Typical Ccd Phenomena - Sony IPELA SNC-DF40N Installation Manual

Typical CCD
Phenomena
The following phenomena may appear on
the monitor screen while you are using a
CCD color video camera. These phenomena
stem from the high sensitivity of the CCD
image sensors, and do not indicate a fault
within the camera.
Vertical smear
A "smear" may appear to extend vertically
from very bright subjects, as shown below.
Video monitor
screen
This phenomenon is common to CCD
imaging elements using an interline transfer
system, and is caused when electric charge
induced by infrared radiation deep within
the photo sensor is transferred to the
resistors.
Aliasing
When shooting fine stripes, straight lines or
similar patterns, the lines may become
slightly jagged.
Blemishes
A CCD image sensor consists of an array of
individual picture elements (pixels). A
malfunctioning sensor element will show up
as a single pixel blemish in the image. This
is generally not a problem.
White speckles
When you shoot a poorly illuminated object
at a high temperature, small white dots may
appear all over the entire screen image.
Pale vertical smear
Very bright subject
(such as an electric
lamp, fluorescent
lamp, sunlight, or
strong reflected light)
Note on laser beams
Laser beams may damage the CCDs. If you
shoot a scene that includes a laser beam, be
careful not to let a laser beam become
directed into the lens of the camera.
