Features
High picture quality
The DXC-930/930P 1/2-inch CCD color video camera
can produce high quality pictures thanks to adoption of a
high performance three-chip CCD pickup having about
380,000 (DXC-930) or 420,000 (DXC-930P) effective
picture elements. Three features of the camera that
combinedly ensure high picture quality are:
¢ High horizontal resolution: 720 TV lines;
© High sensitivity (defined as minimum required
illumination): 2,000 lux at f/5.6 (DXC-930) or
f/5 (DXC-930P);
© High signal-to-noise ratio: 58 dB (DXC-930) or
56 dB (DXC-930P).
Very small size and light weight
Being very small and very light, the camera can be
installed easily and safely even in strictly limited spaces
where other small-sized video cameras cannot be. This
feature makes it possible to use the camera in an
inconspicuous manner. The following are some examples
of application:
© Installing on ceilings, walls, pillars or other building
members of theaters, concert halls, and so on;
© Incorporating in video conference systems;
© Using as a microscopic or endoscopic system component;
© Using as a roof-top weather monitor camera.

Wide range of incident light control
Thanks to its AGC (automatic gain control) and CCD iris
control capabilities, the camera can cope with even great
variations in the illuminance of the subject to produce
clear and sharp pictures. When shooting under low light,
the AGC feature automatically increases the video gain
up to eight times. When the amount of incident light is
excessive, the CCD iris control feature automatically
increases the shutter speed to nearly the same effect that
the lens iris is narrowed three stops down.
You can use AGC and CCD iris control combinedly with
automatic lens iris control. Combined use of AGC and
CCD iris control will also be very advantageous when
using the camera with a microscopic system.
Etectronic shutter to help overcome difficult
shooting conditions
A wide speed range electronic shutter function helps you
to overcome awkward shooting conditions. It gives you
clear pictures of limited blur even when the subject is fast
moving, and acceptably bright still pictures of low-
illuminated subjects. When set to flickerless mode, the
electronic shutter allows you to take flickerless pictures
even under fluorescent light. Furthermore, when you use
the electronic shutter in Clear Scan™ mode, you can
shoot computer screen displays without horizontal stripe
noise.
