Abstract

Provided are an adaptive document display apparatus and method, and more particularly, an adaptive document displaying apparatus and method which can adaptively convert a document according to the screen size of a device that is to display the document. The adaptive document displaying apparatus includes: a document analyzing unit analyzing each of a plurality of components included in a document; and a document converting unit converting the document according to the result of analysis and attributes of a display device.

Claims

1. An adaptive document displaying apparatus comprising:

a document analyzing unit analyzing each of a plurality of components included in a document; and

a document converting unit converting the document according to the result of analysis and attributes of a display device.

2. The apparatus of claim 1, wherein the document analyzing unit comprises:

a document tree creating unit creating a document tree which represents the hierarchical relationships between the components and comprises a plurality of nodes corresponding to the components, respectively; and

a summary information creating unit creating summary information of each component.

3. The apparatus of claim 2, wherein the document tree creating unit assigns attributes of each component to a corresponding node, wherein the attributes of each component comprise at least one of layout, presentation style and content format of the component.

4. The apparatus of claim 3, wherein the document tree creating unit calculates a priority of each component based on the attributes of the component, a user'"'"'s profile and the attributes of the display device.

5. The apparatus of any one of claims 2 through 4, wherein the summary information creating unit adds various lengths of summary information to each node of the created document tree in order to adjust the amount of contents which are to be displayed in a display region of a component corresponding to the node.

6. The apparatus of claim 1, wherein the document converting unit comprises:

a document style converting unit converting presentation style of each component according to the attributes of the display device; and

a layout converting unit converting a size of a display region of each component and converting the amount of contents, which are to be displayed in the display region of the component, according to the size of the display region of the component,

wherein the presentation style of each component comprises at least one of font, font size, color and arrangement of colors of contents contained in each component.

7. The apparatus of claim 6, wherein the document style converting unit converts the presentation style according to at least one of the attributes of each component, importance of each component, and the user'"'"'s profile.

8. The apparatus of claim 6, wherein the layout converting unit converts the size of the display region of each component and the amount of contents displayed in the display region of the component according to at least one of the user'"'"'s profile and an enlargement rate of the component.

9. The apparatus of claim 8, wherein, when the user enlarges a specified component to a specified enlargement rate, the layout converting unit adjusts the size of a display region of the enlarged component and the amount of contents displayed in the display region of the enlarged component and overlays the document with the specified component having the adjusted display region and the adjusted amount of contents.

10. The apparatus of claim 8, wherein, when the user enlarges a specified component to a specified enlargement rate, the layout converting unit adjusts sizes of display regions of the enlarged component and the remaining components and amounts of contents displayed in the display regions of the enlarged component and the remaining components to display all components on the display device.

11. An adaptive document displaying method comprising:

analyzing each of a plurality of components included in a document; and

converting the document according to the result of analysis and attributes of a display device.

12. The method of claim 11, wherein the analyzing of each component comprises:

creating a document tree which represents the hierarchical relationships between the components and comprises a plurality of nodes corresponding to the components, respectively; and

creating summary information of each component.

13. The method of claim 12, wherein the creating of the document tree comprises assigning attributes of each component to a corresponding node, wherein the attributes of each component comprise at least one of layout, presentation style and content format of the component.

14. The method of claim 13, wherein the creating of the document tree comprises calculating a priority of each component based on the attributes of the component, a user'"'"'s profile and the attributes of the display device.

15. The method of any one of claims 12 through 14, wherein the creating of the summary information comprises adding various lengths of summary information to each node of the created document tree in order to adjust the amount of contents which are to be displayed in a display region of a component corresponding to the node.

16. The method of claim 11, wherein the converting of the document comprises:

converting presentation style of each component according to the attributes of the display device; and

converting a size of a display region of each component and converting the amount of contents, which are to be displayed in the display region of the component, according to the size of the display region of the component,

wherein the presentation style of each component comprises at least one of font, font size, color and arrangement of colors of contents contained in each component.

17. The method of claim 16, wherein the converting of the presentation style comprises converting the presentation style of each component according to at least one of the attributes of each component, importance of the component, and the user'"'"'s profile.

18. The method of claim 16, wherein the converting of the size of the display region of each component and the amount of contents comprises converting the size of the display region of each component and the amount of contents displayed in the display region of the component according to at least one of the user'"'"'s profile and an enlargement rate of the component.

19. The method of claim 18, wherein, when the user enlarges a specified component to a specified enlargement rate, the converting of the size of the display region of each component and the amount of contents comprises adjusting the size of a display region of the enlarged component and the amount of contents displayed in the display region of the enlarged component and overlaying the document with the specified component having the adjusted display region and the adjusted amount of contents.

20. The method of claim 18, wherein, when the user enlarges a specified component to a specified enlargement rate, the converting of the size of the display region of each component and the amount of contents comprises adjusting sizes of display regions of the enlarged component and the remaining components and amounts of contents displayed in the display regions of the enlarged component and the remaining components to display all components on the display device.
