GameBoy Camer Interface

Description

Interface to gameboy camera, could capture images and send them to the PC....was made a while ago and did not save any of the pictures taken and I'm probably not going to get it working again. The pics were ok, although it was quite difficult to get the exposure and contrast correct.

Simple image processing was also implemented, this was based around image subtraction then a scan to find areas of high values...this achieved movement detection in a 8x8 grid in the camers FOV.

Specification

Main Features

MCU: AVR Meag161

Memory: 64KB SDRAM

Camera:GB cam

Takes 128x128 pictures
Approx 15 frames/sec
...5 when image processing

How it works

The camera uses the M64282FP 'Artificial Retina'. It is quite easy to interface to...there are a few control lines and an analogue data line on which the image is sent. I had to use an external a high-speed A/D converter (AD7819YN) as the AVRs internal A/D is much too slow. A quick tip for if you are planning to use the GB cam is to clock out the image into a buffer as fast as you can first as I think the 'pixel capactiors' drain quite quickly.
