VIDEO DATABASE RETRIEVAL/DISPLAY METHOD AND DEVICE THEREFOR AND STORAGE MEDIUM FOR STORING VIDEO DATABASE RETRIEVAL/DISPLAY PROGRAM

摘要

PROBLEM TO BE SOLVED: To attain a global point of view at the retrieval of a video database. SOLUTION: A video database 101 stores not only video data but also attribute values. A retrieving part 102 inputs a question, and retrieves suitable video data or attribute values from the video database 101 (a step 201). A transforming part 103 transforms the attribute value in the video database 101 into a pixel value, and prepares listed images (a step 202). In this case, when an attribute value at time (t) of a video whose identification numbers is (i) is defined as a(t, i), a pixel value v(t, i) is obtained by a transformation v(t, i) = f(a (t, i)) using a transformation function (f). A display part 104 displays the listed image prepared by the transforming part 103 (a step 203).
