Abstract

In order to make it possible to correct an object position so as to reduce a deviation in position of a detected object, a video display system ( 100 ) includes: a detection section ( 11 ) for detecting an object from a first video; a time interval estimation section ( 12 ) for estimating a time interval from when the first video is taken to when the object which has been detected by the detection section ( 11 ) is superimposed on a second video; and a first position correction section ( 13 ) for correcting a position of the object in the second video based on a moving speed of an imaging apparatus that takes the second video and the time interval which has been estimated by the time interval estimation section ( 12 ).

Claims (46)

1. A video display system, comprising at least one processor, the at least one processor carrying out:

a process of detecting an object from a first video;

a process of estimating a time interval from when the first video is taken to when the object which has been detected is superimposed on a second video; and

a process of correcting a position of the object in the second video based on a moving speed of an imaging apparatus that takes the second video and the time interval which has been estimated.

2. The video display system according to claim 1 , wherein:

the time interval includes a first delay time from when the first video is taken to when the first video is acquired.

3. The video display system according to claim 1 , wherein:

the time interval includes a second delay time that is taken to detect the object.

4. The video display system according to claim 1 , wherein:

the at least one processor further carries out a process of superimposing, on the second video, the object whose position has been corrected.

5. The video display system according to claim 4 , wherein:

in a case where the object is hidden by another object in the second video, the at least one processor superimposes the object on the second video in a mode in which the object is recognizable.

6. The video display system according to claim 4 , wherein:

the time interval includes a third delay time from when detection of the object is ended to when superimposition of the object is carried out.

7. The video display system according to claim 1 , wherein:

the at least one processor further carries out a process of further correcting the position of the object in the second video based on a moving speed of the object and the time interval which has been estimated.

8. A video display method, comprising:

detecting an object from a first video;

estimating a time interval from when the first video is taken to when the object which has been detected is superimposed on a second video; and

correcting a position of the object in the second video based on a moving speed of an imaging apparatus that takes the second video and the time interval.

9. The video display method according to claim 8 , wherein:

the time interval includes a first delay time from when the first video is taken to when the first video is acquired.

10. The video display method according to claim 8 , wherein:

the time interval includes a second delay time that is taken for the detecting of the object.

11. The video display method according to claim 8 , further comprising:

superimposing, on the second video, the object whose position has been corrected.

12. The video display method according to claim 11 , wherein:

in a case where the object is hidden by another object in the second video, in the superimposing of the object, the object is superimposed on the second video in a mode in which the object is recognizable.

13. The video display method according to claim 11 , wherein:

the time interval includes a third delay time from when detection of the object is ended to when superimposition of the object is carried out.

14. The video display method according to claim 8 , further comprising:

further correcting the position of the object in the second video based on a moving speed of the object and the time interval which has been estimated.

15. A video display apparatus, comprising at least one processor, the at least one processor carrying out:

a process of detecting an object from a first video;

a process of estimating a time interval from when the first video is taken to when the object which has been detected is superimposed on a second video; and

a process of correcting a position of the object in the second video based on a moving speed of an imaging apparatus that takes the second video and the time interval which has been estimated.

16. The video display apparatus according to claim 15 , wherein:

the time interval includes a first delay time from when the first video is taken to when the first video is acquired.

17. The video display apparatus according to claim 15 , wherein:

the time interval includes a second delay time that is taken to detect the object.

18. The video display apparatus according to claim 15 , wherein:

the at least one processor further carries out a process of superimposing, on the second video, the object whose position has been corrected.

19. The video display apparatus according to claim 18 , wherein:

the time interval includes a third delay time from when detection of the object is ended to when superimposition of the object is carried out.

20. The video display apparatus according to claim 15 , wherein:

the at least one processor further carries out a process of further correcting the position of the object in the second video based on a moving speed of the object and the time interval which has been estimated.
