What is Fixed-pattern noise?
Noise that appears in the same place every time, caused by variations between pixels or readout circuits. It is removed by correlated double sampling or calibration.
Fixed-pattern noise in the explanations
Fixed-pattern noise comes from pixel-to-pixel variations in amplifier offset and dark current and from column-to-column variations in readout circuits and ADCs, appearing at the same places in every frame; column variations show up as vertical stripes.
