Overview of Functions

The camera control is performed by VISCA and PTP
commands. For the camera control by PTP, refer to
"Camera control PTP".
In general
• Power On/Off
Powers the camera on and off.
Although the screen is set non-displayed when the
power is off, the camera is able to accept VISCA
Command.
• I/F Clear
Clears the Command buffer of the FCB camera.
• Address Set
VISCA is a protocol, which normally supports a daisy
chain of up to seven connected cameras via RS-232C
interface. In such cases, the address set command can
be used to assign addresses from 1 to 7 to each of the
seven cameras, allowing you to control the seven
cameras with the same personal computer.
Although the FCB camera does not support direct
connection of cameras in a daisy chain, be sure to use
the address set command to set the address whenever
a camera is connected for the first time.
• ID Write
Sets the camera ID.
• Mute
Blanks the screen and sends out a synchronizing
signal.
• Lens Initialize
Initializes the zoom and focus of the lens. Even when
power is turned on, it initializes the zoom and the
focus.
• APR (Auto Pixel Restoration)
During operation of the FBC camera, the temperature
of the set rises and white flecks may be generated on
the CMOS image sensor.

Basic Functions

The APR detects and corrects the white flecks,
making them unnoticeable.
The detection function of the APR needs to be done
while white flecks are generating.
If white flecks are not being generated, such as when
the temperature of the camera is not high
immediately after the set turns on, previously
generated white flecks cannot be detected even if the
APR is used. Therefore, please be sure to use the APR
while white flecks are generating.
By turning on the APR and turning the power OFF/
ON, white flecks are detected and corrected, and then
recorded in the set.
Please be sure to turn "APR" to OFF when the APR
correction is completed. The correction data is
maintained even if "APR" is OFF.
Zoom
The FCB camera incorporates a 20× optical zoom lens
combined with a digital zoom function; this camera
allows you to zoom up to 240×.
• Optical 20×, f = 4.4 mm to 88.4 mm (F 2.0 to F 3.8)
The zoom magnification can be set in the following
methods.
Using Standard Mode

There are eight levels of zoom speed.
In these standard and variable modes, it is necessary to send
Stop Command to stop the zoom operation.
Direct Mode
Setting the zoom position enables quick
movement to the designated position.
