Phenomena inherent to CCD imaging device

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

1) Smear and blooming

When strong light (lamp, fluorescent lamp, and reflected light, etc.) is shot, a blue belt to remain thinly in vertical and the horizontal direction of light might go out.

Moreover, the lower side on the monitor screen might become pure-white momentarily.

2) Fixed pattern noise

When the camera is operated in a high temperature, fixed pattern noise may appear on the entire screen.

3) Moire

When fine patterns are shot, moire may be displayed.

4) Burning

When excessively intense light comes to the CCD for a long time, the spectral filter in the CCD pixel may be deteriorated, and the color of the corresponding portion may change.

Avoid using the camera under such condition.

In this case, change the angle of the camera so that such strong light does not enter the camera through the lens.
