Cameras And Camcorders
Contributing Editor David Kirk looks at the
latest imaging technology innovations...
content originators face an ever
widening choice of cameras and
camcorders, ranging in size and price
from 4K-capable mobile phones to
studio cameras with resolutions of
8K and higher. The following article
summarises the most recent additions
in dedicated production cameras.
Camera Corps' Qx HD camera
incorporates the features of the
established Q-Ball and Q3 plus a more
advanced camera module. Among
its new capabilities are 3D noise
reduction and shading correction.
Available both for rental and purchase,
the Qx has a 1/3-inch CMOS Full HD
sensor delivering 1080p60, 1080p50,
1080i and 720p. Shutter speed range
is 1/4 to 1/8,000 second, imaging
sensitivity is F5.6 at 2000 lux and
minimum illumination level is 1.5 lux
at F1.6. Enhanced IR capability allows
live video capture in zero visible light
conditions using infra-red illumination.
Features include an integral 18x zoom
lens, automatic exposure, auto white
balance, colour correction, edge
enhancement, noise reduction and
gamma control. Genlock allows easy
synchronisation with other equipment.
Combining the Qx with Camera Corps'
hybrid electro-optical links allows
operation across distances of five
kilometres or more.
Also added recently to the Camera
Corps range, Clarity is a miniature
high-speed broadcast camera head
which can capture HD at up
to 480fps, eight times realtime at 50p or 60p frame
rate. Finished in black and
measuring just 66x25x120mm,
the Clarity head is designed to
be almost invisible to other cameras
Clarity highspeed head
covering a scene. Image capture is via
a 7 megapixel micro four thirds sensor.
The camera can also be genlocked and
has a wide temperature tolerance,
allowing outdoor use from winter
sports to the hot mid-summer
events. Completing the Clarity
system is a full-functioned remote
control panel with paint, focus, iris
and zoom control. Optical fibre cabling
allows easy setup and long-distance
signal transport. Additional features
include a positive-lock lens mount
plus a global shutter with speeds of
1/60, 1/125, 1/500 and 1/1000 second.
Sensitivity is 2000 lux at F11 aperture.
Video can be output in 1080p, 1080i
and 720 formats at 50 or 59.94Hz.
Canon's EOS C700 camera can
operate at up to 4.5K resolution and
120 fps Cinescope shooting speed
when attached to the company's CDX36150 recorder. It supports SMPTE
ST.2084 monitoring. Features include
autofocus, built-in 10-stop ND filter
and optional wired or wireless control.
Grass Valley's LDX 86N/86 4K and
LDX 86N/86 offer the ability to shoot
4K UHD with 2/3-inch B4 mount
lenses. The LDX 86N/86 also provides
high frame rate acquisition in HD and
3G. The LDX 86N/86 can operate in
ITU-R BT.2020 extended colour gamut.
The LDX 86 Series may be softwareupgraded to offer full 15 F-stops of
high-dynamic range for all 50/59.94Hz
Hitachi's Z-HD6000 HD camera uses
2.6 megapixel 2/3-inch MOS sensors
and is claimed to deliver F12 standard
sensitivity with over 60 dB of video
headroom. Seven different responses
are provided to increase exposure
latitude in shooting conditions where
lighting and scenery vary widely in
intensity. The camera also includes
real-time lens aberration correction
and is housed in a two-piece dockable
camera body with a choice of digital
fibre or triax cable. The Z-HD6000
includes triple-masking functions,
linear matrix and skin
H D K - 7 3
the April 2017 NAB
Show, incorporates a newly
designed imaging head with three 2.6
megapixel 2/3 inch CMOS sensors.
It delivers 1,000 TV lines horizontal
resolution, greater than 60 dB signalto-noise and F13 sensitivity.
User-adjustable gamma for HDR
picture origination is provided,
scenes to be
televised with full picture detail across
the entire brightness range from
highlights to shaded areas. Full
digital signal handling is performed
by a newly developed processor
operating in up to 38-bit depth.
The camera outputs in either
1080i or 720p and can interface
with portable recorders via SDI to
control the record trigger. In standalone configuration, external devices
such as wireless transmission or a
can be attached. The
expander enables use
of a studio viewfinder
and full studio lenses,
converting the portable
camera into a full
facility studio camera. Optional
controllers include the OCP-300
which supports Ikegami's conventional
control, Arcnet based control systems
and Ethernet based control. The
OCP-300 includes a touch screen
LCD with rotary encoders and an SD
memory card slot for full camera
setup and data filing. Also available
is the compact OCP-10 which can
control basic functions such as iris,
white balance, black balance, paint,
gamma and master black. The OCP10 supports Ethernet based control
allowing customers to choose between
Ikegami's traditional ICCP control and
Ethernet based control system.
Also new from Ikegami is the UHK430 4K/HD portable camera system.
This employs three newly-developed
4K-native 2/3 inch CMOS sensors
which provide full 3840 x 2160 ultrahigh definition resolution plus the
depth of field required for studio and
outdoor production. The camera head
can be detached as a compact unit and
operated up to 50 metres from the
camera body. A high frame-rate option
is available for slow-motion effects.
