Egami blog publishes Olympus Japanese patent application 2014-135535 proposing a 2-layer RGB-IR sensor. The main purpose is to remove the need in IR-cut filter.
Apart from Olympus' approach (described in this patent), does anyone know whether there are any other attempts for CMOS that do not need any IR-Cut filter?
From what I know Fujifilm/Panasonic is working on something similar (but with a different approach via O-CMOS)...
2012 ISSCC paper 22.7 RGBZ sensor - Samsung "Suppression of residual NIR “fogging” of the color pixels is performed by the ISP using the NIR signal collected by the Z pixel as reference. Simulations show that good NIR fog suppression is possible. " Not exactly the same, from a patent perspective, but conceptually similar.
So just like in the DARPA Vertically Integrated Sensor Arrays (VISA) program then?
ReplyDeleteHow novel!
Guy, do you know what you talk about?

Thanks, Eric!
