Patent ID: 7974454

Claim:
A method for capsule camera control, the method comprising: (a) providing a light source with a first light source control to illuminate lumen walls; (b) receiving image data from an image sensor of a capsule camera to derive a first frame; (c) evaluating a motion metric, associated with the first frame and a previously captured frame, based on motion vectors, SAD, MSE, total variance, center of mass, count of pixels having large differences or count of zero-valued motion vectors; and (d) selecting an operation mode for next image data from a group comprising Capture Mode and Conservation Mode based on a profile of the motion metric, wherein the Capture Mode is selected if the profile indicates an amount of motion between the first frame and the previously captured frame exceeding a threshold and the Conservation Mode is selected otherwise, and wherein a current image data is buffered in substantially reduced resolution and/or substantially reduced size if the mode is the Conservation Mode; wherein steps (a) through (d) are performed inside a capsule camera.
