What is it?
Intelligent camera- as sharp seeing as a lynx
Main target is not to generate pictures
The goal is to analyse the image
The mvBlueLYNX series include area and line scan cameras with different resolutions

System Software
Why Embedded Linux?
Standard operating systemModular and configurable Kernel.Excellent network features.Proven long-term reliability.Open source
• no license costs, • no proprietary "standards".
• "Real-Time" Linux available. • Large, easily-available knowledge
base.

Programming
Similarly as with a PC system with frame grabber
With library for the camera and acquisition control
Differences: Linux instead of WindowsProgram is executed on mvBlueLYNX and not on the PC

Programming
Setup network on a server
GNU C/C++ Cross-Compiler for Linux or Windows
Development with well-known IDE (i.e. MS-VisualStudio)
Telnet Console over network
Access the server from mvBlueLYNX
Start program from server
When ready: Copy into Flash
Setup Autostart
