AJ-PD900W combines a color video camera, which features a 520,000-pixel
high-sensitivity M-FIT 3-CCD configuration and an on-chip lens, with a DVCPRO
format VTR which in turn features the latest compression technology in a single
addition to the existing interlace signals (525i), progressive signals (525P)
can also be recorded. Either 16:9 or 4:3 can be selected as the screen aspect
ratio, and the rate at which the signals are recorded onto the VTR tape can be
set to 50 Mbps for a higher picture quality or 25 Mbps for longer recording
duration. (Six recording modes are available for selection.) The AJ-PD900W is
compact and light weight with low power consumption, and realizes the optimal
functions and performance for an electronic news gathering (ENG) VTR-integrated
camera such as high picture quality and sensitivity, mobility, dustproofing and
dampproofing, etc. In addition, both the camera section and the VTR employ a
digital signal processing system which
improves picture quality and realizes a system for controlling setting menu and
subject data by using world standard memory cards.
Features of the Camera Section
The camera section
of the AJ-PD900W has the following features.
sensitivity: 2000 lux (F8)
S/N ratio: 60 dB
Signal processing is
digitized by a 36 MHz (typ.) 10-bit AD/DA converter. This improves picture
quality, stability and reliability, and allows the viewfinder screen displays as
well as numerous adjustment and setup items to be converted to menus.
The setting menu is
displayed on the viewfinder screen, and controls the status displays, messages,
marker displays, etc. Whether or not to display each item, as well as the
display conditions when items are to be displayed, can be selected according to
the user’s convenience. For example, display ON/OFF for the ! lamp display
which informs the user that the unit has entered irregular status can be
selected for 6 different conditions. The setting menu is also used to select
various settings and functions and execute memory card operations, etc.
Setting menu and
subject data can be stored on SRAM memory cards with a capacity of 64 kilobytes
or greater which conform to PCMCIA standard ratings as setup cards. Stored data
can be saved individually or according to the shooting conditions, allowing the
same setup conditions to be easily reproduced and assisting in standardizing
setup conditions between individual data.
Using the built-in
electronic shutter achieves steady images even of quickly moving subjects. In
addition, the following special operation modes can also be selected.
Synchro scan mode:
This mode is suited for shooting personal computer and workstation monitor
screens, and provides images with little horizontal stripe noise.
Wide range of video
Gain values can be
selected from p3 dB to o30 dB using the setting menu and the GAIN switch. The
high S/N ratio allows images with little noise to be obtained even when the gain
is increased for shooting in dark locations. Using the SUPER GAIN switch
provided specially to implement the super gain function, the video gain can be
set to 30 dB.
and memory functions for black balance/white balance
The black set, black
balance and white balance can be automatically adjusted by simple switch
operations. Adjustment values are held in the memory even if the power for the
unit is turned off, so there is no need to readjust the balance each time the
power is turned on. There are two memory systems for white balance which can
hold four adjustment values each for the CC and ND filters, making a total of
eight adjustment values. When adjustment values
illumination conditions are selected from among the values stored in the memory,
the unit is automatically adjusted to the corresponding white balance. (A menu
setting also allows adjustment of only two values instead of the values for each
filter.) In addition, when the unit is shipped from the factory, the white
balance value for 3200K is stored in the memory as a preset value. This value
can be called when there is no time to adjust the white balance, etc.
The unit is equipped
with a function that displays switch settings, the automatic adjustment status
for black balance and white balance, warning displays, etc. on the viewfinder
screen. In addition, when using an Anton Bauer Digital Magnum series battery as
the unit’s power supply, the remaining battery level can be displayed
numerically on the viewfinder screen.
Warning system for
displaying the VTR section status
The unit informs of
VTR trouble, the end of the tape, battery wear, etc. with various warning lamps
and a warning tone. The remaining tape time can also be checked by the character
display inside the viewfinder.
Four filter disks as
temperature conversion) and ND (neutral density) filters are provided as
standard equipment. This allows the optimal filter setting to be selected from
among four combinations in accordance with the brightness of the subject.
Fine adjustment of
the automatic iris reference value
The reference value
for automatic iris adjustment can be finely adjusted by setting menu operations.
Auto close function
The unit is equipped
with an auto close function which automatically closes the lens in the following
the black balance is automatically adjusted.
the power is turned off in the auto iris mode.
Generation of SMPTE/SNG
color bar and reference audio signals
The camera section
contains a circuit which generates an SMPTE type color bar signal to facilitate
color monitor adjustments, and a circuit which generates a reference level audio
signal to facilitate audio level adjustments. The unit also contains a circuit
for generating SNG color bar signals which come in handy for sending signals to
circuits for assuring high picture quality
The AJ-PD900W is
equipped with the following functions (and circuits) in order to assure high
picture quality and is designed to make the fullest use of the advantages of the
built-in AUTO KNEE circuit achieves a wide dynamic range which allows large
signals to pass through.

Recording by an
When an external VTR
is connected using the 26-pin/12-pin output adaptor (option, AJ-YA900P),
recording can be performed by the external VTR instead of the internal VTR.
Extension Control Unit (option, AQ-EC1) allows a portion of the camera section
functions to be operated by remote control.
of the VTR section
The VTR section
features a component digital recording system that employs the latest
compression technology and non-compressed PCM recording for audio. This system
provides superior S/N, frequency band and waveform characteristics as well as
reproduction of detailed areas,
etc., and realizes
even higher picture and sound quality. One of the following 6 modes can be
selected for conducting recording and playback: 16:9P
(50 Mbps), 4:3P (50
Mbps), 16:9i (50 Mbps), 4:3i (50 Mbps), 16:9i (25 Mbps), 4:3i (25 Mbps).
Rec review function
automatically rewinds the tape and plays back the last two seconds recorded,
allowing recorded contents to be quickly checked.
Playback pictures (black-and-white
pictures) can be seen on the viewfinder screen. In addition, color playback
pictures can be seen on a color monitor connected to the VIDEO OUT connector on
the main unit.
Built-in time code
information can be recorded and played back on a dedicated subcode track.
Locking of the
time code to an external source
The built-in time
code generator can be locked to an external generator. Also, the built-in time
code generator uses a lithium battery as its back-up power supply, allowing time
codes to be backed up for approximately one year even if power is not supplied
to the unit.
Built-in DOLBY NR
A Dolby B Noise
Reduction System is built in for audio recording in the longitudinal direction.
Images can be shot
successively within an accuracy of 0–o1 frame simply by pressing the VTR START
button or the lens VTR button.
