Canon has released industry’s largest CMOS image sensor. The new sensor has a chip size measuring 202 x 205 mm. According to Canon the expanded size brings about the capability of greater light gathering, where it can capture images in 1/100th the amount of light required by a professional model digital SLR camera.
The new CMOS sensor is among the largest chips that can be produced from a 12-inch (300 mm) wafer, making it 40 times the size of Canon’s largest commercial CMOS sensor. The new sensor provides the capability of shooting 60 frame-per-second video with an only 0.3 lux of illumination. Potential applications includes video recording of stars and nocturnal animal behavior.
I am sure there are other types of applications that we can think of, requiring only 0.3 lux of illumination. So much for reaching era of miniaturization!!! source
