Olympus Proposes 2-Layer RGB-IR Sensor

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.

  1. So just like in the DARPA Vertically Integrated Sensor Arrays (VISA) program then?

    How novel!

    1. Guy, do you know what you talk about?

  2. 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)...

    1. 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.

  3. That concept is much similar to VIPS technology.
