For [[Engineering:Television|televisions]] the '''picture line-up generation equipment''' ('''PLUGE''' or '''pluge''') is the greyscale test patterns used in order to adjust the [[Engineering:Black level|black level]] and [[Contrast (vision)|contrast]] of the 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 (sometimes these are measured in [[IRE (unit)|IRE]]). These three '''PLUGE pulses''' are included in the SMPTE color bars (at the bottom and near the right) used for [[Engineering:NTSC|NTSC]], [[Engineering:PAL|PAL]], and SÉCAM.
