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.

Abstract: A system and method for classification of images of an image stream includes receiving an image stream of unclassified images, for example produced by an in-vivo imaging device, and adapting an initial classification algorithm to classify images to groups based on at least a subset of the received image stream of unclassified images.
