Internal bias/dark subtracts of any ASI cameras?

topboxman

I am wondering if any ASI cameras do some kind of internal bias/dark subtract with some kind of lookup table?

My answer would most likely would be "No".

Just curious.

Thanks,

Hi Sam,

Thanks for your prompt reply. I just wanted to clarify your response. Are you saying that ASI cameras have look up tables just for hot pixels? In other words, for every frame capture, each frame will be subtracted from hot pixel look up table?

Thanks,

Peter
