Abstract

A mobile terminal includes: a display unit; a sensing unit configured to detect an input signal; and a control unit configured to display a 360-degree video on the display unit and control the sensing unit to detect the input signal. In correspondence to a first input signal for playing the 360-degree video at a first playing angle, the control unit displays a first image played at the first playing angle on the display unit. When a second input signal for changing a playing angle of the 360-degree video to a second playing angle different from the first playing angle is detected, the control unit displays a second image played at the second playing angle as a main screen on the display unit and displays the first image played at the first playing angle as a PIP screen on the display unit.

First claim

What is claimed is:

1 . A mobile terminal comprising:
a display unit; a sensing unit configured to detect an input signal; and a control unit configured to:
detect, through the sensing unit, a first input signal for playing a 360-degree video at a first playing angle;
based on detecting the first input signal for playing the 360-degree video at the first playing angle, control the display unit to display a first image of the 360-degree video at the first playing angle;
detect, through the sensing unit, a second input signal for changing a playing angle of the 360-degree video to a second playing angle different from the first playing angle;
based on detecting the second input signal for changing the playing angle of the 360-degree video to the second playing angle different from the first playing angle:
display, as a main display area on the display unit, a second image of the 360-degree video at the second playing angle; and
display, as a portion of the main display area on the display unit, the first image of the 360-degree video played at the first playing angle.

2 . The mobile terminal of claim 1 , wherein the control unit is further configured to determine that the first playing angle has been designated as an optimized viewing angle by an original producer of the 360-degree video.

3 . The mobile terminal of claim 2 , wherein the control unit is further configured to determine that the first playing angle is within a predetermined angular range from the optimized viewing angle.

4 . The mobile terminal of claim 1 , wherein the control unit is further configured to:
determine that the second playing angle is outside of a predetermined angular range from the first playing angle; and based on the determination that the second playing angle is outside of the predetermined angular range from the first playing angle, display the first image as the portion of the main display area by:
controlling the display unit to display the first image played as a picture-in-picture (PIP) display within the main display area.

5 . The mobile terminal of claim 1 , wherein the control unit is further configured to:
based on the sensing unit detecting a third input signal for selecting the portion of the main display area in which the first image is displayed:
control the display unit to replace, as the main display area, the display of the second image played at the second playing angle with a display of the first image played at the first playing angle.

6 . The mobile terminal of claim 5 , wherein the control unit is further configured to:
based on replacing the display of second image as the main display area with the display of the first image played at the first playing angle as the main display area, control the display unit to terminate the display of the first image as the portion of the main display area.

7 . The mobile terminal of claim 1 , wherein the control unit is further configured to:
based on the sensing unit detecting a fourth input signal for switching the display of the main display area and the display of the portion of the main display area with each other, control the display unit to switch the display of the second image played at the second playing angle as the main display area with the display of the first image played at the first playing angle displayed as the portion of the main display area with each other.

8 . The mobile terminal of claim 1 , wherein the control unit is further configured to:
based on a degree to which the second playing angle differs from the first playing angle, control the display unit to change a size of the portion of the main display area displayed on the display unit.

9 . The mobile terminal of claim 1 , wherein the first image played at the first playing angle that is displayed as the portion of the main display area is a still image at a first view point; and
the control unit is further configured to:
based on the sensing unit detecting the second input signal for changing the playing angle of the 360-degree video to the second playing angle different from the first playing angle, control the display unit to switch the display of the first image to a display of a third image displayed at a third playing angle different from the first playing angle of the first view point.

10 . The mobile terminal of claim 1 , wherein the first playing angle is a playing angle that comprises a view of a first content of the 360-degree video that satisfies a viewing frequency criterion for a duration of a playback time of the 360-degree video, and
the control unit is further configured to:
based on a determination that the first content has not been displayed on the display unit for more than a predetermined duration of time, control the display unit to display the first image played at the first playing angle as the portion of the main display area on the display unit.

11 . The mobile terminal of claim 1 , wherein the first playing angle is a playing angle that satisfies a viewer recommendation criterion, and
the control unit is further configured to:
based on a determination that the first playing angle has not been displayed on the display unit for more than a predetermined duration of time, control the display unit to display the first image played at the first playing angle as the portion of the main display area on the display unit.

12 . The mobile terminal of claim 1 , wherein the first image played at the first playing angle displayed on the portion of the main display area is a still image at a first time point, and
the control unit is further configured to:
display a progress bar representing a playback time of the main display area on the display unit; and
based on a detection of an input signal for disposing the first image on the displayed progress bar, initiate a playback of the first image displayed as the portion of the main display area.

13 . The mobile terminal of claim 12 , wherein the control unit is further configured to:
based on the detection of the input signal for disposing the first image on the displayed progress bar, display, on the displayed progress bar, a playback time point indicator corresponding to the first image.

14 . The mobile terminal of claim 12 , wherein the control unit is further configured to:
based on a detection of an input signal for moving the first image out of the displayed progress bar, terminate the playback of the first image as the portion of the main display area.

15 . The mobile terminal of claim 1 , wherein the first playing angle is designated as an optimized viewing angle by an original producer of the 360-degree video, and
the control unit is further configured to:
based on a determination of a degree by which the second playing angle differs from the first playing angle, adjust a transparency of the portion of the main display area that displays the first image.

16 . The mobile terminal of claim 1 , wherein the control unit is further configured to:
based on a determination that the display of the first image played at the first playing angle is moved on the display unit as the first playing angle changes to the second playing angle, display, as a thumbnail on the display unit, an image played at a side that is opposite of a direction in which the display of the first image moves on the display unit.

17 . A method of operating a mobile terminal, the method comprising:
based on a first input signal for playing a 360-degree video at a first playing angle, displaying a first image played at the first playing angl
