发明名称 NOISE REDUCTION DEVICE IN DIGITAL IMAGE COMMUNICATION
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a method for reducing noise in the packet communication of digital image data. <P>SOLUTION: In the digital image communication of communicating the image data of an interlace scanning system by packets, in order to reduce the noise relating to a horizontal scanning line having a given horizontal scanning line number within a certain given field, transmitted successive packets are received (400). Then, in the case that part of the successive packets is absent (406), the absence packet part is interpolated (410). For the interpolation, horizontal scanning line data for the absence packet part are generated by using the data of at least one packet relating to the horizontal scanning lines (n-1, n+1) separated timewise from the horizontal scanning line (n) that the absence packet part is related to. <P>COPYRIGHT: (C)2003,JPO</p>
