Description

Electronic device, method, and non-transitory computer-readable storage medium for controlling brightness level

[0001] The following descriptions relate to electronic devices, methods, and non-transitory computer-readable storage media for controlling brightness levels.

[0002] An electronic device may include a display. The display may be used to display images. For example, the electronic device may support a function for controlling the brightness level of the display based on changes in the ambient lighting surrounding the electronic device.

[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

[0004] An electronic device is described. The electronic device may include a memory, including one or more storage media, and storing instructions. The electronic device may include an ambient light sensor. The electronic device may include a display. The electronic device may include at least one processor, including one or more processing circuits. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to detect an event for displaying a first image. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to acquire a second image, based on the event, the second image including a third region corresponding to a first region of the first image and brighter than the first region, and a fourth region corresponding to a second region of the first image and darker than the second region. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control a brightness level of the display that performs display of the second image provided in response to the event by setting a value to a first value for compensating for the fourth region being darker than the second region. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the brightness level of the display by setting the value to a second value lower than the first value based on recognizing through the light sensor that while the second image is displayed, the light level around the electronic device changes from a first light level lower than a threshold light level to a second light level higher than the threshold light level.

[0005] A method is described. The method can be executed in an electronic device having an illumination sensor and a display. The method can include an operation of detecting an event for displaying a first image. The method can include an operation of acquiring a second image, based on the event, including a third region corresponding to a first region of the first image and brighter than the first region, and a fourth region corresponding to a second region of the first image and darker than the second region. The method can include an operation of controlling a brightness level of the display that executes display of the second image provided in response to the event by setting a value for compensating for the fourth region being darker than the second region to a first value. The method can include an operation of controlling the brightness level of the display by setting the value to a second value lower than the first value based on recognizing through the illumination sensor that the illumination around the electronic device changes from a first illumination lower than a threshold illumination level to a second illumination higher than the threshold illumination level while the second image is displayed.

[0006] A non-transitory computer-readable storage medium is described. The non-transitory computer-readable storage medium may store one or more programs. The one or more programs may include instructions that, when executed by an electronic device having a light sensor and a display, cause the electronic device to detect an event for displaying a first image. The one or more programs may include instructions that, when executed by the electronic device, cause the electronic device to obtain, based on the event, a second image including a third region corresponding to a first region of the first image and brighter than the first region and a fourth region corresponding to a second region of the first image and darker than the second region. The one or more programs may include instructions that, when executed by the electronic device, cause the electronic device to control a brightness level of the display to perform display of the second image provided in response to the event by setting a value for compensating for the fourth region being darker than the second region to a first value. The one or more programs may include instructions that, when executed by the electronic device, cause the electronic device to control the brightness level of the display by setting the value to a second value lower than the first value based on recognizing through the light sensor that the light level around the electronic device has changed from a first light level lower than a threshold light level to a second light level higher than the threshold light level while the second image is displayed.

[0014] FIG. 8 is a block diagram of an electronic device within a network environment according to various embodiments.

[0015] FIG. 9 is a block diagram of a display module according to various embodiments.

[0016] An electronic device may include a display. The display may be used to display an image. For example, since the display is exposed to the environment surrounding the electronic device, the visual quality of the image may vary depending on changes in the environment. For example, the image may appear differently depending on the illumination of the environment. For example, since the image appears differently depending on the illumination of the environment, the electronic device may control the brightness level of the display depending on the illumination of the environment. For example, the electronic device may change the brightness level depending on changes in the illumination of the environment. Changing the brightness level is exemplified in the description of FIG. 1.

[0017] Figure 1 illustrates an example of controlling the brightness level of a display of an electronic device depending on the illumination around the electronic device.

[0018] Referring to FIG. 1, the electronic device (100) can display an image (140) at a first brightness level (131) on the display (120), as in state (191). For example, the first brightness level (131) can correspond to the illuminance (181) around the electronic device (100).

[0019] For example, the illuminance surrounding the electronic device (100) may change. For example, the illuminance may change from illuminance (181) to illuminance (182). Maintaining the brightness level of the display (120) displaying the image (140) at the first brightness level (131) corresponding to the illuminance (181) while the illuminance surrounding the electronic device (100) is illuminance (182) may reduce the visual quality of the image (140). For example, the electronic device (100) may change the state (191) to the state (192) according to the change from illuminance (181) to illuminance (182) for the visual quality of the image (140). For example, as in state (192), the electronic device (100) may display the image (140) on the display (120) at a second brightness level (132) changed from the first brightness level (131) according to the changed illuminance (182) from the illuminance (181) for the visual quality of the image (140). For example, the second brightness level (132) may correspond to the illuminance (182).

