‹ Phenomena inherent to CCD imaging device
Following are phenomena inherent to a CCD imaging device , and not defects.
z Smear and blooming
When strong light (lamp , fluorescent lamp , reflected light , etc.) is shot , pale bands
are displayed vertically above and below the light.
In this case , change the angle of the camera so that such strong light does not enter
the camera through the lens.
z Fixed pattern noise
When the camera is operated in a high temperature , fixed pattern noise may appear
on the entire screen.
The higher the sensitivity of camera , the more this fixed pattern noise appears.
z Moire
When fine patterns are shot , moire may be displayed.
z The CE mark is required when exporting to Europe. Obtain the necessary
authorization for the customer’s system. Enclose the camera in a shielded case and
use shielded cable.
