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 processing system comprising:

an image capturing section configured to capture a first image having a first resolution;

a low resolution image generating section configured to generate a second image based on the first image;

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

a display control section configured to cause a display of an annotation mark on a third image based on a position of the object detected in the second image.

2. The image processing system of claim 1, wherein the second image has a second resolution lower than the first resolution.

3. The image processing system of claim 2, wherein the third image has a resolution higher than the second resolution.

4. The image processing system of claim 2, wherein the third image has the same resolution as the first image.

5. The image processing system of claim 1, further comprising a recording section configured to record the first image with information related to the captured first image.

6. The image processing system of claim 5, wherein the information related to the captured first image includes at least one of an identification of the image capturing section, a record date on which the first image is recorded and a format in which the first image is recorded.

7. The image processing system of claim 1, wherein the object detection section is configured to detect a moving object in the second image.

8. The image processing system of claim 1, wherein the annotation mark is a frame locating the position of the object.

9. The image processing system of claim 8, wherein the frame surrounds the object in the second image.

10. An image processing apparatus comprising:

a low resolution image generating section configured to generate a second image based on a first image;

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

a display control section configured to cause a display of an annotation mark on a third image based on a position of the object detected in the second image.

11. The image processing apparatus of claim 10, wherein the first image is an image captured by an image capturing device coupled to the low resolution image generating section and further comprising a display device coupled by a network to the image processing apparatus to display the third image with the annotation mark.

12. An image processing method comprising:

capturing a first image having a first resolution;

generating a second image based on the first image;

detecting an object in the second image; and

causing a display of an annotation mark on a third image based on a position of the object detected in the second image.

13. The image processing method of claim 12, wherein the second image has a second resolution lower than the first resolution.

14. The image processing method of claim 13, wherein the third image has a resolution higher than the second resolution.

15. The image processing method of claim 13, wherein the third image has the same resolution as the first image.

16. The image processing method of claim 12, further comprising recording the first image with information related to the captured first image.

17. The image processing method of claim 16, wherein the information related to the captured first image includes at least one of an identification of an image capturing device which captures the first image, a record date on which the first image is recorded and a format in which the first image is recorded.

18. The image processing method of claim 12, wherein the object that is detected in the second image is a moving object.

19. The image processing method of claim 12, wherein the annotation mark is a frame locating the position of the object.

20. The image processing method of claim 19, wherein the frame surrounds the object in the second image.
