Q: Could you explain the basics of CCD and CMOS technology?
CCD and CMOS technology are fundamentally different; their underlying architecture is different. In a CCD device, the charge is transported across the chip and read at one corner of the array. An analog-to-digital converter turns each pixel’s value into a digital value. In most CMOS devices on the other hand, there are several transistors at each pixel that amplify and move the charge using more traditional wires. The CMOS approach is more flexible because each pixel can be read individually.
