POWER WHITE BALANCE AGC ELC CAMERA
(1) “POWER”
A power on/off switch. When power is turned on, the
pilot lamp on the power switch will light.
(2) "AGC"
AGC ON/OFF Switch.
The AGC (Automatic Gain Control) switch is to increase
sensitivity electrically in low-light situations.
Set "AGC" switch to "ON" when illumination is not
sufficient on the subject. Normally, put it "OFF"
position.
(3) "WHITE BALANCE"
The picture taken with a camera is sometimes adversely
influenced by the quality of the light illuminating the
subject. To obtain fine color images, it is necessary to
adjust color balance (white balance) in the camera's
video circuit depending on the quality, or color
temperature, available from such illuminating sources,
e,g. morning, midday, evening, and fluorescent lamp.
When making adjustment on "WHITE BALANCE", select any
one of "AUTO SET"/”AUTO”/”MANU”.
-3-
* "AUTO" (Automatic follow-up system)
The purpose of this white balance of "AUTO" is for a TV monitoring
system, which installed to shoot a scenery
with wide angle. This automatic white balance adjust-
ment is performed by the detection of the average
picture levels of red(R), green(G), and blue(B) signals picked up from
the subject while they are balanced.
Under the proper condition, this incorporated function
is automatically compensated and follows up the white balance for
color temperature even when the camera is panned during shooting,
changed the color temperature of
a light source or changed ambient condition while "AUTO" position.
However, this control system is not always perfect, for example, under
a fluorescent light or when shooting and closing up a subject with
large colored area, this
control system cannot work properly and also cannot
obtain good color-imetry (color reproduction).
The purpose of the "AUTO" position is for TV monitoring system for a
scenery with a wide angle. If white balance adjustment ,is not
possible, use "AUTO SET" position.
* "AUTO SET" (Data holding)
Turning to "AUTO SET" after adjusted the white balance
for one or two seconds at "AUTO" position taking white subject, e.g.
white wall or white paper, the data of the white balance will be held.
And the white balance is
not change anything even if changed the illumination on subject and
the data will be held for about 5 hours
backing up the data.
Normally, set it "AUTO SET" position.
If you shoot more than 5 hours after the last white adjustment, or
when lighting conditions change,
re-perform white balance adjustment.
* "MANY" (Manual)
Turning to "MANU" position, take a white object such as
a white paper or white wall all over the screen and
adjust the white balance with the knobs of (R) and (B)
-4-
while watching the color monitor. For more information
on color temperature and white balance, refer to the
supplemental information of pages to and 11.
* "ELC" (Electronic Light Control)
This camera is provided with an automatic sensitivity
control which adjusts the shutter speed according to the
amount of light entering the lens so that correct
exposure is obtained even when illumination of the
object changes. Fixed shutter and manual control are
also possible.
3-3 Camera control unit (rear panel)
Following adjustments are located at the rear panel on
the camera control unit.
AGC LEVEL FUSE
VOLTAGE SELECTER
(1) "SHUTTER" (Electronic shutter)
Switch for an electronic shutter. It is available when
"ELC" switch is turned off on the front panel.
Usually, put "OFF" position which is set a shutter speed
of 1/50 sec.
When a subject moving at high speed is shot by the
camera, select any one of shutter speeds of 1/50, 1/125,
1/250, 1/500, 1/1,000, 1/2,000, 1/4,000, 1/10,000 sec. as
necessary.
* "F.L" (Flickerless)
Where the illumination of fluorescent lamps are used in
the power frequency area of 60 Hz, a flicker may appear
on the picture. And if turned to "F,L" position, it will
be set the shutter speed 1/120 sec., resulting in
decrease the flicker on the picture.

For more information on electronic shutter and ELC
(automatic sensitivity control), refer to the supple-
mental information of page 12.
(2) AGC LEVEL
When the input of video signal is rated, the output
signal should be adjusted the same level as when AGC is
"ON" and when it is "OFF".
(3) VOLTAGE SELECTER
When supplied voltage of AC INLET is AC 220 240 V, put
the voltage selecter position that appears "230V". And
the voltage is AC 100 120 V, put the position of "115V".
When you switch the voltage selecter, you should use
a minus screw driver for M3 screw. And pull up or down
a knob or the voltage selecter with the screw driver.

