Description

Electronic device and method for aligning the positions of a camera and a flexible display using a pattern formed on the flexible display

[0001] The present disclosure relates to a wearable device and method for aligning the positions of a camera and a flexible display using a pattern formed on the flexible display.

[0002] The shape and / or size of electronic devices are diversifying. To enhance mobility, electronic devices with reduced size and / or volume are being designed. Electronic devices may include a display for visualizing information. As the number of functions supported by electronic devices increases, the size of the display may increase to visualize more information to the user and / or to support the execution of the functions. For example, electronic devices may be designed to be reduced in size and / or volume while maintaining or increasing the size of the display.

[0003] In one embodiment, an electronic device may include a housing including a second housing part configured to engage a first housing part so as to be movable between a collapsed position and an extended position, and a flexible display coupled to the first housing part and the second housing part. A size of an area of ​​the flexible display visible from a front surface of the housing may change as the housing is moved between the collapsed position and the extended position. The electronic device may include an actuator within the housing configured to move the second housing part relative to the first housing part, a camera within the housing positioned below an active area of ​​the flexible display, a memory for storing instructions, the memory including one or more storage media, and at least one processor within the housing including a processing circuit. The active area may include a first area having a first density of subpixels and a second area surrounding the first area and having a second density, the second area having a higher density than the first density. The rear surface of the flexible display, toward which the camera is directed, may include a pattern arranged along a boundary between the first region and the second region. The instructions, when individually and / or collectively executed by the at least one processor, may cause the electronic device to acquire an image through the camera in response to an input activating the camera. The instructions, when individually and / or collectively executed by the at least one processor, may cause the electronic device to identify whether a visual object corresponding to the pattern is included in the image.The instructions, when individually and / or collectively executed by the at least one processor, may cause the electronic device to control the actuator to align the camera with respect to the first area based on the image including the visual object.

[0004] In one embodiment, a method of an electronic device may include an operation of acquiring an image through a camera of the electronic device, the camera being positioned below an active area of ​​a flexible display of the electronic device, in response to an input activating the camera. The method may include an operation of identifying whether a visual object corresponding to a pattern formed on a rear surface of the flexible display toward which the camera is directed is included in the image. The method may include an operation of controlling the actuator to align the camera with respect to the flexible display based on the image including the visual object.

[0005] In one embodiment, an electronic device may include a housing, a flexible display at least partially exposed to the outside through one side of the housing, a camera within the housing positioned to face one side of the flexible display, an actuator for adjusting a position of the flexible display relative to the camera, a memory storing instructions, the memory including one or more storage media, and at least one processor including a processing circuit. The instructions, when individually and / or collectively executed by the at least one processor, may cause the electronic device to acquire an image using the camera. The instructions, when individually and / or collectively executed by the at least one processor, may cause the electronic device to identify whether a visual object associated with a boundary between a first region and a second region of the flexible display, the boundary being distinguished by a density of pixels, is included in the image. The instructions, when individually and / or collectively executed by the at least one processor, may cause the electronic device to control the actuator to adjust the position based on the image including the visual object.

[0006] In one embodiment, a method of an electronic device may include an operation of acquiring an image using a camera positioned to face one side of a flexible display of the electronic device. The method may include an operation of identifying whether a visual object associated with a boundary between a first region and a second region of the flexible display, the boundary being distinguished by a density of pixels, is included in the image. The method may include an operation of controlling the actuator to adjust the position based on the image including the visual object.

[0022] FIGS. 1A to 1E illustrate an embodiment of an electronic device (101) including a flexible display (110) and a camera (130). In one embodiment, the electronic device (101) may be referred to as a terminal (or user terminal) in terms of being owned by a user. The terminal may include, for example, a personal computer (PC) such as a laptop or desktop. The terminal may include, for example, a smartphone, a smartpad, and / or a tablet PC. The terminal may include a smart accessory such as a smartwatch and / or a head-mounted device (HMD). According to one embodiment, the housing (120) of the electronic device (101) may include an internal space in which one or more hardwares included in the electronic device (101) (e.g., one or more hardwares described above with reference to FIG. 2) are arranged. The above housing (120) can form the outer shape of the electronic device (101).

[0023] According to one embodiment, the electronic device (101) may have a deformable form factor. Deforming the electronic device (101) may mean that at least one of the dimensions, such as the width, height, and / or thickness, of the electronic device (101) is changed. At least one of the dimensions may be passively changed by an external force applied to the electronic device (101), and / or actively changed by one or more actuators included in the electronic device (101) (e.g., the actuator (220) of FIG. 2).

[0024] In one embodiment, to support the deformability of the electronic device (101), the housing (120) of the electronic device (101) may be divided into a first housing part (121) and a second housing part (122) that are interconnected. According to one embodiment, the electronic device (101) may change the shape of the flexible display (110) and / or the electronic device (101) by adjusting the positional relationship of the first housing part (121) and the second housing part (122) using an actuator. Referring to FIGS. 1A to 1E, the flexible display (110) of the electronic device (101) may be arranged across one side of the first housing part (121) and one side of the second housing part (122). A surface on which the flexible display (110) is disposed and formed by the first housing part (121) and the second housing part (122) may be referred to as a front surface of the electronic device (101). Referring to FIGS. 1A to 1E , a front surface of the electronic device (101) that is parallel to the xy plane is illustrated. According to one embodiment, changing the shape of the flexible display (110) by the electronic device (101) may include an operation of changing at least one of a width, a height, and / or an extent of at least a portion that is exposed to the outside within the flexible display (110) (or is visible from the front surface of the housing (120).

[0025] Referring to FIGS. 1A to 1E, an embodiment is illustrated in which a second housing part (122) is slidably coupled to a first housing part (121). For example, a housing (120) of an electronic device (101) may include a second housing part (122) configured to engage with the first housing part (121) so as to be movable between a retracted position and an extended position. A flexible display (110) may be coupled to the first housing part (121) and the second housing part (122). The size of an area of ​​the flexible display (110) visible from the front of the housing (120) may change as the housing (120) is moved between the retracted position and the extended position.

[0026] In one embodiment, the flexible display (110) of the electronic device (101) may be insertable into the first housing part (121) and / or the second housing part (122), or extractable from the first housing part (121) and / or the second housing part (122), based on deformation of the electronic device (101). When the flexible display (110) is inserted into the first housing part (121) and / or the second housing part (122), the size of the area where the flexible display (110) is exposed to the outside may be reduced. When the flexible display (110) is extracted from the first housing part (121) and / or the second housing part (122), the size of the area where the flexible display (110) is exposed to the outside may be increased. Hereinafter, a displaying area of ​​a flexible display (110) may mean an area formed by pixels, among pixels included in the flexible display (110), arranged on an area of ​​the flexible display (110) exposed to the outside. For example, the displaying area may be referred to as an active area of ​​the flexible display (110). For example, an area of ​​the flexible display (110) visible from the front surface of the housing (120) may be referred to as an active area. For example, the active area of ​​the flexible display (110) may correspond to at least a portion of the flexible display (110) distinguished by pixels in an active state, among pixels included in the flexible display (110).

[0027] Referring to FIGS. 1A through 1C, different states (191, 192, 193) of an electronic device (101) and / or a flexible display (110) are illustrated. In one embodiment, the electronic device (101) may switch between the states (191, 192, 193) using an actuator (e.g., actuator 220 of FIG. 2). In one embodiment, the states (191, 192, 193) of the electronic device (101) may be distinguished based on dimensions (e.g., width, height, thickness, and / or an aspect ratio) of the electronic device (101) and / or the flexible display (110). States (191, 192, 193) can be distinguished according to the distance between the first housing part (121) and the second housing part (122) of the electronic device (101). For example, the distance between the first housing part (121) and the second housing part (122) can be the distance between one side of the first housing part (121) (e.g., the left side of the first housing part (121)) and the other side of the second housing part (122) that is parallel to the one side of the first housing part (121) and spaced apart from the one side of the first housing part (121) (e.g., the right side of the second housing part (122)).

[0028] States (191, 193) of FIGS. 1A and 1C may be states in which the surface area of ​​the electronic device (101) and / or the area of ​​the active region of the flexible display (110) are minimized as the electronic device (101) is deformed. Hereinafter, states in which the surface area of ​​the electronic device (101) and / or the area of ​​the active region are minimized, such as states (191, 193), may be referred to as a slide-in state, a rolled state, a closed state, a roll-in state, and / or a contracted state.

[0029] Referring to FIG. 1A, in an exemplary state (191) included in the roll-in state, a first region (110-1) of the flexible display (110) may be exposed to the outside, and a second region (110-2) may be introduced into the housing (120). Referring to FIG. 1C, in an exemplary state (193) included in the roll-in state, a second region (110-2) of the flexible display (110) may be exposed to the outside, and a first region (110-1) may be introduced into the housing (120). For example, the electronic device (101) may move the flexible display (110) along either of the two directions (the direction of the +x axis and / or the direction of the -x axis). The electronic device (101) may have a structure for accommodating at least a portion of the flexible display (110) (e.g., the first region (110-1) and / or the second region (110-2)) that moves along one of the two directions. The first region (110-1) and the second region (110-2) may be different regions spaced apart from each other within the flexible display (110), or may at least partially overlap. Within the states (191, 193) of FIG. 1A and / or FIG. 1C, the first housing part (121) and the second housing part (122) may be positioned based on the reduced position.

