Canon continues to work on organic sensors

Organic sensors are probably the "next big thing" to hit semiconductor sensors.  Basically instead of using a photodiode to collect light, they use an organic compound to convert light to energy.

Since this can be applied as a thin film (or films) the sensor itself can be made very efficient, surpassing today's best sensors as far as performance.  Panasonic and Fuji in a joint venture are also looking at organic sensors.

From all of Canon's organic sensor patents, this is the first one that actually shows anything that looks like an image sensor in the diagrams, maybe a sign that they are getting further ahead in the process.

This patent deals with a high conversion efficiency and a wide absorbion wavelenght (necessary to convert the full spectrum of light).

Wether or not this will make it into an actual sensor is anyone's guess - these could be years and years away from an actual camera.  However it shows what Canon is thinking about for the future of image sensors.

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!
