1. An image processing apparatus for calculating a distance between two moving objects contained in time series images which are captured at different sampling times, comprising:

  • an image-input unit which inputs said image including a background and a plurality of objects;

    a marker holding unit which records location information of a plurality of markers in said background;

    a moving object extract unit which extracts a plurality of moving objects;
