Phenomena Specific
to CCD Image
Sensors
The following phenomena that may appear
in images are specific to CCD (Charge
Coupled Device) image sensors. They do not
indicate malfunctions.
White flecks
Although the CCD image sensors are
produced with high-precision technologies,
fine white flecks may be generated on the
screen in rare cases, caused by cosmic rays,
etc. This is related to the principle of CCD
image sensors and is not a malfunction.
The white flecks especially tend to be seen
in the following cases:
• when operating at a high environmental
temperature
• when you have raised the gain (sensitivity)
The symptom may be improved by turning
off the Camera Unit and then on again.
Vertical smear
When an extremely bright object, such as a
strong spotlight or flashlight, is being shot,
vertical tails may be produced on the screen,
or the image may be distorted.
Aliasing
When fine patterns, stripes, or lines are shot,
they may appear jagged or flicker.
