The present invention relates to an image transmission method, and more particularly, to an image transmission method that enables an image transmission to a client terminal.

Recently, the mobile messaging market is rapidly evolving from the short message service (SMS) to the multimedia message service (MMS) era, and the wireless communication solution industry is also beginning to shift generations to MMS.

MMS is a service that is expected to form a huge market in 2nd and 3rd generation mobile communication environments and is one of the powerful applications that will increase sales of mobile phone equipment companies, telecommunications operators and content companies in the fierce competition of mobile market.

In particular, due to the proliferation of camera phones and aggressive MMS services by mobile and fixed-line carriers, the SMS market, which previously occupied the mainstream of the mobile messaging market, is rapidly shifting to MMS.

Multimedia-based mobile communication terminals such as camera phones and MP3 phones are rapidly spreading, and not only mobile carriers but also major cable operators such as Dacom and Onse Telecom are actively using the wireless network open system to enter the MMS service market.

As a result, mobile solution specialists, which have focused on SMS solutions since 2000, are shifting their focus to the MMS equipment business, and are strengthening R & D in the MMS sector to support various types of services.

Locus Technologies, a mobile solutions company, first provided MMS solution for photo transmission service to SK Telecom in 2001, and recently provided Long Message Service (LMS) for long text and multimedia data transmission to KTF. Doing. In particular, MMS roaming service is being supported to SK Telecom.

Korean Patent Publication No. 2004-047444 discloses an image processing method for such a multimedia message service. The first step of generating a plurality of image files having respective file formats compatible with each type of the mobile communication terminal for the original image to be transmitted to a specific mobile communication terminal, and the image from the image files having the plurality of file formats Image processing for a multimedia message service comprising a second step of selecting only an image file of a file format compatible with a receiving mobile terminal to be received, and a third step of transmitting the selected image file to a predetermined receiving mobile terminal. A method is disclosed.

The conventional technology is to process the image to be transmitted to a specific mobile communication terminal from the network terminal to a specific file format of the file format compatible with each terminal type, the terminal model of the mobile communication terminal to receive the image in advance By grasping, only the image file of the file format corresponding to the terminal model can be selectively transmitted to the mobile communication terminal.

However, the prior art as described above had a hassle of having to prepare various types of image formats in order to service an image to a terminal.

In other words, currently used client terminals have different display capabilities and thus have different acceptable images. Therefore, if the original image is transmitted as it is, there is a problem that cannot be received or displayed as a circle. In more detail, the client terminal needs an image format suitable for the size, resolution (number of pixels) and capacity of the display. Therefore, carriers need to prepare and set different kinds of images in advance to match the types of terminals. For example, there are currently 9 types of domestic S companies (GIF (96 * 48 / B & W / freesize), GIF (120 * 80 / 4gray / freesize), GIF (120 * 96 / color / freesize), SIS (96 * 48 / B & W / 1k), SIS (120 * 80 / 4gray / 3k), SIS (120 * 96 / 256c / 7.5k), SIS (120 * 96 / 256c / 10k), SIS (120 * 96/4096 / 20k) , SIS (176 * 144/4096 / 20k)], and pre-fabricated image format and store it in the database server to selectively supply the format suitable for the type of client terminal accessing the main server. I had a problem.

In view of the increasing variety of terminals, this problem is emerging as a problem that requires further improvement, such as continuous upgrade of the database.

In addition, the related art is limited to still images, and has a problem in that a video cannot be transmitted smoothly. In other words, since a video is relatively large, it is difficult to receive and process a video using a client terminal having insufficient processing capacity. In other words, since video requires a much larger memory capacity than still images, it is difficult to receive data from a client terminal and process the data in real time, and furthermore, it requires a lot of storage to store the video. It was.

Therefore, in the related art, when a video is selected from a client, only the first frame is transmitted, thereby accommodating a problem that the client cannot achieve the purpose.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide an image transmission method that can effectively transmit a suitable image format according to the type of the user terminal.

Another object of the present invention is to provide an image transmission method that can obtain a video-like effect by extracting a specific image in the moving picture to be transmitted to a continuous file.

