‹Phenomena inherent to CCD imaging device

Following are phenomena inherent to a CCD imaging device , and not defects.

zSmear 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.

zFixed 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.

zMoire

When fine patterns are shot , moire may be displayed.

zThe 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.
