Machine vision - old schoolOld School Technology

Near Paper Silicon  



Light travels to camera from afar

Better light collection

Multiple units (light and camera)

One unit, less vibration

Light distorted sideways (wide angle)

Uniform Illumination

Higher volume

Smaller volume, easy to ship, install and maintain


High cost: Using Machine Vision industry specific subsystems

Low cost: integrated processing H//W, use of common CIS dies


Separate modules lowers MTBF

One unit: more robust, better MTBF

Requires additional metal to install on press

Compact, seamlessly integrated

Skilled engineers to install and maintain

Repair by replace
