There is also channel 1 (designed for the fixed-pattern noise correction that we do not use currently), you may re-use it for processing of the data. It should be not that difficult to change the direction if needed (it was intended to read fixed-pattern noise data from the SDRAM and combine it with incoming sensor data - 8 bits for (scaled) subtraction and 8 bits - for (also scaled: ( 1+k*data)) multiplications. The multiplicative FPN in the modern sensors is rather low, we used it when dealing with the MCP image intensifiers with fiberoptic tapers bonded directly to the sensor chip - in that case the FPN modulation was very strong. > > Only for your information: Our Reasearchprojects are not so interestet > in storing the captured image und doing a jpeg compression.
