Patent: Noise & Aliasing Reduction for Small Pixels
« on: January 20, 2013, 10:21:30 AM »

A patent for APS-C?

Canon has filed a patent to reduce the noise and aliasing in small pixels.


This sort of patent could benefit higher megapixel APS-C cameras, like the EOS 7D Mark II.

Promising. So, how many megapixels will it be. I guess they start conservative with maybe 20. Really hope that 6400 will be usable

If the 7d2 is gonna be announced soon, i guess this is aimed at the high megapickle full frame?

I think the chance that this patent will be applied in the 7DII is negligible, unless the 7DII will be released in 2016 or thereabouts. I'm not sure how much time usually is between filing for patents, getting them granted and using them in products, but I'm assuming it's years rather than months.

If this actually applies to the 7D Mark II, then here comes the super-extended wait!

as you can read the patent was filed 2011 and granted in 2013.
I read the CR post which only told me Canon had filed for a patent. Not a news post, I guess...

The public doesn't find out about patents when they're filed, we find out when they are published - 18 months after they are filed.

A patent application requires reduction to practice.  The implementation presented need not yet be commercially viable or readily manufacturable, but must exist at the time of application.  So a 2011 prototype could form the basis for a product in 2013.

This patent won't frighten the competition as both Nikon and even Pentax are well ahead and already have camera sensors with no anti - aliasing filters and they apparently work.

While Canon makes the finest top of the range lenses I can't help thinking they are falling behind with their sensor technology.

Don't expect much from the 7D II somehow - except delays - perhaps even the same old sensor. Well you can't have everything!

Not that Canon hasn't done some unfathomably stupid things, but I can't see the 7D's sensor in a 7DII.  The 7D is all that and a bag of chips...except for the high ISO noise.

I am not sure if I understood the post properly but there is no info what kind of patent is this. It could be a kind of digital post processing algorithm so It does't have to influence raw and sensor quality but jogs and noise reduction only from a digital side? Is that possible?

Rubbish ... The 5DIII produces no moire or aliasing in video, whereas the D800 is about the same as the 5DII.  Nikon is behind on this.

...except for the high ISO noise.

And  no support for the new flash system, even with the big firmware update. They really like to leave out those small handy details.

I was actually referring to the D800e.

It has less noise per sensor area than the 5D2.
It can be prone to vertical gain banding and the usual low ISO offset bandings.
