Film To Digital Chip Direct Contact Sampling?

Post by S8 Booster »

for Carl and other transfer buffs:

with todays tremendous development in digital chip technology it should be within reasonable reach to put say, a super-chip of about 8/s mm or 16mm right in the gate of 8/s 16mm projectors and project the image right on with the highest resolution and lowest loss in the optical path? simplifying the capture/processing software too?
get rid of all glass in between?
let the film plane with the chip?

ok, some modofying of projector/drive/gate budd neverDless.....

shoot.....film-....all summer...

The problem is that the imaging chip has a thin layer of glass that will always separate the film from the sensor array. The glass is thicker than film, itself, in most cases, and would be like trying to contact print film through the base, which ends up much softer than copying the film with a lens. Ironically, what you are suggesting would only be possible if a lens was used to project focused light through the film to carry the image past the glass that separated the film from the sensor. At that point you would end up with image spread due to the distance between the film and the sensor so it would no longer be 1:1. Focusing the projected image onto the sensor is easier and more practical.

In addition to the good points Roger makes, you would never keep the sensor clean.
Off all the things I've lost, I miss my mind the most.

But then you'd have to wipe in phase with the scan and movement of the film. Very complicated.

I thought about that problem a few years ago. What if one could use three LASERs (R, G, B) from a distance of a meter or so to shine the image onto the sensor (my thought at the time)? Of course, by then, you might as well be using a flying spot scanner and do away with the CCD all together.
I may sound stupid, but I hide it well.

should be fairly easy to overcome the dust issue by using a beam splitter (pass through only) from an high end S8 cam (or more suitable equivalent) between the chip and a linear light source or laser as light source.

dust removal device (both film and glass frame by frame) and /or super surface treatment of the beam splitter/verso should be fairly easy by today´s technology. cost not considered.
easy digital frame by frame advance by digital technology, lift film off plane, clean frame plus gate in one operation and put film back and re-align to the gate in one smooth operation.

one of NokiaÅ› latest mobile phones is chipped with 41 mpix or so...not all of it used but for interpolating an better image.

5, 8, 41 mpix image sencors, 41 in new Nokia.
