Panasonic Imaging Technologies Take HD to a Beautiful New Level
3CCD
Rich, vivid colours bring out all the beauty of high definition
HD is especially good for scenes with rich, vibrant colours. And Panasonic
HD video cameras provide the best in colour reproduction, thanks to use of
an advanced 3CCD camera system. This system, in which three separate
CCDs capture and process the light information received through the lens,
helps reproduce high-resolution HD images with magnificent colour.

O.I.S.
Suppresses camera shake, so images appear sharp, even on a big-screen TV
Imagine taking video shots on a moving boat and then viewing them
on a large-screen TV. They're likely to appear blurry from the boat's
movement and unsteady hands. Panasonic solves this problem with our
O.I.S. (Optical Image Stabiliser). If you plan to view the videos you record
on a big-screen TV, be sure to get a camera with an O.I.S. system.

LEICA DICOMAR Lens
The lens is like the camera's eye – it's the first device that "sees" the subject.
If you want to capture truly lifelike HD images you need to start with a
superior lens. That's why Panasonic HD video cameras come equipped with
a Leica Dicomar lens. This advanced lens system renders finely detailed,
high-resolution images that unleash the full potential of HD technology.

High-Definition Images
HD images contain 4 times as much information as conventional standard-
definition images. HDTV has 1,080 horizontal scan lines, SDTV has 576.
That translates into much higher resolution and much finer detail.

3CCD Camera System
Most professional broadcast cameras use the
3CCD camera system, with its superior colour reproduction. In a 1CCD
system, all of the incoming light information is processed by the same
CCD. The more advanced 3CCD system uses three distinct CCDs for
processing, so there is absolutely no light loss. The 3CCD camera
system draws out the full potential of HD image quality.

O.I.S. (Optical Image Stabiliser)
Panasonic's O.I.S. minimises hand-shake. O.I.S. is
extremely effective in situations where hand-shake is
most often a problem, such as with zoom shots. The system is optical, so
there is no quality loss. Images look clear and beautiful on a TV screen.

Leica Dicomar lens
The DX1 and the SD1 boast a
Leica Dicomar lens. Developed specifically for
HD digital video cameras, these lens systems
are made using a multi-coating process that
prevents light reflection and glare, which
can make colours bleed and images appear
washed out. It also helps prevent ring of light, or "ghosts."

signals onto media such as 8-cm DVD discs and SDHC/SD Memory Cards.
