Advanced Parameters and Commands
This section is to illuminate the advanced configuration of the IRC-320 models. For the control of an
ex-factory set up camera the intervention within the parameters stated here or rather the use of the
mentioned commands is only necessary in exceptional cases.
10.1
Two Point Correction (
A
,
B
,
E
,
J
,
K
,
N
)
The configuration of the two point correction comprises the following parameters:
A
File number of the first correction image recorded at cold reference
temperature.
B
File number of the first correction image recorded at warm reference
temperature.
E
Two point correction operating mode.
J
Set value of the correction image of the actually chosen correction data set
recorded at cold reference temperature.
K
Set value of the correction image of the actually chosen correction data set
recorded at warm reference temperature.
N
File number for the set values of all correction data sets.
The parameter
E
controls the operation mode of the two point correction. The following value
assignments are valid:
0
Deactivated. Data is passed through transparently.
1
Activated. Correction data
A
and
B
with the set values
J
and
K
of the actual
correction memory page
S
is used.
2
Deactivated. Test mode: Correction data
A
are output as image data.
(*)
3
Deactivated. Test mode: Correction data
B
are output as image data.
(*)
4
One point correction: Simple subtraction of the correction data
A
from the
input data. In addition the set value
J
is added as offset to each pixel value.
5
One point correction: Simple subtraction of the correction data
B
from the
input data. In addition the set value
K
is added as offset to each pixel value.
(*)
Attention: Operating modes
2
and
3
exist for test purposes. In case of activating one
of these modes it has to be taken into consideration that the module does not transmit
any incoming image data anymore. It becomes a data source itself instead!
Example:
Activate the two point correction.

The parameters
A
and
B
define both files out of which the reference images for the two point
correction data are loaded. In case that various correction data sets are available the reference images
in the file system are stored each in a closed sequence of file numbers. The loading process following
the camera start begins at the first cold reference image
A
. Then it is continued with the accompanying
warm reference image
B
. In the following step it is attempted to load the file numbers
A+1
,
then
B+1
and so on. This process is continued as long as one file within the sequence is missing in the flash or
the maximum number of correction sets (actually 32) had been achieved.
In case during operation the value of
A
or
B
is new adjusted, this change causes the immediate data
load out of this file. Different to the automatic loading procedure following the switch-on of the
camera, the data are exclusively copied within the memory page
S
(see chapter 9.1, p. 21) actually
being activated. Following the storage (
X=1
) and a re-start of the camera all file numbers following
