Abstract

An image capture, conversion, compression, storage and transmission system provides a data signal representing the image in a format and protocol capable of being transmitted over any of a plurality of readily available transmission systems and received by readily available, standard equipment receiving stations. The system is adapted to be installed in a standard cellular phone configuration, providing a portable, hand held, wireless transmission system for transmitting video image signals to a remote receiving station.

Claims

1. An image processing system for capturing a visual image and transmitting it to a remote receiving station, the image processing system being adapted for use in combination with a hand held cellular telephone powered by a removable, rechargeable battery which is removably mounted in a battery carrier in the telephone, the system comprising:

a. a housing adapted to be mounted in the battery carrier in the telephone, in lieu of the battery;

b. a battery carrier in the housing adapted for receiving the removable, rechargeable battery;

c. a data receiving and processing system in the housing and adapted for producing an output data signal in a format transmittable over the telephone system;

d. a power transfer circuit for powering the data receiving and processing system and the cellular telephone directly from the battery in the battery carrier in the housing;

e. a connector for connecting the data receiving and processing system directly to the telephone for inputting the output data signal thereto for telephonic transmission; and

f. an adapter associated with the data receiving and processing system for selectively transmitting the output data signal over a land line telephone system.

2. The system of claim 1, further including an isolation circuit for isolating the data receiving and processing system whenever the land line transmission is in use.

3. The system of claim 1, wherein the image is transmitted in a full color, high resolution 640×

480 pixel format.

4. The system of claim 1, further including apparatus for transmitting the captured image selectively in a high, medium or low resolution mode.

5. The system of claim 1, further including a compression device for compressing the data representing the captured image.

6. The system of claim 5, wherein the compression device utilizes a JPEG compression algorithm.

7. The system of claim 5, wherein the compression device utilizes a wavelet compression algorithm.

8. The system of claim 1, further including a video image storage memory for storing the image after capture and prior to transmission.

9. The system of claim 8, further including an addressing device for addressing the video image on a selected pixel-by-pixel basis in the storage memory.

10. The system of claim 8, further including an addressing device for addressing the video image in pixel form in the storage memory selectively by:

a. row or column access;

b. decimation; and

c. non-linear, sequential pixel access.

11. The system of claim 1, further including a remote access subsystem whereby the system may be operated via operator input from a remote location.

12. The system of claim 11, wherein said remote access is via a wired communication system.

13. The system of claim 11, wherein said remote access is via a landline telephone communication system.

14. The system of claim 11, wherein said remote access is via a wireless communication system.

15. The system of claim 11, wherein said remote access is via a cellular telephone communication system.

16. The system of claim 11, wherein said remote access is adapted for downloading firmware to the system.

17. The system of claim 2, further including a detection circuit for detecting the presence of a land line telephone hook up.

18. The system of claim 17, wherein the isolation circuit is automatically activated upon detection of the presence of a land line telephone hook up.

19. The system of claim 17, wherein the detection circuit is adapted for selecting either a land line protocol or a cellular telephone protocol based on the detection of a land line telephone hook up.

20. The system of claim 1, wherein the data receiving and processing system further comprises a storage device for storing the image data input signals for recall and transmission on an other than real time basis

21. An image processing system for capturing a visual image and transmitting it to a remote receiving station, the image processing system being adapted for use in combination with a hand held cellular telephone powered by a removable, rechargeable battery which is removably mounted in a battery carrier in the telephone, the system comprising:

a. a housing adapted to be mounted in the battery carrier in the telephone, in lieu of the battery;

b. a battery carrier in the housing adapted for receiving the removable, rechargeable battery;

c. a data receiving and processing system in the housing and adapted for producing an output data signal in a format transmittable over the telephone system;

d. a power transfer circuit for powering the data receiving and processing system and the cellular telephone directly from the battery in the battery carrier in the housing; and

e. a connector for connecting the data receiving and processing system directly to the telephone for inputting the output data signal thereto for telephonic transmission.

22. The image processing system of claim 21, further including a remote triggering device for capturing a video image data signal upon remote initiation.

24. The image processing system of claim 23, further including a data receiving port in the housing for accepting incoming data from a remote source.

25. The system of claim 23, the telephone further including a data port, wherein the system includes a cable and data port compatible connector for connecting the data receiving and processing system to the telephone.

26. The system of claim 23, further including means for selectively and alternatively connecting the system to a land line telephone system, whereby the output data signal may be transmitted over the land line telephone.

27. The system of claim 23, further including a remote initiation device for initiating the sending of the output data signal from the system to the telephone and for initiating transmission of the data by the telephone.

23. An image processing system for capturing a visual image and transmitting it to a remote receiving station, the image processing system being adapted for use in combination with a hand held cellular telephone powered by a removable, rechargeable battery which is removably mounted in a battery carrier in the telephone, the system comprising:

a. a housing adapted to be mounted in the battery carrier in the telephone, in lieu of the battery;

b. a battery carrier in the housing adapted for receiving the removable, rechargeable battery;

c. a data receiving and processing system in the housing and adapted for producing an output data signal in a format transmittable over the telephone system;

d. a power transfer circuit for powering the data receiving and processing system and the cellular telephone directly from the battery in the battery carrier in the housing; and