[0020] As described above, the electronic device (100) may support a function of controlling the brightness level of the display (120) (e.g., from a first brightness level (131) to a second brightness level (132)) according to a change in the illumination around the electronic device (100) (e.g., from an illumination level (181) to an illumination level (182)). As a non-limiting example, the function may be utilized for an electronic device (100) located outdoors. Components of the electronic device (100) that provide the function are exemplified within the description of FIG. 2.

[0021] Figure 2 is a simplified block diagram of an exemplary electronic device.

[0022] Referring to FIG. 2, the electronic device (100) may include at least a portion of the electronic device (801) of FIG. 8 or may correspond to at least a portion of the electronic device (801) of FIG. 8. The electronic device (100) may include a display (120), at least one processor (210), a memory (220), and a light sensor (230). The components illustrated above (e.g., the display (120), the processor (210), the memory (220), and the light sensor (230)) are merely exemplary. For example, the electronic device (100) may include other components (e.g., a power management integrated circuitry (PMIC) or a rechargeable battery). For example, some components may be omitted from the electronic device (100). For example, some components may be integrated into one component.

[0023] At least one processor (210) may include at least a portion of the processor (820) of FIG. 8, or may correspond to at least a portion of the processor (820) of FIG. 8. The at least one processor (210) may be used to control the display (120), the memory (220), and the sensor (230). The at least one processor (210) may be configured to cause the electronic device (100) to perform at least a portion of the operations illustrated in the descriptions of FIGS. 3 to 7 below. For example, the at least one processor (210) may perform at least a portion of the operations illustrated in the descriptions of FIGS. 3 to 7 below by executing instructions stored in the memory (220).

[0024] At least one processor (210) may be implemented as one or more integrated circuit (IC) chips and may perform various data processing operations. At least one processor (210) may include at least one electrical circuit and may individually or collectively perform distributed processing of instructions (or programs, data, etc.) stored in a memory (220). At least one processor (210) may include a processor assembly including one or more processing circuits. At least one processor (210) may include any processing circuit operative to control the execution and operations of one or more components of the electronic device (100).

[0025] At least one processor (210) may include at least a portion of the processor (820) of FIG. 8 or may correspond to at least a portion of the processor (820) of FIG. 8. For example, at least one processor (210) may include a central processing unit (CPU) (or central processing circuit). For example, at least one processor (210) may include a graphic processing unit (GPU) (or graphic processing circuit). For example, at least one processor (210) may include a display processing unit (DPU) (or display control circuit) for the display (120). For example, at least one processor (210) may include a memory controller (or memory control circuit) for the memory (220) (e.g., volatile memory) and / or a storage controller (or storage control circuit) for the memory (202) (e.g., non-volatile memory). For example, at least one processor (210) may include a sensor interface (or sensor hub) (or sensor control circuit) for a light sensor (230).

[0026] The display (120) may include at least a portion of the display module (860) of FIGS. 8 and 9 or may correspond to at least a portion of the display module (860) of FIGS. 8 and 9. The display (120) may be used to display an image (e.g., visual information, visual data, and / or a screen). For example, the display (120) may be used to display an image acquired (or generated) (or rendered) by at least one processor (210). For example, the display (120) may be used to display an image provided from at least one processor (210).

[0027] Although not shown in FIG. 2, the display (120) may include a display driver circuit (e.g., a display driver IC (DDI) (930) of FIG. 9) and a display panel (e.g., a display (910) of FIG. 9). For example, the display driver circuit may be used to display the image on the display panel. As a non-limiting example, the display driver circuit may include a memory (e.g., a graphic random access memory (GRAM)) configured to store information about at least a portion of the image. As a non-limiting example, the display driver circuit may not include the memory. As a non-limiting example, the display driver circuit may be configured to operate for a command mode of a mobile industry processor interface (MIPI) display serial interface (DSI), a video mode of a MIPI DSI, and / or a video hybrid mode of a MIPI DSI. As a non-limiting example, the display driver circuit may be configured to perform at least some of the operations illustrated in the descriptions of FIGS. 3 to 7 below. For example, some of the operations of at least one processor (210) illustrated in the descriptions of FIGS. 3 to 7 may be replaced by at least one operation of the display driver circuit. For example, the display driver circuit may control the display panel based on control data (e.g., a control command) from at least one processor (210).

