8. SUPPLEMENTAL INFORMATIONS
(1) Illuminant for better picture
(2) Smear
When the strong light hits the CCD image sensor, the image of bands in vertical direction
tray appear above and under the spot. This is called smear. Especially if the camera
shoots under the noon sun or its reflections, a candlelight in the dark, or headlights of cars,
these smears may stand out in the picture.
The CCD used in the CS4000 series is designed as very strong against the smear.
However, you may watch out for smear when shooting involves very strong light sources.
(3) Lenses
Generally, there are many kind of lenses for the video camera on the market, for example,
different aperture (iris), different focal distance, zoom lenses and so on. Those having a
shorter fool distance are called “wide-angle” lenses, and those having a longer focal
distance are called “telephoto”.
Lenses of different focal distances have special characteristics and you can take advantage
of these in shooting.
Anyhow, make choice of the most appropriate lens for your application or system.
