Hitachi’s SK-HD1800 broadcast studio and field production cam- era is a full-featured, uncompromising system that meets the most demanding studio and field applications. It incorporates a new gen- eration of high-performance, 2/3-inch, Global Shutter, CMOS, Full Frame sensors. The SK-HD1800 delivers 1080 progressive image acquisition, processing, transmission and outputs throughout the entire camera chain.
Regardless of your cabling choices, Hitachi provides full progressive transmission over Single-mode fiber, SMPTE Hybrid fiber or Triax- ial cables. The SK-HD1800 retains all the popular functions and features of the existing Hitachi SK broadcast camera line. As an option, signal delivery is now available with SMPTE 2110 compliant network connections for implementation in hybrid (SDI or, IP) facili- ties.
High Dynamic Range (HDR) for HDTV production is fully exploited in the SK-HD1800 camera system and is included as standard. HDR is available in two world-wide standards; Hybrid-Log Gamma (HLG) or Perceptual Quantization (PQ/ SMPTE 2084). HDR delivers a dramatic improvement in picture reproduction when viewed on a compatible monitor or TV.
The Hitachi SK-1800 system camera optionally features a high-qual- ity 3840 X 2160 UHD signal synthesized from the fully-progressive camera system. This 4K signal is available with Fiber or Triax cable transmission in the CU-HD1300 series CCUs that works with all our progressive camera systems.
Hitachi has achieved a new level of HD camera performance with a new generation of CMOS Full Frame progressive scan imagers. Using these newly developed progressive scan CMOS imagers, the SK-HD1800 easily handles difficult mixed frequency LED lighting and display situations.
The new sensors also enable the SK-HD1800 to achieve outstand- ing resolution, dynamic range, sensitivity and absence of vertical smear. A high horizontal resolution of 1000TVL (Luminance channel) offers very high picture sharpness with low noise and ultra-low verti- cal smear.
The SK-HD1800 takes full advantage of the increased dynamic range output performance of the NEW Global shutter CMOS imag- ers and the widened spectral response of the optical system.
A wider exposure latitude is now available to capture the most chal- lenging scene and lighting conditions which is especially important when applying modern HDR (High Dynamic Range) workflows.
With HLG-600/1200 and HPQ HDR functions in the SK-1800 series camera system, you’ll see deeper blacks, increased detail in mid- tones, brighter highlights and vivid colors; all resulting in a dramatic improvement in picture quality easily visible at all viewing distances. HDR is available as standard on 2K and 4K SDI outputs on the 1300-series CCUs.
The SK-HD1800black stretch/ press function allows better repro- duction of dark or underexposed areas by raising or lowering the luminance response of dark zones in the image without changing the black, master gamma, white clip or knee settings. It is especially useful in high contrast image venues, outdoors or sports production.
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-HD1800 camera system. The Hitachi RLAC (Real-time Lens Aberration Correction) function dy- namically enhances images using correction data provided by the lens through a digital interface with the camera. This corrective ac- tion takes place as the lens zoom, focus and iris are operated.
The SK-HD1800 offers through-the-lens Gray-Scale Automatic Set- up function to optimize the complete image reproduction system. Video parameters like Gain, Gamma, and Flare are the video signal functions that could vary from lens to lens are consistently corrected accurately.