[0030] The state (192) of FIG. 1B may be a state in which the surface area of ​​the electronic device (101) and / or the area of ​​the active region of the flexible display (110) are maximized as the electronic device (101) is deformed. Hereinafter, the state in which the surface area of ​​the electronic device (101) and / or the area of ​​the active region are maximized, such as the state (192), may be referred to as a slide-out state, an unrolled state, an opened state, a roll-out state, and / or an expanded state. In one embodiment, the state of the electronic device (101) may further include other states between a state in which the area of ​​the active region is minimized (e.g., states 191 and 193 of FIG. 1A and / or FIG. 1C) and a state in which the area of ​​the active region is maximized (e.g., state 192 of FIG. 1B). The above other states may be referred to as intermediate states, sub-rolled states, and sub-opened states. Within the state (192) of Fig. 1b, the first housing part (121) and the second housing part (122) may be positioned based on their extended positions.

[0031] Referring to FIGS. 1A to 1C, according to one embodiment, the flexible display (110) of the electronic device (101) may have a rectangular shape. In one embodiment, corners of the display (140) may have rounded corners. Hereinafter, among the sides that are boundaries of the rectangular flexible display (110), a first direction parallel to a relatively long side may be referred to as a height direction, and the relatively long side may be referred to as a height. Hereinafter, among the sides that are boundaries of the rectangular display (140), a second direction parallel to a relatively short side may be referred to as a width direction, and the relatively short side may be referred to as a width.

[0032] Referring to FIGS. 1A to 1C, an embodiment of an electronic device (101) that extends or contracts along the width direction of a flexible display (110) or the height direction is illustrated. The embodiment is not limited thereto, and the electronic device (101) may extend or contract along the height direction of the flexible display (110). While switching from the state (191) of FIG. 1A to the state (192) of FIG. 1B, the electronic device (101) may move the second housing part (122) relative to the first housing part (121) (e.g., by withdrawing the second housing part (122) relative to the first housing part (121)) to withdraw the second area (110-2) of the flexible display (110). During the switching from the state (191) of FIG. 1a to the state (192) of FIG. 1b, the second region (110-2) of the flexible display (110) is pulled out, so that the active region of the flexible display (110) can be extended (and / or expanded) along the width direction.

[0033] While switching from the state (192) of FIG. 1b to the state (193) of FIG. 1c, the electronic device (101) can move the second housing part (122) relative to the first housing part (121) (e.g., by introducing the second housing part (122) into the first housing part (121)) to introduce the first area (110-1) of the flexible display (110). While switching from the state (192) of FIG. 1b to the state (193) of FIG. 1c, as the first area (110-1) of the flexible display (110) is introduced into the housing (120), the active area of ​​the flexible display (110) can be reduced in the width direction.

[0034] Although the operation of the electronic device (101) sequentially switching from the state (191) of FIG. 1A to the state (193) of FIG. 1C has been described, the embodiment is not limited thereto. For example, the electronic device (101) may sequentially switch from the state (193) of FIG. 1C to the state (191) of FIG. 1A. For example, the electronic device (101) may switch from the state (193) of FIG. 1C to the state (192) of FIG. 1B corresponding to the roll-out state, and then switch back to the state (193) of FIG. 1C. Similarly, the electronic device (101) may switch from the state (191) of FIG. 1A, which is an example of a roll-in state, to the state (192) of FIG. 1B, which is an example of a roll-out state, and then switch back to the state (191) of FIG. 1A. According to one embodiment, the electronic device (101) can be switched to a roll-in state in which one of different regions (e.g., the first region (110-1) and / or the second region (110-2)) is selectively exposed based on the lifespan and / or deterioration of the pixels included in the flexible display (110). The deterioration of the pixels can be identified or measured by the electronic device (101) to prevent and / or compensate for burn-in of an organic light emitting diode (OLED). For example, if the pixels included in the first region (110-1) have been activated or used for a longer period of time than the other pixels of the flexible display (110), the electronic device (101) can be switched to a state (193) of FIG. 1C, which is a roll-in state in which the second region (110-2) is exposed to the outside.

[0035] In one embodiment, the electronic device (101) may include a camera (130) within a housing (120) positioned below an active area of ​​the flexible display (110). For example, when viewing the front of the electronic device (101) along the z-axis direction, the camera (130) may be positioned below the flexible display (110). For example, when viewing the front of the electronic device (101) along the z-axis direction, the camera (130) may overlap at least a portion of the flexible display (110). In terms of being positioned below the flexible display (110), the camera (130) may be referred to as an under display camera (UDC) and / or an under panel display (UPC). In one embodiment, the active area of ​​a flexible display (110) in which a plurality of pixels are arranged may include a first area (111) configured to transmit ambient light toward a camera (130) positioned below the flexible display (110) and a second area (112) different from the first area (111). The structure of the flexible display (110) in the first area (111) and / or the second area (112) is described with reference to FIG. 4.

[0036] Referring to FIGS. 1A to 1C, when looking at the front of the electronic device (101) along the z-axis, the camera (130) can be positioned under the first region (111) of the flexible display (110). While positioned under the first region (111), the electronic device (101) can obtain information (e.g., images and / or videos) about light that passes through the first region (111) and reaches the camera (130) from the camera (130). When the camera (130) is positioned under the second region (112) different from the first region (111), obtaining images and / or videos through the camera (130) can be stopped as the amount of light reaching the camera (130) decreases. To support capturing images and / or videos using the camera (130), the electronic device (101) can align the position of the camera (130) with respect to the first area (111) of the flexible display (110).

[0037] Referring to FIGS. 1A to 1C , a flexible display (110) is illustrated that includes a first region (111) having a shape extending along one direction (e.g., a direction parallel to the x-axis), but the shape of the first region (111) is not limited thereto. Referring to FIGS. 1D to 1E , different states (194, 195) of the flexible display (110) and / or the electronic device (101) are illustrated that include a first region (111) having a shape corresponding to the shape of a lens of a camera (130) (e.g., a circular shape). The state (194) of the electronic device (101) of FIG. 1D may correspond to the roll-in state described with reference to FIGS. 1A and / or 1C . The state (195) of the electronic device (101) of FIG. 1E may correspond to the roll-out state described with reference to FIG. 1B .

[0038] Referring to FIG. 1D, in an exemplary state (194) included in a roll-in state, a camera (130) of an electronic device (101) may be positioned below a first region (111) of a flexible display (110). The first region (111) may overlap with the camera (130) when the front of the electronic device (101) in the roll-in state is viewed along the z-axis. Since the first region (111) has a shape parallel to the outline of the camera (130) when the front of the electronic device (101) is viewed along the z-axis, as soon as the flexible display (110) is moved with respect to the camera (130), the camera (130) may be moved below a second region (112) different from the first region (111). Among the first region (111) and the second region (112) of the flexible display (110), since the first region (111) has a structure for transmitting light to the camera (130), obtaining an image using the camera (130) may be permitted within a state (194) included in the roll-in state. For example, obtaining an image using the camera (130) positioned below the first region (111) may be permitted within the state (194) of FIG. 1D. According to one embodiment, the electronic device (101) may switch to the roll-in state (e.g., the state (194) of FIG. 1D) based on an input for activating the camera (130), and then execute a function related to the camera (130).

[0039] Referring to FIG. 1E, a state (195) corresponding to a roll-out state is illustrated, in which the electronic device (101) of FIG. 1D is switched as it is deformed. According to one embodiment, the electronic device (101) may include a first region (111) and a third region (113) having a structure for transmitting light toward the camera (130). The embodiment is not limited thereto, and the electronic device (101) may include only one region of the first region (111) or the third region (113). As described above with reference to FIG. 1D, the first region (111) may be aligned with the camera (130) in the roll-in state. Referring to FIG. 1E, the third region (113) may be formed on the flexible display (110) so as to be aligned with the camera (130) in the roll-out state. The third region (113) may overlap with the camera (130) when looking at the front of the electronic device (101) in a rolled-out state along the z-axis. The third region (113) may have a shape parallel to the outline of the camera (130) when looking at the front of the electronic device (101) along the z-axis.

[0040] Referring to FIGS. 1D to 1E , in an electronic device (101) including a first region (111) and a third region (113), acquiring an image using a camera (130) is permitted in a state (194) of FIG. 1D corresponding to a roll-in state and a state (195) of FIG. 1E corresponding to a roll-out state, and may not be permitted in other states (e.g., an intermediate state and / or a free stop state) that are different from the roll-in state and the roll-out state. In one embodiment, when the electronic device (101) identifies an input for activating the camera (130) within the other state, the electronic device (101) may switch to either the roll-in state or the roll-out state, and then execute a function related to the camera (130).

[0041] While the electronic device (101) is deformed, such as in states (191, 192, 193) of FIGS. 1A to 1C and / or states (194, 195) of FIGS. 1D to 1E, the positional relationship between the flexible display (110) and the camera (130) may change. Since the electronic device (101) controls the actuator to move the second housing part (122) relative to the first housing part (121), the positional relationship between the flexible display (110) and the camera (130) may be changed by the actuator. An error may occur while a driving part included in the actuator, such as a stepper motor, is physically moved. The error may be related to a difference between the shape of the electronic device (101) indicated by parameters stored in the electronic device (101) and the actual shape of the electronic device (101). As the period during which the actuator is activated increases, the difference between the actual shape of the electronic device (101) and the shape of the electronic device (101) represented by the parameters may increase as the above error accumulates.

