1080p Dynamic Digital Signal Processor (DDSP)
At the heart of the GY-HM150U is a custom
JVC-developed 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.
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. Furthermore,
using a global shutter, the design minimizes wobbling during quick
pans and fixed pattern noise in low light conditions, contributing to
a more stable image.
10x FUJIFILM HD Lens
The JVC GY-HM150U is equipped with a high
definition 10x zoom lens by FUJIFILM,
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 wide-angle
converter fitted.
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 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.

HD/SDRec
Standard Definition Recording Capability
Responding to the needs of the industry,
the GY-HM150U, in addition to its capability as
an HD recorder, offers Standard Definition recording
for maximum flexibility. Recording in SD provides
a time-saving alternative to down-conversion of HD material for SD
broadcasts, which is still an industry standard in many countries
worldwide. This feature offers a fundamental advantage for
professionals with time-sensitive SD workflows.
* The GY-HM150U supports all major HD signal formats including 1920 x 1080,
1440 x 1080 and 1280 x 720 as well as SD signal in DV codec.
