    摘要: A low-cost motion-compensated picture signal scan conversion circuit ensuring high picture quality is to be provided. The circuit has a motion-adaptive first interpolation signal generator; a second motion-compensated interpolation signal generator; a motion vector detector; and a setting unit for checking the reliability of motion compensation by comparing signals from the second interpolation signal generator with signals on interlaced scanning lines, and setting the selection of signals from the first and second interpolation signal generators, wherein interlaced scanned signals are converted into progressive scanned signals by setting the threshold so that the threshold become smaller with an increase in the number of re-searched blocks in the detection of motion vectors.

    摘要: A motion information signal generating circuit comprises a motion detecting circuit for detecting a piece of motion information from a digitized television signal; a temporal-spatial signal processing circuit for expanding a signal representing the so detected motion information both in time and space and a noise eliminator circuit connected between the motion detecting circuit and the temporal-spatial signal processing circuit. The noise eliminator circuit has at least one 1H memory to detect the correlation between the motion information signals pertaining to two adjacent picture elements which are one horizontal sweep line part, and for instance, the motion information signal of a smaller data quantity is selected, thereby preventing appearance of a false motion signal which would be caused by a noise of increased amplitude.
