Abstract

A first camera 12 having a fish-eye lens 13 and a second camera 14 having a fish-eye lens 15 are disposed with the respective fish-eye lenses faced with each other. An image pick-up range of the first camera 12 and an image pick-up range of the second camera 14 are partially overlapped, and only a relatively narrow area at the backside of each camera becomes a blind area. A processor 30 sets a frame F in the image pick-up area of the first camera 12 and the image pick-up area of the second camera 14 respectively corresponding to a set monitoring range. The image data within these frames F are taken out and distortions of the image due to the characteristics of the fish-eye lenses 13 and 15 are eliminated to obtain first and second transformed frame data. These transformed frame data are combined by an image combining unit 25, to obtain image data corresponding the monitoring range free from any gap. The combined image data is displayed in a monitor 8 through a PC 7.
