1-1. Overview
The BVP-900 full-size studio model color video camera and its
companion portable version, the BVP-950, are the flagship models of
the Sony CCD camera system. Developed for both studio and outside
broadcasting applications, this camera system is based on several
independent units, each of which has its own unique function. They
include pickup devices, camera heads, camera control units, a video
selector, master set-up units and remote control panels. With the
appropriate choice of units a wide variety of systems can be
implemented - from a single stand-alone camera to installations using
a total of 96 studio and portable models.
(Note: the BVP-900 and BVP-950 are for operation on 525 lines, 60
fields using the NTSC color standard. The BVP-900P and BVP-950P
versions are for operation on 625 lines, 50 fields using the PAL color
standard.)
1-2. Advanced Digital Signal Processing (ADSP) using 12-
bit A/D Conversion
Easy set-up and high reliability: With digital processing,
parameters are held in a digital memor y and stay constant for long
periods of time. As a result the need for operator adjustment is
dramatically reduced.
A further advantage of using digital processing is that it is much
easier to implement this circuitr y in ICs and LSIs, achieving benefits
in reliability.
Precise adjustment: The value of camera set-up parameters can be
defined with great precision by digital processing. Moreover,
variations between cameras, which are ver y difficult to avoid in
analog models, can be reduced to a minimum with digital processing
by simply equalizing parameter values.
Flexible signal processing and parameter setting: A significant
advantage of digital processing is that it can provide ver y flexible
operation. Many camera parameters can be controlled and each
parameter setting can be varied over a wide range of values.
1-3. Sony Design Criteria for Advanced Digital Signal
Processing (ADSP) Cameras
DSP cameras have tremendous potential to provide outstanding
improvements in camera operational efficiency. So when considering
the basic design concepts of its new DSP cameras, Sony laid down
the following design criteria.
* The BVP-900 Series must provide higher picture quality than
conventional 10-bit digital cameras. Operationally, it must be
compatible with previous Sony cameras.
* Digital system architecture should be consistent with current 10-
bit digital cameras so that both types can be mixed together
without picture matching difficulties.
* Camera peripherals should have a consistent design approach.
* To take full advantage of 12-bit digitization, as many camera
processes as possible should be digital; particularly gamma,
detail and so on.
Sony has taken these design criteria ver y seriously, introducing 12bit ADSP cameras with unprecedented perfor mance and r eliability,
and which are largely immune to physical factors such as
temperature changes and time.
1-4. Features of the BVP-900/900P
Easy-to-change CCD unit: The CCD unit is a separate block from
the camera head, so changing the aspect ratio from 16:9 and 4:3 and
vice versa is simply a matter of exchanging units. No readjustments
are required after the change under normal operating conditions.
The 1038H (NTSC/PAL) FIT Power HAD™ 1000 CCD Imager is
incorporated in the BVP-900/900P. (refer to Section 3)
Easy-to-operate design: The body design inherits the features of
previous generations of Sony cameras. A lower viewfinder position
decreases parallax between 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.
High picture quality: A newly developed 12-bit/36 MHz videoprocessing VLSI for broadcasting cameras assures the high quality of
pictures required for a studio-use CCD camera. (refer to Section 4)
High signal-to-noise ratio: A high signal-to-noise ratio of 65 dB
(NTSC)/63 dB (PAL) has been achieved as a result of the use of a
top-perfor ming Power HAD CCD, a new video-processing VLSI and
12-bit A/D converter.
Wide dynamic range: Automatic and manual control of knee point
and knee slope enables the clear reproduction of high-luminance
subjects at up to 600 % of nominal exposure level.
High sensitivity: A sensitivity of F10.0 at 2000 lux with OHB750WSA/P, OHB-730WS/P and OHB-730/P (typical) is achieved. For
OHB-750A/P, F8.0 at 2000 lux (typical) is achieved. When the video
gain is raised by +18 dB, a video level of 100% is obtained with
minimum subject illumination of 5 lux. (OHB-750A/P: 7.5 lux)
High vertical resolution: The vertical resolution can be improved
to 450 lines for the BVP-900 (550 lines for the BVP-900P) by use of
the EVS (Enhanced Vertical Definition System) function. The Super
EVS function, available when a FIT CCD block is installed, enables
the vertical resolution to be adjusted to a desir ed value between 400
and 450 lines for the BVP-900 (with an OHB-750A/750WSA CCD
Unit installed) or between 480 and 530 lines for the BVP-900P (with
an OHB-750AP/750WSAP CCD Unit installed).
High horizontal luminance resolution: 900 TV lines is achieved
with an OHB-750A/P or OHB-730/P CCD Unit installed.
Imperceptible vertical smear level: -145 dB by using the well
proven Power HAD 1000 CCD (FIT), with additional technology
enhancements.
Very high depth of modulation: 80% at 5 MHz is achieved.
Automatic set-up and filing function: Built-in microcomputers
give quick and precise automatic set-up, and also reduce the time
required for maintenance. The adjusted data can be stored in the
camera filing system.
Electronic shutter: An electronic six-speed shutter (from 1/60 or
1/100 second to 1/2000 second) is provided with the BVP-900/900P.
A rapidly moving object can be clearly shot by selecting the optimum
shutter speed. The shutter also has an ECS (Extended Clear Scan)
function. Using this function, the shutter speed of the BVP-900 can
be adjusted in 510 steps (from 1/30 to 1/58.3 and from 1/60 to
1/7000 second), and that of the BVP-900P in 607 steps (from 1/25 to
1/48.7 and from 1/50 to 1/9000 second). Appropriate shutter-speed

