The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)) and supporting direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with an external electronic device 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 traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))).

A first display area of ​​a display (e.g., a flexible display) can be provided in the first housing, and a second display area of ​​the display can be provided in the second housing. The foldable housing structure can be implemented in an inward folding manner, in which the first display area and the second display area face each other when the electronic device 101 is in a folded state. Alternatively, the foldable housing structure can be implemented in an out-folding manner, in which the first display area and the second display area are opposite to each other when the electronic device 101 is in a folded state.

[0059] A slidable (or rollable) housing structure can be applied to an electronic device (e.g., a smart phone, a tablet PC, a notebook PC) 101. The electronic device 101 may include a slidable housing and a rollable display (e.g., a flexible display), the slidable housing including a housing (or a first housing) and a slider (or a second housing), a track structure (e.g., a track structure having a gear combination between a rack gear and a pinion) for sliding the slider into and out of the housing. The slider may be divided into a portion that can slide into the housing (hereinafter, a slide-in portion) and a portion that remains exposed to the outside. The entire display (or most of the display area) may be exposed to the outside through the front surface in the slide-out state, and in the slide-out state, the entirety of the slide-in portion of the slider slides out of the housing (in other words, in the first state, the open state, the extended state, or the unfolded state). When the slide-in portion of the slider slides into the housing, the display may also be received inside the housing. The display can also be divided into a portion (e.g., a first display area or a first portion) that remains exposed to the outside and a portion (e.g., a second display area, a second portion, or a bendable portion) that can slide into the housing. When switched to the slide-in state (in other words, in the second state, the closed state, the reduced state, or the rolled-in state), in the slide-in state, the entire slide-in portion of the slider slides into the housing, and the entire second display area of ​​the display can be accommodated inside the housing. In an embodiment, when switching from the slide-out state to the slide-in state, a portion of the display (e.g., the second display area) can be moved to the rear surface via the side surface instead of sliding into the housing. As illustrated above, the electronic device 101 can have a sliding structure in which a portion of the display slides into the housing or a sliding structure in which a portion of the display moves from the front surface to the rear surface. In the display, only the portion exposed by the front surface can be determined as an activated display area (hereinafter, an activation area) for displaying visual information. The portion that slides into the housing or moves to the rear surface can be determined as an inactive area in which visual information is not displayed.

The side surface frame structure 210 may be made of a combination of a metal (e.g., SUS) and a polymer. The side surface frame structure 210 may form a side surface surrounding a space between the first surface and the second surface. According to an embodiment, a structure including a first surface, a second surface, and a side surface may be referred to as a shell (or shell structure).

[0062] The printed circuit boards 240 and 241 may be arranged to be supported by the first support member 211 and / or the second support member 260. The first support member 211 may be coupled to the side surface frame structure 210. The first support member 211 may include a structure (e.g., metal or polymer) extending from the side surface frame structure 210.

[0063] Figures 3a to 3f An electronic device 300 having a foldable housing structure in an inward folding manner according to an embodiment is shown. Specifically, Figure 3a and Figure 3b shows the front surface of the electronic device 300 in an unfolded (flat or open) state, Figure 3c The rear surface of the electronic device 300 in a folded (or closed) state is shown. Figure 3d The rear surface of the electronic device 300 in the unfolded state is shown. Figure 3e The front surface of the electronic device 300 is shown in a partially folded state (in other words, a partially unfolded state, or an intermediate state (free stop state) between the fully folded state and the fully unfolded state), and Figure 3f is an exploded perspective view of the electronic device 300 .

[0064] refer to Figures 3a to 3f , the electronic device 300 (for example, Figure 1The electronic device 101 in the embodiment may include a foldable housing including a first housing 310, a second housing 320, and a hinge assembly 340, the hinge assembly 340 connecting the first housing 310 and the second housing 320 so that the second housing 320 can rotate relative to the first housing 310. The electronic device 300 may include a flexible or foldable display 399 and a sensor module (e.g., Figure 1 Sensor module 176 in.

[0065] The display 399 may be arranged from the first housing 310 across the hinge assembly 340 to the second housing 320. The display 399 may be divided into a first display area 311 arranged in the internal space of the first housing 310 and a second display area 321 arranged in the internal space of the second housing 320 based on the folding axis A. When viewed from the front, a sensor module (e.g., a light sensor) may be arranged below the sensor area (or light-transmitting area) 342a of the first display area 311. The position and / or size of the sensor area 342a within the first display area 311 may be determined by the position and / or size of the illuminance sensor arranged thereunder. For example, the size (e.g., diameter) of the sensor area 342a may be determined based on the field of view (FOV) of the illuminance sensor. In an embodiment, the sensor area 342a may be configured to have a lower pixel density and / or a lower wiring density than the surrounding area in order to improve light transmittance.

[0066] The hinge assembly 340 can be implemented in a folding manner so that when the electronic device 300 is moved from the unfolded state (eg, Figure 3a state) to the collapsed state (for example, Figure 3c 310 and 320. When the foldable housings 310 and 320 are in a state in which the two display areas 311 and 321 face each other, the two display areas 311 and 321 face each other. For example, when the electronic device 300 is in an unfolded state, the two display areas 311 and 321 may face substantially the same direction. When the electronic device switches from the unfolded state to the folded state, the two display areas 311 and 321 may rotate in the direction in which they face each other. The hinge assembly 340 may be configured so that the foldable housings 310 and 320 have resistance to rotation. When an external force exceeding the resistance is applied to the foldable housings 310 and 320, the foldable housings 310 and 320 may rotate.

[0067] Based on the angle formed between the two display areas 311 and 321, the state of the electronic device 300 can be defined. For example, when the angle between the two display areas 311 and 321 is about 180 degrees, the state of the electronic device 300 can be defined as an unfolded (flat or open) state. When the angle between the two display areas 311 and 321 is between about 0 degrees and 10 degrees, the state of the electronic device 300 can be defined as a folded (or closed) state. When the two display areas 311 and 321 form an angle that is greater than the angle in the folded state and less than the angle in the unfolded state (for example, between about 10 degrees and 179 degrees), the state of the electronic device 300 can be defined as an intermediate state (in other words, a partially folded or partially unfolded state), such as Figure 3e shown.

[0068] Based on the state of the electronic device 300, an activation area on which visual information (e.g., text, image, or icon) is to be displayed can be determined on the display 399. For example, when the electronic device 300 is in the intermediate state, the processor 120 can determine two or one of the first display area 311 and the second display area 321 as the activation area. The processor 120 can determine the first display area 311 or the second display area 321 with relatively less movement as the activation area. For example, when the user holds the housing of the electronic device 300 with one hand and opens the other housing with a finger (e.g., thumb) of the same hand or the other hand, the processor 120 can switch from the folded state to the intermediate state, and therefore, the electronic device 300 can determine the display area of ​​the housing (e.g., housing with relatively less movement) held as the activation area. When the electronic device 300 is in the unfolded state, the entire display area of ​​the display 399 (both the first display area 311 and the second display area 321) can be determined as the activation area.

