Integrator and Image Store (
H
)
The module “integrator / image store” (integrator) is internally applied for the automatic selection of
the correction set (
k=
) and the recording of new temporary reference image data (
A=FF
,
B=FF
).
Furthermore this module may also be controlled manually. Due to the fact that the data are stored in
the volatile SDRAM memory it will get lost after the camera switch-off.
Please note that this module uses the same memory buffer as the Background Correction (
U
). It is not
useful to activate
H
and
U
at the same time.
The bits of the parameter value are divided into four different sized bit groups
a
,
b
,
c
and
d.
Each bit
group has a special function, being independent of the other ones:
•
a
: Controls the output of integrator module. Either the incoming data are subject to be passed
through transparently or the actual memory content of the integrator is output. In the latter
case the integrator becomes an image source itself. In this way this module has available a
simple image store function.
•
b
: Defines the number of images to be integrated and starts the integration process as soon as
a new value was set.
•
c
: Controls the data copy mode. The image store content of the integrator is subject to be
copied into the correction data store as cold or warm reference image of the two point
correction (parameter
A
or
B
in the active memory page
S
) at any time. The data copy mode
should stay active for a minimum period of two complete image cycles in order to guarantee a
save data transmission into the target area.
•
d
: Indicates whether the at last started integration is still running. This bit can only be read
out; during write access to
H
it is ignored.
The table below illustrates the possible values for the individual bit groups:
F E D C B A 9 8 7 6 5 4 3 2 1 0

Value (hex)
Explanation
a
0
Output: deactivated. Data are passed through transparently.
1
Output: activated. Output of actual image store content.
b
0
Integration: deactivated. The image store content is not changed.
1
Integration: 1 image. The following image is copied into the image store.
4
Integration: 8 images. The following 8 images are integrated and the result is
copied into the image store.
5
Integration: 16 images. The following 16 images are integrated and the result is
copied into the image store.
6
Integration: 32 images. The following 32 images are integrated and the result is
copied into the image store.
7
Integration: 64 images. The following 64 images are integrated and the result is
copied into the image store.
c
0
Copy: deactivated.
1
Copy: Target
A
. The image store content of the integrator is subject to be copied
into the correction data store as cold reference image of the two point correction
2
Copy: Target
B
. The image store content of the integrator is subject to be copied
into the correction data store as warm reference image of the two point correction
d
0
Integration completed. (This value can only be read out.)
1
Integration still running. (This value can only be read out.)
Note:
The Integration is activated by
change
of the register content of
H
. In case that e.g. directly following the
integration of 64 images a further integration of 64 images is subject to be started another value has to be
written into the register first. I.e. e.g.:
H=E
,
H=0
,
H=E
.
