Title: Method for providing image and electronic device supporting the same

Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation application, claiming priority under § 365(c), of an International application No. PCT/KR2022/015299, filed on Oct. 11, 2022, which is based on and claims the benefit of a Korean patent application number 10-2021-0151773, filed on Nov. 5, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     The disclosure relates to a method for providing images and an electronic device supporting the same. 
     BACKGROUND ART 
     In line with increasing demands for mobile communication and high levels of integration of electronic devices, the portability of electronic devices, such as mobile communication terminals may be improved, and convenience may be improved in connection with using multimedia functions. For example, displays having integrated touchscreen functions may replace traditional mechanical (button-type) keypads such that electronic devices become compact while maintaining input device functions. 
     It may be more convenient to use electronic devices having larger screen outputs when using web surfing or multimedia functions. Electronic devices may have larger screens to output larger screens but, considering the portability of electronic devices, there may be restrictions on increasing the display size. 
     There has recently been active development regarding flexible displays. Flexible displays may be mounted on electronic devices so as to be slidable, foldable or bendable, or rollable. Electronic devices including flexible displays may provide expanded or reduced screens, depending on the user demands. 
     Meanwhile, electronic devices may display images acquired through cameras, based on the horizontal/vertical ratio of images (hereinafter, referred to as “image aspect ratio”) configured by inputs (for example, user inputs), through displays. For example, if the image aspect ratio is configured to be 1:1 by a user input, an electronic device may process an image acquired through a camera such that the image aspect ratio becomes 1:1, and may display the processed image through a display. 
     The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. 
     DETAILED DESCRIPTION OF THE INVENTION 
     Technical Problem 
     When the image aspect ratio if changed by a user input in an electronic device, the electronic device stops image capture through the camera module and changes the configuration of the camera module (for example, image sensor) so as to correspond to the changed image aspect ratio. After changing the camera module configuration, the electronic device resumes the capture through the camera module based on the changed camera module configuration. For example, if the image aspect ratio is changed from 1:1 to 4:3 by a user input in the electronic device, the electronic device may stop the capture through the camera module and may configure an area corresponding to the image aspect ratio of 4:3, among the entire area of the image sensor, as an area for image acquisition. After configuring the image acquisition area in the image sensor, the electronic device may resume capture using the configure image sensor area. In such a case, there may be a problem in that the screen display through the electronic device becomes temporarily discontinuous because the capture is stopped, the camera module configuration is changed, and the capture is then resumed. 
     In addition, in the case of an electronic device including a display having a fixed size (for example, display providing no expanded or reduced screen), if the image aspect ratio is configured to be a full ratio by an input, an image acquired through a camera is processed such that the horizontal/vertical ratio of the image is identical to the horizontal/vertical ratio of the display (for example, the horizontal/vertical ratio of the display having a fixed size), and the processed image is displayed through the display. For example, in the case of an electronic device including a display having a fixed size, if the image aspect ratio is configured to be a full ratio by an input, the electronic device may acquire information about a predefined display horizontal/vertical ratio. The electronic device may acquire, based on the information about the display horizontal/vertical ratio, an image through an area of an image sensor corresponding to the display horizontal/vertical ratio (for example, an image sensor included in a camera module) (for example, an area configured in the same horizontal/vertical ratio as the display horizontal/vertical ratio among the entire area of the image sensor), and may display the acquired image through the display. 
     However, unlike an electronic device including a display having a fixed size, an electronic device including a flexible display may have difficulty in predefining information regarding the display horizontal/vertical ratio as a result of expansion or reduction of the flexible display. Accordingly, in the case of an electronic device including a flexible display, if the image aspect ratio is configured to be a full ratio by an input, it may be difficult to process an image acquired through a camera such that the image horizontal/vertical ratio is identical to the horizontal/vertical ratio of the display exposed to the outside. 
     Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide a method for providing images and an electronic device supporting the same, wherein in connection with an electronic device including a flexible display, an image having the same horizontal/vertical ratio as the horizontal/vertical ratio of a display exposed to the outside is acquired, and a function related to the image is performed based on the acquired image. 
     Technical issues to be addressed by the disclosure are not limited to the above-mentioned technical issues, and other technical issues not mentioned herein will be clearly understood from the following description by those skilled in the art to which the disclosure pertains. 
     Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments. 
     Technical Solution 
     In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device includes a flexible display in which a region exposed to an outside is reduced as the flexible display is drawn into the electronic device and the region exposed to the outside is expanded as the flexible display is drawn out of the electronic device, a camera module including an image sensor, at least one sensor, and at least one processor electrically connected to the flexible display, the camera module, and the at least one sensor, wherein the at least one processor is configured to acquire an image through the image sensor, identify the region of the flexible display exposed to the outside, through the at least one sensor, determine, within the image, an image part corresponding to the identified region of the flexible display, determine, within the determined image part, a region for performing at least one function related to the image, and perform the at least one function, based on the determined region. 
     In accordance with another aspect of the disclosure, a method for providing an image by an electronic device is provided. The method includes acquiring an image through an image sensor included in a camera module of the electronic device, identifying, through at least one sensor of the electronic device, a region of a flexible display exposed to an outside in the flexible display of the electronic device, the region exposed to the outside being reduced as the flexible display is drawn into the electronic device, and the region exposed to the outside being expanded as the flexible display is drawn out of the electronic device, determining, within the image, an image part corresponding to the identified region of the flexible display, determining, within the determined image part, a region for performing at least one function related to the image, and performing the at least one function, based on the determined region. 
     Advantageous Effects 
     A method for providing images and an electronic device supporting the same, according to various embodiments of the disclosure, are advantageous as follows. In an electronic device including a flexible display, even if the externally exposed area of the flexible display is changed (for example, even during the same is changed) by a movement of the flexible display into or out of the electronic device while a camera module of the electronic device is driven, an image having the same horizontal/vertical ratio as the horizontal/vertical ratio of the externally exposed display is acquired, and a function related to the image is performed based on the acquired image, thereby providing a seamless screen. 
     Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the disclosure.

The communication module  190  may include one or more communication processors that are operable independently from the processor  120  (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module  190  may include a wireless communication module  192  (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module  194  (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device  104  via the first network  198  (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network  199  (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module  192  may identify or authenticate the electronic device  101  in a communication network, such as the first network  198  or the second network  199 , using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module  196 .

     At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)). 
     According to an embodiment, commands or data may be transmitted or received between the electronic device  101  and the external electronic device  104  via the server  108  coupled with the second network  199 . Each of the external electronic devices  102  or  104  may be a device of a same type as, or a different type, from the electronic device  101 . According to an embodiment, all or some of operations to be executed at the electronic device  101  may be executed at one or more of the external electronic devices  102 ,  104 , or  108 . For example, if the electronic device  101  should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device  101 , instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service.

     Various embodiments as set forth herein may be implemented as software (e.g., the program  140 ) including one or more instructions that are stored in a storage medium (e.g., internal memory  136  or external memory  138 ) that is readable by a machine (e.g., the electronic device  101 ). For example, a processor (e.g., the processor  120 ) of the machine (e.g., the electronic device  101 ) may invoke at least one of the one or more instructions stored in the storage medium, and execute it. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium. 
     According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer&#39;s server, a server of the application store, or a relay server. 
     According to various embodiments, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities, and some of the multiple entities may be separately disposed in different components. According to various embodiments, one or more of the above-described components or operations may be omitted, or one or more other components or operations may be added.

