Abstract
An information processing device for tracking the image of a tracking point within a moving image wherein contents, of multiple images which are continuous temporally, are discontinuous temporally, includes: a block-matching unit for performing block matching within the moving image, wherein a processed image and an image prior to the processed image are compared to determine the position of the tracking point within the processed image; an interpolation unit for performing interpolation processing wherein the position of the tracking point within an image not subjected to the block matching, which is an image before or after the processed image within the moving image, is determined as the position of the tracking point within the processed image; and a motion-vector calculating unit for obtaining the motion vector of the tracking point based on the position of the tracking point within the processed image determined by the block-matching unit or interpolation unit.
