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?

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...  ???



Jon Gilchrist:
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.
