Ikegami Sets Focus
On 4K And HD

I

kegami, a global leader in the
development and manufacture
of broadcast-quality cameras and
production equipment, has chosen
BVE 2016 as the venue for the first
UK demonstration of its new Unicam
UHD 4K-native camera, to encourage
feedback from potential customers.
Also making their UK exhibition
debut will be the Ikegami BS-98/CCU980 hybrid 2K/4K rack-mountable
optical-fibre transmission links, and
HDL-57
compact
high-definition
camera.
Unicam UHD 4K-native camera
"The Unicam UHD 4K-native camera
is a compact and light-weight model
designed for easy integration into 4K
studio and 4K field/OB truck systems,"
comments Mark Capstick, General
Manager of Ikegami Electronics UK.
"It incorporates three 2/3-inch CMOS
sensors which provide the deep focus
capability required for broadcast
operation, combined with ultrahigh quality colour reproduction.
Uncompressed RGB 4:4:4 baseband
is delivered from the camera head
to the control unit to ensure the
highest possible transmission quality.
Ergonomic and operational features
are the same as a conventional
Ikegami Unicam HD camera. A 2/3-inch
B4-mount allows direct docking with
conventional lenses, plus a focus-assist
function."
HDL-57 Compact HD Camera
The HDL-57 is a compact highdefinition camera designed for use on
remotely controlled pan/tilt heads in
applications such as parliamentary
television or robotic studios.
It can also be deployed wherever a
high-grade fixedposition compact

Ikegami 4K native
Unicam portable camera

camera is required for intercutting
with the output from full-size studio
cameras. Camera head and controller
are housed in a single robust
rectangular unit measuring 90 x 103
x 180 mm (width x depth x height)
and weighing 1.5 kg. The HDL-57 can
be operated remotely or via its rear
control panel.
Three advanced 2.5 megapixel 2/3
inch CMOS sensors are employed
to deliver wide dynamic range and,
in principle, no smear. Each sensor
incorporates
active
processing
circuitry and delivers a digital
output to the camera's digital signal
processor, all in a very small device
with low power consumption. The
sensors are equipped with native
progressive and interlace modes.
1080/59.94i, 1080/50i, 720/59.94p,
720/50p and 1080/23.98p are
available from the camera head.
1080/23.98p output is available as an
option.
Full digital processing is employed
within the HDL-57, from imagers to
HD-SDI output, delivering high signal
integrity and high picture quality as
well as stable and reliable operation.
Master gain is processed through
a high-grade low-noise amplifier
with negative feedback. Video noise
cancellation circuits deliver images
of wide dynamic range even at high
gain level. Specified performance
parameters include F11 at 2,000 lux
sensitivity, 60 dB signal-to-noise ratio
and 1,000 television lines resolution
in 1080i format (700 TVL in 720p
format).
Among the operating features of the
HDL-57 are six-position switchable
gain (0 to +30 dB), six electric shutter
speeds (1/100 to 1/2,000
second), four-position
optical filter (100,
25, 6.2 and 1.6%)
and a two-position
electronic colour
correction
filter

compact HD camera

(3,200 and
5,600 K). The
optical filter wheel
is motorised and can be operated from
Ikegami remote control panels such as
the RM-50B and OCP-300. Using these
filters in combination, the camera can
handle a very wide range of lighting
conditions. Auto-white-balance mode
is available to cover the full range of
colour temperatures.
The Ikegami HDL-57 operates on
12 volt DC power (11 to 16 volts),
consuming 18 watts or less. It delivers
two HD-SDI outputs and has a
reference signal input accepting trilevel HD sync.

Hybrid 2K/4K Optical Fibre Links
Ikegami's BS-98/CCU-980 hybrid
2K/4K rack-mountable optical-fibre
transmission links will make their first
BVE show appearance.
When used in combination with
current Ikegami Unicam HD cameras,
the BS-98/CCU-980 can deliver
HD and 4K processed UHD signals
simultaneously.
This allows users to employ their
existing HD cameras and accessories,
including lenses, for 4K productions
as economical bridge equipment until
they are confident that 4K viewing
will become popular in the broadcast
marketplace.
