However, there is no need to clearly illustrate most prior art components.

FIG. 3 is a block diagram illustrating an example of components that a processor of an electronic device according to an embodiment of the present invention can include; FIG. 4 is a diagram illustrating a method that an electronic device according to an embodiment of the present invention can perform; Fig.

The first electronic device 110 according to the present embodiment may be configured with a computer-implemented group communication system. The group call system may be implemented as an application installed on the first electronic device 110 to provide a group call service in a network environment through interworking with the server 150.

For example, the group call system implemented in the first electronic device 110 may perform a method of providing a group call screen based on a command provided by an application installed in the first electronic device 110. 3, the processor 212 of the first electronic device 110 includes an image request unit 310 and a screen configuration unit 320, as shown in FIG. 3, ). The components of processor 212 may optionally be included or excluded from processor 212 in accordance with an embodiment. In addition, in accordance with an embodiment, the components of the processor 212 may be separate or merged for the representation of the functionality of the processor 212.

The processor 212 and the components of the processor 212 may control the first electronic device 110 to perform the steps S410 through S440 included in the group call screen providing method of FIG. For example, the components of processor 212 and processor 212 may be implemented to execute instructions in accordance with the code of the operating system and the code of at least one program that memory 211 contains.

Here, the components of processor 212 may be coupled to processor 212 (e. G., Processor 210) in accordance with instructions provided by the program code stored in the first electronic device 110 (I. E., ≪ / RTI > different functions of processor 212 performed by processor 212). For example, if the image requesting unit 310 is a functional representation of the processor 212 that controls the first electronic device 110 in accordance with the instructions described above, such that the first electronic device 110 requests an image for the group call Can be used.

In step S410, the processor 212 may read the necessary commands from the loaded memory 211 with instructions associated with control of the first electronic device 110. [ In this case, the read command may include instructions for controlling the processor 212 to execute the steps (S420 to S440) to be described later.

In step S420, the screen configuration unit 320 transmits to the server 150 an intention to participate in the group call of the user of the first electronic device 110. At this time, It is possible to construct a group call screen by rendering a participant image of a predetermined maximum number of persons (e.g., 20,000) as individual images, and then rendering the received participant images as one screen. The server 150 may generate an image including a plurality of participant images and provide the image to the first electronic device 110 instead of providing each participant image as an individual image to the first electronic device 110 And the first electronic device 110 configures a plurality of participant images into a group call screen of one screen. At this time, when providing the participant image of the maximum number of persons, the server 150 provides the participant image with a predetermined minimum size and a minimum frame rate (fps) (e.g., 1 fps). When providing a predetermined number or more of participant images at the same fps, the server 150 does not transmit all participant images at the same time, but distributes the participant images into a plurality of groups and transmits them among the groups within a unit time (1 second) The period can be applied differentially.

In step S430, the image requesting unit 310 requests the server 150 for an image of a plurality of participants participating in the group call. In response to the user input on the group call screen, the participant After determining the number of images, the participant image can be requested to the server 150 again. The user can selectively adjust the number of images to be displayed on the group call screen through gestures such as touch or zoom (pinch zoom in / pinch zoom out) on the group call screen displayed on the display of the first electronic device 110 have. For example, when the user executes the zoom-in process, the number of images displayed on the group call screen becomes small and the number of images increases when the zoom-out process is performed. At this time, the image requesting unit 310 may select a participant image to be displayed on the group call screen on the basis of a point corresponding to the user input, for example, a touch point, and request the server 150 for the selected participant image again. Each participant image may include an identifier for identifying the participant or the image, and may request the server 150 again for the image selected by the user using the identifier of the image.

In step S440, the screen configuration unit 320 receives each participant image from the server 150 in response to a request for the participant image, and renders the received participant image in one screen to reconstruct the group call screen can do. At this time, the server 150 may adjust the image size and fps to be provided to the first electronic device 110 again in correspondence with the number of participant images requested by the first electronic device 110 again. In other words, the server 150 may adjust the size and fps of the participant image according to the number of participant images to be displayed on the group call screen. The larger the number of participant images to be displayed on the group call screen, the smaller the image size and fps, and the smaller the number of participant images to be displayed on the group call screen, the larger the image size and fps. If the number of participant images re-requested by the first electronic device 110 is equal to or greater than a predetermined number, the server 150 divides the participant images into a plurality of groups and applies the different transmission periods between the groups within a unit time (1 second) When less than a predetermined number of participant images are requested, the participant images of the same fps can be collectively transmitted at the same time in units of time.

Accordingly, the group call system can provide a group call screen composed of participant images of the smallest size at the initial stage of participating in the group call, and can provide group call screens composed of participant images of a larger size step by step through the enlargement gesture.

5 to 7 are exemplary diagrams illustrating a process of configuring a group call screen by receiving a participant image according to an exemplary embodiment of the present invention.

5, the server 150 receives images in real time between the electronic devices 50-1, 50-2, 50-3, ..., 50-n of participants participating in a specific group call Thereby providing a group call service. When the user of the first electronic device 110 participates in the group call, the participant images 51-1, 51-2, 51-3, ..., 51-m of the predetermined number of persons (M persons) 1 < / RTI > At this time, the first electronic device 110 renders the participant images 51-1, 51-2, 51-3, ..., 51-m received as individual images from the server 150 on one screen, (500).

