An adaptive dual range analog to digital converter particularly adaptive for use with film scanners employs a set-up parameter input arrangement for receiving externally generated control signals for adjusting the digital quantization step size of the analog to digital converter to compensate for quantization errors. According to a further embodiment of the present invention, the adaptive dual range analog to digital converter further includes an input signal range selection device for selecting a segment of the input analog signal to be converted to digital form using fine resolution quantization.
