Abstract

A video editing apparatus capable of generating edited video data includes a video data selection unit configured to select a plurality of pieces of video data based on a set selection condition, an estimation unit configured to estimate correlation between video frames of the plurality of pieces of the video data selected by the video data selection unit, a cut-point setting unit configured to set the video frames estimated with a predetermined high correlation by the estimation unit as a cut-point, if the plurality of pieces of the video data selected by the video data selection unit are connected, and a generation unit configured to connect the plurality of pieces of the video data selected by the video data selection unit based on the cut-point set by the cut-point setting unit, and generate the edited video data.

Claims

1. A video editing apparatus capable of generating edited video data, the video editing apparatus comprising:

a video data selection unit configured to select a plurality of pieces of video data based on a set selection condition;

an estimation unit configured to estimate correlation between video frames of the plurality of pieces of the video data selected by the video data selection unit;

a cut-point setting unit configured to set the video frames estimated with a predetermined high correlation by the estimation unit as a cut-point, if the plurality of pieces of the video data selected by the video data selection unit are connected; and

a generation unit configured to connect the plurality of pieces of the video data selected by the video data selection unit based on the cut-point set by the cut-point setting unit, and generate the edited video data.

2. The video editing apparatus according to claim 1, wherein the estimation unit estimates the predetermined correlation based on continuity of motion of an object between the video frames, if a similar motion of the object is detected between the video frames.

3. The video editing apparatus according to claim 1, wherein the estimation unit estimates the predetermined correlation based on similarity of movement direction of an object between the video frames, if movement of the object is detected between the video frames.

4. The video editing apparatus according to claim 1, wherein the estimation unit estimates the predetermined correlation based on similarity of position of an object between the video frames, if the object is detected between the video frames.

5. The video editing apparatus according to claim 1, wherein the estimation unit estimates the predetermined correlation based on similarity of a line-of-sight direction of an object in preceding video data and a direction of the object in following video data in the plurality of pieces of the video data.

6. A method of video editing for generating edited video data, the method comprising:

selecting a plurality of pieces of video data based on a set selection condition;

estimating correlation between video frames of the selected plurality of pieces of the video data;

setting the video frames estimated with a predetermined high correlation as a cut-point, if the selected plurality of pieces of the video data are connected; and

connecting the selected plurality of pieces of the video data based on the set cut-point, and generating the edited video data.

7. The method according to claim 6, wherein the predetermined correlation is based on continuity of motion of an object between the video frames, if a similar motion of the object is detected between the video frames.

8. The method according to claim 6, wherein the predetermined correlation is based on similarity of movement direction of an object between the video frames, if movement of the object is detected between the video frames.

9. The method according to claim 6, wherein the predetermined correlation is based on similarity of position of an object between the video frames, if the object is detected between the video frames.

10. The method according to claim 6, wherein the predetermined correlation is based on similarity of a line-of-sight direction of an object in preceding video data and a direction of the object in following video data in the plurality of pieces of the video data.

11. A computer-readable recording medium recording a program for realizing the method according to claim 6 with a computer.
