A Smart Camera Is An all-in-one device used to locate, identify, and

inspect objects

A vision sensor that outputs inspectionresults, not images

The fusion of an automation controller with a

camera sensor

High-performance processor

PowerPC, DSP, or X86 Built-in I/O

Real-time operating system

Programmed or configured remotely

Industrial camera

CCD or CMOS Many sensorspeeds

Many sensorresolutions

Standard lens mount