The server 150 may determine the image size and fps to be provided to the first electronic device 110 according to the number of images requested by the first electronic device 110. [ The number of images to be displayed on the group call screen 500 can be adjusted in a plurality of steps (L), and as shown in FIG. 6, the image size 610 and fps 620 ) Can be predetermined. The image size 610 and the fps 620 decrease as the number of images to be displayed on the group call screen 500 increases and the image size 610 decreases as the number of images to be displayed on the group call screen 500 decreases. And the fps 620 become larger. For example, the group call screen 500 can be composed of four steps of 20,000, two hundred, four, and one images. In the step of providing a maximum size image (L step) Size image (step 1), the image can be updated at 1 fps.

When the number of images to be displayed on the group call screen 500 is large, fps is reduced. When the server 150 transmits a predetermined number or more of participant images to the first electronic device 110, 1 second). 7, the server 150 divides the participant images 51-1, 51-2, 51-3, ..., and 51-m with a predetermined time interval within a unit time (1 second) To the electronic device (110). At this time, the server 150 may divide the image data into a plurality of groups according to the number of images, and transmit the divided images to different groups within a unit time (1 second). In the case of a certain number or more of images, the images are divided at intervals of time, and in the case of images less than a certain number, the entire image can be collectively updated at the same time. As the number of images increases, the fps can be reduced to update the screen slowly, and the screen can be updated with time intervals between images.

8 to 10 are exemplary diagrams illustrating a process of rearranging group call screens in an embodiment of the present invention.

The first electronic device 110 can freely configure the group call screen 500 because the first electronic device 110 receives the participant images 1 to M from the server 150 as individual images. For example, the first electronic device 110 can configure the group call screen 500 by dividing the screen area by the number of participants in the form of a grid or a mosaic, and arranging the participant images 1 to M in the divided areas And it is easy to move or delete the participant images (1 to M) displayed on the group call screen (500).

For example, referring to FIG. 8, the first electronic device 110 may display a position where a user selects and moves a specific image 80 among the participant images 1 to M displayed on the group call screen 500 The group call screen 500 can be rearranged by moving the selected specific image 80 to the corresponding position (for example, when the specific image 80 is touched and dragged to a desired position).

9, when the user selects a position to set and move the area 90 on the group call screen 500 (for example, after designating the area 90, The user can move the images belonging to the area 90 to the corresponding position.

In addition to moving the position of the image displayed on the group call screen 500, it is also possible to select and delete at least one image displayed on the group call screen 500. 10, when the user selects a specific image 100 among participant images 1 to M displayed on the group call screen 500 and inputs a gesture for deletion (FIG. 10), the first electronic device 110 For example, when the specific image 100 is dragged out of the group call screen 500 while the specific image 100 is touched), the selected specific image 100 can be deleted from the group call screen 500 and the remaining images can be rearranged. As described with reference to FIG. 9, it is also possible to set an area on the group call screen 500 and delete the images belonging to the area in a batch.

Accordingly, the first electronic device 110 receives the participant image participating in the group call as an individual image from the server 150 and directly renders it on the first electronic device 110 side to construct the group call screen 500, It is possible to provide a group call screen 500 that can be moved or deleted.

11 to 12 are exemplary diagrams illustrating a process of reconstructing a group call screen in an embodiment of the present invention.

In particular, the first electronic device 110 selectively adjusts the number of images to be displayed through a gesture such as touch or zoom (pinch zoom in / pinch zoom out) on the group call screen 500, 500) can be reconfigured.

The number of images to be displayed on the group call screen 500 can be stepwise adjusted in a plurality of steps (L), for example, it is possible to enlarge the number of images in the order of 20,000, 200, 4, and 1, Can be reduced in order of 4 → 2 → 200 → 20. In addition to being sequentially adjusted in one step, it is also possible to adjust in two or more steps depending on the number and size of gestures input.

11, when the user performs a zoom-in operation at an arbitrary position at which the user wishes to enlarge the image of the group call screen 500, the first electronic device 110 displays the enlarged gesture according to the number of images determined in the next step The enlargement target 11 can be determined based on the position. The first electronic device 110 requests the server 150 again for the participant image determined as the enlargement object 11 and the server 150 transmits the image size of the participant image to the server 150 in accordance with the number of images re- And the fps may be adjusted to reconfigure the group call screen 1100 by using the participant image sent again.

On the contrary, when the user performs zoom-out on the group call screen 1100, the first electronic device 110 transmits a participant image whose image size and fps are adjusted in accordance with the number of images corresponding to the previous step from the server 150 And can be reconfigured to the group call screen 500 of the previous step.

12, the first electronic device 110 requests the server 150 to request the participant image determined to be enlarged in the process of reconfiguring the group call screen 1100 of the next step, and at the same time, When the participant image forming the screen 500, that is, the participant image of the previous size, is used to construct the group call screen 1200 of the next step and all the participant images of the enlarged size are received from the server 150, The group call screen 1100 of the final next step can be configured using the participant image of the participant. In other words, when the first electronic device 110 is enlarged from the group call screen 500 of the previous step to the group call screen 1100 of the next step, the first electronic device 110 performs screen rendering from the previous size image, The user can update the final group call screen 1100 by rendering the screen again.

Accordingly, when the first electronic device 110 requests the server 150 to increase or decrease the number of images to be displayed on the group call screen, the first electronic device 110 requests the first electronic device 110 to re- If the image size and fps are adjusted according to the number of images, the group call screen can be reconstructed using the image whose size and fps are adjusted.
