Abstract

To provide a vehicular travel state monitoring device has functions of displaying images ahead of a traveling vehicle and data measured of a traveling state of the vehicle, such as accelerations acting on the vehicle, as images on the same screen and storing the displayed images as moving image data, a mobile terminal device has a vehicular travel state measuring means (13) built therein which includes a GPS (131), a three-axis acceleration sensor (132) and a three-axis angular velocity sensor (133). The mobile terminal device is further provided with a synthetic image generating means (16) which generates a synthetic image of a plurality of data synthesized at predetermined time intervals, out of measurement data measured by the vehicular travel state measuring means (13), imaging data captured by an imaging means (12), and Web information data acquired by a Web information acquiring unit (11a). The synthetic image is displayed on a display screen (17G) as a moving image, and data of the moving image are stored in a storage means (19) as travel record data of the vehicle.

Claims