[0042] In one embodiment, the electronic device (101) can use an image identified through the camera (130) to identify the difference. For example, using the image, the electronic device (101) can identify a misalignment between the flexible display (110) and the camera (130). To identify the misalignment, the electronic device (101) can include a pattern formed along a boundary between a first region (111) and a second region (112) of the flexible display (110). Based on whether the pattern is captured by the camera (130), the electronic device (101) can identify a misalignment of the camera (130) with respect to the flexible display (110). Based on identifying the misalignment, the electronic device (101) can control an actuator to align the camera (130) with respect to the first region (111) of the flexible display (110). Based on identifying the misalignment, the electronic device (101) can change one or more parameters (e.g., control information) for controlling the actuator.

[0043] Hereinafter, with reference to FIGS. 2 to 11, an embodiment of an electronic device (101) for identifying and / or compensating for misalignment between a flexible display (110) and a camera (130) is described. According to one embodiment, the electronic device (101) can identify the misalignment using the camera (130) independently of a sensor (e.g., a Hall sensor) for identifying the shape of the flexible display (110) (or the distance between the first housing part (121) and the second housing part (122).

[0044] FIG. 2 illustrates an example of a block diagram of an electronic device (101), according to one embodiment. The electronic device (101) of FIGS. 1A to 1E may be an example of the electronic device (101) of FIG. 2. Referring to FIG. 2, the electronic device (101) may include at least one of a processor (210), a memory (215), a flexible display (110), an actuator (220), and a camera (130). The processor (210), the memory (215), the flexible display (110), the actuator (220), and the camera (130) may be electrically and / or operably coupled with each other by an electronic component, such as a communication bus (202). Hereinafter, the hardwares being operatively coupled may mean that a direct connection or an indirect connection is established between the hardwares, either wired or wireless, so that the second hardware is controlled by the first hardware among the hardwares. Although illustrated based on different blocks, the embodiment is not limited thereto, and some of the hardwares of FIG. 2 (e.g., at least a portion of the processor (210) and the memory (215)) may be included in a single integrated circuit such as a system on a chip (SoC). The type and / or number of hardware included in the electronic device (101) is not limited to that illustrated in FIG. 2. For example, the electronic device (101) may include only some of the hardware components illustrated in FIG. 2.

[0045] According to one embodiment, the processor (210) of the electronic device (101) may include hardware and / or circuitry for processing data based on one or more instructions. As hardware for processing data, the processor (210) may include an arithmetic and logic unit (ALU), a floating point unit (FPU), a field programmable gate array (FPGA), a central processing unit (CPU), and / or an application processor (AP). The number of processors (210) may be one or more. For example, the processor (210) may have a multi-core processor structure such as a dual core, a quad core, or a hexa core.

[0046] According to one embodiment, the memory (215) of the electronic device (101) may include hardware for storing data and / or instructions input to or output from the processor (210). The memory (215) may include, for example, volatile memory such as random-access memory (RAM) and / or non-volatile memory such as read-only memory (ROM). The volatile memory may include, for example, at least one of dynamic RAM (DRAM), static RAM (SRAM), cache RAM, and pseudo SRAM (PSRAM). The non-volatile memory may include, for example, at least one of programmable ROM (PROM), erasable PROM (EPROM), electrically erasable PROM (EEPROM), flash memory, hard disk, compact disc, solid state drive (SSD), and embedded multi-media card (eMMC).

[0047] According to one embodiment, a flexible display (110) of an electronic device (101) can output visualized information to a user. For example, the flexible display (110) can visualize information provided from a controller, such as a graphic processing unit (GPU). The flexible display (110) can include a liquid crystal display (LCD), a plasma display panel (PDP), and / or a plurality of light emitting diodes (LEDs). The LEDs can include organic LEDs (OLEDs). The flexible display (110) can include electronic paper. As described above with reference to FIGS. 1A to 1E , the flexible display (110) can have an at least partially curved shape or a deformable shape.

[0048] According to one embodiment, a flexible display (110) of an electronic device (101) may include a sensor (e.g., a touch sensor panel (TSP)) for detecting an external object (e.g., a user's finger) on the flexible display (110). For example, based on the TSP, a processor (210) of the electronic device (101) may detect an external object that is in contact with the flexible display (110) or floating on the flexible display (110). In response to detecting the external object, the processor (210) may execute a function related to a specific visual object corresponding to a position of the external object on the flexible display (110) among visual objects displayed within the flexible display (110).

[0049] According to one embodiment, an actuator (220) of an electronic device (101) may be configured to move a second housing part (e.g., a second housing part (122) of FIGS. 1A-1E) relative to a first housing part (e.g., a first housing part (121) of FIGS. 1A-1E) of a housing (e.g., a housing (120) of FIGS. 1A-1E). The actuator (220) may change the shape of the flexible display (110) and / or the electronic device (101). The actuator (220) may be referred to as a driving unit. The actuator (220) may include hardware for outputting kinetic energy from electrical energy. For example, the actuator (220) may include a motor and / or a stepper motor. The step motor included in the actuator (220) can be rotated by an angle indicated by a pulse signal applied to the step motor.

[0050] In one embodiment where the actuator (220) includes a motor, the actuator (220) may include a gear (e.g., a rack gear) to change the rotational motion of the motor into linear motion (or translation motion) applied to the flexible display (110). In one embodiment, the actuator (220) may include a plurality of gears engaged to each other to control the rotational force (e.g., torque) of the motor. The plurality of gears may be referred to as a gear assembly, or transmission portion, of the actuator (220).

[0051] In one embodiment, the processor (210) can control the speed and / or direction in which the flexible display (110) and / or the electronic device (101) is deformed by changing the frequency, voltage, and / or current of the power signal applied to the motor of the actuator (220). In one embodiment, the processor (210) can control the speed and / or direction in which the flexible display (110) and / or the electronic device (101) is deformed by controlling the positional relationship of a plurality of gears included in the gear assembly and / or the gear ratio between interconnected gears.

[0052] According to one embodiment, the camera (130) of the electronic device (101) may include optical sensors (e.g., a charged coupled device (CCD) sensor, a complementary metal oxide semiconductor (CMOS) sensor) that generate electrical signals representing the color and / or brightness of light. The plurality of optical sensors included in the camera (130) may be arranged in the form of a two-dimensional array. The camera (130) may acquire the electrical signals of each of the plurality of optical sensors substantially simultaneously, and generate an image corresponding to light reaching the optical sensors of the two-dimensional grid, and including a plurality of pixels arranged two-dimensionally. For example, photographic data captured using the camera (130) may mean one image acquired from the camera (130). For example, video data captured using the camera (130) may mean a sequence of a plurality of images acquired from the camera (130) according to a specified frame rate. Referring to FIGS. 1A to 1E, a camera (130) positioned under a flexible display (110) is exemplarily illustrated, but the number and / or position of the cameras (130) included in the electronic device (101) is not limited to the embodiment of FIGS. 1A to 1E.

[0053] According to one embodiment, one or more instructions (or commands) representing operations and / or actions to be performed on data by the processor (210) may be stored within the memory (215) of the electronic device (101). A set of one or more instructions may be referred to as firmware, an operating system, a process, a routine, a sub-routine, a software application, and / or an application. For example, the electronic device (101) and / or the processor (210) may perform at least one of the operations of FIGS. 3A to 3C when a set of a plurality of instructions distributed in the form of an operating system, firmware, driver, and / or application is executed. Hereinafter, the fact that an application is installed in an electronic device (101) may mean that one or more instructions provided in the form of an application are stored in the memory (215) of the electronic device (101), and that the one or more applications are stored in a format executable by the processor (210) of the electronic device (101) (e.g., a file having an extension specified by the operating system of the electronic device (101)).

[0054] According to one embodiment, the processor (210) of the electronic device (101) can control the camera (130) based on the execution of the camera application (225). The processor (210) can execute the camera application (225) based on an input indicating the execution of the camera application (225). The input indicating the execution of the camera application (225) can be identified by a touch gesture (or a drag gesture) on a visual object (e.g., an icon) displayed on the flexible display (110) and representing the camera application (225). The input indicating the execution of the camera application (225) can be identified by the pressing of a designated button exposed externally through a portion of the housing of the electronic device (101). The embodiment is not limited thereto, and the input indicating the execution of the camera application (225) may be identified by a voice command and / or a user's utterance including a natural language sentence related to the camera (130). The input indicating the execution of the camera application (225) may be included in the input activating the camera (130).

[0055] In one embodiment, while the camera application (225) is running, the processor (210) may perform an operation to identify a positional relationship between the flexible display (110) and the camera (130). In response to an input activating the camera (130), the processor (210) may acquire an image through the camera (130). From the image, the processor (210) may acquire information for identifying a positional relationship between the flexible display (110) and the camera (130). For example, the processor (210) may identify, from the image, a visual object corresponding to at least a portion of a pattern for distinguishing a first region (e.g., the first region (111) of FIGS. 1A to 1E) of the flexible display (110) configured to transmit light toward the camera (130). Based on identifying the above visual object, the electronic device (101) can execute a function for aligning the flexible display (110) and the camera (130), for example, a function for controlling the actuator (220).

[0056] According to one embodiment, the processor (210) of the electronic device (101) may control the actuator (220) using actuator control information (230) stored in the memory (215). The actuator control information (230) may include information required for driving a step motor included in the actuator (220). For example, the actuator control information (230) may include information on the amplitude and / or pulse width of a pulse signal required for controlling the step motor. For example, the actuator control information (230) may include information on the degree to which the step motor rotates with respect to a unit pulse applied to the step motor. For example, the actuator control information (230) may include a movement distance of the flexible display (110) and / or the housing (e.g., the first housing part (121) and / or the second housing part (122)) of the electronic device (101) for the unit pulse. For example, the actuator control information (230) may include information indicating a relationship between the rotational speed (e.g., step) of the step motor and the movement distance.