[0028] The memory (220) may include one or more storage media (or one or more storage devices). For example, the memory (220) may include a memory assembly including one or more storage media. For example, the one or more storage media may include a hard drive, flash memory, permanent memory such as read-only memory (ROM) (e.g., non-volatile memory (834) of FIG. 8), semi-permanent memory such as random access memory (RAM) (e.g., volatile memory (832) of FIG. 8), any other suitable type of storage (or storage assembly), or any combination thereof. The memory (220) may include a cache memory, which is one or more different types of memory used to temporarily store data for a function or feature of the electronic device (100). As a non-limiting example, the cache memory may be included within the processor (210). The memory (220) may be fixedly embedded within the electronic device (100) or incorporated into one or more suitable types of components (e.g., a subscriber identity module (SIM) card and / or a secure digital (SD) card) that may be repeatedly inserted into and removed from the electronic device (100).

[0029] For example, the memory (220) may store one or more software applications, such as an operating system (or system) software application, a firmware software application, a driver software application, a plug-in (e.g., add-in, add-on, and / or applet) software application, and / or any other suitable software applications. For example, the one or more software applications may include instructions executable by at least one processor (210). For example, the memory (220) may store instructions callable by an application programming interface (API). For example, the memory (220) may store instructions within a library.

[0030] The memory (220) may include at least a portion of the memory (830) of FIG. 8 or correspond to at least a portion of the memory (830) of FIG. 8. The memory (220) may be configured to store instructions that cause the electronic device (100) to perform at least a portion of the operations illustrated in the descriptions of FIGS. 3 through 7 below. The instructions may be executable by at least one processor (210).

[0031] The light sensor (230) may be configured to obtain data on the state of light surrounding the electronic device (100). For example, the light sensor (230) may be configured to obtain data representing the illuminance. As a non-limiting example, the light sensor (230) may be implemented as a camera (not shown) of the electronic device (100) facing a first direction toward which the display (120) faces and / or a camera (not shown) of the electronic device (100) facing a second direction opposite to the first direction.

[0032] For example, the electronic device (100) can perform various operations to control the brightness level of the display (120) according to changes in the illumination around the electronic device (100) using the components illustrated in the description of FIG. 2.

[0033] For example, the electronic device (100) can control the brightness level of a display (120) that displays a second image generated from a first image according to changes in illuminance. This operation is exemplified in the description of FIG. 3.

[0034] FIG. 3 is a flowchart illustrating an exemplary method for controlling the brightness level of a display that displays a second image generated from a first image according to changes in illuminance.

[0035] Referring to FIG. 3, in operation 301, at least one processor (210) may detect an event for displaying a first image. For example, the event may be detected while the brightness level of the display (120) is set to a first brightness level. As a non-limiting example, operation 301 may be executed while the illuminance around the electronic device (100) is a first illuminance. For example, the first brightness level may correspond to the first illuminance. For example, at least one processor (210) may recognize that the illuminance is the first illuminance based on data (or a signal) acquired from the illuminance sensor (230) while operation 301 is executed. As a non-limiting example, the first illuminance may be lower than a threshold illuminance exemplified below.

[0036] As a non-limiting example, a file including the first image may include the first image and metadata available for the first image. The metadata will be described in more detail below.

[0037] The above event may represent any suitable event that causes the display (120) to display the first image. For example, the event may represent an event that changes (or switches) the image displayed on the display (120) to the first image. The event is exemplified in the description of FIG. 4.

[0038] Figure 4 illustrates an example of an event.

[0039] Referring to FIG. 4, at least one processor (210) may display an image (401) on the display (120), such as a state (400). For example, the image (401) may include a thumbnail image (421) corresponding to the first image exemplified in the description of FIG. 3. For example, the thumbnail image (421) may include a reduced image of the first image. For example, at least one processor (210) may receive a touch input (410) for the thumbnail image (421) within the state (400). For example, at least one processor (210) may detect the event by receiving the touch input (410). For example, at least one processor (210) may change the state (400) to the state (450) based on the touch input (410). For example, a touch input (410) may cause a change from a state (400) to a state (450). For example, at least one processor (210) may change a state (400) to a state (450) based on (or in response to) the touch input (410). For example, at least one processor (210) may display a second image (402) generated from the first image on the display (120) within the state (450).

