you need to make sure the offset(brightness) is big enough
otherwise some data maybe cut below 0 and cause this problem
OK, thanks. I see that you now have a buffer incorporated in you 1600 camera to eliminate amp glow when using USB2 with that camera but, I saw amp glow in my 174 using a USB3 connection. Does the 1600 have less amp glow now with the buffer and will the other camera also include the buffer to help with amp glow?
some amp-glow is from the sensor and cannot be removed such like 174
but some amp-glow is because slow transfer speed such like you connect 1600 under usb2.0 port
