Rpn Compensation; Automatic Compensation (Apr); Manual Rpn Compensation Adjustment - Sony HDC1000 Maintenance Manual

3-10. RPN Compensation

m
. The RPN compensation function is available for Soft-
ware Version 1.11 and higher.
. The residual point noise (RPN) of the CCD is
automatically compensated with the automatic
compensation (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 flowchart.

3-10-1. 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.
m
. 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 five
times in a row, they are excluded from the scope of
compensation and their data is deleted.
3-10-2. Manual RPN Compensation Adjustment
The manual RPN compensation adjustment uses the
SERVICE menu.
For how to display the SERVICE menu, refer to the
Section 5-1.
Open the MANUAL RPN[S03] page of the SERVICE menu.

Adjustment Procedure
n
Points that are adjacent laterally and diagonally to already
compensated RPNs cannot be compensated.
1. Select the channel (R, G, or B) that is to be compensat-
ed.
ITEM : RPN CH SELECT → R, G, B
2. Adjust the H and V values and set the cross cursor
center at the target RPN.
When the cursor is placed accurately at the RPN
position, the RPN is compensated.
n
Some RPNs seem to have been compensated even if the
cursor is placed off the RPNs by one line or one pixel.
Before proceeding to step 3, shift the cursor by one
line or one pixel and check that the compensation
position is correct.
ITEM : RPN CURSOR → ON
ITEM : CURSOR H POS
ITEM : CURSOR V POS

One turn of the rotary encoder is equivalent to one-
pixel shift.
On the other hand, the cursor moves by two clicks of
the rotary encoder because the cursor has a size of two
pixels.
3. Press the rotary encoder and record the RPN data
(correction value).
ITEM : RECORD RPN → EXEC
4. A message "RECORD DATA OK? YES → NO" appears.
Check that the RPN has disappeared and then select
YES with the rotary encoder.
5. Press the rotary encoder. A message "COMPLETE!"
appears and the RPN compensation starts.
n
If a compensation pixel has been wrongly recorded,
delete the RPN data.
ITEM : DELETE RPN → EXEC
6. Repeat steps 2 to 5 to compensate other RPNs.
If any RPN still remains after this manual adjustment,
handle it according to the flowchart.
Setting after Adjustment