[0069] According to an embodiment, in the unfolded state, the first housing 310 may include a first surface (first display area) 311 facing a first direction (e.g., front direction) (z-axis direction) and a second surface 312 facing a second direction (e.g., rear direction) (-z-axis direction) opposite to the first surface 311. In the unfolded state, the second housing 320 may include a third surface (second display area) 321 facing the first direction (e.g., z-axis direction) and a fourth surface 322 facing the second direction (e.g., -z-axis direction). The electronic device 300 may operate in such a manner that the first surface 311 of the first housing 310 and the third surface 321 of the second housing 320 face the same first direction (e.g., z-axis direction) in the unfolded state, and the first surface 311 and the third surface 321 face each other in the folded state. The electronic device 300 may operate in such a manner that the second surface 312 of the first housing 310 and the fourth surface 322 of the second housing 320 face the same second direction (-z-axis direction) in the unfolded state, and the second surface 312 and the fourth surface 322 face opposite directions to each other in the folded state.

In a certain embodiment, the sub-display 331 may be provided on the fourth surface 322 of the second housing 320.

[0075] According to an embodiment, the electronic device 300 may be operated to maintain the intermediate state using the hinge assembly 340. In this case, the electronic device 300 may display different contents on a first display area corresponding to the first surface 311 and a second display area corresponding to the third surface 321.

The sound output device may include, for example, a call receiver 406 and a speaker 407. According to an embodiment, the sound may be output to the outside from the speaker 407 through at least one speaker hole formed at a position (e.g., the fifth side surface 4212) that is always exposed to the outside, regardless of the sliding state. According to an embodiment, the connector port 408 may be exposed to the outside through a connector port hole formed in the second housing 420 in the slid-out state.

In a certain embodiment, the call receiver 406 may include a speaker (e.g., a piezoelectric speaker) that operates without a separate speaker hole.

[0092] The sensor modules 404 and 417 may generate an electrical signal or data value corresponding to an internal operating state or an external environmental state of the electronic device 400. The sensor modules 404 and 417 may include, for example, a first sensor module 404 (e.g., a proximity sensor or an illumination sensor) disposed on the front surface of the electronic device 400 and / or a second sensor module 417 (e.g., a heart rate monitoring (HRM) sensor) disposed on the rear surface of the electronic device 400. According to an embodiment, when viewed from the front of the electronic device 400, the first sensor module 404 may be disposed below the rollable display 430. According to an embodiment, the first sensor module 404 and / or the second sensor module 417 may include at least one of a proximity sensor, an illumination sensor, a time of flight (TOF) sensor, an ultrasonic sensor, a fingerprint recognition sensor, a posture sensor, a gyroscope sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, or a humidity sensor.

[0093] The camera module may include a first camera module 405 disposed on the front surface of the electronic device 400 and a second camera module 416 disposed on the rear surface of the electronic device 400. According to an embodiment, the electronic device 400 may further include a flash (not shown) located near the second camera module 416. According to an embodiment, the camera modules 405 and 416 may include one or more lenses, image sensors, and / or image signal processors. According to an embodiment, when viewed from the front of the electronic device 400, the first camera module 405 may be disposed below the rollable display 430 and configured to capture an object through a portion of the activation area of ​​the rollable display 430.

[0094] According to an embodiment, the first camera module 405 and / or the first sensor module 404 may be arranged to communicate with the external environment through a transmissive area or a perforated opening formed in the rollable display 430 in the second space 4201 of the second housing 420. According to an embodiment, the area of ​​the rollable display 430 facing the first camera module 405 may be formed as a transmissive area with a specified transmittance as a part of the display area for displaying content. According to an embodiment, the transmissive area may be formed to have a transmittance in the range of about 5% to about 20%. For example, the transmissive area of ​​the rollable display 430 may include an area having a lower pixel arrangement density and / or a wire density than the surrounding area. For example, the transmissive area may replace the above-mentioned opening. The first camera module 405 may include a camera, also referred to as an under-display camera (UDC), which is located below the display 430 and receives light through the transmissive area of ​​the display 430. In a certain embodiment, the first sensor module 404 may be disposed in an internal space of the electronic device 400 to perform its function without being visually exposed through the rollable display 430 .

[0095] The electronic device 400 may include a wireless communication circuit (eg, Figure 1 According to an embodiment, the electronic device 400 may include a frame antenna A provided by a conductive first side member 411 of the first housing 410. For example, the frame antenna A may include a conductive portion 427 provided on at least a portion of a second side surface 4112 and a third side surface 4113 of the first side member 411, and electrically separated by one or more segmenting portions 4271 and 4272 formed of a non-conductive material (e.g., a polymer). According to an embodiment, the electronic device 400 may include a side cover 4112a provided on the second side surface 4112 to cover at least a portion of at least one segmenting portion 4271. In a certain embodiment, the frame antenna A may be provided on at least one of the first side surface 4111, the second side surface 4112, and the third side surface 4113. In a certain embodiment, the frame antenna A may be provided on at least one of the fourth side surface 4211, the fifth side surface 4212, and the sixth side surface 4213 of the second housing 420.

[0096] According to an embodiment, switching from the slide-in state to the slide-out state or from the slide-out state to the slide-in state may be automatically performed. For example, the switching of the state may be performed by gear engagement between a sliding motor including a pinion gear disposed in the first space 4101 of the first housing 410 and a rack gear disposed in the second space 4201 of the second housing 420 and engaged with the pinion gear. For example, when a trigger operation for switching the state is detected, a processor (e.g., Figure 1 The processor 120 in the rollable display 430 may drive a slide motor provided inside the electronic device 400. According to an embodiment, the trigger operation may include selecting (eg, touching) an object displayed on the rollable display 430 or manipulating a physical button (eg, a key button) included in the electronic device 400.

[0097] Based on the posture of the electronic device, the display mode of the electronic device can be determined as a vertical mode (or portrait mode) or a horizontal mode (or landscape mode). Figure 1 In the embodiment, the sensor module 176 may include a sensor (e.g., an acceleration sensor or a gyroscope sensor) that identifies the relative position of the side in the housing structure of the electronic device 101 and generates data for identifying the movement and direction of the electronic device 101. The processor 120 may recognize the posture of the electronic device based on the data received from the sensor, and determine the display mode as a landscape mode or a portrait mode based on the recognized posture. The processor 120 may display visual information on the display based on the determined display mode.

[0098] The processor 120 may classify the display area of ​​the display into one or more areas based on the state of the electronic device. The size (area) of the screen to be displayed in the display area (e.g., an application execution screen or a background image) does not change depending on the state change, and the width and height of the screen may be reversed depending on the posture change. For example, if the size of the screen in the portrait mode is M (width) * N (height), the size of the screen in the landscape mode may be N (width) * M (height).