In such a case, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. According to various embodiments, operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added. 
       FIG.  2    is a block diagram  200  illustrating a camera module according to an embodiment of the disclosure. 
     Referring to  FIG.  2   , the camera module  180  may include a lens assembly  210 , a flash  220 , an image sensor  230 , an image stabilizer  240 , a memory  250  (e.g., buffer memory), or an image signal processor  260 . 
     The lens assembly  210  may collect light emitted or reflected from an object whose image is to be taken. The lens assembly  210  may include one or more lenses. According to an embodiment, the camera module  180  may include a plurality of lens assemblies  210 . In such a case, the camera module  180  may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies  210  may have the same lens attribute (e.g., view angle, focal length, auto-focusing, f number, or optical zoom), or at least one lens assembly may have one or more lens attributes different from those of another lens assembly. The lens assembly  210  may include, for example, a wide-angle lens or a telephoto lens. 
     The flash  220  may emit light that is used to reinforce light reflected from an object. According to an embodiment, the flash  220  may include one or more light emitting diodes (LEDs) (e.g., a red-green-blue (RGB) LED, a white LED, an infrared (IR) LED, or an ultraviolet (UV) LED) or a xenon lamp. The image sensor  230  may obtain an image corresponding to an object by converting light emitted or reflected from the object and transmitted via the lens assembly  210  into an electrical signal. 
     According to an embodiment, the image sensor  230  may include one selected from image sensors having different attributes, such as a RGB sensor, a black-and-white (BW) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same attribute, or a plurality of image sensors having different attributes. Each image sensor included in the image sensor  230  may be implemented using, for example, a charged coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) sensor. 
     The image stabilizer  240  may move the image sensor  230  or at least one lens included in the lens assembly  210  in a particular direction, or control an operational attribute (e.g., adjust the read-out timing) of the image sensor  230  in response to the movement of the camera module  180  or the electronic device  101  including the camera module  180 . This allows compensating for at least part of a negative effect (e.g., image blurring) by the movement on an image being captured. According to an embodiment, the image stabilizer  240  may sense such a movement by the camera module  180  or the electronic device  101  using a gyro sensor (not shown) or an acceleration sensor (not shown) disposed inside or outside the camera module  180 . According to an embodiment, the image stabilizer  240  may be implemented, for example, as an optical image stabilizer. 
     The memory  250  may store, at least temporarily, at least part of an image obtained via the image sensor  230  for a subsequent image processing task. For example, if image capturing is delayed due to shutter lag or multiple images are quickly captured, a raw image obtained (e.g., a Bayer-patterned image, a high-resolution image) may be stored in the memory  250 , and its corresponding copy image (e.g., a low-resolution image) may be previewed via the display module  160 . Thereafter, if a specified condition is met (e.g., by a user&#39;s input or system command), at least part of the raw image stored in the memory  250  may be obtained and processed, for example, by the image signal processor  260 . According to an embodiment, the memory  250  may be configured as at least part of the memory  130  or as a separate memory that is operated independently from the memory  130 . 
     The image signal processor  260  may perform one or more image processing with respect to an image obtained via the image sensor  230  or an image stored in the memory  250 . The one or more image processing may include, for example, depth map generation, three-dimensional (3D) modeling, panorama generation, feature point extraction, image synthesizing, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor  260  may perform control (e.g., exposure time control or read-out timing control) with respect to at least one (e.g., the image sensor  230 ) of the components included in the camera module  180 . An image processed by the image signal processor  260  may be stored back in the memory  250  for further processing, or may be provided to an external component (e.g., the memory  130 , the display module  160 , the electronic device  102 , the electronic device  104 , or the server  108 ) outside the camera module  180 . According to an embodiment, the image signal processor  260  may be configured as at least part of the processor  120 , or as a separate processor that is operated independently from the processor  120 . If the image signal processor  260  is configured as a separate processor from the processor  120 , at least one image processed by the image signal processor  260  may be displayed, by the processor  120 , via the display module  160  as it is or after being further processed. 
     According to an embodiment, the electronic device  101  may include a plurality of camera modules  180  having different attributes or functions. In such a case, at least one of the plurality of camera modules  180  may form, for example, a wide-angle camera and at least another of the plurality of camera modules  180  may form a telephoto camera. Similarly, at least one of the plurality of camera modules  180  may form, for example, a front camera and at least another of the plurality of camera modules may form a rear camera.

For example, the first structure  301  may be coupled to the second structure  302  in a state of being at least partially surrounded, and slidingly move in a direction parallel to the first surface or the second surface, for example, in a direction (e.g., the X-axis direction or the −X-axis direction) indicated by the arrow {circle around (1)} while being guided by the second structure  302 . 
     According to various embodiments of the disclosure, the second sidewall  323   b  or the third sidewall  323   c  may be omitted. According to an embodiment of the disclosure, the second plate  321   a , the first sidewall  323   a , the second sidewall  323   b , and/or the third sidewall  323   c  may be configured as a separate structure, and thus combined or assembled with each other. The rear plate  321   b  may be coupled to surround at least a part of the second plate  321   a . In some embodiments of the disclosure, the rear plate  321   b  may be configured substantially integrally with the second plate  321   a . According to an embodiment of the disclosure, the second plate  321   a  or the rear plate  321   b  may cover at least a part of the display  303 . For example, the display  303  may be at least partially received in the second structure  302 , and the second plate  321   a  or the rear plate  321   b  may cover a part of the display  303  received in the second structure  302 . 
     According to various embodiments of the disclosure, the first structure  301  is movable in an opened state and a closed state with respect to the second structure  302  in a first direction (e.g., direction {circle around (1)}) parallel to the second plate  321   a  (e.g., the rear case) and the second sidewall  323   b , and may move such that the first structure  301  is placed at a first distance from the first sidewall  323   a  in the closed state and is placed at a second distance greater than the first distance from the first sidewall  323   a  in the opened state. In some embodiments of the disclosure, in a case of a closed state, the first structure  301  may be positioned to surround a part of the first sidewall  323   a.    
     According to various embodiments of the disclosure, the second structure  302  may include at least a part of a non-conductive material (e.g., a polymer material (e.g., plastic), glass, or ceramic). For example, the second structure  302  may be configured by combining a conductive housing and a plate formed of a polymer material. 
     According to various embodiments of the disclosure, the electronic device  101  may include the display  303 , a key input device  341 , a connector hole  343 , audio modules  345   a ,  345   b ,  347   a , and  347   b , or a camera module  349 .

In another embodiment of the disclosure, the electronic device may further include a sensor module, for example, at least one of a gesture sensor, a gyro sensor, an air pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an infrared (IR) sensor, a temperature sensor, a humidity sensor, or an illuminance sensor. 
       FIGS.  4 A and  4 B  are diagrams illustrating an electronic device including a rollable display according to various embodiments of the disclosure. 
     Referring to  FIGS.  4 A and  4 B , in an embodiment of the disclosure, the electronic device  101  may include a rollable display (e.g., a display  420 ) as a flexible display. 
     In an embodiment of the disclosure, the electronic device  101  may include a housing  410 , a display  420 , an opening portion  430  through which the display  420  can be drawn in/out, a roller  440  on which the display  420  can be wound, and a sensor  450 . 
