Abstract

Disclosed are a mobile terminal and a method for controlling a 3D multi-angle view thereof. Multi-angle views of a 3D image captured by a plurality of cameras are displayed, switched (converted) and selected according to a touch input. And, a selected angle view of the 3D image undergoes a capturing or a recording. While appreciating different-angle views of a 3D image (broadcast image) captured by a plurality of cameras, a desired angle view of the 3D image may be played, recorded and stored with using a user interface. This may enhance a user'"'"'s convenience.

receiving a motion of the mobile terminal; and

switching the displayed multi-angle views according to the received input and motion.

10. The method of claim 9, wherein:

the input related to the displayed multi-angle views comprises a key input, a proximity touch input or a direct touch input; and

the proximity touch input and the direct touch input comprise a single touch, a touch and drag or a flicking touch.

11. The method of claim 9, further comprising:

implementing at least one multi-angle view of the multi-angle views as a segregated view;

displaying at least one bidirectional switching icon at right and left sides of the multi-angle views;

receiving an input comprising a touch of the at least one bidirectional switching icon, a touch and flick of the bidirectional switching icon, touching of one or more numeric keys, touching one or more numeric buttons or movement of the mobile terminal in the X, Y or Z direction; and

switching the at least one multi-angle view in response to the received input.

12. The method of claim 9, further comprising:

implementing at least one multi-angle view of the multi-angle views as a picture-in-picture (PIP) angle view; and

switching the PIP angle view of at the least one multi-angle view at a predetermined time interval.

13. The method of claim 9, further comprising:

implementing at least one multi-angle view of the multi-angle views as a stadium view;

receiving a direct touch on the display screen or a rotation degree of the mobile terminal; and

switching the at least one multi-angle view in response to the received direct touch or rotation degree.

14. The method of claim 9, further comprising:

implementing at least one multi-angle view of the multi-angle views as a gallery view;

displaying at least one angle switch icon on the display screen;

receiving a touch in one direction of the displayed at least one angle switch icon; and

switching the at least one multi-angle view in response to the received touch.

15. A mobile terminal, comprising:

a touch screen configured to display a three-dimensional (3D) stereoscopic image including a multi-angle;

a sensing unit configured to sense a touch input on the touch screen; and

a controller configured to;

control the touch screen to display a first 3D stereoscopic image including a multi-angle;
