InVisage Quantum Film

A couple months ago we wrote about an innovative sensor technology from InVisage called Quantum Film. You can read our earlier article for specifics on how the technology works, but the abbreviated version is that instead of using silicon as the light sensitive medium in its sensors, InVisage Quantum Film uses a layer of nano-scale crystals that respond to specific frequencies of light. The primary benefits of the technology are expanded dynamic range (compared to silicon-based sensors) and global shutter, which eliminates the jello effect often seen in CMOS sensor designs.

In a private meeting with InVisage we finally had a chance to see these sensors in action, and we’re excited. To show off dynamic range InVisage set up a mini studio scene with color charts in high contrast bright and dark areas (see photo above). Three phones - an iPhone, an 'popular Android phone,' and an unreleased phone with an InVisage sensor - were lined up for comparison. To our eye the InVisage sensor definitely captured more dynamic range, appearing a bit similar to Log video footage. We were also able to see global shutter in action in a side-by-side comparison to an iPhone. In this video, you can see the difference global shutter makes when capturing certain types of motion such as a vibrating guitar string.

The good news is that you won’t have to wait long to get your hands on this technology: InVisigen tells us the first phones with their sensors are expected to ship in Q1.
