1. GENERAL
�-
The Hitachi FP-Z31/Z31 L is a 3-tube portable color camera employing 2/3-inch electromagnetic focusing/
electrostatic deflection (MS type) SATICON* tubes. It is designed to feature a high quality picture with
a horizontal resolution of 750 lines and a signal-to-noise ratio of 58 dB. Equipped with a wide range of
automatic functions, this is a high-quality camera for professional uses embodying superior cost perfor­
I'
f: mance. Featuring Automatic Beam Optimizer (ABO), auto iris and microcomputer-based auto white, auto
black, auto centering**, auto setup** functions etc., the camera has excellent operational ease and displays
sharp and clear pictures which can be pr' od uced even by non-skilled operatorsu.The camera comes with
{,
a wide range of accessories which open up a whole host of appl icaiions both as a portable camera with top-

( 1 )' High sensiti�ify.
A high-performance f 1.4 prism optics assures a
hi � h- level of sensitivity. The +9 dB or +18 dB high
�a(o function and the low-noise amplifier provide
sharp . and clear pictures under poor lighting
conditions.
( 2) High resolution and high signal-to-noise ratio
The adoption of Hitachi's newly developed electro-
magnetic focusing/electrostatic deflection type of
r.
, ,.._
pickup tube provides a high resolution evenly over
. __ _)
the entire picture from the center to the corners.
Furthermore, the new structure (LOC-Low Capaci­
tance type) adopted for the pickup tubes and the
low-noise amplifier
assembly contribute to the high signal-to-noise
ratio (horizontal resolution of 750 lines at center
and a typical 58 dB SN ratio for NTSC and 55 dB
for PAL).
( 3 ) Automatic beam optimizer
The built-in automatic beam optimizer reduces
comet-tailing and expands the dynamic range up
to approximately 8 times the rated light.

adjust the white balance and black balance auto-

adjusted values are retained for about two years
(typically) by the memory function even when the
camera's power is switched off.
GAIN
Once the AUTO/PRESET switch has been
set to the PRESET position, the white balance
is set to 3,200 K and so shooting can start immed­
iately without setting the.
when the camera operator"is in a hurry.
( 5 ) Auto iris, auto iris close functions
The self-contained auto iris circuit automatically
controls the lens iris and provides sharp and clear
pictures. NAM (Non-Additive mixing) and weight­
ing functions of iris control have been added to
this circuit for stable operation even with mono­
chromatic lighting or with the shooting of objects
against a bright sky in the background.
In order to safeguard the pickup tubes from any
kind of damage, the iris automatically closes while
the auto black . circuit is functioning when the
camera's OPE/STANDBY switch is at the STAND­
BY position and its BAR/CAM switch is at the
BAR position.
( 6) Auto centering (FP-231 only)
The centering is automatically adjusted by the
