1. An integrated image surveillance system, comprising: a first camera for capturing a first image of an area from a first viewpoint, wherein the first image is a static, large-coverage image of the area; a second camera for capturing a second image of the area from a second viewpoint displaced from the first viewpoint, wherein the second image is a dynamic, small-coverage image of the area, and the second image and the first image have a first overlap region; an image processing device, comprising: a first defining component, configured to define a first set of feature points in the first image and a second set of feature points in the second image, wherein the first set of feature points and the second set of feature points have a first registration relation, and the first registration relation further defines a first registration function for the first image and the second image; a first synthesis component, configured to integrate the first image and the second image according to the first registration function to form a third image, wherein, upon overlapping of the first image and the second image, data of the second image are shown in the third image; and a second defining component, configured to define the first image into first set of image points each having a first image chromaticity, the second image into second set of image points each having a second image chromaticity, and the third image into third set of image points each having a third image chromaticity; an adjusting component, configured to adjust discontinuous image chromaticity in the third image on two sides of a seam between the first image and the second image; a transforming component, configured to transform the third image synthesized from the first image and the second image from a two-dimensional image to a three-dimensional image for better spatial perception; and a display device for displaying the third image.