[0057] According to one embodiment, when the processor (210) identifies a visual object corresponding to at least a portion of the pattern from an image acquired from the camera (130), the processor (210) may control the actuator (220) to align the flexible display (110) and the camera (130). Based on the aligning of the flexible display (110) and the camera (130), the processor (210) may change the actuator control information (230). For example, the processor (210) may change the actuator control information (230) to prevent an image including the visual object from being output from the camera (130).

[0058] Hereinafter, with reference to FIGS. 3A to 3C, the operation of the processor (210) of the electronic device (101) performed to align the flexible display (110) and the camera (130) is described.

[0059] FIGS. 3A to 3C illustrate an example of a flowchart of an electronic device according to one embodiment. The operations of the electronic device described with reference to FIGS. 3A to 3C may be performed by the electronic device (101) of FIGS. 1A to 1E and / or FIG. 2 and / or the processor (210) of FIG. 2.

[0060] Referring to FIG. 3A, within operation (310), according to one embodiment, a processor of an electronic device may acquire an image from a camera in response to an input activating the camera (e.g., camera (130) of FIGS. 1A-1E and / or 2). The input may include an input for executing a camera application (225) of FIG. 2. Operation (310) may be performed while the shape and / or state of the electronic device is aligned with a portion of the flexible display (e.g., first region (111) of FIGS. 1A-1E) configured to transmit light, wherein the camera is positioned under a flexible display (e.g., flexible display (110) of FIGS. 1A-1E and / or 2). For example, the processor may control the actuator (220) of FIG. 2 so that the camera is positioned below the portion of the flexible display, and then perform the operation (310).

[0061] The embodiment is not limited thereto, and the processor of the electronic device may acquire an image of the operation (310) based on a test operation to verify the alignment of the camera and the flexible display. The test operation may be performed while the electronic device is being produced, manufactured, and / or assembled. The test operation may include a background process (e.g., a self-diagnosis process) executed by the electronic device.

[0062] Referring to FIG. 3A, in operation (320), according to one embodiment, a processor of an electronic device may identify whether a visual object corresponding to a pattern formed on a rear surface of a flexible display is included in an image of operation (310). In an electronic device including a camera positioned below a flexible display, the rear surface of the flexible display facing the camera may include a pattern disposed along a boundary between a first region configured to transmit light toward the camera (e.g., the first region (111) of FIGS. 1A to 1E) and a second region different from the first region (e.g., the second region (112) of FIGS. 1A to 1E). A pattern may be formed on the rear surface of the flexible display to guide alignment of the camera and the flexible display. Exemplary shapes and / or positions of the patterns formed on the rear surface of the flexible display are described with reference to FIGS. 5 to 6.

[0063] In one embodiment, a processor of an electronic device may identify a visual object corresponding to the pattern from the image of the action (310) by comparing a reference image related to the pattern and an image of the action (310). The processor may identify the visual object from the image of the action (310) based on one or more feature points included in the image of the action (310). The embodiment is not limited thereto, and the processor may identify the visual object from the image of the action (310) using a neural network (or model), such as a convolutional neural network (CNN) and / or a long-short term memory (LSTM).

[0064] In one embodiment, since the pattern of the action (320) is formed at a boundary between a first region configured to transmit light toward the camera and a second region different from the first region, inclusion of a visual object corresponding to the pattern in an image may mean that at least a portion of the camera is positioned below the boundary and / or the second region. If at least a portion of the camera is positioned below the second region, capturing of images and / or video using at least a portion of the camera may be interrupted because light directed to the camera is occluded by the second region. For example, vignetting may occur in a portion of an image and / or video corresponding to at least a portion of the camera.

[0065] In one embodiment, the processor may search for a visual object corresponding to the pattern in the image of operation (310) to identify whether vignetting occurs. If vignetting occurs, the processor may perform an operation to prevent the vignetting. In terms of a mark formed to identify vignetting, the pattern may be referred to as a vignetting recognition mark. Based on identifying an image including a visual object corresponding to at least a portion of the pattern (320 - Yes), the processor may perform operation (330). Having identified a visual object corresponding to at least a portion of the pattern, the processor may determine that at least a portion of the camera overlaps a second area of ​​the flexible display when looking at the front of the electronic device. The processor may control an actuator to reduce the size of at least a portion of the camera overlapping the second area. If the visual object is not identified from the image (320 - No), the processor may perform operation (360). For example, if the visual object is not identified from the image (320-No), actions (330, 340, 350) may not be performed, or performing actions (330, 340, 350) may be bypassed.

[0066] Referring to FIG. 3A, in operation (330), according to one embodiment, a processor of an electronic device may identify a location of a visual object within an image. For example, the processor may identify coordinate values ​​representing the location of the visual object within the image. The processor may identify a distance between an edge of the image and the visual object. The processor identifying the location of the visual object within the image based on operation (330) may be performed to align a camera and a flexible display using the location.

[0067] Referring to FIG. 3A, in operation (340), according to one embodiment, a processor of an electronic device may control an actuator (e.g., actuator (220) of FIG. 2) to align a camera and a flexible display. For example, the processor may control the actuator based on a location identified based on operation (330). For example, the processor may use the location to determine a movement distance required for the entire image sensor of the camera to move under a first region of the flexible display. The processor may control the actuator based on the determined movement distance. In one embodiment that controls an actuator including a stepper motor, the processor may determine a number of pulses to be applied to the stepper motor based on a movement distance per unit pulse and the determined movement distance. The processor may transmit a pulse signal based on the number of pulses to the stepper motor. For example, to align a camera with respect to a first region of a flexible display, the processor may transmit, to the actuator, a pulse signal indicating a movement distance of the flexible display based on a pulse count and / or a control signal including the pulse signal. The pulse signal may be included in a control signal transmitted from the processor to the actuator.

[0068] In one embodiment, the processor may obtain a control signal to be transmitted to the one or more motors (e.g., the stepper motor) included in the actuator to align the camera and the flexible display based on a relationship between rotational angles of the one or more motors included in the actuator and a movement distance of the flexible display with respect to the camera. In one embodiment, based on an image including a visual object of operation (320), the processor may control the actuator to align the camera with respect to a first area of ​​the flexible display. Based on the control of the actuator, the processor may align the camera and the flexible display such that the camera is positioned below the first area of ​​the flexible display.

[0069] Referring to FIG. 3A, in operation (350), according to one embodiment, a processor of an electronic device may change control information for an actuator (e.g., actuator control information (230) of FIG. 2). For example, the control information indicating a relationship between rotation angles of one or more motors included in the actuator and a movement distance of the flexible display may be stored in a memory of the electronic device. Identifying a visual object corresponding to a pattern formed on the rear surface of the flexible display in the image may indicate that the flexible display and the camera are misaligned due to the operation of the actuator. The processor that has identified the visual object may align the flexible display and the camera based on the control of the actuator in operation (340), and change the control information used to control the actuator based on operation (350). For example, the processor may change the control information so that the camera is moved under the first region of the flexible display by an actuator controlled by the changed control information.

[0070] Referring to FIG. 3A, in operation (360), according to one embodiment, a processor of an electronic device may execute a function related to a camera (e.g., capturing). For example, the processor may display at least a portion of an image acquired from the camera on the flexible display as a preview image. For example, based on the processor controlling the actuator by performing operation (340), after the camera is moved below the first region of the flexible display, the processor may acquire another image to be displayed on the flexible display in response to the input of operation (310). The other image may be referred to as a preview image. The processor may acquire an image and / or a video by executing the function. The processor may store the acquired image and / or the acquired video in a memory (e.g., the memory (215) of FIG. 2).

[0071] The operation of the electronic device described with reference to FIG. 3A can be performed by an electronic device capable of acquiring an image using the camera (130) in all switchable states based on the deformation of the actuator, such as the electronic device (101) described with reference to FIGS. 1A to 1C. Referring to FIGS. 1D to 1E, the size and / or position of the first region (111) (or the third region (113)) configured to transmit light toward the camera (130) may prevent the acquisition of an image using the camera (130) in certain states of the electronic device (101) (e.g., an intermediate state and / or a free stop state).

[0072] Referring to FIG. 3B, in operation (312), a processor of an electronic device according to an embodiment may, in response to an input activating a camera, control an actuator to move the camera below a first area of ​​a flexible display. The first area of ​​operation (312) may include the first area (111) of FIGS. 1A to 1E and / or the first area (111) and the third area (113) of FIGS. 1C to 1E. The processor may determine a rotation angle of the motor for moving the camera below the first area by using a relationship between a rotation angle of a motor included in the actuator and a movement distance of the flexible display. The processor may control the actuator based on the determined rotation angle to perform operation (312).

[0073] Referring to FIG. 3B, in operation (314), according to one embodiment, a processor of an electronic device may acquire an image using a camera. Operation (314) of FIG. 3B may be performed similarly to operation (310) of FIG. 3A. The processor may acquire an image by performing operation (314) while the camera is moved below the first region of the flexible display based on operation (312).

