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, andwherein 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.

Abstract
A device and system for monitoring the status of a battery in an in-vivo imaging device, prior to use of the in-vivo imaging device. The device may include a frame counter for counting the number of frames captured and may include monitoring the voltage of the battery. A warning signal is generated if it is determined that the battery is faulty prior to use. The warning signal can be generated by the device and/or by a receiver which receives data from the in-vivo imaging device and/or a by workstation which receives the data from the receiver.

4. An in-vivo imaging system, comprising an in-vivo imaging device and a receiver, the in-vivo imaging device being powered by a battery, the receiver and the in-vivo imaging device being separate physically non-connected members, the in-vivo imaging device comprising:
-
an imager for capturing image frames; a frame counter for counting a number of 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; and a transmitter for wirelessly transmitting at least the number of image frames captured by said imager; the receiver comprising; at least one antenna for receiving data transmitted by the in-vivo imaging device; a receiver memory for storing data received by the at least one antenna; a receiver data processor; and a receiver indicator configured for indicating the warning prior to swallowing of the in-vivo imaging device if a number of image frames counted by said frame counter 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. - View Dependent Claims (5, 6, 7, 8)