[0099] According to an embodiment, in an electronic device having an outward folding type foldable shell structure, if the electronic device is identified as being in a folded state, the processor 120 may divide the display area into two display areas facing opposite directions. In an electronic device having an outward folding type foldable shell structure, if it is identified that the electronic device is in a partially folded state and the angle between the first shell and the second shell falls within a specified first angle range (e.g., between about 90 degrees and 120 degrees), the processor 120 may divide the display area into two display areas. In an electronic device having an outward folding type foldable shell structure, if it is identified that the electronic device is in an unfolded state or a partially folded state, wherein the angle between the first shell and the second shell falls within a specified second angle range (e.g., between about 120 degrees and 179 degrees), the processor 120 may determine the display area as one without dividing it.

[0100] According to an embodiment, in an electronic device having a foldable housing structure of an inward folding type, if it is recognized that the electronic device is in a partially folded state and the angle between the first housing and the second housing falls within a specified first angle range (e.g., between about 90 degrees and 120 degrees), the processor 120 may divide the display area into two display areas. For example, if the electronic device is recognized as being in a partially folded state Figure 3e In the state shown, the processor 120 can control the display to display a background image in one of the first display area 311 and the second display area 312, and display an application execution screen in the other. In an electronic device having a foldable shell structure of an inward folding type, if it is identified that the electronic device is in an unfolded state or a partially folded state, wherein the angle between the first shell and the second shell falls within a specified second angle range (e.g., between about 120 degrees and 179 degrees), the processor 120 can determine the display area as one without dividing it. The processor 120 can display the background image in an area identified as a blank area in the first display area. The processor 120 can display the background image in an area identified as a blank area in the second display area. If the display area is determined to be one without dividing it, the processor 120 can display the background image in an area identified as a blank area in the entire display area.

[0101] According to an embodiment, in an electronic device having a bar-type housing structure, the processor 120 may determine the display area as one without dividing it. The processor 120 may display a background image in an area identified as a blank area among the entire display area.

[0102] According to an embodiment, in an electronic device having a slidable housing structure, the processor 120 may determine the display area as one without dividing it. The processor 120 may display a background image in an area identified as a blank area in the display area exposed to the outside.

[0103] Based on the application executed by the processor 120, a corresponding execution screen may be displayed on a portion of the display. The processor 120 may configure at least a portion of a blank area of ​​the entire display area of ​​the display that is not covered by the application execution screen and does not include an area where the application execution screen is displayed (hereinafter, the application display area) as a display area for displaying a background image (hereinafter, the background image display area). The position and / or size of the application execution screen may change on the display, for example, depending on user input (e.g., a touch gesture), and therefore, the background image display area may need to be reconfigured. In this document, reconfiguration of the background image display area may be defined as changing the position of the background image display area and / or adjusting (reducing or increasing) its size on the display.

[0104] Based at least on the occurrence of a triggering event that causes reconfiguration of the background image display area, the electronic device may reconfigure the background image display area and display the background image in the reconfigured background image display area.

[0105] According to an embodiment, in an electronic device having a bar-type housing structure, a trigger event may include a change in a display mode discovered as a result of monitoring the posture of the electronic device (e.g., a change in the display mode from a horizontal mode to a vertical mode, or vice versa). The trigger event may include a visual change in an application execution screen recognized as a result of monitoring the state of the application (e.g., the application execution screen is called to the home screen, the display of the application execution screen is terminated, or the position of the application execution screen is changed on the home screen).

[0106] According to an embodiment, in an electronic device having a foldable housing structure or a slidable housing structure, a trigger event may include a change in a display mode. A trigger event may include a visual change in an application execution screen. A trigger event may include a state change recognized as a result of monitoring the state of the electronic device.

[0107] As the background image display area is reconfigured, reconstruction (in other words, editing or modification) of the background image may be required. For example, reconstruction may be to reduce the size of the background image (e.g., a tile-type image) while increasing the number of images to fill the background image display area. According to an embodiment, reconstruction may be to process the image so that the main object of the background image (e.g., the object closest to the center of the image or the object with the largest size among the objects present in the background image, which is identified as a result of image recognition of the background image) is located at the center of the background image display area. According to an embodiment, reconstruction may reduce the size of the background image (e.g., a horizontal image) while maintaining its aspect ratio. The processor 120 may display the reconstructed background image in the background image display area.

[0108] Figure 5 is a block diagram of an electronic device 500 according to an embodiment. Figure 6 1 is a diagram showing connections between modules 541 to 548 configured in the electronic device 500 .

[0109] refer to Figure 5 and Figure 6 , the electronic device 500 may include a posture sensor 510, a state sensor 520, a display 530, a posture monitoring module 541, a state monitoring module 542, an application monitoring module 543, a background image monitoring module 544, a feature extraction module 545, a background image display area reconfiguration module (hereinafter, referred to as a reconfiguration module) 546, a background image reconstruction module (hereinafter, referred to as a reconstruction module) 547, a background image service module 548, a memory 588 and a processor 599. The above components of the electronic device 500 may be operably or electrically connected to each other. Modules 541 to 548 may be implemented in software. For example, the background image service module 548 may be an application (e.g., Figure 1 The remaining modules 541 to 547 may be included in the middleware (e.g., Figure 1 Modules 541 to 548 may be stored as instructions in a non-volatile memory (eg, Figure 1 134) and loaded into a volatile memory (e.g., Figure 1 volatile memory 132) and then by processor 599 (e.g., Figure 1 At least one of modules 541 to 548 may be executed by a processor dedicated to background image service (eg, auxiliary processor 123). If the electronic device 500 is implemented to have a bar-type housing structure, the state sensor 520 and the state monitoring module 542 may be omitted from the electronic device 500.

[0110] The posture sensor 510 may be configured to include a gyroscope sensor and / or an acceleration sensor, and may identify the relative position of the side in the housing structure of the electronic device 500, and generate data for identifying the movement and direction of the electronic device 500. Based on the data received from the posture sensor 510, the processor 120 may recognize the posture of the electronic device 500, and determine the display mode as a horizontal mode or a vertical mode based on the recognized posture. The processor 120 may display visual information on the display based on the determined display mode. For example, a first axis (e.g., Figure 2 The direction facing the x-axis in the figure can be configured to be the same as the direction in which the first side of the housing structure of the electronic device 500 extends. The second axis of the posture sensor 510 (eg, Figure 2 The direction facing the y-axis in the image may be configured to be the same as the direction in which the second side of the housing structure, which is perpendicular to the first side and relatively longer, extends. If the first axis direction of the posture sensor 510 is identified as being the same as or opposite to the direction of gravity, the processor 120 may determine that the display mode is the horizontal mode, and

[0111] The visual information corresponding to the horizontal mode is configured. If the second axis direction of the posture sensor 510 is recognized to be the same as or opposite to the gravity direction, the processor 120 may determine the display mode as the vertical mode and configure the visual information corresponding to the vertical mode.

