Claim:
1. A swallowable in-vivo imaging device, comprising: an imager for capturing image frames; a battery to power said in-vivo imaging device; a frame counter for counting image frames captured by said imager; an indicator configured to indicate a warning prior to swallowing of the in-vivo imaging device, wherein the indicator is at least one of a light source to issue a visual signal and a loudspeaker to issue an audio signal; a memory; and a processor configured to register captured image frames and cause said indicator to indicate the warning when a number of image frames counted by the frame counter prior to swallowing of the in-vivo imaging device exceeds a critical number of frames; wherein the critical number of frames is calculated based on a lifetime of the battery, an amount of time necessary to complete imaging of a required length of a gastrointestinal tract, and an image frame capture rate of the imager, and wherein a difference between the lifetime of the battery and a division of the critical number of frames by the image frame capture rate is greater than the amount of time necessary to complete imaging of the required length of the gastrointestinal tract.
