1080p Dynamic Digital Signal Processor
(DDSP)
At the heart of the GY-HM100U is a new Dynamic
Digital Signal Processor. Processing is performed on the full
progressive 1920 x 1080 signal, regardless of the camcorder’s
settings, ensuring the highest picture quality in any shooting mode.
All major HD resolutions are supported, including 1920 x 1080,
1440 x 1080 and 1280 x 720.
35 Mbps MPEG2 Encoding
The highly efficient MPEG2 codec compresses
video signals at up to 35 Mbps—high enough to
support full 1920 x 1080 resolution—for simply
stunning image quality. The MPEG2 long GOP (Group of Pictures)
codec is a widely used, broadcast-standard compression system
and is supported by all popular editing systems and broadcast
servers.
Uncompressed Audio Recording with Manual
Controls
The GY-HM100U captures audio with the same
uncompromising quality as video. Two-channel
16-bit/48 kHz uncompressed linear PCM can be recorded via the
built-in stereo ambient microphone and the detachable shotgun
microphone, or via a pair of balanced XLR connectors. Versatile
input switching and independent channel assignment allow both
mic and line-level sources (such as wireless receivers) to be
connected, and phantom power is available on each XLR connector
independently. Audio recording levels can be controlled
automatically or manually, and there's an audio level meter in the
viewfinder and LCD monitor for easy monitoring.
Three 1/4-inch Progressive CCD Design with
Diagonal Offset
The three progressive CCD design provides rich,
accurate colors, while JVC’s Diagonal Offset
technology increases sampled luminance information in both
horizontal and vertical directions by shifting the red and blue pixels
relative to the green. The result is a sharper picture without any
corresponding loss in sensitivity.
10x Fujinon HD Lens
The JVC GY-HM100U is equipped with a
high definition 10x zoom lens by Fujinon,
a world leader in HD lens technology. The design minimizes the
weight and size of the lens, while still providing exceptional HD
optical performance, with low distortion. To reduce lens flare and
ghosting, the lens surface has a new Electronic Beam Coating
(EBC) that greatly reduces the amount of light reflecting off the lens
surface, and increases light transmission.
The focal length of the lens ranges from 3.7–37 mm (39–390 mm at
35 mm film equivalents), offering a good balance of wide angle and
zoom. For wider angle shooting, the
built-in lens hood can be removed and an
optional GL-V0746U wide-angle converter
fitted. The zoom range can also be
extended with the optional GL-V1846U
telephoto converter.
Rotary Optical Image Stabilizer
With the increased resolution and sharpness of HD pictures, even a
small amount of camera shake becomes noticeable to the viewer.
JVC’s newly developed Rotary Optical Image Stabilizer (ROIS)
corrects for lateral and vertical movement of the camera without the
degradation of image quality associated with digital image
stabilization systems. The result is pristine HD images that remain
sharp and stable.

Still Picture Capture
The GY-HM100U doubles as a very capable 2-Megapixel still-
picture camera. You can capture pictures live or from video that is
already recorded, and store them to either of the on-board memory
card. What’s more, because the CCDs are progressive, every frame
is sharp and clear, even when there is movement in the scene.
