1. A shutter speed control method for controlling a shutter speed of a stereoscopical imaging apparatus which images an object from a plurality of different directions, the method comprising the steps of:

  • dividing the image of the object produced by the imaging apparatus into a plurality of zones;

    averaging a brightness for each zone to produce an average brightness value for each zone;

    for each zone, determining a zone correction level with respect to a present shutter speed of the imaging apparatus, based upon the average brightness value for the zone;

    producing a shutter speed correction level based upon the determined zone correction levels; and

    correcting said present shutter speed of the imaging apparatus based on the shutter speed correction level, to thereby obtain a new shutter speed for the imaging apparatus.
