<p><strong>A patent for APS-C?

</strong>Canon has filed a patent to reduce the noise and aliasing in small pixels.</p>
<p>This sort of patent could benefit higher megapixel APS-C cameras, like the EOS 7D Mark II.</p>

Re: Patent: Noise & Aliasing Reduction for Small Pixels

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.

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.

Re: Patent: Noise & Aliasing Reduction for Small Pixels

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.

Re: Patent: Noise & Aliasing Reduction for Small Pixels

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.

Re: Patent: Noise & Aliasing Reduction for Small Pixels

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.

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.

D800E which has more moire and aliasing than D800? :D Excellent for stills... Bad for movies.

To bad it also has a trademark lack of detail. And the effective resolution isn't even 1080 vertical.

Like every other camera ever built, the 5DIII is not perfect. But it is the best all-round "affordable" media camera available. It has no glaring weaknesses, can be used for every type of photography including sports, and it has many video friendly features like audio level during record as well as for moire-free video that is good enough for broadcast and the big screen. Not bad for $3000.

When your production skills outgrow the 5DIII, you should be looking at a C300, C500, or Sony FS700, because there isn't anything better in it's price range. ... oh ...and it shoots great stills as well.

and low iso noise...

oh and mid iso noise

Re: Patent: Noise & Aliasing Reduction for Small Pixels

i have looked at the patent and as i understand (*) it this is to reduce banding or streaking.

im not sure if this has something to do with the patterns we see in shadow areas when they are pushed... maybe just wishfull thinking.

(*) the translation from japanese into english is bad and my english is bad too. ;)
