Phenomena inherent to CCD imaging device
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.
In this case, change the angle of the camera so that
such strong light does not enter the camera through
the lens.
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.
