Apparatus and method for light control in an in-vivo imaging device

Abstract

A device and method for for example operating an in vivo imaging device wherein the illumination is operated at a certain rate or range of rates, and images are transmitted from the device.

1 . A method of operating an autonomous swallowable in-vivo imaging capsule, the method comprising: 
 illuminating a site and acquiring images using an imaging sensor within an in-vivo imaging capsule at a rate of from two to eight frames per second; and    transmitting the images from the imaging capsule.    
     
     
         2 . The method of  claim 1  comprising activating a light source for the illuminating step at a rate of from two to eight times per second.  
     
     
         3 . The method of  claim 1  comprising activating a plurality of light sources for the illuminating step.  
     
     
         4 . The method of  claim 1  comprising acquiring images using an imaging sensor at a rate of from about four frames per second.  
     
     
         5 . The method of  claim 1  comprising transmitting wirelessly.  
     
     
         6 . An autonomous swallowable in vivo imaging capsule comprising: 
 a light source;    an imaging sensor configured to acquire images at a rate of from two to eight frames per second; and    a transmitter.    
     
     
         7 . The capsule of  claim 6  comprising more than one light source.  
     
     
         8 . The capsule of  claim 7  wherein the imaging sensor is configured to acquire images at a rate of about four frames per second.  
     
     
         9 . The capsule of  claim 8  wherein the transmitter is wireless.  
     
     
         10 . The capsule of  claim 9  wherein the light source includes an LED.
