![]() ![]() Due to their physical architecture, CMOS sensors lacked the sensitivity of CCDs. Source: ĬMOS sensors are generally less expensive to manufacture and rapidly found popularity in consumer cameras, cell phones and security cameras. In a CMOS sensor, this process happens within the pixel microelectronics. CCD sensors read off the electrons row by row, and then the electrons are converted to voltage (analog to digital). ![]() ![]() Photons are converted to electrons in the pixel. Other companies still manufacture CCDs, but attention has definitely shifted towards CMOS. One last note about CCDs is that Sony discontinued production of CCDs in 2017, focusing their development efforts on CMOS technologies. ICCDs are still in use today and are suitable for very low light applications such as fluorescence and luminescence. For even greater sensitivity, CCDs could be intensified (called ICCDs) to further amplify the signal. They offered better sensitivity and generated less noise in the signal (think of it as static) than their CMOS counterparts – this was all the result of the sensor architecture and how the data was transferred. CCDs (Charge-Coupled Device) were the norm up until a little more than a decade ago. The discussion of whether to choose a camera with a CCD or CMOS sensor is practically moot at this point.
