Ikegami ITC-730A

The High Performance ENG / EFP Camera for Budget Conscious Professionals

Ikegami introduces the ITC-730A to the world and sets the standards for advanced, compact, high-performance and modestly priced handheld color cameras.

The same Ikegami know how that developed the world's top selling ENG camera has gone into making the ITC-730A a compact, professional, and economical camera capable of consistently producing quality pictures of fast-breaking events. The ITC-730A is the perfect answer for the cost-conscious TV station or cable operation that wants a multi-purpose, high-quality ENG/EFP camera that's easy to maintain.

The ITC-730A isn't simply a scaled-down product, but comes with features you won't find in any other ENG camera. Innovations like a revolutionary new way of accessing the optical block, which will cut down on the time and bruised fingers it takes to replace the pickup tubes. With the ITC730A in your camera operator's hands, you'll have a camera that not only works great, but looks great too - a camera that will say "professional" wherever you take it.

Look into the ITC-730A and see why it's the smart, economical, professional choice.

Performance Features

· Saticon®II pick-up tubes are utilized for lowest image lag.

· A built-in high-speed (£I 1.4) prism beamsplitter produces pictures with low shading, excellent resolution, colorimetry, and high sensitivity (£I 4.0 at 2000 lux).

· A high-performance FET is built into the coil assembly to offer pictures with an excellent signal-to-noise ratio of 57 dB. · Bias light is incorporated to reduce lag on low-light scenes. · A horizontal and vertical detail corrector assures an excellent, crisp, sharp image. (A 2H detail corrector with built-in comb filtering)

· The camera employs a deflection distortion corrector to make images with extremely low registration error.

· To ensure superior corner resolution, dynamic focus is employed.

Operational Features

· The light weight camera head is well balanced on the shoulder, so there is no feeling of fatigue during extended operation.

· Rugged camera head: The camera head is made from a tough, magnesium diecast alloy.

· The lens mount is the same size as that on the ITC-350, ITC-730, HL-79D and HL-79E cameras. Perfect interchange among lenses is possible - meaning you can use a wide variety of ENG-type high-magnification lenses with any of these cameras. · A servo type auto iris control system is capable of sensing peak video, average picture level (APL), or variable combination of peak and APL. An iris weighting system is also incorporated.

· The auto iris closes automatically to protect the camera pickup tubes from damage whenever the power is turned off.

Outdoors (sunny weather):56000K + 25 % ND

CAP: Blind

The + 9 dB/ + 18 dB video gain switch makes it possible for you to increase the sensitivity by up to 8 folds, enabling shooting under lighting conditions as low as 40 lux (with an £11.f/ 1.6 lens).

A built-in DBS (Dynamic Beam Stretch) discharges spectral highlights, which minimizes comet-tailing.

An easy-to-read zebra pattern indicator is displayed in the viewfinder to ensure optimum matching of video signal levels.

The split field color bar generator built in the encoder offers convenience in adjusting the monitor (meets RS-189A).

Return video can be viewed on the viewfinder.

Power consumption can be reduced by using the standby switch. (During standby: approx. 1 W)./

The eyepiece position and angle of the 1.5-inch viewfinder can be adjusted to fit the needs of different camera operators. The eyepiece is provided with a vision correcting mechanism (focusable).

In addition to indicating ON AIR the tally lamp also indicates VTR START /STOP and CALL from the CCU.

The camera is provided with a MIC INPUT jack for audio. It also has a built-in amplifier that provides a gain of - 60 dBm to 0 dBm

unbalanced and -60 dBm balanced output, a feature that enables simultaneous video-audio recording for different VTRs.

· An intercom jack and an intercom mic ON/OFF switch are also provided.

· Level suppression:

Controls for knee point and slope are provided to accommodate

scenes with high contrastrange. (300%)

· Provision of a special bracket for the battery pack permits simple mounting/ dismounting of batteries.

· A dynamic character display unit (optional) displays the status of different functions in the viewfinder. This permits easy monitoring of camera status even while using the camera. Status for battery, white balance, gain, VTR, genlock, and filter position are displayed.

System Connection Features

· A built-in genlock feature (standard) makes external sync (VBS/BBS signals) operation possible by a coaxial cable.

· When the supply of genlock signals stop, the camera is automatically switched over to the internal sync operation.

· There is easy control of subcarrier phase and horizontal sync phase at the camera head.

· Horizontal and vertical blanking widths can be controlled separately · SC-H phase relationship meets EIA RS-170A. · Gamma correction is continuously adjustable in each video channel to permit easy matching to other cameras.

· By connecting the CCU-730A, a variety of remote control operations, such as those shown below, are possible.

1) Iris4) R/B pedestal

3) Master pedestal6) Painting with R/B-knob

7) Auto white setting11) NOR/MID/HIGH (0/ +9/

8) Color bar switching phase+ 18 dB) Gain switch over

9) Subcarrier phase control12) Camera call

The 5- inch viewfinder is equipped with a tilting mechanism mount for studio use. (A 1.5- inch viewfinder for portable use is also available. )

Maintenance Features

· To facilitate adjustment of the infinity distance and rotation mechanism of the pickup tubes, a dual lock system has been adopted.

· The filter disc is easily removable to facilitate mounting/dismounting of the disc and cleaning.

· Plug-in printed circuit boards are divided according to circuit

function; all major controls are arranged in front of each unit to

expedite adjustments.

· To allow for speedy maintenance operations, the camera is provided with the following two structural features:

1) The provision of multi-connectors to facilitate mounting/ dismounting of each unit.

2) All components such as switches and connectors are grouped

together, block by block, with the blocks, in turn, interconnected by connectors.

· Convenience is offered for level checks and registration matching, because the camera is equipped with an "R.G.B. minus G" monitor selector switch. It is designed so that each signal will be fed out to the VF as well as to the test monitor connector.

Camera Control Unit

· The ITC-730A CCU mounts into a 19" rack, height is 3.5 inches. · The CCU-730A compensates for cable lengths up to 300 meters. Cable diameter is 13 mm. Cable compensation positions are 15/100/200/300 meters.

· The standard unit can be operated from Camera Head power, a battery, or other D.C. power source.

· Horizontal phase is automatically controlled by APC (Auto Phase Control) system regardless of cable length.

· R, G, and B signals (with one channel provided for each),

Power Supply System

. The camera head accepts a single + 12 Volt power supply which can be either a battery pack, an AC power pack (ACP-35), a CCU, or other comparable power sources (such as a car battery). . Based on a switching regulator system, the AC power pack is both compact and light. It also employs a remote sensing system which makes available an automatic supply of a fixed voltage to the camera regardless of how long the cable is.
