CMOS Sensor vs CCD Sensor - Which one is better for Digital Cameras

Todays Digital cameras are extremely common and prices have gone down because of the introduction of CMOS sensors, which are cheaper to produce then CCD Sensors.

CCD stand for (charge-coupled device) and CMOS stand for (complimentary metal-oxide semiconductor) both work in the same way and convert light into electrons. Once the Sensor accumulates enough charge, it is transported and read an converted from analog to digital from pixel to digital value which we see on our LCD screens and outputed to print.

• CCD are said to creat higher quality and cleaner files than CMOS
• CMOS is power efficient compared to CCD Sensors.
• CMOS are cheaper to produce thats why most cameras use CMOS
• CCD technology is older and been optimized for better quality.
• CMOS is gaining ground with the CCD technology and soon will outdo CCD
• CCD has advantage in Dynamic Range and Noise over the CMOS
• CMOS has the advantage over CCDs because all camera functions can be placed on the image sensor.
• CMOS has natural blooming immunity (Antiblooming, the ability to gracefully drain localized overexposure
  without compromising the rest of the image in the sensor) CCD requires engineering antiblooming also known as simple as over exposure
• Both image chip types are equally reliable in most consumer and industrial applications.
• Both types of sensor accomplish the same task of capturing light and converting it into electrical signals.
• CMOS image sensors are designed for a large, consumer or near-consumer application.
• CCD image sensors, on the other hand, are more general purpose.

Some CCD Cameras : Nikon D60, Fujifilm FinePix S5 Pro, Nikon D80, Nikon D40X, Canon PowerShot G9, Canon PowerShot Pro1, Ricoh GR Digital

Some CMOS Cameras: Nikon D2Xs, Nikon D3, Nikon D300, Canon EOS 450D, Canon EOS-1D Mark III, Canon EOS-1Ds Mark III, Canon EOS 5D, Pentax K20D, Samsung GX-20, Sigma SD14

If you check the sensor use in the above list of cameras that use ccd or cmos, it is safe to infer that CMOS sensors are used on the high-end cameras for specific uses and for varied highly customized camera features and speed. Will the CCD technology which came earlier and is already mass produced is used on prosumer cameras with a wider market base. (value for money?)

In the end, each camera gives its own distinct character, color, and feel. Choose one that best suits your shooting style and imagery style. It is hard to say which one is better since both technologies are evolving and the new cameras keep getting better and better.

In the end, it will always be the image, content and the story it tells… whatever camera you use.. Happy Shooting!

Wait there’s more! Take a peek and see the Beauty of the Philippines!
