Patent: Large Back Illuminated Sensor
« on: January 23, 2012, 12:03:54 PM »
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?

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  ;D.

 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?

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... :o

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

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.

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?

actually Canon does trumpet newly patented lens ideas on lenses all the time.  remember the big deal they made over Hybrid Image Stabilization (H-IS) on the then-new 100 L Macro.  and it's good business to play up all the new technology in whatever item you're selling, it's been demonstrated that consumers are (wrongly) easily impressed by the quantity, not quality, of features and specifications.  between two identical items put up for sale, consumers will more often choose the one that has a longer specification list posted.

I'm fairly sure if BSI on large sensors were being employed by Canon on the 1DX, they would be talking about it (especially what with all the white papers they've posted so far).  I don't think this will stop people from purchasing the 1DX any more than the future 5DIII has stopped people from purchasing the real, current 5DII.

Our Friends at Sony are keeping busy too...

from the looks of it, seems like it should enable higher SN rations with more of the Die soaking up photons. Will Sony be able to use this in APS-C / FF soon? Our Nikonian friends would also be excited.

Great, in 10 years will be overwhelmed with way overdone HDR movies in theaters. Probably directed by Michael Bay...