     In an embodiment of the disclosure, the display  420  may be drawn in/out through the opening portion  430  according to rotation of the roller  440 . When the display  420  is drawn in through the opening portion  430 , a display region of the display  420  may be reduced, and when the display  420  is drawn out through the opening portion  430 , a display region of the display  420  may increase. 
     In an embodiment of the disclosure, the rotation of the roller  440  may be performed by a user interaction in which a user pulls or pushes the display  420  (or a member (not shown) for pulling or pushing the display  420 ). However, the disclosure is not limited thereto, and the roller  440  may be rotated by a driving module which drives the roller  440  according to control of the processor  120 . 
     In  FIGS.  4 A and  4 B , the electronic device  101  implemented in a form in which the rollable display  420  is drawn out from the housing  410  (and drawn into the housing  410  in a second direction opposite to a first direction) in the first direction by one roller  440  included in the housing  410  is exemplified, but the disclosure is not limited thereto. For example, the electronic device  101  may be implemented in a form in which the rollable display is drawn out in different directions (e.g., in opposite directions) from the housing included in the electronic device by two or more rollers. 
     Although not shown in  FIGS.  4 A and  4 B , in an embodiment of the disclosure, the electronic device  101  may include a configuration capable of fixing a rolled state of the display  420  and an unfolded state of the display  420 . 
     In an embodiment of the disclosure, when the display  420  is drawn out from the housing  410  or drawn into the housing  410 , according to rotation of the roller  440 , the sensor  450  may detect a region of the display  420  exposed to the outside. For example, the sensor  450  may detect a pattern  451  printed on the display  420 . A pattern  131  may be a QR code, a barcode, a black-and-white pattern, or a color pattern corresponding to a pixel line of the display  420 . As the display  420  is drawn out, a value of the pattern  131  printed on the display  420  may be changed, and the processor  120  may detect a region of the display  420  exposed to the outside according to the changed value of the pattern  131 . For another example, in place of the sensor  450  or in addition to the sensor  450 , the electronic device may detect a region of the display  420  exposed to the outside, through a motion sensor (e.g., an acceleration sensor and/or a gyro sensor) and/or a rotation detection sensor which detects rotation of the roller  440 . However, a method for detecting a region of the display  420  exposed to the outside is not limited to the above-described examples, and more various examples for detecting a region of the display  420  exposed will be described late. 
       FIG.  5    is a block diagram of an electronic device according to an embodiment of the disclosure.

However, the disclosure is not limited thereto, and the display  510  may include all displays in which the size of a region exposed to the outside of the electronic device  101  can be changed. Hereinafter, a region of the display  510  exposed to the outside as the display  510  is drawn into the electronic device  101  or drawn out of the electronic device  101  will be referred to as a “display region of the display”. 
     In an embodiment of the disclosure, the display  510  may be manually or automatically drawn into the electronic device  101  or drawn out of the electronic device  101 . For example, the display  510  may be drawn into the electronic device  101  (e.g., the second structure  302  or the housing  410 ) or drawn out from the electronic device  101  by a user input (e.g., a user&#39;s force of pulling or pushing the first structure  301  or the display  420 ) (e.g., manually) to the first structure  301  or the display  510  (e.g., the display  420 ). For another example, the display  510  may be drawn into the electronic device  101  (e.g., the second structure  302  or the housing  410 ) or drawn out from the electronic device  101 , based on an input (e.g., an icon) to a screen displayed through the display  510  or a physical key input (e.g., automatically). 
     In an embodiment of the disclosure, the camera module  520  may be included in the camera module  180  of  FIGS.  1  and  2   . 
     In an embodiment of the disclosure, the camera module  520  may acquire an image while a display region of the display is expanded or reduced (or in a state in which at least partial region of the display  510  is exposed to the outside). For example, the camera module  520  may continuously (or in real time) acquire multiple images while the display region of the display is expanded or reduced. 
     In an embodiment of the disclosure, the sensor  530  may be configured to identify (e.g., obtain) a display region of the display. 
     In an embodiment of the disclosure, the sensor  530  may include a hall sensor for identifying a display region of the display. For example, when the display  510  is a slidable display as shown in  FIGS.  3 A and  3 B , a plurality of hall sensors may be disposed on the second structure  302 , and a magnet may be disposed on the first structure  301 . As the first structure  301  slidingly moves, a position of the magnet disposed on the first structure  301  may be changed. The plurality of hall sensors disposed on the second structure  302  may detect a magnetic field formed by the magnet and changed according to the position of the magnet. The plurality of hall sensors disposed on the second structure  302  detect a magnetic field formed by the magnet, so that the display region of the display may be identified. 
     In an embodiment of the disclosure, the sensor  530  may include an optical sensor for identifying a display region of the display. For example, when the display  510  is a slidable display as shown in  FIGS.  3 A and  3 B , an optical pattern may be disposed on the second structure  302 , and an optical sensor (e.g., a photo detector) may be disposed on the first structure  301 . As the first structure  301  slidingly moves, a position of the optical sensor disposed on the first structure  301  may be moved. The photo detector detects the optical pattern disposed on the second structure  302 , so that the display region of the display may be identified. 
     In an embodiment of the disclosure, the sensor  530  may include an inertial sensor (also referred to as a “motion sensor”) for identifying a display region of the display. For example, when the display  510  is a slidable display as shown in  FIGS.  3 A and  3 B , acceleration sensors (e.g., 6-axis acceleration sensors) may be disposed in each of the first structure  301  and the second structure  302 . The acceleration sensors acquire information on a relative position (or a change of a position) of the first structure  301  with respect to the second structure  302 , so that the display region of the display may be identified. 
     In an embodiment of the disclosure, the sensor  530  may include a pressure sensor for identifying a display region of the display. For example, when the display  510  is a slidable display as shown in  FIGS.  3 A and  3 B , the pressure sensor may be included in the display  510 . As the first structure  301  slidingly moves with respect to the second structure  302 , a pressure detected in a part forming a curved surface within the display  510  and a pressure detected in a flat part within the display  510  may be different from each other. Based on information on a pressure detected by the pressure sensor, the display region of the display may be identified. 
     In an embodiment of the disclosure, the sensor  530  may include an illuminance sensor for identifying a display region of the display. For example, when the display  510  is a slidable display as shown in  FIGS.  3 A and  3 B , each of a plurality of parts of the display  510  may transmit a different amount of external light (e.g., each of the plurality of parts of the display  510  may be implemented to have a different blocking rate for external light). At least one illuminance sensor disposed on the second structure  302  detects an amount of external light (or a change in an amount of external light) detected by the illuminance sensor as the first structure  301  slidingly moves, so that the display region of the display may be identified. 
     In an embodiment of the disclosure, the sensor  530  may include a rotation angle sensor for identifying a display region of the display. For example, when the display  510  is a slidable display as shown in  FIGS.  3 A and  3 B , at least one rotation angle sensor disposed on the roller (e.g., the roller  830  of  FIG.  8   ) detects an amount of rotation angle (or a change in rotation angle) at which the roller rotates as the first structure  301  slidingly moves, so that the display region of the display may be identified. 
     In an embodiment of the disclosure, although not shown in  FIG.  5   , the electronic device  101  may include devices for identifying a display region of the display in addition to the sensor  530 . For example, when the display  510  is a slidable display as shown in  FIGS.  3 A and  3 B , the first structure  301  may include a mechanical switch element, and the second structure  302  may include a recess or a protrusion which may engage or interfere with the mechanical switch element. While the first structure  301  slidingly moves with respect to the second structure  302 , a position of the recess or protrusion which engages or interferes with the mechanical switch element included in the first structure  301  is identified, so that the display region of the display may be identified. 
