Abstract

A device, system and method may enable the obtaining of in vivo images from within body lumens or cavities, such as images the gastrointestinal (GI) tract, where the data such as image data is typically transmitted or otherwise sent to a receiving system. The data transmitted, including, for example, image information, is compressed.

Claims

1. An in-vivo device comprising:

a sensor; and

a data compression unit.

2. The in-vivo device of claim 1, wherein the sensor is an imager.

3. The in-vivo device of claim 2, wherein the imager includes a CMOS.

4. The in-vivo device of claim 2, wherein the data compression unit is configured to accept image data from the imager and compress the image data.

5. The in-vivo device of claim 2, wherein the data compression unit is configured to accept image data from the imager in units of one frame and compress the image data in units of one frame.

6. The in-vivo device of claim 1 comprising a light source.

7. The in-vivo device of claim 1, wherein the data compression unit includes JPEG compression capability.

8. The in-vivo device of claim 1, wherein the data compression unit includes MPEG compression capability.

9. The in-vivo device of claim 1, wherein the in-vivo device is a swallowable capsule.

10. The in-vivo device of claim 1, wherein the in-vivo device is configured for imaging the gastrointestinal tract.

11. The in-vivo device of claim 1, comprising an RF transmitter.

12. The in-vivo device of claim 11, wherein the data compression unit provides compressed data to the transmitter.

13. A method of operating an in-vivo device including a sensor, the method comprising:

accepting data from the sensor; and

compressing the data to form compressed data.

14. The method of claim 13, comprising transmitting the compressed data.

15. The method of claim 13, comprising transmitting the compressed data via RF channel.

16. The method of claim 13, wherein the sensor includes an imager.

17. The method of claim 13, wherein the sensor includes a CMOS.

18. The method of claim 13, wherein the data accepted from the sensor is image data.

19. The method of claim 16, comprising:

accepting image data from the sensor in units of one frame; and

compressing the image data in units of one frame.

20. The method of claim 13, comprising compressing the data in a JPEG format.

21. The method of claim 13, comprising compressing the data in an MPEG format.

22. The method of claim 13, wherein the in-vivo device is a swallowable capsule.

23. The method of claim 13, comprising imaging the gastrointestinal tract.

24. The method of claim 13, comprising decompressing the data.

25. The method of claim 13, comprising displaying data as image data.

26. An in-vivo device comprising:
