Typical CCD Phenomena

The following phenomena may appear on the monitor screen
while you are using the DXC-970MD 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 an
electric charge induced by infrared radiation deep within
the photosensor 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.
