Typical CCD Phenomena
Vertical aliasing
When you shoot vertical stripes or lines, they may appear
jagged.
Blemishes
A CCD image sensor consists of an array of individual
sensor elements (pixels). A malfunctioning sensor element
will cause a single pixel blemish in the picture. (This is
generally not a problem.)
White speckles
When you shoot a dark object at a high temperature, small
white dots may appear all over the image.

Very bright object
(electric lighting,
the sun, strong
reflection, etc.)
The following effects on the monitor screen are
characteristic of CCD cameras. They do not indicate any
fault with the camera module.
Smear
This occurs when shooting a very bright object such as
electric lighting, the sun, or a strong reflection (shown
below).
This phenomenon is caused by an electric charge induced
by infrared radiation deep in the photosensor. It appears as
a vertical smear, since the CCD imaging element uses an
interline transfer system.
