Abstract
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.
Claims28
An in vivo camera system comprising:
- an imager having a variable frame capture rate for producing frames;
- at least one sensor for measuring a physical property relatable to the motion of said camera system;
- a data processor in communication with said sensor for determining a frame capture rate in response to output of said sensor;
- and
- a controller for providing said determined frame capture rate to said imager.
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.
A display system for displaying the output of an in vivo camera system, the display system comprising:
- a frame storage unit for storing frames of output of said camera system;
- an image processor for correlating frames of said output to determine the extent of their similarity and for generating a frame display rate therefrom, 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.
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.
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:
- measuring a physical quantity experienced by said camera system;
- converting said physical quantity to a velocity of said camera system;
- correlating said velocity with a predetermined frame capture rate;
- and
- communicating said predetermined capture rate to said imager.
A method for varying the frame display rate of a series of frames generated by an in vivo camera system, the method comprising the steps of:
- storing said frames in a storage device;
- correlating changes in the details of at least two frames;
- and
- communicating said required frame display rate to said storage device and a display unit.
