In television, picture line-up generation equipment (PLUGE or pluge) is equipment used to generate greyscale test patterns in order to adjust the black level and contrast of a picture monitor. Various PLUGE patterns can be generated, the most common consisting of three vertical bars of super-black, normal black, and near-black and two rectangles of mid-gray and white. These three PLUGE pulses are included in the SMPTE color bars (at the bottom and near the right) used for NTSC, PAL, and SÉCAM.
Famous quotes containing the words picture, generation and/or equipment:
“He is no mystic, either, more than Newton or Arkwright or Davy, and tolerates none. Not one obscure line, or half line, did he ever write. His meaning lies plain as the daylight.... It has the distinctness of picture to his mind, and he tells us only what he sees printed in largest English type upon the face of things.”
—Henry David Thoreau (1817–1862)
“We were that generation called “silent,” but we were silent neither, as some thought, because we shared the period’s official optimism nor, as others thought, because we feared its official repression. We were silent because the exhilaration of social action seemed to many of us just one more way of escaping the personal, of masking for a while that dread of the meaningless which was man’s fate.”
—Joan Didion (b. 1935)
“At the heart of the educational process lies the child. No advances in policy, no acquisition of new equipment have their desired effect unless they are in harmony with the child, unless they are fundamentally acceptable to him.”
—Central Advisory Council for Education. Children and Their Primary Schools (Plowden Report)
