SW3(FL) |
|
|
ENG |
| |
It is an |
| |
image due to mismatch between the vertical sync frequency |
|
|
and the |
|
|
|
| |
It is used when the camera and broadcasting system within |
|
|
its own region do not match each other. If set to ON, the |
|
|
electronic shutter speed stays at either 1/100sec (NTSC) or |
|
|
1/120sec (PAL). |

If SW1 (ELC) is set to ON, the
SW1(ELC)
Use this for the manual iris lens. If set to ON, the electronic shutter speed varies between 1/60 and 1/120,000 second to keep the screen brightness proper. However, you must position this switch to OFF if you are using the auto iris lens (DC control type). Because, in this mode, the camera can show the color rolling effect when operating under the mechanical fluorescent lightning. If this happens, apply the AC power and set the L/L to "EXT". (NTSC: 60Hz, PAL: 50Hz)
SW2(BLC)
Use to compensate for a display that is too bright or too dark when indoor lighting or windows reflects against the
subject. Set to ON for these conditions.
SW4(AWB)
ON(ATW): It automatically adjusts the image color according to the temperature change of the lightning color. Under a very irregular lightning condition (such as car headlight), if set to ON, it captures a subject normally (white).
OFF(AWC): It remembers the normal color temp switch with the OFF to operate at a certain white balance level.
Note that AWB can cause an error in the following conditions:
-If a big subject of a uniform color with a high saturation exists in the center of the screen or if few part of the image is in white.
-If the lightning is made of special material like sodium.
