Typical CCD Phenomena
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).
Video
monitor
screen
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.
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.)
Pale
White speckles
vertical
When you shoot a dark object at a high temperature, small
streak
white dots may appear all over the image.
Very bright object
(electric lighting,
the sun, strong
