FIG. 3 is a flowchart illustrating an example of a method performed by a computer device according to at least one example embodiment.

Referring to FIG. 3, in operation 5310, when providing a list of effects applicable to a camera video for a video call, the processor 220 may recommend an attire body effect based on at least one of (1) user information that requests the list of effects and (2) a call purpose specified by a user.

Herein, the effect may represent an effect filter that may be synthesized in a camera video as content that is configured as an image object. The body effect may represent an effect that may be applied to a body portion excluding a face in the camera video. For example, the attire body effect may represent a body effect that is configured as an image object representing clothes.

A dress code, such as a style, a formality, a shape, and a color of clothes, may be defined according to a gender, an age, an occupation, a time, a place, a situation, etc., and the attire body effect refers to attribute information related to a corresponding effect and may include information on a dress code to which corresponding attire belongs.

The processor 220 may recommend an attire body effect of a dress code that matches user information, such as a gender, an age, and an occupation, or an attire body effect of a dress code that matches a purpose for which the user desires to participate in the video call. Here, the processor 220 may predict a gender or an age of the user from a video analysis result by extracting information from a user profile registered to a service or by analyzing the camera video. Also, the processor 220 may extract the call purpose of the user from meeting information set to a calendar through interaction with the calendar. Depending on example embodiments, the call purpose may be directly set by the user through a setting environment for video call participation.

The processor 220 may identify a dress code through the user information or the call purpose and may provide an attire body effect that matches the identified dress code as a type of a recommended effect.

In operation 5320, when the user selects a body effect of specific attire, the processor 220 may detect a body portion in the camera video and may apply the corresponding attire body effect. The processor 220 may detect and track a face portion and a body portion of the user as a subject area in the camera video through computer vision technology that includes object detection and object tracking. Here, the processor 220 may extract the body portion excluding a face in the camera video and then may overlay and thereby synthesize the attire body effect on the extracted body portion.

In operation 5330, the processor 220 may transmit the camera video in which the attire body effect is applied to the body portion as a user video. That is, the processor 220 may provide the camera video in which the attire body effect is synthesized in the body portion to a terminal of each counterpart that participates in the video call as the user video for the video call.

Herein, the video call may encompass a video call through which video and audio are exchanged between the user and the counterpart, for example, via an Internet telephone (e.g., Voice over Internet Protocol (VoIP)) technology that convers video and audio to a digital packet and transmits the same through a network using an IP address.

The processor 220 may synthesize an attire body effect in a camera video as an augmented reality (AR) image in a streaming environment that transmits a video captured with a camera of the computer device 200 in real time through an Internet line and may provide the same as a single video. The user video includes the appearance of the user wearing virtual attire, instead of clothes the user is actually wearing.

In operation 5340, the processor 220 may receive a counterpart video for the video call from the terminal of the counterpart and may display a video call screen that includes the user video and the counterpart video. The processor 220 may configure the video call screen by receiving each counterpart video that participates in the video call as an individual video and then rendering the received counterpart video with the user video on a single screen.

A server side that provides a video call service may transmit each participant's video as an individual video instead of creating a single video that includes a plurality of participant videos and providing the created video to a client, and a client side may receive each of the plurality of participant videos as an individual video and may configure the same as a video call screen on a single screen.

FIGS. 4 to 6 illustrate a process of providing an attire body effect during a video call according to at least one example embodiment.

FIG. 4 illustrates a video call setting screen 400.

Referring to FIG. 4, the processor 220 may display a video captured with the camera of the computer device 200, that is, a camera video 410 through the video call setting screen 400.

When the user requests an attire change through a video call setting environment before the user participates in the video call, the processor 220 may display a list of attire body effects 420 on the video call setting screen 400.

Here, the list of attire body effects 420 may include recommendation information on attire. For example, the list of attire body effects 420 may include an attire body effect that matches user information, such as a gender, an age, and an occupation, and an attire body effect that matches the purpose of the user that desires to participate in the video call.

For example, if the user is a female in twenties, attire classified into the category of women in 20ties may be recommended. In the case of a video call for a school class, a school uniform may be recommended as attire. In the case of a video call for interview, suite may be recommended. In the case of a video call for a non-face-to-face home party, attire of a dress code (e.g., pajamas) directly set by the user may be recommended.

