1. A capsule camera apparatus, comprising:

  • a housing adapted to be swallowed;

    a light source within the housing;

    an archival storage device;

    a camera within the housing for capturing a first digital image and a second digital image of a scene illuminated by the light source;

    a motion detector within the housing comprising;

    a metric measurement module coupled to the first digital image and the second digital image measures a metric of a motion between the first digital image and the second digital image;

    a motion detection module coupled to the metric measurement module detects the motion based on the metric and a threshold; and

    a threshold update module coupled to the metric measurement module and the motion detection module updates the threshold; and

    a control circuit within the housing that designates the second digital image for further processing based on the motion detected by the motion detection module.
