    • PROBLEM TO BE SOLVED: To solve detection delay in video signals, where telops run from screen ends to one part of telecine video.
      SOLUTION: A differential relationship between a current field image (F(t)) and a field image (F(t-2)) two fields before is determined for each of a plurality of blocks BL into which a field is divided. Further, a field fringing section EG having a prescribed width is defined at least to one side of a periphery of each field, and a determination result of the video signal for a part corresponding to the field fringing section EG is set to obtain a non-telecine video signal regardless of determination for each block BL. Therefore, it is determined that a video signal is a non-telecine video signal even while content not subjected to telecine conversion appears at a screen end and passes through the field fringing section EG.

    • 要解决的问题:解决视频信号中的检测延迟,其中字幕从屏幕末端延伸到电视电影视频的一部分。 解决方案:对于分割为场的多个块BL中的每一个确定两个场之前的当前场图像(F(t))和场图像(F(t-2))之间的差分关系 。 此外,具有规定宽度的场边缘部分EG被限定在每个场的周边的至少一侧,并且用于与场边缘部分EG对应的部分的视频信号的确定结果被设置为获得非 - 电视电影视频信号,无论每个块BL的确定。 因此,即使没有进行电视电影转换的内容出现在屏幕端并通过场边缘部分EG,也确定视频信号是非电视电影视频信号。 版权所有(C)2010,JPO&INPIT
