A traditional, front-illuminated digital camera is constructed in a fashion similar to the human eye, with a lens at the front and photodetectors at the back. This traditional orientation of the sensor places the active matrix of the digital camera image sensor—a matrix of individual picture elements—on its front surface and simplifies manufacturing.
Exmor R is a back-illuminated version of Sony's CMOS image sensor. [5] Exmor R was announced by Sony on 11 June 2008 and was the world's first mass-produced implementation of the back-illuminated sensor technology. [6] [non-primary source needed] Sony claims that Exmor R is approximately twice as sensitive as a normal front illuminated sensor.
While the first three generations of X-Trans sensors are front-illuminated, the fourth generation uses the principle of backside illumination. This improves noise levels and image quality. This improves noise levels and image quality.
Released after α6000, this is an updated version of the α5000 with a 24.3MP sensor and on-chip phase detection, the same as the α6000 but in a compact body like the Sony NEX-3/5 line. Sony claims that it is the world's smallest interchangeable-lens camera with an APS-C-size-sensor and a built-in flash, but no electronic viewfinder.
A fact from Back-illuminated sensor appeared on Wikipedia's Main Page in the Did you know column on 17 June 2010 (check views).The text of the entry was as follows: Did you know... that the back-illuminated sensor improves on conventional digital camera sensors by moving wiring so it does not interfere with light entering the front of the detector?
