    • A method of correcting picture steadiness errors (or film weave correction) in telecine scanning is proposed, in which, in a first step, at least one sample area of the picture contents of the video signal obtained by film scanning is determined by way of structure recognition, this sample area corresponding to a curvature in the picture contents. In a second step, it is checked, by way of comparison, whether the determined sample areas are recognizable in a search area of the sequential frame. In a third step, motion vector signals are generated when the sample areas are recognized again in the sequential frame, these motion vector signals defining the direction of motion and the extent of deviation of the position of the determined sample area from the position of the recognized sample area. In a fourth step, parameters of a transform function are determined by the motion vector signals. In a subsequent fifth step, motion vectors, which correspond to partial motions, are recognized and eliminated by comparing the transform function with the motion vectors. Steps four and five are performed several times, if necessary. In a sixth step, correction signals are derived by taking the temporal sequence of transform functions into account, and in a seventh step, these correction signals are applied to a control device, these correction signals correcting the stability errors in the picture signals.
    • 提出了一种在电视电影扫描中校正图像稳定性错误(或胶片编织校正)的方法,其中在第一步骤中,通过胶片扫描获得的视频信号的图像内容的至少一个采样区域由结构 识别,该样本区域对应于图像内容中的曲率。 在第二步骤中,通过比较来检查确定的采样区域是否在连续帧的搜索区域中被识别。 在第三步骤中,当在连续帧中再次识别采样区域时,产生运动矢量信号,这些运动矢量信号定义运动方向和确定的采样区域的位置与所识别的位置的偏差程度 样品区。 在第四步中,变换函数的参数由运动矢量信号确定。 在随后的第五步中,通过将变换函数与运动矢量进行比较来识别和消除对应于部分运动的运动矢量。 如果需要,执行第四步和第五步多次。 在第六步骤中,通过考虑变换函数的时间序列来导出校正信号,并且在第七步骤中,这些校正信号被施加到控制装置,这些校正信号校正图像信号中的稳定性误差。

    • In the transmission of a television signal containing a luminance signal between a transmitting station and a receiving station of a television system, the picture resolution at the receiving station is compatibly increased by: effecting planar prefiltering of the luminance signal at the transmitting station and a corresponding planar postfiltering of the luminance signal at the receiving station; effecting offset sampling or offset modulation of the luminance signal at the transmitting station and a corresponding sampling conversion or demodulation of the luminance signal at the receiving station; deriving an additional signal from the luminance signal for increasing picture resolution, reducing the amplitude of the additional signal at the transmitting station and transmitting the additional signal together with the original luminance signal to the receiving station; and increasing the amplitude of the additional signal at the receiving station to an extent corresponding to the reduction performed at the transmitting station.
    • 在传输包含电视系统的发送站和接收站之间的亮度信号的电视信号时,通过以下方式来兼容地增加接收站处的图像分辨率:在发送站处执行亮度信号的平面预过滤, 在接收站处对亮度信号进行平面后置滤波; 在发送站处进行亮度信号的偏移采样或偏移调制,以及对接收站处的亮度信号进行对应的采样转换或解调; 从亮度信号导出附加信号以增加图像分辨率,减小发射站处的附加信号的幅度,并将附加信号与原始亮度信号一起发送到接收站; 以及将所述接收站处的所述附加信号的幅度增大到对应于在所述发射台处执行的减小的程度。
