The original video includes a plurality of original frames. The video processing method includes the following steps: A dynamic object is detected in the original video and a plurality of interesting regions in some of the original frames is obtained according to the dynamic object. Some of the original frames are cropped to obtain a plurality of cropped sub-frames according to the interesting regions. Each of the cropped sub-frames is resized to obtain a plurality of resized sub-frames whose resolutions are identical. The resized sub-frames are compressed to be an interesting video. ## Claims ### Claim 1 A video processing method, for processing an original video including a plurality of original frames, wherein the video processing method comprises: detecting a dynamic object in the original video and obtaining a plurality of interesting regions in some of the original frames according to the dynamic object; cropping some of the original frames to obtain a plurality of cropped sub-frames according to the interesting regions; resizing each of the cropped sub-frames to obtain a plurality of resized sub-frames whose resolutions are identical; and compressing the resized sub-frames to be an interesting video. ### Claim 2 (depends on 1) The video processing method according to claim 1, wherein the interesting regions are not located at the same location in the original frames. ### Claim 3 (depends on 1) The video processing method according to claim 1, wherein the original video is captured by a video camera whose image taking direction is fixed, and the interesting regions are moved along with the dynamic object. ### Claim 4 (depends on 1) The video processing method according to claim 1, wherein the original video is captured by a video camera whose zooming rate is fixed. ### Claim 5 (depends on 1) The video processing method according to claim 1, wherein the resolutions of the cropped sub-frames are not identical. ### Claim 6 (depends on 1) The video processing unit according to claim 1, wherein the resolution of each of the resized sub-frames is less than the resolution of each of the original frames. ### Claim 7 A video processing system, for processing an original video including a plurality of original frames, wherein the video processing system comprises: a detecting unit for detecting a dynamic object in the original video and obtaining a plurality of interesting regions in some of the original frames according to the dynamic object; a cropping unit for cropping some of the original frames to obtain a plurality of cropped sub-frames according to the interesting regions; a resizing unit for resizing each of the cropped sub-frames to obtain a plurality of resized sub-frames whose resolutions are identical; and a compressing unit for compressing the resized sub-frames to be an interesting video. ### Claim 8 (depends on 7) The video processing system according to claim 7, wherein the interesting regions are not located at the same location in the original frames. ### Claim 9 (depends on 7) The video processing system according to claim 7, further comprising a video camera for capturing the original video, wherein an image taking direction of the video camera is fixed, and the interesting regions are moved along with the dynamic object. ### Claim 10 (depends on 7) The video processing system according to claim 7, further comprising a video camera for capturing the original video, wherein a zooming rate of the video camera is fixed. ### Claim 11 (depends on 7) The video processing system according to claim 7, wherein the resolutions of the cropped sub-frames are not identical. ### Claim 12 (depends on 7) The video processing system according to claim 7, wherein the resolution of each of the resized sub-frames is less than the resolution of each of the original frames.
