An active-pixel sensor (APS) is an image sensor, which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. [1] [2] In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as ...

The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.
CMOS sensors are designed to capture and process visual information for a variety of applications. They are integral to digital imaging technologies, including those found in smartphone cameras, webcams , most modern digital compact cameras, and the majority of digital single-lens reflex (DSLR) cameras.

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.

They are regarded as nearly identical sensors 8: The Samsung Galaxy S9 and S9+ utilize either one of two sensors: the Samsung S5K2L3 or the Sony IMX345. Both feature stacked LPDDR4 DRAM in the CMOS sensor. 9: The Galaxy S8 family utilizes either one of two sensors: the Samsung S5K3H1 or the Sony IMX320. They are regarded as nearly identical ...
In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors.These MOS capacitors, the basic building blocks of a CCD, [1] are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges.
