Advances in CMOS Image Sensors Open Doors to Many Applications
Understanding the key differences between CCD and CMOS image sensor technologies will allow distinguishing advantages and limitations of each type of device and help in selecting the optimal device for a given application. Since the invention of charge-coupled devices (CCDs) in the 1970s, they have dominated the area of scientific and industrial imaging applications. However, in the 1990s monolithic complementary metal-oxide semiconductor (CMOS) arrays emerged as a serious alternative to
