Clear definitions for a
clear VISION
EMVA 1288 Standard for Measurement and Presentation of Specifications for Machine Vision Sensors and Cameras
EMVA 1288 Workshop Vision 2006M. Wäny www.awaiba.com
Workshop Program
o Why we need 1288 Prof. Bernd Jähne, University Heidelberg
o Organization of 1288 Working group and standard Martin Wäny, AWAIBA
o Basic Information Dr. Emil Ott PCO
o Module 1: Sensitivity, temporal and spatial noise, Dynamic range… Dr. Fritz Dirks BASLER
o Module 2: Linearity and linearity error Dr. Kari Siren TVI

Motivation
o Existing Standards for cameras are not suitable for MVo Each Sensor and Camera Manufacturer has it’s own
definitionso The Customer is left guessing with datasheets

The 1288 Standardization Working group
o Founded in February 2004
o Driven by the industry
o User oriented. „Make the MV Engineers lives easier“
o Open Working Group

Approach
o Modular standard framework New modules are to complete the standard rather than to
replace previous versions
Module 1•Sensitivity•Quantum Efficiency•Dynamic Range•Spatial and temporal noise (DSNU PRNU)•Over all system gain
Module 2•Linearity
Module 3•Color
Module X•More to follow
The modular approach protects investment in measurement equipment, processes and education

Current Status & Roadmap
o First Module Released in Sep 2005 (Sensitivity, SNR)
o Second module (linearity) in Preliminary release. Official release planned in Q1 2007
o Vision 2006 show’s many 1288 compliantly characterized products
o Preliminary release of third and fourth module (Color & Defects/Artifacts) planned for Q1 2007
