> A=FF[CR]
In this case, the special parameter value FF is not a file number, but starts an
integration of 64 single images and transfers the result into the correction stor-
age. The initially adjusted file number remains unchanged.
After acquisition of new reference images, the set values J (or K) should be
adjusted to the mean value of the corresponding reference image to reduce a
gain or offset leap when switching between different correction data sets.
In order to stop the influence on the correction result of each other reference
image following the new recording of only a single reference image, the two
point correction can be operated via
E=4 or E=5 as a simple one-point cor-
rection (background correction).
The newly recorded reference images are kept within the volatile correction
data storage (SDRAM) and will be lost when switching off the camera.
Background correction (U, M)
The module background correction is closely related to the module integrator
/ image store at the beginning of the processing chain (
H). It also compre-
hends an image integration function. Additionally it can subtract its current
correction data image (
H/U) from the incoming image and add the offset M.
Thus a fixed pattern noise reduction or difference image calculation is possible.
