IPC SYSTEM FOR MINIMIZING PICTURE BREAKS AT THE TIME OF SCENE CHANGE BETWEEN FIELDS OF INTERLACED VIDEO SIGNALS

摘要

The IPC system for minimizing the screen cracking that can occur during the transitions between the fields of the interlaced video signal is disclosed. IPC system is converted to sunsa video signal by using the IPC mechanism other than the de-telecine module and the interlaced scanning video signal of the de-telecine techniques for outputting converted into sunsa video signal using a telecine techniques de-interlaced video signal and outputting IPC module and the scene change detector for the conversion scene by detecting a scene change between the field outputs the determination result of the interlaced scanning video if the other whether the interlaced scanning video telecine of the interlaced scanning video signal, according to the determination result output from the scene change detector comprising: a selector for outputting a signal of the sunsa video signal output from the de-telecine module or the IPC module, the de-telecine module for a field belonging to the same frame with reference to the immediately prior field relative to the present field di tele It characterized in that it creeps. In addition, it may realize a perfect screen broken prevented by further comprising a buffer memory for storing temporarily the one field immediately after relative to the current field.
