A micrograph of the corner of the photosensor array of a webcam digital camera Image sensor (upper left) on the motherboard of a Nikon Coolpix L2 6 MP. 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.
It originally referred specifically to an NMOS sensor [2] but was later used to refer to CMOS, BSI CMOS, and stacked BSI CMOS sensors [3] so appears to generally reference active pixel sensors. Due to low energy consumption, it became possible to add the live preview function to all the Four Thirds System cameras since 2006 (except the Olympus ...

Comparison - CCD vs. sCMOS technology; lower figure compares a scientific grade CCD (left) and a pco.edge camera with sCMOS sensor (on the right) under similar weak illumination conditions. This demonstrates the superiority of sCMOS over CCD with regards to read out noise and dynamic, without smear (the vertical lines in the CCD image).
CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. [1]
MOS/sync – Sync-sound cameras are able to both maintain a constant speed (usually crystal lock) and run quietly enough not to be heard by the sound recordist. MOS cameras do not meet either one or both of these requirements, and are usually used either for applications where camera noise is not a concern, or non-standard camera speeds are ...
CMOS cameras have some advantages for electron microscopy compared to CCD cameras. One advantage is that CMOS cameras are less prone than CCD cameras to blooming, i.e. the spreading of charge from oversaturated pixels into nearby pixels. [6] Another advantage is that CMOS cameras can have faster readout speeds. [7]
Digital cinematography captures motion pictures digitally in a process analogous to digital photography.While there is a clear technical distinction that separates the images captured in digital cinematography from video, the term "digital cinematography" is usually applied only in cases where digital acquisition is substituted for film acquisition, such as when shooting a feature film.
