Bad pixel correction (C, F)
The configuration of the bad pixel correction is executed ex factory, like this
normally no access on behalf of the user becomes necessary.
The bad pixel correction applies up to six non false neighbour pixels, in order to
determine an interpolated value from the neighbours. At the position of the
defective pixel an interpolated value in exchange of the bad pixel value is out-
put.
The parameter
F
controls the operation mode of the bad pixel correction.
The following value assignment is applied:
Example
Activate the bad pixel correction.
>
F=1[CR]
By means of parameter
C
the file number of the required correction data is indi-
cated. Ex-factory the defective pixels are determined one time and the corre-
sponding correction data is stored in a special data format in the camera. As
generally only one file with correction data exists in the camera, it is not neces-
sary to change this parameter.
Example
Initialization of the correction data for the bad pixel correction from the file
0x70.
>
C=70[CR]
Value
Description
0
Bad pixel correction deactivated;
output of the uncorrected data.
1
Bad pixel correction is applied.
2
Testing mode, output of correc-
tion data. (*)

Note
(*) Operation mode
2
exists for test purposes.
In case of activating this mode the module does not transmit
any incoming image data anymore. It becomes a data source
itself instead.