selection with use of the ECS function minimizes horizontal streaking
when shooting computer display screens.
Dynamic shading compensation function: When the zoom angle
is changed with the iris aperture almost completely open, modulation
shading can appear. The BVP-900/900P can automatically
compensate for this phenomenon to obtain optimum picture quality
at any zoom position. (This function is activated only when a lens
allowing this function is attached.)
Full range of audio features: The BVP-900/900P has two
microphone channels and one program audio channel. A switch on
the camera side panel changes the microphone inputs to accept line
level (-20 dBu) signals. Production and Engineering intercom, and a
program audio channel, are provided.
Self-diagnostic functions: The BVP-900/900P has self-diagnostics
functions to facilitate troubleshooting.
Display capability: Characters from a built-in character generator
are used by the BVP-900/900P to display zoom position, focus
position, the camera set up status and warning messages on the
viewfinder screen. A box cursor, center marker, safety zone and
zoom position are also displayed on the viewfinder screen. (refer to
Section 2)
Optional high-resolution 7-inch viewfinders: An optional 7-inch
black-and-white viewfinder (BVF-77/77CE) or 7-inch color viewfinder
(BVF-7700/7700P) can be used with the BVP-900/900P. For easy-tosee operation, the viewfinder angle can easily be changed and fixed
in the desired position. Attaching and detaching the viewfinder does
not require any tools. (refer to Section 2)
Picture-in-picture capability: The camera picture and the return
video picture can be checked simultaneously. With BVF-7700/7700P,
both the camera picture and the return video picture can be
displayed in color.
High-picture-quality return video: Monitoring a high-quality
return video picture on a or color viewfinder is possible because of a
3-line adaptive comb filter. (Monitoring on B/W viewfinder is also
enabled.)
Reliable transmission using triax cable: The BVP-900/900P
supplies wideband component video signals (Y, R-Y and B-Y) to a
CCU-700A/700AP Camera Control Unit via a triax cable with high
transmission reliability. The triax cable simultaneously transmits
power, video, audio and control signals between the BVP-900/900P
and the CCU-700A/700AP. Higher resolution and picture quality are
achieved with this wide bandwidth. (refer to Section 7)
Compact, lightweight and power-saving design: The BVP900/900P is a compact, lightweight design with low-power
consumption. These are fundamental requirements for outside
broadcast operation.
Precise, flexible and easy picture adjustment: In addition to
conventional camera adjustments, the BVP-900/900P features many
new control items. (refer to Section 5)
1-5. Features of the BVP-950/950P
Easy-to-change CCD unit: The CCD unit is a separate block from
the camera head so that the aspect ratio can be easily changed
between 16:3 and 4:3 simply by replacing the unit. No readjustment
is required after the change under normal operating conditions.
Newly developed LSI: A newly developed digital signal processing
LSI and a 12-bit A/D converter provide compr ehensive control
functions and assure a high-quality picture.
High signal-to-noise ratio: A high signal-to-noise ratio has been
achieved by use of a top-perfor ming Power HAD 1000 CCD,
outstanding circuit design and electronic packaging technology.
Wide dynamic range: Automatic and manual controls of knee point
and knee slope enable high-luminance subjects to be reproduced in
up to 600% of normal light.
High sensitivity: : A sensitivity of F10.0 at 2000 lux (typical) is
achieved with OHB-750WSA/P, OHB-730WS/P and OHB-730/P. For
OHB-750A/P, F8.0 at 2000 lux (typical) is achieved. When the video
gain is raised by +18 dB, a video level of 100% is obtained with
minimum subject illumination of 5 lux.
High vertical resolution: The vertical resolution can be improved
to 450 lines for the BVP-950 or to 550 lines for the BVP-950P by use
of the EVS (Enhanced Vertical Definition System) function. The
Super EVS function, available when a FIT CCD block is installed,
enables the vertical resolution to be adjusted to a desir ed value
between 350 and 450 lines for the BVP-950 (with an OHB750A/750WSA CCD Unit installed) or between 450 and 550 lines for
the BVP-950P (with an OHB-750AP/750WSAP CCD Unit installed).

