Abstract: Three objective lenses (11) having optical axes L oriented to different directions are mounted on a head portion (10) of an endoscope device. The objective lens (11) has a predetermined view angle ? centered by the optical axes L. Each objective lens (11) is disposed so as to have the peripheral portions of its viewing field overlap with the peripheral portions of the viewing fields of adjoining other objective lenses (11). Hence, the three objective lenses (11) causes the head portion (10) as a whole to have a view angle ? extending over a wider range than the view angle ? of the objective lens (11) with no discontinuation. Each optical image of a testing target part captured within this view angle ? is imaged by an imaging element.

Abstract: A road guide server (1) stores three-dimensional images of intersections included in road information on which images a reference orientation is defined in a three-dimensional image DB. The road information is stored in a map DB of a map data server (2) as information including information regarding roads and information regarding intersections on the roads. The road guide server (1) reads a three-dimensional image of a specified intersection in response to a request from a user terminal (3) connected thereto via a network (9), and generates an intersection guide image by combining a symbol indicating the road to be taken by the user on the read three-dimensional image in accordance with a guide route searched out by the map data server (2) based on the road information. The road guide server (1) sends the generated intersection guide image to the user terminal (3).

Abstract: A tilt adjustment section (400) tiltably holds a strut (200). A weight section (500), which applies a load to the strut in the direction of gravitational force, is attached to the strut (200). The load of the weight section (500) stabilizes the strut (200) in the direction of gravitational force. The tilt adjustment section (400) fixes the strut (200) in a state where the strut (200) is stabilized in the direction of gravitational force. A head (100) is connected to the strut (200). The strut (200) is rotatably connected to the tilt adjustment section (400). Therefore, the head (100) can be rotated without tilting the strut (200).
