New Pentax Patents - K10D?

Go to last post
We haven't even had the K10D released yet and we have the naysayers already writing it off. Good to see. Keep it up!

All this sounds very interesting, I can't wait till Pentax announce.

I just hope none of this is either pure speculation or vapourware;
patents have a habit of sitting there and not becoming reality.

I have seen some of the technical data of this camera but it is under embargo and I cannot disclose detail. I have no idea, however, what patents Pentax have used in the camera and I'm no expert on sensors for digital cameras.
 
Not that I want a live-preview system, and I don't think many people do, but this patent about noise developed by CCD heat levels on longer exposures is a key problem in getting live video feeds off CCD sensors of APS-C size and above. Now this is obviously a problem in endoscopes which feed video to a monitor for analysis. I think this makes more sense, although I see no reason why it couldn't eventually make it into a DSLR either as part of a live view system or non-software noise reduction for long exposures.

Errr... you replied to my post, but I said nothing about the K10D?

I happen to think it'll be an excellent camera, but I have strong doubts about some of the unsubstantiated 'facts' people are spreading here.

For the patent -- if it means little to no noise in long exposures, without the time-consuming dark frame, then it could be a big bonus for many situations (fireworks and such).

Sorry, I replied to the wrong post.

There is quite a bit of rumour mongring going on, for sure.

Am I the only that noticed that this patent was filed in December of 2000? Since that time many of thes patents filed are related to endoscopy systems.

I know Pentax is slow in development for their DSLR's but 6 years from patent filing to production in todays fast paced technology environment...I'm not gonna make more of it than it actually states.
 
Good to see there working on it but full frame transfer CCD's have been around awhile. See this from 2000.

Anyone remember Kodak??? As a side note it used the TWAIN standard and not RAW, which in my opinion I had wish they stuck with. No DNG debates and would leave Adobe pretty much out of the loop... Maybe our poor Kodak was too far ahead of it's time. Used almost every portable storage device short of a ful fledged hard drive. Sweet. Never used one but is this the moire riddled one?

Actually, it has a date from an application filed in Japan in 1999.

I wouldn't worry too much about the reference to endoscopes. This was the most likely use then, but the patent is not limited to that. If the technilogy may be used in any CCD they may use it for cameras as well and in 1999 maybe they didn't want to publish the fact that they were developing a dslr. Later patents refer to both endoscopes and cameras.

And by the way: 7 years from first invention to production is not much, even in this race. Ideas are patented, and then their improvements, all the way to production, and Pentax has filed a lot of applications recently.

We do not know if Pentax will use this specific patent, but we know that they have been working on noise issues in CCD sensors, and from later applications we know that they have continued doing so. At least it does give us some indication of what we may expect.

Use the advanced search option of espacenet and search for Sato Koichi as inventor (he seems tyo be the key inventor) and Pentax as applicant."

You will pull up the recent patents in chronological order.

If you leave the inventor field empty, you will pull up 100's of patents filed by Pentax in the last few months alone, many are related to photographic technology. They even patent their flexible packaging!

Think there all serial (line by line transfer) not full frame (all data at once), at least how I understand it. Nikon 200 uses 2 serial pipes to unload the data.
I could be wrong though...

Hi Dave!

"In such a case, in the CCD of the full frame transfer type, the
unwanted electric charges generated in a light receiving element
flow into light adjacent light receiving, so that a smear occurs,
which may cause the quality of an image signal to deteriorate."
Sounds like noise reduction system to me.

Actually, this section sounds more like prevention of highlight "bleeding" to me. Also known as Blooming http://www.dpreview.com/learn/?/Glossary/Digital_Imaging/Blooming_01.htm
Right? Wrong?

Try again with another inventor, Kato Tetsuaki, and you will find some other interesting stuff...

we're not getting out expections up too high...

Expectations are already too high! I can imagine the heavy traffic after the coming pentax-announcement about 'missed opportunities', 'going to switch brands', 'how could they not implement this/that function', 'still not competetive with ..' etcetera ;-)

Your probably right.

By reading at this post to PDML, written by the gentleman who has contact with Pentax Norway and couldn't talk because of the embargo, I think there are some visible hints. Please note the capitalized words in this post below：

----------- Quote Begins -----------

Re: Testing the K100D and some more K10D hype

Pentax Norway showed me a slide presentation which had "CONFIDENTIAL" spelled out in red letters on all the pages, so my lips are Sealed.

Not entirely sure what you mean about the "big part", there were
several bits of info to Mount my tension.

With all the posts over the subject I really wish I could Mute some of
the Noise on the list, but the press release to be timed before
Photokina will unveil the secrets, I'm sure.

Jostein

------------ Quote ends -------------

My own intepretation of the capitalized words contained in this text:

Sealed: weather sealing?

Mount: new lens mount, KAF3 maybe?

Mute Noise: noise reduction technology related to the new patent and/or new ASIC?

What do you think?
