Abstract
It is an object of this invention to detect a similar picture at high speed with high accuracy from a large-scale picture archive. Previously, a frame is extracted from each picture in a picture archive at fixed time intervals, an image feature quantity is extracted from each extracted frame, and the extracted image feature quantities are clustered, thereby constructing a clustered feature quantity database. A frames search section performs a similar frame search not only for a leading frame of a query picture but also for a subsequent frame, by using the database. A search result integration section checks whether there is a sequence across a plurality of search results and outputs, as a picture similar to the query picture, a segment which is confirmed to be continuous for a certain length or more.