[0112] The state sensor 520 may generate data for identifying the state of the electronic device 500. In an embodiment, if the electronic device 500 has a foldable housing structure, the state sensor 520 may include a sensor (e.g., an encoder or a Hall sensor) attached to a hinge assembly (e.g., the hinge assembly 340 in FIG. 3) and generating and outputting data corresponding to an angle. According to an embodiment, the state sensor 520 may include a motion sensor (e.g., an acceleration sensor and / or a gyroscope sensor) disposed in the internal space of the housing of the electronic device 500. For example, the state sensor 520 may include a first motion sensor disposed in a first housing (e.g., the first housing 310 in FIG. 3) and generating data corresponding to a posture (position) and / or motion (e.g., angular velocity and / or acceleration) of the first housing, and a second motion sensor disposed in a second housing (e.g., the second housing 320 in FIG. 3) and generating data corresponding to a posture and / or motion of the second housing. The state sensor 520 may be configured as a combination of a Hall sensor and an acceleration sensor. In a certain embodiment, one of the two motion sensors may be used as the posture sensor 510. The processor 599 may recognize the state of the electronic device 500 using the data received from the state sensor 520. For example, the processor 599 may calculate the angle formed between the first housing 310 and the second housing 320 using the data received from the state sensor 520, and recognize the state of the electronic device 500 based on the data obtained as a result of the calculation.

[0113] In an embodiment, if the electronic device 500 has a slidable housing structure, the state sensor 520 may include a sensor (eg, an encoder or a Hall sensor) attached to a sliding member (eg, a reference Figure 4c The state sensor 520 may include a gear (e.g., a pinion) that moves the second housing 420 of the display 530, and when the gear rotates by the force transmitted from the slide motor or the force transmitted from the user through the slide, data corresponding to the rotation angle is generated and output. According to an embodiment, the state sensor 520 may include a sensor (e.g., a pressure sensor) that is provided on a bendable portion of the display 530 and generates data corresponding to the curvature of the portion. Based on the data received from the state sensor 520, the processor 599 may recognize the state of the electronic device 500 as a slide-in state or a slide-out state.

[0114] The posture monitoring module 541 can monitor the posture of the electronic device 500 using the data generated by the posture sensor 510, and provide the monitoring result (posture change) to the reconfiguration module 546 and the background image service module 548. For example, the posture monitoring module 541 can provide a posture change event as the monitoring result to the reconfiguration module 546 and the background image service module 548, the posture change event indicating a change from a first posture corresponding to the horizontal mode to a second posture corresponding to the vertical mode, or vice versa.

[0115] The state monitoring module 542 may monitor the state of the electronic device 500 using data generated by the state sensor 520, and provide the monitoring result to the reconfiguration module 546 and the background image service module 548. According to an embodiment, the state monitoring module 542 may provide the reconfiguration module 546 and the background image service module 548 with a state change event indicating a change from a folded state to an intermediate state, a change from an intermediate state to an unfolded state, or vice versa as a monitoring result. The state monitoring module 542 may provide information indicating an angle between two shells in a foldable shell structure together with the event to the reconfiguration module 546 and the background image service module 548. According to an embodiment, the state monitoring module 542 may provide the reconfiguration module 546 and the background image service module 548 with a state change event indicating a change from a slide-in state to a slide-out state, or vice versa.

[0116] The application monitoring module 543 can monitor the state of the application stored in the memory 588, and provide the monitoring result to the reconfiguration module 546 and the background image service module 548. Here, the monitoring target may include an application that can provide visual information to the user or provide an execution screen (user interface screen) for interaction with the user. The monitoring target may include a preloaded application or a third-party application that can be downloaded from the server 108. The application monitoring module 543 may provide an application change event as a monitoring result to the reconfiguration module 546 and the background image service module 548, and the application change event is an event such as calling the application execution screen to the main screen, ending the display of the application execution screen, or changing the position of the application display area on the main screen. The application monitoring module 543 may provide the identification information (e.g., process ID) of the corresponding application together with the event to the reconfiguration module 546 and the background image service module 548. The application monitoring module 543 may provide the position information (e.g., the coordinates of the upper left corner and the width and height of the display area) of the application display area to display the application execution screen together with the event to the reconfiguration module 546 and the background image service module 548.

[0117] The background image monitoring module 544 may monitor whether a background image change event occurs to display a second background image to replace the first background image being displayed on the display. If a background image change event occurs, the background image monitoring module 544 may notify the feature extraction module 545 and the background image service module 548 of the occurrence of the background image change event. If the background image change event is generated by the background image service module 548, the background image monitoring module 544 may ignore the occurrence of the background image change event without notifying the feature extraction module 545 and the background image service module 548. For example, the fact that the first background image and the second background image are stored in a folder may indicate that the background image change event is generated by the background image service module 548. Therefore, if the first background image and the second background image are stored in the same folder, the background image monitoring module 544 may not react to the occurrence of the background image change event. If the background image change event is generated by another module (e.g., an operating system), the background image monitoring module 544 may react to the occurrence of the background image change event and notify the feature extraction module 545 and the background image service module 548 of the background image change event. The background image monitoring module 544 may provide information about the first background image and information about the second background image to the feature extraction module 545 and the background image service module 548. For example, the background image information provided to the feature extraction module 545 and the background image service module 548 may include a file name, a folder name, a folder path, or unique identification information (e.g., a hash value) of the corresponding image.

[0118] In response to receiving a background image change event from the background image monitoring module 544, the feature extraction module 545 can extract information representing the features of the corresponding image from the background image (e.g., the second background image), and store the extracted feature information in the first memory area 601 allocated for feature information storage in the memory 588. If the background image needs to be reconstructed, the background image reconstruction module 547 can identify the corresponding feature information from the first memory area 601. The feature information extracted by the feature extraction module 545 may include information about the type of the corresponding image (e.g., tile, landscape, or portrait), identification information for identifying the main object from the objects present in the image, location information indicating the location of the main object in the corresponding image (e.g., the coordinates of the upper left corner of the corresponding main object, and the width and height of the main object), or information about whether to allow arbitrary reconstruction of the corresponding image. Whether reconstruction is allowed is determined by the business operator who provides or generates the corresponding image, and can be defined in the metadata of the corresponding image. The above-mentioned feature information can be extracted from the metadata of the corresponding image file. The identification information can be extracted using an artificial intelligence model. For example, the artificial intelligence model can be machine-learned to output feature information as a result value of a given input value (image). The feature extraction module 545 may input the background image as an input value to the artificial intelligence model. The feature extraction module 545 may obtain feature information from the result value output by the artificial intelligence model.

