The goal of this project is to fabricate a medium format digital camera based on a linear photodiode array. The TSL1406RS array will be scanned across a 65 x 48mm frame, upon which images will be projected by a Mamiya 645 80mm f/2.8 C lens. Image processing and control of the camera will be done by a Teensy 3.2.
Scanner cameras are by no means a new thing – they are as old as digital photography itself. By doing a cursory Google search you can find dozens of such projects based on linear CCD arrays torn out of flatbed scanners, etc. These can produce pretty stellar image quality (and color images, to boot) but the fact that they need to be hooked up to a PC remains a limitation in terms of portability. It is much rarer to see a fully “self-contained” scanner camera which requires no such control by a PC.
Featured Adafruit Product!
Adafruit 1.8″ Color TFT Shield w/microSD and Joystick: This lovely little shield is the best way to add a small, colorful and bright display to any project. We took our popular 1.8″ TFT breakout board and remixed it into an Arduino shield complete with microSD card slot and a 5-way joystick navigation switch (with a nice plastic knob)! Since the display uses only 4 pins to communicate and has its own pixel-addressable frame buffer, it can be used easily to add a display & interface without exhausting the memory or pins. (read more)
