This is an Imager Process Review Report on the Canon EOS-1DX 18.1 Mp CMOS Image Sensor. The Canon EOS- 1DX features a full-frame 18.1 Megapixel CMOS sensor that is designed and fabricated by Canon. The camera features dual DIGIC 5+ Image Processors that work with the sensor to deliver high quality image capture at up to 12 fps (14 fps in Super High Speed Mode) and a powerful ISO range of 100 - 51200 (up to 204800 in H2 mode) provides sharp, low-noise images even in the dimmest low-light conditions. This Imager Process Review details the technology used to fabricate the CMOS image sensor.
