Canon Develops World's Largest CMOS Sensor

The new sensor beside a 35mm Full Frame Sensor


Canon succeeds in developing world’s largest CMOS image sensor, with ultra-high sensitivity


TOKYO, August 31, 2010-Canon Inc. announced today that it has successfully developed the world’s largest*1 CMOS image sensor, with a chip size measuring 202 x 205 mm. Because its expanded size enables greater light-gathering capability, the sensor is capable of capturing images in one one-hundredth the amount of light required by a professional-model digital SLR camera.


At 202 x 205 mm, the newly developed CMOS sensor is among the largest chips that can be produced from a 12-inch (300 mm) wafer, and is approximately 40 times the size of Canon’s largest commercial CMOS sensor.*2


In the past, enlarging the size of the sensor resulted in an increase in the amount of time required between the receiving and transmission of data signals, which posed a challenge to achieving high-speed readout. Canon, however, solved this problem through an innovative circuit design, making possible the realization of a massive video-compatible CMOS sensor. Additionally, by ensuring the cleanest of cleanroom environments during the production process, the sensor minimizes image imperfections and dust.


Because the increased size of the new CMOS sensor allows more light to be gathered, it enables shooting in low-light environments. The sensor makes possible the image capture in one one-hundredth the amount of light required by a 35 mm full-frame CMOS sensor, facilitating the shooting of 60 frame-per-second video with a mere 0.3 lux of illumination.


Potential applications for the new high-sensitivity CMOS sensor include the video recording of stars in the night sky and nocturnal animal behavior.


Through the further development of distinctive CMOS image sensors, Canon will break new ground in the world of new image expression, in the area of still images as well as video.

Do we have a large format capture back here in the makings?
What is truth?

this could be really amazing for applications in telescopes or satellite-based imaging of planet earth... don't think I'd want to lug around a camera body built around that thing

Strange that Canon doesn't give any information on the MP count or on pixel density...  ???

Although no ISO sensitivity is stated, we can make some assumptions and get an idea of where it may be.  They say that it will shoot in 1/100th the light of the 5DII.  If we take that as ISO 6400, the highest standard setting on the 5DII, then 1/100th would be about 6.5 stops faster or somewhere above 409,600.

6400
12,800 (1-stop)
25,600 (2-stops)
51,200 (3-stops)
102,400 (4-stops)
204,800 (5-stops)
409,600 (6-stops)
(this sensor)
819,200 (7-stops)

ok, I know I want bigger sensors with more pixels, but this is INSANE

rolling shutter must be pretty bad on it  :P

That is totally awesome!  Quick, someone grab a Sinar ;)  Or maybe digital IMAX?

Now before someone goes and tells me that there is no way this will ever make it into production...I know...and I don't care.  Canon seems to enjoy design excercises (50 or 120mp sensor anyone?), and I just think that it is cool that they are pushing the limits.  Wow, that is really neat!

Hm, let me make a guess... Should that be 640,000 maybe? (6400 * 100)  ::)

Is this the "*BIG* Anouncement that Vincent Laforet meant?

Whoa, just did the math and realized that is over 8" across!  Forget the 4x5, where did you put the 8x10 view camera :D

You would need a monster lens to supply that sensor with a big enough image circle. Sounds perfect for wide-field telescopes, but I'm curious what other applications. Probably just a technical demonstration with no plans to put it into production.

I find it annoying, though, that they keep perpetuating the myth that larger sensors are more light sensitive, when it's (almost) all in the aperture of the optics. Larger sensors merely samples a larger field of view.

Wow!
But I am almost certain that this sensor will never go into any consumer product. Maybe professional astronomy, medial x-ray sensors and the like, where up to now very expensive CCD sensors are used - although I am not aware of one *that* big.
I wonder what the readout time is like...

Great news! This is a new milestone for Canon. They are leaders in making sensors and not just cameras!  :)

As people always complained that xxxD bodys beeing too tiny for their hands, and that 1000D-body is even smaller, canon decided to make 2000d a camera for people with big hands. that's what this sensor is for. ;-)
