Abstract

A method of storing video information, i.e., video data, transmitted to a control unit via a plurality of communication paths is disclosed. The method comprises the steps of (a) providing a first memory means in the respective communication paths connected to the control unit, and (b) storing the video information in the first memory means. The video information is transmitted to the first memory means via the respective communication paths. The first memory means acts as a buffer system allowing the storage of multiple image frames. The method further comprises the steps of (c) reading the video data stored in the first memory means in units of a predetermined quantity; and (d) storing the units of read video information in a second memory means.

Claims

1. A method of storing video information transmitted to a control unit via a plurality of communication paths, comprising:

(a) providing a first memory means in the communication paths connected to the control unit; and

(b) storing the video information in the first memory means, wherein the video information is transmitted to the first memory means via the communication path; and

(c) reading the video information stored in the first memory means; and

(d) storing the read video information in a second memory means.

2. The method as in claim 1, wherein the step (c) is performed by reading the video information in quantities of first units

3. The method as in claim 2, wherein each first unit is a predetermined number of image frames.

4. The method as in claim 2, wherein the video information is stored in the second memory in quantities of the first units.

5. The method as in claim 2, further comprising a step of;

allocating addresses to the video information read from the first memory means.

6. The method as in claim 1, wherein the second memory means comprises a hard disk drive.

7. The method as in claim 1, further comprising steps of:

storing the video information read from the first memory means in a third memory means; and

reading the video information stored in the third memory means in quantities of second units; and

wherein the read video information in step (d) comprises the video information in quantities of second units read from the third memory means.

8. The method as in claim 7, wherein each second unit is a predetermined number of image frames.

9. The method as in claim 8, further comprising determining the predetermined number of image frames so as to correspond to a storage region of the second memory means.

10. The method as in claim 9, wherein the second memory means comprises a hard disk drive, and

wherein the third memory means comprises RAM.

11. The method as in claim 1, wherein the video information represents images captured by a plurality of cameras.

12. The method as in claim 11, wherein the video information comprises a first video information of an image in front of an automobile, and a second video information of an image of an interior of the automobile.

13. The method as in claim 1, further comprising the step of;

compressing the video information.

14. The method as in claim 13, further comprising the steps of;

reading the compressed video information stored in the second memory means, and

decompressing the read video information.

15. The method as in claim 14, further comprising displaying the uncompressed video information on display means.

16. The method as in claim 1, further comprising reading out the video information stored in the second memory means and displaying the read video information on display means.

17. A system for storing video information comprising:

a control unit; and

a plurality of communication paths connected to the control unit; and

a plurality of first memory means; and

a second memory means connected to the control unit;

wherein each of the first memory means are disposed within at least one of the communication paths, and

wherein the first memory means are arranged and constructed to store video information that is received by the first memory means via the communication paths; and

wherein the second memory means are arranged and constructed to store the video information read from the first memory means via the control unit; and

wherein the control unit is arranged and constructed to read the video information stored in the first memory means and to transmit the read video information to the second memory means.

18. A system as in claim 17, wherein the control unit is arranged and constructed to read the video information from the first memory means in quantities of first units.

19. The system as in claim 18, wherein each first unit is a predetermined number of image frames.

20. The system as in claim 17, wherein the control unit is arranged and constructed to allocate addresses to the video information read from the first memory means.

21. The system as in claim 17, wherein the second memory means comprises a hard disk drive.

22. The system as in claim 17, further comprising:

a third memory means arranged and constructed to store the video information read from the first memory means; and

wherein the control unit is further arranged and constructed to read the video information stored in the third memory means in quantities of second units and to store the read video information from the third memory means in the second memory means.

23. The system as in claim 22, wherein each second unit is a predetermined number of image frames.

24. The system as in claim 23, wherein the control unit is arranged and constructed to determine the predetermined number of image frames so as to correspond to a storage region of the second memory means.

25. The system as in claim 24, wherein the second memory means comprises a hard disk drive and a third memory means comprises RAM.

26. The system as in claim 17, wherein the video information represents images captured by a plurality of cameras.

27. The system as in claim 26, wherein the video information comprises a first video information of an image in front of an automobile and a second video information of an image of an interior of the automobile.

28. The system as in claim 17, further comprising compression means disposed in the communication paths and arranged and constructed to compress the video information before the video information is received by the first memory means.

29. The system as in claim 28, further comprising decompression means arranged and constructed to uncompress the video information, wherein the control unit is arranged and constructed to read out compressed video information stored in the second memory means and to uncompress the read video information by the decompression means.

30. The system as in claim 29, further comprising display means arranged and constructed to display the uncompressed video information.

31. The system as in claim 17, wherein the control unit is arranged and constructed to read the video information stored in the second memory means and to display the read video information on display means.