     In the above-described examples, when the display  510  is a slidable display as shown in  FIGS.  3 A and  3 B , a method for identifying a display region of the display by the sensor  530  has been described, but the disclosure is not limited thereto. Even when the display  510  is a rollable display as shown in  FIGS.  4 A and  4 B , the sensor  530  may identify a display region of the display in the same or similar manner to the above-described examples. 
     In an embodiment of the disclosure, the memory  540  may be included in the memory  130  of  FIG.  1   .

For example, the electronic device  101  may further include at least one component (e.g., the communication module  190 ) among configurations of the electronic device  101  shown in  FIG.  1   . 
     An electronic device according to various embodiments of the disclosure may include a flexible display in which a region exposed to an outside is reduced as the flexible display is drawn into the electronic device and the region exposed to the outside is expanded as the flexible display is drawn out of the electronic device, a camera module including an image sensor, at least one sensor, and at least one processor electrically connected to the flexible display, the camera module, and the at least one sensor, wherein the at least one processor is configured to acquire an image through the image sensor, identify a region of the flexible display exposed to the outside, through the at least one sensor, determine, within the image, an image part corresponding to the identified region of the flexible display, determine, within the determined image part, a region for performing at least one function related to the image, and perform the at least one function, based on the determined region.

     In various embodiments of the disclosure, the at least one function related to the image may include at least one of an auto focus (AF) function, an auto exposure (AE) function, an auto white balance (AWB) function, a face detection (FD) function, or an object tracking (OT) function.

       FIG.  6    is a flowchart  600  illustrating a method for providing an image according to an embodiment of the disclosure. 
     Referring to  FIG.  6   , in operation  601 , in an embodiment of the disclosure, a processor may acquire an image through an image sensor of a camera module. 
     In an embodiment of the disclosure, the processor  550  may acquire an image through an entire region of an image sensor (e.g., the image sensor  230 ), based on a user input for setting an image aspect ratio (e.g., a horizontal/vertical ratio of an image to be displayed through a display) to a full ratio. 
     In an embodiment of the disclosure, the entire region of the image sensor may refer to all pixels configuring the image sensor or remaining pixels other than some pixels not used for image acquisition among the all pixels configuring the image sensor. 
     In an embodiment of the disclosure, the user input for setting the image aspect ratio to the full ratio may be a user input for displaying an image acquired through the camera module  520  at a horizontal/vertical ratio equal to a horizontal/vertical ratio of a display region (e.g., a region currently exposed to the outside within the display  510 ) of the display. 
     In an embodiment of the disclosure, the user input for setting the image aspect ratio to the full ratio may be a user input for displaying an image acquired through the camera module  520 , through the entire display region of the display, at a horizontal/vertical ratio equal to the horizontal/vertical ratio of the display region of the display (e.g., in a size substantially equal to a size of the display region of the display). 
       FIG.  7    is a diagram  700  illustrating a method for setting an image aspect ratio to a full ratio according to an embodiment of the disclosure. 
     Referring to  FIG.  7   , in an embodiment of the disclosure, the processor  550  may display information for setting an image aspect ratio, through the display  510 , while a camera application is being executed. For example, as shown in  FIG.  7   , the processor  550  may display, through the display  510 , objects  711 ,  712 , and  713  for setting a plurality of specified image aspect ratios as image aspect ratios, and an object  720  for setting a full ratio as an image aspect ratio. 
     In an embodiment of the disclosure, the plurality of specified image aspect ratios may refer to image aspect ratios (e.g., image aspect ratios of 4:3, 16:9, and 1:1) configured to display an image at a fixed ratio, regardless of a change in a display region of the display  510 . 
     In an embodiment of the disclosure, although an object for setting a full ratio as an image aspect ratio in  FIG.  7    is exemplified as being displayed as text, such as “full”, the disclosure is not limited thereto. For example, the processor  550  may display, through the display  510 , text representing a horizontal/vertical ratio of a display region (a region of the display currently exposed to the outside) of the display, as the object for setting the full ratio as the image aspect ratio. 
     In an embodiment of the disclosure, the processor  550  may set the image aspect ratio to the full ratio, based on a user input to the object  720  for setting the full ratio as the image aspect ratio. 
     Referring to  FIG.  6   , in operation  603 , in an embodiment of the disclosure, the processor  550  may identify a region (a display region of the display) of the display  510  exposed to the outside of the electronic device  101 , through the sensor  530 . A method for identifying a display region of the display by the processor  550  through the sensor  530  will be described with reference to  FIG.  8    below. 
       FIG.  8    is a diagram  800  illustrating a method for identifying a region of a display exposed to the outside according to an embodiment of the disclosure. 
     Referring to  FIG.  8   , in an embodiment of the disclosure, reference numeral  801  may denote the electronic device  101  including a slidable display in which at least a part of the display  510  is in a state of being exposed to the outside (in an opened state). In an embodiment of the disclosure, the processor  550  may identify a vertical length h of a display region of the display  510  which is changed as the first structure  301  slidingly moves on the second structure  302 . 
     In an embodiment of the disclosure, the processor  550  may identify a vertical length h of a display region of the display which is changed as the first structure  301  slidingly moves on the second structure  302 , through a hall sensor. For example, a plurality of hall sensors may be disposed on the second structure  302 , and a magnet may be disposed on the first structure  301 . As the first structure  301  slidingly moves, a position of the magnet disposed on the first structure  301  may be changed. The plurality of hall sensors disposed on the second structure  302  may detect a magnetic field formed by the magnet and changed according to the position of the magnet. The plurality of hall sensors disposed on the second structure  302  detect a magnetic field formed by the magnet, so that the processor  550  may identify the vertical length h of the display region of the display  510 . 
     In an embodiment of the disclosure, the processor  550  may identify a vertical length h of a display region of the display  510  which is changed as the first structure  301  slidingly moves on the second structure  302 , through an optical sensor. For example, an optical pattern may be disposed on the second structure  302  and an optical sensor (e.g., a photo detector) may be disposed on the first structure  301 . As the first structure  301  slidingly moves, a position of the optical sensor disposed on the first structure  301  may be moved. The photo detector detects the optical pattern disposed on the second structure  302 , so that the processor  550  may identify the vertical length h of the display region of the display  510 . 
     In an embodiment of the disclosure, the processor  550  may identify a vertical length h of a display region of the display  510  which is changed as the first structure  301  slidingly moves on the second structure  302 , through an inertial sensor. For example, acceleration sensors (e.g., 6-axis acceleration sensors) may be disposed in each of the first structure  301  and the second structure  302 . The acceleration sensors acquire information on a relative position (or a change of a position) of the first structure  301  with respect to the second structure  302 , so that the processor  550  may identify the vertical length h of the display region of the display  510 . 
     In an embodiment of the disclosure, the processor  550  may identify a vertical length h of a display region of the display  510  which is changed as the first structure  301  slidingly moves on the second structure  302 , through a pressure sensor. For example, the pressure sensor may be included in the display  510 . As the first structure  301  slidingly moves with respect to the second structure  302 , a pressure detected in a part forming a curved surface within the display  510  and a pressure detected in a flat part within the display  510  may be different from each other. Based on information on a pressure detected by the pressure sensor, the processor  550  may identify the vertical length h of the display region of the display  510 . 
