Can be.

Hereinafter, the image data control server 300 and the drag and drop-based image data control system will be described in detail with reference to the components of the controller 320.

The image selection transmission module 321 controls the transceiver 310 to receive an access request through the network 200 after loading the image onto the drag and drop browser 120 by the transmission smart device 100. do.

The image selection transmission module 321 may select the image loaded using the drag and drop browser 120 output on the input / output unit 110 of the transmission smart device 100 and then on the drag and drop browser 120. When recognizing the drag control signal with respect to the preset direction, the transceiver 310 may be controlled to receive the selected coordinate (selected coordinate information) and the dragged coordinate information (drag coordinate information) through the network 200.

Meanwhile, in the present invention, the input / output unit 110 will be described based on a touch screen for convenience of description below, but may be configured as a mouse, a keyboard, etc. as an input unit, and may separately configure a display device such as an LCD or an LED as an output unit. .

In one embodiment of the present invention, the transmission position setting module 322 analyzes the dragged direction using the drag coordinate information from the selected coordinate information, and then determines the position of the drop event occurrence coordinate in the final drag coordinate information in the network 200. After receiving from the transmission smart device 100 through, it may be analyzed whether or not the drop zone (drop zone) 130 of the drop event occurrence coordinate position. The drop zone 130 may be programmed and set on the outer circumference or outer circumferential surface of the image when the drag and drop browser 120 is loaded.

The transmission location setting module 322 designates an image transmission target for images selected by all of the receiving smart devices 400-1 to 400-m when analyzing the drop event occurrence coordinate position into the drop zone 130. After that, the transmission capacity setting module 323 notifies the terminal identification numbers and the selected images of all the designated receiving smart devices.

In another embodiment of the present invention, the transmission position setting module 322 is a drop zone 130 of a drop event occurrence coordinate position, and the first to nth receiving user slots S1 to N on the drop zone 130. It is possible to analyze whether or not Sn (n is one or more natural numbers equal to or different from m).

Accordingly, the transmission location setting module 322 is a drop zone 130 of a drop event occurrence coordinate position and receives a smart device corresponding to a user slot including a drop event occurrence coordinate when analyzing one drop into a user slot. After designating as an image transmission target for the selected image, the selected image is notified to the user-selected capacity collection module 324.

Meanwhile, when the drop event occurrence coordinate position does not correspond to the drop zone, the transmission position setting module 322 transmits a redo notification to the image selection transmission module 321 so that a preset time elapses from the point where the drag and drop occurs. The coordinate analysis of the image selection and the drag and drop event can be performed again later.

The transmission capacity setting module 323 starts to be driven according to the entire transmission request of the transmission location setting module 322, and drags and drops the browser before and after loading the image onto the drag and drop browser 120 by the transmission smart device 100. The transmission position setting module 322 transmits the image selected by the transmission smart device 100 to the image quality or data capacity proportional to the received window size setting information by requesting the window size setting information to the transmission smart device 100. The transmitter / receiver 310 may be controlled to transmit the selected image to all the receiving smart devices 400-1 to 400-m by using the terminal identification numbers of all the receiving smart devices.

More specifically, the transmission capacity setting module 323 transmits a high-quality clear image by increasing the transmission data and the screen resolution (Resolution) in proportion to the size of the window selected for image transmission from multiple screen windows on a smartphone or a PC screen. Small screens transmit data by reducing the transmission data and screen resolution.

In addition, when the administrator who operates the transmission smart device 100 wants to show a user of a small screen to a person who is more clearly connected, the transmission capacity setting module 323 drags the small screen while pressing with a hand or a mouse. When placed on a large screen, it can be automatically changed to high resolution.

At this time, the transmission capacity setting module 323, which is a program for internal resolution control and data transmission, is automatically executed to transmit high resolution and high capacity data when selecting a large screen, and to transmit low resolution and low capacity data in a small screen. .

The automatic capacity setting module 323a receives terminal identification numbers and selected images of all receiving smart devices received from the transmission location setting module 322 and onto the drag and drop browser 120 by the song smart device 100. If the size of the drag and drop browser 120 window setting information is requested to the transmitting smart device 100 before and after image loading, and the received window size setting information cannot be specified, the preset steps (steps 1 to L and L) May control the transceiver 310 to transmit the selected image with a data capacity corresponding to one of the capacity of each of the two or more natural numbers). Here, when the window size setting information cannot be specified according to the request for the transmitting smart device 100, the input for the minimize button of the window implementing the drag and drop browser 120 by the transmitting smart device 100 is input. Accordingly, the drag and drop browser 120 can be specified to have the maximum pixel size on the input / output unit 110 according to the case where the window cannot be recognized on the current input / output unit 110 or the input of the maximize button. It may be the case.

