I have an STF8300M and am struggling to understand what appears to be a critical issue. When I expose an image of a lit object for a couple minutes and then expose another image for a few minutes, in a 100% dark environment, I see a 'ghost' of residual signal from the previous exposure. For my application, it is critical that there is no residual signal for subsequent frames. From digging through the SDK, it appears that residual signal should be handled automatically (I call csbigcam.GrabImage()). The signal appears to dissipate over time but is still present even after a full minute. Is there a way to force the sensor to 'reset' such that there is no signal carry over in subsequent exposures? Any input is very appreciated.
