Electrical Gain and Offset
The Intensified Retiga Fast 1394's electrical gain and offset controls allow the user to map an image's
intensities of interest to the camera's digital range. This mapping is performed in the analog domain
and thus avoids the quantization errors incurred when the mapping is performed in the digital
domain.
Most users wish to operate the camera in a mode that maximizes dynamic range. The factory default
electrical gain and offset are calibrated values that maximize the dynamic range. The electrical gain
and offset can be controlled in software by the CCD Gain and Offset controls.
