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:
“I have enjoyed greatly the second blooming that comes when you finish the life of the emotions and of personal relations; and suddenly you find—at the age of fifty, say—that a whole new life has opened before you, filled with things you can think about, study, or read about.... It is as if a fresh sap of ideas and thoughts was rising in you.”
—Agatha Christie (1891–1976)
“... Live!/and have your blooming in the noise of the whirlwind.”
—Gwendolyn Brooks (b. 1917)
“Then cut down the trees when lumber grown,
And there’s your pristine earth all freed
From lovely blooming but wasteful weed
And ready again for the grass to own.”
—Robert Frost (1874–1963)
