Below is another patent for a multi-layer related sensor patent from Canon has come to light. This is the third one that has appeared in the last month or so.
Keith over at Northlight breaks it down in a way that’s easy to understand. “The issue addressed, is light of the ‘wrong’ colour being reflected from one layer into another, which reduces the ability of different layers to respond to photons of only a particular range of colours. This has the potential to greatly improve the colour accuracy and fidelity of such stacked sensor designs.”

- Multilayer sensor drawback of
- G is light, the image quality is degraded and reflected by the surface of the layer between the G and B layer, re-enters the B layer
- Canon patents
- The provision of the dielectric film and the insulating film as an anti-reflection film
- First insulating layer, B layer, a dielectric film, insulating film, dielectric film, G layer, a dielectric film, insulating film, insulating film, dielectric film, the R layer
- By increasing the thickness of the dielectric film, to suppress the multiple reflection
- The dielectric film is between the G layer and B layer, the reflectance with respect to G is lower than B

Asana, Canon, Dropbox, Google, Newegg and SAP Announce Formation of New Cooperative Patent-Licensing Agreement
TOKYO, July 10, 2014—Asana, Canon Inc., Dropbox, Google, Newegg and SAP today announced the formation of the License on Transfer (LOT) Network, a cooperative patent-licensing agreement that will cut down on patent troll litigation and the growing practice of patent privateering.
Patent litigation reached an all-time peak last year, with more than 6,000 lawsuits filed. Most of those suits came from non-practicing entities, also known as patent trolls—companies that don’t have a business outside of licensing and litigating patents.
More than 70 percent of the patents used by trolls come from still-operating companies. Indeed, in a growing trend called privateering, companies are selling patents to trolls that then use those patents to attack other companies. In some cases, those companies arrange to get a cut of revenue generated from the trolls’ suits.
The LOT agreement is a new kind of royalty-free cross-license meant to address these growing systemic problems. Member companies receive a license when the patents are transferred out of the LOT group. That means that companies retain their right to enforce a patent so long as they retain ownership of it. However, as soon as it is sold, a license to the other members becomes effective, protecting them from attacks by the troll to which the patent was sold.
REDMOND, Wash., and TOKYO — July 2, 2014 — Microsoft Corp. and Canon Inc. on Wednesday broadened their strategic alliance with the announcement of a broad patent cross-licensing agreement. With this agreement, Microsoft and Canon gain licenses to each other’s highly valued and growing patent portfolios.
“This collaborative approach with Canon allows us to deliver inventive technologies that benefit consumers around the world,” said Nick Psyhogeos, general manager, associate general counsel, IP Licensing of the Innovation and Intellectual Property Group at Microsoft. “Microsoft believes cooperative licensing is an effective way to accelerate innovation while reducing patent disputes.”
This agreement covers a broad range of products and services each company offers, including certain digital imaging and mobile consumer products. Microsoft and Canon have a long history of collaborating to bring high-quality, cutting-edge products to consumers, including color technology. Contents of the agreement will not be disclosed.
“This agreement is a natural extension of our longstanding relationship with Microsoft and commitment to developing innovative technologies,” said Hideki Sanatake, senior general manager, Corporate Intellectual Property & Legal Headquarters of Canon Inc.

As we get closer to the replacement of the EOS 7D, we’re starting to see some patents that will probably point to some features in the upcoming camera. The recent sensor patent is interesting, as well as this viewfinder patent. We had heard previously about the possibility of a 1.15x magnification viewfinder on the next flagship APS-C camera, which would have been equal to the size of a full frame 100% coverage viewfinder.
This viewfinder is slightly larger than the one on the EOS 7D.
A note about the sensor patent, we have heard that Canon is holding back some sensor patents until the camera is announced to the public, as all patent information is public domain. We’ll see if that turns out to be the case.
