Abstract

A method for displaying a video, a mobile electronic device thereof and a storage medium thereof. In the present method, first, the video is displayed on a screen of the mobile electronic device. Then, an acceleration variance of the mobile electronic device is detected through a sensor of the mobile electronic device. Next, a display area of the video in the screen is adjusted according to the acceleration variance. As a result, a user can comfortably watch the video displayed in the screen of the mobile electronic device even in an unstable state.

Claims

1. A video display method, suitable for a mobile electronic device having a motion sensor, the video display method comprising:

displaying a video on a screen of the mobile electronic device;

detecting an acceleration variance of the mobile electronic device through the sensor; and

adjusting a display area of the video in the screen according to the acceleration variance.

2. The video display method according to claim 1, wherein the step of adjusting the display area of the video in the screen according to the acceleration variance comprises:

identifying a direction corresponding to the acceleration variance; and

moving the display area in the screen toward a second direction substantially opposite to the direction.

3. The video display method according to claim 2, wherein the step of moving the display area in the screen toward the second direction comprises:

identifying a force corresponding to the acceleration variance;

calculating a displacement according to the force and an adjustment ratio; and

moving the display area toward the second direction according to the displacement.

4. The video display method according to claim 3, wherein after the step of identifying the force corresponding to the acceleration variance, the video display method further comprises:

moving the display area close to a specific side of the screen if the force exceeds a predetermined value, wherein the specific side is substantially opposite to the direction corresponding to the acceleration variance.

5. The video display method according to claim 3 further comprising:

serving a predetermined area in the screen as the display area when the mobile electronic device does not have the acceleration variance or the force corresponding to the acceleration variance is 0.

6. The video display method according to claim 5, wherein the predetermined area comprises a central area.

7. The video display method according to claim 1 further comprising:

filling up areas in the screen other than the display area with a predetermined color.

8. A mobile electronic device, comprising:

a screen;

a video display module, coupled to the screen for playing a video in the screen; and

a sensor, coupled to the video display module for detecting an acceleration variance of the mobile electronic device, wherein

the video display module adjusts a display area of the video displayed on the screen according to the acceleration variance.

9. The mobile electronic device according to claim 8, wherein the video display module obtains a direction corresponding to the acceleration variance and moves the display area in the screen toward a second direction substantially opposite to the direction.

10. The mobile electronic device according to claim 9, wherein the video display module obtains a force corresponding to the acceleration variance, calculates a displacement according to the force and an adjustment ratio, and moves the display area toward the second direction according to the displacement.

11. The mobile electronic device according to claim 10, wherein the video display module moves the display area close to a specific side of the screen when the force exceeds a predetermined value, wherein the specific side is substantially opposite to the direction corresponding to the acceleration variance.

12. The mobile electronic device according to claim 10, wherein the video display module serves a predetermined area in the screen as the display area when the mobile electronic device does not have the acceleration variance or the force corresponding to the acceleration variance is 0.

13. The mobile electronic device according to claim 12, wherein the predetermined area comprises a central area.

14. The mobile electronic device according to claim 8, wherein the video display module fills up areas in the screen other than the display area with a predetermined color.

15. A storage medium, for storing a computer program, wherein the computer program comprises a plurality of program codes and is suitable for being loaded into a mobile electronic device with a sensor to allow the mobile electronic device to execute:

displaying a video on a screen of the mobile electronic device;

detecting an acceleration variance of the mobile electronic device through the sensor; and

adjusting a display area of the video in the screen according to the acceleration variance.

16. The storage medium according to claim 15, wherein the step of adjusting the display area of the video in the screen according to the acceleration variance comprises:

identifying a direction corresponding to the acceleration variance; and

moving the display area in the screen toward a second direction substantially opposite to the direction.

17. The storage medium according to claim 16, wherein the step of moving the display area in the screen toward the second direction comprises:

identifying a force corresponding to the acceleration variance;

calculating a displacement according to the force and an adjustment ratio; and

moving the display area toward the second direction according to the displacement.

18. The storage medium according to claim 17, wherein after the step of identifying the force corresponding to the acceleration variance, the mobile electronic device further executes:

moving the display area close to a specific side of the screen when the force exceeds a predetermined value, wherein the specific side is substantially opposite to the direction corresponding to the acceleration variance.

19. The storage medium according to claim 17 further comprising:

serving a predetermined area in the screen as the display area when the mobile electronic device does not have the acceleration variance or the force corresponding to the acceleration variance is 0.

20. The storage medium according to claim 15 further comprising:

filling up areas in the screen other than the display area with a predetermined color.
