The Live MOS sensor is a brand name of an NMOS Image sensor[1] used by Panasonic, Olympus and Leica in their Four Thirds System DSLR manufactured since 2006. (Olympus E-330, Panasonic Lumix DMC-L1 and Leica Digilux 3).

A reviewer claims that the sensor can achieve the same image quality as CCD-based sensors while keeping energy consumption down to CMOS levels.[1]

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 E-400, E-410, and E-500).

Also, In order to reduce the image noise problem found in the first generation of Four Thirds DSLR cameras, (Olympus E-1, E-300, E-400 and E-500) which used FFT CCD sensors[2] (due to smaller sensor size compared to the APS-C size),[3] the Live MOS chip includes a noise-reduction technology.

This sensor is also used in Panasonic's Micro Four Thirds System cameras.
