High Image quality
is vital to all surveillance cameras.
The i-Pro megapixel network cameras are equipped with a progressive
scan 1.3 million pixels CCD and proprietary DSP that delivers
outstanding image quality. The image is so detailed that it allows
operators to identify subjects on a whole new level when compared to
existing analog TV standard systems. Alternatively it can capture an
area four times larger while maintaining the same image quality of
conventional cameras.
- Applicable models: WV-NF302, WV-NP304, WV-NP1000
Series

Interlaced video
produced by an interline transfer CCD
has motion blur and tearing problems. This is caused by the timing
difference between odd fields and even fields, which gives the image a
jagged appearance. This has been a particular problem with conventional
surveillance cameras. The i-Pro network cameras provide progressive
video output by using a progressive scan CCD or Motion Adaptive
Interlace-Progressive conversion, * ensuring clear images with less
motion blur and no tearing even when the subject is moving.
*Progressive scan CCD: WV-NF302, WV-NP304, WV-NP1000
Series, WV-NP240 Series, WV-NF284 Motion Adaptive Interlace-Progressive
conversion: WV-NW484S, WV-NS202A, WV-NS950 Series, WV-NW960 Series

ABS (Adaptive Black
Stretch) increases visibility of
subjects in dark areas without degrading image quality in bright areas
by analyzing the “illumination map/signal level distribution?
and adjusting gamma correction for each area separately.

When there is a high
contrast between dark and bright
areas, it is difficult to reproduce an image satisfying both dark and
bright areas. Dark areas disappear if the camera sets its iris to
capture the bright areas. Conversely, if the iris is adjusted to the
dark areas, bright areas will be washed out. This has been a particular
problem with conventional surveillance cameras. Super Dynamic III uses
a double speed CCD and a proprietary DSP including Area Free
(Pixel-Based) Natural Contrast Image Correction to optimize contrast
and faithfully reproduce objects in every area and every level of
brightness. Pixel-Based Super Dynamic III delivers smoother natural
reproduction regardless of position, size, shape or number of
bright/dark areas.

All i-Pro network
cameras combine high sensitivity
design and electronic sensitivity enhancement functions, enabling them
to capture color images even when the lighting is dim. If the situation
is too dark, the Day/Night Switching feature * automatically switches
the camera from color to B/W, perfect for 24-hour surveillance.
* Except for WV-NP240 Series, WV-NF284

Conventional analog
slip ring transmission requires a
DA-AD conversion and YC mix/separation process that causes image
quality deterioration. It was believed that slip ring throughput is not
fast enough to send a digital video signal, which requires 250 Mbps at
VGA resolution. Panasonic has solved this problem by using Low Voltage
Differential Signaling (LVDS) technology allowing the slip ring to
transmit a video signal of up to 500 Mbps. With this technology,
Panasonic digital slip ring transmission can transmit a digital video
signal without the DA-AD conversion and YC mix/separation. Throughout
the process, the signal remains digital resulting in no loss of image
quality.

The WV-NP1000 Series
and the WV-NW484S are equipped with
ABF (Auto Back Focus), which automatically adjusts back focus by
adjusting the CCD position. ABF can eliminate the time required to
manually adjust focus when installing cameras or changing location,
lowering installation and maintenance costs. It can also be
automatically activated when switching from color to B/W mode or vice
versa providing the best focus in each mode. This results in a precise
focus 24 hours a day, both during the day and at night. The WVNF302 and
WV-NP304 are equipped with a Focus Assist function, which indicates the
best focus position by on-screen display so that accurate focus
adjustment can easily be made.

It is necessary to
amplify the image signal when
capturing images under low light conditions. This, however, causes an
increase in noise as well. In the i-Pro Series, 2D-DNR for motion area
and 3D-DNR for static area are effectively combined, realizing a clear
low noise image with less motion blur and resolution deterioration.

The WJ-GXD400 Multi
Channel High Definition Video
Decoder is equipped with a HDMI video interface and can provide 1x XGA
(1,280 x 960) image with 2x VGA images in 3 split screen or 6x VGA
images in 6 split screen allowing precise identification and
multi-screen monitoring. Each VGA image can be displayed at 30 ips so
that decisive moments can be monitored.