[0040] Referring back to FIG. 3, at operation 302, at least one processor (210) may acquire a second image, based on the event (or based on the detection), that includes a third region corresponding to the first region of the first image and darker than the first region, and a fourth region corresponding to the second region of the first image and darker than the second region.

[0041] As a non-limiting example, at least one processor (210) may generate the second image using the first image and store the generated second image in the memory (220) before detecting the event (e.g., before operation 301). For example, at least one processor (210) may obtain the second image from the memory (220) based on the event.

[0042] As a non-limiting example, at least one processor (210) may obtain the second image by generating the second image using the first image based on the event.

[0043] Generating the second image including the third region that is brighter than the first region of the first image and the fourth region that is darker than the second region of the first image is exemplified within the description of FIG. 5.

[0044] Figure 5 illustrates an exemplary method for generating a second image by applying map information to a first image.

[0045] Referring to FIG. 5, a file (not shown) including a first image (511) may include the first image (511) and map information (510). As a non-limiting example, the map information (510) may be included in metadata (not shown) for the first image (511) included in the file.

[0046] For example, a first image (511) may include a first region (501) and a second region (502). For example, map information (510) may be available for a third region (513) of the second image (402) having a second grayscale range that is wider than a first grayscale range of the first region (501). For example, the map information (510) may be applied to the first image (511) for visually emphasizing the third region (513) with respect to the first region (501). For example, the map information (510) may be available for converting the first image (511), which is a standard dynamic range (SDR) image, into a second image (402) so that the first image (511) is displayed as a high dynamic range (HDR) image. The map information (510) may be referred to as a gain map.

[0047] For example, at least one processor (210) may generate a second image (402) by applying map information (510) to a first image (511). As a non-limiting example, since the second image (402) is obtained by applying the map information (510) to the first image (511), a third area (513) of the second image (402) may be brighter than a first area (501) of the first image (511). For example, a maximum value of the second grayscale range may be higher than a maximum value of the first grayscale range. As a non-limiting example, since the second image (402) is obtained by applying the map information (510) to the first image (511), a fourth area (514) of the second image (402) may be darker than a second area (502) of the first image (511).

[0048] Referring again to FIG. 3, at operation 303, at least one processor (210) may control a brightness level of a display (120) that executes display of the second image provided in response to the event detected at operation 301 by setting a value for compensating for the fourth region being darker than the second region to a first value. As a non-limiting example, the value may be referenced as an 'SDR to HDR' ratio. As a non-limiting example, the value may be referenced as display control information.

[0049] For example, referring to FIG. 5, since the fourth area (514) of the second image (402) is darker than the second area (502) of the first image (511), at least one processor (210) can control the brightness level of the display (120) using the first value so that the brightness of the fourth area (514) of the second image (402) displayed on the display (120) corresponds to the brightness of the second area (502) of the first image (511) based on the event.

[0050] As a non-limiting example, when the illuminance around the electronic device (100) before (or immediately before) detecting the event is a first illuminance, the brightness level of the display (120) may be set to a first brightness level corresponding to the first illuminance (e.g., the first brightness level exemplified in the description of FIG. 3) according to the function. For example, when the illuminance after (or immediately after) detecting the event is the first illuminance, the brightness level of the display (120) displaying the second image (402) may be set to a second brightness level higher than the first brightness level. For example, at least one processor (210) may change the brightness level of the display (120) from the first brightness level to the second brightness level according to the display of the second image (402), even if the illuminance is maintained at the first illuminance. For example, the change from the first brightness level to the second brightness level may be executed according to the first value. For example, the first value may correspond to the difference between the first brightness level and the second brightness level. For example, the first value may correspond to the difference between the brightness of the second area (502) of the first image (511) and the brightness of the fourth area (514) of the second image (402).

[0051] For example, the first value may be included in the metadata within the file including the first image (511). For example, the metadata may indicate that the value is the first value. For example, at least one processor (210) may obtain the first value from the metadata based on the event, and control the brightness level of the display (120) that executes display of the second image provided in response to the event using the first value (or by setting the value to the first value).

[0052] For example, at least one processor (210) may display a second image (402) on the display (120), such as in state (450), according to the control of the brightness level exemplified above. For example, a fourth region (514) of the second image (402) displayed on the display (120) may have a brightness corresponding to a second region (502) of the first image (511), such as in state (450).

[0053] Referring again to FIG. 3, at least one processor (210) may obtain data representing the illuminance around the electronic device (100) from the illuminance sensor (230) used for the function while the second image is displayed on the display (120) according to operation 303. For example, at least one processor (210) may recognize a change in the illuminance using the illuminance sensor (230) while the second image is displayed on the display (120) according to operation 303.

