Foveon: The Clever Image Sensor That Has Failed to Catch On

Back in the early 2000s, Sigma -- a company usually known in the photography community as a lens manufacturer -- released a new type of camera sensor named the Foveon X3. This sensor technology was first patented in 1999 by a company called Foveon, Inc. (later acquired in 2008 by Sigma) and featured an innovative color perception technology: a 3-layer stack of photosensitive diodes.

Image Quality is More Than Megapixels

The megapixel count of a camera is often viewed by consumers to be the benchmark number for telling whether or not that camera is "good." If that were true, however, why do photographers not just buy a 108-megapixel smartphone to use as their primary equipment? The answer: because image quality has to do with far more than just megapixels.

Why Camera Sensors Matter and How They Keep Improving

What is the most important aspect of a camera to consider when looking to buy a new one? In this video, Engadget put camera sensors in the spotlight and reviewed how they have improved and what role they play in today's photographic equipment.

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?
