摘要： Correlation of videos between fields is determined between a difference between an input interlaced signal and a signal that is delayed by one field with respect to the input interlaced signal. Correlation among N-1 sequential fields is compared with a predetermined pattern to determine whether the input interlaced signal is unquestionably a telecine-converted signal, whether it is unquestionably not a telecine-converted signal, or whether it cannot be said to be unquestionably a telecine-converted signal. If a determination of being unquestionably a telecine-converted signal is continued for a predetermined number or more of fields, an instruction signal, which instructs to perform inter-field interpolation on the input interlaced signal, is outputted.

摘要： A method for converting between relatively close field rates of perhaps 60 Hz and 59.94 Hz, monitors the phase difference between input and output field rates. Initially, output fields are created by synchronizing input fields. As the measured phase passes a threshold, the method switches to interpolation mode for a short, fixed interval and then returns to synchronization. The method offers much of the sharpness associated with simple synchronization but avoids the visible discontinuities of field drops or repeats.

摘要： A method of processing an input 60 field/second video signal generated by 3232 pulldown to produce an output video signal, comprises producing from the input signal a series of progressive scan format frames, each frame corresponding to a respective one of the input fields, and comparing blocks of pixels in each progressive scan frame with blocks of pixels in the following frame to derive motion vectors representing the motion of the content of respective blocks between frames. The motion vectors are utilized to monitor the field sequence of the input signal, and fields or frames of the output video signal are produced using input fields or progressive scan frames selected in dependence upon the field sequence of the input signal, at least some of the output fields or frames being produced by motion compensated temporal interpolation utilizing the motion vectors.

摘要： A video scan converter includes an input for receiving a video signal at a first scan rate, an output for providing a video signal at a second scan rate and a main path leading between the input and the output. The main path includes a scan line interpolation circuit and a time scale modification circuit which provide conventional two-dimensional scan conversion. A further path coupled to the main path dynamically alters the output of the scan line interpolation circuit in response to motion in the picture represented by the video signal, thus providing a three-dimensional scan conversion. The further path may be optional.

摘要： A combined de-interlacing and frame doubling system ( 114, 114′ and 114′) advantageously serves to de-interlace successive lines of Present Field Video data at twice the field rate to yield an output bit stream suitable for display on display device that utilizes progressive scanning.

At least one de-interlacing circuit (11401, 1140′1, 1140″) pulls at least two fields of video data from the memory mechanism at a rate of at least twice the field rate for performing a full de-interlacing function in half of a field period to generate the a progressive, frame doubled signal for receipt at the display device.
