CCDs (Charged-Couple Device) tend to be used in cameras that focus on high-quality images with lots of pixels and excellent light sensitivity. CMOS (complementary metal-oxide semiconductor) sensors traditionally have lower quality, lower resolution and lower sensitivity. CMOS sensors are just now improving to the point where they reach near parity with CCD devices in some applications. CMOS cameras are usually less expensive and most manufacturers are using CMOS chips. CMOS sensors outperform CCD in many respects, particularly as it applies to most surgical imaging, microscopy. In imaging tasks where CMOS is used in 3-chip cameras, one can fully realize the improved resolution, sensitivity, and color reproducibility which is unmatched by single-chip cameras. For typical full motion video imaging, CMOS technology continues to advance and will meet the requirements of emerging formats like 4K and advanced image processing functions which take advantage of the digital nature of CMOS. A strong advantage for CMOS technology is that it provides digital output and can be controlled at the pixel level in ways that are not possible with CCDs that provide analog output. For most applications CMOS provides the better choice
