Hitachi’s SK-HD1500 High speed HD Camera Studio and Field Production Camera

  • Latest Advanced High Speed Scan Sensors
  • Advanced 16 bit ADC and 38 bit DSP
  • Slow Motion Camera with 3x and 1x speed simultaneous HD Outputs

The SK-HD1500 is HITACHI’s fifth-generation, triple-speed, slow-motion HDTV Studio and Field production camera. It has been especially developed in response to increased market demand for the acquisition of high-quality HDTV images in sports and action events.
The pristine image starts with an excellent signal-to-noise ratio of 58dB which is attained by employing the latest Ultra-Advanced, High-speed/Sensitivity CCDs, state-of-the-art 16-bit analog to digital converters and patented HITACHI digital processing technologies.
The camera system outputs these slow-motion frame rates: 1080i/180 or 1080i/150, 720p/180 or 720p/150. It simultaneously outputs normal speed images [1080i/60, 1080i/50, 720p/60, 720p/50] from its camera control unit (CCU) thus allowing dual recording of 2 different HD signals.
The SK-HD1500 can effectively be deployed in camera positions within a venue replacing normal frame-rate HD cameras costing just as much.

Camera power and cable condition supervision are also performed when using standard SMPTE311-type Hybrid Fiber Cable. Full Auxiliary (up to 4 digital, HD or SD) video return and individual trunk video function for one HD-SDI that use the space band of 1.5Gbps except triple speed band of 4.5 Gbps are with a total of the SK-HD1500 transmission system. The maximum HFOC length with applied camera power and fully operational facilities is 4,000m (13,200 feet) with no utility power.

Unique to cameras in the SK-HD1500’s price range are optical power meters at the camera head (via engineering menu) and on the front of the CU-HD1500 camera control unit. These meters indicate the optical condition of both the receive and, transmit signals independently to accurately depict the proximity to the “digital cliff”, maximum cable distance or provide basic fiber cable diagnostics in the field.

Luminance response tools

Ultra Gamma

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

Black stretch

Black stretch function allows for 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 sport productions.

Lens optimization

Gray-Scale automatic setup

The SK-HD1500 offers the 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/Horizontall modulation shading adjustment

The SK-HD1500 assures that with any lens used, an even, chroma response will be attained by the automatic vertical/Horizontall 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

Advanced Flicker Reduction Function

The video flicker seen in a modern HDTV slow-motion camera is mainly caused by the asynchronous frequencies between the camera's CCD scanning and the charge-discharge cycles of artificial lights typically used in stadiums, arenas and auditoriums.
The SK-HD1500 can minimize the observed flicker in the image by its unique, automatic flicker-frequency detection algorithms which use the actual level fluctuations in the captured video frames to correct the flicker in real-time.
The optimum r eduction in flicker can be thus easily obtained by adjusting the detection response and method via the SK-HD1500 operational menu.

Focus Assist

Advanced Focus Assist Functions are available to support the camera operator in finding the right focus regardless of the viewfinder model used. 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 + Precision Focus (Auto Focus)

The Quick Focus function automatically opens the iris then sets the video level with the electronic shutter. The resulting shallow depth of focus, allows the cameraman to set the exact focus with ease.
Lenses with Precision Focus(Auto Focus) technology are supported equally.
