Abstract

Camera related methods and apparatus which are well suited for use in capturing stereoscopic image data, e.g., pairs of left and right eye images, are described. Various features relate to a camera rig which can be used to mount multiple cameras at the same time. In some embodiments the camera rig includes 3 mounting locations corresponding to 3 different directions 120 degrees apart. One or more of the mounting locations may be used at a given time. When a single camera pair is used the rig can be rotated to capture images corresponding to the locations where a camera pair is not mounted. Static images from those locations can then be combined with images corresponding to the forward direction to generate a 360 degree view. Alternatively camera pairs or individual cameras can be included in each of the mounting locations to capture video in multiple directions.

Claims

1. A camera rig, said camera rig comprising:

a support structure including three mounting positions, each mounting position for mounting one or a pair of cameras, each mounting position corresponding to a different 120 degree direction;

a first pair of cameras mounted in a first one of said three mounting positions; and

a pair of left and right microphones each with an audio input positioned perpendicular to a face of a lens of a camera in the first pair of cameras.

2. The camera rig of claim 1, wherein said support structure includes a camera mounting plate, the camera rig further comprising:

a support tower to which said support structure is rotatably mounted.

3. The camera rig of claim 2, further comprising:

a second pair of cameras mounted in a second one of said three mounting positions.

4. The camera rig of claim 3, further comprising:

a third pair of cameras mounted in a third one of said three mounting positions.

5. The camera rig of claim 1, further comprising:

a single camera mounted in one of said three mounting positions.

6. A method of using a stereoscopic camera rig including at least a first pair of cameras, the method comprising:

capturing using a camera on the camera rig at least one rear image before an event;

capturing a first pair of images with the first pair of cameras mounted on a camera mounting platform of the rig at a first camera pair mounting position while the first pair of cameras is facing in a first direction;

capturing a second pair of images using a pair of cameras mounted on the camera mounting platform while the pair of cameras is facing in the second direction; and

transmitting pairs of images corresponding to said front direction captured in real time during the event and said at least one rear image captured before the event to a communications system or playback device while the event is ongoing.

7. The method of claim 6, further comprising:

capturing a third pair of images using a pair of cameras mounted on the camera mounting platform while the pair of cameras is facing in a third direction.

8. The method of claim 7, wherein capturing a second pair of images using a pair of cameras mounted on the camera mounting platform while the pair of cameras is facing in the second direction includes:

capturing the second pair of images with a second pair of cameras mounted on the camera mounting platform at a second camera pair mounting position.

9. The method of claim 8, wherein capturing a third pair of images using a pair of cameras mounted on the camera mounting platform while the pair of cameras is facing in the third direction includes:

capturing the third pair of images with a third pair of cameras mounted on the camera mounting platform at a third camera pair mounting position.

10. The method of claim 9, wherein capturing said first, second and third pairs of images includes capturing video using, in parallel, said first, second and third pairs of cameras.

11. The method of claim 10, wherein cameras included in each of the first, second and third pairs of cameras include fish eye lenses allowing the individual cameras of each of the first, second and third camera pairs to capture wide angle views.

12. The method of claim 9, wherein said first, second and third directions are 120 degrees apart from each other.

13. The method of claim 6, wherein the pair of cameras used to capture the second pair of images is said first pair of cameras, the method further comprising:

rotating the camera mounting platform, after capturing the first pair of images, to position the first pair of cameras to face in the second direction.

14. The method of claim 13, further comprising:

rotating the camera mounting platform after capturing the second pair of images to position the first pair of cameras to face in a third direction; and

capturing a third pair of images using the first pair of cameras while the first pair of cameras is facing in a third direction.

15. The method of claim 14, wherein said first, second and third directions are 120 degrees apart from each other.

16. The method of claim 15, wherein said first direction is a front direction and wherein stereoscopic pairs of images corresponding to said front direction are captured in real time by said first camera pair while an event is ongoing.

17. The method of claim 16, wherein said second and third directions are left and right rear directions.
