False Colour
Sensors & Digital Capture
Coloured artefacts appearing on fine detail, caused by the colour filter array sampling different colours at different positions.
Fixed Pattern Noise
Sensors & Digital Capture
Noise that appears in the same places on every frame, caused by small manufacturing differences between photosites.
Flat Field Correction
Sensors & Digital Capture
Dividing an image by a frame of evenly illuminated field to remove vignetting, dust shadows and photosite sensitivity variation.
Corrected = (light − dark) / (flat − bias)
Foveon Sensor
Sensors & Digital Capture
A sensor that records all three colours at every location by stacking three photodiode layers at different depths in the silicon.
Full-well Capacity
Sensors & Digital Capture
e⁻ (electrons)
The maximum number of electrons a photosite can hold before it saturates and stops responding to further light.
