"The 2018 summer of sport encouraged many production companies to invest in High Dynamic Range which enables them to capture images with a much wider dynamic range than previously possible," comments Michael Lätzsch, Broadcast & Professional Video Division Manager at Ikegami Electronics (Europe) GmbH.
"Lighting in television studios is carefully controlled to prevent over-exposure of highlights or corresponding under-exposure of shaded areas. Broadcasters televising large public events from locations such as open-air stadiums or theatre auditoriums face the much greater challenge of real-world lighting; from very bright sunlight on white stadium canopies to the darker detail of shaded viewing stands."
He adds further: "4K UHD is also attracting an increasing level of attention from content producers as a way to maximise the long-term value of their programmes. The HDK-99 delivers a processed output from its control unit, allowing the camera to be used in a mixed-format production environment.
"The SD to HD transition is still in progress after nearly 20 years and it is quite possible that the transition to UHD will take a similar timescale given the practicalities of delivering high bandwidth content to the viewing public. The Ikegami strategy is to support and encourage the highest possible production standards without forcing the pace of technical development faster than broadcasters choose to adopt."
Ikegami HDK-99 Full Digital 3-CMOS Full-HD 1080p HDR Camera
Debuted at the April 2018 NAB Show in Las Vegas, the HDK-99 succeeds Ikegami’s HDK-95C in the Unicam HD series. A docking-style camera for portable and studio applications, it employs three 2.6 megapixel high-performance CMOS image sensors delivering high picture quality in HDR at Full-HD 1920 x 1080 resolution with progressive-scan. Processed 4K can be sourced from the camera control unit. HLG mode maintains the high contrast required for HDR and conforms to the ITU-R BT.2100 international standard. Noise is less than -62 dB and sensitivity is a high F12. The sensors natively support 1080i /59.94, 1080i/50, 720p/59.94, 720p/50, 1080p/29.97, 1080p/25 and 1080p/23.98.
Also supported are 1080p/59.94, 1080p/50, 1080i/119.88, and 1080i/100 3G HDTV formats. Integral to the HDK-99 is the Ikegami AXII processor which allows fast and precise colour matching for live multi-camera applications. A Lens Aberration Correction function minimises resolution loss and coloured edging caused mainly by opticallens deviation. Quick EZ Focus Assist provides distinct enhancement to the viewfinder signal, enabling the camera operator to make critical focus adjustments. Area size, area colour, edge colour and display time on the viewfinder are all adjustable from the camera menu.
Ikegami HDK-73 3-CMOS 1080i HDR Camera
The Ikegami HDK-73 is a dockable multi-role 1080i high-definition camera designed for SDR and HDR broadcast production. It is available as complete system including CCU, connecting fibre, viewfinder and remote control. Image capture is to 2/3-inch 2.6 megapixel CMOS sensors, each capable of capturing Full-HD 1920 x 1080 resolution images with a dynamic range of 600% in normal mode and an extremely wide 1200% in HLG mode, high sensitivity (F13 at 50 Hz) and high signal-to-noise ratio. The sensors natively support 1080i/59.94 and 1080i/50, as well as 720p/59.94 and 720p/50 scan formats. Major features of the HDK-73 include full digital signal processing, advanced digital detail correction with independent horizontal and vertical correction of red, green and blue signals, and optional anti-moiré filtering. Hybrid log gamma processing is operator-selectable for HDR picture origination, enabling high-contrast scenes to be televised with full picture detail across the entire brightness range from highlights, mid-range to shaded areas.
The HDK-73's dockable structure allows studio configuration with fibre base stations as well as self-contained operation with a camera adapter for wireless or onsite recording applications. A fibre adapter can be attached directly to the camera head without need for external cables. External devices such as wireless transmission or a solid-state recorder can be attached for standalone operation, making the camera suitable for live sports, news gathering or field production.
NEW: Ikegami HQLM Series and HEM Series Monitors
Ikegami is expanding its range of monitors with six new models:
The HQLM-3125X HDR broadcast master monitor employs a 4,096×2,160 pixel 10-bit resolution LED-backlit double-LCD panel with a 1,000,000:1 contrast ratio and a panel brightness of 1,000 candela per square metre. Fully compliant with BT.2020 wide colour gamut, the HQLM-3125X incorporates single-channel 12G-SDI x 2, 3G-SDI × 5, 3G/HD-SDI and HDMI inputs as standard features. Square-division and two-sample interleave sources can be connected to the monitor via 3G-SDI × 4. Viewing angle for critical image evaluation is a wide 178 degrees (horizontal/vertical). In addition to its picture monitoring role, the HQLM-3125X can operate as a waveform monitor and vectorscope. It can also display vertical-interval timecode, eight channel SDI-embedded audio level and closed-caption subtitles.
The HQLM-3120W is a 31 inch 4K/HD production monitor equipped with two 12G-SDI input channels as standard for efficient configuration with 4K equipment such as cameras and switchers. 3G-SDI, HD-SDI and HDMI inputs are also provided as standard.
