2-8 Operation with viewfinder on the shoulder
If the optional VF attachment is mounted, it is possible to attach a 2-inch color view fi nder and use as a portable camera on the
shoulder.
The view
fi nder displays the menu, camera photography information and the VF marker.
Camera photography information : GAIN. ND/ECC fi lter position, AWB channel, SHUTTER speed, EXTENDER, IRIS,
VF Markers: Frame marker, safety area marker, center marker, zebra indicator
2-9 SIGNAL Color Bar
Includes broadcast-use HDTV color bar (ARIB STD-B28) signal emitter as established by ARIB (Association of Radio Industries
and Businesses). Ideal for setting the various image levels before photographing and after recording.
2-10 BBS (Black Burst Sync) External Synchronization
In addition to using HD tri-sync, external synchronization is possible with SDTV VBS and BBS.
2-11 AVC (Auto Video Level Control)
This is a function for the combined use of auto-iris, auto-gain-control and fi lter servo to carry out automatic control to constantly
maintain the appropriate image level. If the iris goes to the close side during auto-iris operation, the ND fi lter is used to lower
the light. If it is on the open side, the ND fi lter is eliminated to increase the intrusive light. If the iris is open with all ND fi lters
removed, auto-gain control is started.

DAY MODE NIGHT MODE
When used with a remote control camera stand, unmanned operation is possible.
DAY MODE : Automatic changing of ND
fi lters from 1 to 2 is possible with a combination of the iris and the ND fi lters.
The iris convergence level can be varied over fi ve stages.
NIGHT MODE : Seamless gain increase is possible with auto-gain control. The gain increase convergence level can be set to
four different stages.
2-12 ATW (Auto Tracking White Balance)
In addition to the one-push type AWB, the camera includes ATW for auto-tracking. Automatically adjusts the white balance for
outdoor photography, where the color temperature changes.
2-13 Digital Extender
Extends the screen center (possible to choose the magni fi cation rate from the camera menu: 1.5x, 2x, 3x, 4x, 6x, 10x).
If the digital extender is turned on, the resolution deteriorates, the higher the magnification .
2-14 Remote Control
From the OCP-200 control panel, etc. it is possible to carry out controls required for operation as well as all controls required for
use as a broadcast camera, such as GAIN, GAMMA, FLARE, KNEE, DTL, PED, MTRIX, etc. (OCP-200 maximum cable length:
80 m).
In addition, by switching the camera menu it is possible to respond to ISCP commands (usually known as U4 commands). It is
possible from an external remote control panel, such as a camera platform, etc., to carry out controls required for operation. (When
inserting in a compact camera platform housing, such as an U4-SP, in order to avoid protrusion to the back of the connector plug,
an attachment option is required for the Up CN Box moving to the upper section. In this case, HD SDI OUT is a single system).
2-15 Optical Fiber Cable Extension
By connecting the optional FE-100A series HDTV optical extension device, long-range extension up to a maximum of 500
meters is possible with a single optical
fi ber camera cable. In addition to controls from the operation control panel, intercom
communications and power supply are possible. And, by means of a separate power supply to the camera, the cable can be extended
up to 2 meters.