     In an embodiment of the disclosure, the processor  550  may identify a vertical length h of a display region of the display  510  which is changed as the first structure  301  slidingly moves on the second structure  302 , through an illuminance sensor. For example, each of a plurality of parts of the display  510  may transmit a different amount of external light (e.g., each of the plurality of parts of the display  510  may be implemented to have a different blocking rate for external light). At least one illuminance sensor disposed on the second structure  302  detects an amount of external light (or a change in an amount of external light) detected by the illuminance sensor as the first structure  301  slidingly moves, so that the processor  550  may identify the vertical length h of the display region of the display  510 . 
     In an embodiment of the disclosure, the processor  550  may identify a vertical length h of a display region of the display  510  which is changed as the first structure  301  slidingly moves on the second structure  302 , through a rotation angle sensor. For example, at least one rotation angle sensor disposed on a roller  830  may detect an amount of rotation angle (or a change in rotation angle) at which the roller  830  rotates as the first structure  301  slidingly moves. Based on information on the amount of the rotation angle, the processor  550  may identify the vertical length h of the display region of the display  510 . 
     In an embodiment of the disclosure, although not shown in  FIG.  8   , the electronic device  101  may include devices for identifying a display region of the display in addition to the sensor  530 . For example, the first structure  301  may include a mechanical switch element, and the second structure  302  may include a recess or a protrusion which may engage or interfere with the mechanical switch element. While the first structure  301  slidingly moves with respect to the second structure  302 , a position of the recess or protrusion which engages or interferes with the mechanical switch element included in the first structure  301  is identified, so that the processor  550  may identify a vertical length h of a display region of the display  510 . 
     In an embodiment of the disclosure, the processor  550  may identify a display region of the display  510 , based on a vertical length h of the display region of the display  510  and a horizontal length w of the display region of the display. For example, at reference numeral  802 , the processor  550  identifies a vertical length h of a display region of the display  510  and a horizontal length w of the display region of the display, so that the display region of the display  510  (e.g., a horizontal/vertical ratio of the display region of the display and/or a size of the display region of the display) may be identified (e.g., obtained). 
     In  FIG.  8   , although a method for identifying a display region of the display when the display  510  is a slidable display has been described, even when the display  510  is a rollable display, the processor  550  may identify a display region of the display  510  by using the same or similar manner to the examples described with reference to  FIG.  8   . 
     Referring to  FIG.  6   , in operation  605 , in an embodiment of the disclosure, the processor  550  may determine an image part (hereinafter, used interchangeably with a “first image part”) corresponding to the identified region (a display region of the display) of the display  510  within an image. 
     In an embodiment of the disclosure, the processor  550  may determine a first image part corresponding to a display region of the display, within an image (hereinafter, used interchangeably with an “entire image region”) acquired through the entire region of the image sensor. For example, the processor  550  (e.g., an application processor or the image signal processor  260 ) may determine, in the entire image region, as the first image part corresponding to the display region of the display, a region having a horizontal/vertical ratio equal to a horizontal/vertical ratio of the display region of the display, with reference to the center of the entire image region. For another example, the processor  550  may determine, as the first image part corresponding to the display region of the display, a region which includes a boundary line in a direction opposite to a direction in which the display region of the display is expanded with reference to the center of the entire image region (a boundary line in a direction in which the display region of the display is reduced) among boundary lines of the entire image region in the entire image region, and has a horizontal/vertical ratio equal to the horizontal/vertical ratio of the display region of the display. For another example, the processor  550  may determine, as the first image part corresponding to the display region of the display, a region which includes a boundary line in the same direction as a direction in which the display region of the display is expanded with reference to the center of the entire image region (or a boundary line in the opposite direction to a direction in which the display region of the display is reduced) among boundary lines of the entire image region in the entire image region, and has a horizontal/vertical ratio equal to the horizontal/vertical ratio of the display region of the display. However, a method for determining a first image part corresponding to a display region of the display is not limited to the above-described examples. 
     In an embodiment of the disclosure, the processor  550  may determine, based on a zoom ratio associated with a camera, a first image part corresponding to the identified region of the display  510  (a display region of the display) within the image. For example, the processor  550  may determine the first image part corresponding to the display region of the display, in the entire image region, based on a horizontal/vertical ratio of the display region of the display and a currently set zoom ratio of the camera. 
     Referring to  FIG.  6   , in operation  607 , in an embodiment of the disclosure, the processor  550  may determine a region (hereinafter, referred to as a “region of interest”) for performing at least one function related to an image, within the first image part corresponding to the display region of the display. 
     In an embodiment of the disclosure, the at least one function related to the image may include at least one of an auto focus (AF) function, an auto exposure (AE) function, an auto white balance (AWB) function, a face detection (FD) function, or an object tracking (OT) function. 
     Referring to  FIG.  6   , in operation  609 , in an embodiment of the disclosure, the processor  550  may perform the at least one function related to the image, based on the region (the region of interest) for performing the at least one function related to the image. 
     Hereinafter, with reference to  FIGS.  9 ,  10 A,  10 B,  11 , and  12   , a method for determining a region of interest for at least one function related to an image, and performing the at least one function related to the image based on the determined region of interest will be described. 
       FIG.  9    is a diagram  900  illustrating a method for determining a region of interest for an AF function according to an embodiment of the disclosure. 
       FIGS.  10 A and  10 B  are diagrams  1000   a  and  1000   b  illustrating a method for determining a region of interest for an AF function according to various embodiments of the disclosure. 
     Referring to  FIGS.  9 ,  10 A, and  10 B , in an embodiment of the disclosure, the processor  550  may determine a region of interest for an AF function within a first image part corresponding to a display region of a display. For example, the processor  550  may determine, within the first image part, a region specified by a user input, a region in which a face is detected, or a screen center region as the region of interest for the AF function. 
     In an embodiment of the disclosure, the processor  550  may determine the region specified by the user input as the region of interest for the AF function. For example, the processor  550  may identify a position touched by a user (e.g., a user&#39;s finger or an electronic pen) within the first image part. The processor  550  may determine, within the first image part, as the region of interest for the AF function, a region (e.g., a region centered on the touched position and having an area corresponding to about 1/10 of an area of the display region (or the first image part) of the display) having a specified area with reference to the touched position. For another example, when at least a part of the region touched by the user within the first image part overlaps a region including an object within the first image part, the processor  550  may determine the region including the object within the first image part, as the region of interest for the AF function. In an embodiment of the disclosure, after the region including the object within the first image part is determined as the region of interest for the AF function, the processor  550  may track a moving object within the first image part. The processor  550  may track the object so as to determine, as the region of interest for the AF function, a region including the moving object within the first image part. 
     In an embodiment of the disclosure, the processor  550  may determine the region in which the face is detected, as the region of interest for the AF function. For example, the processor  550  may detect a face within the first image part by using a face detection algorithm. The processor  550  may determine the region in which the face is detected (e.g., a region including a face), within the first image part, as the region of interest for the AF function. 
