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 MV
o Each Sensor and Camera Manufacturer has it’s own
definitions
o 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
Module 2
Module 3
Module X
•Sensitivity
•Quantum Efficiency
•Dynamic Range
•Spatial and temporal
noise (DSNU PRNU)
•Over all system gain
•Linearity
•Color
•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
