hello

what could be the causes of the FPN-like row noise on the cmv12000?

Bertl_oO
intracube: not sure what exactly you are referring to?
77
15:52
Bertl_oO
the noise in the second column looks like the dynamic noise from the bad voltage regulator inside the CMV12k
78
15:52
Bertl_oO
this should be fixed in the next sensor frontend we build, as we now know that it exists and how to mitigate it
79
15:58
intracube
Bertl_oO: yep, the second column
80
15:58
intracube
"After subtracting two dark frames (taken at a few seconds one after another), the image still has a really strong row noise (visually similar to FPN, but it's not fixed - it changes every frame). This one is hard to correct. CMOSIS recommends using the optical black areas for this, but they are way too small"
81
15:59
intracube
great to hear this has been resolved :)
82
15:59
Bertl_oO
yes, I think 95% of that noise should not be present anymore
83
15:59
Bertl_oO
but we'll see if we get there :)
84
15:59
intracube
cool
85
16:00
intracube
although as it says in that post, the images have been normalized, so even with the alpha cam, the effect appears far worse than it is
86
16:01
intracube
"All graphs have brightness stretched... They show how uniform the noise is, not its magnitude."
87
16:02
Bertl_oO
yes, of course, it makes sense to boost the range to see how the noise behaves
88
16:04
intracube
right
89
16:04
intracube
doesn't remember seeing the fluctuating row noise on the alpha footage
90
16:05
intracube
only some residual (fixed) FPN
91
16:05
Bertl_oO
it is noticeable in single frames
92
16:05
Bertl_oO
you do not see it in a sequence as it changes from frame to frame (and it is rather subtle)

what do you think about calling the camera "servicable"?
112
19:37
comradekingu
Most things only have user manuals, this is quite like a service manual thats extencive
113

120

no, not really, we just discussed the analysis alexML did
