ABSTRACT:
A first correlation between a present field of an input video signal and a one-field preceding field, and a second correlation between the present field and a one-field succeeding field are detected. The first correlation and the second correlation are compared with each other, and the input video signal is determined as a telecine-converted video signal when either of the first correlation or the second correlation is larger than the other correlation.
