Abstract
60 fields of an interlace image (telecine image) after 32-pull down is input. The input images stored in field memories are read, and the grayscale difference (difference absolute value) between frames is computed by a pixel difference absolute value subtractor. The difference absolute value and five threshold values are compared by an absolute value difference comparator. A cumulative adder stores one field of comparison result. A flag information creation processing unit creates a flag information table for indicating whether a current field is a repeat field with noise or not, based on the information from the cumulative adder. A repeat field judgment unit detects a 32-pull down sequence from the flag information table, and detects whether the current field is a repeat field with noise or not, and so forth. A 32-transform control unit performs IP (Interlace to Progressive) conversion based on the detected repeat fields.
