Further, the hole 30, the filter 32 is fitted in a position to block the whole of the hole 30. Filter 32 corresponds to a hatched portion in FIG. 1 (c), a neutral density filter 320H to reduce the amount of incident light, and a non-neutral density filter 320L colorless transparent corresponding to portions other than the hatched portion provided. Thus, the filter 32 functions as a so-called half-ND filter. The neutral density filter 320H occupies the upper portion of the filter 32 relative to the vertical "V" indicated by arrow, the non-neutral density filter 320L occupies a lower portion of the vertical direction V of the filter 32. Note that the "top of the vertical direction V ', relatively to the direction of gravity refers to a portion positioned in the opposite direction, the" lower part of the vertical direction V "relatively positioned in the direction of gravity It refers to the portion. Also, In the following, the "upward direction in the vertical direction V" refers to the direction opposite to the direction of gravity, and "downward direction in the vertical direction V" refers to the direction of gravity.

Thus, the filter 32 is within the range of the light to the camera 53 is incident, the amount of light incident on the top of the vertical direction V, reduced to than the amount of light incident on the lower portion of the vertical direction V. Thus, the filter 32 is an example of the "light amount reducing means" of the present invention.

The terminal device 50 includes a display surface 51 with a display unit such as is the liquid crystal display panel at the front side of the terminal device 50 main body, and a back 52 that is directed to the opposite side of the display surface 51. Usually, the terminal device 50 is configured in a rectangular plate shape, 52 back to the display surface 51 is substantially made parallel. In a state where the terminal device 50 is held in the terminal holding apparatus 1, the display surface 51, backward of the vehicle (rear) direction, i.e., oriented in a direction approximately the driver's seat as viewed from the dashboard is present, the back 52 , forward of the vehicle (forward) direction, i.e., is directed approximately windshield seen from the dashboard exists.

Further, the terminal device 50, the camera 53 is provided on the back 52. The camera 53 includes an imaging device, the photographed image on the basis of the light incident on the image pickup device (also simply referred to as "captured image".) To generate a. Specifically, the camera 53 has a field angle corresponding to the range of the light incident on the imaging device, in a state where the terminal device 50 is held in the terminal holding apparatus 1, performs photographing through the filter 32. The camera 53 is directed in a forward direction of the vehicle of the terminal holding apparatus 1. The camera 53 is an example of the "imaging device" of the present invention.

The terminal device 50 is displayed over the road surface continuously photographed image guidance display. That is, the terminal device 50 performs navigation based on the live-action video. For example, the terminal apparatus 50, based on various sensors such as GPS sensor or a gyro sensor, acquires information indicating the vehicle state location, and the like. Then, the terminal device 50 based on the information and the destination set by the user or a stop-off location, for example by referring to the map information stored in the memory, or by querying a server, specifying a travel route to the vehicle progresses to be displayed by superimposing the other guidance display arrow in the photographed image.

In this case, among the light incident on the imaging element of the camera 53, mainly 3 sky light is an enlarged view of the filter 32 near the light, i.e., below which passes the upper part of the vertical direction V incident, Figure 4 light passing between the illustrated as line "L1" and the line "L12" passes through a neutral density filter 320H. On the other hand, of the light incident on the imaging element of the camera 53, mainly passing between light light road surface passes below the vertical direction V of the incident, that is, the line "L2" in FIG. 3 the line L12 light passes through a non-neutral density filter 320L.

Thus, the terminal holding apparatus 1, depending on the exposure adjustment function of the camera 53, it is possible to prevent the road surface is captured dark working exposure adjustment function in accordance with the sky brightness when the air is bright. In other words, the terminal holding apparatus 1, even those exposure adjustment function of the camera 53 is simple, without depending on the performance, images important road be prevented from being underexposed when performing navigation can.

Structure of the terminal holder]
It will now be described in detail the structure of the terminal holder 20. Terminal holder 20, regardless of the angle to hold the terminal unit 50, among the light incident on the image pickup device of the camera 53, light incident on the upper part of the vertical direction V is, a position passing through the neutral density filter section 320H, placing neutral density filter 320H and non neutral density filter 320L.

Figure 2 shows a transparent state the back 29 of the terminal holder 20 in FIG. 1 (c). Specifically, FIG. 2 (a) is a state of arranging the terminal device 50 vertically relative to the terminal holder 20, the angle (simply "rotation angle of the terminal holder 20 with respect to this reference position, i.e. the base 11 or the like "and also referred to.) is set to 0 degrees of state. 2 (b) is being rotated about 45 degrees terminal holder 20 clockwise with respect to the support shaft 21, i.e. rotation angle of the terminal holder 20 is in a state of approximately 45 degrees. Here, for convenience of description, the clockwise and positive direction. FIG. 2 (c), being rotated about 90 degrees terminal holder 20 clockwise with respect to the support shaft 21, i.e., rotation angle of the terminal holder 20 is in a state of approximately 90 degrees. As described previously, the terminal device 50 typically has a rectangular plate shape, the vertical arrangement, an arrangement as the longitudinal direction of the display surface 51 is vertical, and arranged horizontally the longitudinal direction of the display surface 51 is arranged such that the side.

