Some new canon patents..

Here's a bunch of US patents for your reading enjoyment.

This one I found interesting, this is a stacked sensor patent. Seems canon is marching ahead to it's own drum and working on this as well:

another stacked sensor patent:

this one is kind of interesting. patent for image sensor and mobile telephones.

Enjoy!

Thanks.

I tried keeping up with Canon patents, but with several US patents each week, and several Japanese patents each week, it took too much time.

Its a thankless pursuit, so here is my thanks for doing it.

Approved or published patents are a snapshot into the past, and what was being done around 2-5 years ago. Sometimes, a patent makes it into a product about the same time the patent is published, Canon never tells us, so its a guess. Often, patents are evolutions of previous patents, going back many years. As new processes and technologies become available, new patents to improve on a previous one are submitted.

Keep searching!

The microlens and some other additional related ones were shown here on CR via http://www.northlight-images.co.uk/canon-camera-rumours-and-info/ a while ago (March/Feb)

It is a bit of a pain keeping up with the patents, but I check them most weeks to add to that page ;-)

usually I go through the applications out of curiosity, these are patents - thus the possible overlap. I only went back around 700 approved patents, so I'm surprised it went back that far. the one microlens patent I see on your page is a different patent.

All these patents every week and still Canon couldn't give me a good reason to upgrade two of my 5D mk iii haha! Maybe they are just too busy applying for patents and forgot to make actual products

To save some time of the keyboard warriors, I don't do video.

Linear USM(Nano USM) is also used in 18-135mm USM lens.

if you are stills only there should be a ton of reasons to upgrade from the Mark III - including alot of patents that dealt with a superior sensor in terms of noise and shadow banding not to mention AF improvements.

Quoting myself from the other thread:

Continuous liveview in EVF

• http://pdfpiw.uspto.gov/.piw?PageNum=0&docid=09369633

Okay, based on the abstract and the flowchart this patent seems absurdly trivial - it's basically "keep the EVF live view going for a while even when the user takes their eye off the EVF and something else (image playback, settings) is displayed on the back LCD, so as not to miss photo opportunities due to a pause when switching back to the EVF". A good idea but definitely should fail the obviousness check.

so it does. that's what you get from quickly scanning 700 patents.

Oh, you're definitely not to blame. Thank you for doing the dirty work digging these up!
