摘要： The present invention provides a movement correction frame count transformation apparatus for carrying out frame count transformation processing on a picture signal. In the apparatus, an input picture signal (S1) of interlaced scanning is converted into a signal (S2) of sequential scanning by an IP conversion unit (1). A movement detecting unit (3) detects movement detection signals (MD1 and MD2). A block unit movement vector searching unit (4) detects a block unit movement vector (BMV) by carrying out block matching processing. A movement vector correcting unit (5) carries out miniblock division processing to generate a movement vector (BV) if a movement correction error is equal to or greater than a threshold value. A pixel unit movement vector generating unit (6) generates a movement vector with a smallest error component between a frame signal of a current frame and a frame signal of an immediately preceding frame as a movement vector of a pixel. An MC interpolation frame signal generating unit (7) generates an interpolation frame in movement correction processing carried out by a median filter in order to produce a signal (S4) of sequential scanning as a result of frame count transformation based on movement correction.

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.
