Abstract:
A telecine signal conversion method for converting an interlaced scan telecine signal generated by 2-3 pull-down system for converting a picture of first frame into an interlaced signal of first and second fields and for converting a picture of second frame following said first frame into an interlaced signal of third, fourth and fifth fields, into a progressively scanned telecine signal,said telecine signal conversion method comprises steps of:detecting a pull-down phase of said interlaced scan telecine signal;specifying said first and second fields based on said detected pull-down phase, composing picture signals of said specified first and second fields and generating progressively scanned telecine signals from said picture signals of said first and second frames; andspecifying said third and fourth fields based on said detected pull-down phase, composing picture signals of said specified third and fourth fields and generating progressively scanned telecine signals from said picture signals of said third, fourth and fifth frames;wherein said detecting step of detecting a pull-down phase of said interlaced scan telecine signal comprises a step of detecting said pull-down phase based on a time code value of said interlaced scan telecine signal.
