Abstract: A field sequence detector determines the field sequence of a series of fields of video by assessing the vertical frequency content of hypothetical de-interlaced images. Hypothetical images are formed from a currently processed field and an adjacent (e.g. previous or next) field. If the vertical frequency content is relatively high (e.g. above ½ the Nyquist frequency for the image), the hypothetical image is assessed to be formed of improperly interlaced fields, belonging to different frames. If the frequency content is relatively low, the hypothetical image is assessed to be properly assembled from fields of the same frame. The field sequence in the series of fields may be detected from the assessed frequency content for several of said series of fields. Known field sequence, such as 3:2 pull-down, 2:2 pull down, and more generally m:n:l:k pull-down sequences.
