FeatureContents
Thank you for purchasing the
DZ-VCA3U MICRO HD CAMERA.
• Compact, lightweight design
Thanks to the incorporation of 1/3-inch CCDs, the camera
head’s outer dimensions have been reduced to a compact
44 (W) x 51.4 (H) x 57.7 (D) mm and its weight to only
100g.
• High resolution
A total of three VGA 1/3-inch CCDs are used (for each R, G
and B). With digital signal processing, this camera is able to
produce extremely high horizontal resolution (750 TV lines)
and vertical resolution (700 TV lines). The aspect ratio is
4:3.
• System construction
HDTV studio standard (compliant with ITU-R Rec.709)
sync signals are used, allowing recorded picture to be
played back with high picture quality when an HDTV VCR
such as the W-VHS VCR is used.
• Automatic sensitivity control
The automatic sensitivity control combines automatic
sensitivity control with ALC and electronic iris (ALC +EEI)
to allow trouble-free shooting xh intensity.
• Electronic shutter function
A built-in 1/10000-sec. electronic shutter function allows
capture and analysis of fast-moving subjects.
• Flicker-free mode
Greatly reduces the flickering caused by shooting under a
fluorescent lamp in locations using 50-Hz cycles.
• Colour bar generator
A full colour bar generator is built in for easy system
adjustment.
• Automatic internal/external sync switching
Useful for systematic operations, such as multicamera
video processing, in combination with other devices.
• 2H contour provided as standard
Contour compensation is performed both horizontally and
vertically to assure sharp, clear pictures.
• JVC cannot be responsible for any loss or damage to
recorded material in the event that the colour video
camera, VCR, or video cassette malfunctions during
recording.
