Abstract

Disclosed-herein is an image-based search system and method. The image-based search system includes at least one user terminal, an information communication network, a search server, and a web server. The user terminal transmits any one or more of a search term entry signal, an image selection signal and an image combination signal to a search server and receives relevant search results from the search server. The information communication network connects the user terminal, the search server and a web server to one another. The search server receives any one or more of the search term entry signal, the image selection signal and the image combination signal from the user terminal, performs searching using attribute information of an image, and transmits search results, including images, to the user terminal. The web server forms a physical space over the information communication network, in which websites, which are objects from which information is gathered by the search server, exist.

Claims

1. An image-based search system, comprising:

at least one user terminal for transmitting any one or more of a search term entry signal, an image selection signal and an image combination signal to a search server and receiving relevant search results from the search server;

an information communication network for connecting the user terminal, the search server and a web server to one another;

the search server for receiving any one or more of the search term entry signal, the image selection signal and the image combination signal from the user terminal, performing searching using attribute information of an image, and transmitting search results, including images, to the user terminal; and

the web server for forming a physical space over the information communication network, in which websites, which are objects from which information is gathered by the search server, exist.

2. The image-based search system as set forth in claim 1, wherein the user terminal is any one of a personal computer, a Personal Digital Assistant (PDA) and a mobile phone.

3. The image-based search system as set forth in claim 1, wherein the user terminal includes a function of displaying attribute information of a selected or combined image and a function of modifying or adding attribute information.

4. The image-based search system as set forth in claim 1, wherein the search server includes a function of performing searching based on image simulation when the search server or the web server receives an image simulation signal, requesting searching using attribute information of an image, which is obtained through the image simulation, the image being directly created, assembled or processed by a user through the image simulation, the image simulation being provided to the user terminal through the search server or the web server.

5. The image-based search system as set forth in claim 4, wherein the search server includes a function of displaying a multi-recommendation signal to the user terminal with respect to one or more of clothes images based on the image simulation when the image simulation is related to a clothes image.

6. The image-based search system as set forth in claim 4, wherein the search server or the web server includes a function of encoding attribute information, including processed information, in the image, obtained from the image simulation, using an encoding function included in the image simulation itself.

7. The image-based search system as set forth in claim 4, wherein the search server or the web server includes a function of recording the attribute information of the image into the image obtained from the image simulation, and, when the image is used in image simulation again, displaying processed information in the image simulation on the user terminal again based on the recorded attribute information.

8. The image-based search system as set forth in claim 1, wherein the search server includes a function of, when a found image is an image of a product, providing price comparison information of the product in search results.

9. The image-based search system as set forth in claim 1, wherein the search server includes a function of transmitting a received search term to an additional search engine, receiving search results, including images found by the search engine, and providing the search results to the user terminal.

10. The image-based search system as set forth in claim 1, wherein the web server includes a function of receiving an image, registered by an image registrant, in order to provide the image to the search server, and encoding and stored attribute information of the image in the registered image.

11. The image-based search system as set forth in claim 1, wherein the search server comprises:

an image gathering unit for accessing a number of websites, providing images, at regular intervals and gathering images from the web server;

a search DataBase (DB) for storing search information, including the images gathered by the image gathering unit; and

an information search unit for searching the search DB for search information, including the images, and displaying the search results on the user terminal.

12. The image-based search system as set forth in claim 11, wherein the image gathering unit comprises:

an attribute information reception unit for receiving attribute information of the gathered images;

an encoding unit for encoding the received attribute information of the images in image files; and

a decoding unit for decoding the encoded attribute information.

13. The image-based search system as set forth in claim 12, wherein, when a received image is an image of a product registered with an on-line shopping mall, the attribute information encoded by the encoding unit includes any one or more of a product name and a keyword of the product.

14. The image-based search system as set forth in claim 12, wherein, when a received image is a still image of a moving image, the attribute information encoded by the encoding unit includes any one or more of a moving image title and a keyword of the moving image.

15. The image-based search system as set forth in claim 12, wherein the attribute information encoded by the encoding unit includes link information of a website from which an image is received.

16. The image-based search system as set forth in claim 12, wherein, when the encoded image is an image obtained through image simulation, the encoding unit includes a function of encoding attribute information including processed information.

17. The image-based search system as set forth in claim 16, wherein the encoding unit includes a function of assigning a unique identification (ID) to each piece of processed information.

18. The image-based search system as set forth in claim 12, wherein the encoding unit includes a function of inserting an encoding signal into an image file so that whether to perform encoding can be determined.

19. The image-based search system as set forth in claim 11, wherein the information search unit comprises a dictionary creation unit for creating a dictionary for indexing.

20. The image-based search system as set forth in claim 11, wherein the information search unit includes a function of providing pattern information specified based on determination of subject area information or background area information of an image.

21. The image-based search system as set forth in claim 20, wherein the information search unit further includes a function of providing color information of an image.

22. An image-based search method, comprising:

(a) gathering search object images;

(b) determining whether the gathered search object images include attribute information;

(c) if, as a result of the determination at the (b), the gathered search object images include the attribute information, performing image decoding;

(d) storing the search object images and the attribute information; and

(e) receiving a search request signal, performing searching in conformity with the search request signal, and then outputting search results.

23. The image-based search method as set forth in claim 22, wherein the (d) comprises (d-1) indexing the attribute information in order to facilitate searching.
