Abstract

A video processing method. A display region is provided according to a timeline, comprising at least one first sub-region with higher time resolution and one second sub-region with lower time resolution. A time scale value of the first sub-region is smaller than that of the second sub-region, and the first and second sub-regions have low-speed and medium-speed controls for scrolling forward and backward respectively. When a desired frame is located in the first sub-region, the low-speed or medium-speed control is scrolled to forward or backward on the timeline according to an operating command to locate the desired frame. When the desired frame is located in the second sub-region, the low-speed or medium-speed control is scrolled to forward or backward on the timeline according to an operating command to move the desired frame to the first sub-region.

Claims

1. A video processing method, comprising the steps of:

providing a display region according to a timeline, wherein the display region comprises at least one first sub-region and one second sub-region adjacent to the first sub-region, a time scale value of the first sub-region is smaller than that of the second sub-region, and the first and second sub-regions have low-speed and medium-speed controls with corresponding locations on the timeline for scrolling forward and backward respectively;

determining the location of a desired frame in the sub-region;

when the desired frame is located in the first sub-region, scrolling the low-speed or medium-speed control forward or backward on the timeline according to an operating command to locate the desired frame; and

when the desired frame is located in the second sub-region, scrolling the low-speed or medium-speed control forward or backward on the timeline according to an operating command to move the desired frame to the first sub-region.

2. The method as claimed in claim 1, wherein the display region further comprises a third sub-region, adjacent to the first or second sub-region.

3. The method as claimed in claim 2, wherein a time scale value of the third sub-region is greater than that of the first or second sub-regions, and the third sub-region has a high-speed control with a corresponding location on the timeline for scrolling forward and backward.

4. The method as claimed in claim 3, wherein when the desired frame is located in the third sub-region, the medium-speed or high-speed control is scrolled to forward or backward on the timeline according to an operating command to move the desired frame to the first or second sub-region.

5. A video editing interface, comprising:

a display region, comprising at least one first sub-region and two second sub-regions, wherein the first sub-region is between the two second sub-regions, a time scale value of the first sub-region is smaller than that of each second sub-region, and the first and each second sub-region have low-speed and medium-speed controls with corresponding locations on the timeline respectively for scrolling forward and backward.

6. The interface as claimed in claim 5, wherein when a desired frame is located in the first sub-region, the low-speed or medium-speed control is scrolled to forward or backward on the timeline according to an operating command to locate the desired frame.

7. The interface as claimed in claim 5, wherein when a desired frame is located in one second sub-region, the low-speed or medium-speed control is scrolled to forward or backward on the timeline according to an operating command to move the desired frame to the first sub-region.

8. The interface as claimed in claim 5, wherein the display region further comprises two third sub-regions, located respectively adjacent to the two second sub-regions.

9. The interface as claimed in claim 8, wherein a time scale value of each third sub-region is greater than that of the first sub-region or each second sub-region, and each third sub-region has a high-speed control with a corresponding location on the timeline for scrolling forward and backward.

10. The interface as claimed in claim 9, wherein when a desired frame is located in one third sub-region, the medium-speed or high-speed control is scrolled to forward or backward on the timeline according to an operating command to move the desired frame to the first or one second sub-region.

11. A storage medium for storing a computer program providing a method for automatic booting a computer system, comprising using a computer to perform the steps of:

providing a display region according to a timeline, wherein the display region comprises at least one first sub-region and one second sub-region adjacent to the first sub-region, a time scale value of the first sub-region is smaller than that of the second sub-region, and the first and second sub-regions have low-speed and medium-speed controls with corresponding locations on the timeline for scrolling forward and backward respectively;

determining the location of a desired frame in the sub-region;

when the desired frame is located in the first sub-region, scrolling the low-speed or medium-speed control forward or backward on the timeline according to an operating command to locate the desired frame; and

when the desired frame is located in the second sub-region, scrolling the low-speed or medium-speed control forward or backward on the timeline according to an operating command to move the desired frame to the first sub-region.

12. The storage medium as claimed in claim 11, wherein the display region further comprises a third sub-region, adjacent to the first or second sub-region.

13. The storage medium as claimed in claim 12, wherein a time scale value of the third sub-region is greater than that of the first or second sub-region, and the third sub-region has a high-speed control with a corresponding location on the timeline for scrolling forward and backward.

14. The storage medium as claimed in claim 13, wherein when the desired frame is located in the third sub-region, the medium-speed or high-speed control is scrolled to forward or backward on the timeline according to an operating command to move the desired frame to the first or second sub-region.

15. A video processing method, scrolling video data on a timeline for locating a desired frame, comprising the steps of:

providing a display region according to the timeline, wherein the display region comprises at least one first sub-region and one second sub-region adjacent to the first sub-region, a first time scale value corresponding to the first sub-region is different from a second time scale value of the second sub-region, the first and second sub-regions have controllers corresponding to the first and second time scale values respectively; and

scrolling the video data using the controllers on the timeline in accordance with the first and second time scale values respectively according to operating commands.
