Re: Pinhole scanner

Hi

Andrew Davidhazy's scanner camera info is at:

A scanner is actually a very specialized digital strip camera. Its designed to construct a
digital image (much like a circuit camera) of a piece of paper as the scanner element moves
below the paper.

To get these to work as a camera one would have to disable to interior illumination

If anyone ever gets a scanner converted to a camera it would be cool to modify the imaging
element movement so that it rotates around an axis instead of moving in a straight line.
If the images element could rotate it might be able to take digital panoramics :)

Or even better - set up the camera so that it take constructs linear strip images of various
lengths as the camera is moved - you could move the camera along and construct very long
strip iamges. All sorts of very cool images could be made.
