Patent ID: 8410974

Claim:
An image processing device, comprising: an actual trail image memory for storing an actual trail data group indicating absolute changes in position of a target object detected by echo signals obtained corresponding to detection signals transmitted while changing an azimuth direction of the transmission; a relative trail image memory for storing a relative trail data group indicating relative changes in position of the target object with respect to a transmission origin location of the detection signals; and a moving target object determination processing module for determining whether the target object detected with the detection signals is a moving target object based on the actual trail data group; wherein a relative trail of the target object is displayed along with the target object, the displayed relative trail being based on the relative trail data group; and wherein the target object determined to be the moving target object by the moving target object determination processing module is displayed so as to be distinguished from another target object with a relative trail substantially similar to that of the moving target object.
