Dynamic range adjustment
The gray value represents the number of photons captured by the
sensor. This defines the brightness of the picture. The exposure time
defines the period the sensor will be photosensitive. If you decrease
the brightness, all pixel values will be changed. As a result dark areas
might become too dark. If you reduce the exposure time, underex
-
posed dark areas will appear. In order to avoid both, we recommend
to use dynamic range adjustment with dual or triple slopes
.
Dynamic range can be extended by the dual/triple slope procedure.
Suppose, dual slope is selected, the dynamic range adjustment value
is set to 80, and exposure time amounts to 1000 µs.
In this case, the analog signal of p3 and p4 will be reset to the 2
nd
reset level after 80 percent of the complete exposure time. The sig
-
nals of p3 and p4 start decreasing with the same slope as before
but will be non-saturated at read out time.
