Canon develops high-sensitivity 35 mm full-frame CMOS sensor for video capture
Canon has successfully developed a high-sensitivity 35 mm full-frame CMOS sensor exclusively for video recording. Delivering high-sensitivity, low-noise imaging performance, the new Canon 35 mm CMOS sensor enables the capture of Full HD video even in exceptionally low-light environments. The newly developed Canon CMOS sensor features pixels measuring 19 microns square in size, which is more than 7.5-times the surface area of the pixels on the CMOS sensor incorporated in Canon’s top-of-the-line EOS-1D X and other digital SLR cameras. In addition, the sensor’s pixels and readout circuitry employ new technologies that reduce noise, which tends to increase as pixel size increases.
Thanks to these technologies, the sensor facilitates the shooting of clearly visible video images even in dimly lit environments with as little as 0.03 lux of illumination, or approximately the brightness of a crescent moon—a level of brightness in which it is difficult for the naked eye to perceive objects.
Using a prototype camera employing the newly developed sensor, Canon successfully captured a wide range of test video,4 such as footage recorded in a room illuminated only by the light from burning incense sticks (approximately 0.05–0.01 lux) and video of the Geminid meteor shower.
