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 generate a second image based on a first image derived from an image captured by an image capturing device, the first image having a first resolution and 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 having the second resolution;

an information generating section configured to generate 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; and

an output section for generating an output state based on the position of the object in the third image .

2. An image signal processing system according to claim 1, wherein the third image is the first image.

3. An image signal processing system according to claim 1, wherein the resolution of the third image is the same as the first resolution.

4. An image signal processing system according to claim 1, further comprising one or more image capturing devices configured to capture the image.

5. An image signal processing system according to claim 1, wherein the image capturing device is a camera device.

6. An image signal processing system according to claim 1, wherein the output state includes information of the position of the object in the third image.

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

8. An image signal processing method comprising:

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

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

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

outputting an output state based on the position of the object in the third image for display.

9. An image signal processing method according to claim 8, wherein the third image is the first image.

10. An image signal processing method according to claim 8, wherein the resolution of the third image is the same as the first resolution.

11. An image signal processing method according to claim 8, further comprising capturing the first image.

12. An image signal processing method according to claim 11, wherein the first image is captured by one or more image capturing devices.

13. An image signal processing method according to claim 8, wherein the output state includes information of the position of the object in the third image.

14. An image signal processing method according to claim 8, wherein the output state includes a mark indicating the position of the object in the third image.

15. An image signal processing system comprising:

circuitry configured to;

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

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

generate 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; and

generate an output state based on the position of the object in the third image.

16. An image signal processing system according to claim 15, wherein the third image is the first image.

17. An image signal processing system according to claim 15, wherein the resolution of the third image is the same as the first resolution.

18. An image signal processing system according to claim 15, further comprising one or more image capturing devices configured to capture the image.

19. An image signal processing system according to claim 15, wherein the image capturing device is a camera device.

20. An image signal processing system according to claim 15, wherein the output state includes information of the position of the object in the third image.

21. An image signal processing system according to claim 15, wherein the output state includes a mark indicating the position of the object in the third image.
