ABSTRACT:
A method may be provided for setting an average picture level. This may include setting an average picture level with a fixed number of steps based on a pre-determined gray level range, deriving a low brightness intensifying coefficient, deriving a high brightness intensifying coefficient, deriving a first constant representing an average increase rate of brightness, and calculating a number of sustain pulses corresponding to a gray level of a video signal currently inputted based on the derived low brightness intensifying coefficient, the derived high brightness intensifying coefficient and the derived first constant.
