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).

Output: deactivated. Data are passed through transparently.

1

Output: activated. Apply the current correction image (H/U) and offset
value M.

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.