[0119] The reconfiguration module 546 may reconfigure the background image display area based on the monitoring results provided from the monitoring modules 541, 542, and 543, and store the size and position information about the reconfigured background image display area in the second memory area 602 allocated for storing the position information of the background image display area in the memory 588. If the screen of the electronic device 500 needs to be reconstructed, the background image service module 548 may identify the corresponding position information from the second memory area 602.

[0120] According to an embodiment, the reconfiguration module 546 may receive an event of calling the application execution screen to the main screen while displaying the background image through the entire display area configured as the background image display area of ​​the display 530 from the application monitoring module 543. The reconfiguration module 546 may reduce the background image display area so as not to overlap with the application execution screen called to the main screen. The reconfiguration module 546 may provide the position information of the reduced background image display area to the background image service module 548.

[0121] According to an embodiment, the reconfiguration module 546 may receive an event from the application monitoring module 543 to terminate the display of the application execution screen so as not to overlap each other while the background image and the application execution screen are being displayed. In response to the termination of the display of the application execution screen, the reconfiguration module 546 may enlarge the background image display area to, for example, the entire display area. The reconfiguration module 546 may provide the position information of the enlarged background image display area to the background image service module 548.

[0122] According to an embodiment, the reconfiguration module 546 may receive an event from the application monitoring module 543 that changes the position of the application display area so as not to overlap each other while the background image and the application execution screen are being displayed. The application execution screen may be displayed in the application display area whose position is changed. In response to the change in the position of the application execution screen, the reconfiguration module 546 may reconfigure the background image display area (e.g., reduce the size or change the position to be displayed) so that it does not overlap with the application execution screen. The reconfiguration module 546 may provide the position information of the reconfigured background image display area to the background image service module 548.

[0123] According to an embodiment, the reconfiguration module 546 may receive an event from the posture monitoring module 541 indicating a change from a first posture corresponding to a horizontal mode to a second posture corresponding to a vertical mode, or vice versa, while the background image and the application execution screen are being displayed so as not to overlap each other. In response to the change in posture, the reconfiguration module 546 may reconfigure the background image display area (e.g., reduce the size or change the position to be displayed) so that it does not overlap with the application execution screen. The reconfiguration module 546 may provide the position information of the reconfigured background image display area to the background image service module 548.

[0124] According to an embodiment, the reconfiguration module 546 may receive an event indicating a state change from the state monitoring module 542 while the background image and the application execution screen are being displayed so as not to overlap each other. In response to the state change, the reconfiguration module 546 may reconfigure the background image display area (e.g., reduce the size or change the position to be displayed) so that it does not overlap with the application execution screen. The reconfiguration module 546 may provide the position information of the reconfigured background image display area to the background image service module 548.

[0125] The reconstruction module 547 may reconstruct the background image to be displayed in the background image display area reconfigured by the reconfiguration module 546 based on the feature information received from the feature extraction module 545. The reconstruction module 547 may provide the reconstructed background image to the background image service module 548.

[0126] According to an embodiment, the reconstruction module 547 may reconstruct the background image (eg, a tile type image) by reducing the size of the background image while increasing the number of the background images so as to fill the background image display area.

[0127] According to an embodiment, the reconstruction module 547 can reconstruct the background image by processing the image so that the main object of the background image (for example, the object closest to the center of the image or the object with the largest size among the objects present in the background image, which is identified as a result of image recognition of the background image) is located in the center of the background image display area.

[0128] According to an embodiment, the reconstruction module 547 may reconstruct the background image by reducing the size of the background image (eg, landscape image) to fit the background image display area while maintaining the aspect ratio of the background image display area.

[0129] The background image service module 548 may display the background image reconstructed by the reconstruction module 547 in the background image display area reconfigured by the reconfiguration module 546 .

[0130] Figure 7 is a flowchart showing an operation for providing a background image service to a user according to an embodiment. The processor 599 may execute the above modules 541 to 548 to perform Figure 7 Operations in . Figure 8a and Figure 8b is a diagram illustrating an operation for reconstructing a tile-type background image. Figure 9a and 9b is a diagram illustrating an operation for reconstructing an object-type background image. Fig.10a and Fig.10b is a diagram showing an operation for reconstructing a landscape-type background image. Fig.11 is a diagram showing a screen layer structure according to an embodiment.

[0131] In operation 710, the processor 599 may identify whether a condition is satisfied for reconstructing the screen of the electronic device 500 being displayed on the display 530. The reason for identifying whether the screen reconstruction condition is satisfied is that if screen reconstruction (e.g., background image display area reconstruction and / or background image reconstruction) is frequently performed, the performance of the electronic device 500 may be degraded and unnecessary power consumption may be caused.

[0132] According to an embodiment, if no additional gesture change event occurs within a specified time (eg, several seconds) from the time when the gesture change event occurs by the gesture monitoring module 541 , the screen reconstruction condition may be considered to be satisfied.

[0133] According to an embodiment, if no additional state change event occurs within a specified time from the time when the state change event occurs in the state monitoring module 542 , it may be considered that the screen reconstruction condition is satisfied.

[0134] According to an embodiment, if a display end event (or a call event) does not occur within a specified time from the time when the application monitoring module 543 generates a call event that calls the application execution screen to the main screen (or a display end event that ends the display of the application execution screen), the screen reconstruction condition may be considered to be satisfied. If the display of the application execution screen is terminated within a specified time after the application execution screen is called to the main screen (or vice versa), the screen reconstruction condition may be considered not to be satisfied.

[0135] According to an embodiment, if no additional event (e.g., a call event, a display end event, or a position change event) occurs within a specified time from the time when the application monitoring module 543 changes the position change event of the application execution screen on the main screen, and if the ratio of the blank area to the activation area on the display 530 where visual information is being displayed is greater than or equal to a specified value, the screen reconstruction condition may be considered to be satisfied. If no additional event occurs within a specified time from the time when the position change event occurs and if the ratio of the blank area to the entire display area (activation area) calculated after the position change event is greater than the ratio of the blank area to the entire display area calculated before the position change event by a specified value or more, the screen reconstruction condition may be considered to be satisfied. Here, the display area (activation area) of the display 530 activated to display visual information may be the entire display area of ​​the display 530 in the bar-type electronic device 500, may be changed depending on the degree of folding of the foldable housing in the foldable electronic device 500 (e.g., the entire display area in the unfolded state or one of the first display area and the second display area divided by the hinge assembly in the partially folded state), and may be the portion of the display area of ​​the display 530 in the slidable electronic device 500 that is exposed to the outside.

[0136] According to an embodiment, if no additional background image change event occurs from the time when the background image change event occurs by the background image monitoring module 544, it may be considered that the screen reconstruction condition is satisfied.

[0137] If the screen reconstruction condition is satisfied, the processor 599 may reconfigure the background image display area based on the result of monitoring the posture, state, and application in operation 715. If the posture, state, and application have not changed (e.g., if there is a change only in the background image) as a result of monitoring, the processor 599 may skip operation 715 and perform operation 720.

