Abstract

A system and method used in an electronic apparatus for playing a video stored in the electronic apparatus via a display. The video playing system splits the video into a number of video segments. Each of the video segments has predetermined time duration. The video playing system analyzes each video segment to acquire image backgrounds and facial features of the video segments and delete a latter video segment of two adjacent video segments when the image backgrounds and the facial features of the latter video segment of two adjacent video segments is the same as the image backgrounds and the facial features of an earlier video segment of two adjacent video segments.

Claims

1. A video playing system of an electronic apparatus, the system comprising:

a video playing module configured to play a video;

a setup module configured to set a predetermined time duration;

a video splitting module configured to subdivide an unplayed portion of the video into a plurality of segments, each of the segments having the same predetermined time duration;

a video analyzing module configured to analyze each of the segments to acquire image backgrounds and facial features therefrom; and

a comparing module configured to compare the image backgrounds and facial features of each of two adjacent segments from a first segment to a last segment of the unplayed portion of the video;

wherein the comparing module is configured to control the video playing module to skip a latter segment of the two adjacent segments when the image backgrounds and facial features of these two adjacent segments are the same with each other.

2. The video playing system of claim 1, wherein the setup module further presets a predetermined time interval to detect a battery level value of the electronic apparatus and a plurality of predetermined correspondences between the battery level value of the electronic apparatus and the backlight brightness of the electronic apparatus.

3. The video playing system of claim 2, further comprising:

a battery detecting module that reads the battery level value of the electronic apparatus in the predetermined time interval; and

a backlight adjusting module adjusts a backlight brightness of the display according to the battery level value of the electronic apparatus and the predetermined correspondences between the battery level value of the electronic apparatus and the backlight brightness of the electronic apparatus.

4. The video playing system of claim 3, wherein the predetermined correspondences between the battery level value of the electronic apparatus and the backlight brightness of the electronic apparatus comprises the backlight brightness of the electronic apparatus is eighty percent of a maximum backlight brightness of the electronic apparatus when the battery level value of the electronic apparatus is more than about sixty percent of the maximum battery level value of the electronic apparatus and not more than about eighty percent of the maximum battery level value of the electronic apparatus, the backlight brightness of the electronic apparatus is sixty percent of the maximum backlight brightness of the electronic apparatus when the battery level value of the electronic apparatus is more than about fifty percent of the maximum backlight brightness of the electronic apparatus and not more than about sixty percent of the maximum backlight brightness of the electronic apparatus, and the backlight brightness of the electronic apparatus is fifty percent of the maximum backlight brightness of the electronic apparatus when the battery level value of the electronic apparatus is not more than fifty percent of the maximum backlight brightness of the electronic apparatus.

5. The video playing system of claim 3, further comprising:

a program managing module that reminds a user to shut down a plurality of background programs irrelevant to playing the video when the battery level value of the electronic apparatus is below a predetermined threshold battery level value.

6. The video playing system of claim 5, wherein the setup module further presets a predetermined threshold battery level value, the battery detecting module transmits a low power signal to the program managing module, and the program managing module displays a pop-up window to show a list of the background programs irrelevant to playing the video when receives the low power signal.

7. The video playing system of claim 1, wherein the video analyzing module employs an edge filtering algorithm, a Hough transform algorithm, and a face recognition algorithm to statistically analyze colors and gray scales of a plurality of pixels constituted of the images of each segment in order to acquire the image background and facial features of the segments.

8. The video playing system of claim 1, wherein the video playing system is embedded in a firmware of the storage device.

9. A video playing method for playing a video stored in an electronic apparatus, the method comprising:

presetting a predetermined time duration;

splitting an unplayed portion of the video into a plurality of segments, each of the segments having the same predetermined time duration;

analyzing each of the segments to acquire image backgrounds and facial features of the segments;

comparing the image backgrounds and facial features of each of two adjacent segments from a first segment to a last segment of the rest part of the have not been played; and

skipping a latter segment of the two adjacent segments when plays the rest part of the video have not been played if the image backgrounds and facial features of these two adjacent segments are the same as each other.

10. The method of claim 9, before the step of splitting a rest part of the video that has not been played into a plurality of video segments, further comprising:

presetting a predetermined threshold battery level value;

detecting a battery level value of the electronic apparatus 1;

executing the step of splitting an unplayed portion of the video that has not been played into a plurality of segments when the battery level value of the electronic apparatus is less than the predetermined threshold battery level value.

11. The method of claim 10, further comprising:

reminding a user to shut down the background programs irrelevant to playing the video when the battery level value of the electronic apparatus is less than the predetermined threshold battery level value.

12. The method of claim 9, further comprising:

presetting a predetermined time interval to detect a battery level value of the electronic apparatus and a plurality of predetermined correspondences between the battery level value of the electronic apparatus and the backlight brightness of electronic apparatus;

detecting the battery level value of the electronic apparatus in the predetermined time interval; and

adjusting the backlight brightness of electronic apparatus according to the battery level value of the electronic apparatus and the predetermined correspondences between the battery level value of the electronic apparatus and the backlight brightness of the display.

13. The method of claim 12, wherein the predetermined correspondences between the battery level value of the electronic apparatus and the backlight brightness of the display comprises the backlight brightness of the display is eighty percent of a maximum backlight brightness of the display when the battery level value of the electronic apparatus is more than about sixty percent of the maximum battery level value of the electronic apparatus and not more than about eighty percent of the maximum battery level value of the electronic apparatus, the backlight brightness of the display is sixty percent of the maximum backlight brightness of the display when the battery level value of the electronic apparatus is more than about fifty percent of the maximum backlight brightness of the display and not more than about sixty percent of the maximum backlight brightness of the display, and the backlight brightness of the display is fifty percent of the maximum backlight brightness of the display when the battery level value of the electronic apparatus is not more than fifty percent of the maximum backlight brightness of the display.

14. The method of claim 9, wherein an edge filtering algorithm, a Hough transform algorithm, and a face recognition algorithm are employed to statistically analyze colors and gray scales of a plurality of pixels constituted of the images of each video segment in order to acquire the image background and facial features of the video segments.
