Patent ID: 7512251

Claim:
A monitoring system to which camera images shot by a plurality of cameras installed to a moving body are input, comprising: a parameter storage section for storing a plurality of image synthesis parameters each expressing correspondence between camera images and a synthetic image and a plurality of detection parameters each defining specification of moving object detection; a parameter selection section for selecting each one from the plurality of image synthesis parameters and the plurality of detection parameters which are stored in the parameter storage section; an image synthesis section for generating a synthetic image showing a state of a monitoring region by synthesizing the camera images according to the image synthesis parameter selected by the parameter selection section; a display device for displaying the synthetic image generated by the image synthesis section; and a moving object detection section for detecting a moving in the synthetic image, based on the detection parameter selected by the parameter selection section, wherein the parameter selection section performs parameter selection according to a state of the moving body and taking account of a detection result by the moving object detection section, the parameter selection section performs parameter selection taking account of a currently selected image synthesis parameter the plurality of image synthesis parameters include weights for pixel values of the camera images, the weights for the pixel values being used by the image synthesis section for generating the synthetic image.
