The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. 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 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 cellular 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 and 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.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190

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 electronic devices 102 and 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. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

According to various embodiments, the processor 120 of the electronic device 101 may perform control to: generate a user avatar based on a selfie image designated by a user; reprocess the user avatar to generate a custom object linked to applications of the electronic device; and when an application of the electronic device 101 is executed, output the custom object to an application execution screen in response to a user request.

According to various embodiments, the processor 120 of the electronic device 101 may recognize a specific image area from a selfie image and thus extract a user's feature point (distinguishing feature). The processor 120 may generate avatar elements for generating an avatar, and may generate mapping elements mapped to a user image based on the feature point. The processor 120 may apply the avatar elements to a pre-stored basic face model to transform the basic face model into a 3D face shape, and may combine the 3D face shape with mapping elements to generate a user avatar having a 3D face shape. The feature point may include at least one of eyes, a nose, ears, a mouth, spots, scars, a beard, a face shape, a hairstyle, and a skin color. The mapping elements may include at least one of shape, shape information, location information, color information, length information, and width information of each feature point.

According to various embodiments, the processor 120 of the electronic device 101 may detect face elements and face outlines from the user avatar. The face element may include eyes, a nose, a mouth, ears, and unique elements (e.g., spots, a beard, glasses, etc.), and the face outlines may include facial lines and a hairline.

The processor 120 may apply the detected face elements and face outlines to a model according to each pose based on a pose set of a defined sticker format and thus change the model to an avatar form corresponding to each pose, and may generate a set of custom stickers into which the changed avatar form is inserted. The pose set having a sticker format may include at least one emotion pose, and may include a model corresponding to each emotion pose. The model may be used to change the shape of face elements and face outlines to a face shape corresponding to the emotion pose. For example, the model can be used to change the user avatar to match the pose of a sticker format corresponding to a facial expression, such as a smiley expression, a crying expression, or an angry expression.

The processor 120 of the electronic device 101 according to various embodiments may detect a condition in which an avatar-related event schedule or an external environment changes, and in response to the detected event schedule or external environment changing condition, may add an image corresponding to the event schedule or external environment changing condition to a custom object and generate an additional custom object. The processor 120 may provide the additional custom object in addition to a set of custom stickers, which have a sticker format and are generated when the application is executed.

The processor 120 of the electronic device 101 according to various embodiments may detect a difference change between a user image recognized by analyzing a gallery database DB and the generated user avatar, and may update a user avatar based on difference change information.

The processor 120 of the electronic device 101 according to various embodiments may identify the other person, who is recognized a defined number of times of frequency or more, in addition to a user, while analyzing the gallery DB, may generate at least one of an avatar and a custom sticker of the other person, and may transmit at least one of the generated avatar and custom sticker of the other person to the other person's electronic device (e.g., the external electronic device 104 of FIG. 1).

FIG. 2 is a block diagram 200 illustrating the camera module 180 according to various embodiments.

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, 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 device 160. Thereafter, if a specified condition is met (e.g., by a user'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 device 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 device 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 this case, for example, at least one of the plurality of camera modules 180 may be a wide-angle camera, and at least another one may be a telephoto camera. Similarly, one of the plurality of camera modules 180 may be a front-facing camera, and at least another one may be a rear-facing camera.

The recognition module 381 and the custom object processing module 385 of the electronic device 301 may be configured to perform the same function as at least some of the functions of the recognition module 331 and the custom object processing module 335 of the external electronic device 308. For example, the recognition module 381 of the electronic device 301 may be hardware configured to recognize a face in an image, and may be used to recognize a face more simply and quickly than the external electronic device 308 (e.g., the server 108) can. The custom object processing module 385 of the electronic device 301 may be used to generate a custom object from the generated avatar.

The external electronic device 308 (e.g., the electronic device 104 or the server 108 of FIG. 1) may include a recognition module 331, a custom object processing module 335, and a storage 337.

According to an embodiment, the processor of the external electronic device 308 may perform both recognition and custom object processing.

In some embodiments, the external electronic device 308 may further include an avatar generation module 333. The avatar generation module 333 of the external electronic device 308 may be configured to perform the same functions as at least some of the functions of the avatar generation module 381 of the electronic device 301. The avatar generation module 333 of the external electronic device 308 may be used to generate a user avatar having higher similarity to a user face than that of a user avatar generated by the electronic device 301.

Images stored in the memory 387 of the electronic device 301 or acquired from the camera module 380, may be uploaded to the storage 337 of the external electronic device 308. The electronic device 301 and the external electronic device 308 may transmit or receive data related to a user avatar through a communication module.

