Image Sensors Used to Stably Determine Marking Failures of Workpieces on Rapidly Conveyed Lines

Case Number 237

last update: April 18, 2011

This Image Sensor has improved pattern matching. Stable detection of markings is performed even when detecting two dates, such as the manufacturing date and the use-by date on rapidly moving workpieces.

Know-How

The unique image processing circuits support high-speed lines performs matching with models dividing images into smaller parts. Subtle differences that cannot be determined by conventional pattern matching are detected as large numerical values.

Benefit / Efficiency

A single Image Sensor is used to inspect markings of two dates.