[0138] In operation 720, the processor 599 may collect information indicating the size and position of an area configured as a background image display area in the active area of ​​the display 530 and information indicating features of a background image to be displayed in the configured background image display area, which are the basis for screen reconstruction.

[0139] According to an embodiment, the processor 599 may obtain the size and position information of the display area (e.g., at least a portion of the area configured as a blank area) capable of fully displaying the background in the activation area of ​​the display 530 by monitoring the result of the application. The processor 599 may store the size and position information of the background image display area obtained by monitoring the result of the application in, for example, the second memory area 602. If the screen reconstruction condition is met, the processor 599 may obtain (collect) the size and position information of the background image display area from the second memory area 602.

[0140] According to an embodiment, the processor 599 may obtain feature information from the background image, and store the obtained feature information together with the corresponding background image and its identification information (e.g., hash value) in, for example, the first memory area 601. Based on the occurrence of an event indicating an application change, the processor 599 may obtain feature information of the first background image being displayed on the display 530 from the first memory area 601. According to an embodiment, the processor 599 may obtain feature information of the second background image from the first memory area 601 based on the occurrence of an event that triggers the background image to change from the first background image to the second background image. According to an embodiment, the processor 599 may also obtain feature information of the first background image being displayed on the display 530 from the first memory area 601 based on the occurrence of a posture change event or a state change event.

[0141] In operation 730, the processor 599 may determine whether to allow reconstruction of the background image based on the collected feature information. If it is recognized that the collected feature information includes information indicating that reconstruction is allowed, the processor 599 may perform operation 750. If it is recognized that the collected feature information includes information indicating that reconstruction is not allowed, the processor 599 may select another background image that allows reconstruction from, for example, the first memory area 601, collect feature information of the selected background image from the first memory area 601, and then perform operation 750.

[0142] In operation 750, the processor 599 may reconstruct the background image based on the feature information collected in operation 720 or operation 740. First, the processor 599 may identify the type of the background image from the feature information. The processor 599 may reconstruct the background image based on the identified type. An embodiment for type-based background image reconstruction operation will be described with reference to FIGS. 8 to 10.

[0143] refer to Figure 8a and Figure 8b , the processor 599 may display a first background image 811 of a tile type in a first background image display area 821 (e.g., the entire display area of ​​the display 530). When an event occurs to call the application execution screen to the display 530, the processor 599 may configure an application display area 830 in the display area of ​​the display 530. The processor 599 may configure a second background image display area 822 that is smaller (reduced in area) than the first background image display area 821 so as not to overlap with the application display area 830. The processor 599 may generate a second background image 812 by reducing the size of the first background image 811 but increasing the number of images so that they fill up the second background image display area 822.

[0144] Return to reference Figure 8a and Figure 8b If an event that terminates the execution of the application occurs while the application execution screen 840 is being displayed in the application display area 830 and while the second background image 812 is being displayed in the second background image display area 822, the processor 599 may reconfigure the area in which the background image is to be displayed into the first background image display area 811 and reconstruct the background image to be displayed in the first background image display area 811 as the first background image 811.

[0145] refer to Figure 9a and Figure 9b , the processor 599 may display a first background image 911 of an object type in a first background image display area 921 (e.g., the entire display area of ​​the display 530). If an event occurs to call the application execution screen to the display 530, the processor 599 may configure an application display area 930 in the display area of ​​the display 530. The processor 599 may configure a second background image display area 922 that is smaller than the first background image display area 921 so as not to overlap with the application display area 930. The processor 599 may process the first background image 911 so that a main object 911a of the first background image 911 (e.g., an object closest to the center of the image or an object with the largest size among the objects present in the first background image 911, which is recognized as a result of image recognition of the first background image 911) is located at the center of the second background image display area 922, thereby generating a second background image 912.

[0146] Return to reference Figure 9a and Figure 9bIf an event that terminates the execution of the application occurs while the application execution screen 940 is being displayed in the application display area 930 and while the second background image 912 is being displayed in the second background image display area 922, the processor 599 may reconfigure the area in which the background image is to be displayed into the first background image display area 911 and reconstruct the background image to be displayed in the first background image display area 911 into the first background image 911.

[0147] refer to Fig.10a and Fig.10b , the processor 599 may display a landscape-type first background image 1011 in a first background image display area 1021 (e.g., the entire display area of ​​the display 530). If an event occurs to call the application execution screen to the display 530, the processor 599 may configure an application display area 1030 in the display area of ​​the display 530. The processor 599 may configure a second background image display area 1022 that is smaller than the first background image display area 1021 so as not to overlap with the application display area 1030. The processor 599 may reduce the first background image 1011 to conform to the width or height of the second background image display area 1022 while maintaining its aspect ratio, thereby generating the second background image 1012. For example, the width and height of the first background image 1011 may be W1 and H1, respectively. The processor 599 may reduce the width and height from W1 and H1 to W2 and H2 while maintaining the aspect ratio, and reduce the width to conform to the width W3 of the second background image display area 1022.

[0148] Return to reference Fig.10a and Fig.10b If an event that terminates the execution of the application occurs while the application execution screen 1040 is being displayed in the application display area 1030 and the second background image 1012 is being displayed in the second background image display area 1022, the processor 599 can reconfigure the area where the background image is to be displayed into the first background image display area 1021, and reconstruct the background image to be displayed in the first background image display area 1021 as the first background image 1011.

[0149] In operation 760, the processor 599 may reconstruct the screen using the reconstructed background image, and display the reconstructed screen on the activated display area (activation area) of the display 530 to display visual information. Here, the activation area where the reconstructed screen is to be displayed may be the entire display area of ​​the display 530 in the bar-type electronic device 500. It may change depending on the degree of folding of the foldable shell in the foldable electronic device 500. For example, if the electronic device 500 is in an unfolded state, the entire display area of ​​the display 530 may be configured as an activation area. If the electronic device 500 is in a partially folded state, one of the first display area and the second display area divided by the hinge assembly may be configured as an activation area. According to an embodiment, even if the electronic device 500 is in a partially folded state, the entire display area of ​​the display 530 may be configured as an activation area. If the electronic device 500 is configured as a slidable type, a portion of the display area of ​​the display 530 exposed to the outside may be configured as an activation area. Reference will be made to Fig.11 An embodiment of an operation of displaying a reconstruction screen in an active area is described.

