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:
“When lilacs last in the dooryard bloomed
And the great star early drooped in the western sky in the night,
I mourned, and yet shall mourn with ever-returning spring.
Ever-returning spring, trinity sure to me you bring,
Lilac blooming perennial and drooping star in the west,
And thought of him I love.”
—Walt Whitman (1819–1892)
“... Live!/and have your blooming in the noise of the whirlwind.”
—Gwendolyn Brooks (b. 1917)
“‘It’s the same the whole world over;
It’s the poor that gets the blame,
It’s the rich that gets the pleasure.
Isn’t it a blooming shame?’”
—Unknown. She Was Poor but She Was Honest (l. 37–40)
