Maybe Mike will be able to capture another raw Seek Thermal thermal image for bad pixels analysis, while completed my software and made some automatic measurements how many those black dots are and which percentage looks like bad ones
Attached also 208x156 pixels version-oryginal output from my software.
The only 5 black pixels which I marked by hand from red are those pink one on left side, while they are very close to those looking good-only a tiny 1 pixel difference detected by my automated tools
There are some statistics from this image.
Seek Thermal sensor 206 x 156 black pixels: count: 2169 good: 2138 bad: 31
However, when we count those 5 pink pixels and let them be good ones, than we have in 206x156 image:
*
2143 good black pixels (2138 green+ 5 pink ) and this is what I would expect on perfect Seek Thermal sensor image raw data if all their sensors shares the same black dots pattern
*
26 bad looking (red ones)
So, when we calculate percentages we'll get:
2143/206/156 =
6.668% good black dots on perfect sensor
and
26/2143=
1.21% bad black dots in this case
It is interesting if this is really manufacturing defects or some kind of data capture errors?
Probably more samples needed from the same camera and also other Seek Thermal sensors to investigate it futher.
Maybe someone else will include there raw data from this sensor for similar analysis.
I haven't got this thermal camera yet.
BTW: On Mike video teardown it looks like there is very downgraded efective frame rate and some kind of werid averaging with horrible pixels around thermal image, so probably they forgot to cut off rest of blured image at the edges and it creates very bad looking rectangle around thermal image
They could simply make those pixels... black if do not wanted resize output image
Note: Just thinking maybe those red black pixels (they had 0 value) are simply noise from sensor itself?
Difficult to say without another sensor images analysis...