[0150] refer to Fig.11 , the processor 599 may generate an image of a specified monochrome (e.g., white) filling the entire activation area as a first layer image 1110. The processor 599 may generate a second layer image 1120 filling the entire activation area. The processor 599 may generate the second layer image 1120 having a representative color (e.g., a color having the highest proportion among the colors constituting the background image) from the background image reconstructed in operation 750. Alternatively, the processor 599 may generate the second layer image 1120 by processing the background image reconstructed in operation 750 to appear blurred (so-called blur processing). The processor 599 may synthesize the layer images 1110, 1120, and 1140 by superimposing the second layer image 1120 on the first layer image 1110 and superimposing the third layer image 1140 as the background image reconstructed in operation 750 on an area 1130 corresponding to the background image display area in the second layer image 1120, thereby generating a background screen 1100 to be displayed in the activation area. The processor 110 may display a background screen 1100 including a reconstructed background image on the active area of ​​the display 530. The processor 110 may display the application execution screen as a foreground screen of the background screen 1100. For example, the processor 110 may display the application execution screen on the second layer image 1120 so as not to overlap with the third layer image 1140 as the background image.

[0151] Fig.12 is a diagram illustrating connections among the application monitoring module 543, the background image display area reconfiguration module 546, and the background image service module 548 according to an embodiment.

[0152] The reconfiguration module 546 can receive application change events from the application monitoring module 543 as a result of monitoring performed by the application monitoring module 543, such as a call event that calls the application execution screen to the activation area of ​​the display 530, an end event that terminates the display of the application execution screen in the activation area of ​​the display 530, or a position change event that changes the position of the application execution screen in the activation area.

[0153] The reconfiguration module 546 may manage the second memory area 602 based on the type of application change event received from the application monitoring module 543. For example, when a call event is received, the reconfiguration module 546 may store identification information (e.g., process ID) of the application corresponding to the called application execution screen in the second memory area 602. In addition, when a call event is received, the reconfiguration module 546 may configure the background image display area so as not to overlap with the called application execution screen, and store the size and position information of the configured background image display area in the second memory area 602. When a position change event is received, the reconfiguration module 546 may reconfigure the background image display area so as not to overlap with the application execution screen whose position is changed, and update the existing size and position information stored in the second memory area 602 with the size and position information of the reconfigured background image display area. When an end event is received, the reconfiguration module 546 may delete the identification information of the corresponding application from the second memory area 602. In addition, when an end event is received, the reconfiguration module 546 can reconfigure the background image display area to the entire activation area, and update the existing size and position information stored in the second memory area 602 with the size and position information of the reconfigured background image display area.

[0154] If the background image service module 548 requests the size and position information of the background image display area for screen reconstruction, the reconstruction module 546 may obtain the corresponding information from the second memory area 602 and provide it to the background image service module 548 .

[0155] Fig.13 is a flowchart showing the operation of managing a database related to a background image display area according to an embodiment. The processor 599 may execute the above modules 543, 546 and 548 to perform Fig.13 You can Figure 7 Before executing operation 710 Fig.13 Operations in .

[0156] In operation 1310, the processor 599 may recognize that a change related to the state of the application has occurred. For example, the processor 599 may recognize that the application execution screen has been called to the display 530, the display of the application execution screen has ended, or the position of the application execution screen has changed on the display 530.

[0157] In operation 1320, the processor 599 may manage the corresponding database (e.g., the second memory area 602) based on the type of change identified (e.g., call, display end, or position change). If the type of change is display end, the processor 599 may delete the identification information of the corresponding application from the database. If the type of change is call, the processor 599 may store the size of the application execution screen, the position information about the display area of ​​the display 530, and the identification information of the corresponding application in the database. If the type of change is position change, the processor 599 may update the existing position information stored in the database with the changed position information about the display area of ​​the display 530.

[0158] Fig.14 is a diagram showing connections among a gesture monitoring module 541, a state monitoring module 542, a background image display area reconfiguration module 546, and a background image service module 548 according to an embodiment.

[0159] The reconfiguration module 546 may receive an event from the posture monitoring module 541 as a monitoring result performed by the posture monitoring module 541, the event indicating a change from a first posture corresponding to the horizontal mode to a second posture corresponding to the vertical mode, or vice versa. Here, the posture change event may be generated by the operating system 1401 and sent to the reconfiguration module 546 through the posture monitoring module 541.

[0160] The reconfiguration module 546 may receive a state change event from the state monitoring module 542 as a monitoring result performed by the state monitoring module 542. According to an embodiment, the reconfiguration module 546 may receive a state change event from the state monitoring module 542, the state change event indicating a change from a folded state to an intermediate state, from an intermediate state to an unfolded state, or vice versa. In addition, the reconfiguration module 546 may receive information indicating an angle between two shells in a foldable shell structure from the state monitoring module 542. According to an embodiment, the reconfiguration module 546 may receive a state change event from the state monitoring module 542, the state change event indicating a change from a slide-in state to a slide-out state, or vice versa. Here, the state change event and the angle information may be generated by the operating system 1401 and sent to the reconfiguration module 546 via the state monitoring module 542.

[0161] The reconfiguration module 546 can manage the second memory area 602 based on the events and information received from the posture monitoring module 541 and the state monitoring module 542. For example, when a state change event is received, the reconfiguration module 546 can update the existing state information stored in the second memory area 602 with information indicating the state after the change. The reconfiguration module 546 can update the existing angle information stored in the second memory area 602 with the angle information received from the state monitoring module 542.

[0162] The reconfiguration module 546 may classify the display area of ​​the display 530 into one or more areas based on the updated state and angle information in the second memory area 602. The reconfiguration module 546 may configure at least a portion of the display area identified as a blank area as a background image display area, and store (newly store or update) the configuration information (size and position information) in the second memory area 602.

[0163] In an electronic device 500 having a foldable shell structure of an outward folding type, according to an embodiment, if the electronic device 500 is identified as being in a folded state, the reconfiguration module 546 may divide the display area into two display areas facing opposite directions. If it is identified that the electronic device 500 is in a partially folded state and the angle between the first shell and the second shell falls within a specified first angle range (e.g., between about 90 degrees and 120 degrees), the reconfiguration module 546 may divide the display area into two display areas. If it is identified that the electronic device 500 is in an unfolded state or a partially folded state, wherein the angle between the first shell and the second shell falls within a specified second angle range (e.g., between about 120 degrees and 179 degrees), the reconfiguration module 546 may determine the display area as one without dividing it.

[0164] In the electronic device 500 having a foldable housing structure of an inward folding type, according to an embodiment, if it is recognized that the electronic device 500 is in a partially folded state and the angle between the first housing and the second housing falls within a specified first angle range (e.g., between about 90 degrees and 120 degrees), the reconfiguration module 546 may divide the display area into two display areas. For example, if the electronic device 500 is recognized as being in a partially folded state Figure 3eThe state shown, the reconfiguration module 546 can display the background image in one of the first display area 311 and the second display area 312, and display the application execution screen in the other. If it is identified that the electronic device 500 is in an expanded state or a partially folded state, wherein the angle between the first shell and the second shell falls within a specified second angle range (for example, between about 120 degrees and 179 degrees), the reconfiguration module 546 can determine the display area as one without dividing it. The reconfiguration module 546 can configure the area identified as a blank area in the first display area as a background image display area. The reconfiguration module 546 can configure the area identified as a blank area in the second display area as a background image display area. If the display area is determined to be one without dividing it, the processor 120 can configure at least a portion of the area identified as a blank area in the entire display area as a background image display area.

