Sony FCB-EH3100 Video Colour Zoom Camera
Features:
The CMOS video camera provides 2,000,000 effective picture elements
(pixels) that can shoot high-definition images to offer superior
picture
quality.
* The camera is compatible with 8 formats, including the Full HD
(1080i high definition) video format, which is equivalent to an
HD-TV broadcast.
* HD: 1080i/59.94, 1080i/50, 720p/59.94, 729p/50
* SD: NTSC (CROP), NTSC (SQUEEZE)
* PAL (CROP), PAL (SQUEEZE)
* Video outputs
* HD: Analog Component, Digital (LVDS)
* SD: VBS, Y/C
* The camera is equipped with an ×10 optical auto focus zoom lens.
* The ×12 digital zoom function allows you to zoom up to ×120,
combined with a optical zoom.
* An infrared (IR) Cut-Filter can be disengaged from the image path
for increased sensitivity in low light environments. The ICR will
automatically engage depending on the ambient light, allowing the
camera to be effective in day/night environment.
* The VISCA is a communication protocol, which enables the camera
to be controlled from a computer.
* You can select the baud rate from among 9600 bps,19200 bps, or
38400 bps. This allows you to remotely control the camera at a high
communication speed.
* The position preset function allows the camera to store up to six
combinations of settings of camera shooting conditions. Also, the
custom preset function allows you to customize the initial settings
of each function when the power of the camera is turned on.
Sony FCB-EH3100 Specifications:
In general:
* Power On/Off
Powers the camera on and off. When the power is off, the camera is
able to accept only the lowest level of VISCA Commands; the display
and other features
are turned off.
* I/F clear
Clears the Command buffer of the FCB camera.
Clearing the buffer can also be carried out from the control
application software when the power is on.
* Address set
VISCA is a protocol, which normally can support a daisy chain of up
to seven attached devices. In this case, if addresses from 1 to 7
are assigned to each of
7 devices, you can control seven cameras with the same personal
computer. However, the FCB camera does not support connection of
cameras in a daisy
chain. Therefore, whenever a camera is connected for the first
time, be sure to use the address set to confirm the address.
* ID Write
Sets the camera ID.
* Mute
Blanks the screen and sends out a synchronizing signal.
Zoom
* The camera employs an 10× optical zoom lens combined with a
digital zoom function allowing you to zoom up to 120×.
* Lens specifications: Optical 10×, f = 5.1 mm to 51 mm (F1.8 to
F2.1)
* The horizontal angle of view is approximately 50 degrees (wide
end) to 5.4 degrees (tele end).
* Digital Zoom enlarges the center of the subject by expanding each
image in both the vertical and horizontal directions. When 12×
digital zoom is used,the number of effective picture elements in
each direction reduces to 1/12 and the overall resolution
deteriorates.
Focus
Focus has the following modes, all of which can be set
using VISCA Commands.
* Auto Focus Mode
The Auto Focus (AF) function automatically adjusts the focus
position to the high frequency content of the picture in a center
measurement area, taking into
consideration the high luminance and strong contrast components.
The minimum focus distance is 10 mm at the optical wide end
(extreme close-up settings with VISCA control) (distance from the
front end of the lens).
Normal AF Mode
This is the normal mode for AF operations.
- Interval AF Mode
The mode used for AF movements carried out at particular intervals.
The time intervals for AF movements and for the timing of the stops
can be set in one-second increments using the Set Time Command. The
initial value for both is set to five
seconds.
- Zoom Trigger Mode
When the zoom is changed with the TELE or the WIDE buttons, the
pre-set value (initially set at 5 seconds) becomes that for AF
Mode. Then, it stops.
* Manual Focus Mode
MF (Manual Focus) has both a Standard Speed Mode and a Variable
Speed Mode. Standard Speed Mode focuses at a fixed rate of speed.
Variable Speed Mode has eight speed levels that can be set using a
VISCA Command.
To stop the required operation after sending a Standard Speed
command or a Variable Speed command, send the Stop command.
* One Push Trigger Mode
When a Trigger Command is received, the lens moves to adjust the
focus for the subject. The focus lens then holds the same position
until the next Trigger Command is input.
* Infinity Mode
The lens is forcibly moved to a position suitable for an unlimited
distance.
* Near Limit Mode
Can be set in a range from about 4.5 m (2000) to 1 cm(C000).
The focus range is narrowed by excluding the unnecessary range.
White Balance
White Balance has the following modes, all of which can be set
using VISCA Commands.
* Auto White Balance
This mode computes the white balance value output using color
information from the entire screen. It outputs the proper value
using the color temperature
radiating from a black subject based on a range of
values from 3000 to 7500K.
This mode is the default setting.
* Indoor
3200 K Base Mode
* Outdoor
5800 K Base Mode
* One Push WB
The One Push White Balance mode is a fixed white balance mode that
may be automatically readjusted only at the request of the user
(One Push Trigger),assuming that a white subject, in correct
lighting conditions and occupying more than 1/2 of the image,is
submitted to the camera.
One Push White Balance data is lost when the power is turned off.
If the power is turned off, reset the One
Push White Balance.
* Manual WB
Manual control of R and B gain, 256 steps each
