What is the Difference Between a CCD and CMOS Camera Sensor?

A lot of words have been written and exchanged about the difference between -- and possible advantages or disadvantages of -- CCD (charged-couple device) and CMOS (metal oxide semiconductor + active-pixel sensor) camera sensors. What really is the difference between them?

Production of Leica M9 CCD Sensors Discontinued

Leica no longer has access to the CCD image sensor inside the Leica M9 series of cameras. As a result "defective sensors cannot be replaced" moving forward, and you'll need to upgrade to an M10 or another CMOS-based Leica camera if this happens to you.

Infographic: The Difference Between CMOS and CCD Sensors

Over the past couple of decades, CMOS sensors have come to dominate the digital photography landscape thanks to their increasing quality and falling costs. If you're unfamiliar with the differences between CMOS and CCD sensors, CEI-Europe has created a helpful infographic that compares the two technologies.

These Animations Show How CMOS and CCD Sensors Work and How They Differ

Want to see how CMOS and CCD image sensors work and how they differ from each other? Photographer and animator Raymond Sirí created a couple of simple animations showing the basic idea of how these two sensor technologies go about capturing light, reading it, and storing the information.

The animation above showing CMOS sensor tech was used in a trial against Canon, Sirí says.

Is This the Difference Between CCD and CMOS Camera Sensors? Nope

Virtually all digital still cameras capture light using either a CCD or a CMOS sensor. Most consumers don't know the difference, and -- given the rate at which CMOS sensors are improving -- both sensors perform equally well in most cases (Leica is rumored to be switching over to the CMOS camp with its upcoming M10).

However, that's not what a PC World store in Ireland wants you to believe. The photo above shows an informational placard that was on display recently in one of its stores. The top image shows a scene shot with a CCD sensor, and the bottom image allegedly shows the "same scene" shot with a CMOS sensor. Hmmm...

Europe to Launch Massive Gigapixel Camera into Space

A 268-megapixel sensor might suffice for photographing the stars through a telescope, but apparently a sensor many times more powerful is needed for photographing alien planets from space. The European Space Agency has just finished building the largest camera ever to be used in space: a camera over three feet wide with a gigapixel sensor composed of 106 separate CCD sensors. Just to give you an idea of how powerful the camera is: it will be able to measure the width of a strand of hair from over 600 miles away, and the thumbnail of someone standing on the moon.

Invisible Paintings That Can Only Be Seen by Cameras

Toronto-based artists Brad Blucher and Kyle Clements have an exhibition titled "Take a Picture" which features paintings that are invisible to the human eye but visible to cameras. To do this, they use a frequency of light that is outside the visible spectrum but visible to the CCD and CMOS sensors found in digital cameras.