[0165] In the electronic device 500 having a strip-type housing structure, according to an embodiment, the reconfiguration module 546 may determine the display area as one without dividing it. The processor 120 may configure at least a portion of the area identified as a blank area in the entire display area as a background image display area.

[0166] In the electronic device 500 with a slidable housing structure, according to an embodiment, the reconfiguration module 546 can determine the display area as one without dividing it. The reconfiguration module 546 can configure at least a portion of the area identified as a blank area in the display area exposed to the outside as a background image display area.

[0167] If the background image service module 548 requests information about the number of display areas and the size and position of the background image display area for screen reconstruction, the reconstruction module 546 can obtain the corresponding information from the second memory area 602 and provide it to the background image service module 548.

[0168] Fig.15 is a flowchart showing the operation of managing a database related to a background image display area according to an embodiment. The processor 599 may execute the above modules 541, 542, 546 and 548 to perform Fig.15 You can Figure 7 Before executing operation 710 Fig.15 Operations in .

[0169] At operation 1510, the processor 599 may recognize that a change has occurred with respect to the posture and / or state of the electronic device 500. Here, the posture change and the state change have been described above (eg, see Fig.14), so the description will be omitted.

[0170] In operation 1520 , the processor 599 may store information related to the change of posture and / or state (eg, posture information, state information, and angle information) in a database (eg, the second memory area 602 ).

[0171] In operation 1530, the processor 599 may classify the display area of ​​the display 530 into one or more areas based on the information stored in the database. Fig.14 ), the display area can be classified into one or two areas depending on the type of shell structure applied to the electronic device 500.

[0172] At operation 1540 , the processor 599 may configure at least a portion of the area identified as the blank area in the classified display area as a background image display area, and store (newly store or update) the configuration information (size and position information) in the second memory area 602 .

[0173] Fig.16 is a diagram showing connections among a background image monitoring module 544, a feature extraction module 545, a background image reconstruction module 547, and a background image service module 548 according to an embodiment.

[0174] The feature extraction module 545 may receive a background image change event as a monitoring result performed by the background image monitoring module 544 from the background image monitoring module 544 to display a second background image by replacing the first background image being displayed on the display 530. The background image change event may be generated by the operating system 1601 and sent to the feature extraction module 545 through the background image monitoring module 544.

[0175] In response to receiving the background image change event, the feature extraction module 545 can obtain the identification information of the second background image. For example, the feature extraction module 545 can calculate the hash value of the second background image as the unique identification information of the second background image. The feature extraction module 545 can identify whether the unique identification information (hash value) is stored in the first memory area 601, and if there is unique identification information matching it as a result of the identification, the event reception is ignored without responding. If there is no matching unique identification information as a result of the identification, the feature extraction module 545 can extract feature information from the second background image and store the extracted feature information together with the second background image and its unique identification information in the first memory area 601. The feature information stored in the first memory area 601 may include information indicating whether arbitrary reconstruction of the corresponding background image is allowed.

[0176] If the reconstruction module 547 requests the background image and its feature information to reconstruct the background image, the feature extraction module 545 may obtain the background image and its feature information from the first memory area 601 and provide them to the background image reconstruction module 547. The reconstruction module 547 may reconstruct the background image to be displayed in the background image display area reconfigured by the reconfiguration module 546. The reconstruction module 547 may provide the reconstructed background image to the background image service module 548.

[0177] Fig.17 is a flowchart showing the operation of managing a database related to extracting feature information of a background image according to an embodiment. The processor 599 may execute the above modules 544, 545, 547 and 548 to perform Fig.17 You can Figure 7 Before executing operation 710 Fig.17 Operations in .

[0178] In operation 1710, the processor 599 may recognize the occurrence of an event requesting a change from a first background image being displayed on the display 530 to a second background image. For example, the background image change event may occur whenever a predetermined period of time passes or whenever the display 530 is turned off and then on.

[0179] In operation 1720, the processor 599 may obtain unique identification information of the second background image in response to the background image change request. For example, the processor 599 may calculate a hash value (unique identification information) of the second background image.

[0180] In operation 1730 , the processor 599 may recognize that the obtained unique identification information is not stored in the database (eg, the first memory area 601 ).

[0181] In operation 1740, the processor 599 may extract feature information from the second background image and store the extracted feature information together with the second background image and its unique identification information in a database.

[0182] Fig.18 is a flowchart illustrating an operation for providing a background image service according to an embodiment.

[0183] In operation 1810 , the processor 599 may display a first background image in a first background image display area configured to display a background image in a display area activated to display visual information on the display 530 .

[0184] In operation 1820, the processor 599 may monitor whether the posture of the electronic device 500 is changed from a first posture corresponding to the portrait mode to a second posture corresponding to the landscape mode or from the second posture to the first posture based on the data received from the posture sensor 510. In addition, the processor 599 may monitor whether there is a visual change on the application execution screen in the activated display area.

[0185] In operation 1830, based on recognizing a change in the posture of the electronic device 500 or a visual change in the application execution screen, the processor 599 may configure a second background image display area in the activated display area, the size of which is reduced from the first background image display area.

[0186] At operation 1840, the processor 599 may reconstruct the first background image into a second background image to be displayed in the second background image display area. The processor 599 may display the second background image in the second background image display area.

[0187] According to an embodiment, an electronic device (e.g., electronic device 500) may include: a housing of the electronic device; a display (e.g., display 530) disposed in the housing; a posture sensor (e.g., posture sensor 510) configured to generate data for recognizing a posture of the electronic device; a processor (e.g., processor 599) operably connected to the posture sensor and the display; and a memory (e.g., memory 588) operably connected to the processor and configured to store an application. The memory may store instructions that, when executed, cause the processor to perform operations. The instructions may cause the processor to: display a first background image in a first background image display area, the first background image display area being configured to display a background image in a display area activated to display visual information on the display. The instructions may cause the processor to: monitor whether the posture of the electronic device is changed from a first posture corresponding to a portrait mode to a second posture corresponding to a landscape mode or from the second posture to the first posture based on data received from the posture sensor. The instructions may cause the processor to: monitor whether there is a visual change in the execution screen of the application in the activated display area. The instructions may cause the processor to configure a second background image display area in the activated display area based on recognizing a change in the posture of the electronic device or a visual change in an application execution screen as a result of the monitoring, the second background image display area having a size reduced from that of the first background image display area. The instructions may cause the processor to reconstruct the first background image into a second background image to be displayed in the second background image display area. The instructions may cause the processor to display the second background image in the second background image display area.
