Canon Lost Trial In Patent Infringement Cause (sensor Technology)

Company Intellectual Ventures accused Canon of patent infringement. Canon lost. Two image sensor patents are concerned: US6,221,686 “Method of making a semiconductor image sensor” and US6,023,081 “Semiconductor image sensor.”

Delaware Intellectual Property Litigation published a document with the motivations (see pages 11-19).

By Memorandum Opinion entered by The Honorable Sue L. Robinson in Intellectual Ventures I, LLC, et al. v. Canon Inc., et al., Civil Action No. 11-792-SLR (D.Del., May 18, 2015), the Court granted plaintiff’s alternative motion for a new trial regarding infringement of U.S. Patent Numbers 6,121,960 (“the ‘960 patent”) and 5,754,348 (“the ‘348 patent”) after concluding that defense counsel in his closing argument improperly played the role of expert witness by inferring from factual testimony that the accused devices did not meet the claim limitations arguments.  The court found such argument to be contrary to a pre-trial agreement that defendant would not present any evidence of non-infringement, including evidence of a lack of a subjective intent to infringe, particularly given that the Court previously barred certain testimony from plaintiff’s witnesses on the topic during the trial.

How to get the most out of Canon EOS 5DS and EOS 5DS R files (Canon DLC)

eos 5ds

The Canon Digital Learning Center posted an article about how to work and get the most out of the files produced by the 50MP EOS 5DS and EOS 5DS R cameras.

The 50.3 million actual pixels in an EOS 5DS/5DS R high-resolution file make it easy to spot the tiniest of errors. This may not matter much to the sports photographer using an EOS 5DS for a great magazine cover shot or a wedding shooter shooting group photos at a wedding. But to the super critical landscape photographer, who is expecting every blade of grass to be visible in that scenic shot if it’s printed with a 44-inch wide-format printer, or the studio shooter who wants every last bit of detail in that product shot, there are ways to get those results.

The technology behind the Canon EOS 5DS and EOS 5DS R – Interview with developers

5ds

Canon Asia posted an interview with the deveolpment team behind the Canon EOS 5Ds and EOS 5Ds R. An excerpt:

Question:What was the reason for not changing the AF sensor? Was it because the performance of the system on the EOS 5D Mark III was good enough?

Answer: Yes, you are right. The EOS 5D Mark III and the EOS 5DS series share exactly the same principles of forming an image on the focal plane. It can handle any number of pixels as long as the level of accuracy is maintained. The existing AF sensor is perfectly fine since it has a sufficiently high level of detection performance.

[…]

Question: What changes were made to the existing firmware following the upgrade of the pixel count to about 50 megapixels?

Answer: The huge amount of data has a significant impact on the firmware. In order to ensure speedy and smooth data processing under such conditions, advanced and complex processes are needed, such as parallel processing while switching between the memory spaces. As there is limited space in the built-in memory of the camera, it is important to consider how this space can be utilised most effectively.
