Methods and apparatus using long exposure video for virtual reality headset

1. A video apparatus comprising:

a video camera to capture first, real time video of a scene using a first field of view while operating using a first exposure time period, the first field of view corresponding to a first horizontal quantity of field of view degrees and a first vertical quantity of field of view degrees, the first exposure time period being at least twice as long as a second exposure time period, the second exposure time period corresponding to a normal exposure period of a human eye;

a field of view reducer to process the first video into second video after capture of the first video, the second video exhibiting a second field of view different from the first field of view, the second field of view corresponding to a second horizontal quantity of field of view degrees and the first vertical quantity of the field of view degrees, the second horizontal quantity smaller than the first horizontal quantity such that the second field of view is horizontally narrower than the first field of view; and

a head mounted display to display the second video at the first exposure time period with the second field of view in real-time.

2. The video apparatus as defined in claim 1 , wherein the head mounted display has a displayed field of view of the scene, the displayed field of view corresponding to the second horizontal quantity, the first field of view corresponding to the first horizontal quantity, the first field of view of the first video being wider than the displayed field of view of the head mounted display.

3. The video apparatus as defined in claim 2 , wherein the field of view reducer is to reduce the first field of view of the first video in accordance with the displayed field of view of the head mounted display.

4. The video apparatus as defined in claim 1 , wherein the head mounted display is coupled with the video camera to display the first video in substantially real time.

5. The video apparatus as defined in claim 2 , further including:

a recorder to record the first video; and

a player to playback the first video, the field of view reducer is to reduce the first field of view of the first video in accordance with the displayed field of view of the head mounted display.

6. The video apparatus as defined in claim 5 , wherein:

the head mounted display includes sensors to determine head movement; and

the head mounted display is to rotationally pan the displayed field of view relative to the scene of the first video based on the head movement determined by the sensors during playback.

7. The video apparatus as defined in claim 6 , wherein:

the first horizontal quantity is approximately one-hundred-and-eighty-degrees; and

the second horizontal quantity is approximately ninety degrees.

8. The video apparatus as defined in claim 6 , wherein:

the video camera is a head mounted video camera;

the recorder is to record head movement determined by the sensors during recording of the first video, the recording of head movement synchronized with the recording of the first field of view of the first video; and

the head mounted display is to rotationally pan the second field of view relative to the scene of the first video based on the head movement determined by the sensors during playback and adjusted based on the recording of the head movement during the first video.

9. The video apparatus as defined in claim 1 , wherein the video camera is a head mounted video camera mounted via a gimbal to ensure stability during capture of the first video of the scene.

10. A method comprising:

capturing first, real time video of a scene with a video camera using a first field of view while operating using a first exposure time period, the first field of view corresponding to a first horizontal quantity of field of view degrees and a first vertical quantity of field of view degrees, the first exposure time period being at least twice as long as a second exposure time period, the second exposure time period corresponding to a normal exposure period of a human eye;

processing the first video into second video after capture of the first video, the second video exhibiting a second field of view different from the first field of view, the second field of view corresponding to a second horizontal quantity of field of view degrees and the first vertical quantity of the field of view degrees, the second horizontal quantity smaller than the first horizontal quantity such that the second field of view is horizontally narrower than the first field of view; and

displaying the second video at the first exposure time period with the second field of view in real-time on a head mounted display.

11. The method as defined in claim 10 , further including:

reducing in substantially real time the first field of view of the first video to the second field of view to display the second video as a displayed field of view of the scene; and

displaying the displayed field of view of the scene substantially in real time.

12. The method as defined in claim 10 , further including:

determining head movement using sensors; and

rotationally panning the second video of the scene based on the head movement.

13. The method as defined in claim 12 , further including:

recording the head movement determined by the sensors during video recording; and

synchronizing the recording of the head movement during video recording and the recording of the first video, the rotationally panning of the second video of the scene in playback based on the head movement determined by the sensors during playback.

14. The method as defined in claim 10 , further including:

controlling flight of at least one drone within the scene; and

activating of at least one illuminator of the at least one drone.

15. A non-transitory machine readable storage medium comprising instructions that, when executed, cause a machine to at least:

capture first, real time video of a scene with a video camera at a first time using a first field of view while operating using a first exposure time period, the first field of view corresponding to a first horizontal quantity of field of view degrees and a first vertical quantity of field of view degrees, the first exposure time period being at least twice as long as a second exposure time period, the second exposure time period corresponding to a normal exposure period of a human eye;

process the first video into second video after capture of the first video, the second video exhibiting a second field of view different from the first field of view, the second field of view corresponding to a second horizontal quantity of field of view degrees and the first vertical quantity of the field of view degrees, the second horizontal quantity smaller than the first horizontal quantity such that the second field of view is horizontally narrower than the first field of view; and

display the second video at the first exposure time period with the second field of view in real time on a head mounted display.

16. The non-transitory machine readable storage medium as defined in claim 15 , wherein the instructions, when executed, cause the machine to:

determine head movement using sensors during playback display of the second video; and

rotationally pan the display of the second video based on the head movement.
