3-CCD camera system with 720p HD CCDs
The GY-HD250 uses three 1/3” high definition CCD image sensors.
Each array has a pixel resolution of 1280 x 720 and uses a micro lens
system. Since this native resolution matches that of most HDTV
displays, the need for image scaling is eliminated, further enhancing
the quality of the recorded images. Other advantages of these CCDs
include sophisticated circuitry that virtually eliminates lag and image
burn.
Uncompressed 720/60p live signal output
In addition to providing superior quality HD recording in the HDV format,
the GY-HD250 can capture and output both digital and analog HD
signals at 60 frames per second. Ideal for live broadcasting, the
uncompressed full-resolution signal (either 720p or converted 1080/60i)
can be output via the built-in HD-SDI and component analog terminals,
providing an ideal feed to a video server, HD switcher or microwave link.
Professional functions
Compact shoulder mount design
JVC’s ProHD camcorders are the only professional HD camcorders to
feature a compact shoulder mount design. Like its predecessors, the
GY-HD250 offers excellent mobility and enhanced usability, while its
flexible range of ergonomic adjustments ensures that camera operators,
regardless of stature or physique, can support the camcorder steadily
and, above all, comfortably.
Professional functions and switch layout
In addition to the Full Auto Shooting to handle difficult or variable
lighting environments, the GY-HD250 is equipped with an array of
functions that give professionals creative flexibility. These include,
amongst others, zebra, gain, white balance and full shutter control.
Also, the GY-HD250’s switches have been positioned where
professional camera operators can expect them. This helps make
shooting more intuitive, precise, easy, and error-free, because the
learning process is minimized dramatically, making the GY-HD250 the
ideal camera for any assignment.
Detachable 230,000-pixel LCD color viewfinder
The viewfinder’s eyepiece can be moved backwards and forwards and
can also be adjusted laterally for left or right eye shooting, enabling it to
fit the operator comfortably. JVC’s own proprietary and patented Focus
Assist control ensures fast and easy
focusing. To make focusing even easier,
a black and white mode is available.
Stronger contrast and reduced color
noise make visualization and
composition easier in this mode and
put less strain on your eyes so you can
shoot for longer periods. You can also
keep using the viewfinder even when
using the LCD display. When not
required, the viewfinder may be
detached.
