An image processing device includes: an image pickup unit, for forming an image of a target with an optical system, then taking the image using an image pickup device, and obtaining image information including the target; a target-point detecting unit, for detecting a target point where the target exists within a field as position information expressed by information unrelated to the position where the image pickup unit exists; and a relevant information generating unit, for obtaining relevant information representing the correlation between the position information detected by the target-point detecting unit and the direction where the image pickup unit takes an image of the target and/or camera coordinates on the basis of the view angle (i.e., for performing calibration). Thus, the position of the target existing within the three-dimensional field space within an image pickup region where an image of the target is taken by the image pickup unit, can be calculated.