Referring to FIG. 5, when the user selects a specific attire body effect from the list of attire body effects 420, the processor 220 may detect a body portion 512 excluding a face portion 511 in the camera video 410, may synthesize the attire body effect selected by the user in the detected body portion 512, and then display the same.

The processor 220 may change attire of the user for the video call through the aforementioned process.

The processor 220 may prepare the camera video 410 in which the attire body effect is synthesized as virtual attire not actual attire as the user video for the video call.

When the user changes the attire through the video call setting screen 400 and then inputs a video call participation button (join) 530, the processor 220 may transmit the camera video 410 in which the attire body effect is synthesized to a terminal of each counterpart that participates in the corresponding video call.

Referring to FIG. 6, when the user participates in a video call, the processor 220 may receive counterpart videos 650, 660, and 670 for the video call from terminals of counterparts and may display a video call screen 600 that includes a user video 610 and the counterpart videos 650, 660, and 670.

Here, the processor 220 may configure the video call screen 600 by receiving the respective counterpart videos 650, 660, and 670 of user B, user C, and user D that participate in the video call as individual videos and by rendering the received counterpart videos 650, 660, and 670 with the user video 610 on a screen.

The user video 610 corresponds to a camera video in which an attire body effect selected by the user is synthesized, instead of a video of actual attire.

In addition to synthesizing the attire body effect in the body portion 512 of the camera video 410, the processor 220 may provide a function of changing only a color of clothes actually worn by the user.

In response to a request from the user for changing a color of clothes, the processor 220 may display an interface for color selection on the video call setting screen 400 and may change a color of a clothing object in the body portion 512 to a color selected by the user.

The processor 220 may transmit the camera video in which the color of clothes is changed to a terminal of each counterpart that participates in the corresponding video call as the user video for the video call.

In addition to changing the color of the entire clothing object, when a plurality of clothing objects (e.g., a shirt, a cardigan, etc.) is detected in the body portion 512, the processor 220 may also selectively change a color of a clothing object.

When the user requests a change in a color of clothes, the processor 220 may display an interface for object selection and an interface for color selection on the video call setting screen 400 and, through this, may change a color of a clothing object selected by the user with a color selected by the user.

A camera video of attire of which color is changed with a color selected by the user, instead of a color of actual attire, may be provided as the user video 610 that participates in the video call.

FIG. 7 is a flowchart illustrating another example of a method performed by a computer device according to at least one example embodiment.

The processor 220 may provide a body effect that allows video call participants to wear group uniforms suitable for a call purpose.

Referring to FIG. 7, in operation 5710, when providing a list of effects applicable to a camera video for a video call, the processor 220 may recommend an attire body effect based on a call purpose specified by a user.

The processor 220 may identify the call purpose of the user from meeting information set to a calendar through interaction with the calendar, or may recognize the call purpose directly set by the user through a setting environment for participating in the video call.

According to the call purpose, for example, the processor 220 may recommend a school uniform as attire for a video call for a school class and may recommend attire of a dress code (e.g., pajamas) directly set by the user for a video call for a non-face-to-face home party.

The processor 220 may identify the dress code through the call purpose of the user and may provide an attire body effect suitable for the identified dress code as a type of a recommended effect.

In operation 5720, when the user selects a body effect of specific attire as a group uniform for the video call from the recommended attire, the processor 220 may transmit body effect information on the selected attire to a terminal of each counterpart that participates in the video call for applying a group uniform.

In operation 5730, the processor 220 may detect a body portion in the camera video, may apply a group uniform body effect, and then transmit the camera video in which the group uniform body effect is applied to the body portion as a user video. That is, the processor 220 may transmit the camera video in which the group uniform body effect selected by the user is synthesized in the body portion to the terminal of each counterpart that participates in the video call as the user video for the video call.

The processor 220 may receive information on the terminal of each counterpart or the group uniform body effect, may synthesize the corresponding group uniform body effect in the body portion of the camera video, and may provide the same as a call video.

In operation 5740, the processor 220 may receive the counterpart video to which the group uniform body effect is applied from the terminal of the counterpart and may display a video call screen that includes the user video and the counterpart video. The processor 220 may configure the video call screen by receiving each counterpart video that participates in the video call as an individual video and by rendering the received counterpart video with the user video on a single screen.

Referring to FIG. 8, the processor 220 may receive counterpart videos 850, 860, and 870 for a video call from terminals of counterparts and may display a video call screen 800 that includes a user video 810 and the counterpart videos 850, 860, and 870.

