Abstract

A method for selecting an area of content for enlargement is provided. Content including a plurality of objects is displayed. A user'"'"'s selection of an area is received and the selected area is identified. At least one object that crosses into the selected area is selected. An importance value of the at least one selected object is calculated considering a crossing range of the selected area and the at least one selected object. At least one to-be-displayed object is extracted based on the importance value. The at least one extracted object is displayed.

Claims

1. A method for selecting an area of content for enlargement, the method comprising the steps of

displaying the content comprising a plurality of objects;

receiving a user'"'"'s selection of an area of the content, and identifying the selected area;

selecting at least one object that crosses into the selected area;

calculating an importance value of the at least one selected object in accordance with a crossing range of the selected area and the at least one selected object;

extracting at least one to-be-displayed object based on the calculated importance value; and

displaying the at least one extracted object.

2. The method as claimed in claim 1, wherein the importance value is obtained by calculating a ratio of an object area with respect to a crossing area.

3. The method as claimed in claim 1, wherein the at least one object has a predetermined weight and the importance value is obtained by multiplying a ratio of an object area with respect to a crossing area by the predetermined weight.

4. The method as claimed in claim 1, wherein extracting the at least one to-be-displayed object comprises:

calculating a reference value for the importance value; and

extracting the at least one to-be-displayed object having an importance value that is greater than or equal to the reference value.

5. The method as claimed in claim 4, wherein the reference value is a median value of the importance value of the at least one selected object.

6. The method as claimed in claim 1, wherein displaying the at least one extracted object comprises combining the at least one extracted object and re-constructing to-be-displayed content.

7. The method as claimed in claim 1, wherein displaying the at least one extracted object comprises adjusting a size of the at least one extracted object to a size of a display, in accordance with a size and a resolution of the display, so as to display the at least one extracted object.

8. An apparatus for providing content, comprising:

a display for displaying at least one of the content and an object, in accordance with a size and resolution of a screen;

memory for storing content comprising a plurality of objects;

a user input unit for identifying a partial area of the display selected by a user; and

a controller for selecting at least one object that crosses into the selected area on the display, calculating an importance value of the at least one selected object in accordance with a crossing range of the selected area and the at least one selected object, extracting at least one to-be-displayed object based on the calculated importance value, and controlling an operation of the display.

9. The apparatus as claimed in claim 8, wherein the memory stores browser program data for displaying the content, and the controller controls the display of the content via a calculation of the browser program data.

10. The apparatus as claimed in claim 8, wherein the controller calculates a ratio of an object area with respect to an object crossing area as the importance value.

11. The apparatus as claimed in claim 8, wherein the memory stores a predetermined weight for the at least one object and the controller multiplies a ratio of an object area with respect to an object crossing area by the predetermined weight to calculate the importance value.

12. The apparatus as claimed in claim 8, wherein the controller calculates a reference value for the importance value and extracts the at least one object having an importance value that is greater than or equal to the reference value as the at least one to-be-displayed object.

13. The apparatus as claimed in claim 12, wherein the controller calculates an average of the importance value of the at least one selected object as the reference value.

14. The apparatus as claimed in claim 8, wherein the controller combines the at least one extracted object to re-construct to-be-displayed content.

15. The apparatus as claimed in claim 8, wherein the display unit adjusts a size of the at least one extracted object to a size of a display screen to display the at least one extracted object.

16. A system for providing content, comprising:

a content management server for managing content including a plurality of objects; and

a portable terminal for receiving content through communication with the content management server,

wherein the content management server stores and manages the content, provides the content according to a request of the portable terminal, receives a selected area from the portable terminal, selects at least one object that crosses the selected area, calculates an importance value of the at least one selected object in accordance with a crossing range of the selected area and the at least one selected object, extracts at least one to-be-displayed object based on the importance value, and transmits the at least one extracted object to the portable terminal, and

the portable terminal adjusts the content received from the content management server to a resolution for display of the content, receives a selection of an area from the user, identifies the selected area for transmission of data of the selected area to the content management server, and adjusts the at least one object received from the content management server to a resolution for display of the at least one adjusted object.