[0054] At operation 304, at least one processor (210) may determine, verify, identify, or monitor whether the illuminance is lower than a threshold illuminance based on recognizing a change in the illuminance. As a non-limiting example, operation 304 (e.g., comparing the illuminance represented by data acquired via the illuminance sensor (230) to the threshold illuminance) may be executed under a condition that the function is activated within the electronic device (100) and the second image is displayed on the display (120) in response to an event with respect to the first image.

[0055] For example, at least one processor (210) may execute operation 305 based on recognizing through the light sensor (230) that the illuminance changes from the first illuminance lower than the threshold illuminance to the second illuminance higher than the threshold illuminance while the second image is displayed according to operation 303, and may execute operation 306 based on recognizing through the light sensor (230) that the illuminance changes from the first illuminance lower than the threshold illuminance to the third illuminance higher than the first illuminance and lower than the threshold illuminance while the second image is displayed according to operation 303.

[0056] In operation 305, at least one processor (210) can control the brightness level of the display (120) by setting the value to a second value lower than the first value under the condition that the illuminance changes from the first illuminance to the second illuminance. This operation is exemplified in the description of FIG. 6.

[0057] FIG. 6 illustrates an exemplary method for controlling the brightness level of a display displaying a second image according to changes in illuminance.

[0058] Referring to FIG. 6, a chart (600) represents a change in brightness of a display (120) (a display (120) displaying the second image (e.g., the second image (402))) that changes according to a change in illuminance. The horizontal axis of the chart (600) represents the illuminance, and the vertical axis of the chart (600) represents the brightness.

[0059] A line (601) in the chart (600) is related to the luminance (hereinafter, first luminance) of a first position, which is a position in a third area (513) of a second image (402) displayed on the display (120) according to operation 303. For example, the line (601) represents the first luminance that changes according to the change in the illuminance. A line (602) in the chart (600) is related to the luminance (hereinafter, second luminance) of a second position, which is a position in a fourth area (514) of a second image (402) displayed on the display (120) according to operation 303. For example, the line (602) represents the second luminance that changes according to the change in the illuminance. For example, since line (601) represents the relationship between the illuminance and the first luminance, and line (602) represents the relationship between the illuminance and the second luminance, the difference (610) (or ratio (610)) between the first luminance D1 represented by line (601) when the illuminance is A and the second luminance D2 represented by line (602) when the illuminance is A corresponds to the first value. For example, the difference (or ratio) between the luminance represented by line (601) and the luminance represented by line (602) for the same illuminance represents the above value.

[0060] As a non-limiting example, operation 305 executed by at least one processor (210) may be represented as a line (601) within a luminance range (621) (e.g., including the second luminance) and a line (602) within the luminance range (621). For example, a minimum luminance A in the luminance range (621) represents the threshold luminance. For example, since the first luminance represented by the line (601) within the illuminance range (621) is maintained according to saturation of the luminance and the second luminance represented by the line (602) within the illuminance range (621) is increased, the difference (or ratio) between the first luminance represented by the line (601) within the illuminance range (621) and the second luminance represented by the line (602) within the illuminance range (621) corresponds to the second value being lower than the first value. For example, as represented by line (601) within the illuminance range (621) and line (602) within the illuminance range (621), at least one processor (210) can control the brightness level of the display (120) displaying the second image by decreasing the value as the illuminance recognized by the illuminance sensor (230) within the illuminance range (621) (e.g., illuminance higher than the threshold illuminance) increases. As a non-limiting example, at least one processor (210) can control the brightness level of the display (120) by acquiring the second image including the fourth region having the second brightness higher than the first brightness of the fourth region of the second image acquired while the illuminance was the first illuminance, based on recognizing that the illuminance changed from the first illuminance to the second illuminance while the second image was displayed.As a non-limiting example, at least one processor (210) can control the brightness level of the display (120) by setting the value to the second value based on recognizing that the illuminance changes from the first illuminance to the second illuminance while the second image is displayed, upon acquiring the second image including the fourth region having the second brightness higher than the first brightness of the fourth region of the second image acquired while the illuminance is at the first illuminance. As a non-limiting example, at least one processor (210) can control the brightness level of the display (120) based on recognizing that the illuminance changes from the first illuminance to the second illuminance while the second image is displayed, upon acquiring the second image including the fourth region having the second brightness and the third region having the fourth brightness corresponding to (or substantially the same as) the third brightness of the third region of the second image acquired while the illuminance is at the first illuminance. As a non-limiting example, at least one processor (210) can control the brightness level of the display (120) by setting the value to the second value based on acquiring the second image including the third region having the fourth brightness and the fourth region having the second brightness, based on recognizing that the illuminance changes from the first illuminance to the second illuminance while the second image is displayed.

