source involves the variations between individual pixels.
Within a CMOS image sensor, the device is designed such
that each pixel is identical to all the others.
the array, there are slight variations. These variations arise
from variations in threshold voltages and offsets of the
amplifier within each pixel. Because these can vary for each
pixel within the pixel array; they are referred to as pixel FPN.

pixel array. The information within the pixel array is read out
on a column-by-column basis through these column
amplifiers. When one amplifier behaves slightly different
from another, the entire column can be affected. When this

FPN can be calibrated off-chip by subtracting a dark
Use an averaged dark image to calibrate FPN; this
eliminates other noise sources that are present in the
dark image.
Use a different dark image to calibrate for different
operation conditions. Different operation conditions can
be changes in temperature, FOT and ROT timing, and
gain settings.
