Moving image data comparison method, moving image data comparison program, moving image data comparison device

摘要

A method comprises extracting a picture type and size per picture frame from encoded first moving picture data, calculating a first characteristic quantity per picture frame and a first variation point indicating a variation point of the first characteristic quantity on the basis of the extracted picture type and size, extracting a picture type and size per picture frame from encoded second moving picture data, calculating a second characteristic quantity per picture frame and a second variation point indicating a variation point of the second characteristic quantity on the basis of the extracted picture type and size, and comparing the first characteristic quantity and variation point with the second characteristic quantity and variation point, and determining whether or not the first moving picture is similar to the second moving picture.
