Hitachi has achieved an incredibly low noise HDTV image which is the foundation for its high performance and excellent pictur e quality. With the use of NEW 2.3 million pixels, micro-lens array, native 1080p CCDs, the SK-HD2200 surpasses the performance of all prior models. These new sensors enable the SK-HD2200 to achieve outstanding horizontal and vertical resolution, dynamic range response, sensitivity and ultra-low vertical smear characteristics.
The SK-HD2200 take full advantage of the increased dynamic range output of the NEW imagers by using the latest and most efficient, integrated16-bit analog-to-digital converters. These high speed ADCs are the bridge between the analog output of the CCDs and the advanced Hitachi processor. They assure that every nuance of the image captured and, converted to electrical energy by the sensors is interpreted in the digital domain resulting in faithful image reproduction.
Each essential part of the Hitachi SK-HD2200 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,
power-efficient Digital Signal Processor LSI's are designed under the
40nm rule with dynamic processing capability in excess of 38-bits per
pixel, per RGB channel. Hitachi's DSP processors are designed to
easily manage the higher bandwidth of progressive readout HDTV
sensors. The increased dynamic headroom of the SK-HD2200,
allows faithful reproduction of even the most contrasting images.
An outstanding overall signal-to-noise ratio is achieved by using our own low-noise circuit technology without resorting to noise filtering methods.
Even at high gain, clear images are obtained with little noise.
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.
The SK-HD2200's Black stretch function allows for better reprod- uction 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.
The SK-HD2200 offer 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.
The SK-HD2200 assure that with any lens used, an even, chroma response 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.
Advanced Focus Assist Function aids 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.
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.
