A Studio and EFP Camera System for Broadcast Use

That Delivers High-End Image Quality and Enables
Long-Distance Optical Fiber Transmission at Low Cost.
This cost-effective HD camera system with optical ber
transmission capability meets the high-end TV program
production needs of broadcast studios.
The newly developed AK-HC3800 Studio Handy Camera
is equipped with a high-sensitivity, high-quality 2/3-type
2.2-megapixel 3CCD and a new high-precision 16 bit
A/D image processing circuit. The advanced digital functions
such as Chromatic Aberration Compensation (CAC), Digital
Extender, Film Rec Gamma, Dynamic Range Stretch (DRS)
and etc. realize high image quality and versatile operations.
By using the AK-HC3800 together with the AK-HCU200
Camera Control Unit, AK-HRP200G Remote Operation Panel
and AK-HVF70G 17.8 cm (7 inches) LCD Color Viewnder,
an optical ber transmission studio camera system that
achieves high image quality, uncompressed and long-
distance transmission, can be congured at a low cost.
The camera and camera control unit can be connected
for long-distance transmission of video signals over
approximately 1,200 m (1,312 yards) when power is
supplied from the camera control unit.
The camera control unit and remote operation panel are
connected by a dedicated cable. A LAN cable can also
be used in the future for an IP connection of these units.*
Overall, the system is easy to use and operate, and offers
excellent cost-performance.
* To be supported from the spring of 2013.
* The photo shows a system example of the AK-HC3800GS (LEMO connector model).
* For studio zoom lens use, the lens support devices recommended by each lens
manufacturer are required. The AK-HBU3500 build-up unit is not supported.

High Quality Images Achieved by a
Newly Developed DSP.
Advanced Digital Technology Allows
Compact, Lightweight Lenses to
meet
Studio Production Needs.
3CCD with High Sensitivity, Low Noise and Low Smear
The 2/3-type 2.2-megapixel 3CCD enables the standard sensitivity
of F11 (2,000 lx/59.94 Hz) which is one of the highest sensitivity in
this range of cameras. A high S/N ratio of 60 dB (at 59.94 Hz)
produces high quality images with low noise and low smear.
Panasonic's single-channel transfer system and spatial-offset
processing technologies also improve signal modulation depth and
reduce moire.
With spatial-offset processing, green
samples are offset, allowing change in the
object to be more faithfully reproduced.
With spatial-offset processing, the depth of
modulation of high-frequency signals is
greatly improved.
New High-Performance DSP Provides 16 bit A/D,
38 bit Processing
HD images are digitized with
74 MHz sampling and 16 bit A/D
conversion. Full 38 bit
processing within the DSP
produces highly detailed,
high quality images.
50 Hz/59.94 Hz Switchable
High-Performance DSP
HD recording is switchable between 1080/50i (50 Hz) and
1080/59.94i (59.94Hz) for worldwide production use.
Chromatic Aberration Compensation (CAC)
This exclusive technology sets up a conversation between lens and
camera which allows for a highly sophisticated algorithm to be
deployed that will automatically compensate the registration error
that is caused mainly by lens chromatic aberration, and minimize
the circumjacent blur. * When a CAC-compatible lens is used.

the image inversion that happens when using a Canon or
Angenieux HD lens adaptor, and the AK-HC3800 supports
interchangeable lenses for film cameras.
Dynamic Range Stretch (DRS)
The DRS function automatically suppresses blocked shadows and
blown highlights. A gamma curve and knee slope are estimated to
match the contrast of each pixel, and applied in real time. When
dark, bright, and intermediate shades are all contained in the same
scene, this produces excellent gradation for each shade. The
images that result are enhanced by a visually wide dynamic range.

While suppressing washed out colors such as those when shooting garden greenery,
it also reduces blocked shadows in dark areas when recording people indoors.
Other Advanced Digital Functions
• Selectable EBU or NTSC preset matrix
• 12-axis color correction, linear matrix, and other color correction
functions
• A skin tone detail function with two skin tone settings
• A lens file function (for up to 32 files) to save flare and shading
values.
• Camera settings, such as VF settings, can be saved on an SD
memory card. SD memory cards can also be used for firmware
upgrades.

Digital Extender (2x)
This function expands the image by 2x in the digital signal
processing circuit, allowing powerful shooting even with a
low-magnification lens. HD images retain their superior resolution
even with zooming, and — unlike when a lens extender is used —
brightness is not reduced.
Film Rec Gamma and Scan Reverse Functions
Selectable gamma curves are included in the DSP circuit. The Film
Rec mode produces the kind of film tone that you get with
