Abstract
A video synopsis method for overlapping videos generated in different periods is applied to a video synopsis device. The video synopsis method includes dividing a monitoring film into a plurality of videos, acquiring a pixel difference between frames respectively from the plurality of videos at identical time sequence, acquiring a weighting parameter according to the pixel difference, and utilizing the weighting parameter to overlap the frames respectively from the plurality of videos so as to generate a composite frame.
Claims18
A video synopsis method for overlapping videos generated in different periods, the video synopsis method comprising:
- dividing a monitoring film into a plurality of videos;
- acquiring a pixel difference between frames respectively from the plurality of videos at the same time sequence of each video;
- acquiring a weighting parameter according to the pixel difference;
- and
- utilizing the weighting parameter to overlap the frames respectively from different videos so as to generate a composite result.
A video synopsis device with a function of overlapping videos generated in different periods, the video synopsis device comprising:
- a video receiver adapted to receive a monitoring film;
- and
- an operation processor electrically connected to the video receiver, and adapted to divide a monitoring film into a plurality of videos, acquire a pixel difference between frames respectively from the plurality of videos at the same time sequence of each video, acquire a weighting parameter according to the pixel difference, and utilize the weighting parameter to overlap the frames respectively from different videos so as to generate a composite result, for condensing the plurality of videos of the monitoring film into a composite video.
