on page 40) 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
correction 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
.
In case that 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
. In case that only one cor-
rection 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:

Note
Changes to
J
and
K
can not be stored to file
N
