Ikegami details & Specifications

What standard of performance should be expected from a broadcast television camera with the latest CCD technology? Ikegami, in its continuing search for the highest quality and reliability provides the answer in the HK-355A camera system. The HK-355A is Ikegami's latest high performance studio and field production camera with FIT CCD sensors. Superb image producing technology is to be found within this compact camera system, particularly with regard to the latest high sensitivity FIT CCDs free from vertical smear, six axis optical low pass filter to reduce aliasing (moire patterning), optical axis adjustment for the optical block, 3 channel detail correction and wide band triax system. These new features specifically for CCD sensors go hand in hand with Ikegami's well established television camera technology, with CPU controlled automatic setup and diagnostic maintenance systems, superb quality pictures, high reliability and user friendly operation. With its vast experience and know-how in the industry and dedication to providing high standards of performance for television broadcasting at reasonable cost, Ikegami now offers this exciting new broadcast camera.

Features:

Compact camera head

The HK-355A camera head has been designed specifically for CCD sensors and incorporates full facilities for the full range of applications. The aluminum alloy head is light and compact, yet easy to operate and maintain. A lower viewfinder positioning provides better viewing for camera operators.

High resolution and high S/N ratio

Using 2/3-inch FIT CCD's each with 450,000 pixels, the HK-355A features a horizontal resolution of 800 TV lines (Y ch), a vertical resolution of 400 TV lines, and a high S/N ratio of 62dB.

High sensitivity

By incorporating CCDs with microlens technology, the sensitivity is improved by one f stop -f8 at 2000 lux.

Easy maintenance

The HK-355A saves camera adjustment and maintenance time by eliminating the need for registration, geometry, and other time-consuming adjustments. The camera head employs mother board construction with plug in modules.

Newly developed LPF

A newly developed multi directional optical LPF is incorporated to suppress aliasing inherent in the CCD sampling process. It provides an excellent balance with high resolution and very low aliasing.

3-DTL

Vertical detail correction is incorporated in each of the three color channels to produce uniform resolution in all colors including those lacking a green component. A complete horizontal MIX DTL is also provided to suppress the DTL-induced moire.

SKIN DTL

The HK-355A has a Skin DTL system which permits the amount of detail, in skin color, to be controlled independent of other scene content. This function makes it possible to soften the facial complexion of the talent while keeping all other parts of the picture sharp and detailed.

Optical axis adjustment

The HK-355A 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

In addition to five preset electronic shutter speeds, a continuously variable electronic shutter is also provided with an extended range from 1/62 to 1/5000 sec.

Highlight compression

Highlight compression allows the camera to handle high scene contrasts.

Linear matrix

Incorporating a linear matrix circuit, the HK-355A has ideal colorimetry and obtains images with superior color fidelity from dark to highlight areas of the picture.

Color corrector

Since the hue and 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 ",sed, the color reproduction data stored in one preadjusted camera can be used as a reference to provide automatic color matching for other camera heads used in the same production. This facilitates the previously time consuming process of color matching.

Auto level setup

Four auto level set up programs have been incorporated. The automatics align the video processing functions, with registration and geometry functions eliminated by virtue of CCD technology. Programs include Daily level and Full level set up, in addition to Auto White Balance and Auto Black Balance. The Daily level program automatically sets up the camera in less than one minute.

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 flexibility to the cameraman.

Adaptation to various cables (BS-323A Base Station)

Three types of cables, triax, multi, and fiber optic, can be selectively used by merely replacing a module, so that a suitable cable can be selected for particular applications. Especially, the triax cable permits wide- band signal transmission, thus ensuring high- resolution video at the base station side. Maximum extendable distance:

Triax cable; 14.5mm dia.............. 1800m

Triax cable; 13.2mm dia. (1/2 in.).. 1500m

Fiber optic cable; G2 80/125......... 3000m

Multiconductor cable: TV24........... 600m

HK-355PA Lightweight Companion

A lightweight version of the camera head for the HK-355A system is the HK-355PA. This lightweight, portable camera offers highly flexible system operation, either by using the same Base stations, OCPs, MCP or CCPs as the HK-355A, or by working as a self-contained independent unit with stand alone camera adapter, or even as a cameral recorder with an on-board video recorder. In order to increase its versatility, various accessories such as promptor (QTV) adapter, large lens supporter and larger viewfinders are available. Like its studio counterpart, the HK-355PA includes dual motor driven filter wheels, extensive remote control, full auto setup, and self-d-iagnostics.

Wide Choice of Control Panels

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 in-depth setup and diagnostic 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 data can be maintained. The CCP (Camera Control Panel) is designed to operate in conjunction with one camera and serves the dual purpose of maintenance and camera operation control. OCP (Operation Control Panel) serves the single OCP purpose of camera operation control.
