Trends in CMOS and CCD image sensors

Developments in both CCD and CMOS imagers are opening new applications.

For years, CCD and CMOS imager vendors have argued the merits of each particular process technology. However, for machine-vision applications, CCD imagers remain the detector of choice, while CMOS imagers are being used in more specialized applications requiring high speed, low cost, random access, or high dynamic range. Many of the reasons for this lie in the specific design of the pixels and readout electronics associated with each particular device.