4-2 Camera control unit (rear panel)
There are thirteen connectors at the rear panel on the
camera control unit.
Figure Camera control unit rear panel
(1) "R OUT","G OUT",”B OUT" (RGB video outputs)
R,G and B video signals are output individually from
the BNC type connectors. They can be connected the
use of the monitor provided R,G and B individual input
terminals.
(2) "SYNC OUT”
Use it when other equipments required pulses SYNC to be
synchronized with the camera.
When the external sync-operation, the pulses of SYNC are
regenerated inside of the camera control unit and are
output. When no pulses from outside (at the internal
sync-operation), SYNC generated inside are come out
together from the "SYNC OUT".
-8-
(3) "Y/C OUT” (S-terminal)
Y (lumminance signal) and C (chrominance) are output
from the "Y/C OUT" individually.
The employment of an S-terminal allows reduction of
cross color, dot disturbance, and color blurring that
may occur especially during picture editing, compared to
the PAL composite video signal.
Use the equipments with S-terminal in the system.
(4) "VBS OUT1", "VBS OUT2"
The PAL composite video signals are come out from these
connectors which are employed BNC type.
(5) "CHARACTER"
This connector is used to connect the character
generator "TGR-325" that is made by SONY CO.LTD.
(6) P.E.(Protective Earth)
Only use for P.E.
(7) "HD IN",”VD IN", "VBS IN" (Input pulses for external sync)
When required external sync-operation between other
equipments, use any one of pulses for HD/VD, VBS or SYNC.
And input HD pulse from the "HD IN" connecter and VD from
"VD IN" connector for HD/VD external sync operation. And
input VBS or SYNC from “VBS IN" connector for external
sync operation by VBS or SYNC. When used HD/VD or SYNC,
the system should be synchronized for HD and VD phase.
When VBS, the system should be synchronized for HD, VD
and SC phase also.

5, SUPPLEMENTAL INFORMATION
(1) "Color temperature"
Light is composed of various color components in differ-
ent proportions. A relationship exists between tempera-
ture of a light source and the components of the emitted
light; as the temperature rises, the color of light
varies from red, orange, yellow, white to blue in that
order. "Color temperature" is a value that expresses
differences in color among light sources, measured in
Kelvin degrees. Bluish light has a higher color
temperature than reddish light.
(2) "White balance"
Making the colors look natural on TV monitor is what
white balance is all about. Because a camera is not as
adaptable as the human eye, if a light source is reddish,
white subjects in that light are recorded as reddish.
White balance adjustment is performed to compensate for
color temperature variations of light so that whites are
reproduces as white. Correct white balance makes all
other colors correct.
The CS5131P can perform automatic white balance adjust-
ment with just the press of a switch.
However, if illumination is insufficient, white balance
adjustment cannot be performed. To obtain correct colors,
therefore, sufficient illumination is essential.
(3) How to get good color pictures.
The simplest way is to provide sufficient lighting(close
to the camera's reference illuminance) and accurately
adjust the camera to the color temperature of that
lighting.
If light sources of different color temperatures are
used together, accurate white balance adjustment is very
difficult. For example, if natural light is mixed with
some artificial light, which is likely to occur next to
windows, correct colors of the subject are difficult to
obtain. It is recommended that incandescent or halogen
lamps not be used together with flourescent lighting.
-10-
(4) Color temperature of various artificial lighting.
(5) CCD image sensor
CCD, as the nucleus in the camera, converts lens-caught
optical images to TV signals. This device ithe product
of the latest semiconductor technology. Minute pixels
of 400,000 (active pixel consists of 752 X 582) or so are
integrated in ultra high density on the small area of
6.4mm(H)X 4.8mm(V) by utilizing sophisticated semi-
conductor technology. As shown in Figure four comple-
mentary color filters of yellow(Ye), cyan(Cy), magenta
(M), and green(G) are placed precisely one on top of
another in a zigzag manner on one picture element so
that color analysis of the subject can be made and
fundamental color signals of red(R), blue(B) and green(G)
are picked out in the color demodulation circuit.

The spectral transmittance characteristics of each color
filter are shown in Figure below. This spectrum offers
high color-fidelity reproduced images. The horizontal
resolution of 450 TV lines for the luminance signal (Y)
is confirmed by a reproduced Retma chart on a television
monitor with this complementary mosaic color filter-
arrangement.
Figure spectral transmittance of the color filters
(6) Smear
When the strong light hits the CCD image sensor, the
image of bands in vertical direction may appear above
and under the spot. This is called smear. Especially if
the camera shoots under the noon sun or its reflections,
a candlelight in the dark, or headlights of cars, this
smears may stand out in the picture.
The CCD used with the C55131P is designed against the
smear. However, watch out for smear when shooting
involves a strong light sources.
(7) ELC (Electronic Light Control) and AGC (Automatic Gain
Control)
When a camera is directed toward a subject, the most
proper combination of shutter speed and lens aperture is
automatically determined in accordance with the bright-
ness of the subject. This is the program AE (Automatic
Exposure) mechanism incorporated in an ordinary 35mm
still camera. Meanwhile, just like in a 35mm camera,
-12-
the program AE mechanism housed in the video camera
automatically selects the speed of the electronic
shutter depending on the lighting. Simultaneously, the
amplifier gain in the camera instead of the lens
aperture (iris) value is likewise automatically adjusted
according to the pre-selected shutter speed to obtain
the most appropriate video signal level.
(8) Lenses
Generally, there are many kind of lenses for the video
camera on the market, for example, different aperture
(iris), different focal distance, zoom lenses and so on.
Those having a shorter focal distance are called "wide-
angle" lenses, and those having a longer focal distance
are called "telephoto". Lenses of different focal
distances have special characteristics and you can take
advantage of these in shooting. When the camera is
fitted with a zoom lens, it is extremely easy to vary
the focal distance. Anyhow, make choice of the most
appropriate lens for your application or system.
