Abstract

A method and apparatus for controlling display mode switching based on the rotation pattern of a portable terminal prevents unwanted orientation changes in the display for certain movements. The display mode switching control method of the present invention includes extracting a rotation pattern including pitch, roll, and yaw angles of the terminal; determining whether the rotation pattern is a valid rotation pattern based on the angles; and switching, when the rotation pattern is the valid rotation pattern, from a current display mode to other display mode.

Claims

1. A display mode switching control method of a portable terminal, comprising:

extracting by a control unit a rotation pattern including at least one of pitch, roll, and yaw angles of the portable terminal;

determining by the control unit whether or not the rotation pattern is a valid rotation pattern based on a threshold value of at least two angles; and

switching, when the rotation pattern is the valid rotation pattern, from a current display mode to another display mode.

2. The display mode switching control method according to claim 1, wherein the determining of whether or not the rotation pattern is a valid rotation pattern is based on the threshold value of all three of the pitch, roll, and yaw angles of the portable terminal.

3. The display mode switching control method of claim 2, wherein extracting comprises:

checking whether an automatic display mode switching function is enabled; and

extracting, when the automatic display mode switching function is enabled, the rotation pattern.

4. The display mode switching control method of claim 1, wherein extracting comprises checking the rotation pattern at a predetermined period.

5. The display mode switching control method of claim 2, wherein determining comprises:

comparing each of the angles with a predetermined threshold angle; and

judging, when all of the angles are in a predetermined threshold angle range defined by the threshold angle, that the rotation pattern is the valid rotation pattern.

6. The display mode switching control method of claim 2, wherein determining comprises:

comparing each of the pitch, roll, and yaw angles with a respective predetermined threshold angle;

judging, when all of the angles are in a respective predetermined threshold angle range defined by the respective predetermined threshold angle, that the rotation pattern is the valid rotation pattern.

7. The display mode switching control method of claim 1, wherein determining comprises:

determining whether the yaw angle is in a predetermined threshold angle range; and

judging, when the yaw angle is in the predetermined threshold angle range, that the rotation pattern is the valid rotation pattern.

8. The display mode switching control method of claim 1, wherein switching comprises:

determining a target display mode based on the rotation pattern; and

switching, when the target display mode differs from the current display mode, from the current display mode to the target display mode.

9. The display switching control method of claim 1, wherein threshold angle for each of the pitch, roll and yaw angles is a user-changeable value.

10. A portable terminal comprising:

a sensing unit which extracts a rotation pattern including one or more of a pitch, a roll, and a yaw angles;

a display unit which displays a screen; and

a control unit which determines whether the rotation pattern is a valid rotation pattern based on at least one or more of the pitch, roll, and yaw angles and controls, when the rotation pattern is the valid rotation pattern, the display unit to switch from a current display mode to other display mode.

11. The portable terminal of claim 10, wherein the control unit determines whether the rotation pattern is a valid rotation pattern based on at least two of the pitch, roll, and yaw angles.

12. The portable terminal of claim 10, wherein the control unit determines whether the rotation pattern is a valid rotation pattern based on all of the pitch, roll, and yaw angles.

13. The portable terminal of claim 10, wherein the control unit checks whether an automatic display mode switching function is enabled and controls, when the automatic display mode switching function is enabled, the sensing unit to extract the rotation pattern.

14. The portable terminal of claim 10, wherein the sensing unit senses the rotation pattern at a predetermined period.

15. The portable terminal of claim 12, wherein the control unit compares each of the pitch, roll and yaw angles with a predetermined threshold angle and judges, when all of the angles are in a threshold angle range defined by the threshold angle, that the rotation pattern is the valid rotation pattern.

16. The portable terminal of claim 10, wherein the control unit determines whether the yaw angle is in a predetermined threshold angle range and judges, when the yaw angle is in the threshold angle range, that the rotation pattern is the valid rotation pattern.

17. The portable terminal of claim 10, wherein the control unit determines a target display mode based on the rotation pattern and switches, when the target display mode differs from the current display mode, from the current display mode to the target display mode.

18. The portable terminal of claim 15, wherein the predetermined threshold angle comprises a respectively different value for at least one of the pitch, roll and yaw angles.

19. The portable terminal of claim 15, wherein the predetermined threshold angle is a user-changeable value.

20. The portable terminal of claim 18, wherein the predetermined threshold angle for each of the pitch, roll and yaw angles is a user-changeable value.
