Abstract

Disclosed are a content zooming method and a terminal implementing the same, in which content displayed on a screen can be zoomed based on a bending extent of the screen. The content zooming method in a terminal having a flexible display unit includes: displaying content on a screen of the flexible display unit; determining whether the content is a subject to be zoomed; calculating a bending extent of the screen by periods when the content is the subject to be zoomed; determining a zooming rate based on the bending extent calculated by periods; and zooming the content at the zooming rate.

Claims

1. A content zooming method in a terminal having a flexible display unit, the content zooming method comprising:

displaying a content on a screen of the flexible display unit;

determining whether the content is a subject to be zoomed;

calculating a bending extent of the screen by periods when the content is the subject to be zoomed;

determining a zooming rate by using the bending extent calculated by periods; and

zooming the content by at the zooming rate.

2. The content zooming method as claimed in claim 1, wherein in the determining of the zooming rate, a zoom-in rate is determined by using a bending angle of the screen when a bending form of the screen is convex, and a zoom-out rate is determined by using the bending angle of the screen when the bending form of the screen is concave.

3. The content zooming method as claimed in claim 1, further comprising:

determining whether the screen is flat, based on the bending extent calculated by periods; and

stopping zooming the content when the screen is flat.

4. The content zooming method as claimed in claim 1, further comprising:

stopping zooming the content when the content is zoomed out at a minimum magnification, or zoomed in at a maximum magnification.

5. The content zooming method as claimed in claim 1, wherein it is determined that the content is a subject to be zoomed when the content is one of a page of an electronic book, a web page, an electronic document, a text, a message, a map, a photograph, a preview and a video.

6. A content zooming method in a terminal having a flexible display unit, the content zooming method comprising:

displaying a content on a screen of the flexible display unit;

determining whether a magnification of the content is higher than a preset initial magnification;

determining whether the screen is concave based on a bending extent of the screen calculated by periods when the magnification of the content is higher than the initial magnification; and

zooming out the content at the initial magnification when the screen is concave.

7. The content zooming method as claimed in claim 6, further comprising:

determining whether the screen is convex based on the bending extent of the screen when the magnification of the content is lower than the initial magnification; and

zooming in the content at the initial magnification when the screen is convex.

8. A content zooming method in a terminal having a flexible display unit, the content zooming method comprising:

displaying a video on a screen of the flexible display unit;

determining whether the screen is convex, based on a bending extent calculated by periods; and

displaying the video on the whole screen when the screen is convex.

9. A terminal for zooming content, the terminal comprising:

a flexible display unit which displays the content on a screen;

a deformation sensing unit which detects deformation of the screen; and

a controller which controls the flexible display unit by using information on the deformation of the screen received from the deformation sensing unit,

wherein the controller determines whether the content is a subject to be zoomed, calculates a bending extent of the screen by periods by using the information on the deformation of the screen when the content is the subject to be zoomed, determines a zooming rate by using the bending extent calculated by periods, and zooms the content by using the zooming rate.

10. The terminal as claimed in claim 9, wherein the controller determines a zoom-in rate by using a bending angle of the screen when a bending form of the screen is convex, and a zoom-out rate by using the bending angle of the screen when the bending form of the screen is concave.

11. The terminal as claimed in claim 9, wherein the controller determines whether the screen is flat based on the bending extent calculated by periods, stops zooming the content when the screen is flat, and stops zooming the content when the content is zoomed out at a minimum magnification, or zoomed in at a maximum magnification.

12. The terminal as claimed in claim 9, wherein the controller determines that the content is the subject to be zoomed when the content is one of a page of an electronic book, a web page, an electronic document, a text, a message, a map, a photograph, a preview and a video.

13. A terminal comprising:

a flexible display unit which displays content on a screen;

a deformation sensing unit which detects deformation of the screen; and

a controller which controls the flexible display unit by using information on the deformation of the screen received from the deformation sensing unit,

wherein the controller determines whether the content is a subject to be zoomed, calculates a bending extent of the screen by periods based on the information on the deformation of the screen when the content is the subject to be zoomed, determines whether the content is displayed at a magnification higher than a preset initial magnification, determines whether the screen is concave based on the bending extent when the content is displayed at the magnification higher than the initial magnification, and zooms out the content at the initial magnification when the screen is concave.

14. The terminal as claimed in claim 13, wherein the controller determines whether the screen is convex based on the bending extent when the content is displayed at a magnification lower than the initial magnification, and zooms in the content at the initial magnification when the screen is convex.

15. A terminal comprising:

a flexible display unit which displays a video on a portion of a screen;

a deformation sensing unit which detects deformation of the screen; and

a controller which controls the flexible display unit by using information on the deformation of the screen received from the deformation sensing unit,

wherein the controller calculates a bending extent of the screen by periods based on the information on the deformation of the screen, determines whether the screen is convex based on the bending extent, and controls the flexible display unit to display the video on the whole screen.