camera using a filing function.
Electronic shutter: An electronic six-speed shutter (from 1/60 or
1/100 second to 1/2000 second) is provided with the BVP-950/950P.
A rapidly moving object can be clearly shot by selecting the optimum
shutter speed. The shutter also has an ECS (Extended Clear Scan)
function. Using this function, the shutter speed of the BVP-950 can
be adjusted in 510 steps (from 1/30 to 1/58.3 and from 1/60 to
1/7000 second), and that of the BVP-950P in 607 steps (from 1/25 to
1/48.7 and from 1/50 to 1/9000 second). Appropriate shutter-speed
selection with use of the ECS function minimizes horizontal streaking
when shooting computer display screens.
Self-diagnostic functions: The BVP-950/950P has self-diagnostic
functions to facilitate troubleshooting.
Display capability: Characters from a built-in character generator
are used by the BVP-950/950P to display zoom position, focus
position, the camera set up status and warning messages on the
viewfinder screen. A center marker and safety zone are also
displayed on the viewfinder screen. (refer to Section 2)

2-1. System Configuration
The BVP-900 Series is based on the renowned BVP-700 Series and
DSP technology pioneered by Sony in the earlier BVP-500 Series
camera system. This new system features two camera heads, the
BVP-900/900P full-size studio model and a full companion portable
camera, the BVP-950/950P. This por table model is designed for full
integration into a BVP-900/900P studio camera system, as well as
being used as a standalone acquisition camera in combination with
Betacam VTRs. Figure 2-2 shows how this interface is pr ovided by
the CA-553 50-pin Camera Adaptor. A variety of key peripherals, such
as the CNU-700 and CNU-500 Camera Command Network Units help
users to easily expand/upgrade their system. These peripherals
provide a perfect interface with the growing ranges of Sony digital
component equipment, such as Betacam SX and Digital BETACAM
products.

