Patent ID: 8165374

Claim:
A method for capsule camera control, the method comprising: (a) providing a light source to illuminate lumen walls; (b) receiving image data corresponding to a current frame from image sensor; (c) evaluating a motion metric based on motion vectors, SAD, MSE, count of pixels having large differences, count of zero-valued motion vectors, or center of mass associated with a current sub-image corresponding to the current frame and a previous sub-image; (d) capturing a full-size and full-resolution frame if the motion metric exceeds a threshold; (e) applying a compression process to the full-size and full-resolution frame captured if the motion metric exceeds the threshold; wherein steps (a) through (e) are performed inside a capsule camera; and wherein the compression process includes adaptive intra/inter frame prediction and applies intra-frame prediction for selected full-size and full-resolution frames.
