Black Balance Adjustment; Shutter Settings - Sony DXC-D30WSP Service Manual

Black Balance Adjustment

Correct adjustment of the black balance is important
for optimum operation of a video camera. It is
necessary when using the camera for the first time or
after a significant period out of use, and also when
there has been a sudden change in temperature.
The adjustment value is saved in memory, and
readjustment is not normally necessary after powering
the camera off or simply when lighting conditions
change.

Notes
• When using a camera control unit, if the W/B
BALANCE switch of the camera control unit is set to
MANUAL, it is not possible to carry out black
balance adjustment on the camera.
• When using a CCU-M5/M5P Camera Control Unit,
make sure that the MODE switch of the CCU-M5/
M5P is in the CAM position.
If black balance adjustment cannot be
completed automatically
The warning message "AUTO BLACK -NG-" appears
in the viewfinder.
Make the necessary corrections, then carry out the
process again.

Shutter Settings

This section covers the settings for electronic shutter
speed, CLS (clear scan ) and EVS function.
The new value for the shutter speed or clear scan
frequency and EVS setting remains set until changed,
even when the camera is powered off.
Shutter speeds
There are five shutter speeds, from 1 / s (DXC-D30)
100
1 1
or / s (DXC-D30P) to / s. Increasing the shutter
60 2000
speed reduces blurring when shooting a fast-moving
subject. It is also possible to reduce flicker when
shooting under fluorescent lighting by changing the
shutter speed.
CLS (Clear Scan) function
When shooting a computer screen or projected image,
horizontal bands may appear in the camera image.
This is because the vertical scan frequency of the
computer-generated image is different from the
vertical scan frequency of the video system. The clear
scan function allows you to select a vertical scan
frequency to reduce this interference.
EVS (Enhanced Vertical Scan)
This function enhances the vertical scan resolution
from 400 to 450 lines (or 450 to 530 lines) to reduce
flicker. However, this increases the aliasing.
Setting the shutter speed, CLS and EVS
function
Notes on setting the shutter speed
• The faster you make the shutter speed, the darker the
image becomes. Check the brightness in the
viewfinder, and if necessary increase the lighting
level or adjust the iris.
• When the shutter speed is very fast, shooting a high
intensity subject may cause long vertical tails to
appear on the highlights (smear).
Note on setting the CLS function
The vertical scan frequencies of computer screens
vary, and it may not be possible to eliminate the
interference patterns entirely. Note also that the
vertical scan frequency may change depending on the
software being run.
