Phenomena Specic to CCD Image Sensors

The following phenomena that may appear in images are specic to CCD (Charge
Coupled Device) image sensors. They do not indicate malfunctions.

White ecks

Although the CCD image sensors are produced with high-precision technologies,
ne white ecks 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 ecks especially tend to be seen in the following cases:

- when operating at a high environmental temperature

- when you have raised the gain (sensitivity)

- when using the slow shutter

Vertical smear

When an extremely bright object, such as a strong spotlight or ashlight, is
being shot, vertical tails may be produced on the screen, or the image may be
distorted.
