page 39) actually being activated. Following the storage ( X=1) and a re-start
of the camera all file numbers following A and B are loaded into the correc-
tion data memory as mentioned above. For an optimum image quality one
should take into consideration that the parameters
A and B shall always
specify a pair of two mating reference images, even though these parameters
are alterable separately.
Example
Loading of correction data at low reference temperature into the active correc-
tion memory page of file number 0x20.
> A=20[CR]
The set values for both reference images A and B are adjusted with the
parameters J and K. For each correction data set two registers are available
which include the corresponding set value. One always refers to both set values
of the actual correction data set
S.
If various correction sets are obtainable, the set values are factory-bunched in
one file, the number of which is indicated by the parameter
N. If N is not zero,
the values for all correction sets from this file are loaded, when switching-on
the camera and stored back with
X=1. If only one correction data set is on
hand, N can remain on the value zero, because J and K (only the values
of the actual memory page) are stored together with all other parameters of one
system file apart from the file N.
Example
All set values of the two-point correction have to be loaded from the file 0x60.
> N=60[CR]
Generally no changes at the set values have to be executed. The factory-deter-
mined value
J (or rather K) for a determined correction image, as well as the
definition of the conversion of temperatures in digital values, can be gathered
from an optional calibration report.
From the registers J and K actually only the higher 12 (Pearleye P-007
LWIR) or 14 (Pearleye P-030 LWIR) bits are used.
The lower bits are reserved for prospective extensions and should always be set
to zero:

Changes to J and K cannot be stored to file N.
