Abstract

An image monitoring system includes: recording means for recording an image captured by a camera via a network; control means for controlling the system so as to display the present image captured by the camera or a past image recorded on the recording means on display means; and moving-object detecting means for detecting a moving object from the image captured by the camera; wherein the moving-object detecting means includes resolution conversion means for generating an image with a resolution lower than the resolution of the image captured by the camera, positional-information output means for detecting a moving object from the image generated by the resolution conversion means and outputting positional information on the detected moving object, and information merging means for merging the positional information of the moving object with the image captured by the camera on the basis of the positional information of the moving object output by the positional-information output means.

Claims

1. An image signal processing system comprising:

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

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

a position information generating section configured to process the second image to generate position information based on the second image, the position information representing a position of the object in the first image; and

an output for generating an output state based on the detected object.

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

the position information representing the position of the object is generated by converting position information representing a position of the object in the second image to a resolution corresponding to a third resolution, the third resolution being higher than the second resolution.

3. An image signal processing system according to claim 2, wherein the third resolution is the same as the first resolution.

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

5. An image signal processing system according to claim 1, wherein the output state includes a mark indicating the position of the object in the first image.

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

one or more image capturing devices configured to capture the first image.

7. An image signal processing system according to claim 6, wherein the position information of the object in an image having a third resolution is generated by converting position information of the object in the second image to a resolution corresponding to the third resolution, the third resolution being higher than the second resolution.

8. An image signal processing system according to claim 7, wherein the third resolution is same as the first resolution.

9. An image signal processing system according to claim 6, wherein the first image is output with the position information of the object in the first image.

10. An image signal processing system according to claim 6, wherein the output state comprises a mark indicating the position of the object in the first image.

11. An image signal processing system according to claim 6, wherein:

the image capturing device is a camera device.

12. An image signal processing method comprising:

receiving a first image having a first resolution and containing an object captured by an image capturing device spaced from the object and generating a second image based on the first image, the second image having a second resolution lower than the first resolution;

detecting the object in the second image having the second resolution;

processing the second image to generate position information based on the second image, the position information representing a position of the object in the first image; and

outputting an output state based on the detected object.

13. An image signal processing method according to claim 12, further comprising:

capturing the first image by one or more image capturing devices.

14. An image signal processing method according to claim 13, wherein the image capturing device is a camera device.

15. An image signal processing method according to claim 13, wherein the position information of the object in an image having a third resolution is generated by converting position information of the object in the second image to a resolution corresponding to the third resolution higher than the first resolution.

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

17. An image signal processing method according to claim 13, wherein the output state comprises a mark indicating the position of the object in the first image.

18. An image signal processing method according to claim 12, wherein the position information representing the position of the object is generated by converting position information representing a position of the object in the second image to a resolution corresponding to a third resolution higher than the first resolution.

19. An image signal processing method according to claim 18, wherein the third resolution is same as the first resolution.

20. An image signal processing method according to claim 12, wherein the first image is output with the position information of the object in the first image.

21. An image signal processing method according to claim 12, wherein the output state includes a mark indicating the position of the object in the first image.

22. An image signal processing system comprising:

circuitry configured to;

receive a first image having a first resolution and containing an object captured by an image capturing device spaced from the object, and generate a second image based on the first image, the second image having a second resolution lower than the first resolution;

detect the object in the second image having the second resolution;

process the second image to generate position information based on the second image, the position information representing a position of the object in the first image; and

output an output state based on the detected object.

23. An image signal processing system according to claim 22, further comprising one or more image capturing devices configured to capture the first image.
