Chapter 6 A Quick Lesson on Camera Settings 67HDC-900/950/930 Series Product Information Manual
The following are two quick setting guides for the HDC-
900 Series: Case-1 and Case-2. The former is mainly
for applications where minimal camera operational
experience is required or for unmanned, robotic
control operations. The latter is for general operations.
6-1. Case 1 — for situations requiring minimal camera operator
experience
1. One-touch power on
Use the main switch of the power supply to turn on/off
the whole system rather than using the power on/off
switches on the individual devices for operating
convenience.
2. Stable time
Normally, a camera system can be used to start
shooting within a few seconds after power is turned on.
If the camera is connected in a large system
environment, it may require a little more time especially
for System Locking after the power is turned on.
System components that need continual system
stability, such as a sync-generator, should be in round-
the-clock operation in case it is needed to respond to
an emergency broadcasting condition.
3. Setup
Store all the data for standard camera status on a
Reference file so the camera system can be operated
under a standard condition previously set just by
pressing the Standard button.
4. Scene files
Recall desired scene files that will be used. It is very
efficient to use the scene files for patternized weather
forecasts or special corner inserts in news programs.
5. End
Just turn off the main switch of the power supply.
Notes
• Prepare reference files beforehand if necessary,
otherwise the factory set files will be stored.
• Make a scene file for every corner and file them.
• Use the main switch of the power supply to turn on/
off the camera system. Setting Color Mode or Test
Mode is not recommended because it will lengthen
the set up process time. Also, lens close is not
necessary for CCD cameras.
Usually, this kind of operation works well. So a
system check or adjustment once every 3 to 6
months should suffice.
6-2. Case 2 — for general operations
1. One-touch power on
Turn on the power for the whole camera system using
the main switch of the power supply for system
stability.
2. Camera head connection
(1) When the CCU has already been connected to
the camera head, do the heat run for 10 to 30
minutes.
(2) When the camera head connection needs to be
changed, turn off the HEAD POWER through
the CCU or RCP.
(3) Check the cable indicator on the CCU. If the
light of the indicator goes off, then you can turn
on the camera power.
(4) Turn the camera power off using the POWER
SW on the camera head side when changing
the accessories such as a lens or viewfinder.
3. Camera adjustment
(1) Press the STANDARD button to clear the data
from the last shooting, or execute Auto Setup.
(2) Perform auto white balance using a gray scale
or standard white chart.
(When shooting the scale or chart, use the
same lighting equipment that will be used for
program shooting. Be sure to direct light on the
scale or chart uniformly under standard
illumination that will be used in the studio
because it will affect the shading adjustment)
4. Keep all the cameras at the same level by
adjusting the IRIS and MASTER PED. Usually,
this step can be skipped over if the initial setting
is accurate.
5. Precise camera adjustment
(1) Previous check - Check the gray scale for any
stains, spots, cracks, or imperfections. It is
recommended to change the scale every 3 to 6
months. Be sure to keep the scale at normal
room temperature in a dark area because it is
painted with a specific pigment that may be
altered depending on its storage environment.
(2) Monitor adjustment - Perform the adjustment by
using the calibrations on the waveform monitor
and picture monitor.
(3) Color bar adjustment - Precisely adjust the
color bar level and black balance of each
camera to the same level.
(4) Gray scale adjustment - Make the R/G/B levels
be consistent with each other from black level
to white level by shooting a gray scale.
(5) In case the black balance is out of line - Check
the black balance at the time of lens close
whether it is in line or not. If not, execute Auto
Black, or adjust the R/G/B BLK to the same
level between each signal.
(6) Open the IRIS and adjust the white level to
100%. Execute Auto White or adjust RGB WHT
to make the R/G/B levels be consistent with
each other.
(7) Perform Gamma level adjustment when the
gray scale cross-point level is out of line.
(8) Perform Flare adjustment when the gray scale's
darkest level has a level difference in the low
frequency area. Even if the level difference is
around 1 to 2 stop iris in the Flare adjustment,
perform a fine adjustment to minimize the
difference. Be sure to repeat the adjustments
because the adjusted items affect each other
subtlety when using a gray scale for
fundamental adjustment.
(9) Shading adjustment - Sometimes the R/G/B
levels are not consistent with each other even
after a gray scale adjustment. This occurs when
the shading adjustment is not sufficient or when
a lens is changed.