The user video 810 and the counterpart videos 850, 860, and 870 correspond to a camera video in which a group uniform body effect selected by the user is synthesized, instead of a video of actual attire.

In the case of a group uniform, whether to apply the group uniform may be determined according to a counterpart's intent to accept. At least a portion of the counterpart videos 850, 860, and 870 may be provided as a video of actual attire or a video in which an attire body effect directly selected by a corresponding user is applied according to a refusal to apply the group uniform.

FIG. 9 is a flowchart illustrating still another example of a method performed by a computer device according to at least one example embodiment.

Referring to FIG. 9, in operation 5910, when providing a list of effects applicable to a camera video for a video call, the processor 220 may provide a body-off effect as one of body effects.

The body-off effect may correspond to a face-only mode in which only a face portion is displayed and a remaining portion including a body portion and a background portion is not displayed. That is, the body-off effect may display only a face and may hide the remaining portion excluding the face by applying a transparent effect.

In operation 5920, when the user selects the body-off effect, the processor 220 may detect the face portion in the camera video and may apply the body-off effect to the remaining portion excluding the face portion. The processor 220 may detect and track the face portion and the body portion of the user as respective subject areas in the camera video through computer vision technology that includes object detection and object tracking. Here, the processor 220 may extract the face portion in the camera video and may synthesize the body-off effect in the remaining portion that includes the body portion and the background portion.

In operation 5930, the processor 220 may transmit the camera video in which the body-off effect is applied to the remaining portion excluding the face as a user video. That is, the processor 220 may transmit the camera video in which the body-off effect is synthesized in the remaining portion excluding the face to the terminal of each counterpart that participates in the video call as the user video for the video call.

In operation 5940, the processor 220 may receive a counterpart video for the video call from the terminal of the counterpart and may display the video call screen that includes the user video and the counterpart video. The processor 220 may configure the video call screen by receiving a counterpart video of each counterpart that participates in the video call as an individual video and rendering the received counterpart video with the user video on a single screen.

FIGS. 10 and 11 illustrate a process of providing a body-off effect during a video call according to at least one example embodiment.

FIG. 10 illustrates a video setting screen 1000 for a video call.

Referring to FIG. 10, the processor 220 may display a video captured with the camera of the computer device 200, that is, the camera video 1010 through the video setting screen 1000.

When the user requests an effect setting through a video setting environment before participating in the video call, the processor 220 may display a list of body effects 1020 on the video setting screen 1000.

Here, the list of body effects 1020 may include an attire body effect capable of changing attire of a user and a body-off effect (off) 1021 that is a face-only mode for displaying only a face and hiding a body and a background.

When the user selects the body-off effect 1021 from the list of body effects 1020 through the video setting screen 1000, the processor 220 may provide a camera video in which a remaining portion excluding a face is hidden through a transparent effect as a user video for the video call.

Referring to FIG. 11, the processor 220 may receive counterpart videos 1150, 1160, and 1170 for a video call from terminals of counterparts and may display a video call screen 1100 that includes a user video 1110 and the counterpart videos 1150, 1160, and 1170.

Here, the processor 220 may configure the video call screen 1100 by receiving the respective counterpart videos 1150, 1160, and 1170 of user B, user C, and user D that participate in the video call as individual videos and rendering the received counterpart videos 1150, 1160, and 1170 with the user video 1110 on a single screen.

The user video 1110 corresponds to a camera video in which a body-off effect of displaying only a face without displaying actual attire or a background is synthesized.

According to the example embodiments, it is possible to provide a body effect of attire suitable for user information or a call purpose during a video call and/or to provide a body effect of a group uniform applicable to a plurality of participants participating in the video call. Also, according to the example embodiments, it is possible to provide a body effect that may display only a face and hide the rest during a video call.

According to the example embodiments, a list of attire body effects is created based on at least one of (1) user information extracted from a registered user profile or an analysis result of a camera video/image of a user and (2) a call purpose is extracted from meeting information on a calendar of the user. Then, a user interface at which the list of attire body effect is provided and the user is allowed to select a specific attire body effect (including, but not limited to, a group uniform applicable to a plurality of participants participating in the video call and a fac-only (or body-off) effect) from a list of attire body effects is provided on a call screen of the user. Thus, the user can apply an attire body effect to a body portion of the user (or a plurality of users) in the camera video/image using the intuitive user interface and create an augmented reality (AR) image, without performing a series of operations with further computing resources.
