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:
“It is terrible to destroy a person’s picture of himself in the interests of truth or some other abstraction.”
—Doris Lessing (b. 1919)
“An evil and adulterous generation asks for a sign, but no sign will be given to it except the sign of the prophet Jonah.”
—Bible: New Testament, Matthew 12:39.
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
