FOVEON® X3™ image sensor brings new vision to
digital imaging.
The FOVEON® X3™ image sensor is the heart of the first
and only
pixel sensors, stacked to take advantage of silicon’s ability to absorb red, green and blue light at different respective depths. A FOVEON® X3™ image sensor can thereby capture full color and detail at each and every pixel location.
The results are a revelation : better color detail, fewer color artifacts and three times the image sharpness, compared to that delivered by more conventional image sensors.

Founded in California in 1997, FOVEON Inc. is world - renowned for image sensors, user interfaces, and image/digital processing technology.
Other image sensors are no match for the SD9’s
true full - color capture system
Unlike the SIGMA SD9, other digital cameras’ image quality is inherently compromised. Conventional image sensors use
a single layer of pixel sensors which are organized in a
