The SK-HD1300 is a multi-format portable HDTV Studio camera. Its new MOS sensors, each having 2.6 million pixels produce outstanding imaging performance.
The camera offers progressive HD images due to Hitachi's implementation of the latest 3-MOS imaging technology. New achievements in high sensitivity and no vertical smear have been reached as a result.
Each essential part of the Hitachi SK-HD1300 camera system has
its own DSP processor. Different DSP ICs are used independently
for the HDTV camera head processing, the transmission system and
the Camera Control Unit (CCU) processing. The new, powerefficient
Hitachi's DSP processors are designed to work with any new 2K
imaging technology that is in the near future thus, offering a high
R.O.I. (return on investment)
An outstanding overall signal-to-noise ratio specification of 62dB is
achieved by use of our own low-noise circuit technology. The standard
sensitivity is rated at F10@59.94Hz (SK-HD1300)/F11@50Hz
(SK-HD1300E) with 2000 lx.
Even at high gain, clear images are obtained with little noise.
Also high horizontal resolution performance of 1100TVL (Luminance
channel) is the pinnacle of picture sharpness and is an attribute to
the claim of having the most transparent signal processing path of
any Hitachi digital camera manufactured to date.
High Dynamic Range (HDR) is a significant advancement in cam-era 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 compatibil-ity with legacy TVs using Standard Dynamic Range.
Modern HDTV lenses can still produce optical distortions. One of
these called "Lateral chromatic aberration" can be reduced in certain
lens models when used with the SK-HD1300 camera system.
The Hitachi function is called RLAC (Real-time Lens Aberration Correction)
and it dynamically corrects images using correction data
provided by the lens, through a digital interface with the camera.
Auto Chroma automatically reduces over-saturated colors in the image
caused by extremely bright and colorful objects such as emergency
vehicle lights or stage lighting L.E.D's.
Also has the effect of ‘legalizing’ the color gamut of a particular preset
masking setting.
The SK-HD1300 camera system provides plenty of power to drive 2x 24inch LCD monitors with either Hybrid Fiber Cable or Digital Triax CCUs.
The studio floor or talent monitor can be driven with SDI (digital) video for critical viewing by the talent.
Hitachi uses dependable XLR-professional type audio connectors for the 2 iIntercom headset and 2 MIC/LINE audio connections.
Precise focus can be easily achieved by the camera operator with the aid of the Hitachi viewfinder focus assist functions. They consist of a linear bar graph on the bottom of the VF raster and detail level control just for the VF video.
Hitachi's Gray-scale auto-setup accurately adjusts the video parameters of the camera by using an external known reference, under actual lighting conditions, compensating for the lens in use. Color matching can easily be accomplished by employing this unique function.
