Claim:
1. An information processing apparatus, comprising: a communications unit adapted to receive image data from a stereo movie, the stereo movie including a sequence of stereo image frames, each stereo image frame including first image data and second image data taken at a respective time in the sequence, the first image data including a first image frame captured along a first line of sight of a scene containing a subject, and saved at a plurality of hierarchical image resolutions, the second image data including a second image frame captured along a second line of sight of the scene, and saved at a plurality of hierarchical image resolutions; a position information acquisition section adapted to compute three-dimensional position information of the subject within a scene by performing stereo matching between respective areas, each defined by a final target area, of the first image frame and the second image frame at a selected one of the plurality of hierarchical image resolutions and at time t(i),wherein the final target area and the selected one of the plurality of hierarchical image resolutions are produced in accordance with a process comprising: a depth image data production section adapted to update a depth image at time t(i) containing pixel values based on portions of the first and second image frames defined by the final target area region at the selected one of the plurality of hierarchical image resolutions.
