After the 120 MP APS-H-size CMOS sensor, Canon announced today that they developed the largest CMOS sensor sized at 202 x 205 mm or 7.95 x 8.07 in.
Canon Succeeds in Developing World's Largest CMOS Image Sensor, With Ultra-High Sensitivity
LAKE SUCCESS, N.Y., 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. The sensor is capable of capturing images in one one-hundredth the amount of light required by a professional-model digital SLR camera due to its expanded size enabling greater light-gathering capabilities. Potential applications for the new high-sensitivity CMOS sensor include the video recording of stars in the night sky and nocturnal animal behavior.
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 the realization of a massive video-compatible CMOS sensor possible. Additionally, by ensuring the cleanest of cleanroom environments during the production process, the sensor minimizes image imperfections and dust.
The increased size of the new CMOS sensor allows more light to be gathered thus enabling 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.
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.