[0061] As a non-limiting example, the electronic device (100) may support another function for controlling the contrast ratio of an image displayed on a display (120) of the electronic device (100) located outdoors to enhance the visibility of the image. As a non-limiting example, the other function may be activated (or executed) when the illuminance is B within the illuminance range (621). For example, a difference (611) (or ratio (611)) between a first luminance D1 represented by line (601) when the illuminance is B and a second luminance D3 represented by line (602) when the illuminance is B may be set to a value to reduce the occurrence of side effects (e.g., false contours) in the second image displayed on the display (120) according to the other function.

[0062] Referring again to FIG. 3, at operation 306, at least one processor (210) may control the brightness level of the display (120) by maintaining the value at the first value under the condition that the illuminance changes from the first illuminance to the third illuminance that is higher than the first illuminance and lower than the threshold illuminance. This operation is exemplified in the description of FIG. 6.

[0063] Referring back to FIG. 6, operation 306 executed by at least one processor (210) may be represented as a line (601) within a luminance range (622) (e.g., including the first luminance and the third luminance) and a line (602) within the luminance range (622). For example, since the first luminance represented by the line (601) within the luminance range (622) increases according to a first slope, and the second luminance represented by the line (602) within the luminance range (622) increases according to a second slope that is lower than the first slope, a difference (or ratio) between the first luminance represented by the line (601) within the luminance range (622) and the second luminance represented by the line (602) within the luminance range (622) corresponds to the first value. For example, as represented by line (601) within the illuminance range (622) and line (602) within the illuminance range (622), at least one processor (210) can control the brightness level of the display (120) displaying the second image by maintaining the value at the first value independently of an increase in the illuminance recognized through the illuminance sensor (230) within the illuminance range (622). It should be noted that within this document, maintaining the value as the first value only indicates that the ratio between the first luminance represented by the line (601) within the illuminance range (622) and the second luminance represented by the line (602) within the illuminance range (622) is maintained, but does not indicate that the first luminance represented by the line (601) within the illuminance range (622) and the second luminance represented by the line (602) within the illuminance range (622) are fixed.

[0064] As described above, the electronic device (100) can enhance the quality of the service provided through the display (120) by executing the operations exemplified in the description of FIG. 3 according to the change in illumination that occurs while displaying the second image.

[0065] As a non-limiting example, the electronic device (100) may be positioned within an environment having a higher illuminance (e.g., the fourth illuminance within the description of FIG. 7 ) than the second illuminance. For example, the electronic device (100) may support operations based on other threshold illuminances higher than the threshold illuminance illustrated above for display within the environment. Such operations are exemplified within the description of FIG. 7 .

[0066] FIG. 7 is a flowchart illustrating an exemplary method for controlling the brightness level of a display by stopping the display of a second image and executing the display of a first image.

[0067] Referring to FIG. 7, in operation 701, at least one processor (210) may determine, verify, identify, or monitor whether the illuminance higher than the threshold illuminance is lower than the other threshold illuminance based on recognizing a change in the illuminance through the illuminance sensor (230). As a non-limiting example, operation 701 (e.g., comparing the illuminance represented by data acquired through the illuminance sensor (230) with the other threshold illuminance) may be executed under a condition that the function is activated within the electronic device (100) and the second image is displayed on the display (120) in response to an event with respect to the first image.

[0068] For example, at least one processor (210) may execute operation 702 based on recognizing through the light sensor (230) that the illuminance changes from the first illuminance to the second illuminance that is higher than the threshold illuminance and lower than the other threshold illuminance while the second image is displayed according to operation 303, and may execute operation 703 based on recognizing through the light sensor (230) that the illuminance changes from the first illuminance to a fourth illuminance that is higher than the other threshold illuminance while the second image is displayed according to operation 303.

[0069] In operation 702, at least one processor (210) may control the brightness level of the display (120) by setting the value to a second value lower than the first value under the condition that the illuminance changes from the first illuminance to the second illuminance. For example, operation 702 may correspond to operation 305 of FIG. 3.