The object of the present invention is to implement a method for transmitting an image to a client terminal connected to the main server, determining whether a prototype image is selected from the client terminal accessed to the main server, and from the main server to the client terminal device; Transmitting a URL for accessing an image, accessing the URL from a client device and simultaneously transmitting client terminal information to a server, sizing the prototype image into an image format corresponding to the read client terminal information; It can be achieved by the image transmission method comprising the step of transmitting the sized image format to the client terminal.

Another object of the present invention is to implement a method for transmitting an image to a client device connected to the main service, determining whether a video is selected from the client accessed the main server, and the image to the client terminal accessed to the main server Transmitting a URL for accessing the URL, transmitting the client terminal information to the server at the same time as the client device accesses the URL, and selecting and buffering a frame having a large change rate from the initial screen and subsequent frames from the selected video. Combining each of the buffered images into a slide image, sizing the combined image into an image format corresponding to the information of the read client terminal, and transmitting the sized image format to the client device Image exhibition consisting of It can be achieved by the delivery method.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 is a block diagram schematically showing the configuration of a preferred embodiment of the image transmission method according to the present invention. The client terminal 10 is connected to the main server 30 through the Internet 20, the database server 40 including the image is linked to the main server 30.

2 is a flowchart illustrating an image transmission method according to the present invention. Accordingly, the present invention determines whether the circular image is selected from the client terminal 10 accessed to the main server 30 (S1). The client terminal 10 includes a conventional portable telephone, a PDA, a desktop PC, a laptop, and the like.

Subsequently, the main server transmits a URL (Uniform Resource Location) to access the prototype image to the client terminal (S2).

The client device accesses the URL and simultaneously transmits client terminal information to the server (S3). The information sent to the client terminal includes information such as terminal type, operating system, display size, resolution, and color express ability.

The main server receives the prototype image from the database server and sizes the image in an image format corresponding to the read client terminal information (S4). According to the type of the terminal, the image format, pixel, color, and capacity of GIF or SIS are determined. For example, GIF (96 * 48 / B & W / freesize), GIF (120 * 80 / 4gray / freesize), GIF (120 * 96 / color / freesize), SIS (96 * 48 / B & W / 1k), SIS ( 120 * 80 / 4gray / 3k), SIS (120 * 96 / 256c / 7.5k), SIS (120 * 96 / 256c / 10k), SIS (120 * 96/4096 / 20k), SIS (176 * 144/4096 / 20k).

The sized image is transmitted to the client terminal (S5). In the client terminal, the image is pre-sized from the main server to be compatible with the operating system and supported in a form that can be displayed on the display, thereby enabling display without additional processing such as transcoding.

3 shows a flowchart of another embodiment of the image transmission method of the present invention. Here, an embodiment in the case where a moving picture is requested from the client terminal is disclosed. Detailed description overlapping with the preferred embodiment will be omitted. As shown in the present invention, it is determined whether a video is selected from the client accessed the main server (S10). The URL to access the image is transmitted to the client terminal accessed to the main server (S20). The client terminal accesses the URL and simultaneously transmits client terminal information to the server (S30). A frame having a large change rate is selected and buffered from the initial screen and subsequent frames from the selected video (S40). Each of the buffered images is combined into a slide image (S50). The combined image is sized to an image format corresponding to the read information of the client terminal (S60). The sized image format is transmitted to the client terminal (S70).

According to this embodiment, the video selected from the client is composed of one frame of several frames with a high rate of change and transmitted to the client terminal, so that actual video information cannot be used, but an image similar to the video information can be obtained. .

The image transmission method according to the present invention described above is not limited to the above embodiments, it should be understood to include the image transmission method by the limitation and addition within the scope without departing from the scope of the technical idea of the present invention.

For example, when an image is transmitted from a client terminal to a main server and a request for transmission to another client terminal is requested, the image between a plurality of client terminals can be transmitted by allowing the main server to transmit an image connection URL from a third client terminal. It should include enabling transmission.

According to the image transmission method according to the present invention described above, before transmitting a still image selected from a client to the client terminal, various information of the client terminal is collected and processed after sizing the still image so as to correspond thereto. This eliminates the need to create a matching image format for each model in advance, reduces the load on the database server, and enables an effective interface.                     

In addition, in the case of a moving picture, frames having a high rate of change are captured, filed, sized, and transmitted so that information similar to an actual moving picture can be obtained.