As shown in FIGS. 1 and 2, the support shaft 21 is fixed to the ball link 14 does not rotate. The first gear 24 is fixed to the support shaft 21, thus also does not rotate the first gear 24. The first gear 24 meshes with the second gear 25. The second gear 25 is rotatably fixed to the gear shaft 22, gear shaft 22 is fixed to the terminal holder 20. Further, the second gear 25 meshes with the third gear 26. The third gear 26 is rotatably fixed by a bearing unit 40 fixed on the terminal holder 20 illustrated in FIG. 3 to be described later. The first gear 24 to third gear 26 has a gear ratio of 1: 1, i.e., the ratio of the number of teeth 1: 1: is configured to 1. The first gear 24 to third gear 26 are both provided so as to be substantially parallel to the back 29 of the terminal holder 20.

Here will be specifically described with reference to FIG. 3 the structure of the third gear 26. Figure 3 is an example of a cross-sectional view according to cutting plane Aa-Ab of the third gear 26 shown in FIG. 2 (a). As shown in FIG. 3, the bearing unit 40 rotatably holding the third gear 26. Then, the teeth 261 of the third gear 26 is fitted into the groove 400 of the bearing portion 40. The bearing unit 40, with respect to the central axis of the third gear 26 to approximately match the one-dot chain line "L12" is rotated, under a load that acts in the vertical direction, and is fixed to the terminal holder 20.

The third gear 26 has a cavity 260 which forms part of a ring shape, holes 30 described above in its central portion. Filter 32 has a flat plate shape, it is mounted substantially parallel to the rotation axis perpendicular to the plane of the third gear 26. Specifically, of the cavity 260, shown within the dashed line frame, a filter 32 is fitted to the edge 262 of the inlet portion of the light is incident to the camera 53. Thus, light incident on the camera 53, passes through the filter 32 when passing through the hole 30 (cavity 260). That is, all of the imaging object of the camera 53 is taken via a filter 32. In FIG. 3, the angle formed by the broken line "L1" and "L2" corresponds to the angle of view of the camera 53 in the vertical direction V.

Referring again to FIG. 2, FIGS. 2 (a) to the position of the neutral density filter 320H and non neutral density filter 320L of the respective states of the (c) will be described. As shown in FIG. 2 (b), rotating the terminal holder 20 in the clockwise (the direction of arrow 70) relative to the support shaft 21 fixed to the ball links 14, first gear 24 is fixed to the support shaft 21 does not rotate because it is, the second gear 25 that meshes with the first gear 24 rotates clockwise (direction of arrow 71). Accordingly, a third gear 26 which meshes with the second gear 25 is rotated counterclockwise (the direction of arrow 72). As a result, as shown, the relative position with respect to the vertical direction V of the neutral density filter 320H and the non-neutral density filter 320L does not change. That is, the neutral density filter section 320H is arranged on top of the vertical direction V with respect to the non-neutral density filter 320L, non neutral density filter 320L is disposed below the vertical direction V with respect to the neutral density filter section 320H It is.

As shown in FIG. 2 (c), even by further rotating the terminal holder 20 clockwise, Similarly, the second gear 25 rotates clockwise, the third gear 26 with it is rotated counterclockwise to. As a result, the relative position with respect to the vertical direction V of the neutral density filter 320H and the non-neutral density filter 320L does not change.

Further, the vertical direction from the state in which the terminal holder 20 is in any rotation angle, even when rotated to the terminal holder 20 counterclockwise, similarly, the neutral density filter 320H and the non-neutral density filter 320L the relative position with respect to the V does not change. That is, in this case, the first gear 24 does not rotate, the second gear 25 rotates counter-clockwise, the third gear 26 that rotates clockwise, neutral density filter 320H and the non-neutral density filter relative positional relationship relative to the vertical direction V with 320L is maintained.

As described above, in this embodiment, engaging the first gear 24 to third gear 26, the first gear 24 is fixed, and the first gear 24 to the gear ratio of the third gear 26 1: 1 by, regardless rotation angle of the terminal holder 20 always neutral density filter 320H is held upward in a vertical direction V than the non-neutral density filter 320L.