The user-selected capacity collecting module 324 is driven in response to a partial transmission request of the transmission location setting module 322, and the drop zone 130 is selected among the receiving smart devices 400-1 to 400-m stored in the database 330. ), The transceiver 310 may be controlled to transmit the selected image to the selected receiving user smart device as one of the first to nth receiving user slots S1 to Sn. In this case, the user-selected capacity collecting module 324 stores a capacity selection designated by the receiving user smart device selected as one of the first to nth receiving user slots S1 to Sn on the drop zone 130 for the capacity of the selected image. In operation 330, the transceiver 310 may be controlled to switch and transmit the selected image with the extracted capacity option.

5 is a flowchart illustrating a drag and drop based image data control method according to an exemplary embodiment of the present invention. Referring to FIG. 4, the image selection transmission module 321 receives an access request through the network 200 after loading an image onto the drag and drop browser 120 by the transmission smart device 100 ( S11).

After the step S11, the image selection transmission module 321 transmits a drag control signal in one of preset directions on the drag and drop browser 120 after the selection of the image loaded on the transmission smart device 100. Received through and recognized (S12). Here, the preset directions are 4 directions (up, down, left, right), 8 directions (up, down, left, right, top, left, top, bottom, left and right), and other 4xk directions (k is a natural number of 3 or more). Can be.

After step S12, the transmission position setting module 322 analyzes the network 200 to analyze the position recognized as a drop event that ends the drag according to the dragged direction matching one of the preset directions. Receives the selected coordinates (selected coordinate information) and the dragged coordinate information (drag coordinate information) performed on the transmission smart device 100 through (S13).

After step S13, the transmission position setting module 322 determines the drop event occurrence coordinates in the final drag coordinate information to determine whether the analyzed position is designated as a user of all the receiving smart devices 400-1 to 400-m. After receiving the position from the transmitting smart device 100 via the network 200, the first to nth receiving user slots S1 to Sn of the drop event occurrence coordinate position (n is one or more natural numbers equal to or different from m). It does not belong to one of the areas, but it is analyzed whether or not the drop zone (drop zone) (130) (S14).

When it is determined in step S14 that all of the receiving smart device users are designated, the transmission position setting module 322 transmits both of the first receiving smart device 400-1 to the nth receiving smart device 400-n to be transmitted. After the designation, the transmission capacity setting module 323 is driven (S15).

After the step (S15), the transmission capacity setting module 323 transmits the selected image in the image quality or data capacity proportional to the size of the window before transmission or corresponds to one step of the step capacity preset by the automatic capacity setting module 323a. The selected video is transmitted at the data capacity of the device (S16).

That is, the transmission capacity setting module 323 transmits the size setting information of the drag and drop browser 120 window to the transmission smart device 100 before and after loading the image onto the drag and drop browser 120 by the transmission smart device 100. All received by using the terminal identification number of all the receiving smart device received from the transmission position setting module 322 the image selected by the transmitting smart device 100 in the image quality or data capacity proportional to the window size setting information received by request The transceiver 310 may be controlled to transmit the selected image to the smart devices 400-1 to 400-m.

In addition, the transmission capacity setting module 323 may implement a drag and drop browser 120 by the transmission smart device 100 when the window size setting information cannot be specified according to a request for the transmission smart device 100. The drag and drop browser 120 window may not be recognized on the current input / output unit 110 according to the input of the minimize button of the window, or may be specified to have a maximum pixel size on the input / output unit 110 according to the input of the maximize button. When one or more transmission capacities are exceeded, the transceiver 310 may be controlled to transmit the selected image at a data capacity corresponding to one of the capacities according to preset steps (first to Lth and L is a natural number of two or more). .

On the other hand, if it is not designated as all the receiving smart device users in step S14, the transmission position setting module 322 determines whether or not the analyzed position is designated as a predetermined receiving smart device user (S17). That is, the transmission position setting module 322 is a drop zone 130 of a drop event occurrence coordinate position, and the first to nth receiving user slots S1 to Sn (n is m on the drop zone 130). A receiving smart device user matching each receiving user slot may be extracted by analyzing whether the information belongs to one or more natural numbers equal to or different from each other).

As a result of the determination in step S17, if the analyzed position is not designated as a preset receiving smart device user, the transmission position setting module 322 notifies the image selection transmission module 321 to perform the retransmission to step S12. Send it.

Meanwhile, as a result of the determination in step S17, when the analyzed location is designated as the preset smart user, the transmission location setting module 322 selects the received smart device set as the analyzed location as an image transmission target and then selects a user. The capacity collection module 324 is driven (S18).

After the step S18, the user-selected dose collection module 324 extracts the preset dose option of the selected receiving smart device from the database 330 and transmits the selected image as the extracted dose option through the network 200. (S19).
