One for All, and All for One – A Flexible Approach to CMOS Line Scan Design
Mar 19, 2013Our internal projects typically have names that are more “fun” than the part numbers that end up in our datasheets. I’ve been involved in projects with names ranging from star constellations and wine varieties to superheroes! A while back, I … Continue reading
Spectral Cognisance 4 – Is Lux more than Luxury?
Feb 15, 2013Coming from a Machine Vision World, “Lux” and Human Vision have been a mystery to me for a long time. Thankfully, we have had some customers in the application of human vision and I’ve been able to remedy this situation. … Continue reading
Happy Holidays.
Dec 19, 2012So, we’re at the end of the year and have arrived at our final post for 2012. I’m not promising brilliance, mostly just a really quick review and the opportunity to thank our readers and contributors for their continued support … Continue reading
Spectral Cognisance 3 – When Black turns Red
Nov 23, 2012We have established that emission and absorption spectra are quite important in image sensing. Why is this so?
Spectral Cognisance 2 – How White are your Whites?
Sep 12, 2012In my first post in this series I started at the beginning of this story. We have seen that the optical path and the sensor itself modulate the effective spectrum that is available to generate signal for an image sensor. Filtering, … Continue reading
Are All CCDs Dinosaurs?
Jul 3, 2012My youngest boy, who is crazy about dinosaurs, once asked me if all dinosaurs perished right after the great meteor impact. “No,” I said, “some survived long after.” In 1993, Eric Fossum delivered the provocative but seminal presentation “Active Pixel … Continue reading
Outsourcing or In-housing – A Source for Debate in the Modern Age of Imaging
Jun 26, 2012The topic of outsourcing is often a subject for debate by politicians, managers, engineers, business owners and even human rights groups. Depending on the product, it can be a significant cost benefit to outsource certain aspects of the production process. … Continue reading
All That is Old is New Again
Jun 5, 2012Most would point to the middle part of the last century as the birth of electronic imaging. RCA, Philips, EMI and others introduced several generations of tube image sensors with names like Orthocon, Plumbicon, and Vidicon. In all cases the … Continue reading

A simple way to determine Charge Conversion Efficiency for a CMOS sensor
Feb 21, 2012An important characteristic of an image sensor is its ability to convert electrons into output signal. Most CMOS image sensors include on-chip ADCs which convert the analog signal coming from the pixel into digital numbers. The CCE (Charge Conversion Efficiency) … Continue reading
Sensor Quantum Efficiency, Social Media and Matthias.
Jan 24, 2012Hello, My name is Matthias. Like Cher, I’ve decided not to publish with my full name, for a few reasons, but mostly as a result of recent conversations with my wife about spam (not the meat) and security. I admit, … Continue reading
