The Evolution of Camera Interfacing
The early days, practical but still
just a collection of ill-matched
components!
Better and more integrated, butstill not optimised for ease of use.
A modern integrated system with
power, speed and flexibility

Software Interfacing
Consumer standards exist such as Direct Show and Twain
Machine Vision needs device control and reliability
Develop using an interface library the is GenCam Compliant
Camera and interface providers will supply compliant drivers
Choose a Hardware independent SDK
Supporting non GenCam compliant interfaces
Look for robust image handling and error reporting built in
