In this way it is possible to preserve the constant component of the image irre-
spective of the background correction’s activation state. Integrating a new
background correction image with the command

U does not modify M. Only

the 12 most significant bits of this 16-bit value are relevant.

The following table reveals the bit order:

Example

Set the background correction offset to 291 = 0x123

M=1230[CR]

Bad pixel correction (C, F)

The configuration of the bad pixel correction is executed ex factory, therefore
no access by the user is necessary.

The bad pixel correction applies up to six non-false neighbor pixels, in order to
determine an interpolated value from the neighbors. At the position of the bad
pixel an interpolated value in exchange of the bad pixel value is output.

The parameter

F controls the operation mode of the bad pixel correction.

The following value assignment is applied:
