The BVP-900/900P Color Video Camera is a camera
head designed for a Sony CCD camera system used in
a studio and outside broadcast applications. The BVP-
900-series video camera system is composed of
independent units each of which has its unique
function like a pickup device, camera head, camera
control unit, video selector, master setup unit, remote
control panel, etc. So a wide variety of systems are
available for your special purposes.
Thanks to a newly developed CNU-700 Camera
Command Network Unit, a system can control up to 96
video cameras.
Features
Easily changeable CCD unit
The CCD unit is designed as a separate block from the
camera head so you can easily change the aspect ratio
(4:3 or 16:9) simply by replacing the unit. No
readjustment is required after the change under normal
operating conditions.
Easy-to-operate design
The new body design lowers the viewfinder position,
which decreases the parallax of the lens and
viewfinder. Also, the angle of view from the camera
operator's position is wider, as the total height of the
camera is lower than with the conventional unit.
High quality
High picture quality: A newly developed video-
processing LSI for broadcasting cameras assures a
high-quality picture required for a studio-use CCD
camera.
High signal-to-noise ratio: A high signal-to-noise
ratio has been achieved as a result of the use of a
top-performing CCD, a new video-processing LSI
and a 12-bit A/D converter.
Wide dynamic range: Automatic and manual control
capabilities for knee point and knee slope enables
reproducing high-luminance subjects clearly in up
to 600% normal light.
High sensitivity: A sensitivity of F8 at 2,000 lux
(typical) has been achieved. When the video gain
is raised by 18 dB, a video level of 100% is
obtained with minimum subject illuminance of 7.5
lux.
2 (E)
High vertical resolution: The vertical resolution can
be improved to 450 lines for the BVP-900 or to 550
lines for the BVP-900P using the EVS (Enhanced
Vertical Definition System) function. The super
EVS function enables you to adjust vertical
resolution to the desired value between 350 and 450
lines for the BVP-900 (only with the OHB-750A/
750WSA CCD Unit) or between 450 and 550 lines
for the BVP-900P (only with the OHB-750AP/
750WSAP CCD Unit).
Automatic setup and filing function
Built-in microcomputers actualize quick and precise
automatic setup, and also reduce the time required for
maintenance. The adjusted data can be stored in the
camera with a filing system.
Electronic shutter
An electronic shutter of 6 speeds (from
1
to
/
) is provided with the BVP-900/900P. You can
2000
shoot a rapidly moving object clearly by selecting the
optimal shutter speed. It also has an ECS (Extended
Clear Scan) function. Using this function, you can
adjust the shutter speed of the BVP-900 in 510 steps

BVP-900P in 607 steps (from

9000
ECS function enables minimizing horizontal streaks
when shooting a computer display screen.
Dynamic shading compensation function
When you change the zoom position with the aperture
almost completely open, the modulation shading will
appear. The BVP-900/900P can automatically
compensate for such phenomena to obtain optimum
picture quality at any zoom position. (This function is
activated only when a lens allowing this function is
attached.)
Variety of audio capabilities
The BVP-900/900P has two microphone channels, two
intercom channels, and one program audio channel.
You can set the microphone channel to line level (0
dBu) with the switch on the side panel, and monitor
the microphone or line channel with the intercom
headset. The two intercom channels can be connected
to either the producer line or engineer line by setting
the corresponding switches on the rear panel.
Self-diagnostics functions
The BVP-900/900P has self-diagnostics functions to
facilitate troubleshooting.
