Turn a Flatbed Scanner into a Camera. Building scanning camera from a flatbed scanner. I'm just itching to buy a really good digital camera, but until they become cheap enough for me to just buy one as a toy, I wanted something digital camera like to play with.
I started playing around with my flatbed scanner to see if I could capture images of stuff around it, by holding the scanner in my hand and rotating it as it scanned. This allowed the focusing lens in the scanner to pick up some of the light from the surroundings. One of my first experiments looked like this: My very first attempt at photography with a flatbed scanner It took a bit of tweaking with the colour balance to get the colours to look even this close to real. This looked moderately promising. Camera mechanism My approach basically involves trashing a $100 scanner. Front view of my scanning camera For the lens, I used an obsolete 35mm F/2.8 screw mount SLR camera lens. I mounted it to the CCD by cutting a slot in a block of wood.

The situation is that I have come to a time where there is a lull in enthusiasm for writing but I have lots of enthusiasm for doing stuff. The result of all this is that I have followed up on the Demonstration Quality cheap scanner based improvised digital camera (wow! That's a mouthful!) So, right now what I would like to do is to share a couple of photographs with you. I am happy to say that I have now used the array to make a color photograph and it is shown below. I decided to scan anyway, placing the full 360 degree view within the available space.
However, later on I used the Photoshop program to compress the height of the image without changing its length. Demonstration Quality Scanning Digital Camera. Demonstration Quality Scanning Digital Camera Andrew DavidhazyImaging and Photographic Technology Department School of Photographic Arts and Sciences Rochester Institute of Technology For many years now I have been trying in vain to obtain a sophisticated line-scan digital camera back or a simple linear CCD array camera and although I was close in a couple of instances, things never panned out quite right.
In a technology teaching environment having access to the basic operating systems of devices is very important but destroying sophisticated instruments that I did manage to borrow was out of the question. So, for many years I drew parallels between digital scanning imaging devices and their "photographic" predecessors but could never actually easily demonstrate the connections between them. Well, I have finally achieved my "digital dreams" by purchasing a small Kodak snapshot scanner.
At the time I bought it the scanner cost less than $50 but it did need a computer to hook up to. 1. 2.