[0070] In operation 703, at least one processor (210) can control the brightness level of the display (120) by stopping the display of the second image and executing the display of the first image under the condition that the illuminance changes from the first illuminance to the fourth illuminance. This operation is exemplified in the description of FIG. 6.

[0071] Referring to FIG. 6, operation 703 executed by at least one processor (210) may be represented by a line (601) that is not defined within a luminance range (623) and a line (602) within a luminance range (623) (e.g., including the fourth luminance). For example, C, which is a minimum luminance within the luminance range (623), represents the other threshold luminance. For example, like line (601) that is not defined within the luminance range (623), at least one processor (210) may stop displaying the second image on the display (120) and display the first image on the display (120) based on recognizing the fourth luminance through the luminance sensor (230). As a non-limiting example, at least one processor (210) may increase the brightness level of the display (120) displaying the first image changed from the second image as the illumination recognized through the illumination sensor (230) increases within the illumination range (623).

[0072] As described above, the electronic device (100) can support a first function of displaying an SDR image shown as an HDR image and a second function of changing the brightness level of the display (120) according to changes in the illumination around the electronic device (100). For example, the electronic device (100) can provide enhanced services by executing the operations exemplified above under conditions in which both the first function and the second function are executed.

[0073] The above exemplified operations may also be executed by an electronic device (801) as exemplified in the description below.

For example, the touch sensor IC (953) may detect a touch input or a hovering input by measuring a change in a signal (e.g., voltage, light amount, resistance, or charge amount) for a specific location of the display (910). The touch sensor IC (953) may provide information (e.g., location, area, pressure, or time) regarding the detected touch input or hovering input to the processor (820). According to one embodiment, at least a portion of the touch circuit (950) (e.g., touch sensor IC (953)) may be included as part of the display driver IC (930), or as part of the display (910), or as part of another component (e.g., auxiliary processor (823)) disposed external to the display module (860).

The at least one processor may be configured to detect an event for displaying a first image (e.g., operation 301), acquire a second image based on the event, including a third region corresponding to a first region of the first image and brighter than the first region and a fourth region corresponding to a second region of the first image and darker than the second region (e.g., operation 302), set a value for compensating for the fourth region darker than the second region to a first value, thereby controlling a brightness level of the display that executes display of the second image provided in response to the event (e.g., operation 303), and control the brightness level of the display by setting the value to a second value lower than the first value based on recognizing through the light sensor that the light level around the electronic device changes from a first light level lower than a threshold light level to a second light level higher than the threshold light level while the second image is displayed (e.g., operation 305).

[0101] The at least one processor may be configured to control the brightness level of the display by maintaining the value at the first value based on recognizing through the light sensor that the illuminance changes from the first illuminance to a third illuminance higher than the first illuminance and lower than the threshold illuminance while the second image is displayed (e.g., operation 306).

[0102] For example, the second illuminance may be lower than another threshold illuminance that is higher than the threshold illuminance. The at least one processor may be configured to control the brightness level of the display by stopping the display of the second image and executing the display of the first image based on recognizing through the illuminance sensor that the illuminance changes from the first illuminance to a fourth illuminance that is higher than the other threshold illuminance while the second image is displayed (e.g., operation 703).

[0103] The at least one processor may be configured to control the brightness level of the display by setting the value to the second value based on recognizing that the illuminance has changed from the first illuminance to the second illuminance, and acquiring the second image including the fourth region having a second brightness higher than the first brightness of the fourth region of the second image acquired while the illuminance was at the first illuminance (e.g., operation 305).

[0104] The at least one processor may be configured to control the brightness level of the display by setting the value to the second value based on recognizing that the illuminance has changed from the first illuminance to the second illuminance, and acquiring the second image including the third region having the fourth brightness corresponding to the third brightness of the third region of the second image acquired while the illuminance was at the first illuminance, and the fourth region having the second brightness (e.g., operation 305).

[0105] For example, the first value may correspond to the difference between the third brightness of the second region and the first brightness.

[0106] The at least one processor may be configured to, prior to detecting the event, generate the second image, store the generated second image in the memory, and, based on the event, obtain the second image from the memory (e.g., operation 302).

[0107] The at least one processor may be configured to obtain the second image by generating the second image based on the event (e.g., operation 302).

[0108] For example, the first value may be obtained from metadata within a file stored within the memory and including the first image.

