Abstract
A motion determining apparatus for detecting a motion of a partial picture of an input picture signal is disclosed, that comprises a first motion detecting portion for comparing a frame difference detected for the partial picture with a predetermined threshold value and determining that the partial picture has a motion when the frame difference is larger than the threshold value, a second motion detecting portion for comparing a frame difference detected for the partial picture with a predetermined threshold value, comparing a field difference detected for the partial picture with a predetermined threshold value, and determining that there is a motion of an artificial picture when the frame difference and the field difference are larger than the respective threshold values, and an output portion for forming motion determination data with determination data that is output from the first motion detecting portion and the second motion detecting portion.
