HK-355 / HK-355P CCD Studio/Field Camera Features
HK-355 / HK-355P
CCD Studio/Field Camera
Ikegami's new HK-355 CCD Studio / Field
Camera takes full advantage of CCD
technology. Incorporating state-of-the-art
circuit design, the HK-355 Camera System
will find widespread use in both studio and
field applications. The HK-355 performance
characteristics are comparable to 30mm
tube cameras in teJ'JJls of image quality
and functions. A variety of new features,
such as a 6-order optical LPF and an optical
axis alignment mechanism are incorporated
so that CCD features are utilized to
maximum advantage. These features and
video circuit technology that derive all a
450,000 pixel CCD has to offer work
together to ensure a high level of
performance: 800 lines of horizontal
resolution; an S/N ratio of 62dB or more,
and a registration error of 0.02%, or less. In
addition, the new CCD driving system, and
the 3-DTL enhancer incorporated in the HK355 give improved vertical resolution and
dramatically reduce moire noise patterns.
This camera system accommodates various
types of cables, such as triaxal,
multiconductor and fiber optics, and oHers a
host of salient features that permit flexible
and versatile operations. The HK-355 CCD
meets all the requirements of a studio / field
camera.

Well balanced camera head
The camera head, made of aluminium,
provides proper balance and increased
maneuverability.
High resolution and high S/N ratio
Using 213-inch FIT CCD's with 450,000
pixels, the HK-355 features a horizontal
resolution of 800 TV lines (V ch) , a vertical
HK-355P
resolution of 400 TV lines, and a high SIN
with
TA-355
Triax Adapter
ratio of 62dB.
Easy maintenance
The HK-355 saves camera adjustment and maintenance time by
eliminating the need for registration, geometry, and other time-consuming
adjustments. The camera head also employs mother board construction
within modules.
Newly developed LPF
A high-sensitivity prism is employed. A newly developed six-directional
optical LPF is incorporated to suppress false signals inherent in the CCD
sampling process. The resolution rivals 30mm tube cameras.
3-DTL
Three-channel vertical detail correction is incorporated and provides for
color objects lacking the green component. A complete MIX DTL is also
provided to suppress the DTL- induced moire.

Optical axis adjustment
The HK-355 has a newly-developed feature that allows adjustment of the
optical axis of the prism block, so that the center of the lens and the CCD
are correctly aligned. This function gives full correction of optical axis,
especially when a lens with high magnification is used .
Electronic shutter
The continuously variable electronic shutter is provided for the range of
1/60-5000 sec.
Highlight compression
Highlight compression allows the camera to handle high scene contrasts.
Linear matrix
Incorporating a linear matrix circuit, the HK-355 has ideal color analysis
and obtains images with superior color fidelity from dark to highlight areas
of the picture.
Color corrector
Since the hue nad saturation can be controlled separately for each of the
R, G, B, C, M, and y color vectors, tones can be finely tuned in greater
detail.
Auto color corrector
When multiple cameras are to be use<4; the color reproduction data
stored in one preadjusted camera can be used as a reference to provide
automatic color matching for other camera heads in synchronized
operation. This facilitates the previously timeconsuming process of color
matching.
Auto level setup
Auto level setup functions have been incorporated. With chip technology,
the registration and geometry setup func- tions normally associated with
tube-type cameras have been eliminated. The camera head can be used
alone as a self-contained unit. Camera cables -triax, multicore, and fiber
optic, can be changed simply by changing modules. Various control
panels such as, OCP, CCP, and MCP can be connected to the base
station or camera head to perform versatile operations for each particular
application . Since the HK-355 system configuration is the same as the
HK-323, the base station and other peripheral equipment are common to
both camera systems.
The HK-355P portable camera, may be connected to the same type of
base station, but may also be used as a stand- alone or with an on board
VTR. Furthermore this camera can be used with full build-up kit for long
focal length lens operation. (System Diagram)
Self-diagnosis system
In the event of camera head or base station trouble the self- diagnosis
system alerts the operator, prompting him to take corrective action.

7-inch viewfinder
This camera comes equipped with a 7 -inch viewfinder as a standard
accessory. A host of indications are displayed on the viewfinder to
provide ease of use and operational flexi- bility to the cameraman.

Adaptation to various cables
Three types of cables, triaxial, multiconductor, and fiber glass, can be
selectively used by merely replacing a module, so that a suitable cable
can be selected for particulqr applica- tions. Especially, the triaxial cable
permits wide-band signal transmission, thus ensuring high-resolution
video on the base station side . Maximum extendable distance:
• Triaxal cable: Fujikura (8.5mm dia.) : 800m
• Triaxal cable: Fujikura (14.5mm dia.) : 1600m
• Fiber glass cable: Fujikura G2 80/125 : 3000m
• Multiconductor cable: 28-conductor: 600m
A variety of control panels can be connected to the base station to
accommodate different styles of operation. The MCP (Maintenance
Control Panel) is dedicated to maintenance purposes. When used in
conjunction with the CSU (Camera Select Unit) , up to 40 cameras are at
the beck and call of a single MCP. By the use of the RS-232C interface,
camera conditions can be printed out so that easy and exact control of
date can be maintained. The CCP (Camera Control Panel) is designed to
operate in conjunction with one camera and serves the double purpose of
maintenance and camera operation control. OCP (Operation Control
Panel) serves the single purpose of camera operation control.
