Stage: PROBLEM TO BE SOLVED: To track a position of a target object in a three-dimensional space, in video image data including multiple element image (EI) groups in a row.SOLUTION: In an optical system 100, an image analysis apparatus 30 includes: an image reconstruction unit 31 which reconstructs an image by refocusing a depth position of a target object from the first EI group; a template selection unit 32 which selects an EI for template; a bright-spot representative spot specifying unit 33 and a bright spot tracking unit 34 for determining a representative spot of bright spots in the EI group and changes in position thereof; a bright spot labeling unit 35 which puts the same label as that of the representative spot of the bright spots in the template to the representative spot of the bright spot corresponding to the representative spot of the bright spots in the template in each EI; and a three-dimensional coordinate update unit 36 which sets coordinates of the target object in the reconstructed image in the three-dimensional space, to initial coordinates of the target object, updates XY-coordinates of the target object identified by the label on the basis of the changes in position of the representative spot of the bright spots with the same label in the second and subsequent EI groups, and updates Z-coordinates based on distances between the representative spots in adjacent EIs.SELECTED DRAWING: Figure 1 (Grant)
