In the early 80's Micron Technology (Idaho, USA) made chips specially
designed for this, I suspect they still do. The chips come with a
glass panel expoxied over the actual transistor panel in the chip.
I was able to mount one on the focal plane of a hacked-up 35MM camera
which was mounted in a frame which moved over a page. Primative
optical character recognition was the project.
If I remember the resolution issues correctly I doubt you would be
able to use this method to take "regular" pictures but it might work.
