The residual point noise (RPN) of the CCD is automatically compensated with the automatic compensa-
tion (APR) function usually during the automatic black balance adjustment (ABB). If the RPN still
remains after the APR is executed, perform the manual RPN compensation adjustment.
.
If any RPN still remains after the RPN compensation adjustment, handle it according to the fl owchart.
3-6-1. Automatic Compensation (APR)
When an RPN is detected in the screen, perform the automatic black balance adjustment (ABB) and
remove the RPN with the APR function.

RPNs of only one channel (R, G, or B) can be detected and compensated with one-time APR. To scan
these three channels, be sure to perform the ABB three times.
.
The log of the address data of RPNs that have been compensated is updated each time the APR is
performed. RPNs that are not detected with the APR function fi ve times in a row, they are excluded
from the scope of compensation and their data is deleted.
3-6-2. Manual RPN Compensation Adjustment
The manual RPN compensation adjustment uses the SERVICE menu.
