Abstract

A method of controlling a mobile terminal, and which includes entering, via a controller controlling a camera of the mobile terminal, a camera photograph mode; determining, via the controller of the mobile terminal, a position of a first pointer contacting a touchscreen in the camera photograph mode and whether the first pointer is in a first state or a second state when the first pointer is located in a preset region on the touchscreen; ignoring a touch input through the pointer, when the first pointer is determined as being in the first state; and performing a function corresponding to the touch input through the pointer, when the first pointer is determined as being in the second state.

Claims

1. A method of controlling a mobile terminal, the method comprising:

entering, via a controller controlling a camera of the mobile terminal, a camera photograph mode;

determining, via the controller of the mobile terminal, a position of a first pointer contacting a touchscreen in the camera photograph mode and whether the first pointer is in a first state or a second state when the first pointer is located in a preset region on the touchscreen,

wherein the first state corresponds to a motion of the first pointer being equal to or lower than a predetermined reference and the second state corresponds to the motion of the first pointer being greater than the predetermined reference;

ignoring a touch input through the pointer, when the first pointer is determined as being in the first state; and

performing a function corresponding to the touch input through the pointer, when the first pointer is determined as being in the second state.

2. The method of claim 1, wherein the first state corresponds to a motion of the first pointer being equal to or smaller than a first threshold value,

wherein the second state corresponds to the motion of the first pointer being equal to or greater than the first threshold value and a second threshold value, and

wherein if the motion of the first pointer in the second state is equal to or lower than the second threshold value and is maintained over a predetermined time, the determining step determines the first pointer is in the first state.

3. The method of claim 1, wherein the preset region includes an edge region of the touchscreen.

4. The method of claim 1, further comprising:

changing a position of a shutter button displayed on the touchscreen, when the first pointer is determined as being in the first state on the shutter button.

5. The method of claim 4, wherein changing the position of the shutter button comprises:

detecting whether a position of a second pointer on the touchscreen is changed; and

displaying the shutter button at the changed position, when the position of the second pointer is changed.

6. A method of controlling a mobile terminal, the method comprising:

displaying a preview image on a touchscreen by activating a camera;

determining a tracking target in the preview image,

wherein the tracking target is sensed by the camera; and

changing, via a controller of the mobile terminal, a photograph mode from a first mode to a second mode, when a motion of the determined tracking target is greater than a threshold value,

wherein the determining the tracking target comprises;

displaying a visual effect for specifying the tracking target in a prescribed configuration on the preview image; and

determining a subject included in the visual effect as the tracking target.

7. The method of claim 6, wherein the second photograph mode includes one of a burst mode and a video mode and the first photograph mode includes a still picture mode.

8. The method of claim 6, further comprising:

changing at least one of a size of the visual effect and a position of the visual effect.

9. A mobile terminal, comprising:

a wireless communication unit configured to provide wireless communication;

a camera configured to enter a camera photograph mode; and

a controller configured to;

determine a position of a first pointer contacting a touchscreen in the camera photograph mode and whether the first pointer is in a first state or a second state when the first pointer is located in a preset region on the touchscreen,

wherein the first state corresponds to a motion of the first pointer being equal to or lower than a predetermined reference and the second state corresponds to the motion of the first pointer being greater than the predetermined reference,

ignore a touch input through the pointer, when the first pointer is determined as being in the first state, and

perform a function corresponding to the touch input through the pointer, when the first pointer is determined as being in the second state.

10. The mobile terminal of claim 9, wherein the first state corresponds to a motion of the first pointer being equal to or smaller than a first threshold value,

wherein the second state corresponds to the motion of the first pointer being equal to or greater than the first threshold value and a second threshold value, and

wherein if the motion of the first pointer in the second state is equal to or lower than the second threshold value and is maintained over a predetermined time, the determining step determines the first pointer is in the first state.

11. The mobile terminal of claim 9, wherein the preset region includes an edge region of the touchscreen.

12. The mobile terminal of claim 9, wherein the controller is further configured to:

change a position of a shutter button displayed on the touchscreen, when the first pointer is determined as being in the first state on the shutter button.

13. The mobile terminal of claim 12, wherein the controller if further configured to:

detect whether a position of a second pointer on the touchscreen is changed, and

display the shutter button at the changed position, when the position of the second pointer is changed.

14. A mobile terminal, comprising:

a wireless communication unit configured to provide wireless communication;

a camera configured to sense a tracking target;

a touchscreen configured to display a preview image on a touchscreen by activating the camera; and

a controller configured to;

display a visual effect for specifying the tracking target in a prescribed configuration on the preview image,

determine a subject included in the visual effect as the tracking target, and

change photograph mode from a first mode to a second mode, when a motion of the determined tracking target is greater than a threshold value.

15. The mobile terminal of claim 14, wherein the second photograph mode includes one of a burst mode and a video mode and the first photograph mode includes a still picture mode.

16. The mobile terminal of claim 14, wherein the controller is further configured to:

change at least one of a size of the visual effect and a position of the visual effect.
