System and method for in-vivo imaging
First Claim
1. A method for varying a frame capture rate of an in vivo imaging capsule, the method comprising:
- using a swallowable imaging capsule, capturing first in vivo images at a first frame capture rate;
measuring a physical quantity experienced by the imaging capsule;
wherein the physical quantity is one of acceleration, pressure, induced current or motion;
converting the physical quantity measurements to a velocity of the imaging capsule;
based on the velocity, determining a second frame capture rate; and
using the swallowable imaging capsule, capturing second in vivo images at the second frame capture rate.

Abstract
An in-vivo imaging device including a camera may include a frame storage device. Systems and methods which vary the frame capture rate of the camera and/or frame display rate of the display unit of in-vivo camera systems are discussed. The capture rate is varied based on for example, a physical quantity experienced by the camera system, or physical measurements related to the motion of the camera. Alternatively, the frame capture rate is varied based on comparative image processing of a plurality of frames. The frame display rate of the system may be varied based on comparative image processing of a multiplicity of frames. Both the frame capture and the frame display rates of such systems can be varied concurrently.
