Basic parameters and commands
This chapter illustrates the basic configuration options and general commands
available for the user, being important for the operation of an ex factory pre-
configured camera. Most probably the information stated here will be sufficient
for most of the users.
Automatic correction data set selection (k)
You can use this automatic data set selection / calibration (one-time or timer
controlled repeating) to do an automatic correction on your data. The auto-
matic process tries to determine the best data set
S (if several available) and
activates it.
Criterion for the data set selection is a statistics value that is correlating with
the fixed pattern noise (vertical stripe structure), being visible within the
image. For the determination of this statistics value an image is recorded and
stored by means of the first Integrator / Image Memory module in the chain. This
acquired image is tested in succession with each correction set being available
in the memory by determining the statistics value of the corrected data. Finally
that memory page
S becomes activated, which is showing the best results for
the statistics value.
Depending on the number of available data sets the automatic data sets and the
current frame rate the automatic data set selection can take some seconds.
During the data set selection, the image output is stopped by suppression of the
FVAL signal. This procedure needs images from the camera. This means that
either Continuous Mode or Image On Demand Mode with a periodic trigger sig-
nal must be active. According to each image content, under the same conditions
diverse correction sets can be chosen if they are very similar to one another.
Usually, the automatic data set selection activates a good correction data set
but not always the best possible one. Use the command
S instead of k to
manually adjust the correction data set number. Depending on the camera
model and current
j parameter configuration, the actions accomplished by
the k command and its output at the serial interface may vary.