     In an embodiment of the disclosure, the processor  550  may determine the screen center region as the region of interest for the AF function. In an embodiment of the disclosure, the processor  550  may obtain a center of the first image part. The processor  550  may determine, within the first image part, as the region of interest for the AF function, a region (e.g., a region having an area corresponding to about 1/10 of an area of the display region (or the first image part) of the display with reference to the center of the first image part) having a specified area with reference to the center of the first image part. For example, reference numerals  901 ,  902 , and  903  of  FIG.  9    may sequentially indicate first image parts determined when the display  510  is drawn into the electronic device  101  in a state in which the display is maximally drawn out of the electronic device  101  (e.g., when the display  510  is drawn into the electronic device  101  in the −X axis direction). As shown by reference numeral  901  of  FIG.  9   , when a horizontal/vertical ratio of the display region of the display is 1:1, the processor  550  may determine, as the region of interest for the AF function, a region  911  having a specified area with reference to the center of a first image part  910  corresponding to the display region of the display. As shown by reference numeral  902  of  FIG.  9   , when a horizontal/vertical ratio of the display region of the display is 4:3, the processor  550  may determine, as the region of interest for the AF function, a region  921  having a specified area with reference to the center of a first image part  920  corresponding to the display region of the display. As shown by reference numeral  903  of  FIG.  9   , when a horizontal/vertical ratio of the display region of the display is 16:9, the processor  550  may determine, as the region of interest for the AF function, a region  931  having a specified area with reference to the center of a first image part  930  corresponding to the display region of the display. In an embodiment of the disclosure, as shown by reference numerals  901  to  903 , when an area of the first image part is reduced, the processor  550  may determine, as the region of interest for the AF function, a region having the reduced area with reference to the center of the first image part, so as to correspond to (e.g., be proportional to) the reduced area of the first image part. However, the disclosure is not limited thereto, and even when the area of the first image part is reduced, the processor  550  may determine a region having a fixed area with reference to the center of the first image part as the region of interest for the AF function. 
     In an embodiment of the disclosure, the processor  550  may set a priority between the region specified by the user input, the region in which the face is detected, and the screen center region, in order to determine the region of interest for the AF function. 
     In an embodiment of the disclosure, in order to determine the region of interest for the AF function, the processor  550  may set a first priority (e.g., a highest priority) to the region specified by the user input, a second priority to the region in which the face is detected, and a third priority (e.g., a lowest priority) to the screen center region. When the first image part includes at least two of the regions specified by the user input, the region in which the face is detected, and the screen center region, the processor  550  may determine the region of interest for the AF function, based on the priority. 
     For example, reference numerals  1001 ,  1002 , and  1003  of  FIG.  10 A  may be diagrams sequentially illustrating a method for determining a region of interest for an AF function, based on a priority, when the display  510  is drawn into the electronic device  101  in a state in which the display is maximally drawn out of the electronic device  101  (e.g., when the display  510  is drawn into the electronic device  101  in the −X axis direction). In  FIG.  10 A , a first image part may be a region having a horizontal/vertical ratio equal to a horizontal/vertical ratio of a display region of the display, with reference to the center of an entire image region (e.g., an image acquired through the entire region of the image sensor), in the entire image region. As shown by reference numeral  1001  of  FIG.  10 A , when the horizontal/vertical ratio of the display region of the display is 1:1, the processor  550  may determine a first image part  1010  corresponding to the display region of the display. When a face  1041  is detected within the first image part  1010  and a user input for specifying a region of interest for an AF function is not received, the processor  550  may determine a region  1011  (e.g., a region including the face  1041 ) in which the face  1041  is detected, as the region of interest for the AF function, preferentially to a region having a specified area with reference to the center of the first image part  1010 . As shown by reference numeral  1002  of  FIG.  10 A , when the horizontal/vertical ratio of the display region of the display is 4:3, the processor  550  may determine a first image part  1020  corresponding to the display region of the display. When a face  1042  is detected within the first image part  1020  and a user input for specifying a region of interest for an AF function is not received, the processor  550  may determine a region  1021  (e.g., a region including the face  1042 ) in which the face  1042  is detected, as the region of interest for the AF function, preferentially to a region having a specified area with reference to the center of the first image part  1020 . As shown by reference numeral  1003  of  FIG.  10 A , when the horizontal/vertical ratio of the display region of the display is 16:9, the processor  550  may determine a first image part  1030  corresponding to the display region of the display. When a face is not detected within the first image part  1030  and a user input for specifying a region of interest for an AF function is not received, the processor  550  may determine a region  1031  having a specified area with reference to a center  1043  of the first image part  1030  as the region of interest for the AF function. 
     For another example, reference numerals  1004 ,  1005 , and  1006  of  FIG.  10 B  may be diagrams sequentially illustrating a method for determining a region of interest for an AF function, based on a priority, when the display  510  is drawn into the electronic device  101  in a state in which the display is maximally drawn out of the electronic device  101  (e.g., when the display  510  is drawn into the electronic device  101  in the −X axis direction). In  FIG.  10 B , a first image part may be a region which includes a boundary line in a direction in which a display region of the display is reduced with reference the center of an entire image region among boundary lines of the entire image region in the entire image region, and has a horizontal/vertical ratio equal to a horizontal/vertical ratio of the display region of the display. As shown by reference numeral  1004  of  FIG.  10 B , when the horizontal/vertical ratio of the display region of the display is 1:1, the processor  550  may determine the first image part  1010  corresponding to the display region of the display. When a face  1044  is detected within the first image part  1010  and a user input for specifying a region of interest for an AF function is not received, the processor  550  may determine a region  1051  (e.g., a region including the face  1044 ) in which the face  1044  is detected, as the region of interest for the AF function, preferentially to a region having a specified area with reference to the center of the first image part  1010 . As shown by reference numeral  1005  of  FIG.  10 B , when the horizontal/vertical ratio of the display region of the display is 4:3, the processor  550  may determine a first image part  1050  corresponding to the display region of the display. When a face  1045  is detected within the first image part  1050  and a user input for specifying a region of interest for an AF function is not received, the processor  550  may determine a region  1061  (e.g., a region including the face  1045 ) in which the face  1045  is detected, as the region of interest for the AF function, preferentially to a region having a specified area with reference to the center of the first image part  1050 . As shown by reference numeral  1006  of  FIG.  10 B , when the horizontal/vertical ratio of the display region of the display is 16:9, the processor may determine a first image part  1060  corresponding to the display region of the display. When a face  1046  is detected within the first image part  1060  and a user input for specifying a region of interest for an AF function is not received, the processor may determine a region  1071  (e.g., a region including the face  1046 ) in which the face  1046  is detected, as the region of interest for the AF function, preferentially to a region having a specified area with reference to the center of the first image part  1060 . 
     In an embodiment of the disclosure, when a region of interest for an AF function is determined, the processor  550  may perform the AF function, based on the region of interest for the AF function. For example, the processor  550  may configure (e.g., adjust a position of a lens for focus) a camera setting, based on a distance between the camera module  180  and a subject (e.g., a person and/or an object) which is an object of the region of interest for the AF function. However, a method for performing an AF function based on a region of interest for the AF function is not limited to the above-described example. When a camera setting is set, the processor  550  may acquire an image through the camera module  180  according to the set camera setting. 
       FIG.  11    is a diagram  1100  illustrating a method for determining a region of interest for an AE function according to an embodiment of the disclosure. 
     Referring to  FIG.  11   , in an embodiment of the disclosure, the processor  550  may determine a region of interest for an auto exposure (AE) function within a first image part corresponding to a display region of a display. 