[0074] Referring to FIG. 3B , within operation (322), the processor of the electronic device according to one embodiment may identify whether a visual object corresponding to a pattern formed along the boundary of the first region and the second region of the flexible display is included in the image of operation (314). The pattern and / or visual object of operation (322) may correspond to the pattern and / or visual object of operation (320) of FIG. 3A . If an image including the visual object of operation (322) is identified (322 - Yes), the processor may perform operations (330, 340, 350) of FIG. 3B . Operations (330, 340, 350) of FIG. 3B may correspond to operations (330, 340, 350) of FIG. 3A . If the visual object of operation (322) is not identified from the image (322 - No), the processor may perform operation (360). The operation (360) of Fig. 3b may correspond to the operation (360) of Fig. 3a.

[0075] Referring to FIG. 3B, a processor that identifies an image including a visual object of operation (322) may align a camera and a flexible display based on operations (330, 340, 350). The processor that aligns the camera and the flexible display may change or update information used to move the flexible display of operation (312) (e.g., information indicating a relationship between a rotation angle of a motor and a movement distance of the flexible display). For example, a processor that controls a stepper motor of an actuator based on a first number of steps specified in operation (312) may determine a sum of the first number and the second number as a parameter used to control the stepper motor to move the camera below the first area when controlling the stepper motor based on a second number of steps based on operation (340). For example, after operation (340), the sum of the first number and the second number can be used to move the camera below the first area.

[0076] Referring to FIG. 3C, in operation (316), according to one embodiment, a processor of an electronic device may control an actuator in response to an input for inserting and / or withdrawing a flexible display. The input may include a user input for deformation of the electronic device and / or the flexible display. The processor, having identified the input, may control the actuator to move the flexible display. By moving the flexible display, the positional relationship between the camera located under the flexible display and the flexible display may be changed.

[0077] Referring to FIG. 3C, a processor controlling an actuator based on operation (316) may perform operation (314). Based on the image acquired by operation (314), the processor may perform operations (322, 330, 340, 350). Based on operations (322, 330, 340, 350), the processor may adjust the position of the camera with respect to the flexible display. For example, a processor that identifies a visual object within an image acquired after controlling the actuator may align the camera and the flexible display based on operations (330, 340, 350). After performing the alignment, the processor may complete the insertion and / or withdrawal of the flexible display based on operation (370).

[0078] The operations described with reference to FIG. 3C may be performed based on a background process executed by the processor while controlling the actuator based on input for inlet and / or outlet of the flexible display. For example, the processor may perform the alignment of the camera and the flexible display based on FIG. 3C independently of the screen displayed on the flexible display. Any of the operations (314, 322, 330, 340, 350) of FIG. 3C may be performed without displaying a screen on the flexible display.

[0079] As described above, according to one embodiment, the processor of the electronic device can control the actuator to prevent the camera of the electronic device from being obscured by a specific area of ​​the flexible display (e.g., the second area (112) of FIGS. 1A to 1E) in the UDC and / or UPC structure.

[0080] Hereinafter, with reference to FIG. 4, an exemplary structure of a flexible display including a first region configured to transmit light toward a camera is described.

[0081] FIG. 4 illustrates an example of the structure of a portion of a flexible display (110) overlapping a camera (130). The electronic device (101) of FIGS. 1A to 1E and FIG. 2 may include the camera (130) and the flexible display (110) described with reference to FIG. 4.

[0082] Referring to FIG. 4, in one embodiment of an electronic device (101) in which a camera (130) is positioned below a flexible display (110), a second region (112) of the flexible display (110) that is different from a first region (111) configured to transmit light to the camera (130) may be configured to surround the first region (111). The second region (112) may have a structure different from the structure for transmitting light to the camera (130). For example, the second region (112) may not include a structure including one or more openings for transmitting light to the camera (130). Hereinafter, with reference to FIG. 4, an example of a structure formed in the first region (111) of the flexible display (110) for transmitting light to the camera (130) will be described.

[0083] Referring to FIG. 4, an enlarged view (111-1) of a portion of a first region (111) of a flexible display (110) configured to be positioned on a camera (130) is illustrated, from a perspective of viewing the front of the electronic device (101) along the z-axis. Referring to the enlarged view (111-1) of FIG. 4, the first region (111) of the flexible display (110) may include a plurality of pixels (430) that are uniformly spaced from each other and an opaque metal layer (410) positioned below the plurality of pixels (430). Each of the plurality of pixels (430) may include sub-pixels (431, 432, 433) configured to emit different colors. For example, the colors may include three primary colors of light (e.g., red, green, and blue). For example, a sub-pixel (431) may be configured to emit red light. A sub-pixel (432) may be configured to emit green light. A sub-pixel (433) may be configured to emit blue light.

[0084] For example, the opaque metal layer (410) may include a plurality of openings (420) positioned between a plurality of pixels (430) when the first region (111) is viewed along the z-axis. For example, each of the plurality of openings (420) may be partially surrounded by pixels. For example, the plurality of pixels (430) may be positioned along the periphery of each of the plurality of openings (420). For example, the opaque metal layer (410) may be positioned below an emissive layer (or panel layer) that includes a plurality of pixels (430) that are uniformly spaced from each other. Light directed from the outside of the electronic device (101) toward the front surface of the electronic device (101) where the flexible display (110) is positioned may be propagated below the flexible display (110) along the plurality of openings (420) included in the opaque metal layer (410). For example, the light may be transmitted toward a camera (130) positioned below the flexible display (110) along a plurality of apertures (420). For example, an image acquired by the camera (130) may represent light that has passed through the plurality of apertures (420) formed in the first region (111) and reached the camera (130).

[0085] Referring to FIG. 4, when the first region (111) is viewed along the z-axis, a plurality of apertures (420) may be positioned between a plurality of pixels (430). Meanwhile, in a second region (112) different from the first region (111), a plurality of pixels (430) may be positioned adjacent to each other in all directions on the xy plane in order to provide a high-resolution screen. For example, the spacing between the plurality of apertures (420) and / or the plurality of pixels (430) may be minimized in the second region (112) of the flexible display (110). Since the spacing between the plurality of pixels (430) is minimized in the second region (112) of the flexible display (110), the first density of the pixels (430) in the first region (111) may be lower than the second density of the pixels (430) in the second region (112).

[0086] As described above, according to one embodiment, the flexible display (110) of the electronic device (101) may include a first region (111) including a plurality of openings (420) for transmitting light from the front to the rear of the flexible display (110) and a second region (112) in which the plurality of openings (420) are not formed. The electronic device (101) including a camera (130) positioned under the flexible display (110) may identify whether the camera (130) is positioned under the first region (111) of the flexible display (110) using an image acquired from the camera (130). In order to identify a positional relationship between the camera (130) and the first region (111) using the image, the electronic device (101) may include a flexible display (110) in which a pattern for identifying the positional relationship is formed.

[0087] Fig. 5 illustrates an example of a pattern formed on one side of a flexible display (110) toward which a camera (130) is directed. The electronic device (101) of Figs. 1a to 1e and Fig. 2 may include a flexible display (110) having a pattern formed thereon as described with reference to Fig. 5.

[0088] Referring to FIG. 5, a cross-sectional view of a flexible display (110) included in an electronic device (101) taken along line AA' according to one embodiment is illustrated. The flexible display (110) may include a panel layer (510), a light shielding layer (520), and a metal layer (530) sequentially stacked along the direction of the -z axis. The light shielding layer (520) may be referred to as an emboss layer and / or a black emboss layer. The metal layer (530) may include the opaque metal layer (410) of FIG. 4. Referring to FIG. 5, the flexible display (110) may include a first region (111) configured to transmit light to the camera (130) by overlapping with the camera (130), and a second region (112) designed not to overlap with the camera (130). In the first region (111) of the flexible display (110), at least a portion of the light-shielding layer (520) and / or the metal layer (530) may be opened or perforated.

[0089] According to one embodiment, the flexible display (110) of the electronic device (101) may include a pattern formed on one side facing the camera (130) (e.g., the rear side of the flexible display (110)). Referring to FIG. 5, the pattern may be formed on one side of the metal layer (530). The pattern may be formed along the edge of an opening of the metal layer (530) formed to transmit light to the first region (111) on the side of the metal layer (530) facing the camera (130). Referring to FIG. 5, the pattern may be formed along the boundary between the first region (111) and the second region (112). For example, the pattern may have the shape of an outline of the first region (111).

[0090] Referring to FIG. 5, different examples of metal layers (e.g., metal layers 530-1 and 530-2) including a pattern representing a boundary between a first region (111) and a second region (112) are illustrated. Referring to the metal layer (530-1), a pattern (540) having a dashed line shape may be formed along the boundary between the first region (111) and the second region (112). The pattern (540) having a dashed line shape may be formed by a designated color and / or a designated material (e.g., a fluorescent material). The pattern (540) may be formed by an engraved or embossed metal layer (530-1). Although a pattern (540) formed along the periphery of the first region (111) is illustrated as an example, the embodiment is not limited thereto. For example, the pattern (540) may be partially formed on the left edge and / or the right edge of the first region (111) extending along the x-axis, among the edges of the first region (111). For example, the pattern (540) may not be formed on edges other than the left edge and the right edge among the edges of the first region (111).

[0091] Referring to the metal layer (530-2) of FIG. 5, patterns (542, 544) having a shape indicating specific points between the first region (111) and the second region (112) may be formed. For example, the patterns (542, 544) may be positioned at two points facing each other on the boundary line between the first region (111) and the second region (112). The patterns (542, 544) may indicate the points based on the shape of a crosshair. The embodiment is not limited thereto.

