ABSTRACT:
An information processing apparatus searches search target frame images in video data to find a frame image matching a search query frame image. An extractor extracts characteristic quantities expressing the characteristics of respective images. A reliability judge judges the reliability of the values of each characteristic quantity in a characteristic quantity group extracted from the search query frame. If certain characteristic quantity values in the search query frame are judged to be of low reliability, the converter converts those values into predetermined values. Values are similarly converted for all search target frames. A comparer compares the converted characteristic quantities in the search query frame to the converted characteristic quantities in all search target frames. On the basis of the comparisons, a decision unit then chooses a search solution frame that matches the search query frame. In so doing, search processing robustness with respect to data variance is improved.
