Abstract:
An apparatus for retrieving moving image to retrieve pre-determined moving image from object moving image, comprising:first extracting means for extracting the information of the feature quantity of each frame from said pre-determined moving image; second extracting means for extracting the information of the unique identification created by arranging one or more physical quantity of said information of the feature quantity, extracted by said first extracting means, on a time axis; retrieving means for retrieving a position of said pre-determined moving image on said time axis from said object moving image by comparing the arrangement of said information of the unique identification, extracted by said second extracting means, with that of the information of the unique identification prepared in accordance with said object moving image; detecting means for detecting cut points of the moving image from said pre-determined moving image and dividing said pre-determined moving image into a plurality of shots at each of the cut points; and judging means for judging whether said pre-determined moving image is compressed or uncompressed moving image data; wherein said first extracting means includes; first uncompression extracting means for extracting the information of the feature quantity of each frame from the uncompressed moving image data; and first compression extracting means for extracting the DCT (Discrete Cosine Transform) coefficients of each frame as the information of the feature quantity from the compressed moving image data; said detecting means includes; uncompression detecting means for detecting cut points of the moving image from the uncompressed moving image data and dividing said predetermined moving image into a plurality of shots at each of the cut points; and compression detecting means for detecting cut points of the moving image from the compressed moving image data and dividing said pre-determined moving image into a plurality of shots at each of the cut points; and said second extracting means includes; second uncompression extracting means for extracting the information of the unique identification to identify the moving image at each of the shots, divided by said uncompression detecting means, in accordance with said information of the feature quantity of moving image, extracted by said first uncompression extracting means; and second compression extracting means for arranging at least one information of the feature quantity, extracted by said first compression extracting means, on the time axis at each of the shots, divided by said compression detecting means, and extracting the information of the unique identification to identify the moving image from the information of the feature quantity arranged on said time axis.
