Patent: Large Back Illuminated Sensor

[Canon Rumors]

Share

New Sensor Patent Canon has published a back illuminated sensor patent for APS-C and Full Frame sensors. Back Illuminated Sensors allow for a more effective use of pixel area.

Patent Publication No. 2012-15275

• 2012.1.19 Release Date
• Filing date 2010.6.30

Back-illuminated imaging device

• The two bonded substrates photoelectric conversion unit and the peripheral circuit manufacturing to
• Photoelectric conversion unit and the peripheral circuit microprocessor which is connected by bump
• The incident light is changed and the current strong influence to adjacent pixels in the peripheral circuit, and noise (similar to a smear phenomenon).

Canon’s patented

• And a peripheral circuit connected to a DC power supply photoelectric conversion unit
• Resistance is lowered, reducing the voltage drop

at what time point the patents are published? once when the technology ready on paper or once is is physically ready? If the last one is correct, then, assuming canon 5dmk3 comes out in march, would it be stupid to expect that it has that new back-illuminated sensor?

[Peerke]

Well, there go the sales on the 1dx . Except for the pro's of course to shoot the olympics and the European championship soccer.

If Canon would bring out the 5d3 without this sensor, that would give us luckely the chance of ranting over here why the 5d3 doesn't have a back illuminated sensor. Yes, please  .

 I always though patents where applied for once you had a working prototype? This increases the chance it'll get granted.

Patents are published 18 months after the priority date of the patent application.  Companies generally time their patent applications carefully - too early and they risk having their invention/technology disclosed well before they have a product ready (assuming a product is the intention - many times, it isn't), too late and they risk being beaten to the punch with 'prior art' (filing the application is the cut-off date for prior art being prior).

Yep, just like everyone stopped buying 1D IV's after Canon announced their 120 MP APS-H sensor...

Is it written anywhere that the 1DX isn't using this technology?

And what if it were?

Of course

As someone that has been responsible for patent applications being made and approved by the USPTO, I can tell you that no, a working prototype is not required.

Is it written anywhere that the 1DX isn't using this technology?

Nor is it written that the 1D X doesn't use clairvoyance technology to pre-focus exactly where the action will take place.  If it had a BSI sensor, Canon's marketing department would make sure everyone from the president of the USA to the rats in the sewers of Calcutta knew about it...

Hum... strange. As far as I understood BIS it shouldn't be a big anhancement when applied to a large area sensor such as APS-C or even FF...

Does Canon trumpet any particular patents when the release a new lens that is covered by them?

Or does any other camera manufacturer?

Given all of the patents regarding specific technologies in cameras, do any of them get trumpeted?

What do you think is more important for marketing: BSI or how many MP?

What do you think the average Joe on the street that walks into a camera store cares about?

You fools! Can't you see that this means that the 1D XXX is due for release this year 

[Peerke]

You fools! Can't you see that this means that the 1D XXX is due for release this year 

Yes we can 

[NotABunny]

The 1DX announcement said that its sensor is using a super-efficient diode, so I gather if it had BSI, they would have said so.
