I am using Reactivision for an arts project. It involves a few still markers which are changed occasionally for other markers but can sit motionless for long periods. The issue is we seem to get after burn images after a long time in operation but restart and reconnection seems to fix it. We have unibrain fire-i firewire ccd cameras. Lighting is with a couple of infrared led arrays. As this goes away is it possible it is actually a software issue rather than hardware ( i didn't think it was possible to create after imaging with CCD's?). I looked at the source code but can't find any obvious long term memory. Aside - The adaptive threshold is kind of weird as it attempts a local threshold even if the lighting is extreme or saturated from what I can tell of the source. Any pointers appreciated.