2-4. Control System
(Please refer to section 6. Control System for fur ther infor mation)
In addition to the MSU-700 Master Set-up Unit and eight different
types of RCP-700 Series Remote Control Panels, the CNU-700 and
CNU-500 Camera Command Network Units form the command
ner ve center for a new concept in camera control system. A wide
selection of control peripherals allow each user to configure the most
suitable system to meet a specific operational need. The following are
the key peripherals.
(a) Master Set-up Unit (MSU-700)
The MSU-700 Master Set-up Unit can control up to 6 cameras (up to
12 cameras by using an expansion board) in combination with the
CNU-700 Camera Command Network Unit. The adoption of an EL
Touch Panel in the MSU-700 helps to simplify the operation of its
sophisticated control system. And data such as scene files can be
stored in a world-standard PC memory card.
(b) Camera Command Network Units (CNU-700 and CNU-500)
The Camera Command Network Units are designed to be the ner ve
center of the Sony camera control system for the BVP-900 Series,
BVP-700 Series, BVP-500 Series and HDC-700 Series of cameras.
They work as ‘Command Selector’, ‘Command Distributor’ and
‘Command Arbitrator’. These two types of camera command network
units give a cost/perfor mance choice. The CNU-500 is suitable for
applications with up to six cameras, while the standard six cameras
capability of the CNU-700 can be expanded to 12 cameras with use of
the BKP-7930 optional expansion board. With the BKP-7932 optional
command conversion board installed instead of the BKP-7930, the
CNU-700 can operate with six previous-generation CCU-370/355/350
units as well as six CCU-700A/550 units.
The carefully designed software and the high-speed CPU of both the
CNU-700 and CNU-500 give them a fast response time whatever the
system configuration.
(c) Video Selector (VCS-700)
The VCS-700 Video Selector is used to switch composite video
monitoring signals from a BVP-900 Series multi-camera system to a
picture monitor and waveform monitor. The VCS-700 accepts the
video monitoring signal from up to six CCU-700A or CCU-550
Camera Control Units and switches these signals to two picture
monitor outputs and two waveform monitor outputs. The selection of
monitoring signals can be controlled by the camera selection buttons
on the MSU-700 Master Set-up Unit, or by external control
equipment through the D-sub 37-pin I/O port on the VCS-700.
For SDI monitoring, the optional BKP-7933 S-Bus Interface Board
provides connection to a Sony digital routing system.
(d) Remote Control Panels (RCP-700 Series)
There are four ranges of Remote Control Panel for the BVP-900
Series. Each range has two types - joystick control and dial control.
The RCP-740/741 is the top of the range for sophisticated operational
use, and can be used as a substitute for the MSU-700 Master Set-up
Unit in some special applications. The RCP-730/731 is the mid-range
model with general control function, especially useful for limited
space with its slim design. The RCP-720/721 is also a mid-range unit,
with sufficient control functions for general use. Finally, the RCP700/701 features the basic control items required for daily operation
of acquisition camera systems. The RCP-730/731, RCP-720/721 and
RCP-700/701 can all be used as a sub-control panel to support an
MSU-700 or RCP-740/741.
2-5. Viewfinders
As well as the BVF-77/77CE, a high perfor mance 7-inch
monochrome viewfinder with extremely high horizontal resolution,
the BVF-7700/7700P 7-inch high grade color viewfinder is also
available for the BVP-900/900P. This high grade color viewfinder is
especially convenient for cases where color needs to be identified by
the camera operator. For the BVP-950/950P, a 5-inch monochrome
viewfinder, the BVF-55/55CE, is available. All of these models are
ver y compact in size, light in weight and economical in power
consumption. The low mounting positions of the BVF-77 and BVF7700 Series provide convenient viewfinder displays aligned as close
as possible to the lens axis.

3-1. Industry-first Plug-in Imager Assembly
The Plug-in Imager Assembly is in the form of a self-contained
imaging subsystem. It is, in essence, a miniature plug-in camera
containing the CCD block and all its support systems. This imager
assembly can be easily removed and installed so that operators with
no special skills can easily exchange imager assemblies in the field.
There are several types of Imager Assembly. The OHB-750A/750AP
is a 2/3-inch 4:3 FIT type CCD and the 750WSA/750WSAP is a 2/3inch 16:9/4:3 switchable widescreen FIT type CCD. For IT types, 4:3
standard screen sized OHB-730/730P and 16:9/4:3 switchable
widescreen OHB-730WS/730WSP are available. The latest Power
HAD technology achieves superior S/N ratio and extremely low
smear level. One ver y beneficial feature is that no readjustment is
required after exchanging these imager assemblies. This
breakthrough concept also of fers a highly cost-effective way of
upgrading CCDs over the camera life span.

