There is another idea for a rotating TV, but this didn't consider
the camera.
A conventional camera CCD is vertically rotated through the
image created by a conventional lens.
Edit: a CCD sensor has vertical axis at one end, and is rapidly
rotated around this point. The axis is at the nominal
focal length of
the lens. As the CCD is moved, it will swing through the image
created by the lens.
Some of the image will be
in focus at different parts of the rotation, and some will be out of
focus. The display, also rotating, but synchronised, displays 1:1
what the CCD sees.
It's a little difficult to imagine the result of very quickly overlaid
images at different locations, with different focus, but maybe it
will create an interesting 3D effect.

Maybe it will create an interesting effect - not even vaguely related...

Conventional wisdom says: yes. But different parts of a
lens receives light from the object at slightly different
angles. So, in this case wouldn't the 3D image be related
to the width of the lens? |

// missing the point about the "Rotating TV".// |
|

More likely, it's my lazy thumbs not wanting to explain
the detailed differences. It was related in mechanical
concept. |

Heh! |

I think that I would agree that I probably didn't explain it
well enough. |
|
| |
Let me try again: edited idea. |
|
| |
A little. Is that clearer? |
|
| |
A camera, with a CCD that spins around a vertical axis through its middle. One assumes a double-sided CCD. |
|
| |
So the image will be a bunch of horizontal streaks, the same sort of thing as if you rotated the entire camera, except limited to the bit in the nominal front, no ? or, how fast does it rotate. |
|
| |
I think it would need to rotate at approx 30 rps for flicker
free images, but as an experiment, could run slower. |
|
| |
I don't think the image would change as much as
spinning a normal camera around on its axis, at least
when the CCD is nearly perpendicular. |
|
| |
hmm... drop that down to a couple hundred RPM and you'd be seeing what a Leslie speaker sounds like. (you'd need some software to fudge doppler effect in the colour spectrum, though). |
