Abstract
A back camera 13B, left-side and right-side cameras 13L and 13R, and a front camera 13F are provided on an upper swiveling body 3. By converting viewpoints of camera images obtained by the cameras 13B, 13L, and 13R, individual over view images are generated and are combined with one another to form a surveillance panorama image disposed around a display character 21. The surveillance panorama image is displayed, together with a camera image, which is an image obtained by the front camera 13F, in an image display section 20a of a monitor 20. By appropriately operating switches SW1 through SW5 provided in an operation panel section 20b, a camera image which has not been converted into one of the individual over view images is displayed in an enlarged state.