[0092] According to one embodiment, the electronic device (101) may execute a function for aligning the flexible display (110) and the camera (130) based on identifying patterns (540, 542, 544) illustrated with reference to FIG. 5 from an image acquired from the camera (130). Hereinafter, an exemplary operation of the electronic device (101) for aligning the flexible display (110) and the camera (130) is described with reference to FIG. 6.

[0093] FIG. 6 illustrates an example of an operation of an electronic device (101) for aligning a camera (130) and a flexible display (110). The electronic device (101) of FIGS. 1A to 1E, FIG. 2, and / or the processor (210) of FIG. 2 may perform the operation of the electronic device (101) described with reference to FIG. 6.

[0094] Referring to FIG. 6, an example of an image (610) acquired by an electronic device (101) using a camera (130) is illustrated in an exemplary state (601) where at least a portion of the camera (130) is positioned below a second region (112) of a flexible display (110). The image (610) of FIG. 6 may be acquired based on operation (310) of FIG. 3A and / or operation (314) of FIG. 3B. In one embodiment where the camera (130) is positioned below the flexible display (110), the flexible display (110) may include a first region (111) including one or more openings for transmitting light (e.g., a plurality of openings (420) of FIG. 4) and a second region (112) formed independently of the one or more openings. Light passing through the flexible display (110) can reach the first part of the camera (130) positioned below the first region (111). No light can reach the second part of the camera (130) positioned below the second region (112) because the light directed toward the flexible display (110) is blocked by the second region (112).

[0095] Referring to FIG. 6, when a part of the camera (130) is positioned under the second area (112) of the flexible display (110), the image (610) obtained from the camera (130) can be divided into a first part (630) corresponding to the part of the camera (130) positioned under the first area (111) of the flexible display (110) and a second part (640) corresponding to the part of the camera (130) positioned under the second area (112) of the flexible display (110). Since the light passing through the first area (111) of the flexible display (110) reaches the part of the camera (130) corresponding to the first part (630), the first part (630) of the image (610) can have a color distribution corresponding to the light. Since a portion of the camera (130) corresponding to the second portion (640) is covered by the second area (112) of the flexible display (110), the second portion (640) of the image (610) may have a color (e.g., substantially black) below a specified brightness. Between the first portion (630) and the second portion (640) of the image (610), a visual object (620) corresponding to at least a portion of a pattern formed between the first area (111) and the second area (112) of the flexible display (110) may be included.

[0096] Referring to FIG. 6, an image (610) obtained from a camera (130) that at least partially overlaps a second region (112) of a flexible display (110) may include a second portion (640) that is obscured by the second region (112). The inclusion of the second portion (640) in the image (610) may indicate that the camera (130) does not fully receive ambient light (or external light) of the electronic device (101). To remove or reduce the unintentional second portion (640) from the image (610), the electronic device (101) may align the flexible display (110) and the camera (130) to move the camera (130) below the first region (111).

[0097] According to one embodiment, the electronic device (101) can detect a visual object (620) corresponding to a pattern within the image (610) to identify a second portion (640) covered by the second region (112). Based on the shape of the visual object (620) included in the image (610) (in the shape of an arc protruding toward the -x direction within the exemplary state (601) of FIG. 6), the electronic device (101) can identify the second portion (640) covered by the second region (112) within the image (610). According to one embodiment, the electronic device (101) can identify a location of the visual object (620) within the image (610) and / or a distance (650) between an edge of the image (610) and the visual object (620).

[0098] Referring to FIG. 6, a portion of an image (610) is illustrated that includes a visual object (621) corresponding to a portion of a pattern. A pixel (630) of a camera (130) of an electronic device (101) may include sub-pixels based on a Bayer pattern (e.g., a green sub-pixel indicated by "G," a red sub-pixel indicated by "R," and a blue sub-pixel indicated by "B"). The pixel (630) of the camera (130) may correspond to each of the light sensors included in the camera (130) for receiving light. The electronic device (101) may identify the position of the pattern on the camera (130) by using the position of the visual object (621) within the image (610) and the size of the pixel (630) (e.g., the horizontal size (d1) and / or the vertical size (d2) of the pixel (630). Using the distance (650) identified based on the number (or unit) of pixels included in the image (610), the electronic device (101) can identify the movement distance and / or movement direction of the flexible display (110) and / or housing (120) required to move the camera (130) below the first area (111). The electronic device (101) can control an actuator (e.g., actuator (220) of FIG. 2) based on the movement distance and / or movement direction.

[0099] For example, the electronic device (101) can control the actuator to move the second housing part (122) relative to the first housing part (121) based on the movement distance. For example, the electronic device (101) can determine the number of steps of the step motor included in the actuator based on the movement distance. Based on the control of the actuator, the electronic device (101) can move the camera (130) below the first area (111) of the flexible display (110). As the camera (130) is moved below the first area (111) of the flexible display (110), the size of a portion (e.g., the second portion (640)) corresponding to the second area (112) in an image (e.g., the image (610)) acquired from the camera (130) can be reduced or eliminated.

[0100] In one embodiment where the electronic device (101) includes an actuator based on a stepper motor, the electronic device (101) that has identified a visual object (620) from an image (610) can identify an error caused by the control of the stepper motor. To compensate for or eliminate the error, the electronic device (101) can change information used to control the stepper motor (e.g., actuator control information (230) of FIG. 2). For example, the electronic device (101) can change a movement distance per unit pulse input to the stepper motor (e.g., a movement distance of the second housing part (122) relative to the first housing part (121). For example, the electronic device (101) can identify the rotation number (or step number) and the movement distance of the second housing part (122) relative to the first housing part (121) based on the position (or movement distance) of the visual object (620) within the image (610) per rotation number (or step number) of the step motor. The electronic device (101) can store the relationship between the identified rotation number and the movement distance in a memory (e.g., the memory (215) of FIG. 2) as information for use in controlling an actuator (e.g., actuator control information (230) of FIG. 2).

[0101] As described above, according to one embodiment, the electronic device (101) can execute a function for aligning the camera (130) and the first region (111) by using a pattern representing the first region (111) of the flexible display (110). The electronic device (101) can obtain information used to control an actuator (e.g., information for controlling a step motor included in the actuator) by using the pattern. The electronic device (101) can execute the function by using an image (610) acquired from the camera (130), thereby aligning the camera (130) and the first region (111) without an additional sensor for identifying the positional relationship between the camera (130) and the first region (111).

[0102] In one embodiment, an electronic device (101) including a flexible display (110) movable on a camera (130) may have a structure for preventing damage to the camera (130) by foreign substances (e.g., dust) within the electronic device (101). The structure may include a structure that at least partially covers a lens of the camera (130), such as a shutter (or aperture). The aperture may be controlled to cover the entire lens before the camera (130) is activated (or while the camera (130) is in an inactive state). Based on an input for activating the camera (130), such as operation (310) of FIG. 3A and / or operation (314) of FIG. 3B, the electronic device (101) may control the aperture so that the aperture is fully opened. Hereinafter, with reference to FIGS. 7 and 8, an example of a structure included in an electronic device (101) to prevent damage to the camera (130) by the foreign substance is described.

[0103] FIG. 7 illustrates an example of an electronic device (101) including a sweeper structure (730) associated with a camera (130). The electronic device (101) of FIGS. 1A to 1E and / or FIG. 2 may include the sweeper structure (730) described with reference to FIG. 7.

[0104] Referring to FIG. 7, a cross-sectional view of an electronic device (101) taken along line AA' according to one embodiment is illustrated. The electronic device (101) may include a printed circuit board (PCB) (720) and a metal layer (710). Referring to FIG. 7, a camera (130) included in the electronic device (101) may include a sweeper structure (730) positioned toward the flexible display (110). The sweeper structure (730) may include an object for removing and / or moving foreign substances, such as a brush and / or a sponge. The sweeper structure (730) may be positioned along an edge of a lens of the camera (130). The flexible display (110) may be moved relative to the camera (130) while the second housing part (122) is moved relative to the first housing part (121). While the flexible display (110) is moved relative to the camera (130), foreign substances on at least a portion (e.g., a first area (111) of the flexible display (110)) of one side (e.g., a rear side of the flexible display (110)) of the flexible display (110) can be removed by the sweeper structure (730).

[0105] Referring to FIG. 7, a sweeper structure (730) positioned along the edge of the lens of the camera (130) may form an at least partially sealed space between the lens and the first region (111) of the flexible display (110). The sweeper structure (730) may reduce the probability of foreign substances such as dust entering the space. In one embodiment, the electronic device (101) may further include the sweeper structure (730) to prevent the quality of images and / or videos acquired from the camera (130) from being reduced by the foreign substances.

[0106] FIG. 8 illustrates an example of an electronic device (101) including a rail structure associated with a camera (130). The electronic device (101) of FIGS. 1A to 1E and / or FIG. 2 may include the rail structure described with reference to FIG. 8.

[0107] Referring to FIG. 8, according to one embodiment, an electronic device (101) may include a rail (810) that is movable according to the movement of a flexible display (110) relative to a camera (130). For example, the position of the camera (130) on the rail (810) may change as the electronic device (101) switches between states (191, 192, 193) of FIGS. 1A to 1C and / or states (194, 195) of FIGS. 1D to 1E. The camera (130) of the electronic device (101) may include rail hooks (821, 822) for the rail (810). The rail (810) may have a shape that at least partially surrounds the camera (130). For example, the rail (810) may have a shape to prevent foreign matter (e.g., dust) from moving into the space between the camera (130) and the flexible display (110).

