Image retrieving apparatus performing retrieval based on coding information utilized for feature frame extraction or feature values of frames

摘要

An image retrieval information storing apparatus capable of extracting a featured frame adaptively in the process of retrieval includes a coding information reading unit reading prescribed coding information which will be information representing frame feature among coded image data, a frame feature value generating unit connected to the coding information reading unit and generating a frame feature value which is a numerical representation of the frame feature based on the coding information, and a frame feature value storing unit connected to the frame feature value generating unit and storing the frame feature value in correspondence with each frame of the image data.
