Abstract

An image monitoring system includes a recorder that records an image captured by a camera via a network. The system is controlled to display the present image captured by the camera or a past image recorded on the recorder. A moving object is detected from the image captured by the camera, the detector including a resolution converter for generating an image with a resolution lower than the resolution of the image captured by the camera. A moving object is detected from the image generated by the resolution converter and positional information on the detected moving object is output. The positional information of the detected moving object is merged with the image captured by the camera on the basis of the positional information.

Claims

1. An image signal processing system comprising:

a low resolution image generating section configured to generate a second image based on a first image having a first resolution captured by an image capturing device, the second image having a second resolution lower than the first resolution;

an object detection section configured to detect an object in the second image; and

a position information generating section configured to generate position information representing a position of the object in a third image based on a position of the object in the second image, the third image having higher resolution than the second resolution,

wherein a result of the object detection in the second image is used to inform alarm information to a user.

2. An image signal processing system according to claim 1, wherein

the position information of the object in the third image is generated by converting position information of the object in the second image to a resolution corresponding to the resolution of third image.

3. An image signal processing system according to claim 1, wherein the third image is output with the position information of the object in the third image.

4. An image signal processing system according to claim 1, wherein the third image includes a mark indicating the position of the object in the third image and is displayed.

5. An image signal processing system according to claim 1, further comprising:

at least one image capturing device configured to capture the first image.

6. An image signal processing system according to claim 5, wherein the position information of the object in the third image is generated by converting position information of the object in the second image to a resolution corresponding to the resolution of the third image.

7. An image signal processing system according to claim 5, wherein the third image is output with the position information of the object in the third image.

8. An image signal processing system according to claim 5, wherein the third image includes a mark indicating the position of the object in the third image and is displayed.

9. An image signal processing method comprising:

generating a second image based on a first image having a first resolution captured by an image capturing device, the second image having a second resolution lower than the first resolution;

detecting an object in the second image; and

generating position information representing a position of the object in a third image based on a position of the object in the second image, the third image having higher resolution than the second resolution;

wherein a result of the object detection in the second image is used to inform alarm information to a user.

10. An image signal processing method according to claim 9, wherein the position information of the object in the third image is generated by converting position information of the object in the second image to a resolution corresponding to the resolution of third image.

11. An image signal processing method according to claim 9, wherein the third image is output with the position information of the object in the third image.

12. An image signal processing method according to claim 9, wherein the third image includes a mark indicating the position of the object in the third image and is displayed.

13. An image signal processing method according to claim 9, further comprising:

capturing the first image.

14. An image processing method according to claim 13, wherein the position information of the object in the third image is generated by converting position information of the object in the second image to a resolution corresponding to the resolution of third image.

15. An image signal processing method according to claim 13, wherein the third image is output with the position information of the object in the third image.

16. An image signal processing method according to claim 13, wherein the third image includes a mark indicating the position of the object in the third image and is displayed.

17. An image signal processing system comprising:

circuitry configured to;

generate a second image based on a first image having a first resolution captured by an image capturing device, the second image having a second resolution lower than the first resolution;

detect an object in the second image; and

generate position information representing a position of the object in a third image based on a position of the object in the second image, the third image having higher resolution than the second resolution;

wherein a result of the object detection in the second image is used to inform alarm information to a user.

18. An image signal processing system according to claim 17, further comprising:

at least one image capturing device configured to capture a first image.

19. An image signal processing system according to claim 18, wherein the position information of the object in the third image is generated by converting position information of the object in the second image to a resolution corresponding to the resolution of third image.

20. An image signal processing system according to claim 18, wherein the third image is output with the position information of the object in the third image.

21. An image signal processing system according to claim 18, wherein the third image includes a mark indicating the position of the object in the third image and is displayed.

22. An image signal processing system according to claim 17, wherein the position information of the object in the third image is generated by converting position information of the object in the second image to a resolution corresponding to the resolution of third image.

23. An image signal processing system according to claim 17, wherein the third image is output with the position information of the object in the third image.

24. An image signal processing system according to claim 17, wherein the third image includes a mark indicating the position of the object in the third image and is displayed.
