METHOD AND AN APPARATUS FOR DETECTING A MOVIE IMAGE USING FREQUENCY CONVERSION TO JUDGE WHETHER A RECEIVED IMAGE IS A MOVIE IMAGE USING A CHANGE PATTERN IN A FREQUENCY DOMAIN

摘要

The present invention relates to video frequency signal processings, and in particular, to the input picture of the method and apparatus for detecting in a frequency domain whether is directed toward about film image. Film image detection method of the invention, (a) are transformed into predetermined reference pattern by executing preset frequency, comprising: store the pattern of the amplitude portion of conversion value; (B) from the image of interlaced field, the similarity measurement of the similarity between two adjacent fields of the same type of predetermined quantity is received; (c) preset frequency conversion is executed to the similarity value received; If (d) the size partial value of the frequency conversion of similitude and comparing the amplitude portion of stored reference model, the step of being determined as film image by their value difference within a predetermined range and by image respectively. Method of the invention is, by carrying out frequency transformation to the affinity information comprising sad value, moving image can be effectively detected.