     In an embodiment of the disclosure, the processor  550  may determine a region substantially equal to the first image part as the region of interest for the AE function. For example, the processor  550  may determine, as the region of interest for the AE function, a part equal to the first image part or a remaining part other than an outermost part (e.g., an edge part of the first image part) of the first image part within the first image part. Reference numerals  1101 ,  1102 , and  1103  of  FIG.  11    may sequentially indicate first image parts determined when the display  510  is drawn into the electronic device  101  in a state in which the display is maximally drawn out of the electronic device  101  (e.g., when the display  510  is drawn into the electronic device  101  in the −X axis direction). As shown by reference numeral  1101  of  FIG.  11   , when a horizontal/vertical ratio of the display region of the display is 1:1, the processor  550  may determine, as the region of interest for the AE function, a region  1111  (e.g., a region other than an outermost part of a first image part  1110  within the first image part  1110 ) substantially equal to the first image part  1110  corresponding to the display region of the display. As shown by reference numeral  1102  of  FIG.  11   , when the horizontal/vertical ratio of the display region of the display is 4:3, the processor  550  may determine, as the region of interest for the AE function, a region  1121  substantially equal to a first image part  1120  corresponding to the display region of the display. As shown by reference numeral  1103  of  FIG.  11   , when the horizontal/vertical ratio of the display region of the display is 16:9, the processor  550  may determine, as the region of interest for the AE function, a region  1131  substantially equal to a first image part  1130  corresponding to the display region of the display. 
     In an embodiment of the disclosure, when the region of interest for the AE function is determined, the processor  550  may perform the AF function, based on the region of interest for the AE function. 
     In an embodiment of the disclosure, the processor  550  may set a weight for the AE function with respect to the region of interest. In an embodiment of the disclosure, the processor  550  may set (e.g., assign) different weights with respect to a region specified by a user input, a region in which a face is detected, a screen center region, and a background region, within the region of interest. For example, when a region of interest (e.g., a region of interest  1111 , a region of interest  1121 , or a region of interest  1131 ) is set to be divided into a plurality of sub-regions (e.g., a plurality of sub-regions in the form of a grid) as shown in  FIG.  11   , the processor  550  may assign a high weight in the order of first sub-regions including a region specified by a user input, second sub-regions including a region in which a face is detected, third sub-regions including a screen center region, and fourth sub-regions including a background region.  FIG.  11    illustrates that the number of the plurality of sub-regions is reduced as an area of the first image part is reduced, but the disclosure is not limited thereto. For example, as an area of the first image part is reduced, the number of the plurality of sub-regions may be maintained, and an area of each of the plurality of sub-regions may be reduced to correspond to the reduction in the area of the first image part. 
     In an embodiment of the disclosure, the processor  550  may perform the AE function, based on a weight set for the region of interest. For example, the processor  550  may set a camera setting for exposure (e.g., adjust an exposure time and/or camera sensitivity (international organization for standardization (ISO)), within the region of interest, based on brightness information of the first sub-regions to which a first weight (e.g., the highest weight) is set, brightness information of the second sub-regions to which a second weight (e.g., the second highest weight) is set, brightness information of the third sub-regions to which a third weight (e.g., the third highest weight) is set, and brightness information of the fourth sub-regions to which a fourth weight (e.g., the lowest weight) is set. However, a method for performing an AE function based on a region of interest is not limited to the above-described example. When a camera setting is set, the processor  550  may acquire an image through the camera module  180  according to the set camera setting. 
       FIG.  12    is a diagram  1200  illustrating a method for determining a region of interest for an AWB function according to an embodiment of the disclosure. 
     Referring to  FIG.  12   , in an embodiment of the disclosure, the processor  550  may determine a region of interest for an auto white balance (AWB) function within a first image part corresponding to a display region of a display. 
     In an embodiment of the disclosure, the processor  550  may determine a region substantially equal to the first image part as the region of interest for the AWB function. For example, the processor  550  may determine, as the region of interest for the AWB function, a part equal to the first image part or a remaining part other than an outermost part (e.g., an edge part of the first image part) of the first image part within the first image part. Reference numerals  1201 ,  1202 , and  1203  of  FIG.  12    may sequentially indicate first image parts determined when the display  510  is drawn into the electronic device  101  in a state in which the display is maximally drawn out of the electronic device  101  (e.g., when the display  510  is drawn into the electronic device  101  in the −X axis direction). As shown by reference numeral  1201  of  FIG.  12   , when a horizontal/vertical ratio of the display region of the display is 1:1, the processor  550  may determine, as the region of interest for the AWB function, a region  1211  (e.g., a region other than an outermost part of a first image part  1210  within the first image part  1210 ) substantially equal to the first image part  1210  corresponding to the display region of the display. As shown by reference numeral  1202  of  FIG.  12   , when the horizontal/vertical ratio of the display region of the display is 4:3, the processor  550  may determine, as the region of interest for the AWB function, a region  1221  substantially equal to a first image part  1220  corresponding to the display region of the display. As shown by reference numeral  1203  of  FIG.  12   , when the horizontal/vertical ratio of the display region of the display is 16:9, the processor  550  may determine, as the region of interest for the AWB function, a region  1231  substantially equal to a first image part  1230  corresponding to the display region of the display. 
     In an embodiment of the disclosure, when the region of interest for the AWB function is determined, the processor  550  may perform the AWB function, based on the region of interest for the AWB function. For example, when a region of interest (e.g., a region of interest  1211 , a region of interest  1221 , or a region of interest  1231 ) is set to be divided into a plurality of sub-regions as shown in  FIG.  12   , the processor  550  may identify sub-regions having an achromatic color among the plurality of sub-regions, based on color information of each of the plurality of sub-regions. The processor  550  may acquire a gain (e.g., an R gain and a B gain) for setting white balance of a first image part, based on color information of the sub-regions having an achromatic color. The processor  550  may adjust (or maintain) white balance for the first image part, based on the acquired gain. 
     In the above-described examples, the AF function, the AE function, and the AWB function are exemplified as at least one function related to an image, but the disclosure is not limited thereto. In an embodiment of the disclosure, the processor  550  may determine, within a first image part corresponding to a display region of the display, a region of interest for performing a face detection (FD) function and/or an object tracking (OT) function, and perform the FD function and/or the OT function within the determined region of interest. 
     In an embodiment of the disclosure, the processor  550  may perform the at least one function related to the image, and then display the image through the display  510 . For example, when a camera setting is set as the AF function and/or the AE function is performed, the processor  550  may acquire an image through the camera module  520 , based on the set camera setting. The processor  550  may display, through the display  510 , the first image part corresponding to the display region of the display within the acquired image. For another example, the processor  550  may display, through the display  510 , a first image part (e.g., an image corrected by performing the AWB function on the first image part) acquired by performing the AWB function. 
     In an embodiment of the disclosure, the processor  550  may store the first image part displayed through the display  510  in the memory  540 , based on a user input (e.g., a user input for capturing an image). 
       FIG.  13    is a flowchart  1300  illustrating a method for providing an image according to an embodiment of the disclosure. 
     Referring to  FIG.  13   , in operation  1301 , in an embodiment of the disclosure, the processor  550  may acquire an image through an image sensor (e.g., the image sensor  230 ) of the camera module  520 . 
     At least a part of operation  1301  is the same as or similar to at least a part of operation  601  of  FIG.  6   , and thus a detailed description thereof will be omitted. 
     In operation  1303 , in an embodiment of the disclosure, the processor  550  may identify a region (a display region of a display) of the display exposed to the outside of the electronic device  101 , through the sensor  530 . 
