Abstract

A method for displaying an image in a wireless terminal including at least two screen modes is provided, in which a display buffer existing in one Device Context (DC) is formed, capable of recording a corresponding image to be displayed according to screen sizes in the at least two screen modes, and recording the corresponding image to be displayed according to a screen size of a corresponding screen mode in the at least two screen modes through the display buffer existing in the DC, and outputting the corresponding image to a screen in the corresponding screen mode.

Claims

1. A method for displaying an image in a wireless terminal comprising at least two screen modes, the method comprising:

forming a display buffer in one Device Context (DC) for recording a corresponding image to be displayed according to screen sizes in at least two screen modes;

recording the corresponding image to be displayed according to a screen size of a corresponding screen mode of said at least two screen modes through the display buffer in the DC; and

outputting the corresponding image to a screen in the corresponding screen mode.

2. The method as claimed in claim 1, wherein a size of the display buffer comprises all screen sizes in said at least two screen modes.

3. The method as claimed in claim 2, wherein the display buffer comprises an area shared by the screen sizes in said at least two screen modes and corresponding areas for the screen sizes in said at least two screen modes.

4. The method as claimed in claim 1, wherein the display buffer comprises a first area shared by the screen sizes in said at least two screen modes and a second area logically added to a location of the first area, said second area corresponding to the screen size in the corresponding screen mode of said at least two screen modes.

5. The method as claimed in claim 4, wherein the second area is logically added to at least one of an upper side, a lower side, a left side and a right side of the first area.

6. The method as claimed in claim 4, wherein the second area comprises a plurality of areas.

7. A method for displaying an image in a wireless terminal comprising a first and second screen modes, the method comprising:

forming a display buffer in one Device Context (DC) for recording a corresponding image to be displayed according to screen sizes in a first and the second screen modes;

determining if the wireless terminal is in at least one of the first screen mode and the second screen mode;

when the wireless terminal is in the first screen mode, recording a corresponding image in a first area shared by the screen sizes in the first and the second screen modes, and a third area for the screen size in the first screen mode in the display buffer in the DC, and outputting the corresponding image to a screen in the first screen mode; and

when the wireless terminal is in the second screen mode, recording a corresponding image in the first area shared by the screen sizes in the first and the second screen modes, and a second area for the screen size in the second screen mode in the display buffer in the DC, and outputting the corresponding image to a screen in the second screen mode.

8. The method as claimed in claim 7, wherein the display buffer comprises the first area, which are shared by the screen sizes in the first and the second screen modes, the second area for the screen size in the second screen mode, and the third area for the screen size in the first screen mode.

9. The method as claimed in claim 7, wherein the first and the second screen modes are determined according to whether a folder of the wireless terminal comprises at least one of opened, closed and rotated configurations.

10. The method as claimed in claim 7, wherein, when the first screen mode comprises a portrait screen mode, recording the corresponding image in the first area shared by the screen sizes in the first and the second screen modes, and the third area for the screen size in the first screen mode located at a lower side of the first area, in the display buffer, and outputting the corresponding image to the screen in the first screen mode.

11. The method as claimed in claim 7, wherein, when the second screen mode comprises a landscape screen mode, recording the corresponding image in the first area shared by the screen sizes in the first and the second screen modes and the second area for the screen size in the second screen mode located at a right side of the first area, in the display buffer, and outputting the corresponding image to the screen in the second screen mode.

12. A method for displaying an image in a wireless terminal comprising a first and second screen modes, the method comprising:

forming a display buffer in one Device Context (DC) for recording a corresponding image to be displayed according to screen sizes in a first and the second screen modes;

determining if the wireless terminal is in at least one of the first screen mode and the second screen mode;

when the wireless terminal is in the first screen mode, recording a corresponding image in a first area shared by the screen sizes in the first and the second screen modes, and a second area logically added to a location of the first area in order to correspond to the screen size in the second screen mode, in the display buffer in the DC, and outputting the corresponding image to a screen in the first screen mode; and

when the wireless terminal is in the second screen mode, recording a corresponding image in both the first area shared by the screen sizes in the first and the second screen modes, and the second area logically added to the location of the first area in order to correspond to the screen size in the second screen mode, in the display buffer in the DC, and outputting the corresponding image to a screen in the second screen mode.

13. The method as claimed in claim 12, wherein the display buffer comprises the first area shared by the screen sizes in the first and the second screen modes, and the second area logically added to the location of the first area in order to correspond to a screen size in a corresponding screen mode.

14. The method as claimed in claim 13, wherein the second area comprises a plurality of areas.

15. The method as claimed in claim 13, wherein the second area comprises a single area.

16. The method as claimed in claim 12, wherein the first and the second screen modes are determined according to whether a folder of the wireless terminal comprises at least one of opened, closed and rotated configurations.

17. The method as claimed in claim 12, wherein the outputting of the corresponding image to the screen in the first screen mode comprises:

when the first screen mode is a portrait screen mode, logically adding the second area to a lower side of the first area in the display buffer, which is shared by the screen sizes in the first and the second screen modes, thereby forming the display buffer;

recording the corresponding image in the first area and the second area; and

outputting the corresponding image to the screen in the first screen mode.

18. The method as claimed in claim 12, wherein the outputting of the corresponding image to the screen in the second screen mode comprises:

when the second screen mode is a landscape screen mode, logically adding the second area to a right side of the first area in the display buffer, which is shared by the screen sizes in the first and the second screen modes, thereby forming the display buffer;

recording the corresponding image in the first area and the second area; and

outputting the corresponding image to the screen in the second screen mode.

19. The method as claimed in claim 18, wherein the corresponding image recorded in the second area is recorded in a direction in which the corresponding image is recorded in a physical memory.
