Hitachi’s advanced digital signal processing

Each essential part of the Hitachi Z-HD5500 camera system has its own DSP. Different DSP ICs are used independently for the HDTV camera head processing, the transmission system and the Camera Control Unit (CCU) processing. The new, power-efficient Digital Signal Processors have a dynamic processing capability in excess of 30-bits per pixel, per RGB channel. Hitachi’s DSPs are designed for process of signals from progressive readout HDTV sensors. The dynamic headroom of the Z-HD5500 allows to be faithfully reproduced thus providing future advancements in dynamics handling. Additional digital encoding at the camera head and CCU provides high signal integrity for all signal outputs.
With present technology, an outstanding system signal-to-noise ratio specification of 62dB is achieved by use of our own low-noise circuitry. The standard sensitivity is rated at F10(59.94Hz)/F11(50Hz) with 2000 lx. Even at high gain, clear images are obtained with little noise.

High Dynamic Range (HDR)

High Dynamic Range (HDR) is a significant advancement in camera technology that dramatically improves picture quality and is easily visible at all viewing distances. HDR enhances images with expanded detail in blacks, brighter highlights and more accuracy in mid-tones.
The improved dynamic range contrast also increases perceived sharpness and color saturation. Multiple HDR settings for HPQ and Hybrid Log Gamma are provided for increased compatibility with legacy TVs using Standard Dynamic Range.

Ultra Gamma

It dramatically increases the exposure latitude of the camera in shooting conditions where lighting and scenery vary widely in intensity.
Seven different ultra-gamma responses are preprogrammed to suit just about every possible adverse shooting condition.

Black stretch

The Z-HD5500 black stretch function allows better reproduction of dark or underexposed areas by evenly raising the luminance response without changing the pedestal or white clip/ knee settings. It is especially useful in high contrast image venues, outdoors or sports production.

Lens optimization
Gray-Scale automatic setup

The Z-HD5500 offers Gray-Scale Automatic Setup function to optimize the optical parameters that could negatively affect the image you are trying to capture and faithfully reproduce. The Gain, Gamma, and Flare are the video signal functions that vary from lens to lens.

Automatic vertical modulation shading adjustment

The Z-HD5500 assures that with any lens used, an even, whitebalance throughout the raster will be attained by the automatic vertical modulation shading correction function. At the simple push of a button, this function provides separate memory of lens’ modulation shading characteristics to optimize the X1 and X2 lens extender positions.

Optical and image capture functions
Viewfinder Focus Assist

Three different visual aids are available to help the camera operator find the right focus: VF DTL, VF PEAKING and VF Focus Assist. The Area Marker detects edges inside area, while a focus indicator shows the actual detail level by a horizontal line. A Focus Indicator Gauge can further be set to lock the maximum achieved level for a few seconds.

Quick-focus function for Precise Focus

The Quick Focus function automatically opens the iris then sets the video level with the electronic shutter at the push of a button. The resulting shallow depth of focus, allows the cameraman to set the exact focus with ease.

Flexible Choice of Camera Control Units

5 different Camera Control Units (CCU) are offered for every budget, physical size and signal requirement for the Z-HD5500 camera system.
The Fiber CU-HD1000-S8 is half-rack model. It offers 50/60Hz line power switching and output 1080i, 720p, 576i and 480i. The reduced size, weight and low power consumption makes it ideal for more portable applications. CU-HD1000-S8 also includes a unique optical power meter that indicates the status of the HFOC.
The budget priced CU-HD500 Fiber CCU is a full rack model that outputs either 1080i or (special order) 720p. All CCU models serve applications for a variety of Studio and Field productions.
Full HD 1080 Progressive CCUs include the fiber CU-HD1200, the CU-HD1300T and CU-HD1300FT that offers fiber, triax or both camera cable options. The dual fiber and triax cable CCU is particularly suitable for venues that may have multiple cable types connecting to mobile production/OB units**. All CCUs have an easy-to-maintain modular design, employ the same control panels, data cables and peripherals.

CU-HD1300T/FT, CX-HD1300 Digital Triax System

Hitachi’s 4th generation digital triax system can transmit full 1080 progressive signals over much longer triax cable distances. The ultra- low delay H.264 codec and hybrid digital modulation technology ensures high quality picture transmission.
Signals include: video, prompter, return video, audio and all intercoms. Signal level indicators show the status of receive and transmit of triax or optical cable in the RU-1500JY Remote Control Unit and all CCUs.
In applications where traditional triax is already in use, substantial savings in the cabling infrastructure can be realized by employing Hitachi HDTV Digital Triax cameras.

  • Hitachi's patented, fully digital, bi-directional signal transmission system
  • Little to no signal degradation.
  • Capitalizes on reduced costs and flexibility of triax copper cable.
  • Includes 1080i/ 720p cross-converter for HD-SDI outputs Built in, high-performance SDTV up/ down converters
