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 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 is 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.
