When using the 4x hardware gain option (HIGH_GAIN = ON), the compression may be
ineffective (the A/D converter is out of range) because the logarithmic compression is only
effective on the upper intensity values. If it is necessary to use a camera with a logarithmic
response curve, the LinLog technology will not replace it completely. On demand, DALSA
cameras can be modified to fulfil these needs.
If necessary, a look-up table (LUT) can be used to improve and adjust the characteristics to the
application. Please ask our support for more information.