SONY ADVANCED ELECTRONIC IMAGING TECHNOLOGIES
imager technology with a sustained, broad-ranging research and
development program. The benefits of this technological
commitment can be seen in the wide range of Sony CCD cameras from mass produced types for consumer use to professional cameras
for field and studio operations. The top end of this range has now
been further expanded with the introduction of the Power HAD 1000
16:9/4:3 switchable widescreen CCD sensors for the BVP-900 Series.
Total picture performance is a complex function of many attributes in
imager y. Improvements in overall camera picture quality are a result
of continuing developments of the CCD imager, the CCD support
circuitr y and video processing. As the CCD imager itself r emains
central to the direction of recent camera development, enhancements
to the total perfor mance of CCDs for broadcasting cameras ar e of
critical importance. For this purpose, Sony developed the Power
HAD 1000 and has continuously been refining it ever since.
3-3. Power HAD 1000 CCD
The Power HAD 1000 CCD has 1038 horizontal picture elements, a
total of 520,000 for NTSC and 620,000 for PAL. Introduced with the
previous generation of cameras, the BVP-500 Series, Sony improved
the Hyper HAD 1000 CCD to complement 10-bit DSP. For the new
‘top of the line’ BVP-900 Series, Sony has developed a totally new and
outstanding design of CCD imager to complement its 12-bit ADSP for
the following reasons.
High picture quality
With its extremely high pixel count, the Power HAD 1000 provides a
horizontal resolution of over 900 lines, a high depth of modulation of
80% and minimum aliasing. Sony advanced semiconductor
technologies also give the Power HAD 1000 high sensitivity and ver y
low smear - despite its large number of picture elements. With the
inherent high level of picture quality provided by this imager, the
precise picture adjustment capability of digital cameras becomes
even more important.
Excellent matching of CCD and camera to digital environment
The Power HAD 1000 has not just been developed to provide
excellent picture quality. When developing a CCD for digital cameras,
the relationships between CCD drive clock frequency, digital signal
processing sampling rate and the digital VTR sampling rate have to
be considered. Simple relationships between these three parameters
result in easy signal conversion from CCD output to digital video
signal, in turn reducing the complexity of the digital LSIs and
reducing camera power consumption. The 18 MHz clock frequency
of the Power HAD 1000 was chosen to fulfill this requirement. It has
a direct relationship to the 18 MHz and 36 MHz sampling rates in the
camera and a simple, 4/3 relationship, to the 13.5 MHz sampling
frequency of the Digital BETACAM™ format.
3-4. High Depth of Modulation
The high packing density achieves an excellent depth of modulation
perfor mance of 80 % at 5 MHz.
3-5. Minimum Aliasing with New Optical Low-Pass Filter
Incorporating the Power HAD 1000 in the BVP-900 Series involves an
extremely high sampling rate of 18 MHz. This high clocking rate, in
combination with precision CCD spatial offset and the exclusive
design of the new optical low-pass pre-filter, reduces aliasing to a
level never achieved in previous generations of CCD cameras.
3-6. High Sensitivity
The power HAD 1000 CCD imager inherits the OCL (On-Chip-Lens)
technology used in all other Sony broadcast-range cameras. The OCL
layer of the CCD chip effectively concentrates the incident light on

the photo sensor area by precisely positioning a microlens over each
pixel. As a result, the camera sensitivity is doubled, achieving a
figure of F10.0 at 2000 lux with OHB-750WSA/P, OHB-730WS/P and
OHB-730/P. (F8.0 with OHB-750A/P.) The following Figure 3-5
shows how the OCL enhances sensitivity.
3-7. Invisible Smear Level
The OCL layer in the Power HAD imager effectively concentrates the
incoming light on the photo sensor so that leakage of light is greatly
reduced. The direct result of this is a very low smear level (even on
the IT sensors). This further improvement of the masking
techniques in the Power HAD 1000 (FIT) has reduced the smear to a
level of -145 dB (FIT), which is invisible. The following Figure 3-4
and 3-5 shows the new techniques.
3-8. Excellent Signal-to-Noise Ratio
The superior structure of the Power HAD imager greatly contributes
to a reduction in the dark current noise to 1/10 of that in the
previous generation of CCDs. This gives a corresponding r eduction
in the fixed pattern noise, maintaining low noise characteristics in all
imaging situations. In combination with an advanced CCD support
system, the Power HAD 1000 incorporated in the BVP-900 Series
achieves the excellent signal-to-noise ratio of 65 dB (typical) for
NTSC and 63 dB (typical) for PAL.
3-9. Super EVS (Enhanced Vertical Definition System)
The basic Enhanced Vertical Definition System (EVS) can sometimes
cause line flicker due to the increase in vertical definition. Super
EVS, which is available on BVP-900 Series cameras fitted with FIT
sensors, allows the vertical resolution to be enhanced over a range of
400 to 450 lines for NTSC and from 450 to 530 lines for PAL This is
achieved by changing the charge mixing ratio in the CCD read out.
This function is remotely controlled from the MSU-700 Master Set-up
Unit and permits the balance between ver tical resolution and motion
blur to be optimized for different scene contents, while keeping line
flicker to a minimum.
3-10. Clear Scan and ECS (Extended Clear Scan)
The well proven Clear Scan and ECS functions eliminate banding
effects when shooting monitor displays by allowing the shutter speed
to be adjusted so that it exactly matches the various scanning
frequencies that are in use. For FIT CCDs, the Clear Scan shutter
speed range is 60.1 to 7000 Hz for NTSC and 50.2 to 9000 Hz for
PAL, the ECS range is 30.4 to 58.3 Hz for NTSC and 25.4 to 48.5 Hz
for PAL. For IT CCDs it is 60.1 to 7000 Hz for NTSC and 50.2 to 9000
Hz for PAL. The ECS function is especially effective for shooting
computer displays that have vertical scanning rates below 60 Hz.

