Abstract
A film mode video sequence detector for detecting video sequences converted from movie films in 30 Hz frame rate video resources comprises a video signal detecting means provided a mean of absolute difference (MAD) value of input video signal and a film mode condition generation signal considering a user threshold and still picture, making a decision whether the input signal is film mode, and transmitting the film mode condition generation signal, film mode departure signal, the threshold pass signal, and a clock which is generated on film mode condition; a condition generating means provided the MAD value and the condition generating signal from the video mode detecting means, making a decision whether the MAD value shows a pattern off film mode considering still picture, transmitting the film mode condition generating signal to the video signal detecting means; a mode converting means provided an input field decision signal, a screen transition generating signal, departure signal from video mode decision means, a threshold pass signal, and a generating film mode departure signal considering secreen transition; a video mode decision means film mode departure signal from the mode converting means, clock when the signal from the video signal detecting means is film mode; and a video mode decision means being provided a user threshold and a transmitting video mode generating signal.
