Not to be confused with Exmoor.

Exmor is the name of a technology Sony implemented 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.

Exmor R is a back-illuminated version of Sony's CMOS image sensor.[1] Exmor R usage is limited to smaller sensors for camcorders, compact cameras and mobile phones. It was announced by Sony on 11-Jun-2008 and was the world's first mass-produced implementation of the back-illuminated sensor technology[2] Sony claims that Exmor R is approximately twice as sensitive as a normal front illuminated sensor. This active pixel sensor is found in several Sony mobile phones and cameras as well as Apple's iPhone 4S and 5.[3][4] The Exmor R sensor allows the camera of the smartphone to capture high definition movies and stills in low lit areas.
