PREFACE
Panasonic`s Colour Digital Camera GP-KR222 introduce a new level of high picture quality and resolution
through the utilization of a 1/2-inch interline CCD image
sensor having 752 horizontal pixels (picture elements),
and through the use of digital signal processing LSI`s.
High sensitivity is ensured by the use of on-chip micro
lenses on each pixel. In addition, the use of aspherical
high speed lenses further improves sensitivity. High
performance-to-cost ratio is achieved through the
extensive use of newly developed digital LSI`s.

5. AGC ON/OFF Switch (AGC ON/OFF)
This switch is used to select the gain of the video
amplifier as follows :
ON: When the lens iris is fully opened at low light
shooting, a clear picture is obtained by automatic increase of the gain.
OFF: A natural and low-noise picture is obtained
under a low light condition.
6. Automatic Light Control/Electronic Light
Control Selection Switch (ELC / ALC)
This switch is used to select the lens as follows.
ALC: Choose this position when using an auto iris
lens.
ELC: Choose this position when using a fixed or
manual iris lens.
7. Detail Level Selection Switch (SOFT/SHARP)
The detail/aperture level can be selected by this
switch. Set this switch to the desired position while
observing the picture on the monitor.
Note: The aperture is cut off at SOFT position.

8. Back Light Compensation On/Off Switch (BLC
ON/OFF)
When back light affects the picture, set this switch
to the ON position for a clear picture.
9. Automatic Tracing White Balance Control
On/Off Switch (ATW, ON/OFF(AWC))
The white balance setting can be selected as ;
ON: The white balance is automatically and con-
tinuously set by detecting the characteristic /
colour temperature of light source through the
lens and controlling the gain of red and blue
signal even if the characteristic / colour temperature varies.
Note: The white balance setting is effected by the
setting level of the ATW Control (11). (The
bluish white is obtained when the ATW Control
has been set to the B side.
OFF: The white balance is automatically set and
fixed with the condition switched to the AWC
from ATW. When the characteristic/colour
temperature of light source changes, set this
switch to the ATW ON position then set it back
OFF.
Note: The white balance setting is effected by the
setting level of the ATW Control (11). (The
bluish white is obtained when the ATW Control
has been set to the B side.
10. Power Indicator (POWER)
11. ATW Control (ATW ON, R/B)
This control adjusts the level of red and blue
colour balance even if the ATW ON/OFF Switch (9)
is set to any position. It is preset at the centre position which usually provides accurate colour reproduction.
12. Video Level Control (VIDEO LEVEL, L/H)
This control adjusts the level of auto iris control
when the ELC/ALC Selection switch (6) is set to
the ALC position, or the level of electric light control when the selection switch (6) is set to the ELC
position.
Note: This control does not work in the following
conditions
• AGC ON/OFF Switch (5) is set to OFF with the
manual or fixed lens.
• AGC gain reaches the maximum level when
setting the AGC ON/OFF Switch (5) to ON.

ELC (Electronic Light Control)/BLC (Back Light Compensation) Description
1. ELC (Electronic Light Control)
In this mode a continuously variable electronic
shutter is employed to automatically control exposure times in the CCD Image Sensor, according to
the incoming light level. When this mode is selected, fixed or manual iris lens can be used instead
of an ALC type lens.
Caution :
1. Under bright conditions such as outdoors, use
an ALC type lens as the ELC control range is
not wide enough under these conditions.
2. Under certain unique lighting conditions, the
following may appear :
• strong smear and/or blooming on high light
objects such as spot lights or windows.
• noticeable flicker in the picture and/or the
colour rendition variations.
• periodic variance of white balance
Should these phenomena occur, use an ALC lens.
2. BLC (Back Light Compensation)
ON OFF
When strong, unwanted background lighting interferes with the clarity of important scene objects,
turn the Back Light Compensation On/Off Switch
(8) to the “ON” position.
Caution :
Setting this switch to the “BLC OFF” position
is recommended in the use with the pan/tilt
head or in the object having the rapid change
illumination since the speed of lens iris
becomes slow in the “BLC ON” position.
CONNECTION
1. A power supply of 12V DC is required.
2. Connect the power cable to the 12V DC Power
Terminal on the rear panel of the camera.

Video Cable
1. It is recommended to use a video monitor whose
resolution is at least equal to the camera's.
2. Terminate the camera output with 75-ohm resistor
at the furthest end of its cable run.
A. It is recommended to use 75-ohms coaxial
cable.
(RG-59/U, RG-6/U, RG-11/U, RG-15/U)
B. Always set the last monitor`s termination
switch to 75 ohms, and set the termination
switches of intermediate monitors to high
impedance (Hi-Z) position.
C. The maximum extensible coaxial cable length
between the camera and the monitor is shown
in the table 1. Since cable quality varies
among manufactures, verify video quality
before final installation if maximum length are
to be used.

3. Wiring precautions :
• Do not bend coaxial cable into a curve whose
radius is smaller than 10 times the cables diameter.
• Never staple the cable - not even with circular staples. Mismatching will occur.
• Never crush or pinch the cable
All of these will change the impedance of the
cable and cause poor picture quality.
Caution: Always set the Flange-back adjusting ring to
fully clockwise (C-mount side) by loosing the
screw on the ring before mounting the lens otherwise the inner glass and CCD image sensor could
be damaged by the lens.
MOUNTING THE LENS
(1) Mount the lens by turning it clockwise onto the
lens mount of the camera.
(2) Connect the lens cable to the Auto Iris Lens
Connector on the camera when an auto iris lens is
used.

PREVENTION OF BLOOMING AND SMEAR
When the camera is aimed towards spotlights or other
bright lights or light reflecting objects, smear or blooming may appear. Therefore the camera should be operated carefully in the vicinity of extremely bright objects
to avoid smear or blooming.
If the camera is aimed at the sun or very bright light,
such as laser beam, for a long period of time, the CCD
image sensor may be burned in and blemishes (white
or black dots) appears on the picture.
