PPROBLEM TO BE SOLVED: To detect an effective image feature quantity from a time-space image to which information about both a time and a space is added. PSOLUTION: An apparatus 1 for detecting feature quantities of time-space images has a data input means 100 for inputting time-space images and storing the time-space images in a storage means 110, a matrix analysis means 120 for calculating and creating a matrix for each image frame through temporal differentiation and spatial differentiation, obtaining a plurality of pairs of eigenvalues and eigenvectors by analyzing the matrix as an eigenvalue problem, and selecting the pair of the largest eigenvalue and the eigenvector corresponding to the eigenvalue from among the plurality of pairs obtained, and a display means 130 for displaying the largest eigenvalue and the corresponding eigenvector selected as edge images about a time and a space.
