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.
Avalanche photodiodes are photodiodes with structure optimized for operating with high reverse bias, approaching the reverse breakdown voltage. This allows each photo-generated carrier to be multiplied by avalanche breakdown , resulting in internal gain within the photodiode, which increases the effective responsivity of the device.
Under certain conditions, cameras equipped with X-Trans II and III sensors can exhibit purple flare/grid artifacts in backlit photos. [7] This occurs due to the particular arrangement of the phase detection and masking layers on the sensor. The appearance of the effect can vary with the demosaicing algorithms in use.
It color matches fairly well with the Sony A7s iii and Sony a1, with the Sony A7s iii leaning a bit green, the Sony a1 a bit magenta, and this camera between the two (tested using DCS Labs -SW - CDM 28R - v15.2 A3 color chart) and with individual white balancing, the colors are very similar.
