Three 1
⁄4-inch Progressive CCDs
Three newly developed 1
⁄4-inch progressive scan CCDs—one each
for red, green and blue—provide rich, accurate colors. To separate pri-
mary colors, JVC has incorporated a high accuracy Fujinon glass prism
and the proprietary mounting technology.
Spatial Offset Technology
The Red and Blue pixel locations are shifted relative to Green,
allowing the sampled luminance information to be significantly
increased in both horizontal and vertical directions. This results in
much higher resolution images without sacrificing sensitivity.
Fujinon 10:1 Zoom HD Lens
The GY-HM100U utilizes a high definition lens by Fujinon, world
leader in HD lens technology. This lens features 3 aspheric elements
which minimize the weight
and space required, while
producing less distortion,
ghosting, and flare. In addi-
tion, the lens surface is coated
with a new Electronic Beam
Coating (EBC) that greatly
reduces degradation caused
by light reflecting off the lens
surfaces leading to greater light transmission and reduced flaring and
ghosting. To protect the lens, a flip-in cover is provided, eliminating
the need for an external cap.
Focus is controlled manually or automatically. A smooth servo zoom
is controlled with a conventional rocker on the handgrip, or manually
on the lens. For close-up shooting, a macro mode allows for shooting
subjects as little as 2-inches away from the lens. Exposure (iris) is auto-
matically or manually controlled, letting the shooter adjust the depth
of focus by selecting the appropriate F stop. The current F stop is
displayed in the viewfinder in the manual mode.
An advanced JVC-developed Optical Image Stabilization (OIS)
system provides effective camera-motion compensation without any of
the quality loss associated with digital image stabilization systems.
Newly Designed 1080p Digital Processor
JVC's digital signal processor (DSP) processes all images as full
1920x1080 progressive signals, providing the maximum image infor-
mation to work with regardless of
the actual recording mode that is
used. Also integrated into the chip
are five digital noise reduction tech-
nologies that evaluate the signal and
apply the appropriate compensation
while increasing vertical resolution
by about 30%.
Secure Digital High Capacity (SDHC) memory
card recording
The GY-HM100 records on widely avail-
able SDHC Class 6 memory cards, present-
ly available in capacities up to 32GB. The
camera provides 2 memory card slots, for a
total of up to 64GB of on board storage—
enough for more than 6 hours* of contin-
uous HD recording. (The camera automat-
ically begins recording on the second card
when the first card fills up.) Being able to
quickly switch cards with dual slots is
invaluable in a breaking news situation
where a producer may wish to begin editing while the shooter is still
capturing footage.
*When recording in 19Mbps mode
SDHC cards are highly reliable with no moving parts, no pins to
break nor sockets to clog. Unlike competing solid state media, the
per-minute cost of SDHC memory is comparable to video tape.
Moreover, SDHC media is the first practical solid state solution to
physical archive.
Still picture capture capability
Create 2 megapixel still images (1920 x 1080) with either a live
grab, or from recorded video. Since the CCDs are progressively
scanned, still images are crystal clear, even if there is motion in the
scene. With the GY-HM100, you can copy or move still images from
one memory card to another allowing you to store still images on one
card, and video on the other.
Uncompressed Audio with Manual Controls
The GY-HM100 records 2 channels of uncompressed LPCM (linear
pulse code modulated) 16 bit audio sampled at 48Khz. Audio levels
can be controlled manually, or automatically using AGC. An audio
meter is provided in the LCD and VF displays to facilitate adjustment.
Balanced XLR connectors are provided on the handle for an external
microphone and/or wireless receiver. 48V phantom power is available
for each microphone. Versa-
tile input switching allows
the microphone signal to be
directed to the desired chan-
nel. A shotgun microphone is
provided, as well as a built-in
stereo microphone for ambi-
ent sound pickup.
JVC Original 35Mbps MPEG2 Encoder
Drawing from its experience in developing rack mount encoders
used by major television stations, JVC developed a proprietary codec
capable of providing highly efficient
compression up to 35 megabits per
second, a bitrate that can support
full 1920 x 1080 encoding. This is
significantly higher than the data
rates used in other hand held cam-
corders and results in recorded
images of exceptional quality.
MPEG2 long GOP is the most
widely accepted broadcast stan-
dard compression supported by all
popular editing systems and
broadcast servers.
The GY-HM100 supports all major HD signal formats including
1920 x 1080, 1440 x 1080 and 1280 x 720.
Native File Recording
The GY-HM100 incorporates JVC's Native File Recording technology
that stores video in the ready-to-edit format used by Apple's Final Cut
Pro™ non-linear editing system. The ".mov" files created in the camera
can be easily dragged onto the NLE timeline without conversion or
rewrapping, saving time while keeping the recorded material first gen-
eration. There is no need to use an intermediate codec.
The camera can also store files in the ISO Base Media File Format
(MPEG-2 Long GOP), compatible with all major non-linear editing
systems. In this mode, the files and folders are recorded so that they
can be easily accessed in the post production process.
The GY-HM100 records audio as uncompressed LPCM data in both
Final Cut Pro™ and ISO formats.

Operational/Ergonomic Features
Compact Hand-held Form Factor
The GY-HM100 is the smallest pro format 3-CCD camcorder available—
about the size of the lens of a 2/3-inch camera. At only 3.3 lbs, it can be used
comfortably for hours, and without the need for clumsy support bracing. Its size
makes it ideal for hand-held POV use and for applications where a full size
camera would be impractical such as traveling into potentially hostile situa-
tions. For a smaller footprint and less conspicuous shooting, the handle can be
easily removed. When media needs to be concealed, Micro-SDHC memory cards
can be used with a card adapter.
Shooter-friendly controls and layout
The camera's hand grip has a comfortable, familiar feel comfortably accom-
modating hands of all sizes. Controls and switches are right where you'd expect
them. To conserve on space, a single ring is used for both manual focus and
manual zoom. When holding the camera by the grip, zoom and trigger controls
operate the same as on full size cameras.
Patented "FOCUS ASSIST" function
Achieving exact focus with HD signals is critical. JVC's Focus Assist turns
focusing into a fast, easy and accurate process. When Focus Assist is activated,
the picture in the viewfinder becomes monochrome and all objects which are
in focus take on a colored fringe. Focus Assist works equally in the viewfinder
as well as on the LCD panel. The Focus Assist function can be assigned to one
of the three USER buttons.
Versatile Manual Controls
When operating the camera in the manual mode, depth of field can be
adjusted by manually setting the iris. Aperture priority automatically selects the
correct shutter setting based on the iris selection. Shutter can be manually
adjusted from 1/4 to 1/10000 sec.
2.8-inch LCD Display
The 2.8-inch LCD offers a 16:9 aspect ratio and provides a wide array of mon-
itoring and setup indications. It is especially designed to cut surface reflections
and glare to maintain a clear, visible, bright view during outdoor recording. Menu
items are easily selected using a small joystick and push buttons.
Wireless Remote Control
A simple infrared remote control unit (provided) allows the camera to be oper-
ated remotely. This is especially useful at events when the camera is used to cap-
ture POV shots when an operator is not available.
