Exmor
Encyclopedia
Exmor is the name of a technology Sony
implements on some of their CMOS
image sensors. It performs on-chip analogue/digital signal conversion
and two-step noise reduction
in parallel on each column of the CMOS sensor. It can help to reduce the amount of "seen" pixels when you're zoomed in on a photo.
Exmor should not be confused with Exmor R, Sony's trade name for backside illuminated sensor technology, which is restricted solely to small, high-density sensors for compact cameras, cellphones, etc. Unlike Exmor R, Exmor is not limited to use in smaller sensors, and its benefits are just as applicable in the larger APS-C sized sensors featured in DSLRs.