Spatial Offset Technology to provide higher resolution. The image
captured on the photosensors of each CCD is read out at a clock
frequency of 18 MHz.
4-3. Analog Signal Processing Domain
Gain boost process is perfor med in the analog domain by a Video
Amplifier circuit. After that white balance and pre-knee are processed
with an AD board. The video signal from the CCD, which can have a
dynamic range of 600% of nominal white level, is compressed to
approximately 340% by this pre-knee process and conver ted to a 12bit digital signal at an 18 MHz sampling rate. This is the same
sampling frequency as that of the Power HAD 1000 imager.
4-4. Digital Signal Processing Domain
The camera signal processing is executed in the digital domain in
BVP-900 Series cameras. Within this digital processing, more than 12
bits are used in critical applications such as shading compensation,
image enhancing and gamma correction.
As shown in the diagram, three VLSIs are used for processing. In the
SH VLSI, the peak and average levels are measured, together with
other parameter of the video signal. These measurements are sent to
the analog circuits as feedback signals. The PR circuit contains the
main camera processing; gamma controls, knee slope controls and so
on. The RC circuit is used for aspect ratio conversion between 16:9
and 4:3. The ARC is a separate board supplied with widescreen,
switchable, OHB CCDs. The SH, IE, PR and ARC are using the latest
VLSI technologies.

5-1. Full DSP Camera Processing
The BVP-900 Series uses 12-bit A/D conversion based on the latest
LSI technology. This advanced technology has allowed Sony to take a
major step for ward fr om the 10-bit conversion of its previous
generation of cameras – a move that was not possible with earlier
A/D converters and DSP LSIs.
(a) Multi Matrix
Multi Matrix is a function that electrically adjusts the basic RGB
color ‘taking characteristics’ of the camera to achieve optimum
colorlimetr y. It makes it easy to match the color of cameras under
multi-camera operations, or to reproduce the characteristics of
another type of camera. It can also be used to manipulate color for a
particular special effect. A conventional linear matrix function
provides only six adjustable parameters, with considerable
interaction between their effect on a specific color. Multi Matrix
divides the spectrum into 16 segments, each of 22.5 degrees, for
each of which there is an independent hue and saturation parameter.
Multi Matrix allows the selection of each of these segments, with
separate adjustment of hue and saturation parameters. Operation
flow is as follows:
1) Select Multi Matrix on the paint menu of the MSU-700 Master
Set-up Unit.
2) Tur n the Matrix and the Multi switches to ON.
3) The MSU-700 EL display now shows a representation of the
Multi Matrix as it would appear on a vectorscope. You can
select the desired color phase that you want to adjust.
4) After selection of the color phase, its hue and saturation can
be adjusted.

(b) Auto Knee
When the Auto Knee button on the MSU or RCP panel is pressed, it
optimizes the knee point and knee slope for best reproduction of the
high lights. The Adaptive Highlight control function can also be used
in conjunction with Auto Knee.
(c) Gamma
New 12-bit A/D conversion defines more precisely the required
gamma characteristic by using a gamma cur ve created from 48
segments. This is in comparison with the 32 segments in the
previous camera range.
(d) Black Gamma
Black Gamma allows control of the linear part of the gamma
characteristic, providing adjustment of the shadow areas of the
picture during shooting.
(e) Black Clip
Improvements in the Black Clip circuitr y have impr oved the
signal/noise ratio for more natural reproduction.