[0109] The at least one processor may be configured to obtain the second image by generating the second image by applying map information in the metadata for the third region having a second tone range wider than the first tone range of the first region to the first image based on the event, or to obtain the second image generated by applying the map information for the third region for the second tone range to the first image from the memory (e.g., operation 302).

[0110] For example, the map information may be applied to the first image for the third region that is visually highlighted with respect to the first region.

[0111] As described above, a method can be executed in an electronic device having an illumination sensor and a display. The method can include: detecting an event for displaying a first image; acquiring a second image based on the event, the second image including a third region corresponding to a first region of the first image and brighter than the first region and a fourth region corresponding to a second region of the first image and darker than the second region; controlling a brightness level of the display, which executes display of the second image provided in response to the event, by setting a value for compensating for the fourth region being darker than the second region to a first value; and controlling the brightness level of the display by setting the value to a second value lower than the first value based on recognizing through the illumination sensor that the illumination around the electronic device changes from a first illumination lower than a threshold illumination level to a second illumination higher than the threshold illumination level while the second image is displayed.

[0112] The method may include an operation of controlling the brightness level of the display by maintaining the value at the first value based on recognizing through the light sensor that the illuminance has changed from the first illuminance to a third illuminance that is higher than the first illuminance and lower than the threshold illuminance while the second image is displayed.

[0113] For example, the second illuminance may be lower than another threshold illuminance that is higher than the threshold illuminance. The method may include an operation of controlling the brightness level of the display by stopping the display of the second image and executing the display of the first image based on recognizing through the illuminance sensor that the illuminance has changed from the first illuminance to a fourth illuminance that is higher than the other threshold illuminance while the second image is displayed.

[0114] For example, the operation of controlling the brightness level of the display based on recognizing that the illuminance has changed from the first illuminance to the second illuminance may include the operation of controlling the brightness level of the display by setting the value to the second value based on recognizing that the illuminance has changed from the first illuminance to the second illuminance, and acquiring the second image including the fourth region having a second brightness higher than the first brightness of the fourth region of the second image acquired while the illuminance was at the first illuminance.

[0115] For example, the operation of controlling the brightness level of the display based on recognizing that the illuminance has changed from the first illuminance to the second illuminance may include the operation of controlling the brightness level of the display by setting the value to the second value based on recognizing that the illuminance has changed from the first illuminance to the second illuminance, obtaining the second image including the third region having the fourth brightness corresponding to the third brightness of the third region of the second image obtained while the illuminance was at the first illuminance, and the fourth region having the second brightness.

[0116] A non-transitory computer-readable storage medium as described above may store one or more programs. The one or more programs may include instructions that, when executed by an electronic device having an illumination sensor and a display, cause the electronic device to detect an event for displaying a first image, acquire a second image based on the event, the second image including a third region corresponding to a first region of the first image and brighter than the first region and a fourth region corresponding to a second region of the first image and darker than the second region, and set a value to compensate for the fourth region being darker than the second region to a first value, thereby controlling a brightness level of the display to execute display of the second image provided in response to the event, and control the brightness level of the display by setting the value to a second value lower than the first value based on recognizing through the illumination sensor that the illumination around the electronic device changes from a first illumination lower than a threshold illumination level to a second illumination higher than the threshold illumination level while the second image is displayed.

[0117] The one or more programs may include instructions that cause the electronic device to control the brightness level of the display by maintaining the value at the first value based on recognizing through the light sensor that the illuminance has changed from the first illuminance to a third illuminance that is higher than the first illuminance and lower than the threshold illuminance while the second image is displayed.

[0118] For example, the second illuminance may be lower than another threshold illuminance that is higher than the threshold illuminance. The one or more programs may include instructions that cause the electronic device to control the brightness level of the display by stopping the display of the second image and executing the display of the first image based on recognizing through the illuminance sensor that the illuminance has changed from the first illuminance to a fourth illuminance that is higher than the other threshold illuminance while the second image is displayed.

[0119] The one or more programs may include instructions that cause the electronic device to control the brightness level of the display by acquiring the second image including the fourth region having a second brightness higher than the first brightness of the fourth region of the second image acquired while the illuminance was at the first illuminance, based on recognizing that the illuminance has changed from the first illuminance to the second illuminance.

A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0124] Various embodiments of the present document may be implemented as software (e.g., a program (840)) including one or more instructions stored in a storage medium (e.g., an internal memory (836) or an external memory (838)) readable by a machine (e.g., an electronic device (801)). For example, a processor (e.g., a processor (820)) of the machine (e.g., an electronic device (801)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.
