Provided is a method and apparatus for detecting a film source using Frequency Transform. The method includes: performing predetermined Frequency Transform on a predetermined reference pattern and storing a pattern of magnitudes of the resultant values of the predetermined Frequency Transform; receiving a predetermined number of similarity values that are measured between the same types of adjacent two fields of video including interlaced fields; performing predetermined Frequency Transform on the similarity values; and comparing magnitudes of the similarity values with the magnitudes of the predetermined reference pattern, and if differences between the magnitudes of the similarity values and the magnitudes of the predetermined reference pattern are within a predetermined range, determining the video as the film source. |
