Specifications

The parameters A and B define both files out of which the reference images
for the two-point correction data are loaded. If various correction data sets are
available, each of the reference images in the file system is stored in a closed
sequence of file numbers. The loading process following the camera start
begins at the first cold (low) reference image A. Then the loading process con-
tinues with the accompanying warm (high) reference image B.
In the following step an attempt is made to load the file numbers A+1, then
B+1, and so on. This process continues as long as one file number is missing
within the file system or the maximum number of correction sets (actually 32)
is achieved.
If, 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 pro-
cedure following the switch-on of the camera, the data are exclusively copied
within the memory page S therefore being activated (see Chapter Select a cor-
rection data set (S) on page 60).
After the non-volatile storage (X=1) and a restart of the camera, all file num-
bers following A and B are loaded into the correction data memory as men-
tioned above. For an optimum image quality, consider that the parameters A
and B will 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.
These include the corresponding set value. One always refers to both set values
of the actual correction data set S.
If various correction sets are selectable, the set values are factory-bunched in
one file, 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 restored with
X=1.
If only one correction data set is available, N can remain 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.
From the registers J and K, only the higher 12 bits are used.
The lower 4 bits are reserved for prospective extensions and should always be
set to zero:
