Abstract

The terminal holding device includes an attaching unit to be attached to a vehicle, a holding unit which removably holds a terminal device in such a manner that a display unit of the terminal device is exposed and which includes a contact surface to be contact with the terminal device, an acceleration sensor which detects acceleration in a direction from a side of the contact surface to a side opposite to the contact surface, and a supplying unit which supplies a detection signal of the acceleration sensor to the terminal device.

Claims

1. A navigation system comprising:

a terminal device including a camera and a display unit;

a holding unit which holds the terminal device such that the display unit and a lens of the camera are exposed; and

an attaching unit which attaches the holding unit to a movable body,

wherein the terminal device further comprises;

a generating unit which automatically extracts a part of images captured by the camera in accordance with a deviation of an image-capturing direction of the camera with respect to a traveling direction of the movable body to generate the images corresponding to the traveling direction of the movable body, and

a navigation processing unit which displays the images generated by the generating unit on the display unit to execute navigation processing for guiding the movable body.

2. The navigation system according to claim 1, wherein the movable body includes a vehicle.

3. The navigation system according to claim 1, further comprising an acceleration sensor mounted in a predetermined relation with the image-capturing direction of the camera,

wherein the generating unit generates the images corresponding to the traveling direction of the moving body.

4. The navigation system according to claim 1, wherein the camera is arranged on a back side of the display unit.

5. A terminal device moving together with a movable body, comprising:

an image-capturing unit;

a display unit;

a generating unit which automatically extracts a part of images captured by the image-capturing unit in accordance with a deviation of an image-capturing direction of the image-capturing unit with respect to a traveling direction of the movable body to generate the images corresponding to the traveling direction of the movable body; and

a navigation unit which displays the images generated by the generating unit on the display unit to execute navigation.

6. The terminal device according to claim 5, wherein the movable body includes a vehicle.

7. A computer program product stored in a non-transitory, tangible computer-readable medium readable by a computer, the computer program product executable by a terminal device moving together with a movable body and including an image-capturing unit and a display unit, the computer program product causing the computer to function as:

a display control unit which displays images captured by the image-capturing unit on the display unit;

a generating unit which automatically extracts a part of images captured by the image-capturing unit in accordance with a deviation of an image-capturing direction of the image-capturing unit with respect to a traveling direction of the movable body to generate the images corresponding to the traveling direction of the movable body; and

a navigation unit which displays the images generated by the generating unit on the display unit to execute navigation.
