and thus the brightness data reconfiguration module may process the balance so as to prevent the inversion phenomenon. For example, the luminance values mapped to luminance segments adjacent to the luminance segment that generated the luminance change event may also be changed.
The electronic device may reconfigure the brightness data based on the accumulated usage time of brightness by the user. According to an embodiment, default brightness data may be stored in memory at the time of manufacture of the electronic device. The luminance increases as the illuminance increases, and the electronic device may acquire illuminance information from the illuminance sensor and determine the display luminance as a luminance value that is mapped to an illuminance value around the electronic device in the luminance data.
According to various embodiments, the electronic device may change the display brightness based on user input. When a user changes brightness, the electronic device may generate temporary brightness data reflecting the corresponding user input. The electronic device may process the balancing by changing not only the brightness mapped to the illuminance of the input user touch, but also the brightness values mapped to adjacent illuminance segments. The electronic device may determine the display brightness as a brightness value mapped to the generated temporary brightness data before the brightness data is reconfigured due to the satisfaction of the reset condition. For example, after generating the brightness change event, the electronic device may determine the display brightness as a change value in the same illumination environment.
According to various embodiments, the electronic device may reconfigure the luminance data when the reset condition is satisfied. The electronic device may reconfigure the luminance data in consideration of at least one of a cumulative use time of the luminance by the user and a difference between the luminance changed before the reconfiguration and the luminance changed after the reconfiguration. The reconfiguration luminance data may be configured to be closer to temporary luminance data from luminance data prior to the reconfiguration.
According to various embodiments, the electronic device may calculate a time weight and a continuity weight and reconfigure the luminance data based on them. The electronic device may reconfigure the luminance data in consideration of the usage time of the corresponding luminance. For example, when the use time at a specific luminance value is longer, the luminance data may be reconfigured to have a higher weighting value.
The electronic device may reconfigure the brightness data based on the user's brightness configuration continuity. According to an embodiment, default brightness data may be stored in memory at the time of manufacture of the electronic device. The luminance increases as the illuminance increases, and the electronic device may acquire illuminance information from the illuminance sensor and determine the display luminance as a luminance value that is mapped to an illuminance value around the electronic device in the luminance data.
According to various embodiments, the electronic device may change the display brightness based on user input. When a user changes brightness, the electronic device may generate temporary brightness data reflecting the corresponding user input. The electronic device may also change the luminance value mapped to the illumination section adjacent to the illumination section where the user changes the luminance in order to prevent the inversion phenomenon.
According to various embodiments, the electronic device may reconfigure the luminance data when the reset condition is satisfied. The reconfigured luminance data may be located between the luminance data before the reconfiguration and the temporary luminance data. The electronic device may configure the shape of the chart differently in view of the continuity weight. Since the user is more likely to use the changed luminance than the luminance value mapped to the existing luminance data, the luminance data may be reconfigured to be closer to the temporary luminance data. For example, when a user is more likely to use higher luminance than the value mapped to luminance data in a lower luminance environment and is more likely to use lower luminance than the value mapped to luminance data in a higher luminance environment, the electronic device may map higher luminance values to lower luminance sections and lower luminance values to higher luminance sections when reconfiguring the luminance data. According to an embodiment, the electronic device may continuously calculate and reflect the continuity weight value by tracking the usage pattern of the user.
According to various embodiments, when reconfiguring luminance data, the electronic device may process the balancing by also changing luminance values mapped to luminance sections adjacent to the luminance section where the user changed luminance.
According to various embodiments, the electronic device may calculate the continuity weight value by reconfiguring the luminance data. The electronic device may calculate the continuity weight value in consideration of at least one of a brightness configuration of a user, a use time, a brightness configuration according to a battery level, a brightness configuration according to an application running in the foreground or the background, a brightness configuration according to a color of each UI, and a brightness configuration when the night mode is running, or one of a combination of two or more thereof, but is not limited to the above-described example.
According to various embodiments, when calculating the continuity weight value in consideration of the configuration of the brightness, the electronic device may calculate the continuity weight value in consideration of a difference between the brightness changed before the reconfiguration and the brightness changed after the reconfiguration and/or a time taken until the user changes the brightness again. When the ambient illuminance of the electronic device is the first illuminance, the electronic device may configure the display luminance to a value mapped to the first luminance data. Thereafter, when the user changes the brightness, the electronic apparatus may generate temporary brightness data and configure the temporary brightness data to a value to which the brightness value is changed under the first illuminance. Thereafter, the reset condition is satisfied, and thus the luminance data can be reconfigured. When the luminance data is reconfigured, the user changes the luminance, and thus a value larger than the value mapped to the first illuminance in the luminance data before the reconfiguration can be mapped. When the user changes the brightness again and the brightness data is reconfigured, in the reconfigured brightness data, the value mapped to the first illuminance may be configured to be a higher value than the value mapped to the initial brightness data.
According to various embodiments, the electronic device may calculate the continuity weight value in consideration of a difference between a brightness that a user changes before the reconfiguration of the brightness data and a brightness that a user changes after the reconfiguration. It can be determined that when the difference between two brightnesses is smaller, the user is more likely to use the corresponding brightness, and thus a higher continuity weight value can be assigned. On the other hand, it can be determined that when the difference between the two brightnesses is larger, the user is less likely to use the corresponding brightness, and thus a lower continuity weight value can be assigned. According to an embodiment, the electronic device may calculate the continuity weight value as 0 when the difference between the two brightnesses is greater than or equal to a predetermined value.
According to various embodiments, the electronic device may calculate the continuity weight value considering an interval between a point in time when the luminance data is reconfigured and a point in time when a luminance change event of the user is generated after the reconfiguration. It can be determined that when the interval between two time points is shorter, the user is more likely to prefer the corresponding brightness, and thus a higher continuity weight value can be assigned. On the other hand, it can be determined that when the interval between two time points is longer, the user is less likely to use the corresponding brightness, and thus a lower continuity weight value can be assigned. According to an embodiment, the electronic device may calculate the continuity weight value as 0 when the interval between the two time points is greater than or equal to a predetermined value.
