<P>PROBLEM TO BE SOLVED: To confirm whether or not a face position is settled within an angle of view even in the case where a crew member of a vehicle is moved within a required range when adjusting a mounting direction of a camera device. <P>SOLUTION: A guide line 40 indicating an angle-of-view corresponding range 50 corresponding to an angle of view of a camera device 20 is drawn on the front side of a convex mirror 31. On the rear side of the convex mirror 31, a rear-side structure 32 is provided which includes a recess that is formed corresponding to the shape of a casing 21 of the camera device 20. An instrument 30 for the camera device comprised of the convex mirror 31 and the rear-side structure 32 is mounted in the camera device 20 while fitting the recess of the rear-side structure 32 to a front face 211 of the casing 21. At such a time, the angle-of-view corresponding range 50 is disposed with no inclination to a lens surface 221 at a position in front of a camera lens 22. Thus, a current imaging area of the camera device 20 can be projected on the angle-of-view corresponding range 50. The user confirms whether or not user's own face is settled within the angle-of-view corresponding range 50. <P>COPYRIGHT: (C)2013,JPO&INPIT |
