Abstract
An inter-field pull-down pattern detecting circuit determines whether an input video signal is a first pull-down signal or a second pull-down signal, on the basis of input plug information and a pattern of the consecutive inter-field correlation levels, obtained from an inter-field correlation determination circuit. A counter counts the number of times the pattern detecting circuit determines that the input video signal is the first pull-down signal. The counter is reset to '0' when the input video signal is determined to be other than the first and second pull-down signals. When the count of the counter exceeds a preset value, the input video signal is finally determined to be the first pull-down signal.
