1. A moving body image extraction apparatus comprising:
- a first calculation section for calculating difference intensity relating to a background portion or other frame with respect to a plurality of frames;
a summing section for summing the difference intensities of the plurality of frames calculated by said first calculation section;
a second calculation section for calculating a value by dividing the difference intensity of an arbitrary frame of the plurality of frames by the difference intensity for the plurality of frames summed by said summing section; and
a first output section for outputting an extracted image of a moving body in the arbitrary frame based on the value calculated by said second calculation section.

Abstract
A moving body image extraction apparatus calculates difference intensity relating to a background portion with respect to a plurality of frame of continuous shoot, calculates a value by dividing difference intensity of an arbitrary frame of the plurality of frames by summed difference intensity for the plurality of frames, outputs an extracted image of a moving body in the arbitrary frame based on the calculated value.
