are normalised to the exposure time. They can be set to a maximum value of 1000,
which corresponds to the exposure time.
Examples in the following sections illustrate the LinLog
®
feature.
LinLog1
In the simplest way the pixels are operated with a constant LinLog
®
voltage which defines the
knee point of the transition.This procedure has the drawback that the linear response curve
changes directly to a logarithmic curve leading to a poor grey resolution in the logarithmic
region (see Fig. 4.12).
