A three-dimensional position posture relation detection unit detects a relation of relative three-dimensional position and posture between an image input unit and a target object using the image of the target object in a real space input from the image input unit. A difference comparison detection unit compares the detected position and posture of the target object and a value stored in a figuration information storage unit corresponding to a part of the target object so as to detect a difference between an actual position and posture of the input target object and stored figuration information of the target object. A figuration information management unit reflects a value of the detected difference on figuration information stored in the figuration information storage unit. A superposed image generation unit generates an image which is obtained by superposing the image of the input target object and stored figuration information of the target object.

An information display member has an information display face of its known size. On the information display face, a first pattern is displayed to represent coordinate information indicative of a position of the displayed information display member. On the information display face, a second pattern is displayed to represent direction information indicative of an direction in which the information display face is oriented. The information display face of the information display member is image-acquired by means of a camera, and an image is acquired. A direction in which the camera is oriented is obtained by a length ratio of aspect on the information display face mapped on the image and the direction information displayed on the information display face. A distance between the camera and the information display face is obtained by a size of the information display face mapped on the image. The position coordinate of the camera is obtained from the direction in which the camera is oriented the distance and the coordinate information displayed on the information display face.

A host computer searches an optical card for a file dated the same year as a screening file for a latest screening, which is to be recorded, at a search step, and determines at a first determination step whether a screening file dated the same year is present. When determining that a screening file dated the same year is present, the host computer extends control to a screening file recording step. When determining that a screening file dated the same year is absent, the host computer extends control to a regenerating step. The host computer then regenerates all screening files, which are dated the year for which no packed file has been created, from the optical card, and then determines at a second determination step whether the number of regenerated screening files exceeds 1. When it is determined that the number of regenerated screening files exceeds 1, control is passed to a packed file recording step. The regenerated screening files are then recorded all together as a packed file on the optical card. Control is then passed to a screening file recording step. When it is determined at the second determination step that the number of regenerated screening files is less than 1, control is passed to the screening file recording step. At the screening file recording step, the latest screening file is recorded on the optical card.
