Abstract
This document describes the development of a prototype of an interface between
a CMOS camera and puter. This interface allows a user to get images
from the camera, to change some of the properties of the camera as brightness,
luminance, etc. In addition some image process is implemented allowing the
camera to track white objects and follow them with a servomotor. The interface
was implemented using the Atmel AVR ATmega16 microcontroller.
This document is a final report of the course Digital Project of LTH (Lunds
Tekniska hogskola) Sweden. This report and information related to this project
