Canon continues to look at organic sensors

This patent application deals with using organic compounds to increase dynamic range and sensitivity of a CMOS sensor.

This patent application deals with the thermal noise at the time of reset, and when that is improves has the effect of improving dynamic range by increasing the efficiency of conversion.

Organic sensors could very well be the "next big thing" to hit ILC's as most our cameras have entered into diminishing returns for improvements.

If you look at the picture shown. The organic compounds (layers 5-7) are sitting "above" the normal layers of a CMOS sensor.  The signal collection happens underneath.  The sensor then has nearly a 100% surface area to collect light, where current sensor designs are less than that, because of circuits or isolation between photodiodes.

Canon continues to work with organic components, and improving the efficiency of the photoelectric conversion.

When we will see these patents hit a sensor or a camera near you is anyone's guess.   We also know that Panasonic and Fuji are seriously working on this technology and may have a step ahead of Canon; as they have produced at least working samples of organic sensors a while back.

How to view Japan Patent applications.

Unfortunately, there's no direct way of linking to the patent application (sad!) however, this is the easiest process to view a japan patent or application.

  1. Go to the Japan Patent Office search page.
  2. If it's a patent application (they are usually in the format of Year-Number ie: 2017-011300) then type the patent application number into the second field down from the top where it says publication of patent application. 
  3. Click on search.
  4. Then click on the patent application number link, and there's the patent application!