5-2. Precise Handling of Highlight Position
(a) Optimized bit assignment
The video level up to 260% is processed linearly. Highlights over 260%
are compressed by a pre-knee circuit before A/D conversion,
providing the most efficient utilization of the 12-bit A/D conversion
process.
(b) Knee Saturation
Knee Saturation eliminates both the ‘washed out’ effect and hue
changes in overexposed areas of a picture, providing more natural
color reproduction.
(c) Adaptive highlight control (Auto Knee mode)
Conventional cameras only have a single knee point/slope
characteristic. In contrast, the Sony ADSP system has multiple knee
point/slope characteristics. The camera intelligently monitors the
brightness of all areas of the picture and adapts the knee point/slope
for optimum reproduction. A typical example is shooting an interior
scene which includes a sunlit exterior seen through a window. This
new function applies only to video levels in excess of the knee point,
the middle and low luminance parts remaining unchanged.

are not limited to skin tones, but can be set for any color. Detail may
be increased or decreased relative to the normal level.

This function is similar to an optical soft filter. By subtracting the
edge enhancement signal from the original video signal, slight

new creative feature that can be used to either complement or
replace the Skin Tone Detail Correction function, when more of a
‘film look’ is sought for close-ups, etc.

(g) Skin Tone Auto Iris
A problem with conventional auto iris is that movements of bright
objects in a scene adversely affects facial exposure – a news studio is
a typical example. Skin Tone Auto Iris is a function that controls the
auto iris system to ensure a constant video level for a defined human
skin area within the scene. In the news studio example, when the
color phase is adjusted to match the facial tones of the news reader,
the iris now maintains the same video level even if the reader turns
the script, or people enter or exit the scene. It is effective for the
other colors in addition to human skin tone.
(h) 3-D White Shading Correction
The camera picture area is divided into up to 1000 separate zones,
each of which may have different shading value. The correction is
automatically interpolated across adjacent zones. This technique
provides precise white shading correction over the whole pictur e
area. The 3D shading mode can be enabled through the camera
maintenance menu, and operates automatically each time white
shading is perfor med. Because the camera ‘learns’ and interpolates
the data the accuracy may be improved still further on subsequent
auto shading operations. White shading data should be stored in the
camera OHB file or will other wise be lost when the camera power is
turned off.

5-3. Outstanding reliability and easy maintenance
One of the most important concerns for broadcasters is the reliability
of equipment. This is considerably improved with Sony digital
processing. In Sony ADSP cameras all the processing parameters are
completely and precisely defined at the design stage, and almost all
the potentiometers are replaced by semiconductor memories.
Consequently, Sony ADSP cameras show extremely stable
perfor mance, regar dless of environmental conditions such as
temperature, humidity, shock and vibration. This high stability,
together with the advantages of the self-contained menu system,
enables the accurate set-up of camera systems easily for regular
realignment to maintain. Finally, a great merit of Sony ADSP cameras
is their advanced self-diagnostic system. BVP-900 Series cameras
detect problems in their digital processing and provide viewfinder
warning indication. Detailed information, such as identifying the
faulty board, is also shown on the Master Set-up Unit screen and the
Camera Command Network Unit character display to provide easy
and rapid fault location.
5-4. Low power consumption
To achieve its design aim of complete digital processing, including
digital implementation of the non-linear processing stages, Sony has
developed VLSIs which contain over 1,600,000 actual gates. This
complexity demonstrates the advances that Sony has made in the
application of its semiconductor technology. Despite this complexity,
Sony ADSP cameras approach the same low power consumption as
previous analog portable cameras. This has been made possible by
using the Sony EDA (Electronic Design Automation) system to
optimize the complex camera circuitr y in a short time scale and to
incorporate the latest LSI technologies (2.5 V drive and 0.35 µm
design rule) to give a total power consumption of just 20 W for the
BVP-950/950P portable camera with an OHB-730 CCD block
installed.
