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.

1. An in vivo camera system comprising: an imager having a variable frame capture rate for producing frames; a storage device for storing frames captured by said imager; an image processor for calculating the required frame capture rate from at least two frames; and a controller for providing said calculated frame capture rate to said imager. 2. An in vivo camera system according to claim 1 further comprising a display system comprising: a frame storage unit for storing at least two frames of output of said camera system; an image processor for correlating at least two frames of said output to determine the extent of their similarity and for generating a frame display rate correlated with said similarity, wherein said frame display rate is slower when said frames are generally different and faster when said frames are generally similar; and a display unit for displaying said frames received from said frame storage at said frame display rate. 3. A method for varying the frame capture rate of a series of frames generated by an in vivo camera system, the system comprising an imager, the method comprising the steps of: storing said frames in a storage device; correlating changes in the details of at least two frames; changing said frame capture rate to a predetermined frame capture rate according to the degree of change between said at least two frames; and communicating said required frame capture rate to said imager. 4. A method according to claim 3 wherein said at least two frames are consecutive frames. 5. A method according to claim 3 wherein said at least two flames are non-consecutive frames.
