The present invention relates to a method of retrieving image information using the Internet, and more particularly, by adding a quick search icon to a user's information search browser to reduce the corresponding image information to a predetermined size when the user selects the fast search icon. The present invention relates to a fast search method of image information that enables a user to shorten an image information search time.

In general, when receiving information service from a communication server using the Internet or personal computer (PC) communication to search, search, and scan specific information, text information is provided in an option provided to a user in an information search browser. There is a text search that searches only the bay, and a full document search that searches the entire document including text information and image information. However, when a modem is attached to a general telephone line and an information service is provided from a communication server using the Internet or PC communication, the communication speed is usually only tens of Kbps information. Accordingly, when the user selects the entire document search, the information content to be searched includes not only text but also image information, which increases the time required to receive the information due to the large amount of information. there was.

A conventional method for retrieving image information with reference to FIG. 1 is as follows.

1 is a block diagram schematically showing the configuration of a computer communication system for retrieving conventional image information, which is connected to a communication server 20 that services various information, and a communication server 20 through a communication network 11. The information search screen 10 on the service subscriber computer. Here, the communication server 20 is referred to as a text information database (hereinafter referred to as DB) 15, a central processing unit 13 and a central processing unit 13 connected to the image information DB 16 and the main memory 14. The communication interface 12 connected to () is provided.

In FIG. 1, the service subscriber accesses an information service such as the Internet or PC communication, and then selects an icon (not shown) corresponding to a text search on the search screen 10 so that the communication network 11 can access the central processing unit 13. Requests transmission of the text information from the text information DB 15. The communication server 20 receiving the request for the transmission of the text information from the service subscriber receives the text information from the text information DB 15 at the central processing unit 13 and transmits the text information to the service subscriber through the communication interface 12 and the communication network 11. do.

On the other hand, when the service subscriber selects an icon (not shown) corresponding to the entire document search on the information search screen 10, the communication server 20 performs the text information from the text information DB 15 at the central processing unit 13. And image information from the image information DB 16 are combined into one file and transmitted to the service subscriber via the communication interface 12 and the communication network 11. Here, the text information DB 15 and the image information DB 16 may be stored as one DB as information.

However, as described above, when the service subscriber searches the entire document, the information content includes a graphic or an image, and thus a large amount of information takes a long time to transmit the information from the communication server to the service subscriber. In this case, a text search may be selected to speed up the search, but if an image capable of determining a shape such as product information is required, the entire document search must be selected. Therefore, it takes a long time to receive the image information, and as a result, the information retrieval speed is significantly reduced. In addition, when the received information is not desired, another information must be searched again. Therefore, the conventional image information retrieval method, which is slow in overall information retrieval, is very inconvenient for the service subscriber.

The present invention has been made to improve the above disadvantages, and an object of the present invention is to add a fast search button to the information search browser to reduce the corresponding image information by a certain ratio when the service subscriber selects the fast search button; By providing a fast image transmission by the transmission to provide a fast search method of the image information to reduce the time for the service subscriber to retrieve the image information.

In order to achieve the above object, the high-speed retrieval method of image information according to the present invention is a method of retrieving information using a communication network, in the case where there is information to be transmitted from the communication server to the service subscriber, the content of the information to be transmitted is composed only of text. A first step of transmitting the text information to the service pressurizer; and if the content of the information includes an image in addition to the text, when the service subscriber selects the document search button, the corresponding text information and the image information in the communication server. And a third step of transmitting the text information and the reduced image information into a single file in the communication server when the server subscriber selects the fast search button. Characterized in that it comprises a step. In this case, the reduced image information may be information stored in a separate image DB, or image information reduced at a predetermined rate when the service subscriber requests a fast search by providing an image reduction means.

Other objects and advantages of the present invention other than the above objects will become apparent from the description of the embodiments of the present invention with reference to the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS. 2 to 6.

2 is a block diagram showing the configuration of a computer communication system for a method for fast image information search according to a first embodiment of the present invention. Comparing FIG. 2 with FIG. 1 showing the conventional system, the communication system of FIG. 2 has a separate image information DB 17 storing reduced image information in the communication server 20 and an information search screen of a service subscriber. 10) is further provided with a fast search button.

4 is a flowchart illustrating a fast searching method of image information according to the first embodiment of the present invention, which is a process performed by the communication server 20 of FIG. Hereinafter, a fast searching method of image information according to a first embodiment of the present invention will be described with reference to FIGS. 3 and 4.

First, the service subscriber starts by accessing information services such as the Internet or PC communication. In a tenth step, the communication server 20 determines whether there is information to be transmitted to the service subscriber. If there is information to be transmitted by the service subscriber requesting the information transmission, the communication server 20 determines whether the content of the information to be transmitted is composed of text only in the eleventh step. If the information content is composed of text only in step 11, the process proceeds to step 15, the central processing unit 13 of the communication server 20 obtains the corresponding text information from the text information DB (15) and transmits it to the service subscriber.

On the other hand, if the information in the information to be transmitted from the communication server 20 includes image information in addition to the text in step 11, the communication server 20 determines whether the service subscriber selected the entire document search button in step 12 do. If the service subscriber selects the entire document search in step 12, the process proceeds to step 15, and the central processing unit 13 of the communication server 20 receives the corresponding text information and image from the text information DB 15 and the image information DB 16. The information is combined and sent to the service subscriber.

When the service subscriber does not select the entire document search button in step 12, the communication server 20 determines whether the service subscriber selects the fast search button in step 13. When the service subscriber selects the fast search in step 13, the central processing unit 13 of the communication server 20 obtains corresponding information from the text information DB 15 and the reduced image information DB 17 in step 14, respectively. It is composed of one new file and transmitted to the service subscriber (step 15).

FIG. 3 is a block diagram illustrating a computer communication system for a method of searching for high-speed image information according to a second embodiment of the present invention. Compared with the conventional system of FIG. 1, the communication system of FIG. An image reduction means 18, i.e., a real-time converter, connected to the image information DB 16 and the central processing unit 13, and a fast search button are further provided on the information search screen 10.

Beginning by the service subscriber accessing the information service, it is determined whether there is information to be transmitted from the communication server 20 (step 20). Here, if there is information to be transmitted in the information transmission request of the service subscriber, the communication server 20 determines whether the information content is composed only of text, and if the information is composed only of text, the central processing unit 13 of the communication server is the text information DB. The corresponding information is taken from (15) and transmitted to the service subscriber (steps 21 and 26).

On the other hand, when the content of the information to be transmitted in step 21 includes image information in addition to text, when the service subscriber selects the document search button, the communication server 20 transmits the text information DB from the central processing unit 13. The corresponding text information and image information are taken from the 15 and the image information DB 16, and are composed into one file and transmitted to the service subscriber (steps 22 and 26).

Then, when the service subscriber selects the fast search button, the communication server 20 reduces the corresponding image information from the image information DB 16 by a predetermined ratio through the real-time converter 18, and the central processing unit 13 The text information from the text information DB 15 and the reduced image from the real-time converter 18 are composed into one new file and transmitted to the service subscriber (steps 23 to 26).

At this time, the image information in the communication server 20 may be reduced to a certain ratio as shown in FIG. In FIG. 6, (a) shows a combination of the text 4 and the original image 5, (b) shows a combination of the text and the image reduced in half, and (c) the text and 1 Displays the screen combined with / 4. Accordingly, when the service subscriber selects the fast search, the communication server reduces and transmits the corresponding image information as shown in FIG. 6, thereby shortening the information search time.