[0108] FIG. 9 illustrates an example of an operation of an electronic device (101) performed to obtain information for controlling an actuator. The electronic device (101) of FIGS. 1A to 1E and FIG. 2 may perform the operation described with reference to FIG. 9 to obtain information used for controlling an actuator (e.g., actuator (220) of FIG. 2). The information may include a relationship between a rotation angle of a motor included in the actuator and a movement distance of the flexible display (110). For example, in one embodiment where the actuator includes a step motor, the information may indicate a movement distance of the flexible display (110) per step of the step motor. The operation described with reference to FIG. 9 may be performed during a production process of the electronic device (101). The embodiment is not limited thereto, and the operations described with reference to FIG. 9 may be performed during a user's repair work of the electronic device (101), such as self-repair. The electronic device (101) obtaining information for controlling the actuator is not limited to the embodiment of FIG. 9. For example, the information may be provided by a vendor of the actuator and / or the electronic device (101).

[0109] Referring to FIG. 9, the electronic device (101) can obtain information for controlling an actuator by using a panel (910) spaced apart from the electronic device (101) by a specified distance (d). The panel (910) may be referred to as a calibration chart. The panel (910) may include a pattern (920) recognizable by a camera (130). Although a pattern (920) having a broken line shape is illustrated as an example, the embodiment is not limited thereto.

[0110] Referring to FIG. 9, by controlling the camera (130) positioned toward the panel (910), the electronic device (101) can obtain a first image of the panel (910). While the camera (130) is positioned at the first point (P1), the electronic device (101) can obtain the first image. The electronic device (101) that has obtained the first image can control an actuator to move the camera (130). Within the exemplary state of FIG. 9, spaced apart from the panel (910) by a specified distance (d), after controlling the actuator to move the camera (130) from the first point (P1) to the second point (P2), the electronic device (101) can obtain a second image from the camera (130). The electronic device (101) can move the camera (130) from a first point (P1) to a second point (P2) by rotating a motor included in an actuator according to a specified rotation angle.

[0111] In one embodiment, the electronic device (101) can identify a relationship between a movement distance of the flexible display (110) and / or the camera (130) for the specified rotation angle by comparing positions of visual objects corresponding to the pattern (920) within the first image and the second image. For example, the distance of the visual objects within the first image and the second image can represent a distance moved by the actuator when the camera (130) is rotated along the specified rotation angle. Using the relationship between the rotation angle and the distance, the electronic device (101) can store information representing the relationship. Using the information, the electronic device (101) can control the actuator to switch to a target state (e.g., a roll-in state, a roll-out state, and / or an intermediate state between the roll-in state and the roll-out state).

[0112] After obtaining information indicating the relationship between the rotation angle of the actuator and the movement distance of the camera (130), as described with reference to FIG. 9, the actuator may deteriorate as the electronic device (101) controls the actuator using the information. The deterioration of the actuator may cause misalignment of the flexible display (110) and the camera (130), as described above with reference to FIGS. 1A to 8. In one embodiment, the electronic device (101) may identify the misalignment using a pattern formed on one side of the flexible display (110) (e.g., one side of the flexible display (110) toward which the camera (130) faces). Based on identifying the misalignment, the electronic device (101) may control the actuator to align the flexible display (110) and the camera (130). Based on identifying the above misalignment, the electronic device (101) can change or update the information that was acquired based on the operation described with reference to FIG. 9.

[0113] Hereinafter, with reference to FIGS. 10 to 12, an embodiment of an electronic device (101), a flexible display (110), and a camera (130) of FIGS. 1A to 9 will be described. For example, the electronic device (901) of FIGS. 10 to 12 may be an example of the electronic device (101) of FIGS. 1A to 9. For example, the camera module (1080) of FIGS. 10 to 12 may be an example of the camera (130) of FIGS. 1A to 9. For example, the display module (1060) of FIGS. 10 to 12 may be an example of the flexible display (110) of FIGS. 1A to 8.

[0114] FIG. 10 is a block diagram of an electronic device (1001) within a network environment (1000) according to various embodiments. Referring to FIG. 10, in the network environment (1000), the electronic device (1001) may communicate with the electronic device (1002) via a first network (1098) (e.g., a short-range wireless communication network), or may communicate with at least one of the electronic device (1004) or the server (1008) via a second network (1099) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (1001) may communicate with the electronic device (1004) via the server (1008). According to one embodiment, the electronic device (1001) may include a processor (1020), a memory (1030), an input module (1050), an audio output module (1055), a display module (1060), an audio module (1070), a sensor module (1076), an interface (1077), a connection terminal (1078), a haptic module (1079), a camera module (1080), a power management module (1088), a battery (1089), a communication module (1090), a subscriber identification module (1096), or an antenna module (1097). In some embodiments, the electronic device (1001) may omit at least one of these components (e.g., the connection terminal (1078)), or may have one or more other components added. In some embodiments, some of these components (e.g., sensor module (1076), camera module (1080), or antenna module (1097)) may be integrated into a single component (e.g., display module (1060)).

[0115] The processor (1020) may, for example, execute software (e.g., a program (1040)) to control at least one other component (e.g., a hardware or software component) of the electronic device (1001) connected to the processor (1020) and perform various data processing or operations. According to one embodiment, as at least a part of the data processing or operations, the processor (1020) may store commands or data received from other components (e.g., a sensor module (1076) or a communication module (1090)) in a volatile memory (1032), process the commands or data stored in the volatile memory (1032), and store result data in a non-volatile memory (1034). According to one embodiment, the processor (1020) may include a main processor (1021) (e.g., a central processing unit or an application processor) or an auxiliary processor (1023) (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or together with the main processor (1021). For example, when the electronic device (1001) includes the main processor (1021) and the auxiliary processor (1023), the auxiliary processor (1023) may be configured to use less power than the main processor (1021) or to be specialized for a given function. The auxiliary processor (1023) may be implemented separately from the main processor (1021) or as a part thereof.

[0116] The auxiliary processor (1023) may control at least a portion of functions or states associated with at least one component (e.g., the display module (1060), the sensor module (1076), or the communication module (1090)) of the electronic device (1001), for example, on behalf of the main processor (1021) while the main processor (1021) is in an inactive (e.g., sleep) state, or together with the main processor (1021) while the main processor (1021) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (1023) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (1080) or a communication module (1090)). In one embodiment, the auxiliary processor (1023) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (1001) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (1008)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above. The artificial intelligence model can include multiple artificial neural network layers.The artificial neural network may be one of a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-network, or a combination of two or more of the above, but is not limited to the examples described above. In addition to, or alternatively to, a hardware structure, an artificial intelligence model may include a software structure.

[0117] The memory (1030) can store various data used by at least one component (e.g., the processor (1020) or the sensor module (1076)) of the electronic device (1001). The data can include, for example, software (e.g., the program (1040)) and input data or output data for commands related thereto. The memory (1030) can include volatile memory (1032) or non-volatile memory (1034).

[0118] The program (1040) may be stored as software in memory (1030) and may include, for example, an operating system (1042), middleware (1044), or an application (1046).

[0119] The input module (1050) can receive commands or data to be used in a component of the electronic device (1001) (e.g., a processor (1020)) from an external source (e.g., a user) of the electronic device (1001). The input module (1050) can include, for example, a microphone, a mouse, a keyboard, a key (e.g., a button), or a digital pen (e.g., a stylus pen).

[0120] The audio output module (1055) can output audio signals to the outside of the electronic device (1001). The audio output module (1055) can include, for example, a speaker or a receiver. The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

A lens assembly (1110) may include, for example, a wide-angle lens or a telephoto lens.

[0137] The flash (1120) can emit light used to enhance light emitted or reflected from a subject.

The one or more image processing operations may include, for example, depth map generation, 3D modeling, panorama generation, feature extraction, image synthesis, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor (1160) may perform control (e.g., exposure time control, read-out timing control, etc.) on at least one of the components included in the camera module (1080) (e.g., image sensor (1130)). The image processed by the image signal processor (1160) may be stored back in the memory (1150) for further processing or provided to an external component of the camera module (1080) (e.g., memory (1030), display module (1060), electronic device (1002), electronic device (1004), or server (1008)). According to one embodiment, the image signal The processor (1160) may be configured as at least a part of the processor (1020), or may be configured as a separate processor that operates independently of the processor (1020). If the image signal processor (1160) is configured as a separate processor from the processor (1020), at least one image processed by the image signal processor (1160) may be displayed through the display module (1060) as is or after undergoing additional image processing by the processor (1020).

[0140] According to one embodiment, the electronic device (1001) may include a plurality of camera modules (1080), each having different properties or functions. In this case, for example, at least one of the plurality of camera modules (1080) may be a wide-angle camera, and at least another may be a telephoto camera. Similarly, at least one of the plurality of camera modules (1080) may be a front camera, and at least another may be a rear camera.