     At least a part of operation  1303  is the same as or similar to at least a part of operation  603  of  FIG.  6   , and thus a detailed description thereof will be omitted. 
     In operation  1305 , in an embodiment of the disclosure, the processor  550  may determine an image part (a first image part) corresponding to the identified region (the display region of the display) of the display within the image. 
     At least a part of operation  1305  is the same as or similar to at least a part of operation  605  of  FIG.  6   , and thus a detailed description thereof will be omitted. 
     In operation  1307 , in an embodiment of the disclosure, the processor  550  may determine whether the region (the display region of the display) of the display is changed by a threshold region or more. For example, the processor  550  may determine whether an amount of change in the region exposed to the outside (or an amount of change in a vertical length h of the display region of the display  510 ) has been changed by the threshold region or more as the display  550  is drawn into the electronic device  101  or drawn out of the electronic device  101 . 
     When it is determined in operation  1307  that the display region of the display is changed by the threshold region or more, in operation  1309 , in an embodiment of the disclosure, the processor  550  may determine a region (a region of interest) for performing at least one function related to the image within the first image part corresponding to the display region of the display. 
     At least a part of operation  1309  is the same as or similar to at least a part of operation  607  of  FIG.  6   , and thus a detailed description thereof will be omitted. 
     In operation  1311 , in an embodiment of the disclosure, the processor  550  may perform the at least one function related to the image, based on the region (the region of interest) for performing the at least one function related to the image. 
     At least a part of operation  1311  is the same as or similar to at least a part of operation  609  of  FIG.  6   , and thus a detailed description thereof will be omitted. 
     When it is determined in operation  1307  that the display region of the display is not changed by the threshold region or more, in operation  1313 , in an embodiment of the disclosure, the processor  550  may maintain the previously determined region (the region of interest) for performing the at least one function related to the image. For example, the processor  550  may maintain (or determine) the region of interest for performing the at least one function related to the image, which has been determined before changing the display region of the display, as the region of interest for performing the at least one function related to the image after changing the display region of the display. 
     In operation  1307 , when the previously determined region of interest for performing the at least one function related to the image is maintained, in operation  1311 , in an embodiment of the disclosure, the processor  550  may perform the at least one function related to the image, based on the maintained region of interest. 
     In an embodiment of the disclosure, the processor  550  determines (e.g., re-sets) the region of interest for performing the at least one function related to the image only when the display region of the display is changed by the threshold region or more, so that power consumed to perform an image-providing operation may be reduced, and a resource for performing the image-providing operation may be saved. 
       FIG.  14    is a diagram  1400  illustrating a method for providing an image according to an embodiment of the disclosure. 
     Referring to  FIG.  14   , in an embodiment of the disclosure, when an image aspect ratio is set to a full ratio, the processor  550  may display an entire image acquired from an image sensor (e.g., the entire region of the image sensor) through the display  510 . When the entire image is displayed, the processor  550  may control the display  510  such that a first image part corresponding to a display region of the display is distinguished from a region other than the first image part in the entire image. For example, when the image aspect ratio is set to the full ratio, the processor  550  may acquire an image from the entire region of the image sensor. The processor  550  may identify the first image part corresponding to the display region of the display within the acquired image. The processor  550  may control the display  510  such that when the acquired image is displayed, a region other than the first image part within the acquired image is displayed darker than the first image part. However, a method for controlling the display  510  such that a first image part is distinguished from a region other than the first image part in an entire image is not limited to the example of controlling the display  510  such that the region other than the first image part within the acquired image is displayed darker than the first image part. 
     In an embodiment of the disclosure, reference numerals  1401 ,  1402 , and  1403  of  FIG.  14    may sequentially indicate images displayed through the display  510  when the display  510  is drawn into the electronic device  101  in a state in which the display is maximally drawn out of the electronic device  101  and the image aspect ratio is set to the full ratio. As shown by reference numeral  1401 , when a horizontal/vertical ratio of the display region of the display is 1:1 and a horizontal/vertical ratio of an image acquired through the image sensor is 1:1, the processor  550  may display an image  1410  acquired through the image sensor, through the display  510 . As shown by reference numeral  1402 , when the horizontal/vertical ratio of the display region of the display is 4:3, the processor  550  may display an image  1420  acquired through the image sensor, through the display  510 . The processor  550  may control the display  510  such that when the image  1420  is displayed, a region  1451  other than a first image part  1471  corresponding to the display region of the display within the image  1420  is displayed darker than the first image part  1471 . As shown by reference numeral  1403 , when the horizontal/vertical ratio of the display region of the display is 16:9, the processor  550  may display an image  1430  acquired through the image sensor, through the display  510 . The processor  550  may control the display  510  such that when the image  1430  is displayed, a region  1461  other than a first image part  1481  corresponding to the display region of the display within the image  1430  is displayed darker than the first image part  1481 . 
     In an embodiment of the disclosure, reference numerals  1491 ,  1492 , and  1493  may indicate objects for capturing an image. In an embodiment of the disclosure, when a user input for an object for capturing an image is received, the processor  550  may store a first image part (e.g., the first image part  1410 , the first image part  1420 , or the first image part  1430 ) in the memory  540 . 
     Although not described above, in an embodiment of the disclosure, when the display  510  is drawn out of the electronic device  101  or drawn into the electronic device  101  in the same or similar manner as described with reference to  FIGS.  6 ,  7 ,  8 ,  9 ,  10 A,  10 B,  11 ,  12 , and  13   , the processor  550  may determine a first image part corresponding to a display region of the display, and determine a region of interest (e.g., regions of interest  1411 ,  1421 , and  1431  for an AF function) for performing at least one function related to an image within the first image part. 
     In an embodiment of the disclosure, when an entire image acquired from an image sensor (e.g., the entire region of the image sensor) is displayed, the processor  550  may control the display  510  such that the first image part corresponding to the display region of the display is distinguished from a region other than the first image part in the entire image, so as to provide, to a user, information on an image region to be stored in the memory  540  by image capturing, and enable the user to set a better composition or image aspect ratio. 
     A method for providing an image by an electronic device according to various embodiments of the disclosure may include acquiring an image through an image sensor included in a camera module of the electronic device, identifying, through at least one sensor of the electronic device, a region of a flexible display exposed to the outside in the flexible display of the electronic device, the region exposed to the outside being reduced as the flexible display is drawn into the electronic device, and the region exposed to the outside being expanded as the flexible display is drawn out of the electronic device, determining, within the image, an image part corresponding to the identified region of the flexible display, determining, within the determined image part, a region for performing at least one function related to the image, and performing the at least one function, based on the determined region. 
     In various embodiments of the disclosure, the acquiring of the image may include acquiring the image through an entire region of the image sensor, based on a user input for setting an image aspect ratio to a full ratio. 
     In various embodiments of the disclosure, the identifying of the region of the flexible display may include identifying a horizontal/vertical ratio of the region of the flexible display exposed to the outside, and the determining of the image part may include determining, within the image, as the image part, a region having a horizontal/vertical ratio equal to the horizontal/vertical ratio of the region of the flexible display, with reference to a center of the image. 
     In various embodiments of the disclosure, the at least one function related to the image may include at least one of an AF function, an AE function, an AWB function, a FD function, or an OT function. 
     In various embodiments of the disclosure, the determining of the region for performing the at least one function related to the image may include determining, when the function related to the image includes the AF function, within the determined image part, a region specified by a user input, a region in which a face is detected, or a screen center region, as a region of interest for the AF function.
