Abstract

Disclosed is a portable terminal and a method for driving the portable terminal, the portable terminal including a camera module capturing an image of an object, a position information obtaining sensor detecting a motion of the portable terminal, and a controller driving the camera module using the motion of the portable terminal detected by the position information obtaining sensor.

Claims

1. A portable terminal, the portable terminal comprising:

a camera module capturing an image of an object;

position information obtaining sensors detecting a first motion of the portable terminal or a second motion of the portable terminal;

a storage in which data corresponding to a first particular motion for turning-on the camera module and a second particular motion for turning-off the camera module is pre-stored; and

a controller configured to control turning-on or turning-off the camera module using the first motion or the second motion of the portable terminal detected by the position information obtaining sensors, respectively,

wherein the controller is configured to turn on or turn off the camera module when it is determined that the first motion or the second motion of the portable terminal and the first particular motion or the second particular motion, respectively, are identical by comparing data corresponding to the first motion or the second motion of the portable terminal with the data corresponding to the first particular motion or the second particular motion, respectively, pre-stored in the storage.

2. The portable terminal of claim 1, wherein the camera module includes a camera module driving unit driving the camera module, a power source supplying a voltage to the camera module driving unit, and a switching unit interposed between the camera module driving unit and the power source to switch the voltage supplied from the power source using the control signal from the controller.

3. The portable terminal of claim 2, wherein the switching unit supplies voltage to the camera module driving unit from the power source using the control signal of the controller, or interrupts the voltage supplied to the camera module using the control signal of the controller.

4. The portable terminal of claim 1, wherein the driving of the camera module is to turn on the camera module.

5. The portable terminal of claim 1, wherein the driving of the camera module is to turn off the camera module.

6. The portable terminal of claim 1, wherein the position information obtaining sensors include an acceleration sensor sensing each angular velocity of X, Y, Z and a tilt to each direction.

7. The portable terminal of claim 6, wherein the position information obtaining sensors include a gyro sensor sensing a direction rotated to a standard direction.

8. The portable terminal of claim 1, wherein the first motion or the second motion of the portable terminal includes a motion of the portable terminal being rotated.

9. The portable terminal of claim 1, wherein the first motion or the second motion of the portable terminal includes a motion of the portable terminal being moved.

10. A method for driving a portable terminal, the method comprising:

detecting, by position information obtaining sensors, a first motion of the portable terminal or a second motion of the portable terminal;

comparing data corresponding to the first motion or the second motion of the portable terminal detected by the position information obtaining sensors with data corresponding to a first particular motion for turning-on a camera module and a second particular motion for turning-off the camera module pre-stored in a storage; and

turning on or turning off a camera module when it is determined that the first motion or the second motion of the portable terminal detected by the position information obtaining sensors and the first particular motion or second particular motion, respectively, pre-stored in the storage are identical.

11. The method of claim 10, wherein the step of turning on or turning off the camera module includes determining whether the captured motion is released, in case the camera module is turned on, and turning off the camera module, in case the captured motion is released.

12. The method of claim 10, wherein the first particular motion or the second particular motion of the portable terminal includes a motion to rotate the portable terminal, or a motion to horizontally or vertically move the portable terminal.

13. The method of claim 12, wherein the step of turning on or turning off the camera module includes determining whether the captured motion is released, in case the camera module is turned on, and turning off the camera module, in case the captured motion is released.

14. The method of claim 11, wherein the first particular motion or the second particular motion of the portable terminal includes a motion of the portable terminal being rotated or moved.
