Actually, I now ermember I do have a
'digital'
camera on the
to-be-repaired [ole, and I suspect it's getting on
for 20 years old...
It's a 'Datacopy 300'. Inside there's a linear CCD
(one line of pixels),
probably around 2000 pixels long. It's moved across
the image frame by a
motor and leadscrew, obviously this camera only
works for static
subjects. Inside the body of the unit are half a
dozen PCBs containing
the CCD drive electtronics, motor driver, ADC,
intensity correction (the
output from the ADC is multiplies -- yes an 8*8 full
multiplier chip is
in htere -- with a vulue from an EPROM, one location
for each pixel on
the CCD, to correct for uneven response of the
CCD)., etc
LOL LOL sounds more like a hand scanner matey! LOL
