6. OPERATION
Turn on the POWER switch on the camera control unit and adjust the lens iris and focus
while observing a picture on the monitor screen. To obtain the best picture quality, per-
form various settings.
6.1 AGC (Automatic Gain Control)
AGC functions “OFF”, “ON” or “UP” can be selected on the screen menu. Generally, the
camera is used with the AGC set to OFF, but when increased camera sensitivity is re-
quired, it is set to ON. When more sensitivity is required, “UP” is selected. With the AGC
ON, the camera sensitivity approximately doubles, and with the UP selected the sensitiv-
ity approximately doubles again, but noise will also increase. We recommend you in-
crease intensity of the lighting to obtain good pictures.
The AGC measurement area is the same as that used for “AREA”. (Refer to item 7.5)
6.2 White Balance
A white balance adjustment is necessary to obtain pictures with correct color tone. This
camera allows you to select the white balance adjustment of “AUTO”, “SET”, and
“MANU”. With the AUTO mode selected, the camera adjusts the white balance automati-
cally. Most shooting will be made in the AUTO mode. The color temperature applicable to
this camera is approximately 2500 to 7000K.
