One for All, and All for One – A Flexible Approach to CMOS Line Scan Design

Mar 19, 2013

Our 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, 2013

Coming 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

Spectral Cognisance 2 – How White are your Whites?

Sep 12, 2012

In 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, 2012

My 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

All That is Old is New Again

Jun 5, 2012

Most 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, 2012

An 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
