Abstract

The present invention relates to a method and apparatus for visualizing information of a digital video stream is disclosed. The apparatus comprises: a memory arranged to store a series of merged image frames which is formed by merging groups of image frames of the digital video stream; a blending module arranged to blend multiple merged frames into a series of blended image frames, wherein each of a plurality of the merged image frames contributes to a plurality of the blended image frames; and a display arranged to display the series of blended image frames.

First claim

What is claimed is:

1 . A method for visualizing information of a digital video stream, the method comprising:
receiving a series of merged image frames which is formed by merging groups of image frames of the digital video stream; blending multiple merged frames into a series of blended image frames, wherein each of a plurality of the merged image frames contributes to a plurality of the blended image frames; and displaying, on a display, the series of blended image frames.

2 . The method according to claim 1 , further comprising setting number of image frames contributing to each merged frame.

3 . The method according to claim 1 , further comprising setting number of merged image frames contributing to each blended image frame.

4 . The method according to claim 1 , wherein a merged image frame contributing weight is set to change between at least two of the blended image frames to which the merged image frame contributes.

5 . The method according to claim 1 , wherein a merged image frame contributing weight is set to be constant for each of the blended image frames to which the merged image frame contributes.

6 . The method according to claim 1 , wherein the displaying of the series of blended image frames is performed by displaying the blended image frames consecutively as a video stream of blended image frames.

7 . The method according to claim 1 , wherein the displaying of the series of blended image frames is performed by displaying the blended image frames side by side on the display.

8 . The method according to claim 1 , further comprising merging groups of image frames of the digital video stream into the series of merged image frames.

9 . The method according to claim 8 , further comprising reducing the resolution of the image frames before merging groups of image frames from the video stream into the series of merged image frames.

10 . The method according to claim 8 , further comprising reducing the resolution of the image frames upon merging groups of image frames from the video stream into the series of merged image frames.

11 . The method according to claim 8 , further comprising detecting an event of interest in the digital video stream and setting an image frame contributing weight for an image frame of the digital video stream comprising the event differently than an image frame contributing weight for an image frame of the digital video stream not comprising the event.

12 . The method according to claim 1 , further comprising detecting an event of interest in the digital video stream and setting a merged image frame contributing weight for a merged image frame comprising the event differently than a merged image frame contributing weight for a merged image frame not comprising the event.

13 . An apparatus for visualizing information of a digital video stream, the apparatus comprising:
a memory arranged to store a series of merged image frames which is formed by merging groups of image frames of the digital video stream; a blending module arranged to blend multiple merged frames into a series of blended image frames, wherein each of a plurality of the merged image frames contributes to a plurality of the blended image frames; and a display arranged to display the series of blended image frames.

14 . The apparatus according to claim 13 , further comprising a merging module arranged to merge groups of image frames from the digital video stream into the series of merged image frames.

15 . A non-transitory computer readable recording medium configured to store a set of instructions that, when executed on a device having processor capabilities, cause the device to perform a method for visualizing information of a digital video stream, the method comprising:
receiving a series of merged image frames which is formed by merging groups of image frames of the digital video stream; blending multiple merged frames into a series of blended image frames, wherein each of a plurality of the merged image frames contributes to a plurality of the blended image frames; and displaying, on a display, the series of blended image frames.
