Software FPN Correction
The procedure is as follows:
1. Adjust the black level with the help of histogram
by modifying DAC offset.
2. Store a dark image by closing the lens aperture,
but make sure no value is absolute zero.
3. Subtract the dark reference image from all the
captured images.
Off-Chip PRNU Correction
Pixel response non-uniformity (PRNU) is also a kind of
spatial noise. It refers to the slight variations in response to
the same input that each pixel has due to the slight active
response variations between the amplifiers within different
pixels. Even though every pixel is carefully designed to
match one another, slight variations in processing, noise,
and other areas can cause these amplifiers to behave
differently.
This is corrected with the help of a grey image; the
correction is done by equalization of gain.
The procedure is as follows:
1. Capture the grey image under the same condition
as the dark image.
2. Open the aperture of the lens to allow light and
then capture the grey frame. All the pixels in the
grey image should have a grey value of
approximately 70% white (histogram should peak
at 70% white and the distribution should be
uniform around the peak as much as possible).
This grey image is stored.
FPN and PRNU correction formula:
Vn = (Avg(Wn) / [Wn - Bn + 1]) x (Gn - Bn)
Vn - data of a pixel after a calibration
Gn - data of a pixel before carrying out a calibration
Bn - black calibration data of the pixel
Wn - white (gray) calibration data of the pixel