In some embodiments, the electronic device 301 and the external electronic device 308 may operate in cooperation with each other to generate a user avatar and a custom object. Hereinafter, for convenience of explanation, subjects performing respective operations are described as being separately implemented. It is needless to say that the electronic device 301 and the external electronic device 308 may perform respective operations.

According to an embodiment, the recognition module 331 of the external electronic device 308 may recognize at least one image area by applying an object recognition algorithm or a texture recognition algorithm to the image area.

In operation 1720, the processor 120 may determine, from the selected images, whether at least one of feature points and face elements has been changed. The feature points may include at least one of eyes, a nose, ears, a mouth, spots, scars, a beard, face shape, hair, and a skin color.

According to an embodiment, the processor 120 may compare the recognized feature points using a recognition algorithm obtained by applying machine learning or deep learning to determine whether the feature point has changed.

According to an embodiment, the processor 120 may detect changes in the face elements and the face outlines from a user image to determine whether a change in the user's state is detected. The face elements may include eyes, a nose, a mouth, ears, and unique elements (e.g., spots, beard, glasses, etc.), and the face outlines may include facial lines and a hairline.

In operation 1730, the processor 120 may display, on the display screen, guide information about whether to perform avatar update in the case where a change in a feature point or a change in the user's state occurs.

In operation 1740, in the case where the processor 120 receives input agreeing to the avatar update from the user, the processor 120 may update the avatar by changing the avatar based on change information. In operation 1750, the processor 120 may change the configuration using the updated user avatar.

In operation 1760, the processor 120 may change the reprocessed custom object based on the updated user avatar.

FIG. 18 is an exemplary diagram illustrating avatar-based custom object by an electronic device according to various embodiments.

Referring to FIG. 18, according to various embodiments of the disclosure, a processor (e.g., the processor 120 of FIG. 1) of an electronic device (e.g., the electronic device 101 of FIG. 1 or the electronic device 301 of FIG. 3) may, when a difference occurs between a user image recognized by analyzing the gallery database and the generated user avatar, recognize the difference therebetween, and may provide support to apply the difference to the user avatar.

According to an embodiment, the processor 120 may generate a user avatar 1815, which is generated based on a user image 1810 in <1801>, in the form shown in <1802>. The processor 120 may recognize that the state of the user's face elements has been changed to a form of wearing glasses accessory, as shown in <1811>, in the middle of analyzing the gallery database. The processor 120 may recognize the state change of the face elements, recognize the glasses accessory, and generate the user avatar 1815 as a user avatar 1825 wearing glasses in the form shown in <1812>.

According to an embodiment, the processor 120 may be configured to update the user avatar in the case where a defined condition, such as a condition in which the most recent image occurs within a predetermined period of time and a condition in which a state change is repeated the predetermined criterion or more, is satisfied. Accordingly, it is possible to solve the problem of repeatedly implementing user avatar update according to the single occurrence of state change.

FIG. 19 illustrates an avatar-based custom object operation method by an electronic device according to various embodiments.

Referring to FIG. 19, a processor (e.g., the processor 120 of FIG. 1) of an electronic device (e.g., the electronic device 101 of FIG. 1 or the electronic device 301 of FIG. 3) according to various embodiments may identify the other person, who is recognized a defined number of times of frequency or more, in addition to a user, based on the analysis of a gallery database, in operation 1910.

In operation 1920, the processor 120 may output, through the display, guide information notifying of whether to agree to the generation of other person avatar. In operation 1930, in the case of receiving input agreeing to the generation of the other person's avatar, the processor 120 may generate the other person's avatar based on the other person's image recognized in the gallery.

In some embodiments, the processor 120 may generate the other person's avatar-based custom sticker based on the other person's generated avatar.

In operation 1940, the processor 120 may be configured to apply the other person's generated avatar to the other person's profile stored in the electronic device.

In operation 1950, the processor 120 may transmit information of the other person's avatar to the other person's electronic device through a communication module. For example, the processor 120 may output, to a display screen, guide information notifying of whether to transmit information of the other person's avatar to the other person's electronic device, and may transmit the other person's avatar information to the other person's electronic device in response to the user's transmission approval request.

In some embodiments, operation 1950 may be omitted.

In some embodiments, in operation 1950, in the case where the processor 120 generates a custom sticker based on the other person's avatar, the processor 120 may transmit the custom sticker generated based on the other person's avatar to the other person's electronic device.

In operation 1960, the processor 120 may determine whether to update the other person's avatar by determining whether change information for the other person's generated avatar is detected through gallery database analysis. In operation 1970, when the other person's avatar needs to be changed, the processor 120 may provide updated information to other person's electronic device.

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, with or without using one or more other components under the control of the processor. 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'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. According to various embodiments, one or more of the above-described components may be omitted, or one or more other components may be added.
