Abstract
A specific frame is selected from a plurality of frames of moving image data, and an initial contour corresponding to an extraction target is generated in the selected frame. The initial contour is converged to the contour of the extraction target. An initial contour corresponding to the extraction target is set in an other frame on the basis of the result of the convergence. Contour convergence to the contour of the extraction target is effected on the basis of the set initial contour. As the other frame, frames preceding and subsequent to the selected frame with respect to time can be set.
