6.4.9. Spot Noise
p
Information:
1) The SPOT NOISE adjustment compensates for bright points that appear on the screen, and these
are caused by a defect in pixel of CCD (image sensor) that may occur when DVD video camera/
recorder is used under particular conditions or for a long time. Therefore, execute SPOT NOISE
only in the following cases:
a) Pixel defect occurs in CCD and a bright point appears on screen,
b) Lens unit (CCD) is replaced
c) “Data Initialize” is executed
2) The presence or absence of a bright point that appears on screen due to pixel defect on CCD can
easily be judged by capping the lens. Use a CRT color monitor for this check.
Procedure:
1) Choose SPOT NOISE on the ADJUST MENU screen.
2) Click the EXECUTE button on ADJUST MENU screen
to start adjustment.
When SPOT NOISE starts, the DVD video camera/
recorder will automatically turn on again.
3) When adjustment is complete, the ADJUSTMENT
FINISHED dialog will appear: Click the OK button in
dialog to restore the ADJUST MENU screen.
If bright point still appears after adjustment is finished,
the lens unit (CCD) may be faulty.
