Ikegami debuts new HD studio camera system at BVE


Ikegami Tsushinki Company Limited, a manufacturer of cameras, image processing
and transmission equipment, will showcase its new HC-HD300 3-CMOS HD studio
camera system, HDK-97 ARRI large-sensor broadcast production camera and NAC
Hi-Motion II sports broadcast camera at the Broadcast Video Expo, which takes
place from 24 to 26 February 2015 in London.

The HC-HD300 is a flexible docking-style camera for studio or field operation. It is
equipped with a 1/3 inch bayonet lens mount and employs three 1/3-inch CMOS
progressive-scan 1920 x 1080 native sensors in RGB prism formation. The camera
delivers high quality pictures in all commonly used HD video formats.

Typical performance characteristics of the HC-HD300 in 1080/59.94i output mode
are 1,000 television lines horizontal resolution, 58 dB signal-to-noise ratio and
2,000 lux sensitivity (89.9 per cent white reflection) at F10 aperture. Equivalent
aperture in 1080/50i mode for this light level is F11.

Camera gain can be attenuated from mid-level to -3 or -6 dB, or increased by +3,
+6, +9, +12 or + 18 dB. Integral neutral density filters (100 per cent, 25 per cent,
6.2 per cent and 1.6 per cent) can be switched in as required, plus operator-selectable 3,200, 4,300, 6,300 and 8,000 kelvin electronic colour conversion. An
electric shutter can be set to 1/100, 1/120, 1/250, 1/500, 1/1,000 or 1/2,000 second

The camera can be operated under local control or in conjunction with a newly
developed control system. This consists of an FA-300 fibre adapter and BSF-300
base station. Light in weight and compact in size (1.5RU), the BSF-300 base station
is easily integrated into any studio, mobile truck, or portable flypack. When using a
hybrid fibre camera cable, the base station provides power to the fibre adapter and
the camera itself.

OpticalCON Duo connectors allow use of SMPTE hybrid camera cables at up to 350
metres with a two inch viewfinder or 250 metres with a seven inch viewfinder. For
longer links up to 10 kilometres between camera and based station, duplex single-mode fibre with common optical LC connectors can be deployed.

Ikegami HDK-97 ARRI large-sensor broadcast production

Also on show on the Ikegami stand will be the HDK-97 ARRI camera. Jointly
developed by Ikegami and ARRI, this is a new broadcast-style production camera
with digital cinema characteristics. The HDK-97ARRI makes it possible to employ a
large format sensor in a multiple camera operation. The result is a best-of-both-worlds image acquisition system ideal for use in multi-camera studio and field
applications, including conventional broadcast camera operation and classic video
operator control of multiple cameras.

Centred around ARRI’s Super 35mm CMOS sensor with its associated support
circuitry, the system provides cinematic qualities such as natural colour rendering,
very wide dynamic range and progressive frame rates such as 23.98p. Ikegami’s
broadcast-grade distribution allows fibre transmission via up to two kilometres of
SMPTE hybrid fibre/copper camera cable.

The HDK-97 ARRI incorporates a docking style camera head from the Unicam HD
camera series plus Ikegami’s latest 3G FPGA-based DSP. Features include complete
real time control of all grey scale, colour, and detail functions. A new 3G
transmission system transports video from camera head to CCU, as well as 3G
transmission from CCU to camera head.

NAC Hi-Motion II sports broadcast camera

The NAC Hi-Motion II sports broadcast camera is a jointly developed camera by NAC
Image Technology and Ikegami. The Hi-Motion II delivers broadcast-quality slow-
motion images at up to 20 times slowdown. The Hi-Motion II employs three-sensor
1920 x 1080 native technology and has a broadcast industry standard B4 lens
mount. Features include simultaneous record and replay (96 gigabytes), up to 1,000
frames per second 1920 x 1080 capture, integral shutter and full remote control
with paint, flicker suppression, and EVS system compatibility via an LSM panel.
