When I first saw the posted image of a lighting strike captured using a Sony CMOS HDV camcorder I notice what looked very much like "horizontal SSE." The bottom 1/3 looked darker than the top 2/3 of the image.
Since the Sony CMOS chip has 3 read-out ports -- the 1/3 division made sense -- just as the twin read-out ports on the HD100 CCDs give rise to 1/2 -- 1/2 split-screen.
This got me to thinking about Image Sensors and "their artifacts." For example, CCDs smear but CMOS does not.
So I've started "The Sensor Sessions" at: http://www.gyhduser.com/
The first two sessions cover CMOS. Then we'll look at Interlace Scanning for CCD and CMOS chips.
Then I'll cover Progressive scanning and lastly I'll look inside the HD100 CCD/DSP system to provide an undstanding of SSE and how to control it.
Obviously, I can't post a copy of each Session here -- so I'll post this one link for those who are interested in such topics.