Referring to FIG. 12, the display module (1060) may include a display (1210) and a display driver IC (DDI) (1230) for controlling the display (1210). The DDI (1230) may include an interface module (1231), a memory (1233) (e.g., a buffer memory), an image processing module (1235), or a mapping module (1237). The DDI (1230) may receive image information including, for example, image data or an image control signal corresponding to a command for controlling the image data, from another component of the electronic device 901 through the interface module (1231). For example, according to one embodiment, image information may be received from a processor (1020) (e.g., a main processor (1021) (e.g., an application processor) or an auxiliary processor (1023) (e.g., a graphics processing unit) that operates independently of the function of the main processor (1021). The DDI (1230) may communicate with a touch circuit (1250) or a sensor module (1076) through the interface module (1231). In addition, the DDI (1230) may store at least a part of the received image information in the memory (1233), for example, in units of frames. The image processing module (1235) may, for example, perform preprocessing or postprocessing (e.g., resolution, brightness, or size adjustment) on at least a part of the image data based on at least a characteristic of the image data or a characteristic of the display (1210). The mapping module (1237) may output a voltage value or a value corresponding to the image data preprocessed or postprocessed through the image processing module (1035).

At least some pixels of the display (1210) may be driven at least in part based on, for example, the voltage values ​​or current values, so that visual information (e.g., text, images, or icons) corresponding to the image data may be displayed through the display (1210).

[0142] According to one embodiment, the display module (1060) may further include a touch circuit (1250). The touch circuit (1250) may include a touch sensor (1251) and a touch sensor IC (1253) for controlling the same. The touch sensor IC (1253) may control the touch sensor (1251) to detect, for example, a touch input or a hovering input for a specific location of the display (1210). For example, the touch sensor IC (1253) may detect a touch input or a hovering input by measuring a change in a signal (e.g., voltage, light quantity, resistance, or charge quantity) for a specific location of the display (1210). The touch sensor IC (1253) may provide information (e.g., location, area, pressure, or time) regarding the detected touch input or hovering input to the processor (1020). According to one embodiment, at least a portion of the touch circuit (1250) (e.g., touch sensor IC (1253)) may be included as part of the display driver IC (1230), or as part of the display (1210), or as part of another component (e.g., auxiliary processor (1023)) disposed external to the display module (1060).

[0143] According to one embodiment, the display module (1060) may further include at least one sensor (e.g., a fingerprint sensor, an iris sensor, a pressure sensor, or an illuminance sensor) of the sensor module (1076), or a control circuit therefor. In this case, the at least one sensor or the control circuit therefor may be embedded in a part of the display module (1060) (e.g., the display (1210) or the DDI (1230)) or a part of the touch circuit (1250). For example, when the sensor module (1076) embedded in the display module (1060) includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may obtain biometric information (e.g., a fingerprint image) associated with a touch input through a part of the display (1210). For another example, if the sensor module (1076) embedded in the display module (1060) includes a pressure sensor, the pressure sensor may obtain pressure information associated with a touch input through a portion or the entire area of ​​the display (1210). According to one embodiment, the touch sensor (1251) or the sensor module (1076) may be disposed between pixels of a pixel layer of the display (1210), or above or below the pixel layer.

[0150] In one embodiment, a method for adjusting the position of a camera relative to a flexible display may be required. According to one embodiment, an electronic device (e.g., the electronic device (101) of FIGS. 1A to 1E and FIGS. 2 to 9, the electronic device (1001) of FIGS. 10 to 12) as described above may include a housing (e.g., the housing (120) of FIGS. 1A to 1E and FIGS. 2 to 9) including a second housing part (e.g., the second housing part (122) of FIGS. 1A to 1E and FIGS. 2 to 9) configured to engage a first housing part (e.g., the first housing part (121) of FIGS. 1A to 1E and FIGS. 2 to 9) so as to be movable between a retracted position and an extended position), and a flexible display (e.g., the flexible display (110) of FIGS. 1A to 1E and FIGS. 2 to 9) coupled to the first housing part and the second housing part. The size of the area of ​​the flexible display visible from the front of the housing can be changed as the housing moves between the retracted position and the extended position. The electronic device can include an actuator within the housing configured to move the second housing part relative to the first housing part (e.g., actuator (220) of FIG. 2), a camera within the housing positioned below the active area of ​​the flexible display (e.g., camera (130) of FIGS. 1A-1E and FIGS. 2-9), and a processor within the housing (e.g., processor (210) of FIG. 2). The active area may include a first area (e.g., the first area (111) of FIGS. 1A to 1E and FIGS. 2 to 9) having a density of pixels of a first density and a second area (e.g., the second area (112) of FIGS. 1A to 1E and FIGS. 2 to 9) surrounding the first area and having a second density higher than the first density.The rear surface of the flexible display, toward which the camera is directed, may include a pattern (e.g., patterns (540, 542, 544) of FIG. 5) arranged along a boundary between the first region and the second region. The processor may be configured to, in response to an input activating the camera, acquire an image (e.g., image (610) of FIG. 6) through the camera. The processor may be configured to identify whether a visual object (e.g., visual object (620) of FIG. 6) corresponding to the pattern is included in the image. The processor may be configured to control the actuator to align the camera with respect to the first region based on the image including the visual object.

[0151] For example, the processor may be configured to obtain a control signal to be transmitted to the one or more motors to align the camera with respect to the first area based on a relationship between rotational angles of the one or more motors included in the actuator and a movement distance of the flexible display with respect to the camera.

[0152] For example, the electronic device may be configured to further include a memory (e.g., memory (215) of FIG. 2) configured to store information indicating a relationship between the rotation angles of the one or more motors and the movement distance. The processor may be configured to change the stored information based on alignment of the camera with respect to the first area.

[0153] For example, the processor may be configured to transmit the control signal, which includes a pulse signal representing a movement distance of the flexible display based on pulse numbers, to the actuator to align the camera with respect to the first area.

[0154] For example, the processor may be configured to, based on controlling the actuator, use the camera to obtain another image to be displayed on the flexible display in response to the input after the camera has moved below the first region.

[0155] For example, the first region may be configured to include a metal layer (e.g., the metal layer (410) of FIG. 4) that includes a plurality of openings (e.g., the plurality of openings (420) of FIG. 4) positioned between the pixels when viewed from the front. The second region may be configured to include a light-shielding layer (e.g., the light-shielding layer (520) of FIG. 5) for reducing reflection of light occurring between the pixels when viewed from the front.

[0156] For example, the processor may be configured to obtain the image representing light reaching the camera through the plurality of apertures in the first region.

[0157] For example, the processor may be configured to determine, based on the visual object within the image, that at least a portion of the camera overlaps the second area when viewed from the front. The processor may be configured to control the actuator to reduce the size of at least a portion of the camera that overlaps the second area.

[0158] According to one embodiment, a method of an electronic device as described above may include an operation of acquiring an image through a camera of the electronic device positioned below an active area of ​​a flexible display of the electronic device (e.g., operation (310) of FIG. 3A), in response to an input activating the camera of the electronic device. The method may include an operation of identifying whether a visual object corresponding to a pattern formed on a rear surface of the flexible display toward which the camera is directed is included in the image (e.g., operation (320) of FIG. 3A). The method may include an operation of controlling the actuator to align the camera with respect to the flexible display based on the image including the visual object (e.g., operation (340) of FIGS. 3A-3B).

[0159] For example, the controlling operation may include obtaining a control signal to be transmitted to the one or more motors to align the camera with respect to the flexible display based on a relationship between rotational angles of the one or more motors included in the actuator and a movement distance of the flexible display with respect to the camera.

[0160] For example, the controlling action may include an action of changing information representing the relationship based on aligning the camera with respect to the flexible display.

[0161] For example, the controlling operation may include transmitting a control signal including a pulse signal representing a movement distance of the flexible display based on a pulse number to the actuator to align the camera.

[0162] For example, the method may further include an operation of, based on controlling the actuator, obtaining another image to be displayed on the flexible display in response to the input using the camera after the camera has moved below the first area.

[0163] For example, the method may include a pattern disposed along a boundary between a first region and a second region of the flexible display, the first region and the second region being distinguished by a density of pixels of the flexible display, on the rear surface of the flexible display toward which the camera is directed.

[0164] For example, the identifying action may include an action of determining, based on the visual object within the image, that at least a portion of the camera overlaps the second area when looking at the front of the flexible display. The controlling action may include an action of controlling the actuator to reduce the size of at least a portion of the camera that overlaps the second area.

The processor may be configured to acquire an image (e.g., an image (610) of FIG. 6) using the camera. The processor may be configured to identify whether a visual object (e.g., a visual object (620) of FIG. 6) associated with a boundary between a first region (e.g., a first region (111) of FIGS. 1A to 1E and FIGS. 2 to 9) and a second region (e.g., a second region (112) of FIGS. 1A to 1E and FIGS. 2 to 9) of the flexible display, which are distinguished by a density of pixels, is included in the image. The processor may be configured to control the actuator to adjust the position based on the image including the visual object.

[0166] For example, the flexible display may be configured to include a pattern formed along the boundary of the first region and the second region on one side of the flexible display toward which the camera is directed.

[0167] For example, the processor may be configured to control the actuator using a location of the visual object within the image based on identifying the visual object corresponding to at least a portion of the pattern.

[0168] For example, the flexible display may be configured to include a first region including pixels positioned based on a first density and a second region including pixels positioned based on a second density exceeding the first density.

[0169] For example, the processor may be configured to control the actuator to move the camera below the first region among the first region and the second region.

[0171] For example, the identifying action may include an action of identifying a visual object corresponding to a pattern formed on the one surface of the flexible display toward which the camera is directed and formed along a boundary between the first region and the second region.

[0172] For example, the controlling action may include controlling the actuator using a location of the visual object within the image based on identifying the visual object corresponding to at least a portion of the pattern.

[0173] For example, the controlling action may include controlling the actuator to move the camera below the first area, between the first area including pixels positioned based on a first density and the second area including pixels positioned based on a second density exceeding the first density.
