Blooming
When a CCD exposure is long enough, eventually the electrons that collect in the "bins" in the brightest part of the image will overflow the bin, resulting in blooming. The structure of the CCD allows the electrons to flow more easily in one direction than another, resulting in vertical streaking.
Some anti-blooming features that can be built into a CCD reduce its sensitivity to light by using some of the pixel area for a drain structure. James M. Early developed a vertical anti-blooming drain that would not detract from the light collection area, so did not reduce light sensitivity.

Famous quotes containing the word blooming:
“My wife never quite forgets to put flowers in vases,
Bizarre prints in the most unusual places,
Give teas for poets, wear odoriferous furs.
An awful blooming is hers.”

It’s the poor that gets the blame,
It’s the rich that gets the pleasure.
Isn’t it a blooming shame?’”

Left blooming alone;
All her lovely companions
Are faded and gone;”
