Example
Integration of 32 images simultaneously to the output of the actual integration
image (a=2, b=6) => abbba = 11100 [binary] = 0x1A. After that, reactivate the
background correction.
Command sequence
>
U=1A[CR]
...wait for at least 34 image cycles (32 + 2 frames jitter buffer, 0.85 seconds at
40 images / second) or poll the state of bit group c with
Y=1...
>
U=1[CR]
The parameter
M defines the offset value that is added to each pixel if the
background correction is activated. By default,
M is automatically set to the
mean value of the background image, provided that the background image
acquisition is done with the automatic calibration function (
k).

Explanation
a

Output: deactivated. Data are passed through transparently.
1
Output: activated. Apply the current correction image (H/U) and offset
value M.
2
Output: activated. Output of current correction image (H/U).
b
0
Integration: deactivated. The image storage content is not changed.
1
Integration: 1 image. The following image is copied into the image
storage.
4
Integration: 8 images. The following 8 images are integrated and the
result is copied into the image storage.
5
Integration: 16 images. The following 16 images are integrated and the
result is copied into the image storage.
6
Integration: 32 images. The following 32 images are integrated and the
result is copied into the image storage.
7
Integration: 64 images. The following 64 images are integrated and the
result is copied into the image storage.
c
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 bit group b of
U.
Example: If a further integration of 64 images is subject to be started, directly following the inte-
gration of 64 images, another value has to be written into the register first.
Example:
U=E, U=0, U=E.
